Endometriosis is a painful disorder of the uterus affecting 6-10% of women of childbearing age. Endometriosis affects daily activities, social relationships, sexuality and sexual activity, and mental health. This study will evaluate how well elagolix in combination with combined oral contraceptives (COC) works within the body and/or how safe it is compared to placebo (does not contain treatment drug). This study will assess the dysmenorrhea (painful periods) response in participants with endometriosis and associated pain. Elagolix is an approved drug for the management of moderate to severe pain associated with endometriosis. Participants are randomly put in 1 of 3 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 3 chance that participants will be assigned to placebo. Adult female participants who still have periods with a diagnosis of endometriosis will be enrolled. Around 800 participants will be enrolled in the study at multiple sites in the United States, including Puerto Rico. Participants will receive oral elagolix or placebo tablets in combination with combined oral contraceptive (COC) or placebo capsules for 3 months. All the participants will receive elagolix tablets in combination with COC tablets from Month 4 through Month 18. There will be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Salsalate for Endometriosis

University Park, Pennsylvania
The purpose of this study is to better understand the underlying mechanisms associated with elevated cardiovascular disease risk in women with endometriosis, and to measure the effectiveness of emerging endometriosis treatments on outcomes specific to cardiovascular dysfunction. Epidemiologic data demonstrate a clear association between endometriosis, reproductive risk factors, inflammation and cardiovascular (CV) risk. Circulating factors, low-density lipoprotein (LDL) and oxidized LDL (oxLDL), are two of many biomarkers of cardiovascular and inflammatory disease of endometriosis. An important signaling mechanism through which circulating LDL and oxLDL act is the lectin-like oxidized LDL receptor (LOX-1). LOX-1 signal transduction functionally results in pronounced endothelial dysfunction, a hallmark of CV. The investigators hypothesis that one factor mediating the elevated risk of cardiovascular disease in endometriosis is systemic inflammation and activation of LOX-1 receptor mechanisms.

Endometriosis, is a condition where tissue from the uterus, called endometrium, grows outside of the uterus. This effects up to 10% of women, and can lead to long-lasting, moderate to severe pelvic pain, infertility and other symptoms. This can affect a woman's quality of life (including increased risk of depression and anxiety) and is associated with increased healthcare costs. Current treatments are often limited by serious side effects, and many women resort to surgery. Surgery is also associated with complications and there are long wait times for procedures, sometimes over 3 years. This means that many women continue to suffer from symptoms while they wait for surgery. Therefore, new effective treatments for endometriosis pain are needed. New research suggests that inflammation and stress caused by lack of oxygen in the affected areas may cause endometriosis. Hyperbaric Oxygen Therapy (HBOT), where patients are placed in a small chamber with higher than normal levels of oxygen, suppresses inflammation and promotes tissue healing. Because inflammation is central to this condition, HBOT has emerged as a potential treatment. In this study, the investigators will test if HBOT, in addition to the standard treatments, is more effective at treating endometriosis pain than the standard treatments alone.

Mindfulness for Endometriosis

Hershey, Pennsylvania
Endometriosis is a common cause of pelvic pain in women which has been historically under-studied and under-diagnosed. The goal of this research is to pilot-test the feasibility and acceptability of a manualized, single-session brief mindfulness-based intervention (BMBI) among participants with endometriosis-related chronic pelvic pain (ECPP) who undergo surgical treatment, and gather preliminary data necessary for future studies assessing BMBI's impact on outcomes in surgically-treated ECPP. This pilot study will enroll 10-20 adult participants with ECPP to receive either a BMBI adjunctive to treatment as usual (TAU; n=5-10) or education with TAU (n=5-10) prior to their ECPP surgery. The central hypothesis is the BMBI is feasible to deliver pre-operatively, acceptable to patients, and may help improve acute post-surgical outcomes through more adaptive stress coping and pain processing, enabled by mindfulness training.

CBD for Endometriosis Pain

Hershey, Pennsylvania
This trial is testing CBD to see if it can help reduce pain and improve the quality of life for patients with endometriosis. The study will compare different doses of CBD over a few months. Researchers believe CBD may work by affecting the body's natural systems that control pain and inflammation. CBD has been shown to significantly improve pain intensity in some studies, although evidence quality is low due to high risk of bias and small sample sizes.

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 self-image. Researchers will compare the two treatment groups (Rel-CT and non Rel-CT) to see if there is a change in EHP-30 scores.

Cabergoline for Endometriosis

Philadelphia, Pennsylvania
This trial is testing cabergoline, a medication that stops new blood vessels from forming, to see if it can reduce pain in adolescents and young women with endometriosis. Current treatments often don't work well or have too many side effects. Cabergoline may offer a safer, long-term solution by preventing the growth of new blood vessels needed for endometriosis to grow. Cabergoline has shown promise in early studies for treating chronic pain due to endometriosis.

The goal of this research is to improve pain outcomes for the over 500K Canadian women, girls and gender-diverse individuals who are newly diagnosed with endometriosis each year. Chronic pain that persists after interventions for endometriosis is a huge problem. There is some evidence that endometriosis-associated pain (EAP) is, at least to some extent, associated with changes in pain physiology, particularly central sensitization of pain. There is currently no effective evidence-informed intervention that addresses EAP. Yet a recent feasibility trial on a repetitive transcranial magnetic stimulation (rTMS) intervention demonstrated promising results compared to a sham intervention for reducing pain in a sample with EAP. The objectives of this trial are: 1. to evaluate the effectiveness of an rTMS intervention for pain reduction among those with recalcitrant post-operative EAP, 2. to inform on the utility of a long (10 session) vs short (5 session) protocol for pain reduction among those with recalcitrant post-operative EAP 3. to determine if any improvements in pain observed 30 days after an rTMS intervention are retained 6 months later 4. to identify physical and psychosocial mediators that impact the successful reduction of pain among patients with EAP treated using rTMS. 5. to describe patients' perceptions of and satisfaction with rTMS as an intervention for EAP.

Frequently Asked Questions

How much do Endometriosis clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Endometriosis clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Endometriosis trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Endometriosis is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Endometriosis medical study ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Endometriosis clinical trials ?

Most recently, we added IUD + Norethindrone Acetate for Endometriosis, TENS for Endometriosis Pain and Hyivy Device for Endometriosis to the Power online platform.
