NCT ID NCT06052345
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This study follows women with early-stage breast cancer who are about to receive paclitaxel chemotherapy, a treatment that often causes nerve damage. Researchers will use smartwatches and a mobile app to track physical activity, sleep, and stress, alongside clinical exams and skin biopsies. The goal is to find early warning signs of nerve damage and understand how it affects quality of life over a year.
