N2 - Purpose To evaluate the efficacy and safety of ranibizumab 0.5 mg treat-and-extend (T&E) versus monthly regimens in patients with neovascular age-related macular degeneration (nAMD) from the TReat and extEND (TREND) study. Design A 12-month phase 3b visual acuity (VA) assessor-masked, multicenter, randomized, interventional study. Participants Six hundred fifty patients. Methods Treatment-naïve nAMD patients (age, ≥50 years) were randomized 1:1 to receive either a ranibizumab 0.5 mg T&E (n = 323) or monthly (n = 327) regimen. Main Outcomes Measures The primary objective was to show noninferiority of ranibizumab 0.5 mg T&E versus monthly regimen, as assessed by the change in best-corrected VA (BCVA) from baseline to the end of the study. Secondary objectives included change in retinal central subfield thickness (CSFT) from baseline to the end of study, treatment exposure, and safety. Results Overall, 89.8% (T&E) and 90.2% (monthly) of patients completed the study. Patient demographic and baseline characteristics were well balanced between the 2 treatment groups. The T&E regimen was noninferior (P < 0.001) to the monthly regimen, with a least squares mean BCVA change from baseline of 6.2 versus 8.1 letters to the end of study, respectively. In both treatment groups, most BCVA improvements occurred during the first 6 months and were maintained until the end of the study. The mean change in CSFT from baseline to the end of study was −169.2 μm and −173.3 μm in the T&E and monthly groups, respectively. Fewer injections were required in patients receiving the T&E (8.7) versus monthly (11.1) regimen, with mean number of postbaseline visits of 8.9 and 11.2, respectively. Types and rates of adverse events were comparable between the treatment groups. Conclusions Ranibizumab 0.5 mg administered according to a T&E regimen was statistically noninferior and clinically comparable with a monthly regimen in improving VA from baseline to the end of study. No new safety signals for ranibizumab were identified.
