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.

Condition or disease Intervention/treatment Phase
Chronic Myeloid Leukemia Drug: ELVN-001 Phase 1

Detailed Description:
This first-in-human trial with ELVN-001 is a dose escalation study whose primary purpose is to identify the recommended dose for expansion RDE of single agent ELVN-001 in chronic phase or accelerated phase CML with and 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 RDE safety profile, PK and preliminary evidence of anti-CML activity will be used to inform future development 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 tolerable or benefit from available TKIs.

Primary Outcome Measures :
  1. Phase 1a: Incidence of dose limiting toxicities [ Time Frame: 28 days ]
    DLTs will be used to support that the recommended doses for expansion are </= MTD

  2. 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

  3. 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

  4. 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

  5. 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

  6. 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

  7. 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


Secondary Outcome Measures :
  1. Phase 1a and 1b: area under the curve [ Time Frame: 6 months ]
    PK parameter based on measurement of drug concentration in blood over time

  2. Phase 1a and 1b: maximum concentration [ Time Frame: 6 months ]
    PK parameter based on measurement of drug concentration in blood

  3. 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

  4. 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.

  5. Phase 1a and 1b: molecular response [ Time Frame: up to 3 years ]
    measured by quantitative polymerase chain reaction of BCR-ABL transcript levels

  6. Phase 1b: duration of molecular response [ Time Frame: up 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

  7. Phase 1b: frequency of complete cytogenetic remission (CCyR) [ Time Frame: up to 3 years ]
    The proportion of patients who achieve CCyR by serum BCR-ABL1 transcript level who are not in CHR at baseline

  8. Phase 1b: Rate of complete hematologic response (CHR) [ Time Frame: up to 3 years ]
    The proportion of patients who achieve a CHR who are not in CHR at baseline
