What exactly is the Technosphere® Platform?

One of the largest organs in your body are the lungs. Picture the size of a full tennis court and that is roughly the surface area of both lungs in a typical adult. Running through those lungs are airways whose total length measures 1,500 miles – that’s the distance between Chicago and Las Vegas, New York to Albuquerque, and Los Angeles to Nashville.

Simply put, the lungs create a wonderful platform for effective drug delivery. MannKind’s Technosphere technology recognizes this and provides the distinct advantage of rapid, deep lung drug delivery. The effect is similar to intravenous delivery (I.V.; within a vein) and has the added benefit of bypassing the liver which can be especially helpful in reducing systemic side effects.

Examining it closer, it helps to look at inhalation, air flow travel, and the exhale. When you breathe in, air is drawn into the lung and flows down curving, narrowing airways that end in the air sacs or alveoli. When air is exhaled, the flow is reversed. Between the end of an inhalation and the start of exhalation, the air in the lung is stationary. To reach the deep lung, inhaled particles must be carried by the air stream and have enough momentum to continue through the stationary air to collide with the lung surface.

Particles that can reach the lung have aerodynamic diameters between 0.5 µm and 5-6 µm (1 µm is 1 micro-meter or about 0.00004 inches). Particles that are larger than 6 µm will leave the air stream and hit the back of your mouth and throat; smaller than 0.5 µm wouldn’t have the ability to reach the lungs and would simply get exhaled.

“The average Technosphere particle is about 2-2.5 µm which is in the middle of the respirable range,” explains Marshall Grant, PhD, MSc, Executive Director, Clinical Pharmacology & Research for MannKind Corporation. “The particle size distribution is a major reason Technosphere powders are highly efficient in delivering drug to the lungs than other dry powder inhalers (DPIs).”

The Technosphere particles in FDA-approved Afrezza® (insulin human) Inhalation Powder and Tyvaso DPI™ (treprostinil) Inhalation Powder are manufactured by different processes and possess different characteristics. But both are made up of small crystals of FDKP (fumaryl diketopiperazine), MannKind’s proprietary molecule. FDKP provides high solubility and fast dissolution at physiologic pH – and more importantly – can crystallize and form particles in the range appropriate for optimum delivery to the lungs.

When Technosphere powder reaches the lung surface, the FDKP and drug dissolve. The FDKP is then rapidly cleared from the lung into systemic circulation. The FDKP is not metabolized, but rather excreted primarily in the urine. Another value of Technosphere powders has been their versatility – they are compatible with a wide range of doses with different types of drugs.

MannKind’s Technosphere powders are delivered into the lung’s airstream via an inhalation device or DPI (dry powder inhaler). The breath-powered inhalers (Dreamboat® being the most common version) provide excellent delivery efficiency and are proven to deliver up to 70% of the dry-powder dose deep into the lungs. Our DPI are designed to be simple, easy to use and discreet. For patients, imagine having a drug in the convenient form of an inhaler that fits in the palm of your hand. This approach allows patients to not only take control of their health but do it while going about their day and enjoying life more humann.

NTM Lung Disease on the Rise

“I cough every morning upon waking, so I don’t feel rested.” “Imagine not being able to breathe.” “Anxiety ruins everything about you – it’s not a normal life.” “You just exist from day to day and week to week.” These are a sampling of comments about the most bothersome symptoms from living with Nontuberculous Mycobacteria (NTM) shared in a study from NTM Info & Research, Inc. The statements are unfortunately typical and those with NTM often have unpredictable day-to-day health functioning and reduced quality of life.

NTM lung disease is a serious infection that is caused by bacteria that are common in the environment and can cause lung damage. The reality is that we are all exposed to these bacteria in our day-to-day lives – more than 120 species of mycobacteria have been identified. These common bacteria exist in water and soil particles that are in the air, wet places like hot tubs, steamy bathrooms, dishwashers, and even the dewy ground we walk on at the park. But not everyone is at risk of getting NTM lung disease just because they are exposed.

Those predisposed often have underlying conditions such as asthma, COPD, and bronchiectasis, which makes them prone to NTM infection. NTM is not considered to be contagious. Women over the age of 65 make up the majority of those impacted, with a predominance in those of Caucasian and Asian descent.

A rare disease, NTM can often be difficult to diagnose. Many will experience coughing, fatigue, weight loss and shortness of breath – all of which are common with other lung disease symptoms and other conditions like tuberculosis. With NTM, symptoms often worsen, and that is a marker not to be ignored.

It is estimated that some 86,000 individuals are living with NTM lung diseases, and it is on the rise growing 8% each year. Coastal regions including Gulf States have higher rates of infection accounting for 70% of annual NTM cases.

While no cure is available, treatments to manage NTM are available. Treatment for NTM involves antibiotic and multidrug regimens with duration lasting from months to years with tolerability and adverse reactions to treatment which often leads to a lack of adherence to therapy.

There is a valuable need to develop medicines that are well tolerated and effective that lends to consistent patient use and alleviates symptoms of NTM lung disease. MannKind continues to progress MNKD-101 (Clofazimine) for the treatment of NTM.

MannKind Corporation Reports Fourth Quarter and Full Year 2005 Financial Results

- Conference Call to Begin Today at 9:00 a.m. ET -

VALENCIA, Calif., Feb 06, 2006 /PRNewswire-FirstCall via COMTEX News Network/ -- MannKind Corporation (Nasdaq: MNKD) today reported financial results for the fourth quarter and year ended December 31, 2005.

For the fourth quarter of 2005, total operating expenses were $35.0 million, compared with $21.7 million for the fourth quarter of 2004. Research and development (R&D) expenses increased by $8.1 million to $28.6 million for the fourth quarter of 2005 compared to the fourth quarter of 2004, primarily due to increased costs associated with the Company's expanded clinical development program for Technosphere® Insulin, which is currently in Phase 3 clinical trials in the U.S. and Europe. General and administrative (G&A) expenses increased by $5.3 million to $6.5 million for the fourth quarter of 2005 compared to the fourth quarter of 2004 primarily due to changes in stock compensation expense and increased consulting and various other general and administrative expenses, such as legal and accounting fees.

The net loss applicable to common stockholders for the fourth quarter of 2005 was $33.3 million, or $0.66 per share based on 50.3 million shares outstanding, compared with a net loss applicable to common stockholders of $21.2 million, or $0.65 per share based on 32.8 million shares outstanding, for the fourth quarter of 2004.

For the year ended December 31, 2005, total operating expenses were $118.1 million, compared with $77.1 million for 2004. R&D expenses were $95.3 million in 2005, up $35.9 million from 2004, primarily related to the expansion of clinical trials of the Technosphere Insulin program. G&A expenses increased by $5.1 million to $22.8 million for 2005 as compared to 2004 primarily related to increased compensation and other employee related costs and increased legal, accounting and consulting fees. The net loss applicable to common stockholders for 2005 was $114.3 million, or $2.87 per share based on 39.9 million shares outstanding, compared with a net loss applicable to common stockholders of $95.9 million, or $3.80 per share based on 25.2 million shares outstanding for 2004.

"2005 was an exceptional year for MannKind," said Alfred Mann, Chairman and Chief Executive Officer of MannKind Corporation. "In addition to strengthening our balance sheet and expanding our management team, we added to the growing evidence of the safety, efficacy, and other differentiating qualities of our lead investigational product candidate, Technosphere Insulin, an inhalable form of insulin for type 1 and type 2 diabetes."

Hakan Edstrom, President and Chief Operating Officer of MannKind Corporation added, "In recent clinical trials, we observed that the Technosphere Insulin System reduces blood glucose excursions following a meal compared to the effect seen with oral or injectable diabetes medications. At the same time, Technosphere Insulin appears to reduce the risk of late postprandial hypoglycemia commonly associated with other diabetes products, without any evidence of weight gain or deterioration in pulmonary function."
