Vion initiates Phase I/II cancer trial for Cloretazine with cytarabine

The objectives of the trial are to define the maximum tolerated dose (MTD) of Cloretazine (VNP40101M) when given in combination with cytarabine to acute myelogenous leukemia (AML) and high-risk myelodysplastic syndromes (MDS) patients over the age of 60, and to evaluate this combination further for safety and efficacy in a larger cohort of patients.

Cloretazine (VNP40101M) will be given as a 30 to 60 minute infusion on day one approximately three to four hours after the start of the cytarabine infusion. Cytarabine will be administered as a continuous infusion of 100mg/m2/day for seven days. In the Phase I portion of the study, dose escalation will be done in cohorts of at least three patients and the maximum tolerated dose (MTD) identified in the Phase I segment will be used in the Phase II segment of the study.

The trial is being conducted under the direction of Ellen Ritchie, at the Weill-Cornell Medical College in New York City. Co- investigators for the study are Eric Feldman, and Gail Roboz.
