Ranibizumab in Diabetic Macular Oedema – A Benefit–risk Analysis of Ranibizumab 0.5 mg PRN Versus Laser Treatment
Introduction: The structured Benefit–risk Action Team (BRAT) approach aims to assist healthcare decision makers in treatment assessments. We applied BRAT to compare the benefit–risk profile of ranibizumab 0.5 mg versus laser photocoagulation for the treatment of diabetic macular oedema (DMO). Methods: One-year data for the ranibizumab 0.5 mg pro re nata (PRN) and laser arms of the phase III trials RESPOND (NCT01135914; n=220), RESTORE (NCT00687804; n=345), and REVEAL (NCT00989989; n=396) were included in the analysis. The benefit measures included ≥10 letters gain/avoidance of loss in best-corrected visual acuity (BCVA), achieving central retinal thickness (CRT) <275 μm, and 25-item Visual Function Questionnaire (VFQ-25) outcomes. The risks measures included endophthalmitis, intraocular pressure increase, hypertension, proteinuria, arterial/venous thromboembolic events and deaths. Results: Ranibizumab treatment provided significant benefits compared with laser for ≥10 letter BCVA gain at month 12 (387/1,000 versus 152/1,000 patients), CRT <275 μm at 12 months (474/1,000 versus 348/1,000 patients), and improvement of ≥6.06 on the VFQ-25 near activities subscale (325/1,000 versus 245/1,000 patients). Results for the risk measures were similar for both treatments. Conclusions: Superior clinically relevant outcomes were observed with ranibizumab 0.5 mg PRN compared with laser without compromising on safety. This analysis further supports the positive benefit–risk profile of ranibizumab 0.5 mg PRN.

The incidence of youth-onset type 2 diabetes (T2D) is increasing.1,2 Growing evidence has demonstrated that youth-onset T2D is rapidly progressive, with earlier onset of life-limiting complications compared with adult-onset T2D.3,4 Initiation of effective treatment that can restore beta cell function is critical. Until 2019, metformin and insulin were the only medications approved by the United States […]

Type 2 diabetes (T2DM) is a disease with a complex aetiopathogenesis that leads to a wide variety of metabolic disorders. This includes, by definition, high plasma glucose levels, but also elevated blood pressure, dyslipidaemia, cardiorenal complications and strokes. All of these disorders, beyond the progressive beta cell failure, derive from insulin resistance (IR).1 Among the many […]
