First set of inclusion criteria:
All of the following criteria must have been met at the initial start of aflibercept treatment (i.e. start of aflibercept treatment prior to this study):
1. Subject had primary subfoveal choroidal neovascularization (CNV) lesions secondary to nAMD, including juxtafoveal lesions that affect the fovea, as evidenced by FA of the study eye within 4 weeks before the initiation of aflibercept treatment.
2. The area of CNV occupied at least 50% of the total lesion within 4 weeks before the initiation of aflibercept treatment.
3. Documented BCVA was 20/40 to 20/320 (comparable to a letter score of 73 to 25) in the study eye at the initiation of treatment (the initial BCVA of the study eye before treatment initiation must be documented as Snellen equivalent in the electronic case report form [eCRF]).
Second set of inclusion criteria:
All of the following criteria must be met at the time of screening for participation in this study for a subject to be eligible for this study.
4. Signed written informed consent
5. Men and women = 51 years of age
6. The subject’s history of aflibercept treatment meets ALL of the following:
a) Treatment in the study eye was initiated with three monthly (-1 week/+2 weeks) doses of 2 mg aflibercept and improvements of visual and anatomic outcomes were observed
b) Following the above initiation phase, the intervals between treatments were between 6 weeks and 12 weeks (one exception will be allowed)
c) The interval between the last two pre-study injections was = 8 weeks, and visual and anatomic outcomes have been stable over this interval.
d) The subject received the last IVT injection of aflibercept in the study eye 2 months (±10 days) before the first treatment in this study
e) Total prior treatment duration with aflibercept (i.e. from first treatment to randomization into this study) was = 12 months
7. Subject is willing, committed, and able to return for ALL clinic visits and complete all study-related procedures.
8. Women and men of reproductive potential must agree to a method of highly effective contraception (as defined by the Clinical Trial Facilitation Group [CTFG] from 15 SEP 2014):
• Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation:
o oral
o intravaginal
o transdermal
• Progestogen-only hormonal contraception associated with inhibition of ovulation:
o oral
o injectable
o implantable
• Intrauterine device
• Intrauterine hormone-releasing system
• Bilateral tubal occlusion
• Vasectomized partner
• Sexual abstinence
Alternatively women and men of reproductive potential can also use two acceptable methods of contraception (as defined by the CTFG from 15 SEP 2014) simultaneously:
• Progestogen-only oral hormonal contraception, where inhibition of ovulation is not the primary mode of action
• Male or female condom with or without spermicide
• Cap, diaphragm or sponge with spermicide
First set of exclusion criteria:
A subject who has met any of the following criteria at the initial start of aflibercept treatment (i.e. start of aflibercept treatment before this study) will be excluded from this study.
1. Any prior or concomitant therapy with an investigational or approved agent to treat neovascular AMD in the study eye.
2. Total lesion size > 12 disc areas (30.5 mm2, including blood, scars and neovascularization) as assessed by FA in the study eye
3. Subretinal hemorrhage that was:
a) 50% or more of the total lesion area, or
b) if the blood was under the fovea, and
c) the blood under the fovea was 1 or more disc areas in size in the study eye.
4. Scar or fibrosis making up more than 50% of the total lesion in the study eye.
5. Scar, fibrosis, or atrophy involving the center of the fovea in the study eye.
6. Presence of retinal pigment epithelial tears or rips involving the macula in the study eye.
7. Causes of CNV other than AMD in the study eye.
Second set of exclusion criteria:
A subject who meets any of the following criteria at the time of screening for participation in this study will be excluded from this study.
8. Subjects who currently meet any of the first set of exclusion criteria with the exception of prior treatment with aflibercept
9. Any prior ocular (in the study eye) or systemic treatment or surgery for neovascular AMD, except dietary supplements, vitamins and IVT injections of aflibercept, during the time (i.e. at least 12 months) between initiation of aflibercept treatment and randomization into this study
10. Any prior treatment with anti-VEGF therapy in the study eye, with the exception of IVT injections of aflibercept, during the time (i.e. at least 12 months) between initiation of aflibercept treatment and randomization into this study
11. Prior systemic anti-VEGF therapy, investigational or approved, within the last 15 months prior to randomization
12. Any vitreous hemorrhage within 4 weeks before randomization in the study eye
13. Active intraocular, extraocular and periocular inflammation or infection in either eye.
14. Any ocular or periocular infection within 4 weeks of randomization in either eye
15. Any serious adverse event related to aflibercept during prior treatment
16. Any history of allergy or hypersensitivity to povidone iodine.
17. Known serious allergy or hypersensitivity to the fluorescein sodium for injection in angiography
18. Presence of any contraindications indicated in the EU commission/locally approved label for aflibercept: Hypersensitivity to the active substance aflibercept or to any of the excipients; active or suspected ocular or periocular infection; active severe intraocular inflammation
19. Prior vitrectomy in the study eye
20. History of vitreomacular traction in the study eye
21. History of retinal detachment or treatment or surgery for retinal detachment in the study eye.
22. Any history of macular hole of stage 2 and above in the study eye
23. Prior trabeculectomy or other filtration s
