Abstract
Purpose
Anecortave acetate is a novel angiostatic cortisene being evaluated clinically for treatment of exudative age-related macular degeneration (ARMD). A randomized, placebo-controlled, efficacy and safety dose duration study of anecortave acetate for depot suspension (3 mg, 15 mg, 30 mg) in this patient population was completed in June 2003. As part of this trial, 128 patients with subfoveal choroidal neovascularization (CNV) secondary to ARMD were enrolled and treated for up to 2 years by 18 clinical sites in the United States and European Union.
Methods
Study patients were evaluated clinically with detailed ophthalmic examinations, general physical examinations, assessments of best-corrected logMAR visual acuity, and angiographic evaluations. The Digital Angiography Reading Center (New York City, NY) assessed lesion eligibility while the clinical investigators assessed overall patient eligibility prior to treatment. As part of this study, study medication was delivered as a posterior juxtascleral depot using a specially designed curved cannula at 6-month intervals if in the masked investigator's opinion the patient's lesion could benefit from additional treatment.
Results
The 2-year efficacy results of this placebo-controlled study demonstrated that RE-TAANE 15 mg (anecortave acetate for depot suspension) was statistically superior to placebo for stabilization of vision (<3 logMAR line change from baseline) and for inhibition of neovascular lesion growth. There were no serious treatment-related safety issues associated with either the study medication or the procedure for administration.
Conclusions
Anecortave acetate 15 mg for depot suspension is clinically efficacious compared to placebo for treatment of subfoveal exudative ARMD lesions when administered at 6-month intervals as a posterior juxtascleral depot.
