July 7, 2014 updated by: Alcon Research

Safety and Efficacy Study of ESBA1008 Versus LUCENTIS® for the Treatment of Exudative Age-Related Macular Degeneration

The purpose of this study was to assess the safety, tolerability, and the effects of treatment on ocular outcomes following a single intravitreal administration of ESBA1008 compared with LUCENTIS® in patients with exudative age-related macular degeneration (AMD).

Study Overview

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

This study was conducted in two parts. In Part 1, patients were initially randomized (5:2) to receive either ESBA1008 at the lowest dose (Dose A) or LUCENTIS. After Safety Committee review, a second cohort was enrolled and randomized (5:2) to the next higher dose of ESBA1008 (Dose B). Safety review and enrollment of patients into the third cohort (Dose C) and fourth cohort (Dose D) was conducted in the same manner. Part 2, the expansion period, consisted of 2 arms. In the first arm patients were randomized to receive ESBA1008 Dose C or LUCENTIS (43:44) . In the second arm, patients were randomized to ESBA1008 Doses A:B:D:Lucentis (5:30:35:9). All enrolled patients (Part 1 and Part 2) were evaluated for safety and efficacy across 13 study visits, including Screening, Randomization, and 11 post- treatment follow-up visits (Day 1 through Month 6).

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.
  • Phase 2
  • Phase 1

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

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Provide written informed consent.
  • Primary subfoveal choroidal neovascularization (CNV) secondary to AMD, including predominantly classic, minimally classic or occult lesions, in the study eye.
  • New diagnosis of wet AMD or evidence of recent disease progression within the last 3 months in study eye.
  • Evidence of subretinal fluid or retinal cystic changes with a CSFT of > 340 μm using a Spectralis SD-OCT (Heidelberg Engineering) imaging system.
  • Best-corrected visual acuity (BCVA) of Snellen equivalent 20/200 or better in the non-study eye.
  • Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

  • Previously administered therapy, approved or investigational, for wet AMD in the study eye.
  • Any current or history of macular or retinal disease in the stuy eye other than wet AMD.
  • Lasik or cataract surgery within the last 3 months in the study eye or expected to have cataract removal surgery during the study.
  • Uncontrolled or advanced glaucoma in the study eye.
  • Use of systemic or topical ocular corticosteroids.
  • History of a medical condition that, in the opinion of the Investigator, would preclude scheduled visits, completion of the study, or safe administration of study medication.
  • Abnormal or unsuitable laboratory results at Screening visit.
  • Lactating or pregnant. Women of childbearing potential must use adequate birth control for the duration of the study.
  • 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
Change From Baseline at Month 1 in Central Subfield Thickness (CSFT) as Measured by Spectral Domain Ocular Coherence Tomography (SD-OCT)
Time Frame: Baseline, Month 1
CSFT is a retinal thickness measurement and was measured with SD-OCT. A thickening of the retina is characteristic of wet AMD, and a reduction in CSFT may indicate an improvement in ocular health. One eye (ie, study eye) contributed to the mean.
Baseline, Month 1

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.
Outcome Measure
Measure Description
Time Frame
Duration of Effect Measured by the Time From Randomization to Receipt of Standard of Care as Determined by the Investigator Based on Protocol Criteria
Time Frame: Time to event, up to Month 6
Standard of care (SOC) therapy for exudative AMD was implemented if any protocol-specified criteria relating to CSFT, best-corrected visual acuity, or clinically significant intraocular hemorrhages in the study eye were met, in the opinion of the Investigator.
Time to event, up to Month 6
