Arm	Intervention/treatment
Experimental: Lampalizumab Once in Every Weeks (Q4W); Participants will receive 10 milligrams (mg) dose of lampalizumab administered by intravitreal injections for approximately 96 weeks.	Drug: Lampalizumab; Participants will receive 10 mg dose of lampalizumab administered intravitreally.; Other Name: RO5490249
Experimental: Lampalizumab Once in Every 6 Weeks (Q6W); Participants will receive 10 mg dose of lampalizumab administered by intravitreal injections for approximately 96 weeks.	Drug: Lampalizumab; Participants will receive 10 mg dose of lampalizumab administered intravitreally.; Other Name: RO5490249
Sham Comparator: Sham Comparator; Participants will receive sham comparator Q4W or Q6W for 96 weeks.	Other: Sham; A sham injection is a procedure that mimics an intravitreal injection of lampalizumab.

11. Change in Functional Reading Independence (FRI) Index [ Time Frame: Baseline to Week 96 ]
12. Percentage of Participants with Ocular Adverse Events [ Time Frame: Baseline up to the end of study (approximately 2 years) ]
13. Percentage of Participants with Systemic (Non-ocular) Adverse Events [ Time Frame: Baseline up to the end of study (approximately 2 years) ]
14. Percentage of Participants with Anti-Lampalizumab Antibodies [ Time Frame: Baseline up to the end of study (approximately 2 years) ]
15. Prognostic Value of the Complement Factor I (CFI) Profile Biomarker Based on the Biomarker Status at Baseline and Change in the GA Area from Baseline as Measured by FAF at Year 1 [ Time Frame: Baseline, Year 1 ]
16. Serum Lampalizumab Concentration [ Time Frame: Baseline to Week 96 ]
