About this trial

This is an interventional prevention trial for Asherman Syndrome focused on measuring Asherman Syndrome, Intrauterine adhesion, Hysteroscopy, Adhesiolysis, Adhesion prevention, Infertility

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)FemaleDoes not accept healthy volunteers

Inclusion Criteria:

  • Women with moderate or severe intrauterine adhesions according to the AFS classification, i.e AFS score >=5, confirmed by hysteroscopy right before adhesiolysis
  • Scheduled for hysteroscopic adhesiolysis
  • Age above or equal to 18
  • Subjects who are willing to provide a written informed consent.
  • Subjects who can comply with the study follow-up (second look hysteroscopy) and other study requirements

Exclusion Criteria:

Pre-operative criteria

  • Post menopause
  • Abnormal uterine cavity according to ESHRE classification I to V such as unicornis, bicornis, septate, duplex
  • Known or suspected endometrial hyperplasia
  • History of cervical or endometrial cancer
  • Active pelvic infection or history of pelvic peritonitis
  • History of endometrial ablation
  • Known contraindication or hypersensitivity to Womed Leaf component
  • Current participation in another clinical investigation that has not yet received the primary endpoint.

5. Study Description

Brief Summary
PREG2 is a randomized controlled trial that aims to evaluate efficacy in preventing intrauterine adhesion recurrence after hysteroscopic adhesiolysis of a novel intrauterine barrier film named Womed Leaf
Detailed Description
PREG2 is a prospective, multi-center, randomized, controlled, two arm clinical study. The objective is to evaluate the efficacy of Womed Leaf in preventing intrauterine adhesion recurrence after adhesiolysis compared to adhesiolysis alone. The study will be performed on women with moderate or severe adhesions (AFS score >=5) scheduled for adhesiolysis. Indeed, the risk of intrauterine adhesion is very high (up to 60%) in this population of patients. A follow-up diagnostic hysteroscopy will be performed 6-8 weeks after the adhesiolysis procedure to determine the presence and severity of IUAs according to the American Fertility Society and European Society of Gynecologic Endoscopy classification systems of adhesions. Fertility-related outcome will include live pregnancy at 1 year and 2 years and will be reported as secondary endpoints. 154 women are planned to be included in the PREG2 study.

Intervention Type
Device
Intervention Name(s)
Womed Leaf
Intervention Description
Womed Leaf™ device is composed of a uterine anti-adhesion film pre-loaded inside a flexible inserter. Womed Leaf™ is inserted in the uterine cavity by the gynecologist surgeon as a film folded into a 5 mm diameter flexible inserter. Once released, the film will unfold and swell into the uterine cavity to keep uterus walls separated during approximately 5 days. It is degraded and discharged naturally through the cervix and vagina in less than 30 days.
