About this trial
The aim of this randomized controlled clinical trial is to evaluate the efficacy of green tea (EGCG) and vitamin D3 supplementation in preventing uterine fibroid recurrence following fibroid removal.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Has voluntarily signed and dated the informed consent form before initiation of any screening or study-specific procedures.
Premenopausal females aged 18 years and older on the day of signing of the informed consent form.
Has a diagnosis of uterine fibroids that is confirmed by a pelvic ultrasound (transvaginal and/or transabdominal) performed during the screening period.
Moderate to heavy menses defined as PBAC score ≥ 120
Disqualifiers
Participants with documented vitamin D deficiency (based on previous serum vitamin D level within prior 12 months).
Has transvaginal and/or transabdominal ultrasound during the screening period demonstrating pathology other than uterine fibroids that could be responsible for or contributing to the patient's heavy menstrual bleeding, such as uterine or cervical polyps > 2.0 cm, or any other clinically significant gynecological disorder determined by the investigator to require further evaluation and/or treatment.
Has unexplained vaginal bleeding outside of the patient's regular menstrual cycle.
Has undergone ultrasound-guided laparoscopic radiofrequency ablation, or any other surgical procedure for fibroids, uterine artery embolization, magnetic resonance-guided focused ultrasound for fibroids, as well as endometrial ablation for abnormal uterine bleeding within 6 months prior to the screening visit.

Trial outcomes
Primary outcomes
Fibroid Recurrence
The primary outcome is: Fibroid recurrence when compared to the post-myomectomy baseline pelvic ultrasound (transvaginal and/or transabdominal), defined as a new fibroid identified on ultrasound with volume \>1 cm3.
Secondary outcomes
Return of moderate to heavy menses
Return of moderate to heavy menses defined as PBAC score ≥ 120 for patients with pre-operative moderate to heavy menses. PBAC stands for Pictorial Blood Loss Assessment Chart. In this chart, there is no unit. In this Chart, the higher the number, the heavier the menses.
Need for reintervention
Need for reintervention defined as the need to undergo a procedure or surgery for treatment of uterine fibroids including repeat myomectomy, uterine fibroid embolization, and radiofrequency ablation. In this outcome, we will examine the participant info at each evaluation visit to capture the data if she has undergone any anti-fibroid procedure or surgery. The captured data will be: "Yes" or "No".
Time to event
Time to event (procedure or surgery) such as radiofrequency ablation (RFA), myomectomy, hysterectomy, or uterine fibroid embolization (UFE). The unit for this outcome is "weeks". In this outcome, we will examine the patient info at each evaluation visit to calculate the number of "weeks" it took a participant to need to undergo an anti-fibroid procedure or surgery.
Symptom recurrence
Symptom recurrence according to the Uterine fibroid quality of life symptoms severity subscale. There is no unit for this outcome. Higher score values are indicative of greater symptom severity and lower scores will indicate minimal symptom severity.
