SILVER SPRING, Md. and RESEARCH TRIANGLE PARK, N.C., April 19, 2021 /PRNewswire/ -- United Therapeutics Corporation (Nasdaq: UTHR) today announced the submission of a new drug application (NDA) to the U.S. Food and Drug Administration (FDA) for Tyvaso DPI™, a novel dry powder inhalation formulation of treprostinil, for the treatment of pulmonary arterial hypertension (PAH; WHO Group 1 pulmonary hypertension) and pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3 pulmonary hypertension). There are approximately 45,000 treated PAH patients in the U.S. and United Therapeutics estimates at least 30,000 treatable PH-ILD patients in the U.S.
The submission includes the results of the recently-completed BREEZE clinical study evaluating the use of Tyvaso DPI in PAH patients transitioning from Tyvaso® (treprostinil) Inhalation Solution, along with additional pharmacokinetic data from a study in healthy volunteers.
'In the BREEZE and pharmacokinetic studies, Tyvaso DPI demonstrated safety, tolerability, and a comparable pharmacokinetic profile to nebulized Tyvaso Inhalation Solution,' said Leigh Peterson, Ph.D., Senior Vice President, Product Development at United Therapeutics. 'If approved by the FDA, we expect Tyvaso DPI will provide an advancement in the delivery of inhaled treprostinil therapy.'
'Since our founding, we've worked hard to ensure our patients have ample choices to deliver treprostinil in various ways to suit their individual needs,' said Gil Golden, M.D., Ph.D., Chief Medical Officer of United Therapeutics. 'If approved, Tyvaso DPI will enable patients to go about their day with just a small breath-actuated, dry powder inhaler that easily fits inside a pocket and requires no batteries or external power source to operate.'
'We're excited for the potential for Tyvaso DPI to be one of our next product launches, assuming a timely approval in December of this year,' said Michael Benkowitz, President and Chief Operating Officer of United Therapeutics. 'The patient choice afforded by Tyvaso DPI, if approved, will help us achieve our goal of doubling the number of patients on Tyvaso therapy by the end of 2022. We remain committed to investigating, innovating, and delivering multiple therapies and treatments designed to help our patients manage their conditions.'
United Therapeutics has applied a priority review voucher to the NDA that could provide for an FDA decision by December 2021. The FDA must first accept the application for review and issue a formal decision date in accordance with the Prescription Drug User Fee Act.
Tyvaso DPI is an investigational therapy that is not approved for any use in any country or indication and the Tyvaso DPI tradename is pending final FDA review. United Therapeutics expects to present data from the BREEZE study and the pharmacokinetic study in healthy volunteers at upcoming medical conferences and in forthcoming scientific publications.
About Tyvaso DPI™
Tyvaso DPI™ is an investigational drug-device combination therapy comprised of a dry powder formulation of treprostinil and a small, portable, dry powder inhaler. If approved, Tyvaso DPI is expected to provide a more convenient method of administration compared with traditional nebulized Tyvaso® therapy. United Therapeutics is developing Tyvaso DPI under a collaboration and license agreement with MannKind Corporation (Nasdaq: MNKD). Tyvaso DPI incorporates the dry powder formulation technology and Dreamboat® inhalation device technology used in MannKind's Afrezza® (insulin human) Inhalation Powder product, which was approved by the FDA in 2014.
United Therapeutics and MannKind are also developing BluHale®, a Bluetooth-connected accessory for the Tyvaso DPI inhaler with a companion mobile application intended to help the patient track information about inhaler use.
