A Study of E6201 for the Treatment of Advanced Hematologic Malignancies With FLT3 and/or Ras Mutations

Draft scope assessment: unclear. Attached because the study's own record names FLT3. The study was not selected for this indication by its sponsor, and its eligibility has not been reconciled against this page in full. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

primary · POSTED

Phase 1 (Safety Run-In) was conducted in 5 dose cohorts in up to 30 subjects in a standard 3+3 dose-escalation design to establish an MTD and recommended Phase 2 dose (RP2D). Safety assessed through the monitoring of adverse events (AEs), serious adverse events (SAEs), clinical laboratory parameters (hematology and serum chemistry), vital sign measurements, electrocardiograms (ECGs) and physical examinations.

primary · POSTED

A DLT was defined as any one of the following events: prolonged myelosuppression (as defined by the National Cancer Institute \[NCI\] criteria specific for leukemia, i.e., marrow cellularity \< 5% at ≥ 6 weeks from start of therapy without evidence of leukemia); ≥ Grade 3 non-hematologic toxicity (excluding Grade 3 nausea, vomiting or diarrhea that is adequately controlled with supportive care and resolves to ≤ Grade 2 within 48 hours, or Grade 3 electrolyte disturbances responsive to correction within 24 hours); ≥ Grade 3 liver function tests (LFTs) lasting \> 7 days; treatment interruption \> 14 days due to toxicity; or other important medical event. DLTs were collected to determine the MTD which is defined as the dose level below the dose at which ≥ 2 of 6 patients in a dose cohort experienced a DLT.

secondary · POSTED

For acute myeloid leukemia (AML): Revised Recommendations of the International Working Group (IWG) Response Criteria for AML: CR: Free of leukemia-related symptoms, absolute neutrophil count (ANC) \> 1.0 x 10\^9/L, platelet count ≥ 100 x 10\^9/L, normal bone marrow with \< 5% blasts and no Auer rods. CRi: As per CR but w/ residual thrombocytopenia (platelet count \<100 x 10\^9/L) or residual neutropenia (ANC \<1.0 x 10\^9/L). PR: ≥50% decrease bone marrow blasts to 5 - 25% abnormal cells, or CR w/ ≤ 5% blasts if Auer rods present. For myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia (CMML): Modified IWG Response Criteria for MDS: CR: Free of leukemia-related symptoms, ANC ≥1.0 x 10\^9/L, platelet count ≥100 x 10\^9/L, bone marrow ≤5% myeloblasts, normal maturation of all cell lines, hemoglobin ≥ 11g/dL, no blasts in the peripheral blood. PR: All CR criteria w/ ≥50% decrease in bone marrow blasts over pre-treatment, but still \> 5%.

The analysis population was the per-protocol set (PPS). The PPS included all subjects in the FAS who had a valid baseline and one or more post-treatment assessments for a specified measure.

Length of time from the first evidence of objective response to the first evidence of progression

The analysis population was the per-protocol set (PPS). The PPS included all subjects in the FAS who had a valid baseline and one or more post-treatment assessments for a specified measure. No objective responses were observed. Therefore, duration of response could not be calculated.

secondary · POSTED

Length of time from the date of first administration of study drug to the first evidence of disease progression or death, whichever is earlier

The analysis population was the per-protocol set (PPS). The PPS included all subjects in the FAS who had a valid baseline and one or more post-treatment assessments for a specified measure. For AML, MDS and CMML, progression was defined by relevant IWG criteria as failure to achieve at least a PR. No responses; PFS could not be calculated.
