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.
Merck & Co. Inc. is adding to its hematology assets in the takeover of Imago Biosciences Inc. for $36 per share, an arrangement with an equity value of about $1.35 billion. Shares of Imago (NASDAQ:IMGO) took flight as Wall Street learned of the deal, ending the day at $35.59, up $18.19, or 104%. Imago is working on new drugs for myeloproliferative neoplasms and other bone marrow diseases. Lead candidate bomedemstat (IMG-7289), an orally available inhibitor of the epigenetic enzyme lysine-specific demethylase 1 (LSD1), is undergoing phase II trials for the treatment of essential thrombocythemia, myelofibrosis and polycythemia vera, along with other indications.
Protagonist Therapeutics Inc. has disclosed hepcidin mimetic conjugates acting as solute carrier family 40 member 1 (SLC40A1, ferroportin) ligands with extended half-life and stability.
It’s been one thing after another for rusfertide from Protagonist Therapeutics Inc. for the past year. Now the U.S. FDA has told the company it wants to rescind the breakthrough designation, a relatively rare occurrence, based on observed malignancies in a follow-up to September’s clinical hold.
The FDA has approved Pharmaessentia Corp.'s Besremi (ropeginterferon alfa-2b) for the rare blood disorder polycythemia vera, the interferon offering an alternative to JAK inhibitor therapy. PV is a rare, chronic and life-threatening blood cancer caused by a mutation in stem cells in the bone marrow, resulting in overproduction of blood cells. Besremi, which is already approved in Taiwan, Europe and South Korea, is a monopegylated, long-acting interferon, which counteracts the effects of the mutated bone marrow cells and is initially taken fortnightly.
Shares of Protagonist Therapeutics Inc. (NASDAQ:PTGX) fell 62% to $17.53 on Sept. 17 after it reported finding malignant skin tumors in a mouse model test of its most advanced candidate, rusfertide for blood disorders. After the company notified the FDA, the regulator put the program on a clinical hold, leading dosing of patients in all ongoing trials of rusfertide to be halted for now. The development could impact Protagonist's ability to start phase III testing of the candidate in polycythemia vera (PV) early in 2022, as well as efforts to expand its development to a third indication beyond PV and hereditary hemochromatosis (HH) by the end of this year, as it has planned.
