About this study

The goal of this investigator-initiated single-site clinical trial is to compare the overall quality of life of participants taking Relugolix combination therapy (Rel-CT) following excisional surgery for endometriosis to participants that do not take Rel-CT following the same surgery. Rel-CT is an FDA approved form of medical treatment for endometriosis. It is known to work in treating endometriosis pain. However, investigators do not know whether or not there is a benefit to beginning Rel-CT immediately following surgery. This study will test if patients who take Rel-CT after surgery have better quality of life and less chance the endometriosis comes back, requiring additional surgery. The main question it aims to answer is: \- Does taking Rel-CT following excisional surgery for endometriosis result in higher Endometriosis Health Profile 30 (EHP-30) scores, indicating a positive impact on overall health-related quality of life and well-being? Participants will: * Be randomly assigned to one of two treatment groups. One treatment group will take study drug Rel-CT after having excisional surgery, and the other treatment group will just have the surgery alone. * Be asked to complete questionnaires, called the Endometriosis Health Profile 30 (EHP-30) at 4 timepoints. The first time is before surgery, then at follow-up visits at 1 month, 3 months, and 6 months. The survey has 30 questions that ask about pain, control, powerlessness, emotional well-being, social support, and s…

Full eligibility criteria (exactly as the study team wrote them)

Inclusion criteria * Age ≥ 18 years * Planning to undergo an elective laparoscopic or robotic procedure for known or suspected endometriosis Exclusion criteria -A known contraindication to REL-CT. Contraindications include: * High risk of arterial, venous thrombotic, or thromboembolic disorder * Pregnancy Known osteoporosis * Current or history of breast cancer or other hormone-sensitive malignancies * Known hepatic impairment or disease * Undiagnosed abnormal uterine bleeding * Known hypersensitivity to components of Rel-CT * The patient did not discontinue hormonal suppression within the required timeline: Trans-Dermal, Oral Medication, Patch, or Vaginal Ring: day before surgery Intrauterine Device or Sub-Dermal Implant: removed at surgery Injectable Medication: at least 12 weeks before surgery * Primary language other than English/Spanish * Interested in pregnancy within the 6 months following the surgical procedure. * If pregnancy test performed during pre-surgical work up is positive, the patient will no longer be a candidate for endometriosis surgery and will therefore not be eligible for the study. * Patients without histologic evidence of endometriosis following their surgical procedure will be removed from the study prior to receiving the study intervention. * Patients who undergo a surgical intervention more invasive than the planned laparoscopic or robotic excisional surgery, such as open abdominal surgical repair, will be removed from the study prior to receiving the study intervention.
