About this trial

This is an interventional prevention trial for Infertility focused on measuring Infertility, Reproductive outcome, Hysteroscopy, Adhesion prophylaxis

Eligibility Criteria

18 Years - 47 Years (Adult)FemaleDoes not accept healthy volunteers

Inclusion Criteria:

Women aged 18 to 47 years attending Belgian fertility clinics, scheduled for operative hysteroscopy for endometrial polyps, fibroids with uterine cavity deformation, uterine septa, intrauterine adhesions (IUAs) and retained products of conception, and wishing to conceive spontaneously or before fertility treatment with ovulation induction (OI), controlled ovarian stimulation (COS), intrauterine insemination (IUI) or IVF/ICSI.

Exclusion Criteria:

  • Women younger than 18 years
  • Women 48 years of age or older
  • Women with a known allergy to HYALOBARRIER® GEL ENDO
  • Women with an active infection of the genital tract proven by genital swabs for PCR (Chlamydia, gonococci) or endometrial biopsy (endometritis), not treated at the time of the pre- screening visit. Women adequately treated with proven cure (negative swabs or normal endometrial biopsy) can be included
  • Subserosal fibroids (FIGO or PALM-COEIN classification type 6, 7) - leiomyomas that originate from the myometrium at the serosa of the uterus or intramural fibroids without uterine cavity deformation as documented by ultrasound, hysterography or hysteroscopy - as the sole uterine cavity abnormality identified in the screening phase.
  • Women with fibroids, polyps, uterine septa or IUAs suffering from other symptoms, for instance abnormal uterine bleeding, but not wishing to conceive from 6 weeks following surgery
  • Women with other Müllerian tract anomalies other than a uterine septum as the sole uterine cavity abnormality identified in the screening phase
  • Women who participated in the trial but failed to conceive and who present with a recurrence of polyps, fibroids with cavity deformation, uterine septum or IUAs

5. Study Description

Brief Summary
To compare the costs and effects of HYALOBARRIER® GEL ENDO versus no HYALOBARRIER® GEL ENDO for increasing the chance of conception leading to live birth measured at 30 weeks after randomization in women wishing to become pregnant after surgical removal of intrauterine pathology (endometrial polyps, fibroids with uterine cavity deformation, uterine septa, IUAs or RPOC after miscarriage) by hysteroscopy as an outpatient or in hospital treatment.
Detailed Description
Design: Multi-centre, parallel group, superiority, double-blind, randomized controlled trial. Post market study of a Medical Device class III. Participant: Women aged 18 to 47 years attending Belgian gynaecological departments, scheduled for operative hysteroscopy for endometrial polyps, fibroids with uterine cavity deformation, uterine septa, intrauterine adhesions (IUAs) or retained products of conception, and wishing to conceive spontaneously or before fertility treatment with ovulation induction (OI), controlled ovarian stimulation (COS), intrauterine insemination (IUI) or IVF/ICSI. Treatment: Application of Hyalobarrier® gel endo at time of surgery Control: No application of Hyalobarrier® gel endo Follow up: short term follow-up: 30 weeks after receiving the treatment allocation long term follow-up: 66 weeks after receiving the treatment allocation To blind all trial participants, fertility physicians and gynaecologists doing second- or third-look hysteroscopy, 10 ml of a sterile ultrasound gel will be applied into the vagina at the end of the procedure in all women regardless of their treatment allocation.

ParticipantCare ProviderInvestigator
Masking Description
None of the participants will be informed of the allocated treatment by the surgeon performing the operative hysteroscopy or the personnel present in the OR. The medical record will not reveal any information whether HYALOBARRIER® GEL ENDO was applied at the end of the procedure. The REDCap software will automatically document the allocation and store all the records and the randomisations. The gynaecologist doing the operative hysteroscopy should not be the same as the fertility physician and the gynaecologist doing the second look hysteroscopy. In the exceptional case that the surgeon doing the operative hysteroscopy is the same person as the fertility physician or the gynaecologist doing the second-look hysteroscopy, blinding is assured by notification of treatment allocation if the surgeon has left the operating room.
