Beskrivelse
Inclusion Criteria:
Note: Subjects must meet all of the following inclusion criteria to be eligible for enrollment into the study
- Age >50 years
- Active primary subfoveal choroidal neovascularization (CNV) lesions secondary to AMD including juxtafoveal lesions that affect the fovea as evidenced by Fluorescein Angiography in the study eye
- Presence of intra or sub retinal fluid on SDOCT in the study eye
- Current treatment with uninterrupted routine (q35 +/- 7 days) ranibizumab started at least 3 months before Baseline (Week 0), having received at least 3 consecutive ranibizumab injections and no more than 24 injections maximum, with all ranibizumab injection intervals being 35 +/- 7 days apart
- ETDRS BCVA 20/30 and 20/320 (letter score of 78 to 25) in the study eye
Exclusion Criteria:
Subjects presenting with any of the following will not be included in the study:
- Presence of purely serous pigment epithelial detachment in the study eye
- Any scarring or fibrosis involving the center of the fovea in the study eye
- Prior ocular or systemic treatment/surgery for wet AMD other than ranibizumab IVI monthly (in study the eye)
- Prior prn or treat and extend treatment with ranibizumab IVI between 3 to 24 months before Baseline (Week 0) in the study eye
- Prior treatment with systemic anti-VEGF therapy within the last 6 months in the study eye
- History of vitreous hemorrhage within the last 6 months in the study eye

- History of retinal detachment in the study eye
- History of macular hole of stage 2 and above in the study eye
- Presence of retinal pigment epithelial tears or rips involving the macula in the study eye.
- Any intraocular or periocular surgery/invasive procedure during the previous 6 months except lid surgery in the study eye
- Prior trabeculectomy or other filtration surgery in the study eye
- Uncontrolled glaucoma (≥ 25mmHg despite treatment with anti-glaucoma medications) in the study eye
- Aphakia or pseudophakia with absence of posterior capsule (unless it occurred as a result of a yttrium aluminum garnet (YAG) posterior capsulotomy) in the study eye.
- Scheduled for intraocular surgery during the study period in the study eye
