NCT03187288
Lead Sponsor
University Health Network, Toronto
Brief Summary

This is a phase 1 study of investigational drug CFI-400945 in patients with relapsed or refractory acute myeloid leukemia or myelodysplastic syndrome. The purpose of this phase 1 study is to see how safe and tolerable the study drug is and to determine the best dose (maximum tolerated dose or recommended phase 2 dose) that can be given in this patient population.

Detailed Description

Participants will be screened prior to the start of the study drug for eligibility.

Eligible participants will take CFI-400945 by mouth, once a day, every day of each 28 day cycle. Participants will be asked to keep a study drug diary.

While receiving the study drug, participants will have standard tests and procedures done for safety purposes.

Procedures for research purposes include bone marrow aspirate and additional blood collection for biomarker research, and additional blood samples for pharmacokinetic research.

When participants stop the study drug permanently for any reason, they will be asked to have an End of Treatment Visit and be followed for safety purposes.

Primary Outcome Measures
NameTimeMethod
Evaluation of the frequency and severity of treatment-emergent adverse events in patients5 years

This will be done to assess safety and tolerability of CFI-400945 fumarate

Highest tolerated dose of CFI-400945 fumarate5 years

The Maximum Tolerated Dose MTD is defined as the highest dose level that does not lead to unacceptable toxicity in two or more patients in a dosing cohort.

Recommended phase 2 dose of CFI-400945 fumarate5 years

Following completion of dosing of at least 1 cycle for all patients enrolled the Recommended Phase 2 Dose (RP2D) will be determined.It will be based upon the MTD established during dose escalation and its comprehensive outcome

Secondary Outcome Measures
NameTimeMethod
Number of participants with response to treatment5 years

Patients responses will be assess using the International Working Group response criteria for AML and MDS.
