NCT ID NCT05515354
First seen Mar 29, 2026 · Last updated Apr 30, 2026 · Updated 6 times
Summary
This study tests whether starting a quit attempt during the first half of the menstrual cycle (follicular phase) helps women stop smoking more successfully than starting during the second half (luteal phase) or without cycle timing. About 1,200 women who smoke daily and have regular periods will use nicotine patches or gum and track their quit progress. The goal is to find a simple, hormone-aware strategy to improve quit rates and prevent smoking-related cancers.
