How could OCS's positive ACUITY trial data affect the FDA's regulatory review?
OCS's positive trial data may influence FDA review of Privosegtor The presentation of new translational data from the Phase 2 ACUITY trial provides objective evidence of Privosegtor's neuroprotective potential in acute optic neuritis. This data, which evaluates biomarkers like plasma neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP), strengthens Oculis Holding AG's case for further regulatory consideration. By demonstrating improved visual function and anatomical preservation, the company is better positioned to file an Investigational New Drug (IND) application for Privosegtor in acute multiple sclerosis relapses, which the FDA would then review.

Oculis Holding AG announced that new biomarker information from the Phase 2 ACUITY trial of Privosegtor will be presented at the 10th Joint ACTRIMS-ECTRIMS Meeting in Toronto, Canada, on October 21-23, 2026. The presentation will detail analyses of plasma neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) in patients with acute optic neuritis. Céline Louapre is the principal investigator of the ACUITY Phase 2 trial.
The full event1independent outlet -
The positive results from the ACUITY trial, which showed Privosegtor's neuroprotective potential, support Oculis's plan to file an IND for Privosegtor for the treatment of acute MS relapses. The FDA is the regulatory body responsible for reviewing these IND submissions and determining the path for drug development.

The facts so far
As reported. Each one links to where it comes from.
- The ACUITY Phase 2 trial evaluated plasma NfL and GFAP as biomarkers of neuroaxonal injury and neuroinflammation in acute optic neuritis.manilatimes.net
- Privosegtor was granted Breakthrough Therapy designation from the FDA and Priority Medicines (PRIME) designation from the EMA.manilatimes.net
- Positive results from the ACUITY Phase 2 trial showed Privosegtor’s neuroprotective potential, evidenced by improved visual function.manilatimes.net

Why it matters
Optic neuritis is a rare condition that can lead to permanent visual impairment, and currently, there is no specific therapy approved to prevent vision loss after an acute episode. Privosegtor is a novel peptoid small-molecule candidate that has shown promise in protecting retinal ganglion cells, making it a high-stakes candidate in the neuro-ophthalmology field.
OCS has already secured significant regulatory milestones, including Breakthrough Therapy designation from the FDA and PRIME designation from the EMA. This existing regulatory momentum, combined with the new translational data, positions the company to advance its pipeline and potentially become the first neuroprotective therapy for optic neuritis and related neuro-axonal diseases.
