Introduced last year as a pilot program, the U.S. FDA Commissioner’s National Priority Voucher (CNPV) could be here to stay – at least for the duration of Marty Makary’s tenure as FDA commissioner. Since the FDA unveiled the CNPV last June, it has welcomed 18 products from 16 companies into the “game-changer” program for patients, as Makary described it. The goal is to provide an “ultrafast review pathway,” one to two months instead of the standard 10 to 12 months, for drugs and biologics of strategic national importance while maintaining the FDA’s scientific and regulatory standards, according to the agency.
At the current pace of innovation in the U.S. rare disease space, developing and approving therapies for just half of the 10,000-plus known rare diseases would take more than 160 years, Bradley Campbell, president and CEO of Amicus Therapeutics Inc., recently told the Senate Committee on Aging.
Though it’s largely viewed by analysts as a simple delay rather than a setback, Disc Medicine Inc.’s unexpected complete response letter (CRL) for bitopertin in the rare genetic disorder erythropoietic protoporphyria (EPP) raises more questions regarding consistency and stability at the U.S. FDA.
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.
