What this trial studies

This Phase III clinical study evaluates the effectiveness of Clifutinib in treating Chinese patients with relapsed or refractory FLT3-mutated acute myeloid leukemia (AML) compared to standard salvage chemotherapy. Participants aged 18 and older will be randomized in a 2:1 ratio to receive either Clifutinib or a pre-selected salvage chemotherapy regimen. The study aims to assess overall survival and the rate of complete response or complete response with partial hematologic recovery. Following treatment, participants will undergo safety follow-ups and long-term monitoring.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with relapsed or refractory FLT3-mutated AML who have previously undergone first-line therapy.

Not a fit: Patients who have received prior treatment with other FLT3 inhibitors or those with AML that has relapsed after multiple lines of therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option that improves survival rates for patients with relapsed FLT3-mutated AML.

How similar studies have performed: Other studies have shown promising results with FLT3 inhibitors in AML, suggesting that this approach may be effective.
