Olutasidenib Combined With Co-targeted Therapy in Relapsed or Refractory IDH1-mutated Myeloid Malignancies Harboring Activated Signaling Pathway Mutations
brief summary
To learn about the safety and tolerability of study drug combinations in patients with relapsed/refractory, IDH1-mutated myeloid malignancies with a co-signaling mutation.
detailed description
Primary Objectives
1. To determine the safety and tolerability of olutasidenib in combination with cladribine + LDAC ± venetoclax (Arm 1), gilteritinib ± venetoclax (Arm 2), and ruxolitinib (Arm 3) for patients with relapsed/refractory IDH1-mutated myeloid malignancies with a co-signaling mutation. 2. To quantify the composite complete remission rate (CRc; CR + CRh + CRi) in patients with relapsed/refractory IDH1-mutated myeloid malignancies with a co-signaling mutation treated with olutasidenib in combination with cladribine + LDAC ± venetoclax (Arm 1), gilteritinib ± venetoclax (Arm 2), and ruxolitinib (Arm3).
Secondary Objectives
1. To determine overall survival (OS), event free survival (EFS), and duration of response (DOR) with olutasidenib in combination with a co-targeting chemotherapeutic agent. 2. To determine the overall response rate (ORR; CR + CRh + CRi + MLFS + PR) of olutasidenib in combination with a co-targeting chemotherapeutic agent. 3. To evaluate occurrence of measurable residual disease (MRD) negative status by multiparameter flow cytometry and molecular evaluation by polymerase chain reaction (PCR) and next generation sequencing (NGS)-based assays (e.g. IDH1 and FLT3 if applicable). 4. To characterize the pharmacokinetic (PK) profiles of olutasidenib and venetoclax in plasma samples.
