Purpose

The primary objective of this pharmacokinetics study is to compare the maximum concentration level of paclitaxel in patients with low/sarcopenic skeletal muscle area (SMA), at the end of a 2-3 hour paclitaxel infusion, to the maximum level in patients with normal SMA at the end of a standard 1-hour infusion with the goal of determining whether lengthening the infusion in patients with low/sarcopenic SMA normalizes the levels to those of patients with normal SMA.

Inclusion Criteria

Exclusion Criteria

  • Concomitant administration of any moderate or strong inducer or inhibitor of CYP2C8, including rifampin or clopidogrel. - History of hypersensitivity reaction to paclitaxel or any components of paclitaxel (e.g., Cremophor EL) that precludes continued treatment with standard dose and infusion length - Pregnant or nursing - Receiving any other dose (i.e., not 80 mg/m2) or infusion rate (i.e., not 60 minute infusion) either due to toxicity during a previous cycle or any other reason

Active Comparator
Normal SMA (>7310 mm^2)
Standard paclitaxel infusion time.
  • Drug: Paclitaxel
    Weekly intravenous (IV) infusion of a standard dose of paclitaxel 80 mg/m^2. Dose 1 is a 90-minute infusion. All other doses administered as a 1-hour infusion for a total of 12 weekly doses.

    • Taxol
Experimental
Low SMA (5120 - 7310 mm^2) and Sarcopenic SMA (<5120 mm^2)
Adjusted paclitaxel infusion time during only one dose; standard paclitaxel infusion time for all other doses.
  • Drug: Paclitaxel
    Weekly intravenous (IV) infusion of a standard dose of paclitaxel 80 mg/m^2. Dose 1 is a 90-minute infusion. During doses 2-12, patients with low SMA will receive one 2-hour infusion and patients with sarcopenic SMA will receive one 3-hour infusion. All other doses during weeks 2-12 are standard infusion time.

Detailed Description

Paclitaxel is an FDA-approved and commonly used standard of care agent for patients with early-stage breast cancer. This study will use the standard dose of 80 mg/m^2, including the typical pre-medications as per University of Michigan Rogel Cancer Center institutional standard. The only investigational component of this study is lengthening the infusion duration from 1-hour to 2 or 3 hours for a single dose in patients with low SMA. JAN2025 update, Paclitaxel is an FDA-approved and commonly used standard of care agent for patients with early-stage breast cancer or metastatic gastric or esophageal cancers.
