Description of intervention(s) / exposure
Treatment: Drugs - Brolucizumab
Treatment: Drugs - Aflibercept

Experimental: Brolucizumab 3 mg - Brolucizumab 3 mg/0.05 mL, 5 loading doses, with subsequent doses per protocol-specified maintenance schedule.

To fulfil the double-masking requirement, each investigational site had masked and unmasked staff. The investigator who performed the injection was unmasked to the treatments as were any other site personnel who had been delegated responsibility for working with the Investigational Product (IP).

Experimental: Brolucizumab 6 mg - Brolucizumab 6 mg/0.05 mL, 5 loading doses, with subsequent doses per protocol-specified maintenance schedule.

To fulfil the double-masking requirement, each investigational site had masked and unmasked staff. The investigator who performed the injection was unmasked to the treatments as were any other site personnel who had been delegated responsibility for working with the Investigational Product (IP).

Active comparator: Aflibercept 2 mg - Aflibercept 2 mg/0.05 mL, as labeled, 5 loading doses, with subsequent doses every 8 weeks.

To fulfil the double-masking requirement, each investigational site had masked and unmasked staff. The investigator who performed the injection was unmasked to the treatments as were any other site personnel who had been delegated responsibility for working with the Investigational Product (IP).
