Study of Bimonthly VEGF Trap-Eye Compared to As-needed Administration or Other Therapy for Exudative Age-Related Macular Degeneration

November 17, 2014 updated by: Theodore Leng, Stanford University

Bimonthly VEGF Trap-Eye Compared to As-needed Administration or Standard Therapy for Exudative Age-Related Macular Degeneration

Over the last several years, the standard of care for wet macular degeneration has become treatment with intravitreal injections of ranibizumab (Lucentis, Genentech), administered as frequently as every 4 weeks. In contrast, clinical trials of a soluble VEGF receptor, Aflibercept/VEGF Trap-Eye (Eylea, Regeneron Pharmaceuticals) have demonstrated maintained anatomic and visual improvement with many fewer injections (typically monthly injections for 3 months, followed by every-other-month injections, and as few as 5 injections a year). The purpose of this study is to determine whether patients who have switched from ranibizumab to VEGF Trap-Eye have comparable results.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Sampling Method

Non-Probability Sample

Study Population

Patients with exudative age-related macular degeneration

Description

Inclusion Criteria:

  1. Patients older than the age of 50 determined by a retinal physician at the Byers Eye Institute at Stanford to have exudative AMD requiring treatment.
  2. Patients with an established diagnosis of exudative AMD who have been maintained on a regimen of intravitreal ranibizumab injections.
  3. Postmenopausal or negative pregnancy test
  4. Patients with an established diagnois of exidative AMD who have been switched from intravitreal ranibizumab to intravitreal VEGF Trap-EYE.

Exclusion Criteria:

  1. Patients with any previous or concurrent history of treatment of other retinal diseases with pharmacologic agents other than ranibizumab, including verteporfin photodynamic therapy, bevacizumab, triamcinolone, or dexamethasone.
  2. Patients with prior history of vitrectomy surgery in the study eye.
  3. Patients enrolled in any previous or current clinical trial or study of any medication for AMD or any other retinal vascular disease, including diabetic retinopathy or retinal vein occlusion.
  4. Ocular media opacity precluding proper retinal imaging
  5. Inadequate pupillary dilation to achieve proper retinal imaging
  6. Concurrent use of systemic anti-VEGF agents
  7. CNV due to other causes, including histoplasmosis, uveitis, trauma, or myopia
  8. Active or recent (< 4 weeks) or recurrent inflammation in the eye
  9. Current vitreous hemorrhage in the study eye limiting visualization of the fundus
  10. Active infectious conjunctivitis, keratitis, scleritis, or endophthalmitis
  11. Untreated glaucoma with IOP > 25 in the eye
  12. Other ocular diseases that can compromise the visual acuity of the study eye such as amblyopia and anterior ischemic optic neuropathy
  13. Pregnancy or lactation
  14. History of other disease, exam finding, or clinical laboratory that contraindicates the use the drug
  15. Current treatment for active systemic infection
  16. Evidence of significant uncontrolled concomitant diseases such as cardiovascular disease, pulmonary, renal, hepatic, endocrine, or GI disorders
  17. History of recurrent significant infections or bacterial infections
  18. Inability to comply with study or follow-up procedure

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.
January 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.
