Popis

- Refractory to at least 1 cycle of induction chemotherapy, or
- Relapsed after at least 1 cycle of induction chemotherapy, or
- Patient is not, according to the clinical judgment of the Principal Investigator, a candidate for induction chemotherapy due to age, comorbidity, or other factors;

- Serum creatinine ≤ 2.0 mg/dL;

Number of Participants Achieving a Best Disease Response by Dose Cohort in Terms of Progressive Disease Following Oral Administration of Quizartinib in Participants With Relapsed or Refractory Acute Myeloid Leukemia
Časové okno: Baseline up to 28 days after the last dose, up to approximately 3 years
|
Progressive disease response criteria included doubling of blast count % in bone marrow (biopsy or aspirate) from baseline; considering measurements starting on Study Day 15, doubling of blast count % in blood from baseline; death determined to be related to disease or disease progression; and investigator reported disease progression.

Baseline up to 28 days after the last dose, up to approximately 3 years

Number of Participants Achieving a Best Disease Response by Dose Cohort in Terms of Best Overall Response Following Oral Administration of Quizartinib in Participants With Relapsed or Refractory Acute Myeloid Leukemia
Časové okno: Baseline up to 28 days after the last dose, up to approximately 3 years
|
Complete Response (CR) response criteria included either a post-baseline bone marrow (BM) biopsy or aspiration % blasts <5%, absolute neutrophil count (ANC) >1×10^9/L and platelet count >100×10^9/L on the same date as the qualifying BM assessment.
CRp response included all CR criteria met, except participant did not experience a platelet recovery (ANC recovery required).
CRi response included a qualifying BM result, but not an ANC recovery.
Participants may or may not have had a platelet recovery and were not required to be transfusion independent.
Partial remission (PR) response included a decrease of ≥50% in % blasts in the BM aspirate or biopsy from baseline to a post-baseline result between 5% to 25% in the bone marrow aspirate or biopsy.
Nonresponders (NR) had a pre- and 1 or more post-baseline BM assessment carried out, but results did not meet any response criteria.
Participants who were not evaluable (NE) did not have at least 14 days of treatment and were not assessed.

Number of Participants With Hematologic Improvement Following Oral Administration of Quizartinib in Participants With Relapsed or Refractory Acute Myeloid Leukemia
Časové okno: Baseline up to 28 days after the last dose, up to approximately 3 years
|
Hematologic improvement is summarized in terms of Erythroid Response (HI-E), Platelet Response (HI-P), Neutrophil Response (HI-N), and Hematologic Improvement (HI). For post-treatment results, HI-E major responders had >2 g/dL increase in hemoglobin for at least 1 result after first treatment and transfusion independent; minor responders 1 to 2 g/dL increase in hemoglobin for at least 1 result post first treatment and a 50% decrease in red blood cell transfusion requirements. For HI-P, major responders had ≥30 × 10^9/L increase in platelet count and transfusion independent; minor responders had 50% or more increase in platelet count with a net increase between 10 to 30 × 10^9/L and 50% decrease in platelet transfusion requirements. For HI-N, major responders had an increase in absolute neutrophil count (ANC) of 100% or an absolute increase of more than 0.5 × 10^9/L (whichever is greater); minor responders had an increase in ANC of 100% but an absolute increase of <0.5 × 10^9/L. |
