Brief Summary:
A Phase I Combination Study of CYC065 and Venetoclax for Relapsed or Refractory AML or MDS

Condition or disease Intervention/treatment Phase
AML MDS Drug: CYC065 Drug: Venetoclax Phase 1

Detailed Description:
This is an open-label, single arm, dose escalation study in patients with relapsed or refractory AML or MDS. Treatment will be administered on an outpatient basis and all patients will receive CYC065 over 4-hour infusion once every 2 weeks on Day 1 and Day 15 in combination with venetoclax. One treatment cycle is 4 weeks.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 25 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: One to 6 patients will be entered at a given CYC065 dose level. Dose escalation will be 33% after at least one patient has completed the first treatment cycle without ≥ grade 2 toxicity considered by the investigator to be related to CYC065. Upon the first occurrence of grade 2 toxicity related to CYC065, at least 3 patients will be entered at each dose level. If no DLT is observed in any patients, dose escalation will continue to be 33%. If one of 3 patients experienced a DLT at a given dose level, dose escalation will continue at 25% until MTD is reached. If 2 or more patients experienced a DLT at a given dose level, dose escalation will be stopped. At least 6 patients will be treated at MTD.
Masking: None (Open Label)
Primary Purpose: Treatment
