Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The investigators hope to determine if "wet" AMD patients differ from patients with "dry" AMD or normal eyes in the production of anti-retinal pigment epithelium (anti-RPE) or anti-retinal antibody formation. To explain: the immune system can make antibodies that attack our own cells, specifically the RPE and the retina. Normally the RPE and retinal cells are ignored by the immune system, but when disease occurs, immune reactions can occur, making an autoantibody that can attack the patient's own cells and make things worse. This production of autoantibodies that react with our own RPE and retinal cells is what the investigators want to test in this proposal to see if they may contribute to, or are responsible for, a poor response to treatment. The investigators also want to know how those patients who initially respond to the standard-of-care treatment, ranibizumab injections, differ in the production of anti-RPE or anti-retinal antibody formation, from those patients who do not respond initially after 4 consecutive injections.

Investigators

The overall officials registered on this study. Names that resolve to a findmyKOL profile link to it; the rest are shown as registered.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

United States
  • University of California, Davis

    Sacramento, California, United States

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
