Detailed Description
This is a phase I/II open label, randomized, interventional clinical trial. Study eyes will receive one preoperative intravitreal aflibercept injection (IAI) <21 days but >7 days prior to vitrectomy and one intraoperative intravitreal aflibercept at end of surgery followed by randomization in a 1:1 ratio into either 4 mandatory postoperative q4weeks IAI followed by mandatory q8 weeks IAI for 52 weeks follow-up (q8 week Group) or 2 mandatory postoperative q4weeks IAI followed by mandatory q16 weeks IAI for 52 weeks follow-up (q16 week Group).
Follow-up visits occur 1 day and 1-2 weeks, and 4 weeks postoperatively and then every 4 weeks from the first postoperative IAI for 52 weeks. One preoperative visit and every postoperative visit (except day one postoperatively) will include ETDRS Best Corrected Visual Acuity (BCVA), Intraocular Pressure (IOP) measurement, Slit lamp biomicroscopy, Indirect ophthalmoscopy, Heidelberg Spectralis Spectral Domain Optical Coherence Tomography (SD-OCT) (no OCT for preoperative visit) and evaluation for systemic and ocular adverse events. Seven standard field photographs and Optos wide-field fluorescein angiography will be performed at postoperative visits at 4, 16, 28, 40,and 52 weeks. Humphrey visual field (HVF) testing (30-2 and 60-4 test patterns) will be performed at postoperative visits at 4 and 52 weeks. Preoperative B scan echography will be required standard of care(SOC) to assess for macular traction, non-macular traction, retinal detachment and vitreous hemorrhage(VH). Identification of traction macular detachment will exclude the patient from the study.

Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: IAI q8 week Group
Eyes will be randomized on the day of endolaserless vitrectomy surgery or first postoperative 1-2 week visit to a group ("q8 week Group") where 4 additional mandatory postoperative q4weeks IAI followed by mandatory q8 weeks IAI for 52 weeks follow-up.
Starting at week 20 in the q8week group eyes may be eligible to receive additional 2mg IAI (intravitreal aflibercept) (monthly) treatment
|
. Study eyes will receive one preoperative intravitreal aflibercept injection (IAI) <21 days prior to vitrectomy and one intraoperative intravitreal aflibercept at end of surgery.
Eyes will be randomized on the day of surgery or 1-2 weeks post-operatively to either a q8week IAI dosing regimen group or a q16week IAI dosing regimen group.

ACTIVE_COMPARATOR: IAI q16 week Group
Eyes will be randomized on the day of endolaserless vitrectomy surgery or first postoperative 1-2 week visit to a group (q16week Group) where 2 additional mandatory postoperative q4weeks IAI will be followed by mandatory q16weeks IAI for 52 weeks follow-up.
Starting at week 12 in the q16 group, eyes may be eligible to receive additional 2mg IAI (intravitreal aflibercept) (monthly) treatment.
