In this multicentric real-world observational retrospective study, we evaluated the efficacy and safety of dupilumab for atopic dermatitis in children <6 years of age who underwent a minimum of 16 weeks of therapy. The analysis focused on EASI (Eczema Area and Severity Index), CDLQI (Children's Dermatology Life Quality Index), and Itch NRS (Numeric Rating Scale) changes from baseline to 4, 16, 24, 48, 72, and 96 weeks of follow-up (when available). Overall 24 children were included, with a mean age of 4.4 years. The baseline mean EASI among these patients was 26.7 (range 11.2-42.5). Since week 16 of therapy, all patients achieved and sustained at least 50% (EASI-50) atopic dermatitis improvement from baseline for the remainder of the follow-up period. At week 16, the mean EASI was 4.6 (0.8-13.1), EASI-75 reached 75% and EASI-90 38% of the patients. Within the initial 16 weeks of dupilumab treatment, 50% of patients experienced at least one adverse event, none of which were deemed severe. Conjunctivitis was among the most common adverse events (8.3%). In conclusion, dupilumab exhibited favorable tolerability, efficacy, and safety in children diagnosed with atopic dermatitis who were below the age of 6.

Lenvatinib plus pembrolizumab significantly improved efficacy versus sunitinib in treatment of advanced renal cell carcinoma (aRCC) in the phase 3 CLEAR study. We report results of an exploratory post hoc analysis of tumor response data based on baseline metastatic characteristics of patients who received lenvatinib plus pembrolizumab versus sunitinib, at the final overall survival analysis time point of CLEAR (cutoff: July 31, 2022). Treatment-naïve adults with aRCC were randomized to: lenvatinib (20 mg PO QD in 21-day cycles) plus pembrolizumab (n = 355; 200 mg IV Q3W); lenvatinib plus everolimus (not reported here); or sunitinib (n = 357; 50 mg PO QD; 4 weeks on/2 weeks off). The most common (lenvatinib plus pembrolizumab; sunitinib, respectively) metastatic site was lung (71.0%; 63.9%), followed by lymph node (45.6%; 43.7%), bone (22.5%; 24.9%), and liver (17.7%; 19.6%). Across treatment arms, ≥65% had two or more metastatic organs/sites involved, >80% of patients had nontarget lesions, and ~45% had baseline sums of diameters of target lesions ≥60 mm. Lenvatinib plus pembrolizumab demonstrated greater progression-free survival, objective response rate, and duration of response versus sunitinib across evaluable subgroups regardless of site or size of baseline metastasis or number of metastatic sites at baseline. Overall survival generally trended to favor lenvatinib plus pembrolizumab versus sunitinib; and tumor shrinkage was greater across sites (lung, lymph node, liver, and bone) for patients in the lenvatinib-plus-pembrolizumab arm versus the sunitinib arm. These results further support lenvatinib plus pembrolizumab as a standard-of-care in patients with aRCC regardless of site or size of baseline metastasis or the number of metastatic sites.

Our aim is to determine the number of leukocytes, T lymphocytes and B lymphocytes and the expression of activation markers CD200 and CD23 on B lymphocytes in atopic dermatitis (AD) patients (treated and not treated with dupilumab) during the pollen season. We examined 29 patients not treated with dupilumab, 24 patients treated with dupilumab and 40 healthy subjects as a control group. The count of T and B lymphocytes and their subsets were assessed by flow cytometry. The non-parametric Kruskal-Wallis one-factor analysis of variance with post hoc by Dunn's test with Bonferroni's modification was used for statistical processing. Although there was a significant improvement in skin findings in patients treated with dupilumab, the changes in immunological profile show a persistent altered immune response characterized by dysregulation and overactivation of B lymphocytes. Dupilumab therapy leads to normalization of relative T regulatory lymphocytes and total memory B lymphocytes and to decreased count of absolute CD8+ T lymphocytes. Why carry out this study?Studies investigating the immunological profile of atopic dermatitis (AD) patients during the pollen season are rare. There are no studies investigating the count of B lymphocytes (CD5+, CD22+ and CD73+ B lymphocytes) and the expression of activation markers CD23 and CD200 on B lymphocytes and on their subsets during pollen season in AD patients treated and non-treated with dupilumab therapy.What was learned from the study?In atopic dermatitis (AD) patients with and without dupilumab therapy, we confirmed the significantly higher count of absolute neutrophils, absolute monocytes, absolute eosinophils, absolute basophils, non-switched B lymphocytes, transitional B lymphocytes, CD23 memory, naive, non-switched, switched and total CD23 B lymphocytes, the relative count of CD200 memory and CD200 switched B lymphocytes.In dupilumab treated patients, we confirmed the significantly higher count of relative eosinophils, relative CD16+ eosinophils, relative CD200 non-switched B lymphocytes and lower count of absolute CD8+ T lymphocytes. Further studies should focus on investigating the effect of dupilumab on CD8+ T lymphocytes and their subpopulations.In patients without dupilumab therapy, we confirmed the significantly higher count of relative neutrophils, relative T regulatory lymphocytes and total memory B lymphocytes.The changes in the count of CD5+, CD22+ and CD73+ B lymphocytes were not observed during pollen season in both groups of AD patients.

BACKGROUND AND OBJECTIVES: Patients with multiple sclerosis (MS) may demonstrate better disease control when treatment is initiated on high-efficacy disease-modifying therapies (DMTs) from onset. This subgroup analysis assessed the long-term efficacy and safety profile of the high-efficacy DMT ocrelizumab (OCR) as first-line therapy for early-stage relapsing MS (RMS). METHODS: Post hoc exploratory analyses of efficacy and safety were performed in a subgroup of treatment-naive patients with RMS who received ≥1 dose of OCR in the multicenter OPERA I/II (NCT01247324/NCT01412333) studies. Patients were randomized to OCR or interferon β-1a for 96 weeks (double-blind controlled treatment period [DBP]), before switching to OCR in the open-label extension (OLE). Efficacy assessments included no evidence of disease activity (NEDA-3), 24-week confirmed disability progression (CDP), MRI lesion activity, change in whole-brain volume; with safety outcomes assessed over a 9-year treatment period. RESULTS: Overall, 757 patients were included (interferon-treated n = 382, mean age 36.3 years, 65.7% female; OCR-treated n = 375, mean age 35.5 years, 64.0% female); 505 of 757 (66.7%) completed 9 years of follow-up. The difference in NEDA status between OCR-treated and interferon-treated patients achieved during the DBP (72.5% and 43.8%, respectively, odds ratio 3.48, 95% CI 2.52-4.81) was maintained throughout the 7-year OLE (48.2% vs 25.7%; odds ratio 2.72, 95% CI 1.94-3.82). No 24-week CDP was observed in 78.7% of OCR-treated patients over 9 years. Brain volume loss over the entire study period remained numerically higher among patients starting OCR later (p = 0.09 at OLE at week 336). During the DBP, safety profiles in both groups were similar; no new safety signals were observed during the OLE. Over >9 years of continuous OCR treatment, the rate of infections remained low and stable over time. DISCUSSION: A higher proportion of OCR-treated patients achieved NEDA status compared with interferon-treated patients during the DBP, which was maintained throughout the OLE. After switching to OCR, disability accrual and brain volume loss among interferon-treated patients became similar to the OCR-OCR group, but disability and brain volume loss accrued during interferon treatment were not recovered. Possible study limitations include assessment bias due to unmaintained blinding during the OLE. These data support OCR as first-line therapy for these patients. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that OCR delays disease progression in treatment-naïve patients with early-stage RMS.

Nanrilkefusp alfa (nanril; SOT101) is an interleukin (IL)-15 receptor βγ superagonist that stimulates natural killer (NK) and CD8+ T cells, thereby promoting an innate and adaptive anti-tumor inflammatory microenvironment in mouse tumor models either in monotherapy or combined with an anti-programmed cell death protein 1 (PD-1) antibody. In cynomolgus monkeys, a clinical schedule was identified, which translated into the design of a phase 1/1b clinical trial, AURELIO-03 (NCT04234113). In 51 patients with advanced/metastatic solid tumors, nanril increased the proportions of CD8+ T cells and NK cells in peripheral blood and tumors. It had a favorable safety profile when administered subcutaneously on days 1, 2, 8, and 9 of each 21-day cycle as monotherapy (0.25-15 μg/kg) or combined (1.5-12 μg/kg) with the anti-PD-1 pembrolizumab (200 mg). The most frequent treatment-emergent adverse events were pyrexia, injection site reactions, and chills. Furthermore, early clinical efficacy was observed, including in immune checkpoint blockade-resistant/refractory patients.

OBJECTIVE: The aim of this study was to evaluate the efficacy and safety of intravenous (IV) secukinumab in patients with active psoriatic arthritis (PsA). METHODS: INVIGORATE-2 (NCT04209205) was a randomized, placebo-controlled, phase 3 trial. Patients with active PsA were randomized 1:1 to receive IV secukinumab (6 mg/kg at baseline followed by 3 mg/kg every four weeks [q4w]) or placebo. At week 16, patients randomized to placebo were switched to IV secukinumab (3 mg/kg q4w), and patients who received IV secukinumab continued treatment through week 52. The primary efficacy endpoint was achievement of 50% improvement in American College of Rheumatology response criteria (ACR50) at week 16. Efficacy and safety were evaluated through weeks 52 and 60, respectively. RESULTS: Among 191 patients randomized to IV secukinumab and 190 to placebo/IV secukinumab, 177 (92.7%) and 170 (89.5%) completed the entire study period, respectively. A significantly higher proportion of patients who received IV secukinumab versus placebo achieved ACR50 at week 16 (31.4% vs 6.3%; adjusted P < 0.0001). All secondary efficacy endpoints were met at week 16 (all adjusted P < 0.05 using the predefined hypothesis-testing hierarchy). Patients who switched from placebo to secukinumab at week 16 showed rapid improvements in ACR50 rates; by week 52, both treatment arms experienced similar improvements in efficacy outcomes. No new or unexpected safety signals were observed with receiving IV secukinumab. One death was reported in the placebo group before week 16. CONCLUSION: IV secukinumab led to rapid and sustained improvements in clinical measures of PsA, and the safety profile was consistent with that of secukinumab administered subcutaneously.

BACKGROUND: Recently, a plethora of novel systemic agents have been incorporated into the therapeutic armamentarium of advanced urothelial carcinoma (aUC). The antibody-drug conjugate (ADC), enfortumab vedotin (EV), has demonstrated relevant clinical benefit in patients with aUC refractory to platinum and immune-checkpoint inhibitor (ICI) therapy. Our study provides a retrospective, international, real-world analysis comparing the effectiveness of EV to chemotherapy in this setting. METHODS: The data were extracted from the medical records of patients treated with EV or chemotherapy following pembrolizumab for recurrent or progressive aUC after platinum-based chemotherapy. Patients were assessed for overall survival (OS), progression-free survival (PFS), overall response rate (ORR) and duration of response (DoR). RESULTS: Our analysis included 247 patients treated with EV (88, 36%) or chemotherapy (159, 64%). Median OS was 9.1 months (95%CI 7.2-10.7) in the overall study population, 13.6 months (95%CI 10.0-31.0) in patients receiving EV and 6.8 months (95%CI 6.0-8.9) in patients receiving chemotherapy (p < 0.001). The OS benefit of EV was not affected by primary tumour site and histology, metastatic sites, type of first platinum-based chemotherapy or response to pembrolizumab. In the EV cohort, the median PFS was significantly longer (8.8 months [95%CI 6.5-17.0] vs. 3.0 months [95%CI 2.6-3.7]) and the ORR was significantly higher (56% vs. 23%) than in the chemotherapy cohort. CONCLUSIONS: The results of our international analysis of real-world data confirm the effectiveness of EV in the sequential strategy of aUC patients who have received prior platinum-based chemotherapy and anti-PD-1 pembrolizumab, regardless of commonly considered prognostic factors.

INTRODUCTION: Currently, limited data are available on long-term use of dupilumab to treat atopic dermatitis (AD) in a multinational real-world setting. The aim of this analysis was to report the interim 1-year data for patients with AD enrolled in the GLOBOSTAD registry, including treatment patterns, dupilumab effectiveness and safety, and healthcare burden. METHODS: GLOBOSTAD is an ongoing, 5-year, multinational, prospective, observational study of adult/adolescent (aged ≥ 12 years at baseline) patients with AD who initiated dupilumab in real-world settings according to their local country-specific prescribing guidelines. Outcomes were evaluated at baseline and at 3, 6 and 12 months and included Eczema Area and Severity Index (EASI) total score, SCORing Atopic Dermatitis (SCORAD) total score, percent body surface area (BSA) affected, Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI) total score for adults or Children's Dermatology Life Quality Index (CDLQI) total score for adolescents and pruritus Numeric Rating Scale (NRS) total score. RESULTS: At the interim 1-year cut-off (March 2023), 955 patients were enrolled in GLOBOSTAD, and follow-up data were obtained from 903 patients. After dupilumab initiation, mean improvements in effectiveness outcome measures from baseline to month 3 were EASI from 25.1 to 6.1, SCORAD 59.3 to 25.3, POEM 19.7 to 8.7, DLQI 13.7 to 5.3, CDLQI 12.2 to 2.7 and pruritus NRS 6.3 to 2.5, with each measure exceeding the minimal clinically important difference. These positive changes in effectiveness outcomes were maintained or further improved through 12 months since treatment initiation. AD-related hospitalizations and emergency room or urgent care facility visits decreased from 11.1% to 1.7% from baseline to month 12. CONCLUSIONS: In a multinational real-world setting, dupilumab demonstrated rapid, robust and sustained effectiveness in patients with moderate-to-severe AD across multiple disease domains, including AD signs, symptoms, quality of life and emergency/urgent care visits. Safety was consistent with the known dupilumab safety profile. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03992417.

Atopic dermatitis (AD) is a chronic relapsing skin disease that can have a negative effect on the quality of patients’ lives. In clinical trials, when patients with AD were treated with a drug called dupilumab, there were improvements in their AD signs and symptoms and quality of life. More information is needed about how well dupilumab works when patients are prescribed the drug by their doctors in the real world over a long period. In total, almost 1000 adults and adolescents with AD joined a prospective observational study called GLOBOSTAD. GLOBOSTAD aims to follow them for up to 5 years after their first dupilumab treatment. This study looked at the effects of dupilumab in about 900 patients during their first year of treatment. At 3 months after starting dupilumab, there were improvements in each of the measures that show how effective a treatment is. These included measures that doctors use to judge how serious AD is. They also included measures that patients use to report how serious they feel their AD is and how AD affects their quality of life. After 1 year, those changes had either stayed or improved further. After 1 year, there was also an improvement in how often patients had to visit the hospital because of their AD. Safety was consistent with the known dupilumab safety information.

OBJECTIVE: Our goal was to assess the efficacy and safety of intravenous (IV) secukinumab for the treatment of adults with active axial spondyloarthritis (axSpA) in INVIGORATE-1. METHODS: INVIGORATE-1 (NCT04156620) was a randomized, double-blind, parallel-group, phase 3 trial in patients with active axSpA (either radiographic or nonradiographic). Patients were randomized one to one to receive IV secukinumab (6 mg/kg at baseline followed by 3 mg/kg every four weeks) or IV placebo for 16 weeks. After week 16, patients randomized to placebo were switched to IV secukinumab (3 mg/kg every four weeks), and patients randomized to secukinumab continued treatment through week 52. The primary endpoint was the Assessment of SpondyloArthritis International Society (ASAS40) response at week 16. Safety was evaluated through week 60. RESULTS: Among patients initially randomized to IV secukinumab (n = 264) or placebo (n = 262), 86.0% and 88.9% completed the entire 60-week study period, respectively. A higher proportion of patients receiving secukinumab versus placebo met the primary endpoint (ASAS40 response) at week 16 (40.9% vs 22.9%; P < 0.0001). By week 24, patients who switched from placebo to secukinumab at week 16 achieved ASAS40 response rates comparable to those in patients originally randomized to secukinumab. All secondary efficacy endpoints were met at week 16, and responses were sustained through week 52. No new or unexpected safety signals were observed with IV secukinumab. CONCLUSION: IV secukinumab was effective for the treatment of adults with active axSpA over 52 weeks. The safety profile was consistent with that in previous reports on subcutaneous secukinumab.

BACKGROUND: Given burdensome side-effects and long latency for efficacy with conventional agents, there is a continued need for generalised myasthenia gravis treatments that are safe and provide consistently sustained, long-term disease control. Nipocalimab, a neonatal Fc receptor blocker, was associated with dose-dependent reductions in total IgG and anti-acetylcholine receptor (AChR) antibodies and clinically meaningful improvements in the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale in patients with generalised myasthenia gravis in a phase 2 study. We aimed to assess the safety and efficacy of nipocalimab in a phase 3 study. METHODS: Vivacity-MG3 was a phase 3, randomised, double-blind, placebo-controlled, phase 3 study conducted at 81 outpatient centres with expertise in myasthenia gravis in 17 countries in Asia-Pacific, Europe, and North America. Adults (aged ≥18 years) with generalised myasthenia gravis inadequately controlled with standard-of-care therapy (MG-ADL score ≥6) were randomly assigned (1:1) to either nipocalimab (30 mg/kg loading dose then 15 mg/kg every 2 weeks for maintenance dosing) or placebo infusions every 2 weeks, added to standard-of-care therapy in both groups, for 24 weeks. Randomisation was stratified by antibody status, day 1 MG-ADL total score, and region. The sponsor, investigators, clinical raters, and participants were masked to treatment assignment. The primary endpoint was the difference between nipocalimab and placebo based on least-squares mean change from baseline in MG-ADL total score averaged over weeks 22, 23, and 24 in the intention-to-treat population of patients who were antibody-positive (for AChR, anti-muscle-specific tyrosine kinase [MuSK], or anti-low-density lipoprotein receptor-related protein 4 [LRP4]). Adverse events were assessed in patients who received at least one dose of study drug. This study is registered at ClinicalTrials.gov, NCT04951622; the double-blind phase is completed and an open-label extension phase is ongoing. FINDINGS: Between July 15, 2021, and Nov 17, 2023, 199 patients were enrolled, and 196 patients received study drug (98 in the nipocalimab group and 98 in the placebo group); of these, 153 (77 in the nipocalimab group and 76 in the placebo group) were antibody-positive. The least-squares mean change in MG-ADL score from baseline to weeks 22, 23, and 24 was -4·70 (SE 0·329) in the nipocalimab group versus -3·25 (0·335) in the placebo group (difference -1·45 [95% CI -2·38 to -0·52]; p=0·0024). The incidence of adverse events was similar between groups (82 [84%] of 98 in both the nipocalimab and placebo groups), including infections (42 [43%] of 98 in the nipocalimab group and placebo group) and headache (14 [14%] of 98 in the nipocalimab group and 17 [17%] of 98 in the placebo group). Serious adverse events were reported for nine (9%) of 98 patients in the nipocalimab group and 14 (14%) of 98 patients in the placebo group, three of which had a fatal outcome (nipocalimab: myasthenic crisis; placebo: cardiac arrest and myocardial infarction). INTERPRETATION: Results from the completed double-blind phase of Vivacity-MG3 support the role of nipocalimab, added to standard-of-care therapies, as a safe treatment for sustained disease control over 6 months for a broad population of patients with generalised myasthenia gravis who are antibody-positive. The ongoing open-label extension phase should provide longer term sustained safety and efficacy data with nipocalimab. FUNDING: Janssen Research & Development, LLC, a Johnson & Johnson company.
