NORTH CHICAGO, Ill., Oct. 29, 2025 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced positive topline results from two replicate Phase 3 studies evaluating the safety and efficacy of upadacitinib (RINVOQ®;15 mg, once daily in adult and adolescent patients living with non-segmental vitiligo (NSV).1 NSV, the most common form of vitiligo (occurring in over 90% of patients), is characterized by symmetrical and bilateral white patches on both sides of the body.2-4
"Vitiligo is more than a skin condition – it's a chronic autoimmune disease that can deeply affect a person's confidence, identity and daily life," said Kori Wallace, M.D., Ph.D., vice president, global head of immunology clinical development, AbbVie. "There are no approved systemic medical therapies for achieving re-pigmentation in vitiligo. These Phase 3 results represent a significant milestone in AbbVie's commitment to supporting patients and expanding our immunology portfolio to deliver innovative solutions."
The Total Vitiligo Area Scoring Index (T-VASI) is a tool that measures the extent of de-pigmentation over the entire body while F-VASI measures de-pigmentation of the face, an area among the most visible and psychosocially impactful for people living with NSV. Across both studies approximately 70% of subjects had T-VASI > 10 at baseline. In both studies, upadacitinib achieved the co-primary endpoints of T-VASI 50 (≥50% reduction from baseline in T-VASI score) and F-VASI 75 (≥75% reduction from baseline in F-VASI score) at week 48 versus placebo. Across both studies, statistically significant differences were observed with upadacitinib versus placebo in key ranked secondary endpoints, including F-VASI 50 at week 48.1
Key efficacy results are summarized below:
| Phase 3 Efficacy Results1 | ||||
| Study 1 | Study 2 | |||
| Upadacitinib 15 mg (N=206), % | Placebo (N=102), % | Upadacitinib 15 mg (N=205), % | Placebo (N=101), % | |
| Co-Primary Endpoints | ||||
| T-VASI 50 at week 48 | 19.4 | 5.9 | 21.5 | 5.9 | 
| F-VASI 75 at week 48 | 25.2 | 5.9 | 23.4 | 6.9 | 
| Secondary Endpoints | ||||
| F-VASI 50 at week 48 | 48.1 | 12.7 | 43.4 | 12.9 | 
"For many people living with vitiligo, the journey is marked by uncertainty, frustration and a lack of medicines that can treat the disease systemically," said Thierry Passeron, M.D., Ph.D., professor and chair, Department of Dermatology, Université Côte d'Azur. "These positive results indicate that targeting the underlying inflammation may offer a systemic treatment option which could help patients achieve visible results."
The safety profile of upadacitinib in both studies was generally consistent with that observed in approved indications. No new safety signals were observed. Across both studies, the most frequent treatment-emergent adverse events (TEAEs) in the 48 weeks upadacitinib treatment groups were upper respiratory tract infection, acne and nasopharyngitis. In study 1, treatment-emergent serious adverse events (TESAEs) occurred in 3.9% and 4% of patients in the upadacitinib 15 mg and placebo groups, respectively. In study 2, TESAEs occurred in 2% and 1% of patients in the upadacitinib 15 mg and placebo groups, respectively. There were no adjudicated cases of any major cardiovascular event (MACE) or venous thromboembolism (VTE) in the studies. Three malignancy events were reported: one was reported in both placebo groups (1% each) of studies 1 and 2, and one was reported in the upadacitinib 15 mg group (0.5%) in study 1 (genital neoplasm). There were no deaths reported in the upadacitinib treated groups across both studies. There was one death reported in the placebo group in study 2.1
Use of upadacitinib in NSV is not approved and its safety and efficacy have not been evaluated by regulatory authorities.
About Vitiligo
Vitiligo is a chronic autoimmune disease characterized by the loss of pigment-producing cells (melanocytes), resulting in white patches of skin that can appear anywhere on the body and at any time. It is the most common depigmenting disorder worldwide, affecting approximately 0.5% to 2.3% of the global population. Non-segmental vitiligo (NSV) is the predominant form of the disease, accounting for roughly 84% of cases. NSV typically presents as symmetrical, bilateral patches on both sides of the body. While location varies, many patients report patches on critical areas such as the face, feet, hands and groin. The daily challenges of living with vitiligo can lead to mental health conditions, with a high prevalence of depression and anxiety.
About Viti-Up Clinical Trials
Upadacitinib M19-044 was conducted under a single protocol encompassing two replicate Phase 3 studies (Study 1 and Study 2) with independent randomization, investigative sites, data collection, analysis and reporting for each study. The trials were designed to evaluate the efficacy, safety and tolerability of upadacitinib in adult and adolescent patients (ages 12 and older) living with non-segmental vitiligo (NSV) who were eligible for systemic therapy. In Period A of both studies, participants were randomized in a 2:1 ratio to receive either upadacitinib 15 mg once daily or placebo for 48 weeks. Participants who completed Period A were eligible to enter Period B, a 112-week open-label extension in which all patients received upadacitinib 15 mg once daily. In total, Study 1 and Study 2 Periods A and B span 160 weeks. The two trials randomized 614 participants with NSV across 90 sites worldwide. More information on these trials can be found at www.clinicaltrials.gov (NCT06118411).
The co-primary endpoints were based on the achievement of Total Vitiligo Area Scoring Index (T-VASI) 50, defined as at least 50% reduction in T-VASI from baseline, at week 48, and the achievement of Facial Vitiligo Area Scoring Index (F-VASI) 75, defined as at least 75% reduction in F-VASI from baseline, at week 48 with the treatment of upadacitinib 15 mg compared with placebo in adults and adolescents with NSV.
The secondary endpoints include the achievement of F-VASI 50, defined as at least a 50% reduction in F-VASI from baseline, at week 48, and the achievement of F-VASI 75, defined as at least a 75% reduction in facial vitiligo area from baseline, at week 24. These endpoints were designed to assess the degree and timing of re-pigmentation on the face, an area among the most visible and psychosocially impactful for people living with NSV. Study 1 also included an analysis using 3D digital imaging to assess facial repigmentation, measured in a subset of the study population.
About RINVOQ® (upadacitinib)
Discovered and developed by AbbVie scientists, RINVOQ is a JAK inhibitor that is being studied in several immune-mediated inflammatory diseases. In human leukocyte cellular assays, RINVOQ inhibited cytokine-induced STAT phosphorylation mediated by JAK1 and JAK1/JAK3 more potently than JAK2/JAK2 mediated STAT phosphorylation. The relevance of inhibition of specific JAK enzymes to therapeutic effectiveness and safety is not currently known.
Upadacitinib (RINVOQ) is being studied in Phase 3 clinical trials for alopecia areata, hidradenitis suppurativa, Takayasu arteritis, systemic lupus erythematosus and vitiligo.
