Pulmatrix Receives Key US Patent for its Inhaled Drug for COPD

LEXINGTON, Mass., May 9, 2017 /PRNewswire/ -- Pulmatrix, Inc. (NASDAQ: PULM), a clinical stage biopharmaceutical company developing innovative inhaled therapies to address serious pulmonary diseases, today announced that it has received a key patent in the United States for its lead drug candidate, PUR0200, which is intended to treat chronic obstructive pulmonary diseases (COPD).

"This patent ensures that the product is protected by intellectual property until 2033," said Robert W. Clarke, Ph.D., Chief Executive Officer for Pulmatrix. "It also is further recognition of the potential medical advances offered by our innovative iSPERSEtm technology for delivering drugs to the lungs more efficiently."

The new patent, US 9642798, follows both an earlier patent granted in Japan in 2016 (JP 5877204) for the composition of PUR0200 and several broader patents (such as US 9061352, 9119778, 9233158, 9238005 and 9433576) that provide protection for Pulmatrix's technology platform and its use to treat a wide variety of diseases.

The new patent covers PUR0200, an inhaled drug made by combining Pulmatrix's technology platform with tiotropium bromide. Tiotropium bromide is the active ingredient in Spiriva, a blockbuster inhaled drug with annual global sales of approximately ?3 billion in 2016.

The limitation with current inhaled products is that a significant amount of the drugs get stuck in the mouth or throat, causing side effects and poor delivery efficiency to the intended site of action in the lungs. Pulmatrix has tackled this problem by creating a dry powder that 'flies' more easily into the lungs. Drugs like tiotropium bromide that are incorporated into the iSPERSE powder thus are far more likely to reach their intended target, offering a major medical benefit.

In fact, clinical trials of PUR0200 have shown that the product is up to five times more efficient at delivering the drug to the lungs than are the currently marketed alternatives.

Pulmatrix is now developing PUR0200 in both Europe and the United States, following regulatory pathways that offer quicker approvals and lower costs.

"This new patent is another step forward to bringing PUR0200 to market?and to be able to offer new benefits to patients suffering from COPD," added Dr. Clarke.
