Brief summary
The purpose of this study is to assess the safety, tolerability and clinical activity of the combination S64315 with azacitidine in patients with acute myeloid leukaemia.
Interventions
The combination treatment at the planned doses may be preceded by a 2-week Lead-In Dose period of S64315 (fixed dose) administered via intravenous (IV) infusion over at least 2 hours. During the combination treatment period S64315 will be administered according to a dose escalation scheme starting at 50 mg up to 250 mg might be explored. The schedule will be a 21-day cycle with a weekly regimen for S64315 and a daily regimen of azacitidine administered at 75 mg/m² via subcutaneous (SC) injection for 7 days from D1 to D7 of each cycle followed by a rest period of 21 days.
