SOUL Trial Summary
This trial will compare the use of Myfembree to the standard of care in order to see if it can help improve quality of life and delay the need for fibroid surgery.
Who is the study for?
This trial is for premenopausal women aged 18 or older with uterine fibroids confirmed by ultrasound, experiencing heavy menstrual bleeding or pelvic pain. Participants must not be pregnant, have certain medical conditions like osteoporosis or significant cardiovascular disease, and agree to use non-hormonal contraception if sexually active.Check my eligibility
What is being tested?
The SOUL trial is testing whether taking Myfembree orally after surgical myomectomy can delay the return of fibroid symptoms compared to standard care. Myfembree combines relugolix with estradiol and norethindrone acetate and aims to prolong improved quality of life.See study design
What are the potential side effects?
Myfembree may cause side effects such as headaches, hot flashes, increased sweating, muscle pains, tiredness, hair loss, decreased sex drive and acne. It might also affect bone density over time.

Experimental Treatment
Active Control
Group I: Study drug MyfembreeExperimental Treatment1 Intervention
Participants will be asked to take a once-daily tablet of Myfembree ( relugolix 40 mg, estradiol 1 mg, and norethindrone acetate 0.5 mg) for 24 months.
Group II: Parallel group for participants who opt not to be randomizedExperimental Treatment1 Intervention
patients who do not consent to randomization or opt to be in a specific group will be included in a parallel observational study and be administered their preferred treatment.
Group III: Standard of CareActive Control1 Intervention
The standard of care will depend on the participant's type of surgery, health history, and clinical symptoms. It often includes pain management, bleeding management, physical exams, pelvic ultrasound, birth control, and Surgical reintervention.

Side Effect Profile
Prior Approvals
Other Research
Relugolix, a GnRH receptor antagonist, reduces estrogen and progesterone production by inhibiting gonadotropin release, leading to decreased fibroid size and symptoms. Estradiol, an estrogen, mitigates menopausal symptoms caused by reduced hormone levels, while Norethindrone Acetate, a progestin, provides hormonal balance and prevents endometrial hyperplasia.
These treatments are important for fibroid patients as they offer effective symptom management, fibroid size reduction, and improved quality of life without surgery.
