Real world evidence of retinal vein occlusion (RVO) patient treatment with ranibizumab in Germany based on the 24 months interim results of the non-interventional, observational PACIFIC study

Abstract

Purpose : The PACIFIC study aims to describe the current state of ranibizumab patient care across several indications including neovascular AMD, diabetic macula edema, branch retinal vein occlusion (BRVO), central retinal vein occlusion (CRVO) and other choroidal neovascularization in Germany, the Netherlands and Switzerland. Here, we will focus on the RVO subgroup within the German cohort.

Methods : The PACIFIC study is a non-interventional, open label, multi-centric study aiming to collect real world evidence regarding the use of ranibizumab. 4,553 patients were recruited in Germany across 169 centers and followed for up to 24 months. We present data of 24 months RVO treatment with ranibizumab (362 BRVO and 259 CRVO patients) in a real-life setting, with a focus on treatment outcome and therapy schemes applied.

Results : The percentage of female patients were 51,7% and 45,2% in BRVO and CRVO, respectively. The entire population presented with a mean age of 70.8 and 71.7 years. Most patients were covered by public health insurance (BRVO: 81,2%; CRVO: 85,3%) and almost half of the patients were treatment-naïve (T-N) (BRVO: 46,4%; CRVO 46,7%). Mean BCVA at baseline was 58,2 (± 19,1) and 46,9 (± 26,0) letters for T-N BRVO and CRVO patients, respectively. After 24 months patients demonstrated a mean BCVA of 66,3 (± 27,6; BRVO) or 59,7 (± 30,4; CRVO) letters. An improvement of more than 15 letters was seen in 29,8% (BRVO) versus 36,4% (CRVO) of T-N patients. The decision to re-inject was most frequently based on OCT alone or OCT with BCVA assessment, rather than on BCVA assessment alone. “Fixed” treatment was the intended therapy scheme for most T-N patients in both, BRVO (54,2%) and CRVO (55,4%). During the observational period, however, the actual performed treatment appeared to shift towards a “monitor and extend” regimen (96.77% and 96.30% for BRVO and CRVO patients respectively).

Conclusions : We present data based on an interim analysis of the PACIFIC study, which provides real world evidence regarding the treatment of RVO patients with ranibizumab in Germany. Changes in visual acuity and preferences in therapy schemes used for German RVO patients will be discussed. These novel findings provide insights into how the implementation of ranibizumab treatment impacts visual outcomes for RVO patients.
