Study Overview This Phase 1 Biogen study, officially titled “A Phase 1, Randomized, Open-Label, Single-Dose, Crossover, Bioequivalence Study of Omaveloxolone Tablets for Oral Suspension Versus Capsules in Healthy Adult Participants,” aims to see whether a new tablet-for-suspension form of BIIB141 (omaveloxolone/SKYCLARYS) behaves in the body the same way as the current capsule. The focus is on how the drug is absorbed and processed in healthy adults, and on basic safety signals. The work matters because an easier-to-take form could broaden use in Friedreich’s ataxia and support longer-term revenue durability for Biogen. Study Design This is an interventional, Phase 1, randomized, open-label, two-period crossover study in healthy volunteers. All participants receive both forms of the drug in different orders, with a washout period between doses. There is no placebo and no blinding. The main purpose is treatment-focused bioequivalence: to compare how much drug gets into the bloodstream and how fast, and to confirm that both forms perform similarly while monitoring basic safety and tolerability.
