Anecortave acetate for the treatment of exudative age-related macular degeneration--a review of clinical outcomes.

PURPOSE: The angiostatic cortisene anecortave acetate was evaluated in three safety and efficacy studies of patients with subfoveal choroidal neovascularization secondary to exudative age-related macular degeneration. METHODS: The Anecortave Acetate Monotherapy Trial enrolled 128 patients randomized to anecortave acetate (3 mg, 15 mg, or 30 mg) or vehicle administered as a sub-Tenon's posterior juxtascleral depot (PJD) at 6-month intervals. The Anecortave Acetate and photodynamic therapy (PDT) with verteporfin Combination Trial enrolled 136 patients randomized to PDT with verteporfin followed by a single depot administration of anecortave acetate (15 mg or 30 mg) or vehicle. The Anecortave Acetate 15 mg versus PDT Comparison Trial enrolled 530 patients to receive either anecortave acetate 15 mg every 6 months + sham PDT every 3 months or PDT with verteporfin every 3 months + sham PJD administration every 6 months. RESULTS: Anecortave acetate 15 mg was statistically superior to vehicle in the monotherapy trial at both 12 and 24 months for maintenance of vision and inhibition of CNV lesion growth. In the combination trial, a trend favored adding either anecortave acetate 15 mg or 30 mg to PDT for these two measures of clinical efficacy, but this short-duration study did not achieve statistical significance. Anecortave acetate 15 mg is comparable to PDT for maintaining vision over the 24-month period in the comparison trial. CONCLUSIONS: Anecortave acetate is safe and effective treatment for exudative age-related macular degeneration.

Anecortave acetate as monotherapy for treatment of subfoveal neovascularization in age-related macular degeneration: twelve-month clinical outcomes.

PURPOSE: To evaluate safety and efficacy of the angiostatic agent anecortave acetate, compared with a placebo, for treatment of subfoveal choroidal neovascularization (CNV). DESIGN: Ongoing masked, randomized, placebo-controlled, parallel evaluation of anecortave acetate (30 mg, 15 mg, and 3 mg) versus a placebo. PARTICIPANTS: There were 128 eyes of 128 patients with subfoveal CNV secondary to age-related macular degeneration who were enrolled and treated, with 80% (102/128) of eyes presenting with predominantly classic lesions at baseline. METHODS: All eyes received a posterior juxtascleral depot application of masked study medication or a placebo, with retreatment at 6-month intervals if the masked investigator believed the patient could benefit. Patients received periodic detailed ophthalmic examinations with both fluorescein and indocyanine green angiography, general physical examinations with electrocardiograms, and hematology/serum chemistry/urinalysis. All ophthalmic and systemic safety data were periodically reviewed by the Independent Safety Committee overseeing the study. MAIN OUTCOME MEASURES: Best-corrected logarithm of the minimum angle of resolution (logMAR) vision and fluorescein angiographic lesion characteristics were compared over time and among treatment groups. RESULTS: At month 12, anecortave acetate (15 mg) administered at 6-month intervals was statistically superior to the placebo for 3 measures of clinical efficacy: mean change from baseline vision (P = 0.0131), stabilization of vision (<3 logMAR line change; P = 0.0323), and prevention of severe vision loss (decrease of > or = 6 logMAR lines from baseline; P = 0.0224). Subgroup analysis of predominantly classic lesions revealed that anecortave acetate (15 mg) was also superior to the placebo at 1 year for each of these 3 measures of visual outcome (Ps = 0.0022, 0.0100, and 0.0299, respectively). Anecortave acetate (15 mg) trended toward significance over the placebo at month 12 for inhibition of total lesion growth and for inhibition of both the total CNV component and the classic CNV component in both the overall and subgroup analyses. The Independent Safety Committee identified no clinically relevant treatment-related safety issues. CONCLUSIONS: Anecortave acetate (15 mg) is safe and clinically efficacious at 1 year for maintaining vision, preventing severe vision loss, and inhibiting subfoveal CNV lesion growth.

Anecortave acetate as monotherapy for the treatment of subfoveal lesions in patients with exudative age-related macular degeneration (AMD): interim (month 6) analysis of clinical safety and efficacy.

PURPOSE: To evaluate clinical safety and efficacy of the angiostatic agent anecortave acetate for treatment of subfoveal choroidal neovascularization secondary to AMD. METHODS: 128 patients were randomized to placebo treatment or one of three anecortave acetate doses. Study medication was administered as a posterior juxtascleral injection onto the posterior scleral surface. Best-corrected logMAR vision was obtained at baseline and follow-up visits. Fluorescein angiograms were evaluated for eligibility before enrollment and posttreatment. RESULTS: Six months after a single treatment, visual acuity (mean change from baseline logMAR values) was significantly better (P = 0.003) after anecortave acetate 15 mg than placebo. More patients treated with anecortave acetate 15 mg than placebo maintained vision (88% versus 70%, P = 0.080), especially those with predominantly classic lesions (92% versus 65%, P = 0.021). Anecortave acetate 15 mg inhibited lesion growth significantly better than placebo (P = 0.001). Trends favoring the other doses over placebo were observed for vision preservation and lesion inhibition, but statistical significance was not achieved. The Independent Safety Committee overseeing this study identified no clinically relevant treatment-related changes. CONCLUSION: Anecortave acetate 15 mg is safe and effective for preserving or improving vision and for inhibiting lesion growth in patients with subfoveal AMD.
