Frequently asked questions about Olverembatinib

What is Olverembatinib used for?

Olverembatinib is an investigational small molecule kinase inhibitor being studied for Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL), chronic myeloid leukemia (CML), and SDH-deficient gastrointestinal stromal tumors (GIST). It is also being evaluated in a pharmacokinetic study in participants with hepatic impairment.

How does Olverembatinib work?

Olverembatinib is a small molecule that belongs to the -tinib class of kinase inhibitors. It works by targeting and inhibiting specific kinases involved in cancer cell growth and survival. The drug is being studied across multiple oncology indications, including Ph+ ALL, CML, and GIST.

Who is developing Olverembatinib?

Olverembatinib is being developed by Ascentage Pharma Group International, which trades under the ticker AAPG on the American Depository Shares market. The company is conducting multiple clinical trials of the drug across various oncology indications.

What phase is Olverembatinib in?

Olverembatinib is in Phase 3 clinical development for Ph+ ALL, chronic myeloid leukemia, and SDH-deficient GIST. It is also in a Phase 1 pharmacokinetic study. The drug is investigational and has not been approved by regulatory authorities.

What clinical trials is Olverembatinib in?

Olverembatinib is being studied in several recruiting trials: NCT06051409 for newly diagnosed Ph+ ALL with 350 participants, NCT06423911 for chronic-phase CML with 285 participants, NCT06640361 for SDH-deficient GIST with 40 participants, and NCT07282093 for pharmacokinetics in hepatic impairment with 48 participants.

Is Olverembatinib the same as Olverembatinib 20mg?

Yes, Olverembatinib is also known as Olverembatinib 20mg. This alternative name refers to the same drug substance, which is being investigated in clinical trials for multiple oncology indications including Ph+ ALL, CML, and GIST.
