Impact of hyperuricaemia on patients with psoriatic arthritis treated with secukinumab in the FUTURE 2-5 and MAXIMISE studies.

OBJECTIVES: Patients with psoriatic arthritis (PsA) are at a significantly increased risk of hyperuricaemia and development of gout, and those with hyperuricaemia have been found to respond poorly to PsA treatment and have more peripheral and destructive joint damage. We present a comprehensive post hoc analysis using pooled data from the FUTURE 2-5 studies and the MAXIMISE study to further evaluate the impact of hyperuricaemia on clinical presentation/disease severity and response to secukinumab in patients with PsA. METHODS: Patients were stratified into two groups based on baseline serum uric acid (SUA) level (threshold of 360 µmol/L). A sensitivity analysis was also performed based on SUA thresholds of 300 µmol/L and 420 µmol/L. Demographics, clinical, radiological characteristics and comorbidities data were collected. RESULTS: At baseline, patients with hyperuricaemia were mostly male, reported a higher prevalence of hypertension, with more clinical dactylitis, more psoriasis and more severe skin disease compared with patients with normouricaemia. A similar proportion of patients in the normouricaemic and hyperuricaemic cohorts achieved American College of Rheumatology responses, resolution of enthesitis and dactylitis, inhibition of structural damage progression and improvement in health-related quality of life across all secukinumab doses at week 52. CONCLUSION: Patients with PsA and hyperuricaemia have different clinical characteristics from patients with PsA and normouricaemia. Identification of these patients at an early stage may facilitate a personalised treatment approach and improved management of comorbidities. Furthermore, secukinumab provided a rapid and sustained response across all manifestations of PsA up to week 52, irrespective of baseline uricaemia status.

Effects of secukinumab on synovitis and enthesitis in patients with psoriatic arthritis: 52-week clinical and ultrasound results from the randomised, double-blind ULTIMATE trial with open label extension.

OBJECTIVES: In the ULTIMATE study with an open label extension, we assessed the long-term effect of secukinumab at tissue level on synovitis and enthesitis, and across all psoriatic arthritis (PsA) manifestations, using both clinical evaluations and power Doppler ultrasonography (PDUS). METHODS: This randomised, placebo-controlled, Phase 3 study (ULTIMATE) included biologic-naïve patients with PsA with active PDUS synovitis and clinical enthesitis, and inadequate response to conventional synthetic disease-modifying antirheumatic drugs. The study consisted of 3 treatment periods; in the first period (baseline to week 12) patients were randomised to receive subcutaneous secukinumab (150 mg or 300 mg according to severity of skin psoriasis) or placebo every week until week 4 and once every 4 weeks up to week 12. In the second period (weeks 12-24) all patients received open-label secukinumab with placebo patients switching to secukinumab (150 mg or 300 mg). The third period (weeks 24-52) was an extended open-label treatment period. The long-term responsiveness of the Global EULAR-OMERACT Synovitis Score (GLOESS), clinical enthesitis and global PDUS-detected enthesitis score (using two candidate definitions of activity) at patient level, together with clinical efficacy across key manifestations of PsA and safety were assessed. RESULTS: Of the 166 patients enrolled, 144 completed week 52. A significant reduction in GLOESS was demonstrated in the secukinumab group vs placebo at week 12, followed by a stable reduction of synovitis until week 52 in the secukinumab group while placebo switchers from week 12 reached a similar level of reduction at week 24 with stability thereafter. Likewise, a significant reduction in the Spondyloarthritis Research Consortium of Canada (SPARCC) enthesitis index was shown in the secukinumab group vs placebo at week 12 with sustained improvement to week 52. Global OMERACT PDUS enthesitis scores were numerically lower in secukinumab vs placebo switchers in the first two treatment periods, with some stability in the third period in both groups. Improvements in clinical responses were also observed across all key domains of PsA up to week 52 in both treatment groups with no new or unexpected safety signals. CONCLUSIONS: ULTIMATE showed consistent improvements in clinically and ultrasound-assessed synovitis and enthesitis and sustained clinical efficacy through week 52 in patients with PsA treated with secukinumab and placebo switched to secukinumab.

Secukinumab improves physical function and quality of life and inhibits structural damage in patients with PsA with sustained remission or low disease activity: results from the 2-year phase 3 FUTURE 5 study.

OBJECTIVE: To investigate the impact of sustained low disease activity (LDA)/remission (REM) on physical function, quality of life (QoL) and structural outcomes in secukinumab-treated psoriatic arthritis (PsA) patients from the FUTURE 5 study. METHODS: FUTURE 5 was a randomised, double-blind, placebo-controlled, parallel-group, phase 3 study in patients with active PsA. Patients were categorised according to LDA (Minimal Disease Activity, MDA/Disease Activity index for Psoriatic Arthritis, DAPSA LDA+REM) or REM (very LDA/DAPSA REM): not achieving LDA/REM, achieving it once or sustained LDA/REM ≥3 times up to week 104. Key outcomes were improvements in Health Assessment Questionnaire Disability Index and Short Form-36 Physical Component Summary Score, proportion of non-radiographic progressors and predictors of sustained LDA response. RESULTS: Patients were randomised (N=996) into the following treatment groups: secukinumab 300 mg (N=222), secukinumab 150 mg loading (N=220)/non-loading (N=222) and placebo (N=332). Baseline characteristics were comparable between patients with sustained DAPSA and MDA responses. By week 104, 48%-81% and 19%-36% of the secukinumab-treated patients achieved sustained LDA and REM, respectively. Numerically greater improvements in physical function and QoL were observed with sustained LDA/REM versus LDA/REM achieved once or not at all, although patients reached the established minimal clinically important difference for all composite indices. A high proportion of secukinumab-treated patients were non-structural progressors at 2 years irrespective of achieving sustained LDA/REM. Younger age, lower body mass index at baseline, reduced tender joint count and PsA pain at week 16 were key predictors of sustained LDA in secukinumab-treated patients. CONCLUSION: Sustained LDA/REM was associated with improvements in physical function, QoL and inhibition of structural damage progression.

Long-term Safety of Secukinumab Over Five Years in Patients with Moderate-to-severe Plaque Psoriasis, Psoriatic Arthritis and Ankylosing Spondylitis: Update on Integrated Pooled Clinical Trial and Post-marketing Surveillance Data.

Secukinumab, a selective interleukin (IL)-17A inhibitor, is approved for use in adult and paediatric psoriasis, psoriatic arthritis, ankylosing spondylitis and non-radiographic axial spondyloarthritis. The aim of this study was to report the long-term safety of secukinumab in pooled data from 28 clinical trials and a post-marketing safety surveillance in psoriasis, psoriatic arthritis and ankylosing spondylitis patients. Analyses included 12,637 secukinumab-treated patients, corresponding to 15,063, 5,985 and 3,527 patient-years of exposure in psoriasis, psoriatic arthritis and ankylosing spondylitis patients, respectively. Incidences of serious adverse events were low, with no identifiable patterns across indications. Active tuberculosis or latent tuberculosis infections were rare. The incidence of opportunistic infections was < 0.2/100 patient-years, the incidence of malignancy was ≤ 1/100 patient-years, and the incidence of major adverse cardiovascular events was < 0.7/100 patient-years, with no apparent increases over time. Secukinumab demonstrated a favourable safety profile for up to 5 years of treatment across the 3 indications, and no new safety signals were identified.

A Pooled Analysis Reporting the Efficacy and Safety of Secukinumab in Male and Female Patients with Ankylosing Spondylitis.

INTRODUCTION: Despite of higher disease burden, lower efficacy to biologics has been reported in female compared to male patients with ankylosing spondylitis (AS). The aim of this study was to evaluate the efficacy and safety of secukinumab by sex in patients with active AS from five phase 3 studies (MEASURE 1-5) through 52 weeks. METHODS: Baseline demographics, disease characteristics and efficacy outcomes at Weeks 16 and 52 were summarized for males versus females. Baseline predictor analysis used multivariable logistic regression for binary outcome measures or generalized linear model for continuous outcome measures to assess the impact of sex as one of the independent variables on selected efficacy outcomes at Week 52. RESULTS: Overall, 1031 males and 396 females were included in this analysis. Smoking status, hs-CRP, prior exposure to TNF inhibitors, BASMI occiput-to-wall and tragus-to-wall distance (cm) were higher in males, whereas MASES was higher in females. Efficacy outcomes i.e., ASAS40 responses and BASDAI change from baseline at Weeks 16 and 52 were generally comparable between males and females. Response rates were found to be significantly higher in male patients when compared with female patients only for ASDAS-CRP inactive disease (ID) at Week 52. CONCLUSION: Comparable efficacy and safety outcomes were observed between male and female patients with active AS treated with secukinumab over 52 weeks. Further, sex was not an independent predictor of treatment response to secukinumab as assessed by ASAS40 responder rates and BASDAI change from baseline; association of ASDAS-CRP ID responder rates with sex warrants further exploration.

Association of Secukinumab Treatment With Tuberculosis Reactivation in Patients With Psoriasis, Psoriatic Arthritis, or Ankylosing Spondylitis.

Importance: Approximately one-quarter of the global population have latent tuberculosis infection (LTBI), and tuberculosis (TB) is accountable for more than 1.5 million deaths annually. Methotrexate, cyclosporine, and tumor necrosis factor inhibitors may be associated with increased risk of TB and LTBI reactivation, although data are limited on the risks of TB with use of newer biologics. Objective: To assess the association of secukinumab with reporting of active TB development, TB reactivation, and LTBI activation as an adverse event (AE) in patients with psoriasis, psoriatic arthritis, or ankylosing spondylitis. Design, Setting, and Participants: This pooled cohort study pooled data from 28 clinical trials of secukinumab used in psoriasis (17 phase 3 or 3b and 2 phase 4 trials), psoriatic arthritis (5 phase 3 trials), and ankylosing spondylitis (4 phase 3 trials). A search of the Novartis Secukinumab Compound Pool Database was conducted for the 28 trials. All trial participants who had received at least 1 approved subcutaneous dose of secukinumab (150 mg or 300 mg) were included. Before randomization in these trials, patients underwent screening for TB. Patients with active TB were excluded, and patients with LTBI were treated according to local guidelines. Data were analyzed from the start of treatment in the individual studies through December 25, 2018. Main Outcomes and Measures: Reporting of active TB or LTBI as an AE over a 5-year period using exposure-adjusted incidence rates (EAIR; incidence rates per 100 patient-years). Results: A total of 12 319 patients were included, of whom 8819 patients had psoriasis (71.6%; 5930 men [67.2%]; mean [SD] age, of 44.9 [13.5] years), 2523 had psoriatic arthritis (20.5%; 1323 women [52.4%]; mean [SD] age, 48.8 [12.1] years), and 977 had ankylosing spondylitis (7.3%; 658 men [67.3%]; mean [SD] age, 42.3 [11.9] years). In the total population, 684 patients (5.6%) had tested positive for LTBI at screening. Over 5 years, LTBI as an AE during secukinumab treatment was reported in 13 patients (0.1% of 12 319). Of these 13 patients, 6 had a prior positive LTBI test result, and 7 were newly diagnosed as having LTBI. Four of the 7 patients had psoriasis (EAIR, 0.03; 95% CI, 0.01-0.07), 1 had psoriatic arthritis (EAIR, 0.02; 95% CI, 0.00-0.11), and 2 had ankylosing spondylitis (EAIR, 0.08; 95% CI, 0.01-0.28). No cases of active TB were reported. Conclusions and Relevance: This study found that LTBI reported as an AE after secukinumab treatment was uncommon and appeared to support the use of secukinumab in chronic systemic inflammatory conditions.

Initiation of sacubitril/valsartan in haemodynamically stabilised heart failure patients in hospital or early after discharge: primary results of the randomised TRANSITION study.

AIMS: To assess tolerability and optimal time point for initiation of sacubitril/valsartan in patients stabilised after acute heart failure (AHF). METHODS AND RESULTS: TRANSITION was a randomised, multicentre, open-label study comparing two treatment initiation modalities of sacubitril/valsartan. Patients aged ≥ 18 years, hospitalised for AHF were stratified according to pre-admission use of renin-angiotensin-aldosterone system inhibitors and randomised (n = 1002) after stabilisation to initiate sacubitril/valsartan either ≥ 12-h pre-discharge or between Days 1-14 post-discharge. Starting dose (as per label) was 24/26 mg or 49/51 mg bid with up- or down-titration based on tolerability. The primary endpoint was the proportion of patients attaining 97/103 mg bid target dose after 10 weeks. Median time of first dose of sacubitril/valsartan from the day of discharge was Day -1 and Day +1 in the pre-discharge group and the post-discharge group, respectively. Comparable proportions of patients in the pre- and post-discharge initiation groups met the primary endpoint [45.4% vs. 50.7%; risk ratio (RR) 0.90; 95% confidence interval (CI) 0.79-1.02]. The proportion of patients who achieved and maintained for ≥ 2 weeks leading to Week 10, either 49/51 or 97/103 mg bid was 62.1% vs. 68.5% (RR 0.91; 95% CI 0.83-0.99); or any dose was 86.0% vs. 89.6% (RR 0.96; 95% CI 0.92-1.01). Discontinuation due to adverse events occurred in 7.3% vs. 4.9% of patients (RR 1.49; 95% CI 0.90-2.46). CONCLUSIONS: Initiation of sacubitril/valsartan in a wide range of heart failure with reduced ejection fraction patients stabilised after an AHF event, either in hospital or shortly after discharge, is feasible with about half of the patients achieving target dose within 10 weeks.

Long-Term Telbivudine Treatment Results in Resolution of Liver Inflammation and Fibrosis in Patients with Chronic Hepatitis B.

INTRODUCTION: The long-term goal of chronic hepatitis B (CHB) treatment is improvement of liver disease and prevention of cirrhosis. The aim of this study was to assess whether prolonged telbivudine treatment improves liver inflammation and fibrosis. The primary objective was to evaluate the proportion of patients with absence/minimal inflammation (Knodell necroinflammatory score ≤3) on liver biopsy at Year 5. METHODS: Fifty-seven patients aged 16-70 years with a clinical history of CHB and active viral replication (38 hepatitis B e antigen [HBeAg] positive and 19 HBeAg negative) were followed for 6 years: 33 received telbivudine 600 mg/day continuously for 5 years; 24 received lamivudine 100 mg/day for 2 years and then telbivudine for 3 years. Liver biopsies were taken pre-treatment and after 5 years of treatment. RESULTS: At baseline, mean (standard deviation) serum hepatitis B virus (HBV) DNA load was 8.5 (1.7) log10 copies/mL, Knodell necroinflammatory score was 7.6 (2.9), and Ishak fibrosis score was 2.2 (1.1). After antiviral treatment (median duration: 261 weeks), liver histology improved with increased proportions of patients with absence/minimal liver inflammation (Knodell necroinflammatory score ≤3), from 16% (9/57) at baseline to 98% (56/57), and absence/minimal fibrosis (Ishak score ≤1), from 25% (14/57) at baseline to 84% (48/57). At Year 5, HBV DNA load was <300 copies/mL for all patients; cumulative HBeAg loss and seroconversion rates were 88% and 77%, respectively. At Year 6, 95% of patients with abnormal baseline glomerular filtration rate (60-90 mL/min/1.73 m(2)) improved to normal GFR (>90 mL/min/1.73 m(2)). CONCLUSION: Long-term telbivudine treatment with profound and durable viral suppression significantly improved liver histology, thus achieving the long-term goals of CHB treatment. FibroScan(®) results after 5 and 6 years of treatment (in almost 20% of patients) were consistent with this information.

Kinetics of hepatitis B surface antigen decline during 3 years of telbivudine treatment in hepatitis B e antigen-positive patients.

UNLABELLED: The impact of prolonged direct antiviral therapy on hepatitis B surface antigen (HBsAg) levels in patients with chronic hepatitis B is poorly understood. We quantitatively assessed serum HBsAg levels during 3 years of telbivudine treatment, as well as their relationship with virologic and biochemical characteristics in 162 hepatitis B e antigen-positive patients who maintained undetectable serum hepatitis B virus (HBV) DNA long-term. Telbivudine treatment progressively reduced serum HBsAg levels (mean ± SD) from baseline (3.8 ± 0.6 log10 IU/mL) to treatment week 24 (3.4 ± 0.7 log10 IU/mL), treatment year 1 (3.3 ± 0.8 log10 IU/mL), and treatment year 3 (3.0 ± 1.4 log10 IU/mL) (P <0.0001). In this patient population, HBsAg loss was observed in nine (6%) of 162 patients through year 3. During the first year of treatment, three patterns of HBsAg decline were observed: rapid (≥ 1 log10 IU/mL) in 32 patients, slow (0-1 log10 IU/mL) in 74 patients, and steady levels in 56 patients. These findings were associated with different likelihoods of HBsAg loss during long-term telbivudine therapy. Eight of 32 patients with rapid HBsAg decline versus none of 56 patients with steady HBsAg levels achieved HBsAg loss at year 3 (P = 0.0024). HBV genotype was a significant determinant for HBsAg kinetics, with the fastest decline in genotype A patients. In patients with subsequent HBsAg loss, viral antigens were already undetectable in liver biopsy samples after 1 year of treatment. This was associated with markedly enhanced antiviral T cell reactivity. CONCLUSION: In patients who have effective suppression of viral replication during telbivudine treatment, a rapid decline in serum HBsAg levels during the first year may identify those with a greater likelihood of achieving HBsAg clearance.
