About this study
Official title: Asciminib as Single Agent or in Combination With Nilotinib in the 1st-line Treatment of BCR-ABL1+ Chronic Myeloid Leukemia: a Randomized GIMEMA-GELMC Phase II Study PEARL Study: PotEntial of Asciminib in the eaRly Treatment of CML
A phase 2, interventional, randomized unblinded study will be conducted in newly diagnosed CP CML patients, to investigate the efficacy and the safety of asciminib at a dose of 80 mg QD as single agent (arm A) or 40 mg BID in combination with nilotinib 300 mg BID (arm B).
All patients in both arm A and arm B will be treated for a minimum of 2 years (core phase). If they will have achieved a DMR (MR4), or if it will be in the interest of the patient, the treatment will be continued.
Read more
During the consolidation phase (2 years) asciminib will be continued at the same dose in both arms; in the combination arm the nilotinib dose will be reduced to 300 mg daily.
The patients maintaining a stable MR4 up to the end of the fourth year will discontinue the treatment (TFR phase). The rate of TFR at 5 year (1 year after discontinuation) will be evaluated.
Read the detailed description
A phase 2, prospective, interventional, randomized (two arms, randomization 1:1), unblinded study will be conducted in newly diagnosed CP CML patients, to investigate the efficacy and the safety of asciminib at a dose of 80 mg QD as single agent (arm A) or 40 mg BID in combination with nilotinib 300 mg BID (arm B).
- In the arm A, asciminib 80 mg QD will be given as single-agent. In the arm B, asciminib 80 mg QD will be started, then after 90 days asciminib will be given 40 mg BID and nilotinib 300 mg BID, or 300 mg OAD according to the presence/absence of asciminib adverse events, will be added-on in all patients. All patients in both arm A and arm B will be treated for a minimum of 2 years (core phase). If they will have achieved a DMR (MR4), or if it will be in the interest of the patient, the treatment will be continued. In both arms the study drugs may be discontinued at any time for inefficacy (failure) or safety reasons(grade 3-4 toxicity or persistent grade 2 non hematologic toxicity). However, all the patient will remain "in study" (regular follow-up information will be required). The dose adjustments for toxicity and detailed criteria for treatment discontinuation (asciminib in arm A; asciminib or nilotinib in arm B) are specified within the protocol.
- After the induction of a DMR, the residual disease will be closely monitored by Q-PCR until the fourth year (consolidation phase). During the consolidation phase (2 years) asciminib will be continued at the same dose in both arms; in the combination arm the nilotinib dose will be reduced to 300 mg daily.
- The patients maintaining a stable MR4 up to the end of the fourth year, that must include in the last year at least 3 evaluable QPCR analyses, will enter the treatment free remission (TFR) phase of the study and will discontinue the treatment (TFR phase). A single unconfirmed loss of MR4 will not preclude the possibility of treatment discontinuation. In case of confirmed loss of MR3 after discontinuation, the choice of subsequent treatment will be up to Local Investigators. The rate of TFR at 5 year (1 year after discontinuation) will be evaluated.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Asciminib and Nilotinib in people with CML, Chronic Phase and Chronic Myeloid Leukemia, Chronic Phase, run by Gruppo Italiano Malattie EMatologiche dell'Adulto at 11 sites in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Paola Fazi (0670390528, p.fazi@gimema.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
evaluation of response of asciminib single-agent or in combination with nilotinib (time frame: at 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2025.
