RESUMEN

Importance: The port delivery system (PDS) with ranibizumab has demonstrated noninferior and equivalent efficacy compared with monthly intravitreal injections of ranibizumab, an anti-vascular endothelial growth factor (VEGF) agent, in patients with neovascular age-related macular degeneration (nAMD), but evaluating patient preference is important to help inform clinical decision-making. Objective: Evaluate treatment satisfaction for ranibizumab delivered via PDS vs intravitreal injections as well as patient preference among those assigned to PDS. Design, Setting, and Participants: Archway was a phase 3 randomized active-comparator open-label clinical trial conducted at 78 sites in the US. Patients 50 years and older with nAMD diagnosed within 9 months of screening with a documented response to anti-VEGF therapy were included. Of 619 patients screened, 418 were enrolled; 415 were included in the primary analysis and 234 were included in the secondary exploratory analysis. The Archway study ran from September 12, 2019, through primary readout on May 22, 2020. Interventions: Patients were randomized 3:2 to PDS with ranibizumab, 100 mg/mL, with fixed refill exchanges every 24 weeks or intravitreal ranibizumab injections, 0.5 mg, every 4 weeks. Main Outcomes and Measures: Treatment satisfaction was measured using the Macular Disease Treatment Satisfaction Questionnaire in the PDS and intravitreal injection arms at week 40. Patient preference was assessed using the content-validated PDS Patient Preference Questionnaire (PPPQ), which measured the proportion of patients in the PDS arm with monthly monitoring who preferred treatment with the PDS at week 40 over previous intravitreal injections or concurrent fellow-eye injections. Both outcomes were exploratory end points. Results: The mean (SD) age of participants at baseline was 75.0 (7.9) years; 234 participants (59%) were women and 162 (41%) were men. At week 40, differences in overall treatment satisfaction scores were minimal for the PDS and intravitreal injection arms (mean, 68.0; 95% CI, 67.4-68.6; n = 237 and mean, 66.1; 95% CI, 64.9-67.3; n = 159, respectively; difference, 1.9; 95% CI, 0.7-3.1). A total of 234 of 248 patients (94.4%) in the PDS arm were included in the PPPQ analysis. At week 40, almost all patients in the PDS arm preferred treatment via PDS (218 of 234 [93.2%]) vs previous intravitreal injections (3 of 234 [1.3%]), including 172 of 234 (73.5%) with a very strong preference for the PDS. In patients who received concurrent fellow-eye injections (n = 78), 72 (92.3%) preferred the PDS. Conclusions and Relevance: Although PDS treatment was preferred by almost all patients assigned to PDS over previous intravitreal injections, both delivery methods have high treatment satisfaction. These findings provide further evidence for the PDS as a meaningful alternative treatment option for patients with nAMD. Trial Registration: ClinicalTrials.gov Identifier: NCT03677934.

RESUMEN

PURPOSE: To evaluate the safety and efficacy of the Port Delivery System with ranibizumab (PDS) for the treatment of neovascular age-related macular degeneration (nAMD). DESIGN: Phase 3, open-label, randomized, visual acuity assessor-masked noninferiority and equivalence trial. PARTICIPANTS: Patients with nAMD diagnosed within 9 months of screening previously treated with and responsive to anti-vascular endothelial growth factor therapy. METHODS: Patients were randomized 3:2 to treatment with the PDS with ranibizumab 100 mg/ml with fixed 24-week (Q24W) refill-exchanges (PDS Q24W) or intravitreal ranibizumab 0.5-mg injections every 4 weeks (monthly ranibizumab). MAIN OUTCOME MEASURES: Primary end point was change in best-corrected visual acuity (BCVA) Early Treatment Diabetic Retinopathy Study letter (letters) score from baseline averaged over weeks 36 and 40 (noninferiority margin,-4.5 letters; equivalence margin, ±4.5 letters). RESULTS: Archway enrolled 418 patients; 251 were randomized to and 248 received treatment with the PDS Q24W, and 167 were randomized to and received treatment with monthly ranibizumab. Baseline BCVA was 74.4 letters (PDS Q24W arm) and 75.5 letters (monthly ranibizumab arm; Snellen equivalent, 20/32). Adjusted mean change in BCVA score from baseline averaged over weeks 36 and 40 was +0.2 letters (standard error [SE], 0.5 letters) in the PDS Q24W arm and +0.5 letters (SE, 0.6 letters) in the monthly ranibizumab arm (difference, -0.3 letters; 95% confidence interval, -1.7 to 1.1 letters). PDS Q24W was both noninferior and equivalent to monthly ranibizumab. Of 246 PDS-treated patients assessed for supplemental ranibizumab treatment, 242 (98.4%) did not receive supplemental ranibizumab treatment before the first refill-exchange procedure, including 4 patients who discontinued treatment before the first refill-exchange procedure. Prespecified ocular adverse events of special interest were reported in 47 patients (19.0%) in the PDS Q24W arm and 10 patients (6.0%) in the monthly ranibizumab arm, which included, in the former arm, 4 (1.6%) endophthalmitis cases, 2 (0.8%) retinal detachments, 13 (5.2%) vitreous hemorrhages, 6 (2.4%) conjunctival erosions, and 5 (2.0%) conjunctival retractions. Most ocular adverse events in the PDS Q24W arm occurred within 1 month of implantation. CONCLUSIONS: Archway met its primary objective and PDS Q24W demonstrated noninferior and equivalent efficacy to monthly ranibizumab, with 98.4% of PDS-treated patients not receiving supplemental treatment in the first 24-week interval.

RESUMEN

PURPOSE: To report the end-of-study results from the Ladder clinical trial of the Port Delivery System with ranibizumab (PDS) for the treatment of neovascular age-related macular degeneration (nAMD). DESIGN: Multicenter, randomized, active treatment-controlled phase 2 clinical trial. PARTICIPANTS: Patients diagnosed with nAMD with a documented response to anti-vascular endothelial growth factor treatment who received study treatment (N = 220). METHODS: Patients were randomized 3:3:3:2 to treatment with the PDS filled with ranibizumab 10-mg/ml, 40-mg/ml, and 100-mg/ml formulations or monthly intravitreal ranibizumab 0.5-mg injections. MAIN OUTCOME MEASURES: End-of-study results for the time to first meeting refill criteria (first refill), mean change from baseline for best-corrected visual acuity (BCVA) and central foveal thickness (CFT), and safety. RESULTS: At study end, the mean time on study was 22.1 months (range, 10.8-37.6 months) for all PDS patients. Median time to first refill was 8.7 months, 13.0 months, and 15.8 months, and 28.9%, 56.0%, and 59.4% of patients went 12 months or longer without meeting refill criteria in the PDS 10-mg/ml, 40-mg/ml, and 100-mg/ml treatment arms, respectively. At month 22, the observed mean BCVA change from baseline was ‒4.6 Early Treatment Diabetic Retinopathy Study (ETDRS) letters, ‒2.3 ETDRS letters, +2.9 ETDRS letters, and +2.7 ETDRS letters in the PDS 10-mg/ml, 40-mg/ml, 100-mg/ml, and monthly intravitreal ranibizumab 0.5-mg treatment arms, respectively. At month 22, the observed mean CFT change from baseline was similar in the PDS 100-mg/ml and monthly intravitreal ranibizumab 0.5-mg treatment arms. No new safety signals were detected during the additional follow-up. CONCLUSIONS: Over a mean of 22 months on study, vision and anatomic outcomes were comparable between the PDS 100-mg/ml and monthly intravitreal ranibizumab 0.5-mg arms, with a lower total number of ranibizumab treatments with the PDS. The Ladder end-of-study findings were consistent with the primary analysis, and the PDS generally was well tolerated throughout the entire study period. The PDS has the potential to reduce treatment burden in patients with nAMD while maintaining vision.
