Study start date: August 24, 2022

Actual date on which the first participant was enrolled.

This clinical trial aims to study how a medication called Evobrutinib (also known as M2951) affects the way a commonly used oral contraceptive, which contains Ethinyl estradiol and Norethisterone, is processed in the body. The study involves healthy female participants who are not currently using any hormonal contraceptives. Understanding this interaction is important because it can help ensure that women using both Evobrutinib and this contraceptive have effective and safe contraception. Participants in the study will be staying at a Clinical Research Unit for up to 18 days. During this time, they will take Evobrutinib pills for 14 days and the oral contraceptive on two separate days. Researchers will monitor how the contraceptive is absorbed and processed in the body when taken with Evobrutinib. This is done through regular blood tests and medical check-ups to gather data. The study is designed to ensure participant safety and aims to provide valuable information about potential interactions between these medications.
