Brief Summary:
Age-related macular degeneration (AMD) is a disease that, in time, destroys the macula, which is the central part of the retina that gives sharp central vision. The primary purpose of this study is to assess the safety of iSONEP which is a humanized monoclonal antibody against a bioactive lipid, sphingosine 1-phosphate (S1P).

Condition or disease Intervention/treatment Phase
Neovascular Age Related Macular Degeneration Biological: iSONEP Phase 1

Detailed Description:
S1P modulates the AMD-associated processes of angiogenesis, inflammation and fibrosis. A potential strategy for treating choroidal neovascularization associated with AMD is to reduce the biologically available extracellular levels of S1P. iSONEP is highly selective for S1P and binds with picomolar affinity. Lpath proposes that iSONEP would deprive many cell types (fibroblasts, pericytes, vascular endothelial cells and inflammatory) of important growth and survival factors thus targeting the multiple maladaptive processes of exudative AMD that ultimately result in the loss of photoreceptors, their supporting cells, and visual acuity. Targeting simultaneously multiple components of the choroidal neovascular response is a novel approach and has the potential to be more potent than "single-targeted" therapeutics such as anti-VEGF therapies.

Arm Intervention/treatment
Experimental: 1
Biological: iSONEP
single intravitreal injection of 0.2, 0.6, 1.0, 1.4 or 1.8 mg/eye
Other Name: Sonepcizumab; LT1009

Primary Outcome Measures :
  1. To determine safety, tolerability, maximum tolerated dose and dose-limiting toxicity of iSONEP following a single intravitreal injection to subjects with choroidal neovascularization secondary to AMD [ Time Frame: Active phase: 30 days post-injection; Follow-up phase: 12 months post-injection ]

Secondary Outcome Measures :
  1. To characterize systemic pharmacokinetics, evaluate the immunogenicity, and investigate preliminary efficacy on retinal lesion thickness determined by OCT; size and extent of CNV and lesion area; and visual acuity [ Time Frame: Active phase: 30 days post-injection; Follow-up phase: 12 months post-injection ]
