A Study of Lampalizumab Intravitreal Injections Administered Every Two Weeks or Every Four Weeks to Participants With Geographic Atrophy

Phase 2
Completed
Conditions
Geographic Atrophy
Interventions
Registration Number
NCT02288559
Lead Sponsor
Genentech, Inc.
Brief Summary

This multicenter, randomized, single-masked, sham injection-controlled study will investigate the exposure-response and safety of lampalizumab administered intravitreally every 2 weeks (Q2W) or every 4 weeks (Q4W) for 24 weeks in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). A safety run-in assessment will be conducted prior to initiating enrollment in the randomized study.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Geographic Atrophy (GA) Area, as Assessed by Fundus Autofluorescence (FAF) at Week 24Baseline, Week 24

GA or the death of photoreceptors and surrounding cells in the retina, is a common condition in participants with age-related macular degeneration (AMD). The death of these photoreceptors results in lesions that cause vision loss. The change in GA lesion area was measured by FAF and analysis of FAF images was performed by the central reading center. A positive change from baseline indicates an increase in size of geographic atrophy lesion area (worsening; disease progression). BCVA=best corrected visual acuity; ETDRS=Early Treatment Diabetic Retinopathy Scale.

Secondary Outcome Measures
NameTimeMethod
Serum Concentrations of Lampalizumab (Q2W)Baseline (Day 1, predose and postdose), Weeks 2,4,8,16 and 24, early termination, unscheduled predose and postdose

Lower than reportable (LTR) results on pre-dose sample were set to 0, and LTR results on post-dose sample were set to half of lower limit of quantification (LLOQ) (0.5 nanograms per milliliter (ng/mL)).

Serum Concentrations of Lampalizumab (Q4W)Baseline (Day 1, predose and postdose), Weeks 4,8,16 and 24, early termination

LTR results on pre-dose sample were set to 0, and LTR results on post-dose sample were set to half of LLOQ (0.5 ng/mL).

Percentage of Participants With Anti-Lampalizumab AntibodiesBaseline up to approximately 30 weeks

Having treatment-induced anti-drug antibodies (ADAs) was defined as being ADA-negative at baseline and ADA-positive at any post-baseline timepoint. Having treatment-enhanced ADAs was defined as being ADA-positive at baseline with titer values increased by 0.6 titer units at any post-baseline timepoint.

Percentage of Participants With Ocular Adverse Events (AEs)Baseline up to approximately 30 weeks

An AE was defined as any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether considered related to the medicinal product, any new disease or exacerbation of an existing disease, recurrence of an intermittent medical condition, or any deterioration in a laboratory value or other clinical test. Ocular AEs are the events which are localized in the ocular region.

Percentage of Participants With Systemic (Non-ocular) Adverse EventsBaseline up to approximately 30 weeks

An AE was defined as any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether considered related to the medicinal product, any new disease or exacerbation of an existing disease, recurrence of an intermittent medical condition, or any deterioration in a laboratory value or other clinical test. Non-ocular AEs were the systemic events.
