What is the purpose of the study

This is a study to evaluate oral asciminib in patients with CML in chronic phase (CP) who have been previously treated with one prior ATP- binding site tyrosine kinase inhibitor (TKI) with discontinuation due to treatment failure, warning or intolerance  [second line (2L) patient cohort].

This study also gains insights into the effect of asciminib when used in first line (1L) treatment. To this end, newly diagnosed CML-CP patients who may have received a TKI for up to 4 weeks are included in a separate 1L patient cohort.

What will happen during the study

This trial consists of three periods: screening and baseline for up to 28 days, treatment with ascimib for up to 104 weeks and a safety follow up period for 30 days.

Patients with CML-CP without T315I mutation who had received 1 prior ATP-binding site TKI will be considered for inclusion in the 2L patient cohort of this trial.

In addition, newly diagnosed CML-CP patients will be considered for inclusion in a separate 1L patient cohort.

All eligible patients will initially receive asciminib 80 mg once daily. At 6 months of study treatment, patients who have achieved BCR-ABL1IS ≤1% will continue on the same dose whereas those who have not achieved this will increase their dose to 200 mg once daily.

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). They will then:

 

  • continue on the current dose of asciminib if MMR is achieved, or
  • increase dose to 200 mg once daily if they are on 80 mg once daily dosing and have not achieved MMR, or
  • increase dose to 200 mg twice daily if they are on 200 mg once daily dosing and have not achieved MMR, or
  • be taken off the study and switched 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.

Key inclusion criteria

This study includes patients of all sexes who:

  • are aged 18 years or older
  • have chronic myelogenous leukemia in chronic phase (CML-CP), no previous accelerated phase (AP) or blast crisis (BC)
  • have an Eastern Co-Operative Group (ECOG) status of 0, 1 or 2
  • have adequate end organ function within 14 days before the first dose of asciminib treatment.

Further criteria apply. Please discuss these with your doctor or study staff.

Key exclusion criteria

This study does not include patients who:

  • have been treated
    – with 2 or more ATP-binding site TKIs (for second line patient cohort)
    – more than 4 weeks with 1-ATP-binding site TKIs (for first line patient cohort)
  • have been treated previously with asciminib
  • have known presence of a T315I mutation at any time before study entry
  • have a known second chronic phase of CML after previous progression to AP/BC.

Further criteria apply. Please discuss these with your doctor or study staff.
