Study of Talaporfin Sodium Photodynamic Therapy to Treat Advanced Age Related Macular Disease

March 11, 2010 updated by: Light Sciences LLC

Phase 1 Dose Ranging Study to Evaluate Safety and Tolerability of Talaporfin Sodium (LS11) Photodynamic Therapy in Subjects With Advanced Age-Related Macular Disease

The purpose of this study is to determine the safety and tolerability of Talaporfin Sodium (LS11) Photodynamic Therapy in patients with late stage Age-Related Macular Disease (AMD).

Study Overview

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.
