Evaluation of the Association Between Genetic Load and Response to Anti-VEGF Therapy in AMD Patients (EVERGREEN)

February 11, 2013 updated by: Sequenom, Inc.

Evaluation of Genetic Variants in Patients Under Treatment for Choroidal Neovascular (CNV) Age-related Macular Degeneration (AMD), Receiving Intravitreal Anti-VEGF Injections (Bevacizumab or Ranibizumab) to Evaluate the Association Between Genetic Load and Response to Therapy/Treatment Burden

Patients with AMD who are being or have been treated with eye injections of drugs known as anti-VEGF agents with either good or poor response will have DNA collected with check swabs for analysis.

Study Overview

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The study is designed as a single-center, observational case control evaluation to compare the genetic profiles of two groups of patients categorized according to anti-VEGF treatment response as either "positive" or "suboptimal" responders following treatment with either bevacizumab or ranibizumab anti-VEGF agents. Positive and suboptimal responders will be compared to determine if genetic variant distribution or total genetic load is associated with anti-VEGF treatment response.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

55 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Subject is male or female 55 years of age and older
  • Subject is self-reported as non-Hispanic Caucasian
  • Subject provides a signed and dated informed consent
  • Subject agrees to provide two buccal swabs in accordance with this protocol
  • Diagnosis of CNV secondary to AMD in at least one eye

  • Subject satisfies one of the following:

    1. Has received at least one injection of anti-VEGF therapy (bevacizumab or ranibizumab) with no evidence of residual subretinal or intra-retinal fluid present on SDOCT one month (+/- 1 week) following most recent injection; or
    2. Has received three or more injections in last six months with residual subretinal or intra-retinal fluid present on SDOCT one month (+/- 1 week) following most recent injection, has not shown complete resolution of fluid following any injection in last 6 months, and shows leakage on FA or ICG imaging at some time during last 12 months.

Exclusion Criteria:

  • Previous sample donation under this protocol
  • Presence of retinal disease involving the photoreceptors and/or outer retinal layers other than AMD loss such as high myopia, retinal dystrophies, central serous retinopathy, vein occlusion, diabetic retinopathy and uveitis or similar outer retinal diseases which have been present prior to the age of 50.
  • Opacities of the ocular media, limitations of pupillary dilation or other problems sufficient to preclude adequate imaging of the posterior segment.

Cohorts and Interventions

Group / Cohort

Group / Cohort

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 1, 2012

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
