Pulmatrix Announces FDA Acceptance of IND Application for PUR3100 to Treat Acute Migraine

Pulmatrix received a study may proceed letter for a Phase 2 Study to Evaluate PUR3100, an orally inhaled dry powder formulation of dihydroergotamine ("DHE") in the treatment of acute migraine

BEDFORD, Mass., Sept. 19, 2023 /PRNewswire/ -- Pulmatrix, Inc. ("Pulmatrix" or the "Company") (NASDAQ: PULM), a clinical-stage biopharmaceutical company developing innovative inhaled therapies to address serious pulmonary and central nervous system diseases, today announced the U.S. Food and Drug Administration ("FDA") has accepted the PUR3100 investigational new drug ("IND") application and the Company has received a study may proceed letter for a Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Single Event Study to Evaluate the Safety, Tolerability, and Efficacy of PUR3100 (Dihydroergotamine Mesylate Inhalation Powder) in the Acute Treatment of Migraine. The PUR3100 formulation uses Pulmatrix's novel, proprietary dry powder delivery technology, iSPERSE™ to deliver DHE via oral inhalation using a dry powder inhaler.

Dr. Margaret Wasilewski, Chief Medical Officer of Pulmatrix noted, "We are pleased with the PUR3100 IND acceptance and receipt of the study may proceed letter for the Phase 2, proof of concept study. We are looking forward to building on the positive safety and pharmacokinetic data established in our phase 1 study."

Ted Raad, Chief Executive Officer of Pulmatrix, commented, "We believe that PUR3100 has the potential to be differentiated from other approved acute migraine therapies currently available on the market, given the convenience of self-administration and the potential for rapid pain relief and improved DHE tolerability. The completed Phase 1 study demonstrated optimal pharmacokinetics and improved tolerability of PUR3100 compared to IV DHE.  We are currently pursuing options to advance PUR3100 into a Phase 2 clinical trial to investigate PUR3100 efficacy, safety, tolerability in treating acute migraine subjects."

About PUR3100
PUR3100 is an orally inhaled formulation of dihydroergotamine (DHE) engineered with iSPERSE™ for the treatment of acute migraine. The Phase 1 PUR3100 trial results were presented at the 65th Annual Meeting of the American Headache society in June 2023.  Over 38 million patients suffer from migraine in the United States and there is currently no orally inhaled DHE treatment option for patients.

About iSPERSE™ Technology
Our innovative particle engineering technology creates dry powder, which solves limitations of conventional inhaled technologies and expands the universe of inhalable drug therapies. iSPERSE is a proprietary technology that allows a broad range of drugs to be formulated as small, dense, and dispersible particles for highly efficient drug delivery and deep penetration into the lungs. iSPERSE can efficiently deliver small molecules, drug combinations, peptides, proteins, and nucleic acids via the respiratory system for the treatment of both respiratory and non-respiratory diseases.
