Small Immunomodulatory Molecules as Potential Therapeutics in Experimental Murine Models of Acute Lung Injury (ALI)/Acute Respiratory Distress Syndrome (ARDS).

BACKGROUND: Acute lung injury (ALI) or its most advanced form, acute respiratory distress syndrome (ARDS) is a severe inflammatory pulmonary process triggered by a variety of insults including sepsis, viral or bacterial pneumonia, and mechanical ventilator-induced trauma. Currently, there are no effective therapies available for ARDS. We have recently reported that a novel small molecule AVR-25 derived from chitin molecule (a long-chain polymer of N-acetylglucosamine) showed anti-inflammatory effects in the lungs. The goal of this study was to determine the efficacy of two chitin-derived compounds, AVR-25 and AVR-48, in multiple mouse models of ALI/ARDS. We further determined the safety and pharmacokinetic (PK) profile of the lead compound AVR-48 in rats. METHODS: ALI in mice was induced by intratracheal instillation of a single dose of lipopolysaccharide (LPS; 100 µg) for 24 h or exposed to hyperoxia (100% oxygen) for 48 h or undergoing cecal ligation and puncture (CLP) procedure and observation for 10 days. RESULTS: Both chitin derivatives, AVR-25 and AVR-48, showed decreased neutrophil recruitment and reduced inflammation in the lungs of ALI mice. Further, AVR-25 and AVR-48 mediated diminished lung inflammation was associated with reduced expression of lung adhesion molecules with improvement in pulmonary endothelial barrier function, pulmonary edema, and lung injury. Consistent with these results, CLP-induced sepsis mice treated with AVR-48 showed a significant increase in survival of the mice (80%) and improved lung histopathology in the treated CLP group. AVR-48, the lead chitin derivative compound, demonstrated a good safety profile. CONCLUSION: Both AVR-25 and AVR-48 demonstrate the potential to be developed as therapeutic agents to treat ALI/ARDS.

Topical lipoic acid choline ester eye drop for improvement of near visual acuity in subjects with presbyopia: a safety and preliminary efficacy trial.

OBJECTIVES: This study evaluated the safety of topical lipoic acid choline ester (UNR844, 1.5%) ophthalmic solution and its efficacy in improving distance-corrected near visual acuity (DCNVA) in subjects with presbyopia. SUBJECTS AND METHODS: This was a prospective, randomized, double-masked, and multicentre clinical trial. Subjects with a diagnosis of presbyopia (n = 75) were randomized 2:1 to UNR844 or placebo. On days 1-7, all subjects were dosed unilaterally (twice a day, b.i.d.) in their non-dominant eye to ensure safety and tolerability prior to days 8-91 when dosing was changed to bilateral (b.i.d.). Clinical assessments, including DCNVA and adverse events (AEs), were recorded at each study visit. Patients who completed the study were recruited into a non-interventional follow-up study that monitored them until 7 months after their final UNR844 exposure. The primary endpoints were safety and the mean change in DCNVA from baseline in the study eye. RESULTS: UNR844 administration (n = 50) produced no safety concerns and was well-tolerated, with no clinically-relevant changes in best-corrected distance visual acuity, pupil size, intraocular pressure, or discontinuations due to adverse events. DCNVA improved in the study eye in the UNR844 group compared to placebo during the 91 days of treatment [UNR844 vs. placebo, mean change in LogMAR (SD); -0.159 (0.120) vs. -0.079 (0.116)]. Bilateral DCNVA improved, with 53.1% UNR844 vs. 21.7% placebo subjects gaining ≥10 letters. Improvements in DCNVA were sustained at 5 and 7 months after UNR844 dosing ceased. CONCLUSIONS: These results support further development of UNR844 ophthalmic solution for the treatment of presbyopia.

Efficacy of olopatadine ophthalmic solution 0.2% in reducing signs and symptoms of allergic conjunctivitis.

Olopatadine hydrochloride ophthalmic solution 0.2% (Pataday, Alcon) is a new formulation of olopatadine hydrochloride ophthalmic solution, the first topical ocular antiallergic agent indicated for once-daily dosing. The aim of this study was to evaluate the safety, efficacy, onset, and duration of action of olopatadine 0.2% in the treatment of allergic conjunctivitis. Using the conjunctival allergen challenge, this double-masked, randomized by eye, parallel-group study included four visits over a 5-week period. Subjects were screened for eligibility (visit 1) and their ocular allergic responses were confirmed at visit 2. The efficacy of olopatadine in reducing the signs and symptoms of allergic conjunctivitis was evaluated at onset of action (visit 4) and 16 hours (visit 3) after masked medication instillation. The primary efficacy parameter was ocular itching. Safety parameters were also evaluated. Ninety subjects were evaluated. Olopatadine 0.2% was significantly (p < 0.001) more effective than placebo in the treatment of ocular itching at all time points at both the onset of action and the 16-hour allergen challenges. Olopatadine 0.2% was significantly (p < 0.03) more effective than placebo in the reduction of conjunctival redness, chemosis, and eyelid swelling at all time points (with the exception of conjunctival redness, which was significantly reduced at five of six time points). There were no serious adverse events and no treatment-related adverse events. Once-daily dosing with olopatadine 0.2% reduced the signs and symptoms of allergic conjunctivitis with a rapid and prolonged duration of action. Safety analyses indicated that olopatadine 0.2% was safe and well tolerated in subjects with a history of allergic conjunctivitis.

A novel in vivo rabbit model that mimics human dosing to determine the distribution of antibiotics in ocular tissues.

PURPOSE: The aim of this study was to establish a novel method to predict the human ocular penetration and distribution of topical antibiotics by using a controlled rabbit model that mimics the human eye with manual blinking and tear flow. METHODS: After anesthetizing the rabbits, a single dose of commercial antibiotic formulations was given with precision directly onto the cornea. This was followed by a 30-min controlled period applying manual blinking (4 blinks/min) and a supplementary tear flow (2 microL/min) that mimics the human eye. Tear samples were collected every 5 min and after euthanasia, conjunctival, aqueous humor, iris-ciliary body, and scleral samples were collected. The corneas were mounted in perfusion chambers to determine the level and continuing rate of release of the antibiotics, the levels of which were all determined using high-performance liquid chromatography analysis. RESULTS: U.S. formulations achieved conjunctival and corneal levels (µg/g) as follows: moxifloxacin, 6.6 +/- 0.3 and 50 +/- 5; tobramycin, 3.1 +/- 1.4 and 20 +/- 5; gentamicin, <2 and <2; levofloxacin, 1.5 +/- 0.3 and 19 +/- 2; gatifloxacin, 0.9 +/- 0.1 and 11 +/- 1; and trimethoprim, <0.1 and 2 +/- 1. Japan formulations achieved conjunctival and corneal levels as follows: levofloxacin 2.1 +/- 0.8 and 12 +/- 2; gatifloxacin, 2.2 +/- 0.9 and 7 +/- 1; ofloxacin, 1.6 +/- 0.5 and 7 +/- 1; and tosufloxacin, 0.7 +/- 0.1 and 1.5 +/- 0.3 (mean +/- standard error, n = 4). CONCLUSIONS: Moxifloxacin achieved the highest levels of antibiotic in ocular tissues. In the conjunctiva and cornea, the moxifloxacin level was 3-30 times the level of other fluoroquinolones, at least twice the level of the aminoglycosides, and 25 times the level of the antibacterial trimethoprim.

Safety and tolerability of olopatadine 0.2% in children and adolescents.

OBJECTIVE: The aim of this study was to evaluate the safety of olopatadine hydrochloride ophthalmic solution 0.2% in children and adolescents 3-17 years of age. METHODS: In this 6-week, randomized, double-masked safety evaluation, eligible subjects with asymptomatic eyes underwent in-office visits at weeks 1, 3, and 6 and were contacted by telephone at weeks 2, 4, and 5. Qualified subjects were assigned randomly in a 2:1 ratio of olopatadine 0.2% to vehicle (identical formation without the active ingredient) for dosing on a once-daily schedule. Safety parameters assessed included adverse events, visual acuity, ocular signs (slit-lamp assessments), dilated fundus examinations, intraocular pressure (IOP), pulse, and blood pressure. RESULTS AND DISCUSSION: An evaluation of 126 subjects (age range, 3-17) revealed no clinically relevant treatment-related changes in visual acuity, IOP, slit-lamp assessments, fundus examinations, or cardiovascular parameters. All adverse events reported were mild or moderate. CONCLUSIONS: Olopatadine 0.2% administered once-daily for 6 weeks is safe and well tolerated in children and adolescent patients.

Perception and quality of life associated with the use of olopatadine 0.2% (Pataday) in patients with active allergic conjunctivitis.

This 28-d, open-label, multicenter, single-arm clinical study was designed to evaluate perceptions of olopatadine 0.2% in patients with active ocular allergic signs and symptoms. The study enrolled 330 patients, 5 to 94 y of age, who had previously used olopatadine 0.1% for active allergic conjunctivitis. Most patients were white (n=230; 70.1%) and female (n=239; 72.9%). Of all enrolled patients, 328 were evaluable for analysis. Throughout the study, patients instilled 1 drop of olopatadine 0.2% into each eye once daily; adverse events were documented and ocular evaluations were conducted to ensure patient safety. Direct evaluations of efficacy were not performed. On days 1 and 7, patients completed the Rhinoconjunctivitis Quality of Life Questionnaire, recorded their perceptions of olopatadine 0.1% (day 1) or 0.2% (day 7), and had their ocular allergies assessed globally. On each of the first 6 d of treatment, patients also completed a telephone-based perception questionnaire. On day 28, patients returned to the study center, reported their treatment perceptions, had their ocular allergies assessed, and exited the trial. Overall, patients had a positive perception of olopatadine 0.2%. Patients were more satisfied with olopatadine 0.2% than they remembered being with olopatadine 0.1% (289 vs 257 patients; 87.6% vs 77.8%; P<.05). The majority of the 48 patients who wore contact lenses (n=42; 88%) believed that they could wear their contacts as desired. Significant improvement was noted in all categories of the Rhinoconjunctivitis Quality of Life Questionnaire (P<.0001). No unexpected safety findings were reported. Patients perceived olopatadine 0.2% to be effective and well tolerated.

Anecortave acetate (15 milligrams) versus photodynamic therapy for treatment of subfoveal neovascularization in age-related macular degeneration.

PURPOSE: To compare 1-year safety and efficacy of anecortave acetate 15 mg with photodynamic therapy (PDT) with verteporfin in patients eligible for initial PDT treatment. DESIGN: Prospective, masked, randomized, multicenter, parallel group, active control, noninferiority clinical trial. PARTICIPANTS: Five hundred thirty patients with predominantly classic subfoveal choroidal neovascularization secondary to age-related macular degeneration were randomized to treatment with either anecortave acetate 15 mg or PDT. METHODS: In the anecortave acetate group, the drug was administered under the Tenon's capsule as a periocular posterior juxtascleral depot (PJD) at the beginning of the study and at month 6. Before the first administration of anecortave acetate, patients in this treatment group received a sham PDT treatment, and sham PDT treatments were repeated every 3 months if there was evidence of leakage on fluorescein angiography (FA). Patients assigned to PDT received up to 4 PDT treatments at 3-month intervals, as needed based upon FA, and a sham PJD procedure at the beginning of the study and at month 6. Best-corrected visual acuity was determined at baseline and all follow-up visits. Safety data were regularly reviewed by an independent safety committee. MAIN OUTCOME MEASURE: Percent responders (patients losing <3 lines of vision) at month 12. RESULTS: Percent responders in the anecortave acetate and PDT groups were 45% and 49%, respectively (not statistically different, P = 0.43). The confidence interval (CI) for the difference ranged from -13.2% favoring PDT to +5.6% favoring anecortave acetate. The month 12 clinical outcome for anecortave acetate was improved in patients for whom reflux was controlled and who were treated within the 6-month treatment window (57% vs. 49%; 95% CI, -4.3% favoring PDT to +21.7% favoring anecortave acetate). No serious adverse events related to the study drug were reported in either treatment group. CONCLUSIONS: The safety and efficacy outcomes in this study demonstrate that the benefits of anecortave acetate for the treatment of choroidal neovascularization outweigh the risks associated with either the drug or the PJD administration procedure.

Ocular pharmacokinetics of moxifloxacin after topical treatment of animals and humans.

The ocular penetration and pharmacokinetics of moxifloxacin in comparison to other fluoroquinolones (ofloxacin, ciprofloxacin, gatifloxacin, norfloxacin, levofloxacin, and lomefloxacin) have been determined by in vitro and ex vivo techniques, as well as in animal and human studies. This article reviews the original pharmacokinetics work performed by Alcon and other studies reported in the ocular fluoroquinolone literature. The results consistently demonstrate higher maximum concentrations for moxifloxacin relative to the other fluoroquinolones in ocular tissues with levels well above its minimum inhibitory concentrations for relevant ocular pathogens. This superior performance is due to the unique structure of moxifloxacin that combines high lipophilicity for enhanced corneal penetration with high aqueous solubility at physiological pH. The latter property creates a high concentration gradient at the tear film/corneal epithelial interface providing a driving force for better ocular penetration for moxifloxacin. In addition, the higher concentration of moxifloxacin in VIGAMOX (i.e., 0.5% vs. 0.3%) allows more antibiotic to be available to ocular tissues. It is clear from the array of studies summarized in this report that moxifloxacin penetrates ocular tissues better (two- to three-fold) than gatifloxacin, ciprofloxacin, ofloxacin, or levofloxacin. This consistent, enhanced penetration of topical moxifloxacin offers powerful advantages for ophthalmic therapy.

Efficacy and safety of a fixed combination of travoprost 0.004%/timolol 0.5% ophthalmic solution once daily for open-angle glaucoma or ocular hypertension.

PURPOSE: To compare the efficacy of a fixed combination of travoprost 0.004%/timolol 0.5% every day in the morning with a concomitant regimen of timolol 0.5% every day in the morning, plus travoprost 0.004% every day in the evening; and timolol 0.5% twice daily on the intraocular pressure (IOP) of subjects with open-angle glaucoma or ocular hypertension over 3 months. DESIGN: Prospective, randomized, double-masked, parallel-group, active-controlled, multicenter trial. METHODS: Patients comprised adult subjects (n = 403) of either gender with open-angle glaucoma or ocular hypertension in at least one eye. To qualify, the IOP had to be between 22 to 36 mm Hg in the same eye at two consecutive eligibility visits. The primary outcome variable was IOP measured with a Goldmann applanation tonometer. RESULTS: Mean IOP ranged from 16.2 to 17.4 mm Hg with the combination travoprost/timolol compared with 15.4 to 16.8 mm Hg in the concomitant travoprost + timolol group, from baselines of 23.1 to 25.6 mm Hg and 22.9 to 25.0 mm Hg, respectively. The fixed combination of travoprost/timolol significantly lowered IOP by 7 to 9 mm, similar to the IOP reductions observed with concomitant therapy. The most frequent ocular adverse event was hyperemia that occurred in 14.3% and 23.4% of subjects treated with travoprost/timolol combination and concomitant travoprost + timolol, respectively. CONCLUSIONS: Travoprost/timolol combination produces greater IOP reductions than the positive control, timolol 0.5%, and reductions that were similar to concomitant travoprost + timolol. This study demonstrates that the fixed combination of travoprost/timolol produces significant and clinically relevant reductions of IOP in a once-daily dosing regimen.

Effects of a new formulation of olopatadine ophthalmic solution on nasal symptoms relative to placebo in two studies involving subjects with allergic conjunctivitis or rhinoconjunctivitis.

BACKGROUND: A new formulation of olopatadine hydrochloride ophthalmic solution (olopatadine 0.2%) was evaluated in two separate, randomized, placebo-controlled, double-masked, hybrid environmental studies intended to determine efficacy and safety in subjects with histories of seasonal allergic conjunctivitis or rhinoconjunctivitis. DESIGN AND METHODS: In these 10- and 12-week trials (conducted April-August 2003 and July-December 2001, respectively), subjects assessed their ocular signs and symptoms. Additionally, subjects in the 10-week trial evaluated the frequency of their nasal symptoms while subjects in the 12-week trial evaluated both the frequency and severity of their nasal symptoms. The two trials had a combined enrollment of 500 subjects (217 males, 283 females) including 44 children aged 10-17 years; the combined population was 81.4% Caucasian, 9.2% Black, 2% Hispanic, and 7.4% other. Daily throughout these studies, either ragweed (fall study) or grass (spring study) pollen counts were obtained from each investigative center. Slope analyses were conducted on the nasal symptom assessments by pollen count. RESULTS: The nasal results from the two clinical trials are presented herein. In the fall study, relative to placebo, olopatadine 0.2% significantly reduced the frequency of pollen effects on sneezing (p = 0.0355) and itchy nose (p = 0.0032), and reduced the severity of pollen effects on sneezing (p = 0.0451), itchy nose (p = 0.0178), and runny nose (p = 0.0327). In the spring study, olopatadine 0.2% significantly reduced the frequency of pollen effects on sneezing (p = 0.0017) and runny nose (p = 0.0031) relative to placebo. In the fall trial, 2 subjects discontinued due to treatment-related adverse events (tachycardia and dry eye), while in the spring study, no subject discontinued due to a treatment-related adverse event. No subject in either study suffered a treatment-related serious adverse event. CONCLUSIONS: For the subjects enrolled in these studies, olopatadine 0.2% appeared to be safe, well-tolerated, and effective in significantly reducing the frequency and/or severity of some effects of pollen on nasal symptoms.

Clinical efficacy of olopatadine hydrochloride ophthalmic solution 0.2% compared with placebo in patients with allergic conjunctivitis or rhinoconjunctivitis: a randomized, double-masked environmental study.

BACKGROUND: Previous studies have suggested that olopatadine hydrochloride ophthalmic solution 0.2% administered once daily is effective for up to 24 hours after instillation and is well tolerated in adults and children aged > or =3 years. OBJECTIVE: The goal of this study was to evaluate the efficacy and safety profile of olopatadine 0.2% compared with placebo in patients with seasonal allergic conjunctivitis or rhinoconjunctivitis. METHODS: This was a 10-week, randomized, placebo-controlled, double-masked environmental study conducted during the spring allergy season (April-August) of 2003. Patients assessed their ocular signs and symptoms in terms of frequency (whole-unit scale from 0 to 5) and severity (half-unit scale from 0 to 4), and grass pollen counts were obtained daily for each investigative site. Responder analyses were conducted by pollen level (frequency based) and pollen period (severity based) to evaluate the clinical significance of differences in ocular itching and redness between treatment groups. RESULTS: Two hundred sixty patients (137 females, 123 males) were enrolled in the study, including 28 children aged between 11 and 17 years; the overall population was 74% white, 11% black, 4% Hispanic, and 11% other. The frequency-based responder analyses of ocular itching and redness showed that when grass pollen counts were high (>20 gr/m(3) air), a respective 21% and 14% of patients in the olopatadine 0.2% group assessed the frequency of ocular itching and redness as >2, compared with 47% and 31% of patients in the placebo group (P < 0.001 for ocular itching; P < 0.003 for redness). The results of the severity-based responder analyses by peak pollen period were consistent with those of the frequency-based analyses. Compared with placebo, olopatadine 0.2% was associated with significant reductions in calculated mean scores for ocular itching and redness by pollen level and by pollen period. No patient was discontinued from the study because of a treatment-related adverse event, and no patient experienced a treatment-related serious adverse event. CONCLUSION: In the patients studied, olopatadine 0.2% appeared to be effective and well tolerated when administered once daily for the treatment of the ocular signs and symptoms of allergic conjunctivitis or rhinoconjunctivitis.

Preclinical and clinical antiallergic effect of olopatadine 0.2% solution 24 hours after topical ocular administration.

Pharmacologic studies examined the potential of a solution containing olopatadine to maintain and extend antiallergic efficacy after single topical ocular drop administration over 24 hours. Results of these preclinical experiments conducted in guinea pigs indicated that olopatadine 0.2% (wt/vol) solution was significantly effective 24 hours after dosing. This concentration of olopatadine provided significantly more efficacy than Patanol (olopatadine 0.1%) 24 hours after administration while being as effective as Patanol (olopatadine 0.1%) 5 minutes after administration. Results from a human conjunctival allergen challenge trial in sensitive subjects confirmed clinical efficacy of olopatadine 0.2% solution over 24 hours. When individuals were challenged with antigen at onset, 16 and 24 hours after drug administration onto the eye, significant reductions were observed in the scores for active drug as compared with placebo for pruritus (77, 77, and 61%), conjunctival redness (35, 28, and 20%), and chemosis (53, 41, and 31%), respectively. These data suggest that topically applied olopatadine 0.2% solution will be an effective once-a-day therapy for allergic conjunctivitis.

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.

Response to travoprost in black and nonblack patients with open-angle glaucoma or ocular hypertension.

Two prospective, controlled, multicenter, double-masked studies--one lasting 6 months (n=594) and the other, 12 months (n=787)--examined the intraocular pressure (IOP)-lowering efficacy of travoprost in 1381 black and nonblack patients with open-angle glaucoma or ocular hypertension. Investigated regimens were travoprost 0.004% once daily, latanoprost 0.005% once daily, and timolol 0:5% twice daily. In both studies, mean IOP was significantly lower in blacks treated with travoprost. The IOP reduction was also significantly greater in blacks after adjustments for age, sex, iris color, diagnosis, and corneal thickness. Timolol lowered mean IOP to a greater extent in nonblack patients. The significantly larger IOP reduction with travoprost compared with timolol in both racial groups was more pronounced in blacks. Travoprost also was superior to latanoprost in blacks. Mean changes from baseline generally were greater for black than for nonblack patients, although the differences did not achieve statistical significance. The response rate to travoprost was higher in blacks. The most common adverse effect was hyperemia.

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.
