Phase 1/2 — A combined trial that checks safety and dosing while also starting to look at whether the treatment works.
This trial is testing how a birth control pill called works in the body before and after weight loss surgery. Researchers want to understand whether weight loss surgery changes how the body absorbs and processes this medication. This information will help doctors know if the birth control pill remains effective for women who have had this type of surgery.
Weight loss surgery changes how the digestive system works, which can affect how the body absorbs medications—including birth control pills. Doctors need to know whether this medication remains reliable after surgery so women can make informed choices about contraception.

You would take the birth control pill once daily for 21 to 28 days before your weight loss surgery, during which time blood samples would be collected to measure how your body processes the medication. After your surgery has healed and you've recovered, you would repeat the same process—taking the pill daily for 21 to 28 days and having blood samples taken again. This allows researchers to compare how your body handled the medication before and after surgery.
