Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This completed phase 1 study looked at how imlunestrant, a potential cancer drug, affects the body's handling of other medications like repaglinide, omeprazole, and dextromethorphan. It also tested how quinidine changes imlunestrant levels. 113 healthy women of non-childbearing potential took part to measure drug levels and safety. The goal is to understand possible drug interactions before imlunestrant is used in patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Imlunestrant
What this could lead to
If successful, this study will help doctors understand how imlunestrant interacts with other medications, guiding safer use in future patients.
What could go wrong
This is an early-phase study in healthy volunteers, not patients. It focuses on drug interactions, not treatment effects, so results may not predict real-world outcomes.
