A Phase 1a/1b Study of ELVN-001 for the Treatment Chronic Myeloid Leukemia

Phase 1

Conditions
Chronic Myeloid Leukemia
Chronic Phase Chronic Myeloid Leukemia, BCR-ABL1 Positive
Cml
Interventions
Registration Number
NCT05304377
Lead Sponsor
Enliven Therapeutics
Brief Summary

The purpose of this study is to evaluate the safety, tolerability and determine the recommended dose for further clinical evaluation of ELVN-001 in patients with chronic myeloid leukemia with and without T315I mutations in patients who are relapsed, refractory or intolerant to TKIs.

Detailed Description

This first-in-human trial with ELVN-001 is a dose escalation study with the primary purpose to identify the recommended dose(s) for expansion (RDEs) of single agent ELVN-001 in chronic phase CML with or without T315I mutations. The safety, tolerability and pharmacokinetic profile of ELVN-001 will be assessed together with an evaluation of changes in BCR-ABL1 transcript. An understanding of the safety profile, PK and preliminary evidence of anti-CML activity will be used to inform future development of ELVN-001 in adults with CML. By virtue of its predicted pharmacological profile ELVN-001 has the potential to be tolerable and achieve a deep molecular response in patients with CML with or without T315I mutations who do not tolerate or benefit from available TKIs.

Primary Outcome Measures
NameTimeMethod
Phase 1b: Incidence of adverse eventsup to 3 years

Adverse events will be used to support that the dose(s) evaluated in expansion is tolerable

Phase 1a: Incidence of dose limiting toxicities28 days

DLTs will be used to support that the recommended doses for expansion are \</= MTD

Phase 1a: Incidence of adverse events (AEs)up to 28 days

Adverse events will be used to support that the recommended doses for expansion are likely to be tolerable

Phase 1a: Incidence of clinically significant laboratory abnormalitiesup to 28 days

Clinically significant laboratory abnormalities will be used to support that the recommended doses for expansion are likely to be tolerable

Phase 1a: Incidence of clinically significant ECG abnormalitiesup to 28 days

Clinically significant ECG abnormalities will be used to support that the recommended doses for expansion are likely to be tolerable

Phase 1b: Incidence of clinically significant laboratory abnormalitiesup to 3 years

Clinically significant ECG abnormalities will be used to support that the dose(s) evaluated in expansion is tolerable

Phase 1b: Incidence of clinically significant ECG abnormalitiesup to 3 years

Clinically significant ECG abnormalities will be used to support that the recommended dose(s) evaluated in expansion is tolerable

Secondary Outcome Measures
NameTimeMethod
Phase 1a and 1b: area under the curve6 months

PK parameter based on measurement of drug concentration in blood over time

Phase 1a and 1b: maximum concentration6 months

PK parameter based on measurement of drug concentration in blood

Phase 1a and 1b: time of maximum concentration6 months

PK parameter which is the time at which the highest concentration of drug in the blood is measured

Phase 1a and 1b: minimum concentration6 months

PK parameter based on the measurement of the drug concentration that is at the lowest level once steady state has been achieved.

Phase 1a and 1b: Molecular response (MR)up to 3 years

measured by quantitative polymerase chain reaction of BCR-ABL transcript levels

Phase 1b: Duration of Molecular Responseup to 3 years

Time from first molecular response (as measured by quantitative polymerase chain reaction of BCR-ABL transcript levels) to loss of response or discontinuation of study drug

Phase 1b: Complete Hematologic Response (CHR)up to 3 years

The proportion of patients who achieve a CHR who are not in CHR at baseline
