About this study

The purpose of this study is to investigate the safety and efficacy of human conjunctival epithelial autologous cultivated ex vivo for reconstruction of the ocular surface in patients with symblepharon.

Read the detailed description

10 patients will be included from 16 to 90 years with presence of symblepharon, what have been already subjected to proceedings of reconstruction of the ocular surface without success and to present conjunctival healthy. In the place of biopsy and after the surgery of the patient one will be applied ointment with antibiotic and corticoid to minimize the inflammatory effects. The fragments will be transported even it laboratory of Molecular Biology of the advanced Centre of Ocular Surface where it will be prosecuted by means of technique sterile under laminating flow. The conjunctival epithelias cells will be put on the amniotic membrane compartments of the plate of culture where the appropriate ways will be added. After 2 weeks the membranes colonized with epithelium conjunctival they will be subjected to the coloration and the cloth will be used for the surgery of reconstruction of the ocular surface. It will be carried out first us an evaluation ophthalmologic complete weekly, 2 months and then fortnightly up to the sixth month post-operative.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Autologous Ex Vivo Conjunctival for Symblepharon Transplantation and Ex Vivo Conjunctival for Symblepharon Transplantation in people with Symblepharon, run by Federal University of São Paulo.

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 8 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: status not confirmed, as of the sponsor's last update on 1 Dec 2008. Status can change between updates, so confirm with the study contact before making plans.

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 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.

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

Are results available for this study?

Results are not available in the source record.

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?

Reconstruction of Ocular surface in patients with symblepharon (time frame: 6 months). 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 1 Dec 2008.
