What You Need to Know Before You Apply

What is the purpose of this trial?

This is a single arm phase II study that will enroll a minimum of 47 subjects with a maximum of 51. All patients will have a confirmed diagnosis of chronic phase chronic myeloid Leukemia and must have previously attempted to discontinue Tyrosine Kinase inhibitors (TKI). All patients must have restarted the same TKI they were on prior to discontinuation at the time of relapse in order to be eligible for this trial.

Do I need to stop my current medications for the trial?

The trial requires that you continue taking the same Tyrosine Kinase Inhibitor (TKI) you were on before your first attempt to stop treatment. You will need to stay on this medication for at least 12 months during the trial.

Is the combination of Asciminib and Imatinib safe for treating chronic myeloid leukemia?

Asciminib has shown a good safety profile in clinical trials for chronic myeloid leukemia, with common side effects including fatigue, low platelet counts, and anemia. It has fewer severe side effects compared to some other treatments, and no cardiovascular events were reported in one study.12345

How is the drug Asciminib + Imatinib unique for treating chronic myeloid leukemia?

Asciminib is a novel drug that targets a specific part of the BCR::ABL1 protein, known as the ABL myristoyl pocket, which is different from other treatments that target the ATP-binding site. This unique mechanism allows it to be effective in patients who have developed resistance or intolerance to other tyrosine kinase inhibitors, offering a new option for those with limited treatment choices.12467

What data supports the effectiveness of the drug combination Asciminib and Imatinib for treating Chronic Myeloid Leukemia?

Asciminib has shown strong effectiveness in treating chronic myeloid leukemia, especially in patients who have not responded well to other treatments. In clinical trials, it demonstrated better results and fewer side effects compared to another drug, bosutinib, making it a promising option for patients with limited treatment choices.12478

Are You a Good Fit for This Trial?

Adults diagnosed with chronic phase chronic myeloid leukemia (CP-CML) who have tried to stop taking imatinib once before but relapsed. They must be on imatinib again, agree to use two contraception methods if of childbearing potential, and meet specific health criteria including a stable molecular response for over two years and an ECOG performance status of 0-3.

Inclusion Criteria

Must have met all the following criteria prior to first attempt to discontinue their imatinib:
I have chronic phase CML with a specific protein variant.
- If they are of childbearing potential, agree to practice two effective methods of contraception from the time of signing of the informed consent form through 90 days after the last dose of study drug

I can care for myself but may not be able to do heavy physical work.
Any serious medical or psychiatric illness that could, in the investigator's opinion, interfere with the completion of treatment according to this protocol
I have completed 12 cycles of combination therapy.

What Are the Treatments Tested in This Trial?

Interventions

  • Asciminib
  • Imatinib
Trial Overview The trial is testing the combination therapy of Asciminib plus Imatinib in patients with CP-CML who previously relapsed after stopping treatment. It's a single-arm phase II study aiming for 41-51 participants to see if this combo can allow them to achieve treatment-free remission.

Published Research Related to This Trial

Asciminib is the first drug that specifically targets the ABL myristoyl pocket, showing promising efficacy and safety in patients with chronic myeloid leukemia (CML) who have previously been treated with multiple tyrosine kinase inhibitors (TKIs).
The ongoing phase III trial (ASC4FIRST) is comparing asciminib to standard TKIs in newly diagnosed CML patients, with the primary goal of achieving a major molecular response by week 48, highlighting its potential as a new treatment option.
Asciminib monotherapy for newly diagnosed chronic myeloid leukemia in chronic phase: the ASC4FIRST phase III trial.Cortes, JE., Hochhaus, A., Takahashi, N., et al.[2023]
Asciminib, a new treatment for chronic myeloid leukemia (CML), showed superior efficacy compared to bosutinib, with a major molecular response rate of 37.6% versus 15.8% after 96 weeks in patients who had previously been treated with two or more tyrosine kinase inhibitors.
Patients taking asciminib experienced fewer severe adverse events and were more likely to continue treatment without discontinuation, indicating better safety and tolerability compared to bosutinib.
Asciminib vs bosutinib in chronic-phase chronic myeloid leukemia previously treated with at least two tyrosine kinase inhibitors: longer-term follow-up of ASCEMBL.Hochhaus, A., Réa, D., Boquimpani, C., et al.[2023]
Asciminib is an allosteric inhibitor specifically designed for patients with chronic phase chronic myeloid leukemia (CP-CML) who are resistant or intolerant to at least two prior tyrosine kinase inhibitors (TKIs), showing a favorable safety profile and strong efficacy in clinical trials.
In a phase 3 trial, asciminib demonstrated a significantly higher major molecular response rate and lower discontinuation rate compared to bosutinib in patients with CP-CML who had previously failed two TKIs, indicating its potential as a more effective treatment option.
