Matching-adjusted indirect comparisons (MAICs) were used to compare the efficacy of bimekizumab and secukinumab 150 mg and 300 mg at 52 weeks for the treatment of psoriatic arthritis (PsA) in patients who were biologic disease-modifying anti-rheumatic drug-naïve (bDMARD-naïve) or with previous inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi-IR).
Methods
Relevant trials were systematically identified. Individual patient data from bimekizumab randomized controlled trials, BE OPTIMAL (N = 431) and BE COMPLETE (N = 267), were matched to aggregate data from bDMARD-naïve and TNFi-IR patient subgroups from FUTURE 2 using secukinumab 150 mg and 300 mg doses (bDMARD-naïve: N = 63/37; TNFi-IR: N = 67/33). To adjust for cross-trial differences, patients from the bimekizumab trials were re-weighted using propensity scores to match the baseline characteristics of patients in the secukinumab trials. Unanchored comparisons of recalculated bimekizumab and secukinumab 52-week non-responder imputation outcomes for 20/50/70% improvement in American College of Rheumatology score (ACR20/50/70) and minimal disease activity (MDA) index were analyzed.
Results
In patients who were bDMARD-naïve, bimekizumab had a greater likelihood of ACR70 response than secukinumab 150 mg (odds ratio [95% confidence interval] 2.39 [1.26, 4.53]; p = 0.008) and secukinumab 300 mg (2.03 [1.11, 3.72]; p = 0.021) at 52 weeks. In patients who were TNFi-IR, bimekizumab had a greater likelihood of response compared to secukinumab 150 mg for ACR20 (3.50 [1.64–7.49]; p = 0.001), ACR50 (3.32 [1.41, 7.80]; p = 0.006), ACR70 (2.95 [1.08, 8.07]; p = 0.035) and MDA (3.52 [1.38, 8.99]; p = 0.009), and a greater likelihood of response compared to secukinumab 300 mg for ACR50 (2.44 [1.06, 5.65]; p = 0.037) and MDA (2.92 [1.20, 7.09]; p = 0.018) at 52 weeks.
Conclusion
In this MAIC analysis, the efficacy of bimekizumab, as demonstrated by the likelihood of ACR20/50/70 and MDA response at 52 weeks, was greater or comparable to secukinumab 150 mg and 300 mg for patients with PsA who were bDMARD-naïve and TNFi-IR.

Key Summary Points
Why carry out this study?
There is currently no direct head-to-head evidence of the long-term efficacy of bimekizumab compared to other interleukin (IL)-17A inhibitors in psoriatic arthritis (PsA)
This study uses matching-adjusted indirect comparisons (MAICs) to compare the efficacy of bimekizumab 160 mg every 4 weeks (Q4W) and secukinumab 150 mg and 300 mg Q4W at 52 weeks for the treatment of PsA in patients who were naïve to biologic disease-modifying anti-rheumatic drugs (bDMARD-naïve) or patients who have previous inadequate response or intolerance to tumor necrosis factor (TNF) inhibitors (TNFi-IR)
What was learned from this study?
In patients who were bDMARD-naïve, bimekizumab had a greater likelihood of achieving at least a 70% improvement according to American College of Rheumatology response criteria (ACR70) outcome compared to secukinumab 150 mg and secukinumab 300 mg at 52 weeks
In patients who were TNFi-IR, bimekizumab had a greater likelihood of response compared to secukinumab 150 mg for ACR20, ACR70, and minimal disease activity (MDA) outcomes and a greater likelihood of response compared to secukinumab 300 mg for ACR50 and MDA outcomes at 52 weeks
Bimekizumab can be considered as more effective than, or at least comparable to, secukinumab in achieving long-term, positive treatment outcomes in PsA
Introduction
Psoriatic arthritis (PsA) is a chronic, systemic disease characterized by musculoskeletal inflammation affecting up to a third of patients with psoriasis [1]. A range of biologic and targeted synthetic biological disease-modifying anti-rheumatic drugs (b/tsDMARDs) are now available for the treatment of PsA and have brought about significant clinical improvements in outcomes.

Recent focus has fallen upon the wider utility of the interleukin (IL)-17 cytokine superfamily in terms of therapeutic targeting to deliver increased efficacy in PsA, especially in treatment-resistant disease [2]. The IL-17 family includes IL-17A and IL-17F, both of which possess pro-inflammatory properties that could potentially offer synergistic therapeutic value as targets. The efficacy of IL-17A inhibition by secukinumab and ixekizumab in PsA has previously been established [2] and the FUTURE phase 3 program dataset for randomized controlled trials (RCTs) of secukinumab in the treatment of PsA has previously been published [3‐7]. Bimekizumab is a humanized monoclonal immunoglobulin G1 antibody that selectively inhibits IL-17A, in addition to IL-17F, and has recently been approved in Europe for PsA. Its efficacy and safety were established in two phase 3 RCTs: BE OPTIMAL (NCT03895203) [8] in patients who were naïve to biologic disease-modifying anti-rheumatic drugs (bDMARD-naïve), and BE COMPLETE (NCT03896581) [9] in patients who had previous inadequate response or intolerance to tumor necrosis factor (TNF) inhibitors (TNFi-IR). An open-label extension (OLE) of both trials, BE VITAL (NCT04009499) [10], is also currently ongoing to assess the long-term efficacy. Bimekizumab was superior to secukinumab in plaque psoriasis in the BE RADIANT RCT (NCT03536884) [11], but as yet, there is no direct head-to-head evidence of the long-term efficacy of bimekizumab compared to other IL-17A mono-inhibitors in PsA.
When head-to-head comparisons in RCTs are unavailable, matching-adjusted indirect comparisons (MAICs) can be used to overcome limitations in assessing comparative efficacy due to insufficiently reported data (e.g., unavailable long-term placebo data in PsA) [12, 13]. A MAIC uses propensity score matching techniques to re-weight individual patient data (IPD) from one study on the basis of the summary baseline characteristics from another, enabling adjustment of differences between trials and allowing comparison between observed treatments [14]. In PsA, MAIC techniques have previously been used to compare the efficacy of secukinumab with other bDMARDs (vs adalimumab [15] and infliximab [16]). Secukinumab was therefore selected as a well-established IL-17A inhibitor for comparison to bimekizumab.
In this study, MAICs were conducted to assess the relative efficacy of bimekizumab versus secukinumab (150 mg or 300 mg doses) at 52 weeks in patients with PsA who were bDMARD-naïve or TNFi-IR. This MAIC analysis aims to provide additional long-term comparative data of bimekizumab and secukinumab following the findings of the recent network meta-analysis (NMA) up to week 24 [17].
Methods
Systematic Literature Review and Source Data
A systematic literature review (SLR) was conducted according to the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines [18] to identify relevant clinical evidence for existing bDMARD therapies in PsA published from January 1991 to December 2022. Details on SLR eligibility criteria and reasons for inclusion/exclusion were previously published [17]. This MAIC focuses on the comparison with secukinumab because of its high real-world utilization in PsA [19]. The FUTURE 2 RCT (NCT01752634) [4] for secukinumab was identified as most relevant for this MAIC analysis as it was the pivotal trial used for regulatory and Health Technology Assessment in Europe [20]. In this analysis, the efficacy of bimekizumab dosed at 160 mg every 4 weeks (Q4W) was compared to secukinumab at two dose levels, 150 mg and 300 mg Q4W. Although both secukinumab doses are common in clinical practice, the European Medicines Agency guidance recommends that the 300 mg dose be given to patients with PsA who were TNFi-IR [19‐21]. Pooled data from all relevant secukinumab RCTs (FUTURE 2, FUTURE 3 [NCT01989468], FUTURE 4 [NCT02294227], and FUTURE 5 [NCT02404350]) were used for a sensitivity analysis comparison [22]. Ethical approval was obtained from the relevant institutional review boards at participating sites, and all patients provided written informed consent in accordance with local requirements. BE OPTIMAL and BE COMPLETE were conducted in accordance with Declaration of Helsinki and the International Conference on Harmonisation Guidance for Good Clinical Practice.

Selection of Baseline Characteristics for Matching
Adjustment variables were selected on the basis of a review of previous MAICs in PsA [15, 16], consensus agreement with clinical experts (n = 5), and adherence to established MAIC guidelines [14]. Exploratory univariate sensitivity analyses evaluated the impact of all adjustment variables. To adjust for cross-trial differences, patients from the bimekizumab trials were re-weighted to match the baseline characteristics of the patients in FUTURE 2. Weights were determined on the basis of age, sex, methotrexate (MTX) use, Health Assessment Questionnaire Disability Index (HAQ-DI) score, percentage with psoriasis affecting ≥ 3% body surface area (BSA ≥ 3%), swollen joint count—68 joints (SJC 68), tender joint count—66 joints (TJC 66). Adjustments for race, weight, and DMARD use at baseline were excluded as they were well balanced across trials and their adjustment impact was minimal. Adjustments for dactylitis and enthesitis at baseline were excluded as the impact of the effective sample size (ESS) was assessed to be too large, leading to an unbalanced distribution of weights. For the FUTURE 2 trial, baseline characteristics were assumed to be similar for between patients randomized to secukinumab 150 mg and secukinumab 300 mg for the same study population (either bDMARD-naïve or TNFi-IR).
Adjustment of IPD to Aggregate Data and Pairwise Comparisons
The MAIC methodology as previously described by Signorovitch et al. [14] and the National Institute for Health and Care Excellence Decision Support Unit Technical Support Document 18 (NICE DSU TSD 18) was followed to create a robust population-adjusted indirect treatment comparison (ITC) [13]. All analyses were conducted with R version 3.6.2. The R program provided by the NICE DSU TSD 18 was used to implement this MAIC.
For the base case analysis in patients who were bDMARD-naïve, IPD from BE OPTIMAL was matched to summary patient data from a subgroup of bDMARD-naïve patients in FUTURE 2 for pairwise comparisons. For patients who were TNFi-IR, IPD from the bimekizumab arm of BE COMPLETE/BE VITAL and summary data from a subgroup of patients who were TNFi-IR in FUTURE 2 were used for pairwise comparisons (Fig. 1).

In the sensitivity analysis, IPD from BE OPTIMAL and BE COMPLETE/BE VITAL were matched to pooled patient data from FUTURE 2, 3, 4, and 5 RCTs in bDMARD-naïve and TNFi-IR patient subgroups separately, for pairwise comparisons.
Outcomes
The outcomes reported were the proportion of patients with 20/50/70% improvement in the American College of Rheumatology criteria (ACR20/50/70) and minimal disease activity (MDA, minimum 5 out of 7 domains achieved) scores. These were selected in line with the Outcomes Measures in Rheumatology (OMERACT) and the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) guidelines [23, 24]. For this MAIC analysis, week 52 data from both bimekizumab and secukinumab RCTs were used to compare outcomes as it was the longest time point at which efficacy data were available for both treatments at the time of the analysis.
Analyses of Psoriasis Area and Severity Index (PASI) scores, enthesitis resolution, dactylitis resolution, and inhibition of radiographic progression outcomes were not feasible as the baseline characteristics of the respective patient subsets were not sufficiently reported in their respective RCTs.
Reporting of Missing Data
Published outcomes included in this MAIC analysis were taken from the intent-to-treat population in all relevant trials (FUTURE 2, BE OPTIMAL, BE COMPLETE, and BE VITAL). Missing binary outcome data (ACR20/50/70 and MDA) were handled using non-responder imputation (NRI) methods.
Non-Placebo-Adjusted Outcome Comparisons
All patients randomized to placebo in the bimekizumab and secukinumab RCTs received active treatment from week 16 to 24 onwards, resulting in the absence of placebo as a common comparator in all RCTs after week 24. Non-placebo-adjusted (unanchored) outcomes at week 52 from the secukinumab 150 mg and 300 mg pooled arms of FUTURE 2 were directly compared with recalculated outcomes from the bimekizumab arms in BE OPTIMAL and BE COMPLETE/BE VITAL.

Reporting of Results
After matching, the ESS indicates the number of independent, non-weighted individuals required to give an estimate with the same precision as the weighted sample estimate and is expressed as a proportion of the original sample size (OSS) from the source trials. Recalculated outcomes were reported as adjusted response rates and the relative effects of bimekizumab versus secukinumab in different patient groups were reported as odds ratios (ORs) with 95% confidence intervals (95% CI, based on ESS). A standard value of p ≤ 0.05 was considered as the threshold for concluding statistical significance (i.e., greater/lesser likelihood or comparable at achieving an outcome response compared to secukinumab).
Results
Patient baseline values for adjusted characteristics prior to matching are provided in Table 1 for both bDMARD-naïve and TNFi-IR patient subgroups in the bimekizumab and secukinumab RCTs. Prior to matching, a greater proportion of patients in the BE OPTIMAL and BE COMPLETE/BE VITAL trials had psoriasis covering BSA ≥ 3% (TNFi-IR patients only in BE COMPLETE/BE VITAL), were receiving MTX therapy, had lower HAQ-DI scores, and had lower SJC/TJC scores compared to patients in the corresponding subgroups in FUTURE 2.

In this MAIC analysis, patients from the bimekizumab arm of BE OPTIMAL (n = 431) were matched to a subgroup of patients who were bDMARD-naïve from FUTURE 2 (secukinumab 150 mg, n = 63; secukinumab 300 mg, n = 67). After matching, the post-matching ESS for bimekizumab was 236.15 (54.8% of the OSS) for comparison to both secukinumab 150 mg and 300 mg Q4W (Fig. 2a/c and Table S1).

In patients who were bDMARD-naïve, bimekizumab had a greater likelihood of achieving ACR70 response than secukinumab 150 mg at week 52 (OR [95% CI] 2.39 [1.26, 4.53], p = 0.008) and was comparable with secukinumab 150 mg in achieving ACR20 (0.64 [0.32, 1.26], p = 0.193), ACR50 (1.20 [0.69, 2.10], p = 0.522), and MDA (1.77 [1.00, 3.15], p = 0.051) responses (Fig. 2a). Compared to secukinumab 300 mg, bimekizumab had a greater likelihood of achieving ACR70 (2.03 [1.11, 3.72], p = 0.021) response at week 52 and was comparable in achieving ACR20 (1.12 [0.62, 2.03], p = 0.704), ACR50 (1.06 [0.62, 1.83], p = 0.827), and MDA (1.53 [0.87, 2.68], p = 0.138) responses (Fig. 2c).
TNFi-IR Patient Subgroup
Patients from the bimekizumab arm of BE COMPLETE (n = 267) were matched to a subgroup of patients who were TNFi-IR from FUTURE 2 (secukinumab 150 mg, n = 37; secukinumab 300 mg, n = 33). The post-matching ESS for bimekizumab was 145.50 (54.5% of OSS) for comparison to both secukinumab 150 mg and 300 mg Q4W (Fig. 2b/d and Table S2).
In patients who were TNFi-IR, bimekizumab had a greater likelihood of response for all ACR and MDA outcomes than secukinumab 150 mg at week 52 (ACR20: 3.50 [1.64, 7.49], p = 0.001; ACR50: 3.32 [1.41, 7.80], p = 0.006; ACR70: 2.95 [1.08, 8.07], p = 0.035; MDA: 3.52 [1.38, 8.99], p = 0.009) (Fig. 2b). Compared to secukinumab 300 mg, bimekizumab had a greater likelihood of achieving ACR50 (2.44 [1.06, 5.65]; p = 0.037) and MDA (2.92 [1.20, 7.09], p = 0.018) responses at week 52 and was comparable in achieving ACR20 (1.78 [0.82, 3.87], p = 0.147) and ACR70 (2.08 [0.80, 5.37], p = 0.131) responses (Fig. 2d).

In patients who were bDMARD-naïve, bimekizumab had a greater likelihood of achieving ACR50 response than secukinumab 150 mg at week 52 (1.46 [1.11, 1.93], p = 0.007) and was comparable with secukinumab 150 mg in achieving ACR20 response (1.17 [0.87, 1.59], p = 0.305) (Fig. 3a). Bimekizumab was also comparable with secukinumab 300 mg in achieving ACR20 (1.02 [0.71, 1.45], p = 0.926) and ACR50 (1.19 [0.86, 1.65], p = 0.283) responses at week 52 (Fig. 3c).
TNFi-IR Patient Subgroup
Patients in the bimekizumab arm of BE COMPLETE (n = 267) were matched to a subgroup of patients who were TNFi-IR from pooled analyses of FUTURE 2–5 (secukinumab 150 mg, n = 264; secukinumab 300 mg, n = 145). The post-matching ESSs for bimekizumab were 116.71 (43.7% of OSS) and 141.99 (53.2% of OSS) for the comparison to secukinumab 150 mg and 300 mg Q4W, respectively (Fig. 3b/d and Table S4).
In patients who were TNFi-IR, bimekizumab had a greater likelihood of achieving ACR20 (2.52 [1.57, 4.03], p < 0.001) and ACR50 (2.72 [1.71, 4.32], p < 0.001) response than secukinumab 150 mg at week 52 (Fig. 3c). Bimekizumab also had a greater likelihood of achieving ACR20 (1.69 [1.04, 2.76], p = 0.034) and ACR50 (2.16 [1.32, 3.53], p = 0.002) responses than secukinumab 300 mg at week 52 (Fig. 3d).
Unadjusted and adjusted response rates and ORs for both the base case and sensitivity analyses are available from Tables S1 to S4 in the Supplementary Materials. The adjusted ORs were comparable to the unadjusted ORs for all outcomes, which provides further support for the validity of these findings.
Discussion
This study used a MAIC analysis to assess the comparative efficacy of bimekizumab 160 mg Q4W against secukinumab 150 mg or 300 mg Q4W at 52 weeks. Patients receiving bimekizumab who were bDMARD-naïve had a higher probability of achieving ACR70 response at 52 weeks compared to patients receiving secukinumab 150 mg and 300 mg doses. Bimekizumab was statistically comparable but numerically better than secukinumab 150 mg and 300 mg for all other measured outcomes (except ACR20) in bDMARD-naïve patients.
Anzeige
Patients treated with bimekizumab who were TNFi-IR had a higher probability of achieving any ACR response compared to those receiving secukinumab 150 mg, and a higher probability of achieving ACR50/MDA response compared to those receiving secukinumab 300 mg at 52 weeks. Bimekizumab was statistically comparable but numerically better than secukinumab 150 mg and 300 mg for all other measured outcomes in patients who were TNFi-IR. A sensitivity analysis using pooled data from FUTURE 2–5 RCTs corroborated the favorable efficacy of bimekizumab over secukinumab for ACR20 and ACR50 outcomes. These findings are also consistent with a recently published NMA in which bimekizumab ranked higher in efficacy than secukinumab on most joint outcomes at 16 to 24 weeks [17].
In PsA, IL-17A and IL-17F are considered key pro-inflammatory mediators. Their biological roles in PsA are, however, not identical and each appears to offer both overlapping and distinctive effector functions in the type 17 immune response in human systems, with the latter being considered pivotal in PsA pathogenesis [25]. The ability of a potential treatment to inhibit both IL-17A and IL-17F can provide patients with a greater inhibition of inflammation. The dual specificity of the bimekizumab antigen for IL-17A and IL-17F allows optimal binding of either isoform and prevent pro-inflammatory signaling regardless of the proportions in which the cytokines are present [26].
Study Limitations
This MAIC analysis has limitations, both intrinsic to the methodology and specific to this analysis. This MAIC analysis required the use of patient-level data of patients who were TNFi-IR from the BE VITAL OLE trial. The efficacy analyses used for BE VITAL were conducted by NRI using the total patient population that started BE COMPLETE, thereby reducing uncertainties introduced from using OLE data. All patients completing week 16 in BE COMPLETE were eligible to enroll in BE VITAL and patients receiving placebo were switched to bimekizumab. Although observed patient variables at baseline could be matched, it was not possible to control unobserved or unreported variables. There were also differences in the duration of the placebo-controlled segment between RCTs (range 16 weeks for BE OPTIMAL/BE COMPLETE to 24 weeks for FUTURE 2). For the FUTURE 2 trial, baseline characteristics had to be assumed to be similar between patients randomized to secukinumab 150 mg and secukinumab 300 mg for the same study population (either bDMARD-naïve or TNFi-IR) as patient baseline data were not stratified by different dosages. There was variation in the study designs at week 52 (dose blind [FUTURE 2–5] vs active treatment blind [BE OPTIMAL] vs open-label [BE COMPLETE/BE VITAL]), although none of the studies were placebo-controlled at that stage, meaning all patients included in this MAIC were aware that they were receiving active treatment until week 52. Analyses of PASI scores, enthesitis resolution, dactylitis resolution, and inhibition of radiographic progression were not feasible as outcomes assessed in the RCT were only based on a subset of the trial population for which baseline characteristics were not sufficiently reported. Safety outcomes could not be analyzed as the original secukinumab trial (FUTURE 2) did not provide safety data stratified by subgroups of interest (bDMARD-naïve or TNFi-IR).
Conclusion
On the basis of MAIC analysis, bimekizumab demonstrated favorable efficacy for the ACR70 outcome compared to secukinumab 150 mg and 300 mg in patients with PsA who were bDMARD-naïve. In patients with PsA who were TNFi-IR, bimekizumab demonstrated a favorable efficacy for all measured outcomes compared to secukinumab 150 mg, and for ACR50 and MDA outcomes compared to secukinumab 300 mg. The results of this analysis should be viewed in the context of the limitations for an indirect comparison, yet the use of IPD and established MAIC methodology provides comparative evidence in the absence of a confirmatory head-to-head RCT.

Ob bei einer Notfalloperation nach Schenkelhalsfraktur eine Hemiarthroplastik oder eine totale Endoprothese (TEP) eingebaut wird, sollte nicht allein vom Alter der Patientinnen und Patienten abhängen. Auch über 90-Jährige können von der TEP profitieren.
Wenn unter einer medikamentösen Hochdrucktherapie der diastolische Blutdruck in den Keller geht, steigt das Risiko für schwere kardiovaskuläre Ereignisse: Darauf deutet eine Sekundäranalyse der SPRINT-Studie hin.
Insektenstiche sind bei Erwachsenen die häufigsten Auslöser einer Anaphylaxie. Einen wirksamen Schutz vor schweren anaphylaktischen Reaktionen bietet die allergenspezifische Immuntherapie. Jedoch kommt sie noch viel zu selten zum Einsatz.
Beginnen ältere Männer im Pflegeheim eine Antihypertensiva-Therapie, dann ist die Frakturrate in den folgenden 30 Tagen mehr als verdoppelt. Besonders häufig stürzen Demenzkranke und Männer, die erstmals Blutdrucksenker nehmen. Dafür spricht eine Analyse unter US-Veteranen.
