Outcomes

Durability

The proportions of patients in the faricimab group on Q16W, Q12W, and Q8W dosing intervals in the TENAYA Japan subgroup:
• Q16W: 66.1% (41/62)
• Q12W: 22.6% (14/62)
• Q8W: 11.3% (7/62)

At week 48, 88.7% (55/62) of faricimab-treated patients were on Q12W or Q16W dosing intervals

Vision

Best-Corrected Visual Acuity (BCVA)
The adjusted mean (95% CI) BCVA change at Week 48 (Primary Outcome):
• Faricimab: +7.1 letters (95% CI: 4.6 to 9.7)
• Aflibercept: +7.7 letters (95% CI: 5.2 to 10.1)
• Difference: -0.5 letters (95% CI -4.1 to 3.0).

Outcomes

Conclusion

The TENAYA Japan subgroup analysis showed that faricimab up to Q16W had sustained efficacy and safety comparable to aflibercept Q8W. These findings align with global TENAYA and LUCERNE results.

Risk of Bias Assessment for Primary Outcome

Randomization Process
Low Risk

Low risk

Note: “Patients were randomized in a 1:1 ratio to faricimab up to Q16W or aflibercept Q8W using identification numbers assigned through an interactive voice- or web-based response system.”
“Baseline characteristics were generally balanced between treatment groups in the TENAYA Japan subgroup.”

Missing Outcome Data
Low Risk

Low risk

Note: The evidence that the primary outcome data analysis was not biased by the missingness: “Results are based on mixed model for repeated measures (MMRM) analysis; missing data were implicitly imputed by MMRM.”

Selection of the Reported Results
Low Risk

Low risk Note: registration with protocol

Deviations from Intended Observations
Low Risk

Low risk Note: This is a double-masked study. “The pre-planned TENAYA Japan subgroup analyses included all patients randomized in the TENAYA trial at sites in Japan.”

Measurement of the Outcome
Low Risk

Low risk Note: This is a double-masked study. “The outcome was averaged over the 3 time points to limit the impact of measurement variability and account for differences in time from the last dose received by patients across treatment groups on different dosing intervals.”
