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.

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.
