MannKind Opens Enrollment of Phase 1 Trial of Treprostinil Technosphere for Pulmonary Arterial Hypertension

WESTLAKE VILLAGE, Calif., March 01, 2018 (GLOBE NEWSWIRE) -- MannKind Corporation(Nasdaq:MNKD), focused on the development and commercialization of inhaled therapeutic products for patients with diseases such as diabetes and pulmonary arterial hypertension, today announced that it will initiate enrollment of patients in a Phase 1 clinical study of Treprostinil Technosphere (TreT) under an Investigational New Drug (IND) application filed with the Food and Drug Administration (FDA). TreT is proposed as a drug-device combination product for the treatment of patients with pulmonary arterial hypertension (PAH), utilizing a small, portable, breath-powered inhaler that is intended to simplify drug dosing. 

“We are excited to initiate enrollment of our Phase 1 clinical study and to extend the potential application of the Technosphere platform for unmet patient needs in a serious chronic disease such as PAH,” said Dr. David Kendall, Chief Medical Officer of MannKind. “We believe this study will allow for rapid evaluation of treprostonil dosing and therapeutic use in pulmonary arterial hypertension.  If successful, this Phase 1 study will lead to registration studies in 2019.”

The primary objective of the Phase 1 clinical study is to investigate the safety, tolerability, and pharmacokinetics of TreT in healthy volunteers after dosing by oral inhalation.  Secondary endpoints include the evaluation of systemic exposure and pharmacokinetics of TreT, including dose proportionality.

About Pulmonary Arterial Hypertension

Pulmonary Arterial Hypertension (PAH) is a rare, chronic, progressive, and ultimately fatal disease.  It is caused by the hardening and narrowing of the pulmonary arteries, which results in abnormally high blood pressure in these arteries, and leads, with time, to heart failure.  The symptoms of PAH include shortness of breath, dizziness and fatigue, which grow more severe as the disease progresses.  Patients with PAH have severe restrictions on their exercise capacity, reduced quality of life, and a shorter life expectancy.  There is no cure for PAH; currently available treatments manage the symptoms only.
