Pulmatrix Announces Positive Top-Line Data Evaluating PUR1800 in Patients with Stable COPD

LEXINGTON, Mass., March 21, 2022 /PRNewswire/ -- Pulmatrix, Inc. (NASDAQ: PULM), a clinical-stage biopharmaceutical company developing innovative inhaled therapies to address serious pulmonary and non-pulmonary disease using its patented iSPERSE™ technology, today announced positive top-line results of its recently completed Phase 1b clinical study of PUR1800, a narrow-spectrum kinase inhibitor (NSKI) administered as a dry powder for inhalation with iSPERSE^™  for evaluation in patients with stable Chronic Obstructive Pulmonary Disease (COPD). PUR1800 is being developed to treat Acute Exacerbations in Chronic Obstructive Pulmonary Disease (AECOPD). Initial safety and pharmacokinetics (PK) were evaluated in patients with stable COPD.

The Phase 1b trial, performed at the Medicines Evaluation Unit in Manchester, UK, was designed as a randomized, double-blind, placebo-controlled, 3-way crossover study to assess the safety, tolerability, and PK of repeated once-daily doses of PUR1800 or placebo for 14 days, in adult patients with stable COPD.

A total of 18 subjects were enrolled. Safety and tolerability as well as systemic PK were evaluated. PUR1800 was well-tolerated and there were no observed safety signals.  The preliminary PK data indicate that PUR1800 results in low and consistent systemic exposure when administered via oral inhalation.  

Margaret Wasilewski, M.D., Chief Medical Officer Pulmatrix, commented, "We are very encouraged by the safety and preliminary pharmacokinetic results in this study. We will continue to evaluate the complete datasets and expect to submit study results at a relevant medical conference later this year."

Ted Raad, Chief Executive Officer of Pulmatrix commented, "This topline data, along with the results from chronic toxicology studies, support the continued development of PUR1800 for the treatment of AECOPD and other inflammatory respiratory disease. The Phase 1b results are an important step towards advancing PUR1800 into Phase 2 studies and we believe that PUR1800's comprehensive data set will facilitate productive discussions with investors and potential partners."

About AECOPD
There are 18 million moderate-to-severe cases of Acute Exacerbations in Chronic Obstructive Pulmonary Disease (AECOPD) in the U.S. each year. Acute exacerbations of COPD are sudden onset increases in symptoms, including increased dyspnea, sputum purulence and volume, and wheezing, coughing, and shortness of breath that require medical intervention and can lead to hospitalization. The occurrence of an exacerbation greatly increases the likelihood of a further exacerbation within the following 6 months and creates a significant financial burden to healthcare systems.
