A 24-week multicentre, randomized, open-label, parallel-group study comparing the efficacy and safety of ixekizumab vs. fumaric acid esters and methotrexate in patients with moderate-to-severe plaque psoriasis naive to systemic treatment.

ABSTRACT: BACKGROUND:Interleukin-17 antagonists have received a first-line label for moderate-to-severe plaque psoriasis. OBJECTIVES:We conducted the first head-to-head trial between the two most commonly used first-line therapies in Germany, fumaric acid esters (FAEs) and methotrexate, and the interleukin-17A antagonist, ixekizumab. METHODS:Systemic-naive patients were randomized in this parallel-group, active-comparator, open-label, rater-blinded trial (each group n = 54). The primary outcome was the proportion of patients achieving ? 75% improvement in Psoriasis Area and Severity Index (PASI 75) at 24 weeks. Key secondary outcomes included 24-week PASI 90 and 100, static Physician's Global Assessment (sPGA) score of 0 or 1, and Dermatology Life Quality Index (DLQI) score of 0 or 1. Safety events at week 24 were analysed using Fisher's exact test. Missing data were imputed using nonresponder imputation. The trial was registered at ClinicalTrials.gov (NCT02634801) and EudraCT (2015-002649-69). RESULTS:At week 24, more ixekizumab-treated patients achieved PASI 75 [91% vs. 22% FAEs (P < 0·001) and 70% methotrexate (P = 0·014)], PASI 90 [80% vs. 9% FAEs (P < 0·001) and 39% methotrexate (P < 0·001)] and PASI 100 [41% vs. 4% FAEs (P < 0·001) and 13% methotrexate (P = 0·0041)], as well as sPGA (0,1) and DLQI (0,1). CONCLUSIONS:Ixekizumab was superior in inducing PASI 75/90/100, sPGA (0,1) and DLQI (0,1) responses at week 24 compared with methotrexate and FAEs. Safety profiles for all treatments were consistent with prior studies.

Project description:BackgroundPlaque psoriasis has significant impact on patients' quality of life. Topical therapy is considered the treatment mainstay for mild-to-moderate disease according to guidelines. Calcipotriol/betamethasone dipropionate (Cal/BD) [0.005%/0.05%] aerosol foam is indicated for psoriasis vulgaris treatment in adults. Cal/BD foam trials demonstrated improved efficacy and similar safety in this population. Psoriasis treatment is complicated by the broad range of disease presentation, variability and therapeutic options; particularly decisions on transition from topical to non-biologic systemic treatment are difficult. Assessing comparative effectiveness of treatment options provides meaningful value to treatment decisions.ObjectiveTo compare efficacy of Cal/BD foam individual patient data from pooled trials with efficacy of non-biologic systemic treatments based on aggregated patient characteristics and treatment outcomes.MethodsIndividual data from four Cal/BD foam trials in 749 psoriasis patients were pooled to conduct matching-adjusted indirect comparisons. Literature review identified non-biologic systemic treatment trials where methods, populations and outcomes align with Cal/BD foam trials. Of 3090 screened publications, four studies of apremilast, methotrexate, acitretin or fumaric acid esters (FAE) were included.ResultsAfter baseline matching, patients treated with 4 weeks of Cal/BD foam had greater Physician's Global Assessment 0/1 response compared to those treated with 16 weeks of apremilast (52.7% vs. 30.4%; P < 0.001). Patients treated with Cal/BD foam had significantly greater Psoriasis Area and Severity Index (PASI) 75 response at Week 4 compared to 16 weeks of apremilast treatment (51.1% vs. 21.6%; P < 0.001). Cal/BD foam patients demonstrated significantly greater PASI 75 response improvements at Week 4 vs. 12 weeks of methotrexate (50.8% vs. 33.5%; P < 0.001) or acitretin (50.9% vs. 31.7%; P = 0.009), and comparable response to FAE (42.4% vs. 47.0%; P = 0.451).ConclusionsDespite recent treatment advances, unmet needs for psoriasis patients remain. Cal/BD foam offers improved efficacy in baseline matched psoriasis patients compared to apremilast, methotrexate or acitretin, and comparable efficacy to FAE.

Project description:BackgroundSignificantly more patients with moderate-to-severe plaque psoriasis treated with the interleukin (IL)-17A inhibitor ixekizumab vs. the IL-23p19 inhibitor guselkumab in the IXORA-R head-to-head trial achieved 100% improvement in Psoriasis Area and Severity Index (PASI 100) at week 12.ObjectivesTo compare skin and nail clearance and patient-reported outcomes for ixekizumab vs. guselkumab, up to week 24.MethodsIXORA-R enrolled adults with moderate-to-severe plaque psoriasis, defined as static Physician's Global Assessment ≥ 3, PASI ≥ 12 and involved body surface area ≥ 10%. Statistical comparisons were performed using the Cochran-Mantel-Haenszel test stratified by pooled site. Time-to-first-event comparisons were performed using Kaplan-Meier analysis, and P-values were generated using adjusted log-rank tests stratified by treatment group. Cumulative days at clinical and patient-reported responses were compared by ancova. The trial was registered with ClinicalTrials.gov (NCT03573323).ResultsOf the 1027 patients randomly assigned, 90% completed the trial (465 of 520 ixekizumab and 459 of 507 guselkumab). As early as week 2 and through week 16, more patients on ixekizumab achieved PASI 100 (P < 0·01). At week 24, ixekizumab was noninferior to guselkumab (50% vs. 52%, difference -2·3%), with no statistically significant difference in PASI 100 (P = 0·41). More patients receiving ixekizumab showed completely clear nails at week 24 (52% vs. 31%, P = 0·007). The median time to first PASI 50/75/90 and PASI 100 were 2 and 7·5 weeks shorter, respectively, for patients on ixekizumab vs. guselkumab (P < 0·001). Patients on ixekizumab also had a greater cumulative benefit, with more days at PASI 90 and 100, with Dermatology Life Quality Index of 0 or 1, and itch free (P < 0·05). The frequency of serious adverse events was 3% for each group, with no new safety signals.ConclusionsIxekizumab was noninferior to guselkumab in complete skin clearance and superior in clearing nails at week 24. Ixekizumab cleared skin more rapidly in patients with moderate-to-severe plaque psoriasis, with a greater cumulative benefit, than guselkumab. Overall, the safety findings were consistent with the known safety profile for ixekizumab.

Project description:IntroductionIn the SPIRIT-H2H (ClinicalTrials.gov: NCT03151551) trial in biologic-naïve patients with active psoriatic arthritis (PsA), ixekizumab (IXE) was superior to adalimumab (ADA) at week 24 in terms of achieving a combined endpoint of ≥ 50% improved response in the American College of Rheumatology scale score (ACR50) and 100% improvement in the Psoriasis Areas and Severity Index (PASI100), and was non-inferior in terms of achieving ACR50. IXE resulted in similar improvements of PsA manifestations irrespective of the use of concomitant conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), while ADA response was higher with concomitant csDMARD use. The aim of this study was to determine the efficacy and safety of treatment with IXE and ADA with or without methotrexate (MTX), the most commonly use csDMARD, through week 52 in patients with PsA.MethodsIn the open-label, rater-blinded, head-to-head SPIRIT-H2H trial, randomization of patients was stratified by concomitant use of csDMARD and moderate-to-severe plaque psoriasis involvement. In the post-hoc subgroup analysis presented here, subgroups were defined as with/without concomitant MTX use at baseline. Treatment group effects within subgroups were tested using Fisher's exact test. Missing data were imputed using non-responder imputation.ResultsBy week 52, IXE provided similar improvements in the combined ACR50 and PASI100 endpoint, ACR50, and other PsA-related domains regardless of whether IXE was used with or without MTX, while ADA efficacy appeared to be improved with concomitant MTX use. When used without concomitant MTX, IXE resulted in significantly higher response versus ADA in terms of the combined ACR50 and PASI100 (p = 0.002) endpoint, minimal disease activity (p = 0.016), and very low disease activity (p = 0.037). The safety of both agents was consistent with their known safety profiles regardless of concomitant MTX use.ConclusionIn PsA patients with inadequate control of the disease, IXE delivers consistent efficacy in several clinical domains of the disease regardless of concomitant MTX use. The efficacy of ADA is increased by the concomitant use of MTX. These findings can inform treatment decisions when considering the need for concomitant MTX use with IXE or ADA at initiation or for long-term maintenance.
