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.
What this could mean

What this could lead to
If successful, this could provide a new, effective option for relieving menstrual cramp pain in women with primary dysmenorrhea.
What could go wrong
This is a Phase 3 trial, but results may not show a significant advantage over existing treatments. Individual responses to pain relief vary, and the drug may not work for everyone.
