Brief summary

This is a multi-center open-label Phase I/II study investigating orally administered HDM201 in combination with chemotherapy in two populations: subjects with first line AML or subjects with relapsed/refractory AML. This study is conducted in three parts: dose escalation, dose expansion and DDI study.

Detailed description

This is a Phase 1 / 2 study. No patients were screened / enrolled. There are no data collected. There will be no CSR.

Intervention model description

3 parts - two different populations Part 1 - escalation - parallel dose escalation in 1L AML subjects and in R/R subjects (up to 8 dose cohorts per arm. Part 2 - expansion - parallel expansion in 3 cohorts of 1L AML, and 1 cohort of R/R AML after recommended dose of expansion was determined. Part 3 - DDI - parallel enrollment or R/R AML subjects into 2 DDI Cohorts (one with CYP3A4 inhibitor, one with CYP3A4 substrate).
