简要总结
The objective of this study to evaluate the safety, tolerability, pharmacokinetic profile, and preliminary efficacy of BL-M11D1 in patients with relapsed/refractory acute myeloid leukemia.
详细描述
BL-M11D1-HM-101 is a multi-center, Phase 1 study to evaluate the safety, tolerability, pharmacokinetic profile, and preliminary efficacy of BL-M11D1 in patients with relapsed/refractory acute myeloid leukemia.
This study will be conducted in two parts (dose escalation, and dose finding). Cohort A will be dosed on Days 1, 8,15 of a continuous 28-day treatment cycle. The cohort has different dose groups. Cohort B will be dosed on Days 1, 4, 7 or 8 of a continuous 28-day treatment cycle. The cohorts have different dose groups.
