Safety of a Contraceptive Copper Vaginal Ring

Many birth control options today come with unwanted side effects or risks. Hormonal methods can affect both mental and physical health, while devices like copper IUDs carry risks such as uterine perforation or infection. This study is testing a new option: a copper vaginal ring (CVR) - a non-hormonal, non-invasive contraceptive that can be self-inserted, similar to a other vaginal rings like NuvaRing or Annovera. The main goal of this study is to assess whether the copper vaginal ring is safe to use. Researchers will also look at how comfortable and easy it is to use, whether participants follow the instructions, and how much copper accumulates in cervical mucus and vaginal fluid during use. The study will enroll 8 women of childbearing age. Participants wear the ring continuously for 28 days, inserting it on Day 5 of their menstrual cycle. Over the course of the study, participants will attend 8 in-person clinic visits, which include pelvic exams, vaginal swabs, blood draws, and cervical mucus collection. On the day the ring is removed (Day 28), small tissue samples (biopsies) are taken from the vagina and uterine lining. At the end of the study, participants will complete a short survey about their experience with the ring.

International Active Surveillance Study: Native Estrogen Estetrol (E4) Safety Study

Multinational, comparative, prospective, active surveillance study that follows two cohorts. The primary objective of the study is to characterize and compare the risks of E4/Drospirenone (DRSP) with levonorgestrel-containing combined oral contraceptives (EE/LNG) in a study population that is representative of the actual users of these preparations. The main clinical outcome of interest is venous thromboembolism (VTE), specifically deep venous thrombosis (DVT) and pulmonary embolism (PE). Secondary objectives include measuring the occurrence of unintended pregnancy, assessing the risk of arterial thromboembolism (ATE), describing the drug utilization pattern, describing the baseline risk profile for VTE and ATE, and investigating outcomes associated with foetal exposure to E4/DRSP.
