NCT ID NCT05858398

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether body composition (fat and muscle) changes how the chemotherapy drug docetaxel behaves in women with early breast cancer. Researchers will compare drug levels in obese, overweight, and lean patients using blood samples and CT scans. The goal is to see if current dosing based on body surface area needs adjustment for body fat.
