ABSTRACT

The article describes the outcomes of Genfatinib® therapy in routine clinical practice at the Regional Oncology Clinic (Penza) and Yaroslavl Regional Clinical Hospital (Yaroslavl). 62 patients with chronic myeloid leukemia (chronic phase) were treated at the above institutions from April 2012 to April 2013. The patients were assigned into the following groups: the first treatment group, where Genfatinib® was prescribed as an initial therapy at the time of diagnosis of chronic-phase chronic myeloid leukemia; the second group, where Genfatinib® was prescribed after the initial therapy with Gleevek®. The main objectives were assessment of the Genfatinib® efficacy (rates of complete or partial clinico-hematological, cytogenetic, and molecular responses), toxicity, and safety. It was shown that Genfatinib® used after previous therapy with Gleevek® caused no negative influence of the rates of clinico-hematological, cytogenetic, and molecular responses. In the patients who received Genfatinib® as an initial therapy, the complete clinico-hematological and cytogenetic and molecular responses were achieved by 3–5 and 3–6 months of treatment, respectively. The spectrum of adverse events observed with Genfatinib® therapy was similar to the one of Gleevek®.

Keywords: chronic myeloid leukemia, chronic phase, Genfatinib®, efficacy, safety.
