KRT-232 and TKI Study in Chronic Myeloid Leukemia
- Conditions
- Chronic Myeloid Leukemia
- Interventions
- Registration Number
- NCT04835584
- Lead Sponsor
- Kartos Therapeutics, Inc.
- Brief Summary
This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, for the treatment of patients with Ph+ Chronic Myeloid Leukemia (CML) who have relapsed or are refractory or intolerant to a Tyrosine Kinase Inhibitor (TKI).
This study is a global, open label Phase 1b/2 to determine the efficacy and safety of KRT-232 in patients with chronic phase CML (CML-CP) and accelerated phase (CML-AP) who have failed TKI treatments.

- Primary Outcome Measures
Name Time Method Part 1: Maximum tolerated dose (MTD)/maximum administered dose (MAD) of KRT-232 28 Days DLTs will be used to establish the MTD/MAD of KRT-232 in combination with dasatinib or nilotinib
Part 2, Arm A and B: Major molecular response (MMR) rate 6 months The proportion of subjects who achieved complete cytogenetic response (CCyR) or partial cytogenetic response (PCyR) according to modified ELN criteria
Part 2, Arm C: Major hematological response (MaHR) rate 6 months The proportion of subjects who achieved MaHR according to modified ELN criteria
- Secondary Outcome Measures
Name Time Method CCyR rate 12 months The proportion of subjects who achieved CCyR or PCyR according to modified ELN criteria in Arms A and B
MCyR rate 47 months The proportion of subjects who achieved CCyR or PCyR according to modified ELN criteria in Arm C
Duration of response 47 months DOR (Kaplan-Meier estimate) defined as the time from first observation of response to progression/relapse or death, whichever comes first
Rate of complete hematologic response (CHR) 47 months The proportion of subjects who achieve a CHR according to modified ELN criteria in Arms A and B
Progression-free survival (PFS) in each Arm 47 months PFS is defined as the time from the first treatment dose date to progression/relapse or death, whichever comes first
Overall survival (OS) in each Arm 47 months OS is defined as the time from the first treatment dose date to death from any cause
