Official title

Intervention to End Recurrent Unscheduled Bleeding Trial: A Randomized-controlled Trial of Ulipristal Acetate for Unscheduled Bleeding in Etonogestrel Implant Users

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The subdermal etonogestrel (ENG) implant, a long-acting reversible contraceptive (LARC) method, is among the most effective forms of reversible contraception and thus, an important tool in the quest to reduce unintended pregnancy. However, despite overall increases in LARC use in the United States from 1.5% in 2002 to 7.2% in 2011, and 11.6% most recently in 2015, implant use continues to make up a small proportion of LARC use. While evidence to explain this low uptake of implants is lacking, one potential reason is patient and provider concerns about unpredictable bleeding. As a result of this, many studies have been performed in attempts to discover therapies for unscheduled bleeding in progestin-only contraceptive users. Some of these studies include those investigating selective progesterone receptor modulators, such as mifepristone and ulipristal acetate (UPA), which did find some benefit. Although a previous study showed mixed benefit, the investigators feel that this medication has demonstrated both biologic plausibility as well as clinically important outcomes. This previous study may not be entirely translatable to the proposed research as therapies were used for different indications (prophylaxis vs. treatment) and different progestins and delivery systems were studied. Therefore, the investigators believe UPA should not be discounted as a potential therapy. UPA may provide an additional safe and effective option for treatment of irregular bleeding with implants in women. In addition, UPA is currently available in outpatient pharmacies in the U.S. as a single 30mg oral tablet. The investigators propose to investigate UPA for the treatment of unscheduled and troublesome bleeding in ENG implant users.
