Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disorder. Topical corticosteroids are the cornerstone of therapy in mild AD, whereas the JAK inhibitor upadacitinib is approved in the United States, Europe, and other countries for treating moderate-severe AD in adults and children over 12 years old whose disease is not adequately controlled with other systemic drugs, including biologics. The objective of this meta-analysis was to assess the overall efficacy and safety of upadacitinib in moderate to severe AD. All randomized controlled trials (RCTs) evaluating the efficacy and safety of upadacitinib in moderate to severe AD were included in the meta-analysis. The pooled analysis revealed a significant proportion of patients achieving Eczema Area and Severity Index-75 (EASI 75) (R.R. = 3.86; 95% CI = 3.12 to 4.78, p < 0.00001), EASI 100 (R.R. = 13.09; 95% CI = 7.40 to 23.17, p < 0.00001), Worst Pruritus Numerical Rating Score (WP-NRS) response (R.R. = 4.44; 95% CI = 3.72 to 5.29, p< 0.00001), and validated Investigator\'s Global Assessment (v-IGA) (RR = 5.96; 95% CI = 4.79 to 7.41, p < 0. 00001) in the upadacitinib arm compared to the placebo arm. Moreover, the pooled analysis also suggested that treatment-emergent adverse events (TAEs) were relatively higher with upadacitinib than with placebo, but were mild and easily manageable (R.R. = 1.15; 95% CI = 1.09 to 1.23, p<0.00001). This meta-analysis showed that upadacitinib had a significant beneficial effect and tolerable adverse effect profile in patients with moderate and severe AD. Dose regimens of 15 mg and 30 mg seemed to have similar benefits. However, further trials are needed to assess long-term efficacy and safety profile.

A 27-year-old man had ulcerative colitis (UC) 1 year prior and underwent a colectomy and two-stage ileal pouch-anal anastomosis for medically refractory UC 6 months ago. He visited our department with epigastric pain and discomfort, increased stool frequency, and bloody diarrhea. Esophagogastroduodenoscopy revealed continuous diffuse friable mucosa, erosions, and edema in the duodenum, and pouchoscopy revealed multiple ulcers and purulent mucus adhesions. Based on endoscopic and pathological findings, the patient was diagnosed with duodenitis associated with UC and pouchitis, for which he received oral prednisolone (40 mg/day) and ciprofloxacin. The frequency of stools and occurrence of bloody diarrhea reduced, and epigastric pain and discomfort improved after 2 weeks. However, when prednisolone was discontinued, the symptoms worsened, albumin level decreased, and C-reactive protein level increased. Following this, we administered a 20 mg prednisolone sodium phosphate enema once daily, and the patient\'s symptoms improved. However, the symptoms relapsed when the enema was discontinued. Assuming that the patient had steroid-dependent duodenitis associated with UC and pouchitis, we initiated upadacitinib. His symptoms improved within a few days, and biomarkers returned to normal after 1 month. Nine months after initiating the upadacitinib treatment, endoscopic remission was achieved in the mucosa of the duodenum and pouch. The patient has been in clinical remission for 1 year without any adverse events.

BACKGROUND: To evaluate the efficacy and safety of upadacitinib monotherapy versus methotrexate (MTX) monotherapy over 5 years among MTX-naïve patients with moderately to severely active rheumatoid arthritis (RA) in the long-term extension (LTE) of the phase 3 SELECT-EARLY trial.
METHODS: Patients were randomized to receive upadacitinib 15 mg or 30 mg or MTX. Patients who did not achieve CDAI remission and had < 20% improvement in tender and swollen joint counts at week 26 received rescue therapy (addition of MTX in the upadacitinib group and addition of upadacitinib in the MTX group). Efficacy assessments were evaluated over 5 years and are reported as observed (AO) for patients who received continuous monotherapy with upadacitinib 15/30 mg or MTX and by randomized group applying non-responder imputation (NRI). Treatment-emergent adverse events (TEAEs) per 100 patient-years were summarized over 5 years.
RESULTS: Of 945 patients randomized and treated, 775 (82%) completed week 48 and entered the LTE on study drug. Higher proportions of patients consistently achieved disease activity targets over 5 years with upadacitinib than MTX. In AO analyses, 53%/59% of patients attained CDAI remission with upadacitinib 15/30 mg versus 43% with MTX at week 260. NRI analyses showed better CDAI, DAS28(CRP), and ACR responses with upadacitinib relative to MTX at week 260 (all comparisons, nominal P < .001). Upadacitinib treatment also resulted in numerically greater inhibition of structural joint progression through week 260 compared to MTX. Most TEAEs, serious AEs, and AEs leading to discontinuation were numerically higher in patients receiving upadacitinib 30 mg. Rates of serious infections, herpes zoster, creatine phosphokinase elevation, nonmelanoma skin cancer, and neutropenia were numerically higher with upadacitinib than MTX. The observed safety profile of upadacitinib over 5 years was consistent with earlier trial results and integrated phase 3 safety analyses.
CONCLUSIONS: Upadacitinib showed better clinical responses versus MTX in patients with RA throughout the 5-year trial. Higher rates of several AEs were observed with upadacitinib, especially in the 30 mg group, compared to MTX. When used as monotherapy in MTX-naïve patients, the approved upadacitinib 15 mg dose showed better long-term efficacy versus MTX and an overall favorable benefit-risk profile.
BACKGROUND: NCT02706873.

UNASSIGNED: Conventional rosacea treatments are not uniformly pervasive, and the adverse reactions can potentially constrain their utility. The clinical use of JAK1 inhibitors upadacitinib and abrocitinib in the treatment of refractory rosacea has rarely been explored.
UNASSIGNED: We presented two cases of patients who received the JAK1 inhibitor upadacitinib and four cases of patients who received the JAK1 inhibitor abrocitinib for the treatment of refractory rosacea.
UNASSIGNED: The JAK1 inhibitors upadacitinib and abrocitinib may be promising medical options for patients with refractory rosacea. However, the long-term safety and efficacy of upadacitinib and abrocitinib require prospective controlled studies to assess them more comprehensively.

Introduction: Atopic dermatitis (AD) is a prevalent chronic inflammatory skin condition with a substantial impact on patients, particularly due to ocular involvement known as atopic keratoconjunctivitis (AKC). Current therapeutic approaches, such as dupilumab, often lead to conjunctivitis, prompting exploration of alternative treatments like upadacitinib. Methods: We collected dermatological and ophthalmological prospective clinical evaluations of six adults with moderate-to-severe AD, undergoing treatment with upadacitinib after discontinuation of dupilumab due to the onset of AKC during therapy and the worsening of dermatitis in particular in the head and neck region. Clinical evaluations, including EASI scores, itch and sleep NRS, DLQI, and ocular parameters, were performed at baseline (during screening assessment before switching to upadacitinib) and then at week 12 and week 24. Clinical evaluation of AKC was performed by a team of ophthalmologists. Results: Upadacitinib not only improved atopic dermatitis in terms of EASI, itching, and sleep NRS, but also demonstrated a notable reduction in ocular signs and symptoms, as indicated by the Visual Analogue Scale (VAS), the Efron scale, and the Ocular Surface Disease Index Symptom Severity (OSDISS) scores. Discussion: Our observation of common clinical practice underscores the substantial impact of biological and small-molecule therapies on AD, emphasizing the limitation posed by dupilumab-associated conjunctivitis. Switching to upadacitinib significantly improved both clinical and functional ocular outcomes, suggesting its potential as an alternative therapeutic option for AD patients with ocular involvement. Conclusion: The presented data provides insights into the complex interplay between systemic therapies and ocular manifestations in AD. Upadacitinib emerges as a promising option to address dupilumab-associated conjunctivitis, offering improved quality of life for patients.

Vernal keratoconjunctivitis is a persistent allergic ocular disease predominantly mediated by the T-helper 2 lymphocyte-associated immune response. The standard therapeutic approaches for vernal keratoconjunctivitis include topical corticosteroids and immunosuppressive eye drops. However, managing vernal keratoconjunctivitis with only topical treatments becomes challenging during seasonally exacerbated periods. Systemic treatments such as oral corticosteroids or cyclosporine may be alternative options. Recently, dupilumab\'s efficacy in refractory vernal keratoconjunctivitis treatment has been documented. Here, we report a case of refractory vernal keratoconjunctivitis coexisting with atopic dermatitis that rapidly improved after upadacitinib administration. An 18-year-old Japanese woman presented with atopic dermatitis, vernal keratoconjunctivitis, and hay fever. In winter, the patient experienced widespread erythema and escalated itching, leading to significant discomfort and insomnia. Owing to the difficulty in maintaining her current regimen, upadacitinib (15 mg), a Janus kinase inhibitor was initiated. After upadacitinib administration, the treatment-resistant vernal keratoconjunctivitis and erythema improved. Upadacitinib is beneficial in severe cases of atopic dermatitis. Consequently, in our case, upadacitinib may offer therapeutic benefits for refractory vernal conjunctivitis by improving the T-helper 1/2 type immune response, autoimmunity, and oxidative stress. To our knowledge, this is the first report suggesting the potential utility of upadacitinib in managing severe vernal conjunctivitis.

Atopic dermatitis is a chronic inflammatory skin disease that may progress to erythroderma in severe cases. Biologic agents such as dupilumab have recently become the mainstay of systemic treatment for moderate-to-severe cases, yet many patients remain refractory to therapy. Here, we present a case of erythrodermic atopic dermatitis, resistant to prednisone and dupilumab, with remarkably rapid achievement of remission following treatment with upadacitinib, an oral selective Janus kinase 1 inhibitor.

UNASSIGNED: Janus kinase (JAK) inhibition is a promising approach for treating vitiligo. We aimed to assess the efficacy and safety of upadacitinib, an oral selective JAK inhibitor, in adults with non-segmental vitiligo.
UNASSIGNED: This was a phase 2, multicentre, randomised, double-blind, placebo-controlled, dose-ranging study completed at 33 clinical centres in the United States, Canada, France, and Japan. Eligible patients were aged 18-65 years with non-segmental vitiligo and had a Facial Vitiligo Area Scoring Index (F-VASI) ≥0.5 and a Total Vitiligo Area Scoring Index (T-VASI) ≥5. Patients were randomly assigned (2:2:2:1:1) using an interactive response technology to receive upadacitinib 6 mg (UPA6), upadacitinib 11 mg (UPA11), upadacitinib 22 mg (UPA22), or placebo (PBO; preassigned to switch to either UPA11 or UPA22 in period 2) once daily for 24 weeks (period 1). For weeks 24-52 (period 2), patients randomly assigned to upadacitinib continued their treatment, and patients receiving PBO switched to their preassigned upadacitinib dose in a blinded fashion. The primary endpoint was the percent change from baseline in F-VASI at week 24. Efficacy was analysed in the intention-to-treat population, and safety was examined in all randomly assigned patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT04927975.
UNASSIGNED: Between June 16, 2021, and June 27, 2022, 185 patients (including 115 [62%] who were female and 70 [38%] who were male) were randomly assigned to UPA6 (n = 49), UPA11 (n = 47), UPA22 (n = 43), or PBO (n = 46). At week 24, the LS mean difference versus PBO in the percent change from baseline in F-VASI was -7.60 (95% CI -22.18 to 6.97; p = 0.3037) for UPA6, -21.27 (95% CI -36.02 to -6.52; p = 0.0051) for UPA11, and -19.60 (95% CI -35.04 to -4.16; p = 0.0132) for UPA22. The LS mean difference versus PBO in the percent change from baseline in T-VASI was -7.45 (95% CI -16.86 to 1.96; p = 0.1198) for UPA6, -10.84 (95% CI -20.37 to -1.32; p = 0.0259) for UPA11 and -14.27 (95% CI -24.24 to -4.30; p = 0.0053) for UPA22. Ongoing treatment with upadacitinib induced continuous skin repigmentation over time without reaching a plateau through week 52. The rates for study drug discontinuation and serious treatment-emergent adverse events (TEAEs) were higher in the UPA22 group than in the UPA11 and UPA6 groups. Eight serious TEAEs, including one death of unknown cause and one case of infiltrating lobular breast carcinoma, were reported through 52 weeks; only two serious TEAEs (coronary artery arteriosclerosis [UPA6 (n = 1)] and non-fatal ischemic stroke [UPA11 (n = 1)]) were deemed by the investigator to have a reasonable possibility of being related to study drug. The one case of breast cancer in the UPA11 group was deemed unrelated to study drug, and the one death of unknown cause in the UPA22 group was reviewed and adjudicated and was deemed to be unrelated to study drug. The most common TEAEs were COVID-19, headache, acne, and fatigue. No new safety signals were observed.
UNASSIGNED: Upadacitinib monotherapy led to substantial repigmentation of both facial and total body vitiligo lesions and may offer an effective treatment option for adults with extensive non-segmental vitiligo. Based on these findings, upadacitinib 15 mg is being investigated in adults and adolescents with non-segmental vitiligo in an ongoing phase 3 randomised controlled trial.

Monotherapy with a selective Janus kinase (JAK) inhibitor or intensive granulocyte and monocyte adsorptive apheresis (GMA) has been limited to patients with intractable ulcerative colitis (UC). No previous reports have described the efficacy including histopathological evaluations and the safety of combination therapy with upadacitinib (UPA) plus intensive GMA (two sessions per week) for intractable UC showing resistance to conventional agents and adalimumab. This retrospective study evaluated the 10-week clinical and histopathological efficacy of induction combination therapy with UPA plus intensive GMA in patients with intractable UC. Among eight patients (moderate UC, n = 1; severe UC, n = 7) who received combination therapy with UPA plus intensive GMA, 50.0% had achieved clinical remission by 10 weeks. Percentages of patients with histological-endoscopic mucosal improvement and mucosal healing at 10 weeks were 62.5% and 12.5%, respectively. After excluding one patient who discontinued treatment by week 10 because of intolerance for UPA, mean full Mayo score, endoscopic subscore and C-reactive protein concentration at baseline were 11.43 ± 0.37, 3 ± 0 and 1.29 ± 0.70 mg/dL, respectively. Corresponding values at 10 weeks were 2.28 ± 0.77 (P < 0.03), 1.14 ± 0.34 (P < 0.03) and 0.03 ± 0.008 mg/dL (P < 0.05), respectively. Adverse events of herpes zoster, temporary increase in creatinine phosphokinase and anemia were observed in one patient each. One patient discontinued combination therapy at week 4 because of temporary taste abnormality due to UPA. Combination comprising UPA plus intensive GMA appears likely to achieve satisfactory induction of clinical remission and histopathological improvement for patients with intractable UC for whom conventional agents and anti-tumor necrosis factor-α antibody have failed.
