RESUMO
OBJECTIVES: Oligoarticular psoriatic arthritis (PsA) is frequent but rarely studied. The objective was to assess the efficacy of apremilast in early oligoarticular PsA. METHODS: FOREMOST (NCT03747939) was a phase 4 multicentre, randomised, double-blind, placebo-controlled trial. Patients had early (symptom duration ≤5 years) oligoarticular PsA (>1 but ≤4 swollen and >1 but ≤4 tender joints; 2-8 total active joints). Patients were randomised 2:1 to apremilast 30 mg two times per day or placebo for 24 weeks, with an early escape at week 16. The primary endpoint was the proportion of patients at week 16 who achieved minimal disease activity (MDA)-Joints (modification of MDA mandating ≤1 swollen joint and ≤1 tender joint) based on sentinel joints (those affected at baseline) with a combination of non-responder imputation and multiple imputations. Exploratory analysis assessed all joints. RESULTS: Of 308 patients randomised (apremilast: n=203; placebo: n=105), mean (SD) PsA duration was 9.9 (10.2) months, mean (SD) age was 50.9 (12.5) years and 39.9% of patients were using a conventional synthetic disease-modifying antirheumatic drug. MDA-Joints (sentinel joints (primary endpoint) and all joints) were achieved by significantly more patients with apremilast (33.9% and 21.3%) vs placebo (16.0% and 7.9%) at week 16 (p=0.0008 and nominal p=0.0028, respectively). Greater improvements in patient-reported outcomes, clinical disease activity and skin involvement were also seen with apremilast versus placebo. CONCLUSIONS: FOREMOST is the first randomised controlled trial designed for early oligoarticular PsA and showed apremilast improves clinical and patient-reported outcomes. This trial may inform the optimal management of PsA in these patients. TRIAL REGISTRATION NUMBER: NCT03747939.
RESUMO
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. TRIAL REGISTRATION: NCT02706873.

OBJECTIVES: Oral immune tolerance (OT) is a complex process with unknown genetic regulation. Our aim is to explore possible genetic control of OT in patients with rheumatoid arthritis (RA). METHODS: RA patients with increased interferon γ production invitro when their isolated peripheral blood mononuclear cells (PBMC) were cultured with type II bovine collagen α1 chain [α1 (II)] were enrolled in this study and were randomly assigned to the "Low dose" type II collagen (CII) group (30 µg/day for 10 weeks, followed by 50 µg/day for 10 weeks, followed by 70 µg/day for 10 weeks) or "High dose" CII group (90 µg/day for 10 weeks, followed by 110 µg/day for 10 weeks, followed by 130 µg/day for 10 weeks). Heparinized blood was obtained at baseline and after each of the 10 weeks treatment for analysis of the invitro production of IFNγ by their PBMC stimulated by α1(II) . Single nucleotide polymorphism (SNP) analysis of the responders and non-responders to oral CII was conducted using GeneChip Mapping 10 K 2.0 Array. RESULTS: The SNP A-15,737 was found to associate with the ability of CII to suppress IFNγ production by α1(CII)-stimulated RA PBMC. The potential for SNP A-15,737 to associate with the OT response for patients with another autoimmune disease [OT induced by oral type I bovine collagen (CI) in patients with diffuse cutaneous systemic sclersodid (dsSSc)] was also explored. CONCLUSIONS: The ROT1 region plays a role in the control of IFNγ production after oral dosing of auto-antigens, thereby determining if oral tolerance to that antigen will develop.
RESUMO
INTRODUCTION: Long-term therapeutic options providing durable response and tolerability are needed for psoriatic arthritis (PsA). The ongoing KEEPsAKE 2 trial is evaluating risankizumab treatment in patients with active PsA who previously had inadequate response/intolerance to ≥ 1 conventional synthetic disease-modifying antirheumatic drug (csDMARD-IR) and/or 1-2 biologic DMARDs (bDMARD-IR). Herein, we report results through 100 weeks of treatment. METHODS: KEEPsAKE 2 is a global phase 3 trial. Patients with active PsA were randomized 1:1 to double-blind subcutaneous risankizumab 150 mg or placebo (weeks 0, 4, and 16). At week 24, all patients received open-label risankizumab every 12 weeks until end of study. Efficacy endpoints included achieving ≥ 20% improvement in PsA symptoms using American College of Rheumatology criteria (ACR20), attaining minimal disease activity (MDA; meeting ≥ 5/7 criteria of low disease activity and extent), and improving in other measures. RESULTS: At the cutoff date, 345/443 (77.9%) patients were ongoing in the study. ACR20 was achieved in 57.1% and 52.5% of the continuous risankizumab and placebo/risankizumab cohorts, respectively, at week 100 and in 60.0% and 55.8%, respectively, at week 52. In week 52 responders, maintenance of ACR20 at week 100 was achieved in 74.8% (continuous risankizumab) and 78.7% (placebo/risankizumab) of patients. In the continuous risankizumab and placebo/risankizumab cohorts, respectively, MDA was achieved by 33.0% and 33.3% of patients at week 100 and by 27.2% and 33.8% at week 52. Among MDA responders at week 52, maintenance of MDA response was achieved by 83.6% and 73.0% of the continuous risankizumab and placebo/risankizumab cohorts, respectively. Risankizumab was well tolerated through week 100. CONCLUSIONS: Risankizumab demonstrated durable efficacy and tolerability through 100 weeks; most patients who achieved ACR20 and MDA responses at week 52 maintained this achievement through week 100. There were no new safety signals in patients who had csDMARD-IR and bDMARD-IR. TRIAL REGISTRATION: ClinicalTrials.gov NCT03671148.
Risankizumab, a biologic disease-modifying antirheumatic drug, helps control the body's immune system to reduce symptoms of psoriatic arthritis (a disease that inflames the joints of people who have the skin condition psoriasis). The ongoing KEEPsAKE 2 study is evaluating how well risankizumab works and how safe it is for treating adult patients with active psoriatic arthritis who previously experienced inadequate response to one or more specific types of disease-modifying anti-arthritis drugs. Patients were randomly assigned to receive either risankizumab or an inactive drug; after 24 weeks, all patients received risankizumab. At study week 100, 57% of patients who were assigned to receive continuous risankizumab since the start of the study experienced a 20% or more improvement in a measure of psoriatic arthritis symptoms using criteria established by the American College of Rheumatology (ACR20); a similar proportion of patients achieved a 20% improvement at both weeks 24 and 52. Similarly, 56% and 53% of patients who switched from inactive drug to risankizumab achieved ACR20 at weeks 52 and 100 (more than before switching to risankizumab at week 24). Minimal disease activity (MDA) was evaluated by assessing joint and skin symptoms, affected body surface area, pain, and physical function. At week 100, 33% of patients achieved MDA (both groups), which was similar to week 52. Most patients who achieved ACR20 or MDA at week 52 maintained responses at week 100. Improvements with risankizumab were seen in several other measures of treatment outcomes through week 100. Risankizumab was generally safe through 100 weeks.
RESUMO
OBJECTIVE: To assess the efficacy and safety of ABBV-3373, a novel antibody-drug conjugate (ADC) composed of the anti-tumor necrosis factor (anti-TNF) monoclonal antibody adalimumab linked to a glucocorticoid receptor modulator (GRM), compared to adalimumab, in patients with rheumatoid arthritis (RA). METHODS: In this randomized, double-blind, active-controlled, proof-of-concept trial (ClinicalTrials.gov identifier: NCT03823391), adults with moderate-to-severe RA receiving background methotrexate were administered intravenously (IV) ABBV-3373 100 mg every other week for 12 weeks, followed by placebo for 12 weeks, or subcutaneous adalimumab 80 mg every other week for 24 weeks. The primary end point was change from baseline in the Disease Activity Score in 28 joints using C-reactive protein (DAS28-CRP) at week 12, with 2 prespecified primary comparisons of ABBV-3373 versus historical adalimumab (80 mg every other week or equivalent dose) and versus combined in-trial/historical adalimumab. Secondary end points included change from baseline in the Clinical Disease Activity Index, Simplified Disease Activity Index, and DAS28 using erythrocyte sedimentation rate, as well as the proportion of patients achieving a DAS28-CRP of ≤3.2 and the American College of Rheumatology 50% improvement criteria. RESULTS: Forty-eight patients were randomized to receive either ABBV-3373 (n = 31) or adalimumab (n = 17). At week 12, ABBV-3373 demonstrated a reduction in DAS28-CRP compared to historical adalimumab (-2.65 versus -2.13; P = 0.022) and compared to combined in-trial/historical adalimumab (-2.65 versus -2.29; probability 89.9%), with numerically greater improvement than in-trial adalimumab (-2.51). For secondary end points, greater efficacy was observed with ABBV-3373 compared to historical adalimumab; ABBV-3373 was predicted with 79.3-99.5% probability to be more effective than adalimumab based on combined in-trial/historical adalimumab data. Of the ABBV-3373-treated patients who achieved DAS28-CRP ≤3.2 at week 12, 70.6% maintained this response at week 24 despite switching to placebo. Four serious adverse events (SAEs) were reported with ABBV-3373 (noncardiac chest pain, pneumonia, upper respiratory tract infection, and anaphylactic shock) and 2 SAEs with adalimumab (breast abscess and bronchitis). After increasing the duration of IV ABBV-3373 administration from 3 minutes to 15-30 minutes, no similar events of anaphylactic shock were reported. CONCLUSION: Data from this proof-of-concept trial support the continued development of a TNF-GRM ADC for the treatment of RA, with the potential to achieve superior outcomes compared to currently available therapies.

OBJECTIVE: PsA is a chronic inflammatory disease in which the skin and joints are affected. In this follow-up analysis, the 52-week efficacy and safety of risankizumab 150 mg in patients with active PsA who had previous inadequate response/intolerance to one or two biologic therapies (Bio-IR) or one or more conventional synthetic DMARDs (csDMARD-IR) were evaluated. METHODS: In the ongoing, phase 3, KEEPsAKE 2 trial, patients with active PsA were randomized 1:1 to receive subcutaneous risankizumab 150 mg or placebo at weeks 0, 4 and 16 (period 1). At week 24 (period 2), patients who received placebo were switched to risankizumab, and all patients received risankizumab 150 mg every 12 weeks from weeks 28 to 208. RESULTS: At week 24, 51.3% of risankizumab-treated patients (n = 224) achieved ≥20% improvement in ACR criteria (ACR 20) vs 26.5% of placebo-treated patients (n = 220; P < 0.001). At week 52, 58.5% of patients randomized to receive continuous risankizumab achieved ACR20, and 55.7% of patients who switched from placebo to risankizumab at week 24 achieved ACR20. Similar trends were observed for other efficacy measures. Rates of serious treatment-emergent adverse events (TEAEs) and TEAEs leading to discontinuation remained stable through week 52, and no deaths were reported. CONCLUSION: Risankizumab was well tolerated and improved symptoms of PsA in Bio-IR/csDMARD-IR patients, with a consistent long-term safety profile from weeks 24 to 52.

OBJECTIVES: Risankizumab is an interleukin-23 inhibitor under study for the treatment of patients with psoriatic arthritis (PsA). The phase 3 KEEPsAKE 2 trial investigated the efficacy and safety of risankizumab versus placebo in patients with active PsA who had previous inadequate response or intolerance to ≤2 biological therapies (Bio-IR) and/or ≥1 conventional synthetic disease-modifying antirheumatic drug (csDMARD-IR). Results through week 24 are reported here. METHODS: Adults with PsA who were Bio-IR and/or csDMARD-IR were randomised to receive subcutaneously administered risankizumab 150 mg or placebo at weeks 0, 4 and 16 during a 24-week, double-blind treatment period. The primary endpoint was the proportion of patients who achieved ≥20% improvement in American College of Rheumatology score (ACR20) at week 24. Secondary endpoints assessed key domains of PsA and patient-reported outcomes. RESULTS: A total of 444 patients (median age 53 years, range 23-84 years) were randomised to risankizumab (n=224) or placebo (n=220); 206 patients (46.5%) were Bio-IR. At week 24, a significantly greater proportion of patients receiving risankizumab achieved the primary endpoint of ACR20 (51.3% vs 26.5%, p<0.001) and all secondary endpoints (p<0.05) compared with placebo. Serious adverse events were reported for 4.0% and 5.5% of risankizumab-treated and placebo-treated patients, respectively; serious infections were reported for 0.9% and 2.3%, respectively. CONCLUSION: Treatment with risankizumab resulted in significant improvements versus placebo in key disease outcomes and was well tolerated in patients with PsA who were Bio-IR and/or csDMARD-IR.

OBJECTIVES: Apremilast monotherapy was evaluated up to 5 years in PALACE 4 (fourth PsA Long-term Assessment of Clinical Efficacy study) DMARD-naïve patients with PsA. METHODS: Patients with active PsA were randomized (1:1:1) to placebo, apremilast 30 mg or apremilast 20 mg twice a day. Placebo patients were rerandomized to apremilast at week 16 or 24. Double-blind apremilast continued to week 52, with a 4-year open-label extension (≤260 weeks of exposure). Analyses through week 260 were based on observed data. RESULTS: A total of 527 patients were treated. Among patients randomized to apremilast 30 mg at baseline, 45.5% completed week 260. At study end, 24.8% reported conventional synthetic DMARD or steroid use for any reason. At week 260, 65.8%/39.0%/20.3% of apremilast 30 mg patients achieved ACR20/ACR50/ACR70 responses, respectively. PsA sign and symptom improvements were sustained up to week 260 with continued treatment, including reductions in swollen (84.8%) and tender (76.4%) joint counts. Among apremilast 30 mg patients with baseline enthesitis or dactylitis, 71.2% achieved a Maastricht Ankylosing Spondylitis Enthesitis Score of 0 and 95.1% achieved a dactylitis count of 0. Over 50% of patients achieved a HAQ Disability Index minimal clinically important difference (≥0.35). In patients with ≥3% baseline psoriasis-involved body surface area, 60.3% and 47.6% achieved ≥50% and ≥75% improvement in Psoriasis Area and Severity Index scores, respectively. Patients continuing apremilast 20 mg also demonstrated consistent, sustained improvements. The most common adverse events were diarrhoea, nausea, headache, upper respiratory tract infection and nasopharyngitis. No new safety concerns were observed long term. CONCLUSIONS: Apremilast led to sustained PsA efficacy up to 260 weeks and was well tolerated. TRIAL REGISTRATION: ClinicalTrials.gov (http://clinicaltrials.gov), NCT01307423.

Objectives: To evaluate the safety and maintenance of efficacy with ABT-122, a bi-specific monoclonal antibody targeting TNF and IL-17A, in patients with RA or PsA in open-label, 24-week extensions [open-label extensions (OLEs)] of 12-week, randomized, double-blind studies. Methods: All patients received ABT-122 (RA, 120 mg; PsA, 240 mg) subcutaneously every other week on background MTX. Safety assessments included adverse events (AEs) and laboratory parameters. Efficacy was evaluated with ACR responses, 28-joint DAS using high-sensitivity CRP [DAS28 (hsCRP)], and Psoriasis Area and Severity Index (PsA study). Results: The RA OLE study enrolled 158 patients; the PsA OLE study enrolled 168 patients. In the RA OLE study, the incidence of treatment emergent AEs (TEAEs; 41%) appeared similar to the double-blind study (36-43%). In the PsA OLE study, 57% of patients reported ⩾1 TEAE (double-blind study, 42-53%). Most TEAEs were mild or moderate in severity. There were no neutrophil abnormalities greater than grade 2. Grade 3 and/or 4 laboratory abnormalities were reported for lymphocytes, alanine aminotransferase, aspartate aminotransferase, bilirubin and haemoglobin; the number of these severe laboratory values was low (0.6-3.0%), except grade 3 lymphocyte count decreased (11.5%) in the RA study. In both OLE studies, efficacy assessed by ACR responses and other disease activity scores was maintained over the 24 weeks. Conclusion: ABT-122 demonstrated acceptable tolerability and maintenance of efficacy for up to 36 weeks in patients with RA or PsA receiving background MTX. Trial registration: ClinicalTrials.gov, http://clinicaltrials.gov, NCT02433340 and NCT02429895.

OBJECTIVE: Tumor necrosis factor (TNF) and interleukin-17A (IL-17A) may independently contribute to the pathophysiology of rheumatoid arthritis (RA). This study sought to evaluate the safety and efficacy of ABT-122, a novel dual variable domain immunoglobulin targeting human TNF and IL-17A, in patients with RA who have experienced an inadequate response to methotrexate. METHODS: Patients with active RA who were receiving treatment with methotrexate and had no prior exposure to biologic agents (n = 222) were enrolled in a 12-week phase II randomized, double-blind, active-controlled, parallel-group study. Patients were randomized to receive either ABT-122 at dosages of 60 mg every other week, 120 mg every other week, or 120 mg every week or adalimumab at 40 mg every other week, administered subcutaneously. The primary efficacy end point was the proportion of patients achieving a ≥20% improvement response based on the American College of Rheumatology criteria for 20% improvement (ACR20) at week 12. RESULTS: Treatment-emergent adverse events were similar across all treatment groups, with no serious infections or systemic hypersensitivity reactions reported with ABT-122. ACR20 response rates at week 12 were 62%, 75%, and 80% with ABT-122 60 mg every other week, 120 mg every other week, and 120 mg every week, respectively, compared with an ACR20 response rate of 68% with 40 mg adalimumab every other week. The corresponding response rates for ACR50 and ACR70 improvement in the ABT-122 dose groups and adalimumab group were 35%, 46%, 47%, and 48%, respectively, and 22%, 18%, 36%, and 21%, respectively. CONCLUSION: Over the 12-week study period, dual inhibition of TNF and IL-17A with ABT-122 produced a safety profile consistent with that of adalimumb used for inhibition of TNF alone. The efficacy of ABT-122 over 12 weeks at dosages of 120 mg every other week or 120 mg every week was not meaningfully differentiated from that of adalimumab at a dosage of 40 mg every other week in patients with RA receiving concomitant methotrexate.

OBJECTIVES: The PALACE 4 trial evaluated apremilast monotherapy in patients with active PsA who were DMARD-naive. METHODS: Eligible patients were randomized (1:1:1) to placebo, apremilast 20 mg twice a day or apremilast 30 mg twice a day. At week 16 or 24, placebo patients were rerandomized to apremilast. Double-blind apremilast treatment continued to week 52, with extension up to 4 years. The primary endpoint was the proportion of patients achieving ⩾20% improvement in ACR response criteria (ACR20) at week 16; secondary endpoints included the mean change in the HAQ Disability Index (HAQ-DI) score at week 16. RESULTS: A total of 527 patients with mean disease duration of 3.4 years and high disease activity were randomized and received treatment. More apremilast patients achieved ACR20 response at week 16 [placebo, 15.9%; 20 mg, 28.0% (P = 0.0062); 30 mg, 30.7% (P = 0.0010)]. The mean HAQ-DI improvements were -0.17 (20 mg; P = 0.0008) and -0.21 (30 mg; P < 0.0001) vs 0.03 (placebo). Both apremilast doses showed significant ACR50 responses vs placebo at week 16 and improvements in secondary efficacy measures (swollen/tender joint counts) and psoriasis assessments, with sustained improvements through week 52. Common adverse events (AEs) over 52 weeks were diarrhoea, nausea, headache and upper respiratory tract infection; most events were mild or moderate. Serious AEs and AEs leading to discontinuation were comparable between groups. Laboratory abnormalities were infrequent and transient. CONCLUSIONS: In DMARD-naive patients, apremilast monotherapy improved PsA signs/symptoms over 52 weeks and was generally well tolerated. TRIAL REGISTRATION: ClinicalTrials.gov (http://clinicaltrials.gov), NCT01307423.
RESUMO
OBJECTIVE: Evaluate apremilast efficacy across various psoriatic arthritis (PsA) manifestations beginning at week 2 in biological-naïve patients with PsA. METHODS: Patients were randomised (1:1) to apremilast 30 mg twice daily or placebo. At week 16, patients whose swollen and tender joint counts had not improved by ≥10% were eligible for early escape. At week 24, all patients received apremilast through week 52. RESULTS: Among 219 randomised patients (apremilast: n=110; placebo: n=109), a significantly greater American College of Rheumatology 20 response at week 16 (primary outcome) was observed with apremilast versus placebo (38.2% (42/110) vs 20.2% (22/109); P=0.004); response rates at week 2 (first assessment) were 16.4% (18/110) versus 6.4% (7/109) (P=0.025). Improvements in other efficacy outcomes, including 28-joint count Disease Activity Score (DAS-28) using C reactive protein (CRP), swollen joint count, Health Assessment Questionnaire-Disability Index (HAQ-DI), enthesitis and morning stiffness severity, were observed with apremilast at week 2. At week 16, apremilast significantly reduced PsA disease activity versus placebo, with changes in DAS-28 (CRP) (P<0.0001), HAQ-DI (P=0.023) and Gladman Enthesitis Index (P=0.001). Improvements were maintained with continued treatment through week 52. Over 52 weeks, apremilast's safety profile was consistent with prior phase 3 studies in psoriasis and PsA. During weeks 0-24, the incidence of protocol-defined diarrhoea was 11.0% (apremilast) and 8.3% (placebo); serious adverse event rates were 2.8% (apremilast) and 4.6% (placebo). CONCLUSIONS: In biological-naïve patients with PsA, onset of effect with apremilast was observed at week 2 and continued through week 52. The safety profile was consistent with previous reports.

INTRODUCTION: 'REASSURE' (NCT01377012), a phase 3 study, evaluated the efficacy and safety of secukinumab in patients with active rheumatoid arthritis (RA) who had an inadequate response to, or intolerance of, tumor necrosis factor inhibitors (TNF-inhibitors). METHODS: A total of 637 patients were randomized (1:1:1) to receive intravenous secukinumab 10 mg/kg (baseline, weeks 2 and 4) followed by subcutaneous secukinumab 150 mg or 75 mg every 4 weeks (starting from week 8) or placebo at the same dosing schedule. The primary endpoint was the American College of Rheumatology 20% improvement criteria (ACR20) at week 24. Other predefined hierarchical endpoints included Health Assessment Questionnaire-Disability Index, van der Heijde modified total Sharp score (vdH-mTSS) at week 24, and major clinical response (MCR; continuous 6 month period of ACR70 response) at 1 year. RESULTS: The primary efficacy endpoint was met with both secukinumab dose groups: ACR20 response rate at week 24 was 35.2% for both secukinumab dose groups (P = 0.0009) vs 19.6% for placebo. The improvements in secondary endpoints were greater in the secukinumab dose groups vs placebo but did not meet statistical significance. The overall safety profile was similar across all treatment groups. CONCLUSION: Secukinumab demonstrated efficacy in reducing disease activity over placebo as measured by ACR20 in patients with active RA who had an inadequate response to TNF-inhibitors. Secukinumab demonstrated a safety profile similar to other biologics currently approved for RA. FUNDING: Novartis Pharma AG. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01377012.
RESUMO
BACKGROUND: There is significant unmet need in patients with ankylosing spondylitis (AS) who have inadequate response or intolerance to anti-tumour necrosis factor (TNF) treatment. Secukinumab, an anti-interleukin-17A monoclonal antibody, significantly improved signs and symptoms of AS in the MEASURE 2 study (NCT01649375). METHODS: Subjects with active AS (N=219) received secukinumab (150 or 75â mg) or placebo at baseline, weeks 1, 2, 3 and 4, and every 4â weeks thereafter. Randomisation was stratified by prior anti-TNF use: anti-TNF-naive or inadequate response/intolerance to one anti-TNF (anti-TNF-IR). The primary endpoint was Assessment of SpondyloArthritis International Society criteria (ASAS) 20 at week 16. RESULTS: At week 16, 68.2% of anti-TNF-naive subjects treated with secukinumab 150â mg achieved ASAS20 compared with 31.1% treated with placebo (p<0.001). In the anti-TNF-IR group, 50.0% of subjects treated with secukinumab 150â mg achieved an ASAS20 response compared with 24.1% treated with placebo (p<0.05). Numerically greater improvements were observed with secukinumab than with placebo for most secondary endpoints. Clinical responses were sustained through week 52. CONCLUSIONS: Secukinumab 150â mg provided sustained improvements in signs and symptoms of AS in anti-TNF-naive and anti-TNF-IR subjects through 52â weeks of therapy. TRIAL REGISTRATION NUMBER: NCT01649375.

OBJECTIVE: To evaluate subcutaneous SBI-087 to treat rheumatoid arthritis (RA). METHODS: A total of 210 adult patients with active RA were randomized to receive either 200 mg SBI-087 or placebo (Pbo), according to one of these patterns: SBI/Pbo/Pbo (SBI on Day 1), SBI/SBI/Pbo (SBI days 1 and 15), SBI/Pbo/SBI (SBI days 1 and 84), SBI/SBI/SBI (SBI days 1, 15, and 84), or Pbo/Pbo/Pbo (Pbo all 3 days). All patients were seropositive and taking background methotrexate. The primary endpoint was proportion of patients achieving 20% improvement from baseline at Week 16 by American College of Rheumatology criteria (ACR20). Other outcomes included 28-joint Disease Activity Score (DAS28)-C-reactive protein (CRP), physician's and patient's global assessments of disease activity (PGA and PtGA, respectively) and Health Assessment Questionnaire-Disability Index (HAQ-DI). Peripheral CD19+ B cells were measured by high-sensitivity flow cytometer. Statistical significance was set at 2-sided α 0.10 level. RESULTS: The SBI/SBI/SBI group demonstrated significant improvement in ACR20 and DAS28-CRP from Week 8 onward, sustained improvement in CRP levels from Week 12 onward, and significant improvements in PGA and PtGA in weeks 16 through 24, and in HAQ-DI at Week 24. The SBI/Pbo/Pbo and SBI/SBI/Pbo groups did not meet the primary endpoint but demonstrated improvements in several secondary endpoints. All treatment groups exhibited depletion of peripheral CD19+ B cells throughout the study. Overall, 61.5% of patients receiving SBI-087 and 55.0% of patients receiving Pbo reported adverse events. CONCLUSION: SBI-087 effectively depleted peripheral CD20 B cells and was well tolerated. Improvements were consistently observed in the SBI/SBI/SBI group for the majority of efficacy and quality-of-life outcomes.

OBJECTIVE: To evaluate apremilast treatment in patients with active psoriatic arthritis, including current skin involvement, despite prior therapy with conventional disease-modifying antirheumatic drugs and/or biologic agents. METHODS: Patients (N=505) were randomised (1:1:1) to placebo, apremilast 20â mg twice daily, or apremilast 30â mg twice daily. Rescue therapy with apremilast was designated at week 16 for placebo patients not achieving 20% improvement in swollen and tender joint counts. At week 24, the remaining placebo patients were then randomised to apremilast 20â mg twice daily or 30â mg twice daily. The efficacy and safety of apremilast were assessed over 52â weeks. RESULTS: At week 16, significantly more patients receiving apremilast 20â mg twice daily (28%) and 30â mg twice daily (41%) achieved 20% improvement in American College of Rheumatology response criteria versus placebo (18%; p=0.0295 and p<0.0001, respectively), and mean decrease in the Health Assessment Questionnaire-Disability Index score was significantly greater with apremilast 30â mg twice daily (-0.20) versus placebo (-0.07; p=0.0073). In patients with baseline psoriasis body surface area involvement ≥3%, significantly more apremilast 30â mg twice daily patients achieved 50% reduction from baseline Psoriasis Area and Severity Index score (41%) versus placebo (24%; p=0.0098) at week 16. At week 52, observed improvements in these measures demonstrated sustained response with continued apremilast treatment. Most adverse events were mild to moderate in severity; the most common were diarrhoea, nausea, headache and upper respiratory tract infection. CONCLUSIONS: Apremilast demonstrated clinically meaningful improvements in psoriatic arthritis and psoriasis at week 16; sustained improvements were seen with continued treatment through 52â weeks. Apremilast was generally well tolerated and demonstrated an acceptable safety profile. TRIAL REGISTRATION NUMBER: NCT01212770.

OBJECTIVE: To evaluate the longer-term safety and efficacy of secukinumab, a fully human monoclonal antiinterleukin-17A antibody, in patients with rheumatoid arthritis. METHODS: In this 52-week, double-blind, placebo-controlled (up to Week 20) study (NCT00928512), patients responding inadequately to disease-modifying antirheumatic drugs (DMARD) or biologics were randomized to receive monthly subcutaneous injections of secukinumab (25, 75, 150, or 300 mg), or placebo. The efficacy and safety results up to Week 20 have been reported previously. Here, efficacy results from Week 20 to 52 and safety results from Week 20 to 60 are presented. RESULTS: Of 237 patients randomized, 174 (73.4%) completed the study. Patients with improved American College of Rheumatology (ACR) and 28-joint Disease Activity Score (DAS28) C-reactive protein (CRP) responses at Week 16 sustained their responses through Week 52. In patients taking 150 mg of secukinumab, responses were improved through Week 52 (ACR50: Week 16 = 45%, Week 52 = 55%; DAS28-CRP ≤ 2.6: Week 16 = 25%, Week 52 = 40%). The rate of adverse events (AE) from weeks 20 to 60 was 64.8%, with most AE being mild to moderate in severity. The overall rate of infections was 31.9%, most being mild. The most predominant infection was nasopharyngitis, and was not associated with dose or concurrent neutropenia. Serious AE were reported in 21 patients (8.9%). There were 3 reports of malignancies (ovarian, lung, basal cell), and no deaths between weeks 20 and 60. CONCLUSION: Patients with active RA who failed to respond to DMARD and other biologics showed an improvement after longterm treatment with 150 mg of secukinumab. The frequency of AE remained stable over time and secukinumab had a consistent safety profile over 60 weeks.

OBJECTIVE: To assess the safety and efficacy of secukinumab, a fully human monoclonal anti-interleukin-17A antibody, in patients with rheumatoid arthritis (RA). METHODS: Patients (n=237) with inadequate response to methotrexate were randomly assigned to receive monthly subcutaneous injections of secukinumab 25 mg, 75 mg, 150 mg, 300 mg or placebo. The primary endpoint was the American College of Rheumatology 20% response (ACR20) at week 16. RESULTS: Demographics and baseline characteristics were comparable across all treatment groups. The primary efficacy endpoint was not achieved: the proportion of ACR20 responders at week 16 with secukinumab 25-300 mg was 36.0-53.7% versus placebo (34%). Disease activity score in 28 joints (DAS28)-C-reactive protein (CRP) was a secondary endpoint and clinically relevant decreases with secukinumab 75-300 mg were reported versus placebo. Serum high sensitivity CRP levels at week 16 were significantly reduced with secukinumab 75 mg, 150 mg and 300 mg doses versus placebo. The safety profile of secukinumab was consistent with that seen with other biological agents. Most adverse events (AE) were mild to moderate in severity. Infections were slightly more frequent with secukinumab than placebo. Six serious AE were reported: secukinumab 75 mg (one), secukinumab 300 mg (four) and placebo (one). CONCLUSIONS: ACR20 response rates differed between secukinumab 75 mg, 150 mg and 300 mg doses and placebo; however, the primary efficacy endpoint was not achieved. Greater decreases in DAS28 were observed with secukinumab 75 mg, 150 mg and 300 mg than placebo. There were no unexpected safety signals and no specific organ-related toxicities. Further trials with secukinumab in the treatment of RA are warranted.
