A Multicenter, Proof-Of-Concept Study Of Intravitreal AL-78898A In Patients With Geographic Atrophy (GA) Associated With Age-Related Macular Degeneration (AMD)

December 3, 2013 updated by: Alcon Research

A Multicenter, Randomized, Single-Masked, Sham-Controlled, Proof-of-Concept Study of Intravitreal AL-78898A in Patients With Bilateral Geographic Atrophy (GA) Associated With Age-Related Macular Degeneration (AMD)

The purpose of this study was to to demonstrate superiority of AL-78898A intravitreal (IVT) injections compared to sham injections by assessing mean geographic atrophy (GA) lesion size change from baseline at Month 12.

Study Overview

Status

Status

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.

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

Participants meeting inclusion/exclusion criteria were randomized in a 2:1 ratio to receive AL-78898A or a sham injection. The study eye was assessed before and after each injection to ensure that the injection procedure and/or study medication had not endangered the health of the eye. The Investigator determined each month whether the patient was eligible to receive the next injection. The study was terminated due to a high likelihood that continued enrollment would reach the predefined study stopping criteria based upon the number of patients with drug deposit formation, which made an assessment of efficacy futile.

Study Type

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

55 years and older (ADULT, OLDER_ADULT)

Genders Eligible for Study

Description

Inclusion Criteria:

  • Ability to provide informed consent and comply with the protocol.
  • Diagnosis of bilateral geographic atrophy (GA) of the macula secondary to age-related macular degeneration, confirmed within 14 days prior to randomization.
  • Study eye: Maximum best-corrected visual acuity (BCVA) of 55 letters (20/80 Snellen equivalent) and a minimum BCVA of 20 letters (20/400 Snellen equivalent) at screening
  • BCVA of 20 letters (20/400 Snellen equivalent) or better in the non treated eye at screening without conditions other than AMD that, in the opinion of the investigator, could cause a rapid loss of vision.
  • Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

  • Any history or current evidence of exudative ("wet") AMD in study eye.
  • Retinal disease other than AMD in the study eye.
  • Any ophthalmologic condition in study eye that reduces the clarity of the media and that, in the opinion of the Investigator interferes with ophthalmologic examination, such as advanced cataract or corneal abnormalities.
  • Any ophthalmologic condition in study eye that prevents adequate imaging of the retina judged by the site or reading center.
  • A history or current medical diagnosis of glaucoma or ocular hypertension in study eye.
  • Any ophthalmic condition in study eye that may require surgery during the study period.
  • Current ocular or periocular infection in the study eye.
  • History of any disease or current use of medication expected to cause systemic or ocular immunosuppression, such as RESTASIS®.
  • History of uveitis or endophthalmitis in the study eye.
  • History of intraocular surgery (including cataract surgery) in the study eye within 90 days prior to dosing.
  • History of intravitreal or periocular injection in the study eye at anytime.
  • Participation in another interventional clinical study, or use of any experimental treatment for AMD or any other investigational new drug within 6 weeks or during active period of drug (whichever is longer) prior to the start of study treatment.
  • History of any medical or psychiatric condition, or substance abuse, that in the Investigator's opinion is likely to interfere with the patient's participation in the study, or likely to cause serious adverse events during the study.
  • Women of child bearing potential UNLESS they are using a highly effective method of birth control.
  • Known or suspected allergy or hypersensitivity to fluorescein or other injectables.
  • Other protocol-defined exclusion criteria may apply.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Change From Baseline in GA Lesion Size at Month 12 as Assessed With FAF Imaging
Time Frame: Day 0 (injection visit), Month 12
Efficacy analysis was not conducted due to the termination of the study prior to the primary and secondary efficacy endpoints and the small number of enrolled patients.
Day 0 (injection visit), Month 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Yearly GA Lesion Size Growth Rate
