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

March 31, 2026 updated by: Enliven Therapeutics

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

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • BCR-ABL1 positive CML in chronic phase, with or without T315I mutation.
  • US: The patient has failed or is intolerant to at least one prior second-generation tyrosine kinase inhibitor (TKI) or asciminib. Rest of World: The patient has failed, is intolerant to, or not a candidate for, available therapies known to be active for treatment of their CML (country-specific criteria may vary).
  • ECOG performance status of 0 to 2.
  • Adequate hematologic, hepatic and renal function.
  • Prior bone marrow transplant allowed if ≥ 6 months prior to the first dose of ELVN-001.

Exclusion Criteria:

  • Treatment with anti-cancer or anti-CML therapy within 7 days or 5 half-lives, whichever is longer.
  • History of acute tyrosine kinase inhibitor (TKI)-related pancreatitis within 6 months of study entry. Active chronic pancreatitis, or pancreatic disease due to any cause.
  • QTc >470 ms.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: 28 days
DLTs will be used to support that the recommended doses for expansion are </= MTD
28 days
Phase 1a: Incidence of adverse events (AEs)
Time Frame: up to 28 days
Adverse events will be used to support that the recommended doses for expansion are likely to be tolerable
up to 28 days
Phase 1a: Incidence of clinically significant laboratory abnormalities
Time Frame: up to 28 days
Clinically significant laboratory abnormalities will be used to support that the recommended doses for expansion are likely to be tolerable
up to 28 days
Phase 1a: Incidence of clinically significant ECG abnormalities
Time Frame: up to 28 days
Clinically significant ECG abnormalities will be used to support that the recommended doses for expansion are likely to be tolerable
up to 28 days
Phase 1b: Incidence of clinically significant laboratory abnormalities
Time Frame: up to 3 years
Clinically significant ECG abnormalities will be used to support that the dose(s) evaluated in expansion is tolerable
up to 3 years
Phase 1b: Incidence of clinically significant ECG abnormalities
Time Frame: up to 3 years
Clinically significant ECG abnormalities will be used to support that the recommended dose(s) evaluated in expansion is tolerable
up to 3 years
Phase 1b: Incidence of adverse events
Time Frame: up to 3 years
Adverse events will be used to support that the dose(s) evaluated in expansion is tolerable
up to 3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Phase 1a and 1b: area under the curve
Time Frame: 6 months
PK parameter based on measurement of drug concentration in blood over time
6 months
Phase 1a and 1b: maximum concentration
Time Frame: 6 months
PK parameter based on measurement of drug concentration in blood
6 months
Phase 1a and 1b: time of maximum concentration
Time Frame: 6 months
PK parameter which is the time at which the highest concentration of drug in the blood is measured
6 months
Phase 1a and 1b: minimum concentration
Time Frame: 6 months
PK parameter based on the measurement of the drug concentration that is at the lowest level once steady state has been achieved.
6 months
Phase 1a and 1b: Molecular response (MR)
Time Frame: up to 3 years
measured by quantitative polymerase chain reaction of BCR-ABL transcript levels
up to 3 years
Phase 1b: Duration of Molecular Response
Time Frame: up to 3 years

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
