Trial summary

Human serum eye drops have been successfully used in the treatment of severe ocular surface disorders and the enhancement of corneal wound healing. Umbilical cord serum is also proven to be effective in treatment of dry eye and persistent corneal epithelial defects. Read more about this study

About this study

Official title: Phase 1 Study of Comparison of the Effects on Promoting Corneal Epithelial Wound Healing Between Human Autoserum and Cord Blood Serum-in Vitro Cell Culture Experiment

Human serum eye drops have been successfully used in the treatment of severe ocular surface disorders and the enhancement of corneal wound healing. Umbilical cord serum is also proven to be effective in treatment of dry eye and persistent corneal epithelial defects. However, there are limited studies comparing the corneal epithelial wound healing promoting effects between these two blood derived products. The purpose of this study is to test the corneal epithelial wound healing promoting effects between auto serum and human cord blood serum. Primary cultured bovine corneal epithelial cells were used as the model to investigate wound healing, cell proliferation and migration by means of scratch corneal wound healing assay evaluation, MTS assay and Boyden chamber migration assay in response to human serum and umbilical cord serum. The concentrations of EGF, TGF-β1, and fibronectin were also compared between human serum and umbilical cord serum with ELISA kits.

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 4 inclusion and 2 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 10 Jan 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. 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.

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?

Cell proliferation (time frame: 1 week). 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 NCT00681642, which also lists 13 linked publications.

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 10 Jan 2011.
