About this study

The leading risk factor for corneal transplant rejection is abnormal blood vessel growth of the host bed. Vascular endothelial growth factor (VEGF) is thought to be a mediator of this corneal neovascularization (NV), therefore we would like to test the safety and efficacy of local VEGF blockade in the promotion of graft survival in high risk corneal transplants.

Read the detailed description

The purpose of this study is to test the effectiveness of a drug, bevacizumab (Avastin), in preventing blood vessels that often occur after a corneal transplantation which are considered at "high-risk" for rejection. In many cases these blood vessels lead to the graft rejection and eventual failure of the corneal transplant. It is hoped that this treatment will increase the chances of corneal graft survival.

The medication used in this study is called bevacizumab or Avastin (Genentech, Inc). It works by inhibiting the action of a molecule called vascular endothelial growth factor (VEGF). VEGF is a substance molecule that binds to certain cells to stimulate new blood vessel formation. When VEGF is bound to the drug, it cannot stimulate the formation and growth of new blood vessels. Growth of blood vessels into the cornea is a complication which can worsen the prognosis of your corneal transplant and put the transplant at a higher risk for rejection.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Avastin® (bevacizumab)Drug

    Also called Avastin, bevacizumab

    One time subconjunctival injection of 0.1 mL (2.5 mg) bevacizumab followed by topical treatment with 1% solution bevacizumab four times a day for four weeks.

  • 0.9% NaCl & Refresh LiquigelDrug

    Also called Sodium Chloride, Refresh Liquigel, NaCL

Study groups in NCT01072357
Study groupRoleWhat they receive
Avastin® (bevacizumab)Active comparatorTreatment will begin on Day 0, immediately upon the conclusion of the penetrating keratoplasty procedure with an injection of 0.1 milliliter (mL) (2.5 mg) bevacizumab. Starting Day 1 post-transplant surgery, subjects will begin treatment with topical bevacizumab (1% solution). Topical treatment will be self-administered 4 times a day for 4 weeks. The study treatments are to be given in addition to standard of care treatments. Also, all patients will follow a standard post-operative follow-up visit schedule.

Starting Day 1 post-transplant surgery, subjects will begin treatment with topical Refresh Liquigel. Topical treatment will be self-administered 4 times a day for 4 weeks. The study treatments (both topical and subconjunctival injection) are to be given in addition to standard of care treatments. Also, all patients will follow a standard post-operative follow-up visit schedule.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Graft Failure at Week 39 and 52

    Time from surgery to overall graft failure (regardless of cause). Graft failure was monitored throughout the entire study, but only the time points at which graft failure occurred are reported below.

    Measured: 12 months

Secondary outcomes (1)
  1. Endothelial Cell Density

    Endothelial Cell Density (Assessed at Weeks 26 \& 52). Measure of the number of cells present within the endothelium that are responsible for providing the cornea with nourishment.

    Measured: 52 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Avastin® (bevacizumab) and 0.9% NaCl & Refresh Liquigel in people with Corneal Neovascularization and Corneal Graft Failure, run by Reza Dana, MD at 1 site in United States.

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 14 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 15 Jun 2018. 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 United States. 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?

Yes. Results are posted in the registry (first posted 15 May 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Graft Failure at Week 39 and 52 (time frame: 12 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 15 Jun 2018.
