 On August&amp;#xA0;11, 2014, the Company and Sanofi entered into the
 Sanofi License Agreement, which became effective on
 September&amp;#xA0;23, 2014. Under the terms of the Sanofi License
 Agreement, the Company granted to Sanofi exclusive, worldwide
 licenses to certain of the Company&amp;#x2019;s patents, trademarks and
 know-how for the development and commercialization of AFREZZA.
 Under the terms of the Sanofi License Agreement, Sanofi has the
 exclusive right and responsibility to develop AFREZZA worldwide,
 subject to certain development activities that will be performed by
 the Company. Sanofi will also be obligated to use commercially
 reasonable efforts to file for, obtain and maintain marketing
 approvals for AFREZZA in certain major markets and countries. In
 addition, Sanofi will have exclusive, worldwide rights to
 commercialize AFREZZA and will be obligated to use commercially
 reasonable efforts to market, promote and commercialize AFREZZA in
 all countries in the world where regulatory approval for AFREZZA
 has been received. Under the Sanofi License Agreement, Sanofi paid
 the Company an up-front cash payment of $150.0 million in the third
 quarter of 2014 and a subsequent payment of $50.0 million in the
 first quarter of 2015 for the achievement of two manufacturing
 milestones as of December&amp;#xA0;31, 2014. If certain development,
 regulatory and sales milestones are achieved, the Company will also
 be eligible to receive up to $725.0 million in additional milestone
 payments, of which $25.0 million relates to a development milestone
 event, $50.0 million relates to the filing and completion of
 regulatory approvals and $650.0 million relates to the achievement
 of certain product sales milestones. In addition, worldwide profits
 and losses, which are determined based on the difference between
 the net sales of AFREZZA and the costs and expenses incurred by the
 Company and Sanofi that are specifically attributable or related to
 the development, improvement, regulatory filings, manufacturing,
 and commercialization of AFREZZA will be shared 65% by Sanofi and
 35% by the Company. In accordance with the terms of the Sanofi
 License Agreement, profit and loss sharing commenced in the fourth
 quarter of 2014.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Pursuant to the terms of the Sanofi Supply Agreement, the Company
 will be the exclusive manufacturer and supplier of AFREZZA until
 the specified conditions are met, upon which a portion of the
 manufacturing activities may be assumed by Sanofi.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company analyzed the agreements entered into with Sanofi under
 the provisions of ASC 605,&amp;#xA0;&lt;i&gt;Revenue Recognition&lt;/i&gt;, to
 determine whether the consideration, or a portion thereof, could be
 recognized as revenue. ASC 605 provides that revenue is recognized
 when there is persuasive evidence that an arrangement exists,
 delivery has occurred or services have been rendered, the price is
 fixed or determinable and collection is reasonably assured. In
 addition, revenue arrangements with multiple elements are divided
 into separate units of accounting if certain criteria are met,
 including whether the delivered element has stand-alone value to
 the customer. When deliverables are separable, consideration
 received is allocated to the separate units of accounting based on
 the relative selling price of each deliverable and the appropriate
 revenue recognition principles are applied to each unit.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 1px &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The assessment of multiple element arrangements requires judgment
 in order to determine the appropriate units of accounting and the
 points in time that, or periods over which, revenue should be
 recognized. Under the terms of the Sanofi License Agreement, Sanofi
 Supply Agreement and the Sanofi Loan Facility the Company
 determined that the arrangement contained significant deliverables
 including (i)&amp;#xA0;licenses to develop and commercialize AFREZZA
 and to use the Company&amp;#x2019;s trademarks, (ii)&amp;#xA0;development
 activities, and (iii)&amp;#xA0;manufacture and supply services for
 AFREZZA. Due to the proprietary nature of the manufacturing
 services being provided by the Company, the Company determined that
 all of the significant deliverables should be combined into a
 single unit of accounting. The Company believes that the
 manufacturing services are proprietary due to the fact that since
 the late 1990&amp;#x2019;s, the Company has developed proprietary
 knowledge and patented equipment and tools that are used in the
 manufacturing process of AFREZZA. Due to the complexities of
 particle formulation and the specialized knowledge and equipment
 needed to handle the AFREZZA powder, neither Sanofi nor any

 In order for revenue to be recognized, the seller&amp;#x2019;s price to
 the buyer must be fixed and determinable. Given that as of
 March&amp;#xA0;31, 2015, the Company did not have the ability to
 estimate the amount of costs that would potentially be incurred
 under the loss share provision related to the Sanofi License
 Agreement and the Sanofi Supply Agreement, the Company believes
 this requirement for revenue recognition has not been met.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 As such, the Company did not recognize any revenue pursuant to the
 Sanofi License Agreement or the Sanofi Supply Agreement for the
 three months ended March&amp;#xA0;31, 2015. The Company has recorded
 the $150.0 million up-front payment and $50.0&amp;#xA0;million from
 milestone payments as deferred payments from collaboration. In
 addition, as of March&amp;#xA0;31, 2015 the Company has recorded
 $7.1&amp;#xA0;million in AFREZZA product shipments to Sanofi recorded
 as deferred product sales from collaboration and recorded
 $6.3&amp;#xA0;million as deferred product costs from collaboration.
 Deferred product costs represent the costs of product manufactured
 and shipped to Sanofi, not to exceed the amount of deferred product
 sales, for which recognition of revenue has been deferred. During
 the quarter ended March&amp;#xA0;31, 2015, the Company&amp;#x2019;s portion
 of the loss sharing was $12.4 million, which resulted in the
 reclassification from current deferred payments from collaboration
 to other long-term liabilities.&lt;/p&gt;

 &lt;i&gt;Sanofi Loan Facility&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 On September&amp;#xA0;23, 2014, the Company entered into the Sanofi
 Loan Facility, consisting of a senior secured revolving promissory
 note (the &amp;#x201C;Note&amp;#x201D;) and a guaranty and security agreement
 (the &amp;#x201C;Security Agreement&amp;#x201D;) with an affiliate of Sanofi
 which provides the Company with a secured loan facility of up to
 $175.0 million to fund the Company&amp;#x2019;s share of net losses
 under the Sanofi License Agreement. In the event of certain future
 defaults under the Sanofi Loan facility agreement for which the
 Company is not able to obtain waivers, the lender under the Sanofi
 Loan Facility may accelerate all of the Company&amp;#x2019;s repayment
 obligations, and take control of the Company&amp;#x2019;s pledged
 assets, potentially requiring the Company to renegotiate the terms
 of its indebtedness on terms less favorable to the Company, or to
 immediately cease operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Advances under the Sanofi Loan Facility bear interest at a rate of
 8.5%&amp;#xA0;per annum and are payable in-kind and compounded
 quarterly and added to the outstanding principal balance under the
 Sanofi Loan Facility. The Company is required to make mandatory
 prepayments on the outstanding loans under the Sanofi Loan Facility
 from its share of any Profits (as defined in the Sanofi License
 Agreement) under the Sanofi License Agreement within 30 days of
 receipt of its share of any such Profits. No advances may be made
 under the Sanofi Loan Agreement if Deerfield has commenced
 enforcement proceedings in connection with an event of default
 under the Facility Agreement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The outstanding principal of all loans under the Sanofi Loan
 Facility, if not prepaid, will become due and payable on
 September&amp;#xA0;23, 2024 unless accelerated pursuant to the terms of
 the Sanofi Loan Facility. Additionally, if the Company sells its
 Valencia facility, the Company is required to prepay the loans
 under the Sanofi Loan Facility in an amount equal to 100% of the
 net cash proceeds of the sale within five business days of
 receipt.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 In order to fund the Company&amp;#x2019;s portion of the loss sharing
 during the three months ended March&amp;#xA0;31, 2015, subsequent to
 March&amp;#xA0;31, 2015, the Company borrowed $12.4 million under the
 Sanofi Loan Facility to finance the portion of the Company&amp;#x2019;s
 loss. As of May&amp;#xA0;11, 2015, the total amount owed to Sanofi
 under the Sanofi Loan Facility was $15.5 million, which includes
 $0.1 million in paid-in-kind interest.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The obligations of the Company under the Sanofi Loan Facility are
 guaranteed by the Company&amp;#x2019;s wholly-owned subsidiary, MannKind
 LLC, and are secured by a first priority security interest in
 certain insulin inventory located in the United States and any
 contractual rights and obligations pursuant to which the Company
 purchases or has purchased such insulin, and a second priority
 security interest in the Company&amp;#x2019;s assets that secure the
 Company&amp;#x2019;s obligations under the Facility Agreement, as
 amended. In addition, the Company granted to Sanofi, as additional
 security for the obligations under the Sanofi Loan Facility, a
 first priority mortgage on the Company&amp;#x2019;s facility in
 Valencia, California.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Sanofi Loan Facility includes customary representations,
 warranties and covenants by the Company, including restrictions on
 its ability to incur additional indebtedness, grant certain liens
 and make certain changes to its organizational documents. Events of
 default under the Sanofi Loan Facility include: the Company&amp;#x2019;s
 failure to timely make payments due under the Sanofi Loan Facility;
 inaccuracies in the Company&amp;#x2019;s representations and warranties
 to the noteholder; the Company&amp;#x2019;s failure to comply with any
 of its covenants under any of the Sanofi Loan Facility or certain
 other related security agreements and documents entered into in
 connection with the Sanofi Loan Facility, subject to a cure period
 with respect to most covenants; the Company&amp;#x2019;s insolvency or
 the occurrence of certain bankruptcy-related events; termination by
 Sanofi of the Sanofi License Agreement as a result of the
 Company&amp;#x2019;s breach of the Sanofi License Agreement; and the
 failure of any material provision under any of the Sanofi Loan
 Facility or certain other related security agreements and documents
 entered into in connection with the Sanofi Loan Facility to remain
 in full force and effect. If one or more events of default occurs
 and is continuing, Sanofi may terminate its obligation to make
 advances under the Sanofi Loan Facility, and, if certain specified
 events of default (including the Company&amp;#x2019;s failure to timely
 make payments due under the Sanofi Loan Facility; the
 Company&amp;#x2019;s failure to comply with the negative covenants under
 the Sanofi Loan Facility limiting the Company&amp;#x2019;s ability to
 incur additional indebtedness or grant certain liens; the
 Company&amp;#x2019;s insolvency or the occurrence of certain
 bankruptcy-related events; termination by Sanofi of the Sanofi
 License Agreement as a result of the Company&amp;#x2019;s breach of the
 non-compete provisions of the Sanofi License Agreement; or the
 failure of any material provision under any of the Sanofi Loan
 Facility or certain other related security agreements and documents
 entered into in connection with the Sanofi Loan Facility to remain
 in full force and effect) occur and are continuing, the noteholder
 may accelerate all of the Company&amp;#x2019;s repayment obligations
 under the Sanofi Loan Facility and otherwise exercise any of its
 remedies as a secured creditor. There can be no assurance that the
 noteholder would not choose to exercise these rights in the event
 such events were to occur.&lt;/p&gt;

 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;&lt;i&gt;Guarantees and Indemnifications &amp;#x2014;&lt;/i&gt;&lt;/b&gt; In the
 ordinary course of its business, the Company makes certain
 indemnities, commitments and guarantees under which it may be
 required to make payments in relation to certain transactions. The
 Company, as permitted under Delaware law and in accordance with its
 Bylaws, indemnifies its officers and directors for certain events
 or occurrences, subject to certain limits, while the officer or
 director is or was serving at the Company&amp;#x2019;s request in such
 capacity. The term of the indemnification period is for the
 officer&amp;#x2019;s or director&amp;#x2019;s lifetime. The maximum amount of
 potential future indemnification is unlimited; however, the Company
 has a director and officer insurance policy that may enable it to
 recover a portion of any future amounts paid. The Company believes
 the fair value of these indemnification agreements is minimal. The
 Company has not recorded any liability for these indemnities in the
 accompanying condensed consolidated balance sheets. However, the
 Company accrues for losses for any known contingent liability,
 including those that may arise from indemnification provisions,
 when future payment is probable and the amount can be reasonably
 estimated.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;&lt;i&gt;Litigation &amp;#x2014;&lt;/i&gt;&lt;/b&gt; The Company is subject to legal
 proceedings and claims which arise in the ordinary course of its
 business. As of the date hereof, the Company believes that the
 final disposition of such matters will not have a material adverse
 effect on the financial position, results of operations or cash
 flows of the Company. The Company maintains liability insurance
 coverage to protect the Company&amp;#x2019;s assets from losses arising
 out of or involving activities associated with ongoing and normal
 business operations. In accordance with ASC 450
 &lt;i&gt;Contingencies&lt;/i&gt;, the Company would record a provision for a
 liability when it is both probable that a liability has been
 incurred and the amount of the loss can be reasonably
 estimated.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;&lt;i&gt;Contingencies &amp;#x2014;&lt;/i&gt;&lt;/b&gt; In connection with the Facility
 Agreement, on July&amp;#xA0;1, 2013 the Company also entered into a
 Milestone Rights Purchase Agreement (the &amp;#x201C;Milestone
 Agreement&amp;#x201D;) with Deerfield Private Design Fund and Horizon
 Sant&amp;#xE9; FLML S&amp;#xC1;RL (collectively, the &amp;#x201C;Milestone
 Purchasers&amp;#x201D;), pursuant to which the Company sold the
 Milestone Purchasers the Milestone Rights to receive payments up to
 $90.0 million upon the occurrence of specified strategic and sales
 milestones, including the first commercial sale of an AFREZZA
 product in the United States and the achievement of specified net
 sales figures (see Note 14 &amp;#x2013; Facility Agreement).&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;&lt;i&gt;Commitments &amp;#x2014;&lt;/i&gt;&lt;/b&gt; On July&amp;#xA0;31, 2014, the
 Company entered into the Insulin Supply Agreement, (the
 &amp;#x201C;Insulin Supply Agreement&amp;#x201D;), with&amp;#xA0;Amphastar France
 Pharmaceuticals S.A.S. (&amp;#x201C;Amphastar&amp;#x201D;), pursuant to which
 the Company agreed to purchase certain annual minimum quantities of
 insulin for an aggregate total purchase price of approximately
 &amp;#x20AC;120.1&amp;#xA0;million for calendar years 2015 through 2019.&lt;/p&gt;

 &lt;b&gt;14. Facility Agreement&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 As of March&amp;#xA0;31, 2015, there were $60.0 million principal
 amount of 2019 notes and $20.0 million principal amount of Tranche
 B notes outstanding. The 2019 notes accrue interest at annual rate
 of 9.75% and the Tranche B notes accrue interest at an annual rate
 of 8.75%. The Facility Agreement principal repayment schedule is
 comprised of annual payments beginning on July&amp;#xA0;1, 2016 and
 ending December&amp;#xA0;9, 2019. The repayment dates correspond to the
 dates on which the 2019 notes or Tranche B notes, as applicable,
 were issued.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 In conjunction with the Facility Agreement, the Company entered
 into a Milestone Rights Agreement with Deerfield which requires the
 Company to make contingent payments to Deerfield, totaling up to
 $90.0 million, upon the Company achieving specified
 commercialization milestones.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 The Milestone Rights were initially recorded as a short-term
 liability equal to $3.2 million included in accrued expenses and
 other current liabilities in the accompanying condensed
 consolidated balance sheet and a long-term liability equal to $13.1
 million included in other liabilities. During the three months
 ended March&amp;#xA0;31, 2015, the second milestone triggering event
 was achieved following the Company&amp;#x2019;s product launch on
 February&amp;#xA0;3, 2015, which resulted in a $5.8 million incremental
 charge to interest expense due to the increase in carrying value of
 the liability to the required $10.0 million payment made in
 February of 2015. As of March&amp;#xA0;31, 2015, the Company determined
 that it was probable that the first commercial sales related
 milestone would be achieved within the next twelve months. As such,
 the company reclassified the corresponding $1.6 million long term
 liability to short term. As of March&amp;#xA0;31, 2015, the short-term
 portion of the liability had a balance of $1.6 million and the
 long-term portion of the liability had a balance of $7.3
 million.&lt;/p&gt;

 The Facility Agreement contains a financial covenant that requires
 the Company&amp;#x2019;s cash and cash equivalents, which include
 available borrowings under the Loan Arrangement, on the last day of
 each fiscal quarter to not be less than $25.0 million. If the
 Company fails to satisfy this financial covenant, or another event
 of default occurs under the Facility Agreement, Deerfield may
 declare all or any portion of the 2019 notes and/or Tranche B notes
 to be immediately due and payable.&lt;/p&gt;

 &lt;b&gt;11. Net loss per common share&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 Basic net loss per share excludes dilution for potentially dilutive
 securities and is computed by dividing net loss by the weighted
 average number of common shares outstanding during the period
 excluding the shares loaned to Bank of America under a share
 lending arrangement (see Note 9 &amp;#x2014; Common and preferred
 stock). As of March&amp;#xA0;31, 2015, 9,000,000 shares of the
 Company&amp;#x2019;s common stock, which were loaned to Bank of America
 pursuant to the terms of a share lending agreement as described in
 Note 9, were issued and are outstanding, and the holder of the
 borrowed shares has all the rights of a holder of the
 Company&amp;#x2019;s common stock. However, because the share borrower
 must return all borrowed shares to the Company (or, in certain
 circumstances, the cash value thereof), the borrowed shares are not
 considered outstanding for the purpose of computing and reporting
 basic or diluted earnings (loss) per share. Diluted net loss per
 share reflects the potential dilution that could occur if
 securities or other contracts to issue common stock were exercised
 or converted into common stock. Potentially dilutive securities are
 excluded from the computation of diluted net loss per share for all
 of the periods presented in the accompanying condensed consolidated
 statements of operations because the reported net loss in each of
 these periods results in their inclusion being antidilutive.
 Antidilutive securities, which consist of stock options, restricted
 stock units, warrants, and shares that could be issued upon
 conversion of the senior convertible notes, that are not included
 in the diluted net loss per share calculation consisted of an
 aggregate of 45,171,595 shares and 67,791,150 shares as of
 March&amp;#xA0;31, 2015 and 2014, respectively, and exclude the
 9,000,000 shares loaned under the share lending arrangement.&lt;/p&gt;

 the amount of deferred costs (i.e., the asset would be realizable

 elected to account for the deferred costs related to the product
 sold to Sanofi as an asset and carry forward to future periods

 &lt;b&gt;5. Related-party arrangements&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 In October 2007, the Company entered into a $350.0 million loan
 arrangement with its principal stockholder. The Loan Arrangement
 has been amended from time to time. On October&amp;#xA0;31, 2013, the
 promissory note underlying the Loan Arrangement was amended to,
 among other things, extend the maturity date of the loan to
 January&amp;#xA0;5, 2020, extend the date through which the Company can
 borrow under the Loan Arrangement to December&amp;#xA0;31, 2019,
 increase the aggregate borrowing amount under the Loan Arrangement
 from $350.0 million to $370.0 million and provide that repayments
 or cancellations of principal under the Loan Arrangement will not
 be available for reborrowing.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 As of March&amp;#xA0;31, 2015, the total principal amount outstanding
 under the Loan Arrangement was $49.5 million, and the amount
 available for future borrowings was $30.1 million. Interest, at a
 fixed rate of 5.84%, is due and payable quarterly in arrears
 on&amp;#xA0;the first day of each calendar quarter for the preceding
 quarter, or at such other time as the Company and The Mann Group
 mutually agree. All or any portion of accrued and unpaid interest
 that becomes due and payable may be paid-in-kind and capitalized as
 additional borrowings at any time and would be classified as
 non-current upon mutual agreement of both parties. As of
 March&amp;#xA0;31, 2015, the Company had accrued $4.2 million of
 interest in other liabilities related to the Loan Arrangement. The
 Mann Group can require the Company to prepay up to $200.0 million
 in advances that have been outstanding for at least 12 months (less
 approximately $105.0 million aggregate principal amount that has
 been cancelled in connection with two common stock purchase
 agreements). If The Mann Group exercises this right, the Company
 will have 90 days after The Mann Group provides written notice (or
 the number of days to maturity of the note if less than
 90&amp;#xA0;days) to prepay such advances. However, pursuant to a
 letter agreement entered into in August 2010, The Mann Group has
 agreed to not require the Company to prepay amounts outstanding
 under the amended and restated promissory note if the prepayment
 would require the Company to use its working capital resources. The
 Mann Group entered into a subordination agreement with Deerfield
 pursuant to which The Mann Group agreed with Deerfield not to
 demand or accept any payment under the Loan Arrangement until the
 Company&amp;#x2019;s payment obligations to Deerfield under the Facility
 Agreement have been satisfied in full. Subject to the foregoing, in
 the event of a default under the Loan Arrangement, all unpaid
 principal and interest either becomes immediately due and payable
 or may be accelerated at The Mann Group&amp;#x2019;s option, and the
 interest rate will increase to the one-year LIBOR calculated on the
 date of the initial advance or in effect on the date of default,
 whichever is greater, plus 5%&amp;#xA0;per annum. All borrowings under
 the Loan Arrangement are unsecured. The Loan Arrangement contains
 no financial covenants.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 During the three months ended March&amp;#xA0;31, 2015, there were no
 additional borrowings under or amendments to the Loan

 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 As required by ASC 740 &lt;i&gt;Income Taxes&lt;/i&gt; (&amp;#x201C;ASC 740&amp;#x201D;),
 management of the Company has evaluated the positive and negative
 evidence bearing upon the realizability of its deferred tax assets
 and concluded, in accordance with the applicable accounting
 standards, that net deferred tax assets should be fully
 reserved.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 ASC 740-10-25 &lt;i&gt;Income Taxes Recognition&lt;/i&gt; clarifies the
 accounting and disclosure for uncertainty in tax positions, as
 defined. This guidance seeks to reduce the diversity in practice
 associated with certain aspects of the recognition and measurement
 related to accounting for income taxes. The Company believes that
 its income tax filing positions and deductions will be sustained on
 audit and does not anticipate any adjustments that will result in a
 material change to its financial position. Therefore, no reserves
 for uncertain income tax positions have been recorded pursuant to
 this guidance. Tax years since 1993 remain subject to examination
 by the major tax jurisdictions in which the Company is subject to
 tax.&lt;/p&gt;

 On August&amp;#xA0;18, 2010, the Company completed a Rule 144A offering
 of $100.0 million aggregate principal amount of 2015 notes. The
 2015 notes are governed by the terms of an indenture dated as of
 August&amp;#xA0;24, 2010 (the &amp;#x201C;2015 Note Indenture&amp;#x201D;). The
 2015 notes bear interest at the rate of 5.75%&amp;#xA0;per year on the
 principal amount, payable in cash semi-annually in arrears on
 February&amp;#xA0;15 and August&amp;#xA0;15 of each year, beginning
 February&amp;#xA0;15, 2011. In connection with the 2015 notes, the
 Company had accrued interest of $1.0 million and $2.4 million as of
 March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2014, respectively. The
 2015 notes are general, unsecured, senior obligations of the
 Company and effectively rank junior in right of payment to all of
 the Company&amp;#x2019;s secured debt, to the extent of the value of the
 assets securing such debt, and to the debt and all other
 liabilities of the Company&amp;#x2019;s subsidiaries. The maturity date
 of the 2015 notes is August&amp;#xA0;15, 2015 and payment is due in
 full on that date for unconverted securities. Holders of the 2015
 notes may convert, at any time prior to the close of business on
 the business day immediately preceding the stated maturity date,
 any outstanding principal into shares of the Company&amp;#x2019;s common
 stock at an initial conversion rate of 147.0859 shares per $1,000
 principal amount, which is equal to a conversion price of
 approximately $6.80 per share, subject to adjustment. Except in
 certain circumstances, if the Company undergoes a fundamental
 change: (1)&amp;#xA0;the Company will pay a make-whole premium on the
 2015 notes converted in connection with a fundamental change by
 increasing the conversion rate on such 2015 notes, which amount, if
 any, will be based on the Company&amp;#x2019;s common stock price and
 the effective date of the fundamental change, and (2)&amp;#xA0;each
 holder of 2015 notes will have the option to require the Company to
 repurchase all or any portion of such holder&amp;#x2019;s 2015 notes at
 a repurchase price of 100% of the principal amount of the 2015
 notes to be repurchased plus accrued and unpaid interest, if any.
 The Company may elect to redeem some or all of the 2015 notes if
 the closing stock price has equaled 150% of the conversion price
 for at least 20 of the 30 consecutive trading days ending on the
 trading day before the Company&amp;#x2019;s redemption notice. The
 redemption price will equal 100% of the principal amount of the
 2015 notes to be redeemed, plus accrued and unpaid interest, if
 any, up to, but excluding, the redemption date, plus a make-whole
 payment equal to the sum of the present values of the remaining
 scheduled interest payments through and including August&amp;#xA0;15,
 2015 (other than interest accrued up to, but excluding, the
 redemption date). The Company will be obligated to make the
 make-whole payment on all of the 2015 notes called for redemption
 and converted during the period from the date the Company mailed
 the notice of redemption to and including the redemption date. The
 Company may elect to make the make-whole payment in cash or shares
 of its common stock, subject to certain limitations. Under the
 terms of the 2015 Note Indenture, the conversion option can be
 net-share settled and the maximum number of shares that could be
 required to be delivered under the contract, including the
 make-whole shares, is fixed and less than the number of authorized
 and unissued shares less the maximum number of shares that could be
 required to be delivered during the contract period under existing
 commitments. Applying the Company&amp;#x2019;s sequencing policy, the
 Company performed an analysis at the time of the offering of the
 2015 notes and each reporting date since and has concluded that the
 number of available authorized shares at the time of the offering
 and each subsequent reporting date was sufficient to deliver the
 number of shares that could be required to be delivered during the
 contract period under existing commitments.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 The Company incurred approximately $4.2 million in issuance costs
 which are recorded as an offset to the 2015 notes in the
 accompanying condensed consolidated balance sheets. These costs are
 being accreted to interest expense using the effective interest
 method over the term of the 2015 notes.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 The 2015 notes provide that upon an acceleration of certain
 indebtedness, including the 9.75% Senior Convertible Notes due 2019
 (the &amp;#x201C;2019 notes&amp;#x201D;) and the 8.75% Senior Convertible
 Notes due 2019 (the &amp;#x201C;Tranche B notes&amp;#x201D;) issued to
 Deerfield pursuant to the Facility Agreement (see Note 14 &amp;#x2013;
 Facility Agreement), the holders may elect to accelerate the
 Company&amp;#x2019;s repayment obligations under the notes if such
 acceleration is not cured, waived, rescinded or annulled. There can
 be no assurance that the holders would not choose to exercise these
 rights in the event such events were to occur.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 Accretion of debt issuance expense in connection with the 2015
 notes during the three months ended March&amp;#xA0;31, 2015 and 2014
 was $238,000 and $223,000, respectively.&lt;/p&gt;

 The accompanying unaudited condensed consolidated financial

 United States of America (&amp;#x201C;GAAP&amp;#x201D;) for interim financial
 information and with the instructions to Form 10-Q and Article 10
 of Regulation S-X of the Securities and Exchange Commission (the

 information and footnotes required by GAAP for complete financial
 statements. The information included in this quarterly report on
 Form 10-Q should be read in conjunction with the audited
 consolidated financial statements and notes thereto included in the
 Company&amp;#x2019;s annual report on Form 10-K for the fiscal year
 ended December&amp;#xA0;31, 2014 filed with the SEC on March&amp;#xA0;2,

 In the opinion of management, all adjustments, consisting only of
 normal, recurring adjustments, considered necessary for a fair
 presentation of the results of these interim periods have been
 included. The results of operations for the three months ended
 March&amp;#xA0;31, 2015 may not be indicative of the results that may
 be expected for the full year.&lt;/p&gt;

 The preparation of financial statements in conformity with GAAP
 requires management to make estimates and assumptions that affect
 the amounts reported in the financial statements and accompanying
 notes. Actual results could differ from those estimates or
 assumptions. The more significant estimates reflected in these
 accompanying financial statements involve assessing long-lived
 assets and deferred product costs for impairment, accrued expenses,
 valuation of stock-based compensation and the determination of the
 provision for income taxes and corresponding deferred tax assets
 and liabilities and any valuation allowance recorded against net
 deferred tax assets. The estimation process often may yield a range
 of potentially reasonable estimates of the ultimate future outcomes
 and management must select an amount that falls within that range
 of reasonable estimates. This process may result in actual results
 differing materially from those estimated amounts used in the
 preparation of the financial statements.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Basis of Presentation&amp;#xA0;&lt;/i&gt;&lt;/b&gt;&amp;#x2014; The
 Company&amp;#x2019;s primary activities since incorporation have been
 establishing its facilities, recruiting personnel, conducting
 research and development, business development, business and
 financial planning, and raising capital. It is costly to develop
 therapeutic products and conduct associated clinical studies. As of
 March&amp;#xA0;31, 2015, the Company had an accumulated deficit of $2.5
 billion and a stockholders&amp;#x2019; deficit of $97.0&amp;#xA0;million.
 Historically the Company has reported negative cash flow from
 operations other than for the nine months ended September&amp;#xA0;30,
 2014 and for the three months ended March&amp;#xA0;31, 2015, as a
 result of receipt of the upfront payment and milestone payments
 under the Sanofi License Agreement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 At March&amp;#xA0;31, 2015, the Company&amp;#x2019;s capital resources
 consisted of cash and cash equivalents of $120.8 million. The
 Company expects to continue to incur significant expenditures to
 support commercial manufacturing of AFREZZA and the development of
 other product candidates. In addition, the Company had $232.5
 million principal amount of outstanding debt as of March&amp;#xA0;31,
 2015, including $100.0 million principal amount of outstanding
 5.75% Senior Convertible Notes due 2015 (the &amp;#x201C;2015
 notes&amp;#x201D;), which have a maturity date of August&amp;#xA0;15, 2015.
 See Note 5 &amp;#x2013; Related-party arrangements, Note 6 &amp;#x2013;
 Senior convertible notes, Note 7 &amp;#x2013; Collaboration
 arrangement&amp;#x2014;Sanofi Loan Facility, and Note 14 &amp;#x2013;
 Facility Agreement. In addition, the Company&amp;#x2019;s facility
 agreement (the &amp;#x201C;Facility Agreement&amp;#x201D;) with Deerfield
 Private Design Fund II, L.P. and Deerfield Private Design
 International II, L.P. (collectively, &amp;#x201C;Deerfield&amp;#x201D;) (see
 Note&amp;#xA0;14&amp;#xA0;&amp;#x2013; Facility Agreement) contains a financial
 covenant that requires the Company&amp;#x2019;s cash and cash
 equivalents, which include available borrowings under the
 Company&amp;#x2019;s loan arrangement (the &amp;#x201C;Loan
 Arrangement&amp;#x201D;) with The Mann Group LLC (&amp;#x201C;The Mann
 Group&amp;#x201D;), on the last day of each fiscal quarter to not be
 less than $25.0 million. Should the holders of the notes not elect
 to convert such notes into the Company&amp;#x2019;s common stock prior
 to their due date, the Company intends to refinance the 2015 notes
 or raise additional funds to settle the 2015 notes. The Company
 cannot be certain that it will achieve its projected cashflows or
 be able to refinance the 2015 notes, which raises substantial doubt
 about the Company&amp;#x2019;s ability to continue as a going concern.
 The financial statements do not include any adjustments that might
 result from the outcome of these uncertainties.&lt;/p&gt;

 On August&amp;#xA0;11, 2014, the Company executed a license and
 collaboration agreement (the &amp;#x201C;Sanofi License
 Agreement&amp;#x201D;) and a supply agreement (the &amp;#x201C;Sanofi Supply
 Agreement&amp;#x201D;) with Sanofi-Aventis Deutschland GmbH (which
 subsequently assigned its rights and obligations under the
 agreement to Sanofi-Aventis U.S. LLC (&amp;#x201C;Sanofi&amp;#x201D;)),
 pursuant to which Sanofi is responsible for global commercial,
 regulatory and development activities for AFREZZA. The Sanofi
 License Agreement became effective on September&amp;#xA0;23, 2014. The
 Company manufactures AFREZZA at its manufacturing facility in
 Danbury, Connecticut to supply Sanofi&amp;#x2019;s demand for the
 product. In addition, the Company and Sanofi are planning to
 collaborate to expand manufacturing capacity to meet global demand
 as necessary.&lt;/p&gt;

 Under the Sanofi License Agreement, Sanofi paid us an up-front cash
 payment of $150.0 million in the third quarter of 2014, and $50.0
 million in milestone payments in the first quarter of 2015. The
 foregoing milestone payments were earned as of December&amp;#xA0;31,
 2014. We are also eligible to receive up to $725.0 million in
 additional milestone payments under the Sanofi License Agreement if
 certain development, regulatory and sales milestones are achieved
 Worldwide profits and losses, which are determined based on the
 difference between the net sales of AFREZZA and the costs and
 expenses incurred by us and Sanofi that are specifically
 attributable or related to the development, regulatory filings,
 manufacturing, or commercialization of AFREZZA, will be shared 65%
 by Sanofi and 35% by us. In connection with the Sanofi License
 Agreement, an affiliate of Sanofi provided us with a secured loan
 facility (the &amp;#x201C;Sanofi Loan Facility&amp;#x201D;) of up to $175.0
 million to fund our share of net losses under the Sanofi License
 Agreement.&lt;/p&gt;

 Additional funding sources that are, or in certain circumstances
 may be available to the Company, include approximately
 $30.1&amp;#xA0;million principal amount of available borrowings under
 its Loan Arrangement (see Note 5 &amp;#x2013; Related-party
 arrangements), potential proceeds from the exercise of warrants
 issued in its February 2012 public offering of approximately $14.9
 million, and the Company&amp;#x2019;s at-the-market issuance sales
 agreements which allow the Company to sell up to $50.0 million in
 common stock provided no sales may be made except pursuant to an
 effective registration statement. The registration statement under
 which the shares that may be sold pursuant to the at-the-market
 issuance sales agreements are registered will expire in August
 2015. The Company cannot provide assurances that its plans will not
 change or that changed circumstances will not result in the
 depletion of its capital resources more rapidly than it currently
 anticipates. The Company may need to raise additional capital,
 whether through a sale of equity or debt securities, a strategic
 business collaboration with a pharmaceutical company, the
 establishment of other funding facilities, licensing arrangements,
 asset sales or other means, in order to continue the development
 and commercialization of AFREZZA and other product candidates and
 to support its other ongoing activities. However, the Company
 cannot provide assurances that such additional capital will be
 available on acceptable terms or at all.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Fair Value of Financial Instruments &amp;#x2014;&amp;#xA0;&lt;/i&gt;&lt;/b&gt;The carrying amounts

 their fair value due to their relatively short maturities. The fair
 value of the cash equivalents, note payable&amp;#xA0;to related party,
 senior convertible notes, and the Facility Agreement are discussed
 in Note 9 &amp;#x2013; Fair Value of Financial Instruments.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Deferred product costs from collaboration &amp;#x2014;&amp;#xA0;&lt;/i&gt;&lt;/b&gt;Deferred product costs
 represent the costs of product manufactured and shipped to Sanofi,
 not to exceed the amount of deferred product sales related to the
 collaboration, for which recognition of revenue has been deferred.
 Given that the costs of inventory delivered to a customer, but for
 which revenue may not yet be recognized, meet both the definition
 and characteristics of an &amp;#x201C;Asset&amp;#x201D; and the Company
 believes that it is probable that the amount of future revenue will
 exceed the amount of deferred costs (i.e., the asset would be
 realizable through the recognition of probable future income), the
 Company has elected to account for the deferred costs related to
 the product sold to Sanofi as an asset and carry forward to future
 periods until the related revenue is recognized.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Recently Issued Accounting Standards
 &amp;#x2014;&lt;/i&gt;&lt;/b&gt;&amp;#xA0;From time to time, new
 accounting pronouncements are issued by the Financial Accounting
 Standards Board (FASB) or other standard setting bodies that are
 adopted by the Company as of the specified effective date.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 In May&amp;#xA0;2014, a new standard was issued related to revenue
 recognition, which requires an entity to recognize the amount of
 revenue to which it expects to be entitled for the transfer of
 promised goods or services to customers. The guidance requires a
 company to recognize revenue to depict the transfer of goods or
 services to customers in an amount that reflects the consideration
 it expects to be entitled to receive in exchange for those goods or
 services. The standard is effective beginning the first quarter of
 the Company&amp;#x2019;s 2018 fiscal year (with early adoption not
 permitted) and may be adopted either by restating all years
 presented in the Company&amp;#x2019;s financial statements or by
 recording the impact of adoption as an adjustment to retained
 earnings at the beginning of fiscal 2018 The Company is assessing
 the potential impact of the new standard on its consolidated
 statements of financial position and results of operations and
 comprehensive income (loss) and has not yet selected a transition
 method.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 In August 2014, the FASB issued ASU 2014-15, which provides
 guidance on determining when and how reporting entities must
 disclose going-concern uncertainties in their financial statements.
 The new standard requires management to perform interim and annual
 assessments of an entity&amp;#x2019;s ability to continue as a going
 concern within one year of the date of issuance of the
 entity&amp;#x2019;s financial statements (or within one year after the
 date on which the financial statements are available to be issued,
 when applicable). Further, an entity must provide certain
 disclosures if there is &amp;#x201C;substantial doubt about the
 entity&amp;#x2019;s ability to continue as a going concern.&amp;#x201D; The
 ASU is effective for annual periods ending after December&amp;#xA0;15,
 2016, and interim periods thereafter; early adoption is permitted.
 The Company is evaluating the impact the adoption of ASU 2014-15
 will have on its consolidated financial statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 1px &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 In April 2015, the FASB issued ASU 2015 03, &amp;#x201C;Simplifying the
 Presentation of Debt Issuance Costs.&amp;#x201D; The guidance requires
 debt issuance costs to be presented in the balance sheet as a
 direct deduction from the carrying value of the associated debt,
 consistent with the presentation of a debt discount. The guidance
 is effective for annual reporting periods beginning after
 December&amp;#xA0;15, 2015 and interim periods thereafter. Early
 adoption is permitted. The Company does not believe the adoption of
 the new standard will have a material impact on its consolidated
 financial statements and disclosures.&lt;/p&gt;

 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 Total stock-based compensation expense recognized in the
 accompanying condensed consolidated statements of operations for
 the three months ended March&amp;#xA0;31, 2015 and 2014 was $2.0
 million and $5.2 million, respectively. The Company issued stock
 awards to employees during the three months ended March&amp;#xA0;31,
 2015 with a four-year vesting schedule. The grant date fair value
 of the 36,300 restricted stock units and 73,600 stock options
 issued was $262,086 and $382,720, respectively, with a grant date
 fair value per share of $7.22 and $5.20, respectively.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 As of March&amp;#xA0;31, 2015, there was $9.0 million and $10.0 million
 of unrecognized compensation cost related to options and restricted
 stock units, respectively, which are expected to be recognized over
 the remaining weighted average vesting period of 2.6 years. The
 Company evaluates stock awards with performance conditions as to
 the probability that the performance conditions will be met and
 estimates the date at which the performance conditions will be met
 in order to properly recognize stock-based compensation expense
 over the requisite service period. As of March&amp;#xA0;31, 2015, there
 were no unrecognized expenses related to performance options and
 restricted stock units, for milestones not considered probable of
 achievement.&lt;/p&gt;

 The Company applies various valuation approaches in determining the
 fair value of its financial assets and liabilities within a
 hierarchy that maximizes the use of observable inputs and minimizes
 the use of unobservable inputs by requiring that observable inputs
 be used when available. Observable inputs are inputs that market
 participants would use in pricing the asset or liability based on
 market data obtained from sources independent of the Company.
 Unobservable inputs are inputs that reflect the Company&amp;#x2019;s
 assumptions about the inputs that market participants would use in
 pricing the asset or liability and are developed based on the best
 information available in the circumstances. The fair value
 hierarchy is broken down into three levels based on the source of
 inputs as follows:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 75px; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Level 1&amp;#x2014; Quoted prices for identical instruments in active
 markets.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 75px; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Level 2&amp;#x2014; Quoted prices for similar instruments in active
 markets; quoted prices for identical or similar instruments in
 markets that are not active; and model-derived valuations whose
 inputs are observable or whose significant value drivers are
 observable.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 75px; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Level 3&amp;#x2014; Significant inputs to the valuation model are
 unobservable.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The availability of observable inputs can vary among the various
 types of financial assets and liabilities. To the extent that the
 valuation is based on models or inputs that are less observable or
 unobservable in the market, the determination of fair value
 requires more judgment. In certain cases, the inputs used to
 measure fair value may fall into different levels of the fair value
 hierarchy. In such cases, for financial statement disclosure
 purposes, the level in the fair value hierarchy within which the
 fair value measurement is categorized is based on the lowest level
 input that is significant to the overall fair value
 measurement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;i&gt;Cash and cash equivalents&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Cash equivalents consist of highly liquid investments with original
 or remaining maturities of 90 days or less at the time of purchase,
 that are readily convertible into cash. As of March&amp;#xA0;31, 2015
 and December&amp;#xA0;31, 2014, the Company held $120.8 million and
 $120.8 million, respectively, of cash and cash equivalents,
 consisting primarily of money market funds of $120.5 million and
 $118.5 million, respectively, and the remaining in non-interest
 bearing checking accounts. The fair value of these money market
 funds was determined by using quoted prices for identical
 investments in an active market (Level 1 in the fair value
 hierarchy).&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 The fair value of the note payable to our principal stockholder

 The estimated fair value of the 2015 notes was calculated based on
 model-derived valuations whose inputs were observable, such as the
 Company&amp;#x2019;s stock price, and non-observable, such as the
 Company&amp;#x2019;s longer-term historical volatility (Level 3 in the
 fair value hierarchy). As there is no current observable market for
 the 2015 notes, the Company determined the estimated fair value
 using a convertible bond valuation model within a lattice
 framework. The convertible bond valuation model combined expected
 cash outflows with market-based assumptions regarding risk-adjusted
 yields, stock price volatility and recent price quotes and trading
 information regarding Company issued debt instruments and shares of
 common stock into which the notes are convertible.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 As discussed in Note 14 &amp;#x2014; Facility Agreement, in connection
 with the Facility Agreement, the Company issued 2019 notes and
 certain rights to receive payments of up to $90.0 million upon the
 occurrence of specified strategic and sales milestones (the
 &amp;#x201C;Milestone Rights&amp;#x201D;). As there is no current observable
 market for the 2019 notes or Tranche B notes, the Company
 determined the estimated fair value using a bond valuation model
 based on a discounted cash flow methodology. The bond valuation
 model combined expected cash flows associated with principal
 repayment and interest based on the contractual terms of the debt
 agreement discounted to present value using a selected market
 discount rate. At March&amp;#xA0;31, 2015 the market discount rate was
 recalculated at 12.0% for the 2019 notes and 11.0% for the Tranche
 B notes (Level 3 in the fair value hierarchy).&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The estimated fair value of the Milestone Rights was calculated
 using the income approach in which the cash flows associated with
 the specified contractual payments were adjusted for both the
 expected timing and the probability of achieving the milestones
 discounted to present value using a selected market discount rate
 (Level 3 in the fair value hierarchy). The expected timing and
 probability of achieving the milestones, starting in 2014, was
 developed with consideration given to both internal data, such as
 progress made to date and assessment of criteria required for
 achievement, and external data, such as market research studies.
 The discount rate (15%)&amp;#xA0;was selected based on an estimation of
 required rate of returns for similar investment opportunities using
 available market data. As of March&amp;#xA0;31, 2015, the fair value of
 the Milestone Rights is estimated at $47.6 million.&lt;/p&gt;

 There were no material re-measurements to fair value during the
 three months ended March&amp;#xA0;31, 2015 of financial assets and
 liabilities that are not measured at fair value on a recurring
 basis.&amp;#xA0;There were no transfers of assets or liabilities
 between the fair value measurement levels during the three months
 ended March&amp;#xA0;31, 2015.&lt;/p&gt;

 As discussed in Note&amp;#xA0;7 &amp;#x2014; the Sanofi Loan Facility,
 consists of a senior secured revolving promissory note and a
 guaranty and security agreement with an affiliate of Sanofi which
 provides the Company with a secured loan facility of up to
 $175.0&amp;#xA0;million to fund the Company&amp;#x2019;s share of net losses
 under the Sanofi License Agreement. As of March&amp;#xA0;31, 2015, the
 Company borrowed $3.0&amp;#xA0;million under the Sanofi Loan Facility
 and the estimated fair value was determined to approximate the
 carrying value based on the consideration of the key elements of
 time value of money, namely the amount of time to settlement and
 the estimated discount rate appropriate for the liability. This
 analysis was performed using a discounted cash flow model in which
 time outstanding and discount rate were the primary variables.&lt;/p&gt;

 Included in the common stock outstanding as of March&amp;#xA0;31, 2015
 and December&amp;#xA0;31, 2014 are 9,000,000 shares of common stock
 loaned to Bank of America, N.A. under a share lending agreement in
 connection with the offering of $100.0 million aggregate principal
 amount of 2015 notes (see Note 6 &amp;#x2014; Senior convertible notes).
 Bank of America is obligated to return the borrowed shares (or, in
 certain circumstances, the cash value thereof) to the Company on or
 about the 45th business day following the date as of which the
 entire principal amount of the 2015 notes ceases to be outstanding,
 subject to extension or acceleration in certain circumstances or
 early termination at Bank of America&amp;#x2019;s option. The Company
 did not receive any proceeds from the sale of the borrowed shares
 by Bank of America, but the Company did receive a nominal lending
 fee of $0.01 per share from Bank of America for the use of borrowed
 shares.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Basis of Presentation&amp;#xA0;&lt;/i&gt;&lt;/b&gt;&amp;#x2014; The
 Company&amp;#x2019;s primary activities since incorporation have been
 establishing its facilities, recruiting personnel, conducting
 research and development, business development, business and
 financial planning, and raising capital. It is costly to develop
 therapeutic products and conduct associated clinical studies. As of
 March&amp;#xA0;31, 2015, the Company had an accumulated deficit of $2.5
 billion and a stockholders&amp;#x2019; deficit of $97.0&amp;#xA0;million.
 Historically the Company has reported negative cash flow from
 operations other than for the nine months ended September&amp;#xA0;30,
 2014 and for the three months ended March&amp;#xA0;31, 2015, as a
 result of receipt of the upfront payment and milestone payments
 under the Sanofi License Agreement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 At March&amp;#xA0;31, 2015, the Company&amp;#x2019;s capital resources
 consisted of cash and cash equivalents of $120.8 million. The
 Company expects to continue to incur significant expenditures to
 support commercial manufacturing of AFREZZA and the development of
 other product candidates. In addition, the Company had $232.5
 million principal amount of outstanding debt as of March&amp;#xA0;31,
 2015, including $100.0 million principal amount of outstanding
 5.75% Senior Convertible Notes due 2015 (the &amp;#x201C;2015
 notes&amp;#x201D;), which have a maturity date of August&amp;#xA0;15, 2015.
 See Note 5 &amp;#x2013; Related-party arrangements, Note 6 &amp;#x2013;
 Senior convertible notes, Note 7 &amp;#x2013; Collaboration
 arrangement&amp;#x2014;Sanofi Loan Facility, and Note 14 &amp;#x2013;
 Facility Agreement. In addition, the Company&amp;#x2019;s facility
 agreement (the &amp;#x201C;Facility Agreement&amp;#x201D;) with Deerfield
 Private Design Fund II, L.P. and Deerfield Private Design
 International II, L.P. (collectively, &amp;#x201C;Deerfield&amp;#x201D;) (see
 Note&amp;#xA0;14&amp;#xA0;&amp;#x2013; Facility Agreement) contains a financial
 covenant that requires the Company&amp;#x2019;s cash and cash
 equivalents, which include available borrowings under the
 Company&amp;#x2019;s loan arrangement (the &amp;#x201C;Loan
 Arrangement&amp;#x201D;) with The Mann Group LLC (&amp;#x201C;The Mann
 Group&amp;#x201D;), on the last day of each fiscal quarter to not be
 less than $25.0 million. Should the holders of the notes not elect
 to convert such notes into the Company&amp;#x2019;s common stock prior
 to their due date, the Company intends to refinance the 2015 notes
 or raise additional funds to settle the 2015 notes. The Company
 cannot be certain that it will achieve its projected cashflows or
 be able to refinance the 2015 notes, which raises substantial doubt
 about the Company&amp;#x2019;s ability to continue as a going concern.
 The financial statements do not include any adjustments that might
 result from the outcome of these uncertainties.&lt;/p&gt;

 On August&amp;#xA0;11, 2014, the Company executed a license and
 collaboration agreement (the &amp;#x201C;Sanofi License
 Agreement&amp;#x201D;) and a supply agreement (the &amp;#x201C;Sanofi Supply
 Agreement&amp;#x201D;) with Sanofi-Aventis Deutschland GmbH (which
 subsequently assigned its rights and obligations under the
 agreement to Sanofi-Aventis U.S. LLC (&amp;#x201C;Sanofi&amp;#x201D;)),
 pursuant to which Sanofi is responsible for global commercial,
 regulatory and development activities for AFREZZA. The Sanofi
 License Agreement became effective on September&amp;#xA0;23, 2014. The
 Company manufactures AFREZZA at its manufacturing facility in
 Danbury, Connecticut to supply Sanofi&amp;#x2019;s demand for the
 product. In addition, the Company and Sanofi are planning to
 collaborate to expand manufacturing capacity to meet global demand
 as necessary.&lt;/p&gt;

 Under the Sanofi License Agreement, Sanofi paid us an up-front cash
 payment of $150.0 million in the third quarter of 2014, and $50.0
 million in milestone payments in the first quarter of 2015. The
 foregoing milestone payments were earned as of December&amp;#xA0;31,
 2014. We are also eligible to receive up to $725.0 million in
 additional milestone payments under the Sanofi License Agreement if
 certain development, regulatory and sales milestones are achieved
 Worldwide profits and losses, which are determined based on the
 difference between the net sales of AFREZZA and the costs and
 expenses incurred by us and Sanofi that are specifically
 attributable or related to the development, regulatory filings,
 manufacturing, or commercialization of AFREZZA, will be shared 65%
 by Sanofi and 35% by us. In connection with the Sanofi License
 Agreement, an affiliate of Sanofi provided us with a secured loan
 facility (the &amp;#x201C;Sanofi Loan Facility&amp;#x201D;) of up to $175.0
 million to fund our share of net losses under the Sanofi License
 Agreement.&lt;/p&gt;

 Additional funding sources that are, or in certain circumstances
 may be available to the Company, include approximately
 $30.1&amp;#xA0;million principal amount of available borrowings under
 its Loan Arrangement (see Note 5 &amp;#x2013; Related-party
 arrangements), potential proceeds from the exercise of warrants
 issued in its February 2012 public offering of approximately $14.9
 million, and the Company&amp;#x2019;s at-the-market issuance sales
 agreements which allow the Company to sell up to $50.0 million in
 common stock provided no sales may be made except pursuant to an
 effective registration statement. The registration statement under
 which the shares that may be sold pursuant to the at-the-market
 issuance sales agreements are registered will expire in August
 2015. The Company cannot provide assurances that its plans will not
 change or that changed circumstances will not result in the
 depletion of its capital resources more rapidly than it currently
 anticipates. The Company may need to raise additional capital,
 whether through a sale of equity or debt securities, a strategic
 business collaboration with a pharmaceutical company, the
 establishment of other funding facilities, licensing arrangements,
 asset sales or other means, in order to continue the development
 and commercialization of AFREZZA and other product candidates and
 to support its other ongoing activities. However, the Company
 cannot provide assurances that such additional capital will be
 available on acceptable terms or at all.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Business &amp;#x2014;&lt;/i&gt;&lt;/b&gt; MannKind is a biopharmaceutical
 company focused on the discovery and development of therapeutic
 products for diseases such as diabetes. Our only approved product,
 AFREZZA (insulin human [rDNA origin]) inhalation powder, is a
 rapid-acting inhaled insulin that was approved by the U.S. Food and
 Drug Administration (the &amp;#x201C;FDA&amp;#x201D;) on June&amp;#xA0;27, 2014
 to improve glycemic control in adult patients with diabetes. In
 August 2014, we entered into a license and collaboration agreement
 (the &amp;#x201C;Sanofi License Agreement&amp;#x201D;) with Sanofi-Aventis
 Deutschland GmbH (which subsequently assigned its rights and
 obligations under the agreement to Sanofi-Aventis U.S. LLC
 (&amp;#x201C;Sanofi&amp;#x201D;)), pursuant to which Sanofi conducts all
 sales and marketing activities related to AFREZZA (see Note&amp;#xA0;7
 &amp;#x2013; Collaboration arrangement). AFREZZA became available by
 prescription in United States retail pharmacies in February
 2015.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Recently Issued Accounting Standards &amp;#x2014;&lt;/i&gt;&lt;/b&gt; From
 time to time, new accounting pronouncements are issued by the
 Financial Accounting Standards Board (FASB) or other standard
 setting bodies that are adopted by the Company as of the specified
 effective date.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 In May&amp;#xA0;2014, a new standard was issued related to revenue
 recognition, which requires an entity to recognize the amount of
 revenue to which it expects to be entitled for the transfer of
 promised goods or services to customers. The guidance requires a
 company to recognize revenue to depict the transfer of goods or
 services to customers in an amount that reflects the consideration
 it expects to be entitled to receive in exchange for those goods or
 services. The standard is effective beginning the first quarter of
 the Company&amp;#x2019;s 2018 fiscal year (with early adoption not
 permitted) and may be adopted either by restating all years
 presented in the Company&amp;#x2019;s financial statements or by
 recording the impact of adoption as an adjustment to retained
 earnings at the beginning of fiscal 2018 The Company is assessing
 the potential impact of the new standard on its consolidated
 statements of financial position and results of operations and
 comprehensive income (loss) and has not yet selected a transition
 method.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 In August 2014, the FASB issued ASU 2014-15, which provides
 guidance on determining when and how reporting entities must
 disclose going-concern uncertainties in their financial statements.
 The new standard requires management to perform interim and annual
 assessments of an entity&amp;#x2019;s ability to continue as a going
 concern within one year of the date of issuance of the
 entity&amp;#x2019;s financial statements (or within one year after the
 date on which the financial statements are available to be issued,
 when applicable). Further, an entity must provide certain
 disclosures if there is &amp;#x201C;substantial doubt about the
 entity&amp;#x2019;s ability to continue as a going concern.&amp;#x201D; The
 ASU is effective for annual periods ending after December&amp;#xA0;15,
 2016, and interim periods thereafter; early adoption is permitted.
 The Company is evaluating the impact the adoption of ASU 2014-15
 will have on its consolidated financial statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt"&gt;
 In April 2015, the FASB issued ASU 2015 03, &amp;#x201C;Simplifying the
 Presentation of Debt Issuance Costs.&amp;#x201D; The guidance requires
 debt issuance costs to be presented in the balance sheet as a
 direct deduction from the carrying value of the associated debt,
 consistent with the presentation of a debt discount. The guidance
 is effective for annual reporting periods beginning after
 December&amp;#xA0;15, 2015 and interim periods thereafter. Early
 adoption is permitted. The Company does not believe the adoption of
 the new standard will have a material impact on its consolidated
 financial statements and disclosures.&lt;/p&gt;
