MannKind also bought a convertible bond from Thirona

WESTLAKE VILLAGE, CALIFORNIA and SAN DIEGO, June 10, 2021 (GLOBE NEWSWIRE) – MannKind Corporation (Nasdaq: MNKD) and Thirona Bio, Inc. announced today that they have completed a transaction to advance the development of a novel compound with potential in multiple indications.

FBM5712 is a novel small molecule inhibitor of ALK-5 kinase (transforming growth factor-β (TGF-β) receptor kinase) that Thirona is developing as a topical product to prevent and / or reduce skin fibrosis. “TGF-β is also implicated in fibrotic lung disease and ALK-5 has been validated as a potential target for idiopathic pulmonary fibrosis,” said Thomas Hofmann, MD, Ph.D., chief scientific officer of MannKind Corporation.

Under the terms of the collaboration agreement, the companies will evaluate the therapeutic potential of Thirona’s topical TGF-β inhibitor for the treatment of pulmonary fibrosis. MannKind will formulate FBM5712 as a dry powder formulation. If initial studies are promising, MannKind can exercise certain rights to seek a full license for the compound for clinical development and commercialization for the treatment of fibrotic lung diseases.

In addition to the collaboration agreement, the companies have entered into a purchase agreement for convertible notes to support Thirona’s Series A financing.

“This collaboration with MannKind gives Thirona the opportunity to expand the development of FBM5712 with a new formulation to include fibrotic lung diseases,” said Dr. Gordon Foulkes, Founder and Chief Executive Officer of Thirona Bio. “We continue to focus on the dermatological uses of this drug – against scleroderma, keloid scars and certain types of cancer – and are now looking forward to investigating lung indications with the experienced MannKind team.”

“We recently announced our goal of bringing one new product from our pipeline to market each year between 2025 and 2030,” said Michael Castagna, PharmD, chief executive officer of MannKind Corporation. “We appreciate the opportunity to evaluate FBM5712 and evaluate its potential in support of our pipeline ambitions.”
