About this study

Official title: Prospective, Randomized, Double Blind, Multicenter Study for Hyalobarrier ® to Evaluate Anti-adhesive Effect and Safety Compared to Guardix-SG® After Thyroidectomy

This study is a randomized, double-blind, active controlled phase 3 trial in the patients with thyroid disease, who will undergo total thyroidectomy (excluding the patients with the patient with the past history of thyroid surgery).

An eligible patient will be randomized and allocated to either the test group (Hyalobarrier) or active-comparator group (Guardix-SG). He/she will undergo marshmallow esophagography in detecting esophageal dysmotility at 6 weeks after study intervention and will be followed for 12weeks.

During the study, both the patients and the observer for the primary and secondary efficacy evaluation will be masked.

Non-inferiority of the test device (Hyalobarrier) compared to the reference device (Guardix-SG) will be confirmed using the primary efficacy outcome,the percentage of normal esophageal transit.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Hyalobarrier and Guardix-SG in people with Thyroid Disease, run by Green Cross Corporation at 3 sites in South Korea.

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 5 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 28 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in South Korea. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 percentage of normal esophageal transit in marshmallow esophagography (time frame: 6 Weeks after intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Feb 2014.
