Pulmatrix Wins $14M to Back Drug For Cystic Fibrosis And Other Lung Ailments

Xconomy Boston — 

Pulmatrix, the Lexington, MA-based company with an unusual strategy for fighting diseases of the lungs, is announcing today that it has secured $14 million in a Series B1 venture round, bringing the total amount raised by the company to $60 million.

PUR118 is a dry powder that patients can inhale. Pulmatrix initially developed it as a liquid formulation, called PUR003, which patients had to inhale via a somewhat bulky machine called a nebulizer.
