Purpose: The Phase 3 Mylight study was designed to confirm clinical equivalence of proposed biosimilar aflibercept (SOK583A1; Sandoz [proposed biosimilar aflibercept, SDZ-AFL]) to its reference biologic (Eylea; Regeneron Pharmaceuticals, Inc; Bayer AG [reference aflibercept, Ref-AFL]).
Method: Mylight was a prospective, double-masked, 2-arm, parallel Phase 3 study. Participants with neovascular age-related macular degeneration were randomized 1:1 to receive eight injections of SDZ-AFL (n = 244) or Ref-AFL (n = 240) over 48 weeks. The primary endpoint was mean change in best-corrected visual acuity score from baseline to Week 8. Secondary endpoints included anatomical outcomes, best-corrected visual acuity at Weeks 24 and 52, safety, and pharmacokinetics.
Results: Similarity in mean change in best-corrected visual acuity score was established between SDZ-AFL (n = 235) and Ref-AFL (n = 226) at Week 8 (difference: -0.3 [90% CI, -1.5 to 1.0]) and Week 52. No clinically meaningful differences occurred between groups in anatomical outcomes. Safety profiles were similar, with comparable incidences of treatment-related adverse events (SDZ-AFL: 2.5%; Ref-AFL: 2.9%). The incidence of anti-drug antibodies was similar between groups. Systemic free aflibercept concentrations 24 hours postdose were low and comparable between SDZ-AFL and Ref-AFL.
Conclusion: Proposed biosimilar aflibercept matched reference aflibercept in efficacy, safety, and pharmacokinetics in participants with neovascular age-related macular degeneration. Therefore, this Phase 3 study confirmed biosimilarity of SDZ-AFL to Ref-AFL.

Purpose: The inclusion of ranibizumab biosimilars into National Health Service England commissioning recommendations published in 2022 created a need for expert guidance to optimize treatment outcomes in patients with neovascular age-related macular degeneration (nAMD) who otherwise may not have received first-line ranibizumab. This article provides a consensus treatment pathway supporting timely identification and management of a suboptimal response to these therapies, thereby aiming to facilitate clinically meaningful outcomes and efficient management of service capacity under specific circumstances where ranibizumab biosimilars may be initiated as a first-line treatment.
Methods: Two structured round-table meetings of UK medical retina specialists were held in person and virtually on September 22 and November 3, 2022, respectively.

Introduction: ABP 938 is being developed as a biosimilar to Eylea (aflibercept reference product [RP]), an anti-vascular endothelial growth factor (VEGF) drug used in the management of retinal diseases. Previously, a comparative analytical similarity assessment demonstrated that ABP 938 and aflibercept RP have the same amino acid sequence and exhibit similar higher-order structure and biological activity. The nonclinical studies described here were designed to assess the in vitro pharmacology and the in vivo pharmacokinetics (PK), toxicokinetics (TK), and safety profiles of ABP 938 compared to aflibercept RP.

Wet age-related macular degeneration (AMD) is an acquired degeneration of the retina that can lead to central vision impairment. It is primarily treated with intravitreal injections of vascular endothelial growth factor inhibitors. Although vascular endothelial growth factor inhibitors can effectively prevent progression of vision loss in many patients, they require ongoing regular administration and are therefore associated with considerable treatment burden.
