OCL 500 Treatment of Women With Symptomatic Uterine Fibroids

Not Applicable

Completed

• Conditions: Uterine Fibroid; Leiomyoma; Myoma
• Interventions: Device: Occlusin 500 Microspheres

• Registration Number: NCT03427671
• Lead Sponsor: IMBiotechnologies Ltd.

Brief Summary

This is a prospective, open-label, single-arm, safety and effectiveness study of Occlusin 500 microspheres in women with symptomatic uterine fibroids.

Detailed Description

Prior to entering the study, all patients will undergo pre-study assessments including compliance with inclusion and exclusion criteria, laboratory assessments, pelvic examination, and imaging of the pelvis. Following conventional catheter angiography to confirm catheter placement and the uterine vasculature, each patient will undergo transarterial embolization with Occlusin 500 microspheres.
