Pulmatrix Receives Patents Important to its Inhaled Drug Delivery Technology

LEXINGTON, Mass., Dec. 19, 2016 /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 five patents over the last 12 months.

"These new patents are further proof that our iSPERSE™ inhaled drug technology is innovative," said Robert W. Clarke, Ph.D., Chief Executive Officer for Pulmatrix. "These patents give us stronger composition of matter and method of use intellectual property protection as we move forward to develop drugs for COPD, fungal infections, and other diseases." 

Two of the patents (US 9,233,158 and US 9,238,005) extend existing patent coverage in the United States. Two more (JP 5,877,201 and JP 5,964,939) provide similar extensions in Japan.

The fifth patent (US 9,433,576), which was granted on September 6, 2016, broadens the patent protection for Pulmatrix's innovative drug delivery technology and its use to treat a wide variety of diseases.

As the patent explains, delivering drugs directly to the lungs offers numerous advantages. But existing technologies have serious limitations, such as leaving much of the drug stuck in the mouth or throat, causing side effects. "Therefore, there remains a need for the formation of small particle size aerosols that are highly dispersible," the patent says.

Pulmatrix's technology seeks to meet that need. Its dry powder 'flies' easily into the lungs, reducing the amount stuck in the throat. In addition, the technology can deliver much larger doses of drugs—and many more different types of drugs—than existing methods can.

The patent recognizes the advantages of the technology and grants intellectual property protection for many different medical uses of Pulmatrix's technology. As the patent states: "The invention also relates to methods for treating a respiratory disease, such as asthma, airway hyper-responsiveness, seasonal allergic allergy, bronchiectasis, chronic bronchitis, emphysema, chronic obstructive pulmonary disease, cystic fibrosis and the like." 

"As we look to continue to advance our pipeline, these patents will prevent competitors from copying our technology," added Dr. Clarke.
