Safety results
Summary: ocular adverse events and inflammation
The company's own 12-month results announcement reported only one subject with an ocular inflammation adverse event following exposure to bevacizumab-vikg, one related ocular serious adverse event in the bevacizumab-vikg arm (which resolved), and conjunctival hemorrhage as the most common ocular adverse event, and described the safety database as consistent with previously published bevacizumab safety results.

Study limitations
Summary: comparator dosing regimen
NORSE TWO compared monthly LYTENAVA dosing for one year against a ranibizumab regimen of three monthly loading doses followed by quarterly dosing, rather than against monthly ranibizumab throughout the study.
Authors' rationale for the unequal dosing regimens
Greater injection frequency as a possible driver of the higher treatment-related adverse event rate

Baseline characteristics
Summary: baseline visual acuity
The LYTENAVA arm had a mean baseline BCVA of 58.8 ETDRS letters.
Efficacy results
Summary: preliminary topline Week 8 result (November 2024 announcement)
Before the label's final analysis, the company's preliminary topline announcement reported a mean BCVA increase of “+4.2 letters” for ONS-5010 versus “+6.3 letters” for ranibizumab at Week 8, a difference it described as “-2.257 BCVA letters” (95% CI -4.044, -0.470); these preliminary figures differ slightly from the final Week 8 result in the approved label (Section 3.1.2.8.3 above).
Summary: BCVA gains over time and anatomic response
Mean BCVA improved progressively from baseline for the LYTENAVA arm: approximately +3.3 letters at month 1 (week 4), +4.2 letters at month 2 (week 8), and +5.5 letters at month 3 (week 12). Central retinal thickness decreased by approximately 123.9 microns in the LYTENAVA arm and 127.3 microns in the ranibizumab arm at week 12, an anatomic response the companies described as comparable between arms.
NORSE EIGHT week 8 BCVA result

Study limitations
Summary: primary endpoint not met at the pre-specified timepoint
NORSE EIGHT did not meet its pre-specified non-inferiority margin of -3.5 letters for the primary endpoint of mean change in BCVA at Week 8, although the LS mean difference at Week 12 (a secondary, non-primary timepoint) was within the non-inferiority margin.

Efficacy results
Summary: proportion gaining 15 or more letters at Month 11
The company's topline results announcement reported that 2 of 25 (8%) patients on the ONS-5010 arm and 5 of 23 (22%) patients on the ranibizumab arm gained more than 15 letters of best corrected visual acuity at Month 11, favoring ranibizumab numerically in this small trial.
Summary: treatment-naive subgroup
Among treatment-naive participants, the announcement reported 2 of 6 (33%) patients on the ONS-5010 arm and 4 of 13 (31%) patients on the ranibizumab arm gaining more than 15 letters at Month 11.
Health-related quality of life and patient-reported outcomes
No evidence found.
Safety results
Summary: safety comparable between arms
The company's topline results announcement reported no statistical differences in safety between ranibizumab and ONS-5010, and zero cases of ocular inflammation.
Study limitations
Summary: small comparator trial with results diverging from NORSE TWO
NORSE ONE was a small, 61-patient clinical experience trial in Australia, roughly 30 subjects per arm, in which a numerically smaller proportion of the ONS-5010 arm than the ranibizumab arm gained 15 or more letters, a result not repeated in the larger pivotal NORSE TWO trial.
NORSE THREE
Objective
Summary: purpose of the trial
The company's safety results announcement described NORSE THREE as an open-label safety study conducted to ensure an adequate number of safety exposures to ONS-5010 were available for the initial BLA submission to the FDA.

Safety results
Summary: adverse event incidence and comparison to prior bevacizumab safety data
Of the 197 enrolled patients, 20 (10%) experienced an adverse event in the study eye, most commonly associated with the injection procedure. The company described the safety profile as showing no unexpected trends and as consistent with prior published bevacizumab safety data, including the 2011 CATT study.
NORSE THREE absence of serious adverse events
Study limitations
Summary: open-label, single-arm design
NORSE THREE had no comparator or masking, so its adverse-event findings cannot be compared statistically with a control arm; it was designed only to add safety exposures to the overall LYTENAVA safety database ahead of the initial BLA submission.

Summary: ongoing, single-arm bridging study
NORSE SEVEN is a single-arm, open-label study comparing ONS-5010 supplied in vials versus a pre-filled syringe, with no ranibizumab or placebo comparator; ClinicalTrials.gov lists the trial as active, not recruiting, with an estimated primary completion date of December 2027, so its results are not yet available.
