MannKind and United Therapeutics Achieve a Major Milestone in the Development of Tyvaso DPI™ With New Drug Application Acceptance From the FDA

06/16/21
  • Tyvaso DPI includes the second compound formulated with MannKind’s Technosphere® technology to be reviewed by the FDA
  • FDA review expected to be complete in October 2021
  • Hiring expansion underway at MannKind’s manufacturing facility in Connecticut

DANBURY, Conn., June 16, 2021 (GLOBE NEWSWIRE) -- MannKind Corporation (Nasdaq: MNKD) and United Therapeutics Corporation (Nasdaq: UTHR) reached a major milestone today with the announcement that the U.S. Food and Drug Administration (FDA) accepted for priority review of the New Drug Application (NDA) for Tyvaso DPI™ (inhaled treprostinil) for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD). The development marks the second compound formulated with MannKind’s Technosphere® technology to be reviewed by the FDA, which is expected to be complete in October 2021. The FDA has also indicated that they have not identified any potential review issues at this time.

A next-generation formulation of treprostinil, Tyvaso DPI incorporates the dry powder formulation technology and Dreamboat® inhalation device technology used in MannKind’s Afrezza® (insulin human) Inhalation Powder, which was approved by the FDA in 2014. MannKind and United Therapeutics are also developing BluHale®, a Bluetooth-connected accessory for the Tyvaso DPI inhaler with a companion mobile application intended to help patients track information about their inhaler use.

“We are energized by the acceptance of the Tyvaso DPI NDA for priority review,” said Michael Castagna, PharmD, Chief Executive Officer of MannKind Corporation. “MannKind is driven to deliver therapeutics in ways that can help improve patient lives for the better. With this key regulatory step, we are excited to progress the next Technosphere product towards providing thousands of PAH and PH-ILD patients a more convenient method of treprostinil therapy administration.”

MannKind and United Therapeutics entered into a worldwide exclusive licensing and collaboration agreement in September 2018 for the development and commercialization of Tyvaso DPI. In its communications with United Therapeutics, the FDA indicated that approval of the NDA will be subject to an inspection of the Tyvaso DPI manufacturing facility operated by MannKind; FDA and MannKind have jointly targeted the third quarter of 2021 to complete the inspection.  

The NDA includes data from the BREEZE clinical study that demonstrated safety and tolerability of Tyvaso DPI in patients with PAH transitioning from Tyvaso® (treprostinil) Inhalation Solution. A separate study in healthy volunteers demonstrated comparable treprostinil exposure between Tyvaso DPI and Tyvaso Inhalation Solution.

MannKind is entering an expansion phase as it prepares to transition from producing clinical supply to building pre-launch inventory of Tyvaso DPI, pending FDA approval. The company’s manufacturing and R&D facility in Danbury is scaling up by hiring more than 100 positions, as well as readying essential equipment and production lines. A variety of MannKind jobs in commercial manufacturing, engineering, quality control, warehouse operations, maintenance, and more are currently open and planned to be filled this year. Positions include both non-exempt and exempt positions.

“It’s exciting to bring growth and expansion to Danbury and the surrounding communities as MannKind continues to build upon its Technosphere® technology,” said Joe Kocinsky, MS, MBA, Chief Technology Officer of MannKind Corporation. “Our site will practically double in size as we spend the next months preparing for Tyvaso DPI, pending FDA approval.”
