Full Title of Study: “A Phase III Randomised, Double-masked, Parallel Group, Multicentre Study to Compare the Efficacy, Safety, Pharmacokinetics, and Immunogenicity Between SB15 (Proposed Aflibercept Biosimilar) and Eylea® in Subjects With Neovascular Age-related Macular Degeneration”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Treatment
- Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
- Study Primary Completion Date: March 8, 2021
Subjects will be randomised in a 1:1 ratio to receive either SB15 or Eylea® (administered via intravitreal [IVT] injection 2 mg [0.05 mL] every 4 weeks for the first 3 months (i.e., at Weeks 0, 4, and 8), followed by 2 mg [0.05 mL] once every 8 weeks). At Week 32, subjects in Eylea® treatment group will be randomised again in a 1:1 ratio to either continue on Eylea® treatment or be transitioned to SB15 treatment. In the 8-week treatment cycle, IPs (SB15 or Eylea®) will be administered up to Week 48, and the last assessment will be done at Week 56, corresponding to the end of follow-up for all subjects.
- Drug: SB15 (Proposed aflibercept biosimilar)
- Subjects randomized into SB15 group will receive SB15 2 mg (0.05 mL) via intravitreal injection every 4 weeks for the first 3 months, followed by 2 mg (0.05 mL) once every 8 weeks until Week 48. Starting at Week 32, subjects transited from Eylea to SB15 will receive SB15 2 mg (0.05 mL) via intravitreal injection every 8 weeks.
- Drug: Eylea (Aflibercept)
- Subjects randomized into Eylea group will receive Eylea 2 mg (0.05 mL) via intravitreal injection every 4 weeks for the first 3 months, followed by 2 mg (0.05 mL) once every 8 weeks until Week 48.
Arms, Groups and Cohorts
- Experimental: SB15 (Proposed aflibercept biosimilar)
- Subjects randomized into SB15 group will receive SB15 2 mg (0.05 mL) via intravitreal injection every 4 weeks for the first 3 months, followed by 2 mg (0.05 mL) once every 8 weeks until Week 48.
- Active Comparator: Eylea (Aflibercept)
- Subjects randomized into Eylea group will receive Eylea 2 mg (0.05 mL) via intravitreal injection every 4 weeks for the first 3 months, followed by 2 mg (0.05 mL) once every 8 weeks until Week 48. At Week 32, subjects in Eylea group will re-randomized into SB15 or Eylea group. After re-randomization, subjects transited to SB15 group will receive SB15 2 mg (0.05 mL) once every 8 weeks until Week 48 and subjects remaining in Eylea group will continue to receive Eylea 2 mg (0.05 mL) once every 8 weeks until Week 48.
