WATERTOWN, Mass., Oct. 25, 2024 (GLOBE NEWSWIRE) -- 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 presented positive additional data from an ongoing Phase 1b study of DISC-0974 in patients with non-dialysis-dependent chronic kidney disease (NDD-CKD) and anemia, including results from the 40 mg and 60 mg single ascending dose (SAD) cohorts. The data presented at the 2024 American Society of Nephrology (ASN) Kidney Week in San Diego, CA demonstrated that a single dose of DISC-0974 results in sustained suppression of hepcidin and mobilization of iron, and increased erythropoiesis and levels of hemoglobin in NDD-CKD patients with anemia.

“We are pleased to present these updated results, which provide the first clinical evidence in CKD anemia that reducing hepcidin through hemojuvelin translates into increased erythropoiesis and hemoglobin. Importantly, we were able to observe activity following only a single dose of DISC-0974, which will enable us to efficiently explore dose regimens in the multiple-dose portion of the Phase 1b study,” said John Quisel, JD, PhD, President and Chief Executive Officer of Disc Medicine. “We have now shown that DISC-0974 can improve anemia in the settings of both myelofibrosis and chronic kidney disease. This speaks to the much broader potential for DISC-0974 to address anemia caused by a range of inflammatory and chronic diseases, each of which are associated with elevated hepcidin, and we look forward to providing our plans to access these indications.”

In the SAD portion of this study, participants with Stage 2-5 NDD-CKD were given a single dose of placebo (n=7) or DISC-0974 subcutaneously (SC) at 28 mg (n=9), 40 mg (n=6), or 60 mg (n=6). Dose escalation is ongoing in the SAD. This interim data set demonstrated:

  • Substantial, durable, dose-dependent reduction in hepcidin from baseline compared to placebo across dose levels, with median reduction greater than 75% from baseline at highest dose level

  • Meaningful and sustained increase in transferrin saturation from baseline compared to placebo across dose levels, with median increase up to 3x from baseline at highest dose level

  • Early and sustained increase in mean reticulocyte hemoglobin from baseline across all dose groups through Day 22 and beyond

    • Maximal mean values through Day 22 of +1.14 pg at 28 mg, +1.49 pg at 40 mg, and +1.53 pg at 60 mg, compared with +0.21 pg on placebo

  • Increase in mean hemoglobin from baseline across dose groups over the study period

    • Change greater than placebo: +0.35 g/dL at 28 mg, +0.54 g/dL at 40 mg, and +0.55 g/dL at 60 mg

  • Mean maximal increase in hemoglobin of +0.8 g/dL at 40 mg and +0.7 g/dL at 60 mg compared with +0.2 g/dL on placebo

    • Maximal observed individual increase in hemoglobin up to +0.95 g/dL at 28 mg, +1.5 g/dL at 40 mg, and +1.8 g/dL at 60 mg

  • DISC-0974 demonstrated acceptable safety and tolerability at all evaluated dose levels

    • The majority of adverse events were deemed not related to DISC-0974 and all adverse events assessed as treatment-related were Grade 1 or 2
