UC Davis Health Clinical Studies

Have heavy menstrual bleeding? Participate in a research study to test an intrauterine device (IUD) treatment.

We're evaluating if an IUD is safe and effective in helping women with heavy periods

We're inviting women with heavy menstrual bleeding who are not interested in being pregnant in the next 10 months. This goal of this study is to see if an intrauterine device (IUD) is safe and effective in women with heavy menstrual bleeding. This study will use an IUD that is already on the market in the United States and approved by the FDA, called Liletta®. An IUD is a device placed in the uterus to prevent pregnancy. We want to know if an IUD can be a safe and effective treatment for women with heavy menstrual bleeding. This clinical research study happens at the UC Davis Department of Obstetrics and Gynecology. You will receive the Liletta® IUD and specialty care at no cost, and compensation for your time is available.

Women needed to help us understand what happens when a birth control pill is taken late or a whole day is skipped

You may be eligible to help researchers learn more about the most effective way to use estrogen-free birth control pills!

The purpose of this clinical research study is to understand the effect of a delayed or missed birth control pill. We know that birth control pills are most effective when taken at the same time every day. This study will help us understand more about what happens to the cervical mucus and the ovaries when a progestin-only pill (POP) is taken late or a whole day is skipped. The pill used in this study is Norgestrel, a progestin-only pill (POP). This POP has been marketed in the United States in the past but is not currently approved for use so it is considered experimental. If you're currently not taking a hormonal contraceptive, are unable to become pregnant, or willing to refrain from sexual activity during the course of the study you may be eligible. This clinical research study is conducted at the UC Davis Department of Obstetrics and Gynecology. You will receive all study medication and study evaluations at no cost, and compensation for your time is available.

Drug study, Phase 2
Female, age 18 to 35 years old

HIV Post-Exposure Prophylaxis Uptake and Adherence Post-Sexual Assault

Looking for men and women who have been offered medications to prevent HIV following sexual assault

Thank you for your interest in taking part in the My Experiences Navigating Daily-life (MEND) research study. The purpose of this study is to get information about how and why people do or do not take HIV post-exposure prophylaxis (PEP) (medications to prevent HIV) in the four weeks after a sexual assault. Your participation will involve taking a survey via an internet-based web-application. Completing this survey means you consent to participate in this study.
