Aqua Therapeutics Thermal Therapy Vapor Ablation System (ATTTVAS) Abnormal Uterine Bleeding Safety Study

Abnormal uterine bleeding (AUB) is defined as "flow outside of normal volume, duration, regularity, or frequency". Acute AUB is excessive bleeding that requires immediate intervention to prevent further blood loss. Chronic AUB refers to irregularities in menstrual bleeding for most of the previous 6 months. AUB can be frequent or infrequent, prolonged, irregular, or heavy. Heavy menstrual bleeding (HMB) is defined as "excessive menstrual blood loss which interferes with a woman's physical, social, emotional and/or material quality of life". Causes of AUB are classified as polyps, adenomyosis, leiomyomas (AUB-L), malignancy and premalignant conditions, coagulopathy, ovulatory disorders (AUB-O), endometrial disorders (AUB-E), iatrogenic, and ''not classified'' . AUB affects approximately one in four women between 30 and 50 years of age, with serious implications on woman's quality of life (QoL). Endometrial ablation (EA) is a uterus-preserving procedure that aims to destroy or remove the endometrial tissue in selected women who have no desire for future fertility. EA has become an alternative to hysterectomy in the treatment of AUB because it is less invasive and has a shorter recovery period. At present, many different techniques are available to remove the endometrial tissue. Resectoscopic endometrial ablation (REA) consists of targeted endometrial destruction under direct hysteroscopic visualization. REA techniques include endometrial laser ablation, transcervical resection of the endometrium, and rollerball endometrial ablation. Non-resectoscopic endometrial ablation (NREA) uses a variety of energy sources to non-selectively destroy the endometrial lining and include thermal balloon endometrial ablation, microwave endometrial ablation, hydrothermal ablation, bipolar radiofrequency endometrial ablation, endometrial cryotherapy, and more recently vapor endometrial ablation. NREA technologies require short surgical time and can also be performed in the outpatient setting. Vapor EA is one of the newest approaches in the field. In this context, the Aqua Therapeutics Thermal Therapy Vapor Ablation system (ATTTVAS; AQUA Therapeutics Inc.) is a novel system designed to ablate uterine tissue using vapor thermal therapy technology. The ATTTVAS is indicated to ablate the endometrial lining of the uterus in premenopausal women with abnormal uterine bleeding (AUB) due to benign causes for whom childbearing is complete. In this Pre-Market, First-In-Human, Pilot, Interventional, Clinical Investigation we aim to evaluate the Safety of the Aqua Therapeutics Thermal Therapy Vapor Ablation System (ATTTVAS) in premenopausal women with AUB.

Transdermal Ethinyl Estradiol and Norelgestromin for Irregular Bleeding in Contraceptive Implant Users

The goal of this clinical trial is to evaluate the effectiveness of transdermal contraceptive patches in treating irregular vaginal bleeding in women over 18 years old who are using contraceptive implants and experiencing abnormal vaginal bleeding. The main questions it aims to answer are: * Does transdermal ethinyl estradiol and norelgestromin patch effectively treat irregular vaginal bleeding caused by contraceptive implants compared to placebo? * What proportion of participants will report cessation of vaginal bleeding during treatment and remain bleeding-free at day 14 of treatment? * What is the safety profile and adherence rate of the transdermal patch treatment? Researchers will compare participants receiving active hormonal patches (ethinyl estradiol 600 mcg + norelgestromin 6 mg) to those receiving placebo patches to see if the hormonal treatment effectively stops irregular vaginal bleeding. Participants will: * Apply transdermal patches for 21 days (changing patch every 7 days - total of 3 patches) * Attend follow-up visits at days 7, 14, 21, and 3 months (day 14 in-person, others via telephone) * Complete bleeding diaries and report any side effects * Follow-up schedule: Day 7: Telephone follow-up to assess bleeding pattern, side effects, and patch adherence Day 14: In-person visit at the clinic for comprehensive evaluation including bleeding assessment, side effects monitoring, and adherence check Day 21: Telephone follow-up to evaluate treatment completion, ongoing bleeding status, and need for additional treatment 3 months: Final telephone follow-up to assess long-term outcomes and recurrence of bleeding

Ultrasound Transformation of Myomas During Relugolix-Estradiol-Norethisterone Treatment: The MySaturn Study

Uterine fibroids are benign tumors originating from the uterine muscle, affecting up to 70% of women by their 50s. Risk factors include African descent, nulliparity, obesity, and diabetes. While many fibroids are asymptomatic, 25-50% of affected women experience symptoms like heavy menstrual bleeding, pelvic pain, and pressure-related issues. Accurate diagnosis and differentiation from rare malignant tumors (e.g., uterine sarcomas) remain challenging, particularly before surgery. Ultrasound is the first-line tool for evaluating fibroids, with specific features (e.g., shape, vascularity) helping distinguish benign from suspicious lesions. The MUSA guidelines standardize ultrasound terminology for myometrial assessments. Current treatment options vary based on symptoms and malignancy risk. Among pharmacologic options, the combination of relugolix, estradiol, and norethisterone has shown efficacy in reducing bleeding and pain in symptomatic fibroids, with a favorable safety profile. However, its impact on fibroid morphology and ultrasound appearance is not yet well understood.
