OBJECTIVE:This study aimed to demonstrate the clinical equivalence of biosimilar QL1205 and reference ranibizumab, Lucentis, in patients with neovascular age-related macular degeneration (nAMD).
DESIGN:This was a multicenter, double-masked, randomized, controlled phase III trial.
PARTICIPANTS:Treatment-naive patients with active nAMD were randomly assigned to receive QL1205 or reference ranibizumab.
METHODS:Patients received intravitreal injection of QL1205 or reference ranibizumab at a dose of 0.5 mg in the study eye once every 4 weeks for 48 weeks.
MAIN OUTCOME MEASURES:The primary end point was change in best-corrected visual acuity (BCVA) by ETDRS letters at week 8 compared with baseline level. Biosimilarity of QL1205 to reference ranibizumab was assessed with an equivalence range for the difference in BCVA letters between -3.49 and +3.49.
RESULTS:Between June 27, 2019 and June 8, 2021, 616 patients were randomized to the QL1205 group (n = 308) and the reference ranibizumab group (n = 308). The mean improvement of BCVA was +6.3 ± 9.13 ETDRS letters in the QL1205 group and +7.3 ± 8.82 ETDRS letters in the reference ranibizumab group at week 8. Both the 90% confidence interval (CI, -2.23 to 0.13) and 95% CI (-2.46 to 0.36) of the difference between the 2 treatment groups (P = 0.1434) were within the predefined equivalence range. Safety profiles were manageable in both groups.
CONCLUSIONS:QL1205 was biosimilar to reference ranibizumab regarding clinical efficacy, ocular and systemic safety, as well as immunogenicity and pharmacokinetics profiles in the treatment of patients with nAMD.
