Marqibo® (Vincristine sulfate liposomal) will be administered intravenously over 60 minutes (±10 minutes) every 7 days (±3 days) (Days 1, 8, 15, 22) for four doses (1 cycle). Cycles may be repeated every 28 days for a maximum of 6 cycles; additional cycles may be offered with evidence of acceptable toxicity and clinical benefit.
The trial follows a rolling phase I design with 2 to 6 subjects per dose level and standard definitions of MTD and DLT. At the MTD, a total of 6 additional subjects with relapsed or refractory ALL will be evaluated.
Detailed pharmacokinetic studies will be performed during the first treatment cycle

Toxicity was graded according to the version 4.0 of the NCI Common Toxicity Criteria (CTCAE v4.0).

The MTD was defined as the dose level immediately below the dose level at which ≥2 subjects in a cohort of 2 to 6 subjects experienced a DLT.

DLT was graded according to the version 4.0 of the NCI Common Toxicity Criteria (CTCAE v4.0). Adverse events (AEs) that were considered disease-related (not suspected of relationship to Marqibo) were not considered dose-limiting toxicities. Only those AEs deemed suspected of a relationship to Marqibo were used in the definition of DLT.

PK samples were collected at cycle 1 before start of first infusion, 5 minutes post-infusion and at 1, 3, 6, 10, 24, 48, 72, 96, 120 and 144 hours (pre-dose #2 trough level). Area under the concentration time curve (AUC) to last measured time point after dose one was calculated via linear trapezoidal method and extrapolated to infinity (AUC0-∞) by adding the last plasma concentration after dose one divided by the rate constant, derived from the slope of the natural log-transformed concentrations and times on the terminal elimination phase of the concentration-time curve.
