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. [ABSTRACT FROM AUTHOR]

Objective: To investigate the clinical response at week 52 in patients with ankylosing spondylitis (AS) who received secukinumab 300 vs 150 mg after inadequate response to 150 mg at week 16., Methods: ASLeap (NCT03350815) was a randomized, double-blind, parallel-group, multicentre, phase 4 trial. After 16 weeks of open-label secukinumab 150 mg (Treatment Period 1), patients who did not achieve inactive disease (Ankylosing Spondylitis Disease Activity Score [ASDAS] <1.3) at both Weeks 12 and 16 were considered to have an inadequate response and were randomized 1:1 to receive secukinumab 300 or 150 mg every 4 weeks until week 52 (Treatment Period 2). The primary efficacy variable was achievement of ASDAS <1.3 at week 52 using week 16 as baseline. Safety was evaluated by the incidence of treatment-emergent adverse events through week 52., Results: Of 322 patients treated with secukinumab in Treatment Period 1, 207 (64.3%) had inadequate response. Similar proportions of patients with inadequate response randomized to secukinumab 300 mg (n = 101) and 150 mg (n = 105) in Treatment Period 2 completed the study (83.8% and 84.3%, respectively). At week 52, 8.8% and 6.7% of patients receiving secukinumab 300 and 150 mg, respectively, achieved ASDAS <1.3. The incidence of treatment-emergent adverse events was similar in both groups through week 52. No new safety signals were observed., Conclusion: Patients with AS who did not achieve ASDAS <1.3 after receiving secukinumab 150 mg for 16 weeks experienced similar clinical response and safety through week 52 regardless of dose escalation., Trial Registration: ClinicalTrials.gov, NCT03350815., (© The Author(s) 2024.

Objectives: Evaluate the efficacy and safety of the Janus kinase-1 inhibitor filgotinib in Japanese patients with rheumatoid arthritis (RA) and inadequate response to methotrexate (MTX)., Methods: Data from 147 Japanese patients in FINCH 1, a 52-week global Phase 3 study, were analysed up to 24 weeks. Patients received once-daily filgotinib 200 or 100 mg, biweekly adalimumab, or placebo, all with stable background MTX., Results: In the Japanese population, American College of Rheumatology 20% response rates at Week 12 (primary endpoint) were 77.5%, 65.9%, 53.6%, and 36.8% for filgotinib 200 mg, filgotinib 100 mg, adalimumab, and placebo. Proportions of patients achieving Disease Activity Score with 28 joints <2.6 at Week 24: filgotinib 200 mg, 65.0%; filgotinib 100 mg, 51.2%; adalimumab, 42.9%; and placebo, 5.3%. Incidence rates of serious infections: filgotinib 200 mg, 2.5%; filgotinib 100 mg, 0%; adalimumab, 10.7%; and placebo, 5.3%. Treatment-emergent laboratory abnormalities Grade ≥3 occurred in five (12.5%) filgotinib 200 mg, three (7.3%) filgotinib 100 mg, one (3.6%) adalimumab, and no placebo patients. No deaths were reported among Japanese patients., Conclusions: Filgotinib once daily combined with MTX was effective and generally safe and well tolerated up to Week 24 in Japanese patients with RA and inadequate response to MTX., (© Japan College of Rheumatology 2022.

Background: Secukinumab is an interleukin-17A inhibitor used in the treatment of patients with active psoriatic arthritis. In the phase 3 FUTURE 2 trial, secukinumab showed sustained improvement in clinical outcomes over 2 years. Because scarce data exists on the long-term treatment with biological therapies in patients with psoriatic arthritis, we aimed to assess and describe the 5-year (end-of-study) results on the efficacy and safety of secukinumab 300 mg and 150 mg doses, as well as dose escalation, from the FUTURE 2 study., Methods: FUTURE 2 is a phase 3, double-blind, placebo-controlled study done at 76 centres in Asia, Australia, Canada, Europe, and the USA. Patients with active psoriatic arthritis aged 18 years or older were randomly assigned to either secukinumab (300 mg, 150 mg, or 75 mg) or placebo weekly from baseline and then every 4 weeks from week 4. Secukinumab dose was escalated from 150 mg to 300 mg and from 75 mg to 150 mg or 300 mg starting at week 128, if active signs of disease were observed in patients, on the basis of the physician's assessment, with the escalated dose maintained thereafter. We assessed key efficacy endpoints at week 260 (5 years) for secukinumab 300 mg and 150 mg, including American College of Rheumatology (ACR) and Psoriasis Area and Severity Index (PASI) responses. The safety analysis included all patients who received one or more doses of secukinumab. We report data as observed. This study is registered with ClinicalTrials.gov, NCT01752634., Findings: At randomisation, 65% of patients were naive to tumour necrosis factor inhibitors and 47% were receiving concomitant methotrexate. Of 397 patients randomly assigned in FUTURE 2, 248 (62%) completed 5 years of treatment, including 64 (64%) of 100 patients in the original secukinumab 300 mg group, 65 (65%) of 100 in the 150 mg group, 59 (60%) of 99 in the 75 mg group, and 60 (61%) of 98 in the placebo group. Overall, 127 (52%) of 242 patients required dose escalation during the study. ACR responses at 5 years were 71 (74%; ACR20), 50 (52%; ACR50), and 31 (32%; ACR70) of 96 evaluable patients in the secukinumab 300 mg group, and 67 (70%; ACR20), 41 (43%; ACR50), and 28 (29%; ACR70) of 96 evaluable patients in the secukinumab 150 mg group. From 24 to 32 weeks and from 48 to 84 weeks after dose escalation from secukinumab 150 mg to 300 mg, the proportions of ACR and PASI non-responders decreased, whereas the proportions of ACR and PASI responders increased. During the entire treatment period, the most frequent treatment-emergent serious adverse event was serious infection (exposure-adjusted incidence 1·7, 95% CI 1·1-2·5; n=25) in the any secukinumab group. No new or unexpected safety signals were reported., Interpretation: Secukinumab 300 mg and 150 mg provided sustained improvement in the signs and symptoms of psoriatic arthritis, with consistent safety over 5 years. This study supports the clinical benefit and safety of long-term treatment with secukinumab in patients with psoriatic arthritis., Funding: Novartis., (Copyright © 2020 Elsevier Ltd.

Introduction: Spebrutinib (CC-292) is an orally administered, covalent, small-molecule inhibitor of Bruton's tyrosine kinase (BTK), part of the B-cell and Fc receptor signaling pathways. This study evaluated spebrutinib pharmacology and mechanism of action over a 4-week treatment period in patients with active rheumatoid arthritis (RA)., Methods: Primary human B cells, T cells, natural killer cells, macrophages, dendritic cells, basophils, and osteoclasts were treated with spebrutinib in vitro. Clinical pharmacodynamics were studied in 47 patients with active RA on background methotrexate therapy randomized to oral spebrutinib 375 mg/day or placebo., Results: In vitro, spebrutinib inhibited B-cell proliferation more potently than T-cell proliferation and reduced both lymphoid and myeloid cytokine production and degranulation, as well as osteoclastogenesis. Clinical efficacy trended higher in spebrutinib-treated RA patients, with 41.7% (10/24) achieving ≥ 20% improvement in ACR response criteria (ACR20) versus 21.7% (5/23) of placebo patients at week 4 (P = 0.25). Treatment-emergent adverse events were comparable between treatment groups. In spebrutinib-treated patients, median BTK occupancy in peripheral blood was 83%, and significant increases in total CD19 + and mature-naive CD27 - CD38 - IgD + B cells and decreases in transitional CD27 - CD38 + B cells were observed. Spebrutinib significantly reduced serum chemokines chemokine ligand 13 (CXCL13), macrophage inflammatory protein-1β (MIP-1β), and the bone resorption biomarker carboxy-terminal collagen cross-linking telopeptide (CTX-I) (P < 0.05). Clinical response to spebrutinib was associated with lower increases in CD19 + B cells and greater decreases in CXCL13 and MIP-1β from baseline to week 4. High CD19 + B cells and low CTX-I at baseline were associated with better spebrutinib clinical response., Conclusions: Spebrutinib inhibited various leukocyte responses in vitro, including those of B cells and osteoclasts. In this small study in RA patients, spebrutinib was well tolerated, showed a downward trend for symptoms, significantly modulated B-cell populations, and reduced markers of chemotaxis and osteoclast activity., Trial Registration: NCT01975610.

Background: Primary Sjögren's syndrome is an autoimmune disease that presents as dryness of the mouth and eyes due to impairment of the exocrine glands. To our knowledge, no systemic therapies for primary Sjögren's syndrome have shown efficacy. CD40-CD154-mediated T cell-B cell interactions in primary Sjögren's syndrome contribute to aberrant lymphocyte activation in inflamed tissue, leading to sialadenitis and other tissue injury. Therefore, we investigated the safety and preliminary efficacy of iscalimab (CFZ533), a novel anti-CD40 monoclonal antibody, in patients with primary Sjögren's syndrome., Methods: This multicentre, randomised, double-blind, placebo-controlled, proof-of-concept study took place at ten investigational sites across Europe (UK, n=4; Germany, Switzerland, and Hungary, n=1 each) and the USA (n=3). Eligible patients were aged 18-75 years and fulfilled the 2002 American European consensus group diagnostic classification criteria for primary Sjögren's syndrome. In the double-blind phase of the trial, patients were randomly assigned (2:1) via computer-generated unique randomisation numbers to receive subcutaneous iscalimab (3 mg/kg) or placebo at weeks 0, 2, 4, and 8 (cohort 1) or intravenous iscalimab (10 mg/kg) or placebo at weeks 0, 2, 4, and 8 (cohort 2). Randomisation was stratified according to baseline intake of oral corticosteroids. At week 12, patients in both cohorts received open-label iscalimab (same dose and route) for 12 weeks. The primary objectives of the study were to assess the safety, tolerability, and efficacy of multiple doses of iscalimab in the two sequential dose cohorts. Safety and tolerability were assessed by adverse events and efficacy of iscalimab versus placebo was assessed by clinical disease activity, as measured by the change in European League Against Rheumatism Sjögren's syndrome disease activity index (ESSDAI) score after 12 weeks of treatment. Analyses were done on a per-protocol basis. The trial was registered with ClinicalTrials.gov, NCT02291029., Findings: Between Oct 22, 2014, and June 28, 2016, we assessed 82 patients for eligibility (25 for cohort 1 and 57 for cohort 2). 38 patients were excluded because of ineligibility. In cohort 1, 12 patients were randomly assigned to receive either 3 mg/kg doses of iscalimab (n=8) or placebo (n=4), and in cohort 2, 32 patients were randomly assigned to receive either intravenous 10 mg/kg doses of iscalimab (n=21) or placebo (n=11). Adverse events were similar between iscalimab treatment groups and placebo groups, with adverse events occurring in all patients in cohort 1, and in 52% and 64% of the iscalimab and placebo groups, respectively, in cohort 2. Two serious adverse events were reported (one case of bacterial conjunctivitis in cohort 1 and one case of atrial fibrillation in cohort 2), which were unrelated to treatment with iscalimab. Intravenous treatment with iscalimab resulted in a mean reduction of 5·21 points (95% CI 0·96-9·46; one-sided p=0·0090) in ESSDAI score compared with placebo. There was no signficiant difference in ESSDAI score between subcutaneous iscalimab and placebo., Interpretation: To our knowledge, this is the first randomised, placebo-controlled proof-of-concept study of a new investigational drug for primary Sjögren's syndrome that indicates preliminary efficacy. Our data suggest a role of CD40-CD154 interactions in primary Sjögren's syndrome pathology and the therapeutic potential for CD40 blockade in this disease should be investigated further., Funding: Novartis Pharma., (Copyright © 2020 Elsevier Ltd.

Introduction: In clinical trials for knee osteoarthritis (OAK), rescue medication is commonly provided to manage uncontrolled index-knee pain. The impact of treatment on rescue medication utilization provides important information on the robustness of analgesic effect. In randomized controlled OAK trials (NCT01487161, NCT02116972, NCT02357459), intra-articular (IA) triamcinolone acetonide extended-release (TA-ER) demonstrated substantial, prolonged analgesia versus saline-placebo and TA crystalline solution (TAcs) as assessed by patient-reported pain scales. This pooled analysis assessed the impact of TA-ER on rescue medication use., Methods: Patients (N = 798) with OAK (American College of Rheumatology criteria; Kellgren-Lawrence grade 2/3) and baseline average daily pain intensity score ≥ 5 to ≤ 9 (0-10 numeric rating scale) received a single IA injection of TA-ER (N = 324), saline-placebo (N = 262), or TAcs (N = 212). Acetaminophen/paracetamol tablets were provided to treat uncontrolled pain (knee or otherwise). Rescue medication consumption was monitored through a daily diary; pill counts were confirmed at the clinical site. Differences in rescue medication use were measured by least-squares mean (LSM) differences, number of rescue medication tablets used per day, and in area under the effect (AUE) curves of rescue medication tablets used per week., Results: The overall number of rescue medication tablets used per day through week 24 was significantly less (p ≤ 0.05) for TA-ER versus saline-placebo (LSM difference, - 0.43) and TAcs (- 0.24). Rescue medication use was significantly (p ≤ 0.05) lower following TA-ER versus saline-placebo across weeks 1-12 (AUE weeks1-12 ; LSM difference, - 24.5) and weeks 1-24 (AUE weeks1-24 ; - 51.6) and versus TAcs across weeks 1-12 (AUE weeks1-12 ; - 21.1)., Conclusions: In patients with painful OAK, reduced rescue medication use may be a potential benefit of TA-ER and further supports its analgesic efficacy. Additional research is needed to assess whether TA-ER impacts the use of other common oral analgesics (nonsteroidal anti-inflammatory drugs, opioids) for patients with OAK., Funding: Flexion Therapeutics, Inc., Burlington, MA, USA.

Introduction: Peficitinib is a novel orally bioavailable, once-daily Janus kinase (JAK) inhibitor approved in Japan for the treatment of rheumatoid arthritis (RA). This 2-year extension study of two global phase IIb trials investigated the long-term safety and effectiveness of peficitinib., Methods: All eligible patients with moderate-to-severe RA including patients in the placebo group who participated in one of two global phase IIb trials ('with methotrexate' or 'without methotrexate') were included in this 2-year open-label extension study and were converted to peficitinib 100 mg once daily. The primary objective was to evaluate an additional 2 years of safety by assessing treatment-emergent adverse events (AEs) and clinical laboratory evaluations for 105 weeks. Evaluation of an additional 2 years of effectiveness using American College of Rheumatology (ACR) 20/50/70 responses was the exploratory objective., Results: Overall, 611 patients were enrolled in the extension study: 319 (52.2%) patients completed the study and 292 (48%) discontinued treatment, including for withdrawal of patient consent (n = 96), failure to achieve low disease activity (n = 62), and AE not including death (n = 41). AEs were reported in 463 (76%) patients. The most common AEs (per 100 patient-years) were upper respiratory tract infections (9.9) and urinary tract infections (7.2). Serious AEs were reported in 80 (13%) patients, with incidences per 100 patient-years of serious infections 2.7, herpes zoster 1.5 (including one herpes zoster ophthalmic), and malignancies 0.6 (most frequently basal cell carcinoma). At week 105, 269 (44%) patients demonstrated an ACR20 response relative to their respective phase IIb trial baselines., Conclusion: Among 319 patients who completed this 2-year extension of two global phase IIb studies, peficitinib 100 mg once daily demonstrated a stable safety profile and sustained effectiveness in patients with moderate-to-severe RA., Trial Registration: ClinicalTrials.gov identifier, NCT01711814.

Introduction: To assess the efficacy and safety of the subcutaneous (s.c.) secukinumab 150 mg with loading (150 mg) or without loading (150 mg no-load) regimen through 104 weeks in patients with active psoriatic arthritis (PsA) in the FUTURE 4 (NCT02294227) study., Methods: Patients with PsA (N = 341) were randomized to s.c. secukinumab 150 mg, 150 mg no-load or placebo at baseline, weeks 1, 2, 3 and every 4 weeks thereafter. All placebo patients were reassigned to secukinumab 150 mg no-load at either week 16 (non-responders) or week 24 (responders). The primary end point was ACR20 at week 16. Patients could have their dose escalated from 150 to 300 mg based on their physician's decision starting at week 36. Pre- and post-escalation ACR and PASI responses were also assessed., Results: A total of 95.6% (326/341), 84.5% (288/341) and 79.8% (272/341) patients completed 16, 52 and 104 weeks of treatment, respectively. The primary end point was met; ACR20 response rate at week 16 was 41.2% and 39.8% with the 150 mg and 150 mg no-load groups, respectively, versus placebo (18.4%; adjusted P value = 0.0003 for both treatment arms). Efficacy responses observed at week 16 in both treatment regimens were sustained up to week 52 and 104, with many patients continuing to show improvements up to week 104. After dose escalation to 300 mg, the proportion of patients with non-/low-level ACR/PASI response decreased with increasing proportions of patients having higher ACR/PASI responses. No new or unexpected safety signals were reported., Conclusion: The secukinumab 150 mg or 150 mg no-load regimen demonstrated significant and sustained improvements in the signs and symptoms of psoriatic arthritis through 104 weeks; the loading regimen was associated with numerically higher and earlier responses for some high-hurdle end points. Improved efficacy was observed upon dose escalation from 150 to 300 mg. The safety profile was consistent with previous reports., Trial Registration: ClinicalTrials.gov identifier, NCT02294227., Funding: Novartis Pharma AG, Basel, Switzerland.

Introduction: Osteoarthritis (OA) is common and its prevalence is increased in military service members. In a phase 3 randomized controlled trial (NCT02357459), a single intra-articular injection of an extended-release formulation of triamcinolone acetonide (TA-ER) in participants with unilateral or bilateral knee OA demonstrated substantial improvement in pain and symptoms. Bilateral knee pain has emerged as a confounding factor in clinical trials when evaluating the effect of a single intra-articular injection. Furthermore, unilateral disease is frequently first to emerge in active military personnel secondary to prior traumatic joint injury. In this post hoc analysis, we assessed efficacy and safety of TA-ER in a subgroup of participants with unilateral knee OA., Methods: Participants ≥ 40 years of age with symptomatic knee OA were randomized to a single intra-articular injection of TA-ER 32 mg, TA crystalline suspension (TAcs) 40 mg, or saline-placebo. Average daily pain (ADP)-intensity and rescue medication use were collected at each of weeks 1-24 postinjection; Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)-A (pain), WOMAC-B (stiffness), WOMAC-C (function), and Knee Injury and Osteoarthritis Outcome Score Quality of Life (KOOS-QoL) were collected at weeks 4, 8, 12, 16, 20, and 24 postinjection. Adverse events (AEs) were assessed throughout the study. Participants with unilateral knee OA were selected for this analysis., Results: Of 170 participants with unilateral OA (TA-ER, N = 51; saline-placebo, N = 60; TAcs, N = 59), 42% were male and 89% were white. TA-ER significantly (p < 0.05) improved ADP-intensity vs. saline-placebo (weeks 1-24) and TAcs (weeks 4-21). TA-ER significantly (p < 0.05) improved WOMAC-A vs. saline-placebo (all time points) and TAcs (weeks 4, 8, 12, 24). Consistent outcomes were observed for rescue medication, WOMAC-B, WOMAC-C, and KOOS-QoL. AEs were similar in frequency/type across treatments., Conclusion: TA-ER provided 5-6 months' pain relief that consistently exceeded saline-placebo and TAcs, suggesting that TA-ER injected intra-articularly into the affected knee may be an effective non-opioid treatment option. Although the participants included in this analysis did not fully represent the diverse demographics of active service members, the substantial unmet medical need in the military population suggests that TA-ER may be an important treatment option; additional studies of TA-ER in active military patients are needed., Trial Registration: ClinicalTrials.gov NCT02357459., Funding: Flexion Therapeutics, Inc.

Introduction: Here we examine the relationship between achieving different levels of disease activity with tofacitinib (an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis), long-term structural progression, and patient-reported physical function., Methods: This was a post hoc analysis of two 24-month, phase III randomized controlled trials in methotrexate (MTX)-naïve (ORAL Start [NCT01039688]) or MTX-inadequate responder (IR) patients (ORAL Scan [NCT00847613]) receiving tofacitinib 5 or 10 mg twice daily as either monotherapy or with background MTX. The modified total Sharp score (mTSS) and Health Assessment Questionnaire-Disability Index (HAQ-DI) were analyzed at month 24 according to disease activity at month 6 defined by the Clinical Disease Activity Index (CDAI) or the Disease Activity Score in 28 joints, C-reactive protein (DAS28CRP)., Results: Mean changes from baseline in mTSS at month 24 were less in patients with CDAI remission at month 6 than in those with CDAI moderate/high disease activity (MDA/HDA) at month 6. A DAS28CRP of < 1.9 most closely approximated CDAI remission (≤ 2.8). Tofacitinib appeared to inhibit joint damage in the presence of persistent inflammation compared with MTX. More patients receiving tofacitinib or MTX with CDAI remission or low disease activity (LDA) at month 6 reported normative HAQ-DI scores (< 0.5) at month 24 than did those with CDAI MDA/HDA., Conclusion: Regardless of treatment, in both MTX-naïve and MTX-IR patients, remission or LDA at month 6 was associated with successful long-term outcomes: inhibition of structural progression and normative HAQ-DI scores. Long-term outcomes were similar when patients achieved CDAI remission or a DAS28CRP of < 1.9, confirming that this is an appropriate cut-off for remission with DAS28CRP. Tofacitinib potentially inhibits joint damage even with persistent inflammation., Funding: Pfizer Inc., Trial Registration: Clinicaltrials.gov identifiers: NCT01039688 and NCT00847613.

Introduction: To evaluate the efficacy and safety of secukinumab 150 mg, with or without a loading regimen, using a self-administered prefilled syringe in patients with ankylosing spondylitis (AS) over 104 weeks from the MEASURE 4 study., Methods: Patients (N = 350) with active AS were randomized (1:1:1) to receive subcutaneous secukinumab 150 mg with loading dose (150 mg), without loading dose (150 mg no load), or placebo. All patients received secukinumab or placebo at baseline, weeks 1, 2, and 3 and every 4 weeks starting at week 4. The primary endpoint was the Assessment of SpondyloArthritis international Society criteria for 20% improvement (ASAS20) at week 16., Results: A total of 96.9% of patients (339/350) completed 16 weeks and 82.6% (289/350) completed 104 weeks of treatment. The ASAS20 response rate at week 16 was 59.5% and 61.5% with 150 and 150 mg no load groups, respectively, versus placebo (47%; P = 0.057 and 0.054, respectively); the primary endpoint was not met. Increases in response rates achieved with secukinumab for ASAS20 at week 16 were sustained through week 104. The safety profile of secukinumab 150 mg, with or without a loading regimen, showed no new or unexpected safety signals., Conclusions: Secukinumab 150 mg, with or without loading regimen, provided rapid and sustained decreases in the signs and symptoms of patients with AS, but the differences were not statistically significant at week 16 due to higher than expected placebo responses. The responses and safety profile were consistent with previous phase 3 studies and sustained through 2 years., Trial Registration: ClinicalTrials.gov identifier, NCT02159053., Funding: Novartis Pharma AG, Basel, Switzerland.

Objectives: Secukinumab, a fully human anti-IL-17A monoclonal antibody, provided rapid and sustained improvements in signs and symptoms of ankylosing spondylitis (AS) over 2 years in the Phase 3 MEASURE 1 trial. Here, we report efficacy and safety after 3 years of treatment., Methods: AS subjects completing 2 years of treatment every 4 weeks with subcutaneous secukinumab 150 or 75 mg (following intravenous loading or initial placebo treatment to 16/24 weeks) entered a separate 3-year extension study (NCT01863732). Assessments included ASAS20/40, ASAS5/6, BASDAI, BASDAI 50, BASFI, BASMI, SF-36 physical component summary, ASAS partial remission and ASDAS-CRP. Results were also analysed by prior anti-TNF treatment status., Results: Among 290 subjects completing the core trial, 274 entered the extension study, with 260 subjects (94.9%) completing 156 weeks of treatment. ASAS20/40 response (observed) was 80.2%/61.6% in the IV→150 mg group and 75.5%/50.0% in the IV→75 mg group after 156 weeks. Sustained improvements were also seen in BASDAI, BASFI, BASMI and across all other endpoints regardless of previous exposure to anti-TNF agents. Mean secukinumab exposure was 964.3 days (137.8 weeks). Discontinuation rates were low, and secukinumab had a favourable safety profile, consistent with previous reports. Exposure-adjusted incidence rates for serious infections, Candida infections, Crohn's disease, ulcerative colitis, malignant/unspecified tumours, and adjudicated major adverse cardiac events were 1.1, 0.4, 0.5, 0.1, 0.5 and 0.7 per 100 subject-years, respectively., Conclusions: Secukinumab provided sustained efficacy in signs, symptoms and physical function in subjects with AS over 3 years. No new safety signals were observed.

Objective: To assess prevention of bone mineral density (BMD) loss and durability of the response during treatment with prasterone in women with systemic lupus erythematosus (SLE) receiving chronic glucocorticoids., Methods: 155 patients with SLE received 200 mg/day prasterone or placebo for 6 months in a double-blind phase. Subsequently, 114 patients were re-randomized to receive 200 or 100 mg/day prasterone for 12 months in an open-label phase. Primary efficacy endpoints were changes in BMD at the lumbar spine (L-spine) from baseline to Month 6 and maintenance of BMD from Month 6 to 18 for patients who received prasterone during the double-blind phase., Results: In the double-blind phase, there was a trend for a small gain in BMD at the L-spine for patients who received 200 mg/day prasterone for 6 months versus a loss in the placebo group (mean +/- SD, 0.003 +/- 0.035 vs -0.005 +/- 0.053 g/cm(2), respectively; p = 0.293 between groups). In the open-label phase, there was dose-dependent increase in BMD at the L-spine at Month 18 between patients who received 200 versus 100 mg/day prasterone (p = 0.021). For patients who received 200 mg/day prasterone for 18 months, the L-spine BMD gain was 1.083 +/- 0.512% (p = 0.042). There was no overall change in BMD at the total hip over 18 months with 200 mg/day prasterone treatment. The safety profile reflected the weak androgenic properties of prasterone., Conclusion: This study suggests prasterone 200 mg/day may offer mild protection against bone loss in women with SLE receiving glucocorticoids.

Objective: To demonstrate the safety and efficacy of adalimumab for the treatment of active psoriatic arthritis (PsA) in patients with an inadequate response to disease modifying antirheumatic drugs (DMARD)., Methods: In a placebo controlled, double-blind, randomized, multicenter study, patients were treated for 12 weeks with subcutaneous injections of adalimumab 40 mg every other week (eow) or placebo, followed by a period of open-label treatment with adalimumab 40 mg eow. The primary efficacy endpoint was the percentage of patients who met the American College of Rheumatology (ACR20) core criteria at Week 12. Secondary efficacy measures included the modified Psoriatic Arthritis Response Criteria (PsARC) and assessments of disability, psoriatic lesions, and quality of life. For missing data, nonresponder imputation was used for ACR and PsARC scores and last observation carried forward for other measures., Results: A total of 100 patients received study drug (51 adalimumab, 49 placebo). At Week 12, an ACR20 response was achieved by 39% of adalimumab patients versus 16% of placebo patients (p = 0.012), and a PsARC response was achieved by 51% with adalimumab versus 24% with placebo (p = 0.007). At Week 12, measures of skin lesions and disability were statistically significantly improved with adalimumab. After Week 12, open-label adalimumab provided continued improvement for adalimumab patients and initiated rapid improvement for placebo patients, with ACR20 response rates of 65% and 57%, respectively, observed at Week 24. Serious adverse events had similar frequencies during therapy with placebo (4.1%), blinded adalimumab (2.0%), and open-label adalimumab (3.1%). No serious infections occurred during adalimumab therapy., Conclusion: In this study of patients who had active PsA and a previous, inadequate response to DMARD therapy, adalimumab was well tolerated and significantly reduced the signs, symptoms, and disability of PsA during 12 weeks of blinded and 12 weeks of open-label therapy. Adalimumab also improved psoriasis in these patients.

Objective: This study compared the immunogenicity of influenza and pneumococcal vaccines in adult patients with rheumatoid arthritis (RA) receiving adalimumab or placebo., Methods: In this double-blind, randomized, multicenter study, patients received adalimumab or placebo on Days 1, 15, and 29. Pneumococcal and influenza vaccines were administered on Day 8 (vaccine baseline). Vaccine response (> or = 2-fold titer increase from baseline in > or = 3 of 5 pneumococcal antigens and > or = 4-fold titer increase from baseline in > or = 2 of 3 influenza antigens) and protective antibody titers (> or = 1.6 microg/ml pneumococcal antibody concentration to > or = 3 of 5 antigens and > or = 1:40 influenza antibody titer to > or = 2 of 3 antigens) were analyzed 4 weeks' postvaccination., Results: Following pneumococcal vaccination, percentages of patients achieving a vaccine response were similar in the adalimumab and placebo groups [37.4% and 40.4%, respectively; 95% CI (confidence interval) -16.2%, 10.3%]. Percentages of patients with protective antibody titers were similar in both treatment groups (adalimumab: 85.9%, placebo: 81.7%). Following influenza vaccination, percentages of patients achieving a vaccine response were lower with adalimumab than placebo (51.5% and 63.3%, respectively; 95% CI -25.2%, 1.6%)--a result explained by the subgroup of patients with preexisting protective antibody titers at baseline. For patients without protective antibody titers at baseline, response rates were similar in the 2 groups (adalimumab: 73.3%, placebo: 73.9%). Percentages of patients with protective antibody titers were similar in both treatment groups (adalimumab: 98%, placebo: 94.5%)., Conclusion: Patients with RA treated with adalimumab can be effectively and safely immunized with pneumococcal and influenza vaccines.

Objective: Clinical and radiographic responses were evaluated in patients with psoriatic arthritis (PsA) treated for up to 2 years with etanercept., Methods: Patients were previously randomized to receive placebo or etanercept in a double-blind study and chose to participate in the current open-label extension phase. All patients received etanercept 25 mg twice weekly. Radiographic progression was determined at baseline, 1 year, and 2 years using the Sharp method modified to include joints frequently affected in PsA. Arthritis and psoriasis responses were determined using American College of Rheumatology 20% (ACR20) improvement criteria, PsA response criteria (PsARC), and the psoriasis area severity index (PASI)., Results: Of 205 patients randomized, 169 entered open-label, and 141 [71 randomized to receive placebo (placebo/etanercept) and 70 randomized to receive etanercept (etanercept/etanercept)] had radiographic data available for analysis at 2 years. ACR20 criteria, PsARC, and PASI 50 criteria were met by 64%, 84%, and 62%, respectively, of etanercept/etanercept patients at the end of the 48-week open-label period. Placebo/etanercept patients achieved comparable results within 12 weeks that were sustained at 48 weeks (63%, 80%, and 73%). Radiographic progression was inhibited in the etanercept/ etanercept patients (mean adjusted change in total Sharp score of -0.38 from baseline to 2 yrs). In placebo/etanercept patients, disease progression was inhibited once patients began receiving etanercept (mean adjusted change of -0.22 from 1 year to 2 years). Adverse event rates were similar to those observed during randomized phase, with only one serious adverse event deemed possibly related to etanercept., Conclusion: These data demonstrate a sustained benefit of etanercept treatment, including inhibition of radiographic progression, in patients with PsA.

Objective: To evaluate the efficacy and safety of a selective inhibitor of secretory phospholipase (sPLA2), LY333013, in the treatment of rheumatoid arthritis (RA)., Methods: Two hundred and fifty-one patients with active RA despite treatment with one or more disease modifying antirheumatic drugs (DMARD) received oral doses of LY333013 (50, 250, and 1000 mg) or placebo once daily for 12 weeks. Concomitant low-dose glucocorticoids (< or = 10 mg/day prednisone equivalent) were allowed. Clinical improvement was assessed using the response criteria of the American College of Rheumatology (ACR20), and safety was evaluated with respect to adverse events and laboratory test abnormalities., Results: The demographic characteristics of the treatment groups were similar. Dose-response relationships were found for ACR20 responses (p = 0.058) and reductions in C-reactive protein (p = 0.058) at week 1. The proportions of patients with an ACR20 response subsequently increased in all study groups including the placebo group at weeks 4 and 8, and the initial treatment benefit was lost. Adverse events were generally mild in severity and not associated with treatment., Conclusion: Treatment with LY333013 for 12 weeks was well tolerated but ineffective as an adjunct to DMARD treatment of active RA.

Postmenopausal osteoporosis is associated with significant morbidity, mortality, reduction in quality of life, and increasing health care costs. It is estimated that 1.5 million women in the United States have one or more osteoporosis-related fractures annually. Fractures may occur at any site, but vertebral fractures are the most common. Longitudinal studies have demonstrated a decreased life expectancy associated with both vertebral and nonvertebral fractures. Once an initial fracture occurs, there is a fivefold increased risk of a second fracture within 1 year. The management of osteoporosis today incorporates multiple modalities of therapy. In addition to early detection, patient education, exercise, and nutritional supplementation, multiple therapeutic agents should be implemented early in an attempt to prevent initial and subsequent fractures. This article reviews currently approved modalities of therapy for the prevention and treatment of postmenopausal osteoporosis.
