A 12-month, prospective, observational study of ranibizumab in treatment-naive Taiwanese patients with neovascular age-related macular degeneration: the RACER study.

ABSTRACT:

Background

The current National Health Insurance scheme in Taiwan reimburses 3 initial plus 4 additional injections of ranibizumab 0.5 mg for eligible patients with neovascular age-related macular degeneration (nAMD). The Ranibizumab AMD Clinical Efficacy in Real-world practice (RACER) study aimed to observe the effectiveness of ranibizumab injections under this reimbursement system.

Methods

RACER was a 12-month, prospective, observational study conducted in treatment-naïve, adult Taiwanese patients with nAMD. Patients received intravitreal ranibizumab 0.5 mg injections in adherence with local prescribing information.

Results

Of 161 patients enrolled, 114 (70.8%) completed the 12-month study. Overall, patients received a mean (standard deviation [SD]) of 4.3 (1.7) ranibizumab injections. The mean (SD, [95% confidence interval], P value) gain in best-corrected visual acuity (BCVA) from baseline at Month 3 was 5.2 (12.2, [3.1, 7.3] letters, P < 0.0001) and at Month 12 was 3.4 (15.4, [0.2-6.6] letters, P = 0.0352). Mean central retinal thickness also decreased from baseline at Months 3 and 12 (both P < 0.001). In subgroup analyses, better treatment outcomes at Months 3 and 12 were observed among patients who received a loading dose and those who had a shorter duration of nAMD at baseline. Adverse events were reported in 58.4% of patients; most (94.4%) were mild-to-moderate in severity and 98.8% were deemed unrelated to study treatment.

Conclusions

Treatment with ranibizumab 0.5 mg resulted in significant improvements in visual outcomes among treatment-naïve Taiwanese patients with nAMD. Early treatment and frequent dosing in the real-world setting may be the key to achieving better outcomes.

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:PurposeWe sought to determine the most cost-effective treatment for patients with newly diagnosed neovascular macular degeneration: monthly or as-needed bevacizumab injections, or monthly or as-needed ranibizumab injections.DesignCost-effectiveness analysis.ParticipantsHypothetical cohort of 80-year-old patients with newly diagnosed neovascular macular degeneration.MethodsUsing a mathematical model with a 20-year time horizon, we compared the incremental cost-effectiveness of treating a hypothetical cohort of 80-year-old patients with newly diagnosed neovascular macular degeneration using monthly bevacizumab, as-needed bevacizumab, monthly ranibizumab, or as-needed ranibizumab. Data came from the Comparison of Age-related macular degeneration Treatment Trial (CATT), the Medicare Fee Schedule, and the medical literature.Main outcome measuresCosts, quality-adjusted life-years (QALYs), and incremental costs per QALY gained.ResultsCompared with as-needed bevacizumab, the incremental cost-effectiveness ratio of monthly bevacizumab is $24,2 357/QALY. Monthly ranibizumab gains an additional 0.02 QALYs versus monthly bevacizumab at an incremental cost-effectiveness ratio of >$10 million/QALY. As-needed ranibizumab was dominated by monthly bevacizumab, meaning it was more costly and less effective. In sensitivity analyses assuming a willingness to pay of $100,000/QALY, the annual risk of serious vascular events would have to be ≥2.5 times higher with bevacizumab than that observed in the CATT trial for as-needed ranibizumab to have an incremental cost-effectiveness ratio of <$100,000/QALY. In another sensitivity analysis, even if every patient receiving bevacizumab experienced declining vision by 1 category (e.g., from 20/25-20/40 to 20/50-20/80) after 2 years but every patient receiving ranibizumab retained their vision level, as-needed ranibizumab would have an incremental cost-effectiveness ratio of $97,340/QALY.ConclusionsEven after considering the potential for differences in risks of serious adverse events and therapeutic effectiveness, bevacizumab confers considerably greater value than ranibizumab for the treatment of neovascular macular degeneration.

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:PurposeNeovascular age-related macular degeneration (nAMD) shows variable treatment response to intravitreal anti-VEGF. This analysis compared the potential of different artificial intelligence (AI)-based machine learning models using OCT and clinical variables to accurately predict at baseline the best-corrected visual acuity (BCVA) at 9 months in response to ranibizumab in patients with nAMD.DesignRetrospective analysis.ParticipantsBaseline and imaging data from patients with subfoveal choroidal neovascularization secondary to age-related macular dengeration.MethodsBaseline data from 502 study eyes from the HARBOR (NCT00891735) prospective clinical trial (monthly ranibizumab 0.5 and 2.0 mg arms) were pooled; 432 baseline OCT volume scans were included in the analysis. Seven models, based on baseline quantitative OCT features (Least absolute shrinkage and selection operator [Lasso] OCT minimum [min], Lasso OCT 1 standard error [SE]); on quantitative OCT features and clinical variables at baseline (Lasso min, Lasso 1SE, CatBoost, RF [random forest]); or on baseline OCT images only (deep learning [DL] model), were systematically compared with a benchmark linear model of baseline age and BCVA. Quantitative OCT features were derived by a DL segmentation model on the volume images, including retinal layer volumes and thicknesses, and retinal fluid biomarkers, including statistics on fluid volume and distribution.Main outcome measuresPrognostic ability of the models was evaluated using coefficient of determination (R2) and median absolute error (MAE; letters).ResultsIn the first cross-validation split, mean R2 (MAE) of the Lasso min, Lasso 1SE, CatBoost, and RF models was 0.46 (7.87), 0.42 (8.43), 0.45 (7.75), and 0.43 (7.60), respectively. These models ranked higher than or similar to the benchmark model (mean R2, 0.41; mean MAE, 8.20 letters) and better than OCT-only models (mean R2: Lasso OCT min, 0.20; Lasso OCT 1SE, 0.16; DL, 0.34). The Lasso min model was selected for detailed analysis; mean R2 (MAE) of the Lasso min and benchmark models for 1000 repeated cross-validation splits were 0.46 (7.7) and 0.42 (8.0), respectively.ConclusionsMachine learning models based on AI-segmented OCT features and clinical variables at baseline may predict future response to ranibizumab treatment in patients with nAMD. However, further developments will be needed to realize the clinical utility of such AI-based tools.Financial disclosuresProprietary or commercial disclosure may be found after the references.
