New drug aims to ease menstrual cramps in phase 3 trial

NCT ID NCT05640232

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

Summary

This Phase 3 trial is testing a new drug called CDE100 to see if it relieves menstrual cramp pain better than a current treatment (Buscopan Composto). About 238 women aged 16-35 with moderate to severe cramps will take part. The study is double-blind, meaning neither participants nor doctors know who gets which treatment, and it uses a crossover design so each person tries both drugs at different times.
