IRON Disc Medicine Inc

Disc Medicine, Inc. (NASDAQ:IRON), a clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of novel treatments for patients suffering from serious hematologic diseases, today announced that the United States Food and Drug Administration (FDA) has granted Fast Track Designation to DISC-0974 for the treatment of patients with non-dialysis dependent chronic kidney disease (NDD-CKD) and anemia.

“Receiving Fast Track designation highlights the unmet need for the millions of NDD-CKD patients with anemia, as well as the potential of DISC-0974 to address this need,” said John Quisel, J.D., Ph.D., President and Chief Executive Officer of Disc. “We believe DISC-0974 could be a transformative therapy for these patients and are excited to share additional results from our ongoing Phase 1b/2 study in NDD-CKD patients with anemia this year.”

Fast Track is a process designed by the FDA to facilitate the development and expedite the review of investigational drugs intended to treat serious conditions and for which nonclinical or clinical data demonstrate the potential to address unmet medical need. A therapeutic candidate that receives Fast Track designation may be eligible for more frequent interactions with the FDA to discuss the candidate’s development plan. Therapeutic candidates with Fast Track designation may also be eligible for priority review and accelerated approval if supported by clinical data.

About DISC-0974

DISC-0974 is an investigational monoclonal antibody (mAb) targeting a BMP-signaling co-receptor called hemojuvelin (HJV) and is designed to suppress hepcidin production and increase serum iron levels in patients suffering from anemia of inflammation. DISC-0974 was in-licensed by Disc from AbbVie in 2019. Anemia of inflammation arises from abnormally elevated hepcidin and affects millions of patients in the US across numerous diseases such as chronic kidney disease, myelofibrosis, cancer, autoimmune diseases, and other conditions with an inflammatory component. Disc has established clinical proof-of-mechanism of DISC-0974 in a Phase 1 trial of healthy volunteers and has ongoing clinical studies of DISC-0974 in patients with myelofibrosis and anemia and also in patients with NDD-CKD and anemia.

DISC-0974 is an investigational agent and is not approved for use as a therapy in any jurisdiction worldwide.

About Anemia of Chronic Kidney Disease (CKD)

Chronic kidney disease (CKD) is a global, widespread disease characterized by progressive loss of kidney function and may lead to end-stage renal disease (ESRD) or kidney failure. CKD affects over 37 million patients in the United States and an estimated 700 million patients worldwide. Anemia is a serious and frequent complication of CKD, as patients are unable to produce sufficient red blood cells and hemoglobin. It affects approximately 5-6 million patients in the U.S. alone, may result in fatigue, shortness of breath, and reduced physical and cognitive function, and can be associated with a higher risk of mortality, hospitalization and other complications. Elevated hepcidin is a primary cause of anemia in CKD patients and prevents erythropoiesis by depriving developing red blood cells of iron. Hepcidin accumulates at high levels in CKD patients because its production is stimulated by inflammation and its clearance is reduced as a consequence of impaired renal function. The majority of CKD patients do not receive any treatment for their anemia due to the complexity of outpatient administration and potential safety concerns related to the current treatments. In severe cases, patients may receive blood transfusions, but transfusions require significant healthcare utilization, incur safety risks and increase the potential for immune sensitization which precludes eligibility for kidney transplantation.
