Study Description

Brief Summary: In this study, Liposome Entrapped Paclitaxel Easy to Use (LEP-ETU) is being compared to Taxol® to examine whether the paclitaxel in these 2 formulations undergoes similar processing by the body. Safety and tolerability of LEP-ETU and Taxol will also be assessed. In this study, each patient will receive one intravenous infusion of LEP-ETU or Taxol, followed 3 weeks later by an infusion of the other drug, at the same dose and infusion duration. Multiple blood samples will be taken for analysis before, during, and after both drug infusions. Upon completing these 2 Cycles of treatment, eligible patients may enroll in an extension study (LEP-ETU-102B) to continue treatment with LEP-ETU. LEP-ETU is a liposomal formulation of paclitaxel, a widely used anti-cancer drug. This LEP-ETU formulation of paclitaxel is being developed to potentially reduce toxicities associated with Taxol, by eliminating the drug formulation component polyoxyethylated castor oil (Cremophor® EL). In LEP-ETU, paclitaxel is associated with liposomes, which are microscopic membrane-like structures created from lipids (fats). Thus, the LEP-ETU formulation could potentially have reduced toxicity, while maintaining or enhancing efficacy.

Detailed Description: This Phase 1B, open-label, two-period crossover bioequivalence study is designed to compare the pharmacokinetics (PK) of LEP-ETU and Taxol in patients with advanced cancer. Patients are randomized to determine which drug is administered first. A single dose of LEP-ETU or Taxol (Cycle A) will be administered, followed 3 weeks later by a single dose of the other drug (Cycle B). Blood samples for PK analysis will be taken before, during, and after the infusion of each drug. Following successful completion of both Cycles in this study, patients may be eligible for additional cycles of treatment with LEP-ETU in the LEP-ETU-102B extension study.
