This is a Phase 1, randomized, open-label, 2-way crossover, pharmacokinetic study in adult patients with hematological malignancies eligible to receive either cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen or rituximab-CHOP (R-CHOP) regimen.
Eligible patients will be randomized in a 1:1 ratio to one of 2 treatment cohorts (Cohorts A or B) in which the Marqibo formulation and the 1-vial VSLI-RTU formulation of vincristine are administered in a 2-way crossover design over 2 treatment cycles (21 days each): * Cohort A: Marqibo formulation given at a dose of 2.25 mg/m2 with no dose cap during Cycle 1, and VSLI-RTU formulation given at 2.25 mg/m2 with no dose cap during Cycle 2. * Cohort B: VSLI-RTU formulation given at a dose of 2.25 mg/m2 with no dose cap during Cycle 1 and Marqibo formulation given at 2.25 mg/m2 with no dose cap during Cycle 2. Both formulations of vincristine sulfate LIPOSOME injection will be administered via a 60 (±10) minute IV infusion. Blood samples for PK evaluation will be drawn at the following time points: immediately before infusion, 0.5 hour after the start of the infusion, 0.5 hour after the end of infusion (EOI), and 3, 8, 15, 24, 48, 72, and 96 hours post-EOI. In addition to Marqibo or VSLI-RTU, all patients will receive standard doses (per institutional or regional guidelines) of cyclophosphamide, prednisone, and doxorubicin, (and rituximab if patient is on the R-CHOP regimen), on Day 1 and prednisone (or prednisolone if consistent with institutional or regional guidelines) on Days 2 to 5.

Eligible patients will be randomized in a 1:1 ratio to one of 2 treatment cohorts (Cohorts A or B) to receive either the first cycle of treatment with the VSLI-RTU formulation or the Marqibo formulation and crossover to the other formulation for the second cycle.
CHOP to be administered on Day 1 on Cycle 1 \& 2 ( 21-day Cycle) \& prednisone administration on Days 2 to 5 on Cycle 1 \& 2 ( 21-day Cycle)
R-CHOP to be administered on Day 1 on Cycle 1 \& 2 ( 21-day Cycle) \& prednisone administration on Days 2 to 5 on Cycle 1 \& 2 ( 21-day Cycle)
PK analysis Area under the concentration time curve (AUC)
To evaluate the serum pharmacokinetics (PK) of the 1-vial VSLI-RTU formulation versus the current Marqibo 3-vial formulation for intravenous (IV) injection.
