Efficacy and Safety of Generic Dasatinib as a Second-line Treatment for Patients with Chronic Myeloid Leukemia: a Multicenter Retrospective Study in Hubei Province, China
Dasatinib is a second-generation tyrosine kinase inhibitor (TKI) and it could be used as a second-line treatment for patients with chronic myeloid leukemia (CML). Yinishu, a generic dasatinib made in China, was approved by the China Food and Drug Administration in 2013 and it costs much less than the patented dasatinib SPRYCEL. The present study aimed to examine the efficacy and safety of Yinishu as a second-line treatment for CML by comparing the baseline clinical characteristics, rates of adverse events and efficacy between Yinishu and SPRYCEL groups. The results showed that there were no significant differences in the rates of optimal response between Yinishu and SPRYCEL for patients who started second-line treatment because of treatment failure. For patients who started second-line treatment because of intolerance of first-line treatment, their levels of BCR-ABL1/ABL1 on the international scale (BCR-ABLIS) was maintained very low throughout the course of Yinishu treatment. Drug-related adverse events occurred with the same frequency in these two groups. It was confirmed that Yinishu was effective and safe as a secondline treatment for CML patients. Yinishu may be more suitable for patients who are economically unable to pay for the patented dasatinib SPRYCEL.
