February 16, 2016 updated by: Peter A Campochiaro, MD

RanibizumabDosE Comparison (0.5mg and 2.0mg) and the Role of LAser in the ManagemenT of REtinal Vein Occlusion - A Pharmacodynamic Approach(RELATE)

The primary Objective of this study is to evaluate the safety and tolerability of intraocular injections of 0.5mg or 2.0mg of ranibizumab in patients with macular edema due to retinal vein occlusion.

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.

Detailed Description

The secondary objectives are to assess the efficacy of 0.5mg versus 2.0mg of monthly ranibizumab injections in patients with macular edema due to retinal vein occlusion between baseline and month 6. At week 24, patients will be re-randomized to receive pro re nata (prn) ranibizumab+laser photocoagulation versus ranibizumab alone and the efficacy of both treatment options will be compared. Treatment efficacy will be assessed by comparing changes in best corrected visual acuity (BCVA) and central subfiled thickness (CST) between the treatment groups.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Signed informed consent and authorization of use and disclosure of protected health information
  • Age equal to or greater than 18 years
  • Diagnosis of macular edema due to central or branch retinal vein occlusion
  • Foveal thickness of equal to or greater than 250 mm, as assessed by OCT
  • Best corrected visual acuity score in the study eye of 20/40 to 20/400 inclusive (Snellen equivalents using the ETDRS protocol at a distance of 4 meters). Only one eye will be treated in the study. If both eyes are eligible, the investigator will select the eye to be enrolled.
  • In the opinion of the investigator, decreased vision in the study eye is due to foveal thickening from vein occlusion and not from other obvious causes of decreased vision

Exclusion Criteria:

  • Scatter laser photocoagulation or macular photocoagulation within 3 months of study entry in the study eye
  • Intraocular surgery in the study eye within 3 months of study entry
  • Use of intraocular or periocular injection of steroids in the study eye (e.g., triamcinolone) within 4 months of study entry
  • Previous use of an anti-VEGF drug within 3 months of study entry
  • Cataract surgery in the study eye within 3 months of study entry; Yttrium-Aluminum-Garnet (YAG) laser capsulotomy within 1 month of study entry; or any other intraocular surgery within 3 months preceding Day 0.
  • History of vitreoretinal surgery in the study eye within 3 months of study entry
  • Uncontrolled glaucoma (defined as intraocular pressure ³30 mm Hg despite treatment with anti-glaucoma medications)
  • History of cerebral vascular accident, myocardial infarction, transient ischemic attacks within 3 months of study enrollment.
  • Pregnancy (positive pregnancy test) or lactation
  • Premenopausal women not using adequate contraception. The following are considered effective means of contraception: surgical sterilization or use of oral contraceptives, barrier contraception with either a condom or diaphragm in conjunction with spermicidal gel, an IUD, or contraceptive hormone implant or patch.
  • Have the presence of active malignancy, including lymphoproliferative disorders. Subjects with a history of fully resolved basal or squamous cell skin cancer may be enrolled.
  • Any condition that the investigator believes would pose a significant hazard to the subject if investigational therapy were initiated.
  • History of allergy to humanized antibodies or any component of the ranibizumab formulation
  • Inability to comply with study or followup procedures
  • Participation in another simultaneous medical investigation or trial
