Study Description

The purpose of this Chinese bridging study is to evaluate the efficacy, safety, tolerability and pharmacokinetics of asciminib versus best available therapy in Chinese patients with Chronic Myelogenous Leukemia in chronic phase, previously treated with 2 or more tyrosine kinase inhibitors to support related indication registration in China.

The primary objective of the study is to evaluate the Major Molecular Response (MMR) rate of asciminib treatment at 24 weeks.
