A Phase 3 interventional study of Quizartinib and Salvage Chemotherapy in AML, sponsored by Daiichi Sankyo. Completed at 131 sites in 19 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2021-02-24.
Sponsored by Daiichi Sankyo · Phase 3, Interventional, and Treatment
The primary objective of the study is to determine whether quizartinib monotherapy prolongs overall survival (OS) compared to salvage chemotherapy in subjects with FMS-like tyrosine kinase 3 - Internal Tandem Duplication (FLT3-ITD) positive AML who are refractory to or have relapsed within 6 months, after first-line AML therapy.
5,441 studies on the registry are indexed under Leukemia; 636 are open to participants now.
This study's enrollment of 367 is above the median of 38 across 4,247 interventional studies indexed under Leukemia.

Exclusion Criteria:
Participants who were randomized to receive 20 or 30 mg quizartinib tablets administered orally once daily.
Drug: Quizartinib
Participants who were randomized to receive salvage chemotherapy, such as low dose cytarabine (LoDAC); mitoxantrone, etoposide, and intermediate-dose cytarabine (MEC); or fludarabine, cytarabine, and granulocyte colony stimulating factor (G-CSF) with idarubicin (FLAG-IDA), were administered during 28-day cycles.

20 or 30 mg quizartinib tablets administered orally once daily
Also known as: AC220
Low dose cytarabine (LoDAC); mitoxantrone, etoposide, and intermediate-dose cytarabine (MEC); or fludarabine, cytarabine, and granulocyte colony stimulating factor (G-CSF) with idarubicin (FLAG-IDA) administered during 28-day cycles

Overall Survival in Participants That Received Quizartinib Versus Salvage Chemotherapy
Overall Survival is defined as the time (in weeks) from the date of randomization to the date of death due to any cause. Median and quartiles are calculated using the Kaplan-Meier method.
Time frame: At approximately 3 years 9 months
Event-free Survival in Participants That Received Quizartinib Versus Salvage Chemotherapy
Event-free survival is defined as the time (in weeks) from randomization until documented refractory disease, relapse after complete composite remission (CRc), or death from any cause, whichever is observed first.
Time frame: At approximately 3 years 9 months
A total of 367 participants who met the inclusion and none of the exclusion criteria were randomized (intent-to-treat population); 335 received study drug (safety analysis set).

Collected over Treatment-emergent adverse events (TEAEs) were collected from the first dose of study drug to 30 days after the last dose (or longer if assessed as treatment related). All safety events are reported for participants in the Safety Analysis Set who received at least 1 dose of study drug or salvage chemotherapy.. Non-serious events are listed at a 5% frequency threshold.
