Brief Summary:
A Phase I Pharmacologic Study of CYC140, a polo-like kinase 1 inhibitor, in Patients with Advanced Leukemias or Myelodysplastic Syndromes

Condition or disease Intervention/treatment Phase
AML, Adult Myelodysplastic Syndromes ALL, Adult CML, Refractory CLL, Refractory Drug: CYC140 Phase 1

Detailed Description:
This is a First in Human, open-label, single arm, dose escalation study in patients with advanced leukemias or myelodysplastic syndromes. Patients will receive CYC140 as a 1 hr infusion once a week for 2 weeks followed by 1 week of rest on an outpatient basis. One treatment cycle is 3 weeks.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 50 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: One to three patients will be entered at a given dose level of CYC140. During the first cycle, all patients will be evaluated for DLTs. If DLT occurs, additional patients (up to 3) will be dosed at that dose. If no additional DLTs observed, dose escalation will continue per protocol. If a DLT does occur, dose escalation will be stopped. At least 6 patients will be treated at the RD to confirm its tolerability.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I Pharmacologic Study of CYC140, a Polo-like Kinase 1 Inhibitor, in Patients With Advanced Leukemias or Myelodysplastic Syndromes
Actual Study Start Date : March 25, 2019
Estimated Primary Completion Date : April 2023
Estimated Study Completion Date : September 2023

CYC140 will be administered as a single agent on Day 1 and Day 8 of each 3 week cycle
Drug: CYC140
CYC140 single agent

Primary Outcome Measures :
  1. Number of Patients who experience dose -limiting toxicity (DLT) [ Time Frame: At end of cycle 1 (each cycle is 21 days) ]
