- Brepocitinib 45 mg once-daily achieved statistically significant benefit compared to placebo on the primary and all key secondary endpoints for each of CLARITY-1 and CLARITY-2, the two identical Phase 3 trials comprising the CLARITY program in NIU
- Median time to treatment failure for brepocitinib patients was greater than 48 weeks in both studies, compared with ~12 weeks on placebo in each study (p<0.0001 in both studies), including 40 weeks of steroid-free treatment, setting a new bar for time to failure and steroid-sparing benefit in NIU
- Pooled across the CLARITY studies, 62% of patients on brepocitinib achieved steroid-free quiescence at Week 48, compared with 20% on placebo (p<0.0001), with similar results in each study
- Of patients that entered the CLARITY studies (pooled) with macular edema, 42% of eyes on brepocitinib achieved resolution of macular edema at Week 48, compared with 4.8% on placebo (p<0.0001), with similar results in each study
- The magnitude and breadth of benefit observed across every ranked endpoint, compared with results reported in registrational trials of existing NIU therapies, suggest brepocitinib has the potential to be the most effective systemic, non-steroid treatment option for NIU
- Safety data consistent with prior brepocitinib clinical trials; no new safety signals or findings
- Priovant intends to file a supplemental New Drug Application (sNDA) for brepocitinib for the treatment of NIU in the first half of calendar year 2027
- Roivant will host an investor call to discuss these updates today, October 21, 2026, at 8:00 a.m. ET
BASEL, Switzerland and LONDON and NEW YORK and DURHAM, N.C., Oct. 21, 2026 (GLOBE NEWSWIRE) -- Roivant (Nasdaq:ROIV) and Priovant Therapeutics today announced positive results from the Phase 3 CLARITY program evaluating brepocitinib in non-infectious uveitis (NIU). Brepocitinib met the primary endpoint for both the CLARITY-1 and CLARITY-2 studies. Brepocitinib also achieved statistically significant and clinically meaningful benefit on all key secondary endpoints, including measurements of sustained steroid-free quiescence at Week 48, chorioretinal vascular leakage, resolution of macular edema and patient-reported visual functioning. These results were achieved despite a substantially more aggressive steroid taper than precedent NIU trials.
“Today marks a potential turning point for the field of uveitis and for the patients and physicians who have waited nearly a decade for a new systemic, non-steroid treatment option. The phenomenal results from the Phase 3 CLARITY program suggest that brepocitinib could meaningfully change how we treat non-infectious uveitis across multiple etiologies,” said Quan Dong Nguyen, MD, MSc, FAAO, FARVO, FASRS, Professor of Ophthalmology, Professor of Medicine (Immunology/Rheumatology), and Professor of Pediatrics (Rheumatology) at the Byers Eye Institute and Stanford University School of Medicine, President of the International Ocular Inflammation Society (IOIS), and Executive Vice President of the Foster Ocular Immunology Society (FOIS). “Even with a much faster taper of oral prednisone, patients treated with brepocitinib in CLARITY demonstrated highly differentiated benefits across the primary and all key secondary endpoints, including quiescence, resolution of macular edema and improvement in chorioretinal inflammation. This is the kind of outcome that can redefine expectations for an entire field. To see this breadth of benefit across disease control, macular edema and visual functioning is tremendously exciting for those of us who care for these patients.”
NIU, a debilitating ocular inflammation, is one of the leading causes of blindness among the working age population. Undertreated NIU can result in permanent vision loss. NIU is frequently associated with ocular pain, floaters and visual impairment across multiple domains (acuity, peripheral vision, color recognition, ability to focus on moving objects, night vision, etc.) that can interfere with everyday activities including reading the newspaper, driving, socializing, working and independent self-care. NIU is estimated to affect 70,000 to 190,000 adults in the United States.
CLARITY Study Design and Data
The CLARITY program enrolled 371 patients across two identical studies, CLARITY-1 and CLARITY-2. Patients were randomized 1:1 to once-daily brepocitinib 45 mg or placebo for a 48-week double-masked treatment period. All patients received an 8-week oral corticosteroid (OCS) regimen of 60 mg/day for 2 weeks followed by a mandatory 6-week steroid taper to zero. The primary endpoint was time to treatment failure, assessed from Week 6 through Week 48.
Time to treatment failure in CLARITY-1 and CLARITY-2 (Kaplan-Meier estimates, brepocitinib vs. placebo) is captured below:
Brepocitinib demonstrated consistent benefits on preventing treatment failure across key subgroups, including intermediate, posterior, and panuveitis; patients with and without prior TNFi experience; and multiple etiologies of uveitis, including idiopathic disease, birdshot chorioretinopathy, and sarcoidosis.
Pre-specified multiplicity controlled secondary endpoints in the CLARITY trials included sustained steroid-free quiescence, improvement in chorioretinal vascular leakage as assessed through wide-field fluorescein angiography (FA), resolution of macular edema, and improvement in patient-reported visual functioning (NEI VFQ-25 overall composite score).
Results on the primary and key secondary endpoints are captured below:

Safety and Regulatory Submissions
Brepocitinib was generally well tolerated during the treatment period. Most events were mild or moderate in severity, and only 3% of participants discontinued treatment due to an AE. The observed safety profile in the trials was consistent with the known safety profile of brepocitinib, with no new safety signals observed.
Priovant intends to file a supplemental New Drug Application (sNDA) for brepocitinib for treatment of NIU in the first half of calendar year 2027.
“The breadth and magnitude of benefit seen in the CLARITY studies position brepocitinib to potentially set a new standard for the treatment of non-infectious uveitis,” said Ben Zimmer, CEO of Priovant. “With LISRAYA now commercially available for adults with dermatomyositis, we see NIU as the potential next pillar of a leading rare disease immunology franchise. I would like to thank all of the investigators and patients who participated in the CLARITY trials, without whom this moment would not be possible.”
