Comparing the effectiveness of bevacizumab to ranibizumab in patients with exudative age-related macular degeneration. The BRAMD study

Purpose: To compare the effectiveness of bevacizumab and ranibizumab in the treatment of exudative age-related macular degeneration (AMD). Design: Multicentre, randomized, controlled, double-masked clinical trial in 327 patients. The noninferiority margin was 4 letters. Patients: Patients ≥ 60 years of age with primary or recurrent sub- or juxtafoveal choroidal neovascularization (CNV) secondary to AMD with a total area of CNV < 12 disc areas and a best corrected visual acuity (BCVA) score between 20 and 78 letters on an EDTRS like chart in the study eye. Methods: Monthly intravitreal injections with 1.25 mg bevacizumab or 0.5 mg ranibizumab were given during one year. Intention to treat with last observation carried forward analysis was performed. Main Outcome Measures: Primary outcome was the change in BCVA in the study eye from baseline to 12 months. Results: The mean gain in BCVA was 5.1 (±14.1) letters in the bevacizumab group (n = 161) and 6.4 (±12.2) letters in the ranibizumab group (n = 166) (p = 0.37). The lower limit of the 95% confidence interval of the difference in BCVA gain was 3.72. The response to bevacizumab was more varied; 24% of patients showed a gain of ≥15 letters, 11% a loss of ≥15 letters and 65% a gain or loss < 15 letters compared to 19%, 5% and 76% respectively for ranibizumab (p = 0.038). No significant differences in absolute CRT and CRT change (p = 0.13) or in the presence of subretinal or intraretinal fluid (p = 0.14 and 0.10, respectively) were observed. However, the presence of any fluid on SD-OCT (subretinal and/or intraretinal) differed significantly (p = 0.020), with definite fluid on SD-OCT in 45% of the patients for bevacizumab versus 31% for ranibizumab. The occurrence of serious adverse events and adverse events was similar, with 34 SAEs and 256 AEs in the bevacizumab group and 37 SAEs and 299 AEs in the ranibizumab group (p = 0.87 and p = 0.48, respectively). Conclusions: Bevacizumab was not inferior to ranibizumab. The response to bevacizumab was more varied with higher percentages of both gainers and losers and more frequently observed retinal fluid on SD-OCT at 12 months when compared to the ranibizumab group.

Comparing the effectiveness and costs of Bevacizumab to Ranibizumab in patients with Diabetic Macular Edema: A randomized clinical trial (the BRDME study)

Background: The effectiveness of ranibizumab in the treatment of diabetic macular edema has been proven with large clinical trials. For bevacizumab only two clinical trials have been published and a head-to-head comparison is lacking to date. However, if proved non-inferior to ranibizumab, use of the off-label bevacizumab could reduce costs enormously without a loss in visual acuity. A cost-effectiveness study has been designed to substantiate this hypothesis. Aim: To compare the effectiveness and costs of 1.25 mg of bevacizumab to 0.5 mg ranibizumab given as monthly intravitreal injections during 6 months in patients with diabetic macular edema. It is hypothesized that bevacizumab is non-inferior to ranibizumab regarding its effectiveness. Design: This is a randomized, controlled, double masked, clinical trial in 246 patients in seven academic trial centres in The Netherlands. Outcomes: The primary outcome measure is the change in best-corrected visual acuity (BCVA) in the study eye from baseline to month 6. Secondary outcomes are the proportions of patients with a gain or loss of 15 letters or more or a BCVA of 20/40 or more at 6 months, the change in leakage on fluorescein angiography and the change in foveal thickness by optical coherence tomography at 6 months, the number of adverse events in 6 months, and the costs per quality adjusted life-year of the two treatments

Real-world treatment outcomes of neovascular Age-related Macular Degeneration in the Netherlands

Purpose: To compare treatment outcomes of treatment-naïve eyes with neovascular age-related macular degeneration (nAMD) with bevacizumab as the first-line treatment, according to the guidelines of the Dutch Ophthalmological Society, with those treated first with either ranibizumab or aflibercept, as used in many other countries, all treated using a treat-and-extend strategy. Methods: Data were obtained from the prospectively designed Fight Re

INTRODUCTION: Because of the great potential of vascular endothelial growth factor inhibitors (anti-VEGF) for retinal exudative diseases, an increased number of patients receives this treatment. However, during this treatment, patients are subjected to frequent invasive intravitreal injections, and the effects on reversing the process of vision loss are uncertain, which may have negative consequences for patients' mental health. One in three patients experience at least mild symptoms of depression/anxiety. To support patients in dealing with these symptoms, an e-mental health intervention (called E-PsEYE) has been developed. E-PsEYE is based on cognitive-behavioural therapy (CBT) and contains nine modules. A stepped-care model with three steps will be used to deliver the intervention: (1) providing information and psychoeducation, (2) when symptoms of depression/anxiety persist, guided CBT is offered and supported by social workers from low vision rehabilitation services and (3) when symptoms still persist, patients are referred to their general practitioner.METHODS AND ANALYSIS: An economic evaluation from a healthcare and societal perspective will be conducted alongside a multicentre randomised controlled trial in two parallel groups to evaluate whether E-PsEYE is cost-effective in comparison with usual care. Participants (n=174) will be 50 years or older, have retinal exudative diseases, receive anti-VEGF treatment and have mild symptoms of depression/anxiety (assessed prior to randomisation). Main outcome measures are: depression (Patient Health Questionnaire-9), anxiety (Hospital Anxiety and Depression Scale-Anxiety) and quality-adjusted life-years (determined with the Health Utility Index-3 and the EuroQol-5 dimensions). Five measurements take place: at baseline and after 3, 6, 9 and 12 months.ETHICS AND DISSEMINATION: The study has been approved by the Medical Ethics Committee of the VU University Medical Centre Amsterdam. It will provide new and essential information on the cost-effectiveness of an innovative intervention for a vulnerable population. Outcomes will be disseminated through peer-reviewed publications and conference presentations.TRIAL REGISTRATION: http://www.trialregister.nl, identifier: NTR6337
