A study testing Topical Steroids in people with Graft Rejection, run by University of Erlangen-Nürnberg Medical School.
Trial summary
PURPOSE: To assess the impact of duration of topical steroid treatment on the incidence of endothelial graft rejection following normal-risk penetrating keratoplasty (PK).

About this study
Official title: Phase 3: Analysis of a Beneficial Effect of Prolonges Topical Steroid Treatment After Low-risk Penetrating Keratoplasty
PURPOSE: To assess the impact of duration of topical steroid treatment on the incidence of endothelial graft rejection following normal-risk penetrating keratoplasty (PK). DESIGN: Prospective, institutional, longitudinal, randomized interventional trial including 406 eyes (age: 52 >= 19 years; follow-up: 42 >= 18months). METHODS: Postoperative treatment started with prednisolone acetate 1% eye drops five times daily and was tapered over the first 6 months. Patients were then randomised into either short-term (stop topical steroid treatment) or long-term treatment (continue steroids once daily until 12 months).

Questions about this trial
What is this clinical trial studying?
A study testing Topical Steroids in people with Graft Rejection, run by University of Erlangen-Nürnberg Medical School.
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 1 inclusion and 1 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 4 Jun 2015. 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.
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?
Graft survival. 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 4 Jun 2015.
