About this study

Official title: The Efficacy and Safety of a New Cross-linked Hyaluronan Hydrogel in the Reduction of Postsurgical Adhesions After Laparoscopic Gynecological Surgery: a Randomized Controlled Trial

The purpose of this study was to determine whether the new crosslinked hyaluronan hydrogel was safe to use, and was effective for the prevention/reduction of adhesion formation following gynecological surgery

Read the detailed description

Postsurgical adhesions are a common medical complication of gynecologic and pelvic surgeries, and are frequently associated with chronic or recurrent pelvic pain, intestinal obstruction and infertility. This randomized, controlled, multicenter, clinical study was designed to evaluate the safety and performance of the new crosslinked hyaluronan hydrogel versus the standard of care for the reduction of postoperative adhesions in subjects undergoing laparoscopic surgeries. Subjects were scheduled to return at 9 weeks after the initial surgical procedure. At that time, a second-look laparoscopy was performed for postsurgical adhesion assessment. Adhesions were graded using a modified American Fertility Society (mAFS) scoring system.

    Measured: 9 weeks following primary laparoscopic gynecological surgery

  3. Adhesion severity

    Adhesion severity of ovaries/tubes

    Measured: 9 weeks following primary laparoscopic gynecological surgery

  4. The adhesion incidence under moderate/severe category

    The patient percentage with modified American Fertility Society (mAFS) score (throughout abdominopelvic cavity) more than 4 points.

    Measured: 9 weeks following primary laparoscopic gynecological surgery

  5. modified American Fertility Society (mAFS) score

    modified American Fertility Society (mAFS) score (throughout abdominopelvic cavity)

    Measured: 9 weeks following primary laparoscopic gynecological surgery

  6. Adhesion extent

    Adhesion extent (throughout abdominopelvic cavity)

    Measured: 9 weeks following primary laparoscopic gynecological surgery

  7. Adhesion severity

    Adhesion severity (throughout abdominopelvic cavity)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Saline and Cross-linked Hyaluronan Hydrogel in people with Myomas and Ovary Cysts, run by BioRegen Biomedical (Changzhou) Co., Ltd at 7 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jun 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The adhesion incidence under moderate/severe category (time frame: 9 weeks following primary laparoscopic gynecological surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02166554, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2014.
