Condition(s) targeted: Unspecified Adult Solid Tumor, Protocol Specific
Intervention: paclitaxel (Drug); paclitaxel albumin-stabilized nanoparticle formulation (Drug)
Phase: Phase 1
Status: Active, not recruiting

RATIONALE: Drugs used in chemotherapy, such as paclitaxel and ABI-007, work in different ways
to stop tumor cells from dividing so they stop growing or die. Combining paclitaxel with
ABI-007 may kill more tumor cells.
PURPOSE: Randomized phase I trial to study the effectiveness of combining paclitaxel with
ABI-007 in treating patients who have locally advanced or metastatic solid tumors.
Official title: Randomized, Crossover, Pharmacokinetic Study Of Paclitaxel (Taxol) And ABI-007 (A Cremophor EL-Free, Protein Stabilized, Nanoparticle Paclitaxel) In Patients With Advanced Solid Tumors
Study design: Treatment
- Determine whether a change in the formulation alters the pharmacokinetic profile of
paclitaxel in the plasma of patients with incurable locally advanced or metastatic solid
tumors treated with ABI-007 and paclitaxel.
- Correlate pharmacokinetic data of this regimen with decrease in the neutrophil count at
nadir in these patients.
- Determine the intra- and interindividual pharmacokinetic variability of ABI-007 in these
- Determine protein binding of paclitaxel via measurement of α-1-acid glycoprotein and
serum albumin levels in patients treated with this regimen.
OUTLINE: This is a randomized, pilot study.
- Courses 1 and 2: Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive paclitaxel IV over 3 hours on day 1 and ABI-007 IV over 30
minutes on day 22.
- Arm II: Patients receive ABI-007 IV over 30 minutes on day 1 and paclitaxel IV over
3 hours on day 22.
- Courses 3 and beyond: All patients receive ABI-007 IV over 30 minutes on day 1. Courses
repeat every 21 days in the absence of disease progression or unacceptable toxicity.
