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

- Arm && Interventions
Group Intervention Description Sham: Randomized Treatment Sham Participants randomized to control arms will receive sham injections, that mimics intravitreal injection of lampalizumab. Lampalizumab: Open-label Safety Run-In Lampalizumab Participants will receive 10 milligrams (mg) lampalizumab intravitreally Q2W during the safety run-in period. Q4W Lampalizumab: Randomized Treatment Lampalizumab Participants will receive 10 mg dose of lampalizumab intravitreally Q4W during the 24-week treatment period. Q2W Lampalizumab: Randomized Treatment Lampalizumab Participants will receive 10 mg dose of lampalizumab intravitreally Q2W during the 24-week treatment period.
- Primary Outcome Measures
Name Time Method Change From Baseline in Geographic Atrophy (GA) Area, as Assessed by Fundus Autofluorescence (FAF) at Week 24 Baseline, 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
Name Time Method 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 Antibodies Baseline 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 Events 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. Non-ocular AEs were the systemic events.
