Primary Outcome Measures:
  • Cessation of leakage from choroidal neovascularization (CNV) of subjects with late stage AMD

Secondary Outcome Measures:
  • Changes in visual performance

Estimated Enrollment: 27
Study Start Date: December 2004
Estimated Study Completion Date: January 2006
Detailed Description:

This Phase 1 study is a safety and tolerability investigation of LS11 photodynamic therapy in subjects with persistent leaking neovascular membranes in patients with AMD who have a visual acuity of 20/200 or less. This is a sequential group dose escalation trial with the cohorts defined by increasing the light dose. Within each light-dose cohort, three (3) subjects will be treated at a drug dose of 0.2 mg/kg or 0.5 mg/kg.
