PURPOSE:To report the efficacy, durability, and safety of intravitreal aflibercept 8 mg versus intravitreal aflibercept 2 mg every 8 weeks (2q8) in patients with neovascular age-related macular degeneration (nAMD) through 96 weeks, PULSAR (ClinicalTrials.gov identifier, NCT04423718). DESIGN:Phase 3, randomized, noninferiority, 96-week trial. PARTICIPANTS:Treatment-naive adults ≥ 50 years with nAMD. METHODS:Patients were randomized 1:1:1 to intravitreal aflibercept 8 mg every 12 or 16 weeks (8q12 or 8q16), or 2q8, after 3 initial monthly doses; dosing intervals in 8-mg groups were modified based on prespecified criteria. MAIN OUTCOME MEASURES:Change from baseline in best-corrected visual acuity (BCVA) and central retinal thickness (CRT), proportion of patients maintaining or extending the randomized dosing intervals, and safety outcomes. RESULTS:Of 1009 patients treated, 869 patients (8q12, n = 291; 8q16, n = 292; 2q8, n = 286) completed treatment through week 96. Least squares (LS) mean change from baseline in BCVA at week 96 was +5.6 (95% confidence interval [Cl], 4.1-7.1), +5.5 (95% Cl, 4.0-7.0), and +6.6 (95% Cl, 5.2-8.0) letters in the 8q12, 8q16, and 2q8 groups, respectively; 8q12 and 8q16 differences versus 2q8 in LS mean BCVA changes at week 96 met the noninferiority criteria specified for the primary end point at week 48. Mean (standard deviation) change in CRT from baseline was -143.9 (123.6) μm, -153.4 (140.8) μm, and -135.8 (133.1) μm in the 8q12, 8q16, and 2q8 groups, respectively. Patients completing 96 weeks of treatment in the 8q12, 8q16, and 2q8 groups received a mean of 9.7, 8.2, and 12.8 active injections, respectively. Of these, 87% of patients in the 8q12 group had last assigned dosing intervals of 12 weeks or more, whereas 78%, 53%, and 31% of patients in the 8q16 group qualified for last assigned dosing intervals of ≥ 16 weeks, ≥ 20 weeks, and 24 weeks, respectively. Incidence of ocular treatment-emergent adverse events was similar across groups. CONCLUSIONS:Aflibercept 8 mg delivered sustained disease control in patients with nAMD, maintaining improvements in visual and anatomic outcomes through week 96 with extended dosing intervals and similar safety profile to aflibercept 2 mg.

BackgroundIntravitreal aflibercept 8 mg could improve treatment outcomes and provide sustained disease control in patients with neovascular age-related macular degeneration (nAMD), with extended dosing compared with aflibercept 2 mg.MethodsPULSAR is a phase 3, randomised, three-group, double-masked, non-inferiority, 96-week trial conducted across 223 sites worldwide. Adults with nAMD were randomised 1:1:1 to aflibercept 8 mg every 12 weeks (8q12), aflibercept 8 mg every 16 weeks (8q16), or aflibercept 2 mg every 8 weeks (2q8), following three initial monthly doses in all groups. From week 16, patients in the aflibercept 8 mg groups had their dosing interval shortened if pre-specified dose regimen modification criteria denoting disease activity were met. The primary endpoint was change from baseline in best-corrected visual acuity (BCVA) at week 48. All patients with at least one dose of study treatment were included in the efficacy and safety analyses. This trial is registered with ClinicalTrials.gov (NCT04423718) and is ongoing.FindingsOf 1011 patients randomised to aflibercept 8q12 (n=336), 8q16 (n=338), or 2q8 (n=337) between Aug 11, 2020, and July 30, 2021, 1009 patients received study treatment (aflibercept 8q12 n=335; aflibercept 8q16 n=338; and aflibercept 2q8 n=336). Aflibercept 8q12 and 8q16 showed non-inferior BCVA gains versus aflibercept 2q8 (mean BCVA change from baseline +6·7 [SD 12·6] and +6·2 [11·7] vs +7·6 [12·2] letters). The least squares mean differences between aflibercept 8q12 versus 2q8 and 8q16 versus 2q8, respectively, were −0·97 (95% CI −2·87 to 0·92) and −1·14 (−2·97 to 0·69) letters (non-inferiority margin at 4 letters). The incidence of ocular adverse events in the study eye was similar across groups (aflibercept 8q12 n=129 [39%]; aflibercept 8q16 n=127 [38%]; and aflibercept 2q8 n=130 [39%]).InterpretationAflibercept 8 mg showed efficacy and safety with extended dosing intervals, which has the potential to improve the management of patients with nAMD.FundingBayer AG and Regeneron Pharmaceuticals.
OBJECTIVE:The Port Delivery System with ranibizumab (PDS) is approved in the United States for neovascular age-related macular degeneration (nAMD). Portal (NCT03683251) is evaluating long-term safety and tolerability of the PDS in patients with nAMD who completed the phase II Ladder (NCT02510794) or phase III Archway (NCT03677934) trials. DESIGN:Multicenter, nonrandomized, open-label, extension clinical trial. PARTICIPANTS:All-PDS safety population (N = 555) comprises patients enrolled in Portal who completed Ladder or Archway. Because of data availability, efficacy population comprises Ladder-to-Portal patients only: patients who previously received PDS 10, 40, or 100 mg/mL pro re nata (as-needed [PRN]; n = 58, 62, and 59, respectively) or monthly intravitreal ranibizumab 0.5-mg injections (monthly ranibizumab; n = 41) in Ladder and subsequently enrolled in Portal. METHODS:Ladder patients received PDS refill-exchanges PRN or monthly ranibizumab. Archway patients received PDS 100 mg/mL with fixed refill-exchanges every 24 weeks (Q24W) or monthly ranibizumab. Once enrolled in Portal, all patients receive PDS Q24W from day 1. MAIN OUTCOME MEASURES:Ocular adverse events of special interest (AESIs); changes from baseline in best-corrected visual acuity (BCVA) and center point thickness (CPT); supplemental ranibizumab treatment between refill-exchange procedures; and PDS Patient Preference Questionnaire results. RESULTS:In the All-PDS safety population (mean follow-up, 111 weeks), 137 (24.7%) patients had ≥1 ocular AESI; most common were cataract (11.4%), vitreous hemorrhage (6.1%), and conjunctival thickening (bleb)/filtering bleb leak (6.3%). Endophthalmitis occurred in 11 of 555 (2.0%) patients. For Ladder-to-Portal patients previously treated with PDS 100 mg/mL or monthly ranibizumab, BCVA remained stable from baseline to month 48; mean (95% confidence interval) changes from baseline were 0.1 (-6.6 to 6.8; n = 31) and 2.3 (-9.4 to 14.1; n = 15) letters, respectively; CPT remained stable through month 48. Approximately 95% of patients did not need supplemental treatment before each refill-exchange for >2 years since Portal enrollment. Of Ladder-to-Portal previous monthly ranibizumab patients, 92% preferred the PDS over injections. CONCLUSIONS:Interim results from Portal suggest 4-year maintenance of visual/anatomic outcomes with PDS 100 mg/mL, with the PDS preferred to monthly injections. Long-term safety profile of the PDS is well characterized. FINANCIAL DISCLOSURE(S):Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.
All previous home optical coherence tomography studies were observational only, and no patient care activity was undertaken based on remote images. This is the first time that home optical coherence tomography data drove patient management decisions. The results substantiate the expectation that the home optical coherence tomography will personalize neovascular age-related macular degeneration care and reduce the treatment burden. Purpose:To evaluate the impact of home optical coherence tomography (OCT)-guided patient management on treatment burden and visual outcomes.Methods:An interventional trial was conducted to compare frequency of treatment and visual acuity for the neovascular age-related macular degeneration patients before and during use of home optical coherence tomography over a period of 6 months. Patient adherence to regular scanning was measured by the number of scans performed per week. The characteristics of episodes of fluid recurrence and classification of typical fluid volume trajectories were performed.Results:Twenty-seven eyes (21 with diagnosis of neovascular age-related macular degeneration and one converted during the study), of 15 patients were monitored for 6 months, scanning at 6.2 times/week per eye and yielding 4,435 scans of which 91.2% were eligible for artificial intelligence-based fluid volume quantification. Total number of monitoring weeks before and during the study were 1,555 and 509. The mean (SD) number of weeks per injection before and during home OCT management were 8.0 (4.7) and 15.3 (8.5) (P = 0.004), respectively. The mean (SD) visual acuity change before and during home OCT-based management was 3.5 (12.0) letters and 0.0 (9.5) letters (P = 0.45), respectively, showing no significant impact on visual acuity.Conclusion:For the first time, remote patient monitoring with a home OCT allowed personalized management of neovascular age-related macular degeneration. This study showed significant reduction in treatment burden while maintaining stable visual acuity.
We report changes in DR severity over time from the PANORAMA study of aflibercept versus sham in patients with moderately severe/severe NPDR that can help physicians and patients make informed management decisions for optimal outcomes.
