Clinical Trial Summary

Intrauterine adhesions (IUA) are the major long-term complication of intrauterine procedures and are associated with pelvic pain, menstrual disorders, obstetrical complication and infertility.

Womed Leaf is a medical device specifically designed for intrauterine use that prevents intra-uterine adhesions. It is a film that acts as a mechanical barrier to keep uterus walls separated during healing. It is then naturally discharged through the cervix and vagina in less than 30 days.

The PREG1 clinical investigation is designed to evaluate Womed Leaf safety under clinical conditions, in women scheduled for a hysteroscopic myomectomy as well as its efficacy.

Description:

Intrauterine adhesions (IUA) are defined as "fibrous strings at opposing walls of the uterus and/or cervix leading to partial or complete obliteration of the cavity". IUAs are the major long-term complication of intrauterine procedures and are associated with pelvic pain, menstrual disorders, obstetrical complications and infertility.

Womed Leaf™ is a sterile, degradable polymer film specifically design for intrauterine use. It is inserter in the uterus like an intrauterine device. Once released it will self-deploy into the uterine cavity to form a mechanical barrier keeping uterus walls separated during healing, for several days, thus preventing the formation or recurrence of intrauterine adhesions. It is degraded and discharged naturally through the cervix and vagina in less than 30 days.

The PREG1 clinical investigation is a prospective multicenter, single arm study, designed to evaluate Womed Leaf safety under clinical conditions, in women scheduled for a hysteroscopic myomectomy as well as its efficacy in preventing IUA at second look hysteroscopy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety (Adverse Events)	The number and severity of polymer film related adverse event	30 days
Primary	Efficacy (Rate of Patient With no IUA)	Freedom from intrauterine adhesion	At second look hysteroscopy between 4 and 8 weeks
Primary	Efficacy (Intrauterine Adhesion Severity According to AFS Classification)	Severity of IUAs according to American Fertility Society (AFS) classification systems of adhesions.; Pronostic classification => Hysteroscopy score Stade I (mild) => 1-4 Stade II (moderate) => 5-8 Stade III (severe) => 9-12	At second look hysteroscopy between 4 and 8 weeks
Primary	Efficacy (Intrauterine Adhesion Severity According to ESGE Classification)	Severity of IUAs according to European Society of Gynecological Endoscopy (ESGE) classification systems of adhesions.; I => Thin or filmy IUA easily ruptured by HSC sheath alone. Cornual areas normal II => Singular dense IUA connecting separate parts of the uterine cavity. Visualization of both tubal ostia possible. Cannot be ruptured by HSC sheath alone IIa => Occluding IUA only in the region of the internal cervical os. Upper uterine cavity normal III => Multiple dense IUA connecting separate parts of the uterine cavity. Unilateral obliteration of ostial areas of the tubes IV => Extensive dense IUA with (partial) occlusion of the uterine cavity. Both tubal ostial areas (partially) occluded Va => Extensive endometrial scarring and fibrosis in combination with grade I or grade II IUA with amenorrhea or pronounced hypomenorrhea Vb => Extensive endometrial scarring and fibrosis in combination with grade III or grade IV IUA with amenorrhea	At second look hysteroscopy between 4 and 8 weeks
