Brief Summary:
This will be a multicenter Phase II open-label study of asciminib in CML-CP patients who have been previously treated with one prior ATP- binding site TKI with discontinuation due to treatment failure, warning or intolerance. (2L patient cohort). In addition, newly diagnosed CML-CP patients who may have received up to 4 weeks of prior TKI are included in a separate 1L patient cohort.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Chronic Myelogenous Leukemia - Chronic Phase | Drug: asciminib | Phase 2 |
This trial consists of three periods: screening and baseline for up to 28 days, active treatment for up to 104 weeks and a safety follow up period for 30 days.
Ninety-two (92) 2L patients with CML-CP without T315I mutation who had 1 prior ATP-binding site TKI discontinued due to treatment failure, warning or intolerance will be considered for the current study. Patients will be tested at screening for the T315I mutation and excluded if the mutation is found.
To gain additional insights into the effect of asciminib in the 1L setting, an additional cohort of newly diagnosed CML-CP patients will be enrolled in the study. Based on the number of participating sites, it is approximated that between 60 and 90 patients could be enrolled. Enrollment of the 1L cohort will be stopped when a maximum of 90 patients have been enrolled or when approximately 60 patients have been enrolled and the 2L cohort is fully recruited, whichever comes first.
Informed consent will be obtained before any procedures are performed for the study including eligibility assessments.
All eligible patients will be initially treated with asciminib at 80 mg QD. At 6 months of study treatment, patients who have achieved BCR-ABL1IS ≤1% will continue on the same dose whereas those who have not will increase dose to 200mg QD.
At 12 months of study treatment, patients will be evaluated for the primary endpoint of the study (MMR at 12 month in 2L patient cohort) and will pursue one of the following:
- Continue on the current dose of asciminib if MMR is achieved
- Increase dose to 200 mg QD if on 80 mg QD dosing and MMR is not achieved
- Increase dose to 200 mg BID if on 200 mg QD dosing and MMR is not achieved
- Take the patient off the study and switch to Investigator's agent of choice if MMR is not achieved and it is in the interest of the patient based on investigator's clinical judgment of prospect treatment benefit.

The rate of MR4.5 where MR4.5 is defined as a ≥ 4.5 log reduction in BCR-ABL1 transcripts compared to the standardized baseline equivalent to ≤ 0.0032% BCR-ABL1/ABL % by international scale as measured by real time Polymerase Chain Reaction (PCR).

- MMR Rate - All scheduled time points [ Time Frame: Baseline up to 3, 6, 18, and 24 months ]Percentage of participants who achieve MMR at or before the specified visit, i.e., if a patient achieves an MMR but then loses it before or at the visit, h/she will still be considered as achieving MMR by that time point.
- Time to MMR [ Time Frame: Baseline up to 24 months ]Time to MMR is defined and calculated as date of first documented MMR - start date of study treatment +1 day.
- Duration of MMR [ Time Frame: Baseline up to 24 months ]Duration of MMR is defined as the time from the date of first documented MMR to the earliest date of loss of MMR, progression to Accelerated Phase (AP) or Blast Crisis (BC), or CML-related death.
- Time to Treatment Failure (TTF) [ Time Frame: Baseline up to 24 months ]Time to treatment failure (TTF) is defined as the time from date of randomization to an event of treatment failure.
- Progression Free Survival (PFS) [ Time Frame: Baseline up to 24 months ]Time from the first dose of study treatment to the earliest occurrence of documented progression to Accelerated Phase (AP) or Blast Crisis (BC) or the date of death from any cause, before the end of the treatment phase.
- Overall Survival (OS) [ Time Frame: Baseline up to 24 months. ]Time from the first dose of study treatment to death due to any cause during the study.
- MR2 Rate - All scheduled time points [ Time Frame: Baseline up to 3, 6, 12, 18, and 24 months ]Percentage of participants who achieve MR2 (defined as a ≥ 2 log reduction in BCR-ABL1 transcripts) at or before the specified visit, i.e., if a patient achieves an MMR but then loses it before or at the visit, h/she will still be considered as achieving MR2 by that time point.
- MR4 Rate - All scheduled time points [ Time Frame: Baseline up to 3, 6, 12, 18, and 24 months ]Percentage of participants who achieve MR4 (defined as a ≥ 4 log reduction in BCR-ABL1 transcripts) at or before the specified visit, i.e., if a patient achieves an MMR but then loses it before or at the visit, h/she will still be considered as achieving MR4 by that time point.
- MR4.5 Rate - All scheduled time points [ Time Frame: Baseline up to 3, 6, 12, and 18 ]Percentage of participants who achieve MR4.5 (defined as a ≥ 4.5 log reduction in BCR-ABL1 transcripts) at or before the specified visit, i.e., if a patient achieves an MMR but then loses it before or at the visit, h/she will still be considered as achieving MR4.5 by that time point.
Other Outcome Measures:
- To investigate MR2, MR4, MR4.5 rate at visit [ Time Frame: Baseline up to 24 months ]MR2, MR4 and MR4.5 at all scheduled data collection time points except for MR4.5 at 24 month
