Leukemia drug Asciminib's Long-Term safety tracked in ongoing study
NCT ID NCT04877522
First seen Jun 25, 2026 · Last updated Jul 07, 2026 · Updated 3 times
Summary
This study follows people with chronic myeloid leukemia (CML) who have already benefited from the drug asciminib in earlier Novartis trials. Researchers want to see how safe the drug is over the long term. About 347 participants will continue taking asciminib or other similar drugs and be monitored for side effects. No new treatment is being tested—this is about checking safety for those already on the medication.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Asciminib (also known as ABL001), imatinib, nilotinib, bosutinib, dasatinib
- What this could lead to
- If successful, this study will confirm that long-term use of asciminib is safe for controlling chronic myeloid leukemia.
- What could go wrong
- This is an observational roll-over study, not a test of a new treatment. It only includes patients already benefiting, so results may not apply to everyone. Side effects are still possible.

Key Inclusion Criteria: 1. Participant with PH+ CML or PH+ ALL currently receiving treatment with asciminib (single agent or in combination with imatinib, nilotinib or dasatinib), imatinib, nilotinib or bosutinib alone within a Novartis-sponsored study and, in the opinion of the Investigator, would benefit from continued treatment. 2. Participant has demonstrated compliance on the parent study protocol and is willing and able to comply with scheduled visits, treatment plans and any other study procedures. Key Exclusion Criteria: 1. Participant has been discontinued from parent study treatment. 2. Participant currently has unresolved toxicities reported as possibly related to study treatment in the parent study. 3. Participant's ongoing treatment is currently approved and reimbursed at country level. 4. Pregnant or nursing (lactating) women. 5. Women of child-bearing potential, unless they are using highly effective methods of contraception and willing to continue while taking study treatment. 6. Sexually active males receiving imatinib, nilotinib, bosutinib or dasatinib unwilling to follow the relevant contraception requirements in the local prescribing information. 7. Applicable for participants on bosutinib treatment at the end of the CABL001A2301 and on other TKIs for CABL001A2202 study that switch to asciminib treatment: * Asymptomatic (grade 2) pancreatitis if not resolved within 28 days * QTcF\>480msec or inability to determine QTc interval * any grade 3 or 4 toxicity not resolved to grade 2 or lower within 28 days before starting asciminib treatment Other protocol-defined Inclusion/Exclusion criteria may apply.
