Brief Summary
This is a phase 3, randomized, multicenter, vehicle-controlled, double-masked study to evaluate the efficacy and safety of intranasal cenegermin compared with vehicle control in adult participants with NAION. Approximately 272 participants who meet all eligibility criteria will be randomly assigned in a 1:1 ratio to receive either cenegermin treatment (Group 1) or the vehicle control (Group 2).

Outcome Measures
Primary Outcomes (1)
Achievement of ≥ 15 letter increase in Best Corrected Visual Acuity (BCVA), assessed in each individual participant, measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart
Improvement in visual acuity defined as a \>=15 letter increase in BCVA using ETDRS chart.
Baseline to Week 24
Secondary Outcomes (5)
Change from baseline in visual field mean sensitivity in decibels
Baseline through Week 24
Change from baseline in BCVA as measured by the ETDRS chart
Baseline through Week 24
Change from baseline in visual field mean sensitivity, in a prespecified region consisting of at least 5 separate loci on visual field testing
Baseline through Week 24
Change from baseline in ganglion cell layer-inner plexiform layer (GCL-IPL) thickness (micrometer [μm]) on optical coherence tomography (OCT).
Baseline through Week 24
Incidence of ocular and non-ocular adverse events
Through Week 24
Study Arms (2)
Cenegermin
EXPERIMENTALParticipants will be administered with cenegermin spray in each nostril.
Vehicle
PLACEBO COMPARATORParticipants will be administered with vehicle spray in each nostril.
Interventions
Eligibility Criteria
You may qualify if:
- A clinical diagnosis of unilateral NAION in the study eye with symptom onset within 14 days prior to the planned date for first dose administration.
- A BCVA score in the study eye of ≥ 15 letters and ≤ 65 letters measured using the ETDRS chart.
- Sufficiently clear ocular media and adequate pupil dilation to enable assessment of the optic nerve and retina in both eyes.
You may not qualify if:
- Bilateral NAION or sequential NAION with fellow eye involvement within 6 weeks of study eye involvement.
- Clinical evidence of temporal arteritis (giant cell arteritis) signs or symptoms.
- Abnormal laboratory findings suggestive of temporal arteritis (giant cell arteritis), in the absence of a known acute cause
- Pain with eye movement
- Intraocular pressure (IOP) greater than 25 mmHg in the study eye or history of glaucoma in the study eye.
- Intermediate age-related macular degeneration (AMD) with subfoveal drusen, exudative AMD, or geographic atrophy in the study eye.
