Frequently asked questions about Asciminib add-on

What is asciminib add-on used for?

Asciminib add-on is being studied in chronic myeloid leukemia (CML) in chronic phase. Specifically, it is added to imatinib for patients previously treated with imatinib who have not achieved a deep molecular response. This combination approach aims to improve treatment outcomes for CML patients who need deeper responses.

What does asciminib add-on target?

Asciminib add-on targets the ABL1 kinase and the BCR-ABL1 fusion protein, which drives chronic myeloid leukemia. It is a small molecule inhibitor that binds to the ABL1 myristoyl pocket, offering a distinct mechanism of action compared to ATP-competitive inhibitors. This target specificity is central to its therapeutic potential in CML.

Who is developing asciminib add-on?

Asciminib add-on is being developed by Novartis AG, a multinational pharmaceutical company. Novartis is listed on the New York Stock Exchange under the ticker symbol NVS. The company is evaluating this combination therapy in clinical trials for chronic myeloid leukemia.

What phase is asciminib add-on in?

Asciminib add-on is in Phase 2 clinical development. It has been tested in a completed Phase 2 trial, and further studies may be planned. As an investigational therapy, it has not been approved by regulatory agencies for this specific add-on indication.

What clinical trials is asciminib add-on in?

Asciminib add-on has been evaluated in a Phase 2 clinical trial, NCT03578367. This study was completed and enrolled 104 patients with chronic myeloid leukemia in chronic phase who had previously received imatinib and had not achieved a deep molecular response. The trial was active-controlled and randomized.
