Study of a Novel BET Inhibitor FT-1101 in Patients With Relapsed or Refractory Hematologic Malignancies

• Status: Completed
• Trial end date: 2019-03-01
• Target enrollment: 0
• Participant gender: All

Summary

This is an open-label, multicenter, dose-escalation Phase 1/1b study in patients with acute myelogenous leukemia (AML)/MDS or non-Hodgkin Lymphoma (NHL), intended to investigate safety, pharmacokinetics, and the pharmacodynamic effects of FT-1101 administered via one or more intermittent dosing schedules alone and in combination with azacitidine. Once the MTD has been established for a treatment cohort, up to 20 additional patients may be enrolled in up to 4 expansion cohorts each of select populations of patients with either AML/MDS or NHL at the recommended dose for future studies to confirm safety.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Forma Therapeutics, Inc.
• Treatments: Azacitidine

Criteria

Key Inclusion Criteria:

• Single agent (SA) Dose Escalation: Histologically or cytologically proven acute leukemia or high-risk MDS as defined by the World Health Organization (WHO) criteria and IPSS-R, respectively, that is relapsed or refractory (R/R) to standard therapy or for whom standard treatments are contraindicated, OR

• Mature B-Cell non-Hodgkin Lymphoma that is Relapsed/Refractory to standard therapy

• AML SA expansion group 1: histologically or cytologically proven AML with a FLT3 ITD or TKD mutation previously determined by local testing that is R/R to standard therapy or for whom standard treatments are contraindicated

• AML SA expansion group 2: histologically or cytologically proven AML with intermediate or unfavorable risk cytogenetics in the absence of a detectable FLT3 ITD or TKD mutation as previously determined by local testing that is R/R to standard therapy or for whom standard treatments are contraindicated

• NHL SA expansion: Mature B-cell NHL with the following histologies: primary mediastinal lymphoma, DLBCL, and B-cell lymphoma not specified that is R/R to standard therapy and for whom standard treatments are contraindicated or unavailable

• AML/MDS combination treatment (dose escalation and expansion): histologically or cytologically proven AML or MDS as defined by WHO criteria and IPSS-R, respectively, that is: R/R to standard therapy, or AML: who are unfit for, or unwilling to receive standard induction therapy, or MDS: eligible to receive azacitidine
