flag The FDA granted Breakthrough Therapy Designation to Privosegtor, a drug showing promise in treating optic neuritis, a rare condition linked to multiple sclerosis.

flag The U.S. FDA has granted Breakthrough Therapy Designation to Privosegtor, a neuroprotective drug candidate by Oculis, for treating optic neuritis, a rare condition often tied to multiple sclerosis. flag Results from a Phase 2 trial showed patients receiving 3 mg/kg/day of Privosegtor plus steroids gained an average of 18 letters in low contrast visual acuity at three months, surpassing the 15-letter threshold for clinical significance. flag The drug also preserved retinal and optic nerve structure and reduced neurofilament levels, a marker of nerve damage. flag Side effects were mild, with headache and acne reported in a few patients, and no serious adverse events occurred. flag The designation supports ongoing global trials in optic neuritis and non-arteritic anterior ischemic optic neuropathy, with the first trial beginning in late 2025.
