Uterine leiomyomas (fibroids) are the most important neoplastic threat to women’s health worldwide, disproportionately affect women of color and are a significant cause of infertility. Intramural and submucosal fibroids reduce the likelihood of pregnancy (RR=0.3-0.7) compared to unaffected women. Surgical removal of fibroids is afflicted with high recurrence rates and frequent postoperative consequences such as adhesions. There is a critical need for innovative effective, non-hormonal, non-surgical fertility treatment options for women with fibroids that may distort the uterine cavity. Our long-term goal is to develop novel non-hormonal treatments for uterine fibroids. Green tea catechins, such as epigallocatechin gallate (EGCG) is safe during conception and pregnancy. EGCG inhibits key pathways of tumor growth by modulating signaling pathways involved in cell proliferation, transformation, apoptosis and inflammation. Our team evaluated the efficacy and safety of EGCG in women with symptomatic uterine fibroids in a double-blinded, placebo-controlled randomized clinical trial (NCT 01311869). In the placebo group, fibroid volume increased (24.3%); however, patients randomized to EGCG (800 mg/day) showed significant reduction in total fibroid volume (32.6%; P=0.0001). These data indicate that EGCG reduces fibroid size and represents a possible non-hormonal treatment for women with fibroids pursuing pregnancy. The objective of this study is to conduct a randomized clinical trial to determine the effect of EGCG on fibroids and subsequent pregnancy in women seeking fertility treatment. Our central hypothesis is that EGCG will reduce fibroid size and increase the likelihood of pregnancy. To test this hypothesis, we propose a placebo-controlled clinical trial to evaluate live birth outcomes for women with unexplained infertility who have uterine fibroids. Subjects will be randomized to either oral EGCG (800mg/day) vs. placebo for up to 7 months with a 3-month run-in period followed by ovarian stimulation and intrauterine insemination for up to 4 cycles. Aim #1: Will determine the clinical efficacy of EGCG in a randomized study in 654 women pursuing fertility care. Aim #2: Will determine pregnancy outcomes in women seeking fertility care treated with EGCG compared to placebo. Overview of consortium: To meet recruitment goals, the PIs have formed a consortium as described in RFA-HD-19-022. Yale will serve as the data coordinating center and a clinical site, Hopkins will coordinate the single IRB and be a clinical site. Investigators at University of Illinois at Chicago have extensive experience with EGCG and clinical trials and will serve as lead PI. Investigators at the University of Florida have special expertise in clinical trials for fibroids and infertility treatment with prior experience in the Reproductive Medicine Network (AMIGOS, PPCOSII). Each institution has high volume of eligible patients and an excellent fertility center. Impact: Fibroids represent a cause of infertility for millions of affected women and the proposed research could have an immense positive impact on women with uterine fibroids that are seeking fertility care.

子宫肌瘤（肌瘤）是对全世界妇女健康最重要的肿瘤威胁， 不成比例地影响有色人种女性，是壁内和粘膜下不孕的重要原因。 与未受影响的女性相比，子宫肌瘤会降低怀孕的可能性（RR=0.3-0.7）。 肌瘤复发率高，术后后果频繁，例如粘连。 迫切需要创新、有效、非激素、非手术的生育治疗方案 患有可能扭曲子宫腔的子宫肌瘤的女性我们的长期目标是开发新型非激素药物。 绿茶儿茶素，例如表没食子儿茶素没食子酸酯（EGCG）在治疗期间是安全的。 EGCG 通过调节信号通路抑制肿瘤生长的关键通路。 我们的团队评估了其功效和作用。 双盲、安慰剂对照研究中 EGCG 对有症状子宫肌瘤女性的安全性 然而，随机临床试验（NCT 01311869）中，肌瘤体积增加（24.3%）。 随机接受 EGCG（800 毫克/天）治疗的患者显示肌瘤总体积显着减少（32.6%； P=0.0001)。这些数据表明 EGCG 减少了肌瘤的大小并代表了可能的非激素作用。 本研究的目的是进行一项随机试验。 确定 EGCG 对寻求生育的女性子宫肌瘤和随后怀孕的影响的临床试验 我们的中心假设是 EGCG 会减小肌瘤的大小并增加发生的可能性。 为了检验这一假设，我们提出了一项安慰剂对照临床试验来评估活产。 患有子宫肌瘤的不明原因不孕女性的结果将被随机分配到。 口服 EGCG（800 毫克/天）与安慰剂，持续长达 7 个月，并有 3 个月的磨合期，随后进行卵巢治疗 刺激和宫内人工授精最多 4 个周期。目标#1：将确定临床疗效。 EGCG 对 654 名寻求生育护理的女性进行了一项随机研究，目标#2：将决定怀孕。 与安慰剂治疗相比，寻求生育护理的女性的结果： 为了实现招聘目标，PI 成立了一个联盟，如 RFA-HD-19-022 中所述，耶鲁大学将提供服务。 作为数据协调中心和临床中心，霍普金斯大学将协调单个 IRB 并成为临床中心。 伊利诺伊大学芝加哥分校的研究人员在 EGCG 和临床试验方面拥有丰富的经验， 将担任佛罗里达大学的首席研究员，他们在肌瘤临床试验方面拥有特殊的专业知识。 以及具有生殖医学网络（AMIGOS、PPCOSII）经验的不孕不育治疗。 每个机构都有大量符合条件的患者和优秀的生育中心。影响：子宫肌瘤代表。 数百万受影响妇女不孕的一个原因，拟议的研究可能会产生巨大的积极作用 对寻求生育护理的子宫肌瘤女性的影响。
