Transfusion-dependent (TD) high cohort: transfusion independence (Phase 2 only)
From Day 1 to the end of treatment on Day 169

Defined as the absence of packed red blood cell (PRBC) transfusions over any rolling 12-week interval during the treatment period with a minimum hemoglobin (Hgb) of 7 g/dL. Participants meeting this criterion will be considered to have a major response to treatment.

TD low cohort: transfusion independence (Phase 2 only)
From Day 1 to the end of treatment on Day 169

Defined as the absence of PRBC transfusions over any rolling 16-week interval during the treatment period with a minimum Hgb of 7 g/dL. Participants meeting this criterion will be considered to have a major response to treatment.

Non-transfusion-dependent (nTD) cohort: anemia response (Phase 2 only)
From Day 1 to the end of treatment on Day 169

Defined as the composite of the absence of transfusions over any rolling 12-week period and a concomitant mean Hgb increase of ≥1.5 g/dL over baseline. Participants meeting this criterion will be considered to have a major response to treatment.

Frequently asked questions about DISC-0974

What is DISC-0974 used for?

DISC-0974 is an investigational small molecule being developed for anemia associated with chronic kidney disease, inflammatory bowel disease, and myelofibrosis. Disc Medicine is studying it in adults with these conditions who have anemia, including anemia of chronic kidney disease and anemia related to myelofibrosis or myelodysplastic syndrome.

What does DISC-0974 target?

DISC-0974 targets hemojuvelin, also known as HJV. Hemojuvelin is involved in the regulation of hepcidin, a hormone that controls iron availability. By targeting HJV, DISC-0974 is designed to affect iron metabolism and red blood cell production in patients with anemia linked to chronic inflammation or bone marrow disorders.

Who is developing DISC-0974?

DISC-0974 is being developed by Disc Medicine, Inc., which trades under the ticker IRON. The company is running clinical studies of the drug in anemia associated with chronic kidney disease, inflammatory bowel disease, and myelofibrosis or myelodysplastic syndrome.

What phase is DISC-0974 in?

DISC-0974 is in clinical development, with Phase 1 studies completed or ongoing and a Phase 2 study now recruiting. It is investigational and has not been approved by the FDA. The FDA has granted DISC-0974 a Fast Track designation.

What clinical trials is DISC-0974 in?

DISC-0974 has been studied in NCT05745883, a completed Phase 1 trial in chronic kidney disease and anemia, and NCT05320198, a recruiting Phase 1 trial in myelofibrosis or myelodysplastic syndrome and anemia. A Phase 2 trial, NCT07368972, is recruiting participants with inflammatory bowel disease and anemia in the United States.

Is DISC-0974 placebo controlled?

Yes. DISC-0974 trials have used randomized, double-blind, placebo-controlled designs. The studies enroll adults aged 18 years and older and do not include healthy volunteers, focusing instead on patients with anemia related to chronic kidney disease, inflammatory bowel disease, or myelofibrosis.
