BACKGROUND: Hepcidin plays a central role in iron homeostasis and erythropoiesis.
Neutralizing hepcidin with a monoclonal antibody (mAb) may prevent ferroportin
internalization, restore iron efflux from cells, and allow transferrin-mediated
iron transport to the bone marrow. This multicenter, phase 1 study evaluated the
safety, pharmacokinetics (PK), pharmacodynamics (PD), and efficacy of a fully
humanized mAb (LY2787106) with high affinity for hepcidin in cancer patients with
anemia. METHODS: Thirty-three patients with hepcidin levels ?5 ng/mL received
LY2787106 either every 3 weeks (19 patients, dose range 0.3-10 mg/kg) (part A) or
weekly (14 patients, dose 10 mg/kg) (part B). LY2787106 PK/PD markers of iron and
hematology biology were measured. RESULTS: LY2787106 clearance (32 mL/h) and
volume of distribution (7.7 L) were independent of dose and time, leading to a
dose-proportional increase in concentration with dose. Consistent dose-dependent
increases in serum iron, and transferrin saturation were seen at the 3 and
10 mg/kg dose levels, typically peaking within 24 h after LY2787106
administration and returning to baseline by day 8. CONCLUSIONS: Our findings
indicate that LY2787106 was well tolerated in cancer patients with anemia and
that targeting the hepcidin-ferroportin pathway by neutralizing hepcidin resulted
in transient iron mobilization, thus supporting the role of hepcidin in iron
regulation. TRIAL REGISTRATION: ClinicalTrial.gov, NCT01340976.
