Aironite Fails to Meet Primary Endpoint in the Indie Phase 2 Clinical Study Conducted by the Heart Failure Clinical Research Network

Savara to Discontinue Support of Aironite Development

AUSTIN, TX -- (Marketwired) -- 03/11/18 -- Savara Inc. (NASDAQ: SVRA), an orphan lung disease company, today announced results from the INDIE study of Aironite (sodium nitrite inhalation solution) evaluating the use of inhaled inorganic nitrite for symptom relief in patients with heart failure with preserved ejection fraction (HFpEF). The study did not meet its primary endpoint of improvement in peak exercise capacity assessed by cardiopulmonary exercise testing (CPET), or its secondary endpoints. The topline results were presented at the American College of Cardiology 67th Annual Scientific Sessions & Expo by Barry A. Borlaug, M.D., FACC, Chair for Research, Division of Circulatory Failure, Department of Cardiovascular Medicine, Mayo Clinic and principal investigator for the study. The study was sponsored by Duke Clinical Research Institute as the Coordinating Center for the Heart Failure Clinical Research Network and was conducted primarily with grant funding from the National Heart, Lung, and Blood Institute.

"We would like to thank Dr. Borlaug, the Duke Clinical Research Institute, as well as the Heart Failure Clinical Research Network for their tireless efforts in conducting the study," said Rob Neville, chief executive officer of Savara. "These results were obviously disappointing, but we hope the study will nevertheless serve to increase the understanding of the disease mechanisms in HFpEF, and perhaps help develop other treatment concepts for this difficult clinical condition. Savara's core business focusing on the treatment of orphan lung diseases is unaffected by the results in the INDIE study, and will remain the main value driver of the company."

Aironite is an investigational product that was added to Savara's pipeline as part of Savara's acquisition of Mast Therapeutics in April 2017, and the INDIE study was one of two investigator sponsored Aironite studies in patients with HFpEF initiated prior to the merger. Following the negative outcome of the INDIE study, Savara does not plan to support any new development of Aironite.

About the INDIE Study

The Inorganic Nitrite Delivery to Improve Exercise Capacity in HFpEF (INDIE-HFpEF) study was a multicenter, randomized, double-blind, placebo-controlled, crossover study to evaluate the effect of Aironite on peak exercise capacity as assessed by CPET. One hundred five patients with a diagnosis of HFpEF were enrolled across 17 clinical centers in the United States. The primary endpoint was peak oxygen consumption (VO2) after four weeks of treatment with Aironite or placebo as assessed by CPET performed at peak drug levels. Secondary objectives included (i) submaximal activity tolerance chronically, (ii) quality of life, (iii) chronic filling pressures as assessed by echocardiography and natriuretic peptide levels, (iv) ventilatory efficiency at maximal exercise, and (v) submaximal exercise capacity at peak drug levels; as well as evaluation of the safety and tolerability of Aironite.
