MyomaS Aspect Transformation at Ultrasound During Relugolix Estradiol Noretisterone Treatment: MySaturn Study

Observational Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT06953076

This project will see if relugolix‑estradiol‑norethisterone changes the ultrasound appearance of fibroids in premenopausal women with heavy menstrual bleeding.

What this trial studies

MySaturn is a monocentric ambispective observational project enrolling 111 premenopausal women treated with relugolix‑estradiol‑norethisterone and followed for up to 12 months. The study compares retrospective and prospective digital ultrasound images using MUSA-standard terminology to track changes in lesion size, shape, and vascularity. Symptom scores for bleeding and pain and adverse events are recorded alongside imaging. The goal is to characterize whether medical therapy alters ultrasound features that help distinguish benign fibroids from lesions with suspicious characteristics.

Who should consider this trial

Good fit: Ideal candidates are premenopausal women aged 18 or older with symptomatic fibroids causing abnormal uterine bleeding, a myometrial lesion >10 mm on ultrasound, and available digital ultrasound images.

Not a fit: Patients unlikely to benefit include postmenopausal women, asymptomatic individuals, those with lesions ≤10 mm or ultrasound features suggesting malignancy, and people without usable digital ultrasound images.

Why it matters

Potential benefit: If successful, this could help clinicians use ultrasound changes to monitor response to relugolix combination therapy and improve noninvasive risk stratification of uterine lesions.

How similar studies have performed: Previous clinical trials have shown relugolix‑estradiol‑norethisterone reduces bleeding and pain in fibroid patients, but its specific effects on ultrasound morphology have not been well characterized prospectively.
