A Phase Ⅰb/Ⅱ Clinical Study of Clifutinib Besylate Combined With Chemotherapy in the Treatment of Newly Diagnosed AML

Официальное название

A Phase Ib/II, Multi-center, Open Clinical Trial of Crifortinib Besylate Combined With Chemotherapy in Newly-treated Adult Subjects With Acute Myeloid Leukemia

Обзор

This is a multi-center open clinical study aimed at evaluating the efficacy and safety of Clifutinib Besylate combined with chemotherapy in newly-treated adult subjects with AML

Подробное описание

Main purpose:To evaluate the tolerability and safety of Clifutinib Besylate combined with DA (Cytarabine + Daunorubicin) or AZA (Azacitidine) in newly-treated adult AML subjects; explore reasonable therapeutic doses through climbing tests in different dose groups.

To evaluate the efficacy of Clifutinib Besylate combined with DA or AZA in newly treated adult AML subjects.

Secondary purpose:To observe the pharmacokinetic (PK) characteristics of Clifutinib combined with DA or AZA in newly-treated adult AML subjects and the drug interaction between Clifutinib and AZA at the same time.Observe the correlation of different subtypes and prognostic risk with the efficacy of Clifutinib and the changes of genes before and after treatment.

Критерии участия

Критерии включения
