Is this trial a fit for you?

Likely a good fit

Adults with unilateral NAION diagnosed within 14 days, ETDRS letter score between 15 and 65 in the affected eye, and sufficient ocular media clarity.

Probably not a fit

Patients with bilateral NAION, signs of temporal arteritis, high intraocular pressure or glaucoma in the study eye, or certain AMD conditions may not benefit and are excluded.

What this trial studies

This is a Phase 3, randomized, multicenter, double-masked trial comparing intranasal cenegermin to vehicle in adults with unilateral NAION. About 272 participants will be assigned 1:1 to receive either cenegermin or vehicle, to assess safety and efficacy. Eligible participants have recent NAION onset within 14 days, a measurable visual acuity range, and adequate ocular clarity for examinations. Key exclusions include bilateral involvement, signs of temporal arteritis, high IOP or glaucoma in the study eye, and certain AMD conditions. The study is led by Dompé Farmaceutici with multiple ophthalmology centers in California.

Why it matters

Potential benefit: If successful, cenegermin could improve vision or halt further loss in NAION and advance treatment options for this acute optic neuropathy.

How similar studies have gone: Previous approaches in optic neuropathies have shown mixed results; this trial tests a novel intranasal therapy specifically for NAION in a robust Phase 3 design.

Key Inclusion Criteria:

1. 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.
2. A BCVA score in the study eye of ≥ 15 letters and ≤ 65 letters measured using the ETDRS chart.
3. Sufficiently clear ocular media and adequate pupil dilation to enable assessment of the optic nerve and retina in both eyes.

Key Exclusion Criteria:

1. Bilateral NAION or sequential NAION with fellow eye involvement within 6 weeks of study eye involvement.
2. Clinical evidence of temporal arteritis (giant cell arteritis) signs or symptoms.
3. Abnormal laboratory findings suggestive of temporal arteritis (giant cell arteritis), in the absence of a known acute cause
4. Pain with eye movement
5. Intraocular pressure (IOP) greater than 25 mmHg in the study eye or history of glaucoma in the study eye.
6. Intermediate age-related macular degeneration (AMD) with subfoveal drusen, exudative AMD, or geographic atrophy in the study eye.

Note: Additional inclusion/exclusion criteria apply, as defined in the protocol.
