Summary
Brief summary (as posted)
The goal of this study is to assess the safety, tolerability, anti-tumor activity (efficacy), pharmacokinetics (PK), and pharmacodynamics (PD) of the agent RVU120 when administered to adult patients with relapsed or refractory acute myeloid leukemia (AML) or relapsed or progressing high-risk myelodysplastic syndrome (HR-MDS) and who have no alternative therapies available. The study consists of two parts. Part 1 will assess the safety and tolerability of the dosages given and the level of anti-tumor activity or clinical response. Based on the results from part 1 the study will continue to enrol patient into Part 2 which will continue to evaluate safety and tolerability and anti-tumor activity in a larger number of patients.
