A Phase 1b Study of DISC-0974, an Anti-Hemojuvelin Antibody, in Patients with Myelofibrosis and Anemia
At the time of data cut, 34 participants were enrolled at 5 dose levels: 14 mg (n=1), 28 mg (n=7), 50 mg (n=12), 75 mg (n=8), and 100 mg (n=6). Treatment with DISC-0974 resulted in meaningful and sustained hepcidin reductions with mean change from baseline (mean 88.2 ng/mL; range [8.7, 374.7]) reaching over 80% across treated participants. This corresponded to iron mobilization at all dose levels.
