NCT06671938 · Phase 2 · completed
This is a randomized, double-blind, placebo-controlled trial, but it enrolled only 38 participants split across dose cohorts, its primary endpoint measures adverse-event incidence rather than efficacy, and results have not yet been posted, so no conclusion about benefit can be drawn.
Prasinezumab
Developed by Roche and partners
No graded featured trial for this indication yet; the grade above reflects that absence, not a judgment.
