Use of Imaging Modalities in Real Life: Impact on Visual Acuity Outcomes of Ranibizumab Treatment for Neovascular Age-Related Macular Degeneration in Germany.

ABSTRACT: Background:To date, there are limited prospective real-world data on the impact of optical coherence tomography (OCT) diagnostics on treatment outcomes in neovascular age-related macular degeneration (nAMD). Therefore, the prospective, noninterventional OCEAN study (NCT02194803) evaluated the use of OCT imaging and its impact on functional outcomes in Germany. Methods:The use of OCT imaging for treatment decisions was documented in nAMD patients receiving intravitreal ranibizumab injections at 347 study centres. Best-corrected visual acuity (BCVA) testing and treatment were performed according to routine clinical practice and documented over 24 months. Results:The majority of the 3,631 nAMD patients (59.6%) received a combination of OCT and fluorescein angiography imaging within the first 6 months. Over the remaining study course, this combination was used infrequently (range: 7.6% to 13.4%) and continually decreased over time; most patients received only OCT examinations (range: 48.9% to 52.5%; median: 3 within 12 months and 4 within 24 months). Subgroups according to the number of OCT examinations (?4, rarely OCT examined; 5-8, moderately OCT examined; ?8, well monitored) were associated with different treatment frequencies and outcomes: Rarely OCT-examined patients had received a median of 4 injections (range: 1-19) at 24 months; well-monitored patients had received a median of 8 injections (range: 1-21) at 24 months. Rarely OCT-examined patients had a mean change of BCVA of -0.3 letters (±26.1) at 24 months (n?=?165); well-monitored patients showed a change of +2.0 letters (±20.8) at 24 months (n?=?249). Time-to-response was greater for rarely examined than well-monitored patients, while duration-of-response was similar. Conclusion:Low number of visits as well as high number of treatment decisions without the use of OCT may contribute to undertreatment and poorer functional outcomes in patients undergoing ranibizumab treatment for nAMD in Germany. One potential reason for this could be that OCT was not covered by insurance for all patients during the study.

Project description:BackgroundClinical trials have established the efficacy of ranibizumab for the treatment of neovascular age-related macular degeneration (AMD). In addition, bevacizumab is used off-label to treat AMD, despite the absence of similar supporting data.MethodsIn a multicenter, single-blind, noninferiority trial, we randomly assigned 1208 patients with neovascular AMD to receive intravitreal injections of ranibizumab or bevacizumab on either a monthly schedule or as needed with monthly evaluation. The primary outcome was the mean change in visual acuity at 1 year, with a noninferiority limit of 5 letters on the eye chart.ResultsBevacizumab administered monthly was equivalent to ranibizumab administered monthly, with 8.0 and 8.5 letters gained, respectively. Bevacizumab administered as needed was equivalent to ranibizumab as needed, with 5.9 and 6.8 letters gained, respectively. Ranibizumab as needed was equivalent to monthly ranibizumab, although the comparison between bevacizumab as needed and monthly bevacizumab was inconclusive. The mean decrease in central retinal thickness was greater in the ranibizumab-monthly group (196 μm) than in the other groups (152 to 168 μm, P=0.03 by analysis of variance). Rates of death, myocardial infarction, and stroke were similar for patients receiving either bevacizumab or ranibizumab (P>0.20). The proportion of patients with serious systemic adverse events (primarily hospitalizations) was higher with bevacizumab than with ranibizumab (24.1% vs. 19.0%; risk ratio, 1.29; 95% confidence interval, 1.01 to 1.66), with excess events broadly distributed in disease categories not identified in previous studies as areas of concern.ConclusionsAt 1 year, bevacizumab and ranibizumab had equivalent effects on visual acuity when administered according to the same schedule. Ranibizumab given as needed with monthly evaluation had effects on vision that were equivalent to those of ranibizumab administered monthly. Differences in rates of serious adverse events require further study. (Funded by the National Eye Institute; ClinicalTrials.gov number, NCT00593450.).

Project description:ImportanceTo our knowledge, this is the first randomized clinical trial to compare visual outcomes and injection loads between ranibizumab and aflibercept using an identical treat-and-extend (TE) regimen for neovascular age-related macular degeneration (nAMD).ObjectiveTo report the results of the preplanned 12-month interim analysis of 2 predefined secondary efficacy end points of a randomized clinical trial.Design, setting, and participantsThe Comparison of Ranibizumab and Aflibercept for the Development of Geographic Atrophy in (Wet) AMD Patients (RIVAL) trial was conducted in 24 sites in Australia and included 281 treatment-naive eyes from 281 participants with active choroidal neovascularization secondary to nAMD and a visual acuity letter score of 23 or greater who were recruited between April 11, 2014, and October 31, 2015. A preplanned interim analysis was performed at month 12. Best-corrected visual acuity (BCVA) assessors and the central reading center, which determined treatment intervals, were masked to treatment assignments.InterventionsParticipants were randomized (1:1) to receive intravitreal injections of 0.5 mg of ranibizumab or 2.0 mg of aflibercept. After receiving 3 initial monthly injections, participants entered the TE phase.Main outcomes and measuresMean change in BCVA and the number of injections from baseline to month 12.ResultsOf 281 participants, 148 (52.7%) were women and the mean (SD) age was 77.7 (8.1) years. The baseline mean BCVA letter score (approximate Snellen equivalent) was 65.3 (20/50) in the ranibizumab arm and 65.1 (20/50) in the aflibercept arm. One hundred twenty-seven ranibizumab participants (90.1%) and 121 aflibercept participants (88.3%) completed month 12 with a mean (SD [Snellen equivalent]) BCVA letter score of 72.9 (15.5 [20/32]) and 70.5 (14.6 [20/40]), respectively. The mean change in BCVA letter scores from baseline to month 12 was 7.2 (95% CI, 5.5-8.9) for ranibizumab and 4.9 (95% CI, 3.1-6.6) for aflibercept (letter score difference, 2.3; 95% CI, -0.1 to 4.7; P = .06). The mean number of injections from baseline to month 12 was 9.7 in both the ranibizumab (SD, 2.8) and aflibercept (SD, 2.6) arms with a rate ratio of 1.00 (95% CI, 1.0-1.1; P = .86).Conclusions and relevanceOur findings suggest that neither aflibercept nor ranibizumab for nAMD are superior to the other regarding the average visual acuity gains and number of injections during 1 year in a TE regimen. Further follow-up to 2 years may determine if advantages of one over the other can be identified.Trial registrationClinicaltrials.Gov identifier: NCT02130024.

Project description:PurposeTo evaluate the effectiveness, safety, and treatment patterns of ranibizumab 0.5 mg in prior ranibizumab-treated patients with neovascular age-related macular degeneration (nAMD) enrolled in the LUMINOUS™ study.Patients and methodsLUMINOUS, a 5-year, prospective, multicenter, observational study, recruited 30,138 adult patients (treatment-naïve or prior ranibizumab-treated or other ocular treatments) across all approved indications for ranibizumab. Patients were treated as per local ranibizumab label of participating countries. Here we report the mean change in visual acuity (VA) at Year 1, treatment exposure, overall incidence of ocular, non-ocular adverse events (AEs) and serious AEs (SAEs) in prior ranibizumab-treated nAMD patients (n = 16,167).ResultsAt baseline, the mean (standard deviation [SD]) age of patients was 78.4 (9.0) years, 59.0% were female, and 80.0% were Caucasian. At Year 1 (n = 10,168), the mean (SD) VA change was -1.6 (12.6) letters (baseline VA: 58.3 [19.0] letters) with a mean (SD) of 4.7 (3.1) ranibizumab injections. Stratified by duration of prior ranibizumab treatment of <1 (n = 4,112), 1 to <2 (n = 2,095), 2 to <3 (n = 1,506), 3 to <4 (n = 1,123), 4 to <5 (n = 689), and ≥5 (n = 256) years, the mean (SD) VA change at Year 1 were -1.2 (13.5), -2.0 (12.3), -2.0 (11.3), -1.9 (11.8), -2.5 (10.9), and 0.0 (11.2) letters, respectively. Mean (SD) VA change in patients who received ≤6 and >6 injections over 1 year was -1.8 (13.8) and +0.5 (12.5) letters, respectively. The rate of ocular/non-ocular AEs and SAEs across all prior ranibizumab-treated patients over 5 years were 13.29%/23.02% and 0.84%/13.66%, respectively.ConclusionsOverall, regardless of the prior ranibizumab-treatment duration, VA was maintained in these patients at Year 1, and those receiving ≥6 injections showed a trend towards gaining letters. There were no new safety signals. These results may help inform routine clinical practice to appropriately treat nAMD patients with ranibizumab to achieve optimal visual outcomes.

Project description:ObjectiveTo determine the baseline predictors of visual acuity (VA) outcomes 1 year after treatment with ranibizumab or bevacizumab for neovascular age-related macular degeneration (AMD).DesignCohort study within the Comparison of Age-related Macular Degeneration Treatments Trials (CATT).ParticipantsA total of 1105 participants with neovascular AMD, baseline VA 20/25 to 20/320, and VA measured at 1 year.MethodsParticipants were randomly assigned to ranibizumab or bevacizumab on a monthly or as-needed schedule. Masked readers evaluated fundus morphology and features on optical coherence tomography (OCT). Visual acuity was measured using electronic VA testing. Independent predictors were identified using regression techniques.Main outcome measuresThe VA score, VA score change from baseline, and ?3-line gain at 1 year.ResultsAt 1 year, the mean VA score was 68 letters, mean improvement from baseline was 7 letters, and 28% of participants gained ?3 lines. Older age, larger area of choroidal neovascularization (CNV), and elevation of retinal pigment epithelium (RPE) were associated with worse VA (all P<0.005), less gain in VA (all P<0.02), and a lower proportion gaining ?3 lines (all P<0.04). Better baseline VA was associated with better VA at 1 year, less gain in VA, and a lower proportion gaining ?3 lines (all P<0.0001). Predominantly or minimally classic lesions were associated with worse VA than occult lesions (66 vs. 69 letters; P=0.0003). Retinal angiomatous proliferans (RAP) lesions were associated with more gain in VA (10 vs. 7 letters; P=0.03) and a higher proportion gaining ?3 lines (odds ratio, 1.9; 95% confidence interval, 1.2-3.1). Geographic atrophy (GA) was associated with worse VA (64 vs. 68 letters; P=0.02). Eyes with total foveal thickness in the second quartile (325-425 ?m) had the best VA (P=0.01) and were most likely to gain ?3 lines (P=0.004). Predictors did not vary by treatment group.ConclusionsFor all treatment groups, older age, better baseline VA, larger CNV area, predominantly or minimally classic lesion, absence of RAP lesion, presence of GA, greater total fovea thickness, and RPE elevation on optical coherence tomography were independently associated with less improvement in VA at 1 year.Financial disclosure(s)The author(s) have no proprietary or commercial interest in any materials discussed in this article.
