This is an interventional treatment trial for Neovascular Age-related Macular Degeneration

- Patient must be willing and able to comply with the study procedures.
Exclusion Criteria:
- Patient exhibits evidence of retinal angiomatous proliferation in the study eye.
- Patient has retinal-choroidal anastomosis in the study eye.
- Patient has a history of treatment for CNV in the study eye with verteporfin, transpupillary thermotherapy, laser photocoagulation, external beam radiation therapy, or other local treatment (such as submacular surgery).
- Patient has a history of systemic, periocular or intraocular steroid use at any time during the 12 weeks prior to enrollment.
- Patient has a corneal melting, necrotizing keratitis/scleritis, scleritis of an infectious etiology or impending vision loss.
- Patient has a known underlying systemic disease with evidence of a serious or potentially lethal uncontrolled active disease in one or more extraocular organ systems for which a defined effective medical regimen is indicated.
- Patient has active pulmonary tuberculosis or active viral hepatitis.
- Patient has a significant active infection.
- Patient has significant renal or hepatic function impairment greater than mild (grade 2) as per CTCAE v4.0 or hypercholesterolemia uncontrolled by medication and/or diet.
- Pregnant patients or lactating.
- Patient has a history of malignancy within the past two years other than non-melanoma skin cancer.
- Patient has an autoimmune systemic disease requiring immunosuppressive treatment or patient has other medical condition that renders the patient immunocompromised.
- Patient received a live vaccine within past six weeks.
- Patient has significant ocular or periocular inflammation or infection in either eye.
- Patient has the presence of active or inactive toxoplasmosis in the study eye.
Patient is scheduled for surgery during study.

5. Study Description
Brief Summary
The purpose of this study is to evaluate the safety and efficacy of AS101 1% oral solution as compared to placebo in patients with neovascular Age-Related Macular Degeneration (AMD).
AMD Patients who underwent 3 consecutive intravitreal anti VEGF injections and have sub retinal or intraretinal fluid at day 1 of study will be treated orally by AS101 1% solution or placebo once daily for 24 weeks and will be tested for sub retinal or intraretinal fluid every 4 weeks by OCT examination. In case of fluid in macula anti intravitreal anti VEGF injections will be given the same day as needed (PRN). Safety evaluation will be assessed by adverse events related to treatment of 1% AS101 oral solution or placebo. Efficacy will be evaluated in terms of duration of fluid free macula in the AS101 treated group as as compared to placebo treated group;
Detailed Description
A Phase I/II, single-center, randomized double masked placebo controlled study to evaluate the safety and efficacy of AS101 1% oral solution or placebo once daily for 24 weeks in treating patients with neovascular AMD.
Following confirmation of patient eligibility (as detailed in in the inclusion criteria), patients who meet all of the inclusion and exclusion criteria will be enrolled.
On day 1 patients will be randomly allocated to one of the two following study arms in a 1:1 ratio and in a masked manner: (1) AS101 1% oral solution (2) Placebo oral solution. Patients of both study arms will be instructed on how to administer orally the drug at home once daily for 24 weeks. Patients will stop taking the study oral solution at week 24 treatment visit.
In case of existence of fluid in macula, determined as intra retinal or sub-retinal fluid in the macula (as required in inclusion criteria) the standard to care anti-VEGF intravitreal therapy (Lucentis or Avastin, same as the treatment prior to study start) will be injected by a pro re nata (PRN).
Every 4 weeks the investigator will assess if a patient has a fluid free macula based on clinical evaluation, OCT and FA findings In case of fluid in macula the standard of care anti intravitreal anti VEGF injections (Lucentis or Avastin, same as the treatment prior to study start) will be given the same day by a pro re nata (PRN).
The investigator will monitor the occurrence of any adverse event. The study will be completed at week 24 and the study drug, 1% AS101 oral solution or placebo, will be collected from patients.
At week 28 (4 weeks after treatment completion) all patients will be invited for safety assessment.
If the investigator determines that there is a disease progression study therapy is to be discontinued prior to 24 weeks of treatment. Last observation carried forward (LOCF) technique will be used to analyze such patients.
Efficacy will be evaluated in terms of duration of fluid free macula in the AS101 treated group as compared to placebo treated group;
