The U.S. FDA named the first nine recipients of the recently unveiled commissioner’s national priority voucher (CNPV) program aimed at addressing unmet public health needs by shortening regulatory review times to as little as one to two months. For one of those firms, Disc Medicine Inc., which submitted an NDA for bitopertin for rare genetic disorder erythropoietic protoporphyria in September, that could mean a potential approval before the end of 2025.
Disc Medicine Inc. found itself after an end-of-phase II meeting with the U.S. FDA in what Wainwright analyst Douglas Tsao called a “best-case scenario” regarding the path forward for bitopertin in erythropoietic protoporphyria (EPP).
Disc Medicine Inc. CEO John Quisel said that top-line phase II findings from the study called Aurora with bitopertin in erythropoietic protoporphyria are “hard for us to interpret. This package of data is something that we’re going to have to sort through,” and the Watertown, Mass.-based firm expects to talk with the U.S. FDA about next steps in the second half of this year.
Disc Medicine Inc.’s positive phase II data from an ongoing, open-label trial called Beacon with oral bitopertin in erythropoietic protoporphyria (EPP) and X-linked protoporphyria (XLP) whetted investor appetite for the results of the other mid-stage Disc experiment known as Aurora with the compound, due early next year.
Mabwell Therapeutics Inc., a wholly owned subsidiary of Mabwell (Shanghai) Bioscience Co. Ltd., has entered into a license agreement with Disc Medicine Inc. for 9MW3011 (MWTX-001, MWTX-002 & MWTX-003) for hematologic diseases.
The most common cause of anemia in chronically ill hospitalized patients is due to inflammatory anemia (IA) that is caused indirectly by diseases such as autoimmune, cancer, chronic kidney disease, congestive heart failure, or pulmonary disease. The precise and common etiology of these diseases involves hypercytokinemia that leads to excessive increases in hepcidin, a master regulator of iron homeostasis that blocks intestinal iron absorption when levels are too persistently high.
As it moves into phase II testing with the lead candidate from its hematologic pipeline, privately held Disc Medicine Inc. is also moving to the public markets via a reverse merger agreement with struggling biotech Gemini Therapeutics Inc. Concurrent with a $53.5 million financing from investors, the deal is expected to provide Disc with a cash runway into 2025.
Disc Medicine Inc. closed a $90 million series B round to move its two lead assets into clinical trials in patients next year. Bitopertin, an oral inhibitor of glycine transporter 1 (GlyT1), is entering a phase II trial in patients with erythropoietic porphyrias (EPPs), a set of rare genetic disorders caused by mutations that disrupt heme synthesis. Disc-0974, an antibody directed against hemojuvelin, will enter a phase II trial in myelofibrosis patients with transfusion-dependent anemia. The molecule, which Disc Medicine in-licensed from North Chicago-based Abbvie Inc., is currently undergoing a phase I trial in healthy volunteers.
Brian MacDonald's pursuit of an approved hepcidin therapy at Merganser Biotech Inc. didn't quite pan out, but that didn't stop him from taking up Atlas Venture's offer to try it once again on a different tack.
