An Extension Study to Evaluate the Long-Term Safety of Lampalizumab in Participants With Geographic Atrophy

Study Overview
=================
Brief Summary
-----------------
This is a multicenter, open-label extension study of safety and tolerability of lampalizumab administered by intravitreal (ITV) injection to participants with geographic atrophy (GA) who have completed the 18-month treatment in Study CFD4870g (GX01456) (NCT01229215) or 24-week treatment in Study GX29455 (NCT02288559).

Official Title
-----------------
A Multicenter, Open-Label Extension Study to Evaluate the Long-Term Safety and Tolerability of Lampalizumab (FCFD4514S) in Patients With Geographic Atrophy Who Have Completed Genentech-Sponsored Lampalizumab Studies

Conditions
-----------------
Geographic Atrophy

Intervention / Treatment
-----------------
* Drug: Lampalizumab


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: For CFD4870g participants: Previous enrollment and completion (Month 18 visit) of Study CFD4870g without early treatment discontinuation (lampalizumab or sham) For GX29455 participants: Previous enrollment and completion (Week 24 visit) of Study GX29455 without early treatment discontinuation (lampalizumab or sham) Sufficiently clear ocular media, adequate pupillary dilation, and fixation to permit quality fundus imaging Exclusion Criteria: Early treatment and/or study discontinuation prior to completion of study CFD4870g (GX01456) and GX29455 Vitrectomy surgery, submacular surgery, or other surgical intervention for age-related macular degeneration (AMD) in the study eye Subfoveal focal laser photocoagulation in the study eye Treatment with Visodyne, external-beam radiation therapy, or transpupillary thermotherapy in the study eye Intravitreally (ITV) drug delivery (e.g., ITV corticosteroid injection, anti-angiogenic drugs, anticomplement drugs, or device implantation) in the study eye. Lampalizumab in study eye and ranibizumab in either eye are permitted Any concurrent ocular or intraocular condition in the study eye that contraindicates the use of an investigational drug or may affect interpretation of the study results or may render the participant at high risk for treatment complications

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Ocular and Non-ocular Adverse Events (AEs) | 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 events localized to the eye. Non-ocular events include all other events. | From Day 1 up to the last study visit (up to approximately 62 months) |
