Further study details as provided by Light Sciences LLC:

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.

Ages Eligible for Study:   50 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age 50 or older
  • Subject is able to sign informed consent
  • Ability to complete 6 month trial
  • Present with advanced AMD and persistently leaking CNV
  • Adequate hematologic, renal and liver function
  • Negative pregnancy test
  • Subject is able to safely undertake all protocol directed instructions
  • Visual acuity of 20/200 (logMAR 1.0)(6/60) or worse

Exclusion Criteria:

  • Concomitant eye disease in eye to be treated
  • Prior ocular radionuclide treatments
  • Known allergic or hypersensitivity reactions to light and/or fluorescein and iodine or shellfish
  • History of investigational drug or therapy including biologics within 30 days prior to the study drug dosing
  • Women who are pregnant or lactating, or women of childbearing years not taking adequate contraception precautions
  • History of porphyria, systemic lupus erythematosus, or xeroderma pigmentosum
  • History of clinically significant cardiovascular abnormalities, including myocardial infarction in the past 6 months, uncontrolled arrhythmias, uncontrolled congestive heart failure
  • Concomitant use of other drugs known to produce skin photosensitivity, e.g. tetracycline, sulfonamides, phenothiazines, sulfonylureas, thiazide diuretics and griseofulvin, St. John's Wort
  • Subjects with high or pathological myopia with an axial length > 26mm or a refractive error of >/= -8.00D
  • Subjects with glaucoma and vision loss in either eye
  • Subject with a history of other choroidal leakage, e.g. histoplasmosis
  • Subjects with significant media opacity
  • Subjects diagnosed with diabetic retinopathy
  • Subjects who have had eye surgery within the past 3 months
  • Subjects who have received PDT treatment for AMD in the treatment eye
  • Any disease or condition that the sponsor or the investigator believes will impact the subject's ability to adhere to the study schedule
  • Subjects participating in any concurrent trial
