Cancer drug may weaken birth control: new study checks
NCT ID NCT07235774
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether the cancer drug vorasidenib changes how a common birth control pill works in 28 healthy women. Participants took the birth control pill alone, then later took it together with vorasidenib. Researchers measured drug levels in the blood and watched for side effects. The goal is to understand if women need extra contraception while taking vorasidenib.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- vorasidenib
- What this could lead to
- If successful, this study will show whether vorasidenib changes how birth control pills work, helping doctors advise women on effective contraception during treatment.
- What could go wrong
- This is a small, early-phase study in healthy volunteers, not patients. It only tests one type of birth control pill, so results may not apply to all contraceptives or to people with cancer.
