RESUMO

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.

RESUMO

BACKGROUND: Secukinumab, a human monoclonal antibody that selectively targets interleukin-17A, is highly efficacious in the treatment of moderate-to-severe psoriasis, starting at early time points, with a sustained effect and a favorable safety profile. METHODS: Patients with moderate-to-severe plaque psoriasis were randomized to secukinumab 300 mg, secukinumab 150 mg, or placebo self-administered by prefilled syringe at baseline, weeks 1, 2, and 3, and then every four weeks from week 4 to 48. Efficacy responses (≥ 75/90/100% improvement in Psoriasis Area and Severity Index [PASI 75/90/100] and clear/almost clear skin by Investigator's Global Assessment 2011 modified version [IGA mod 2011 0/1]) were measured to week 52. Patient-reported usability of the prefilled syringe was evaluated by the Self-Injection Assessment Questionnaire to week 48. RESULTS: The efficacy of secukinumab increased to week 16 and was maintained to week 52. With secukinumab 300 mg at week 52, PASI 75/90/100 and IGA mod 2011 0/1 responses were achieved by 83.5%/68.0%/47.5% and 71.5% of patients when analyzed by multiple imputation, respectively, and by 75.9%/62.1%/43.1% and 63.8% of patients when analyzed by nonresponder imputation, respectively. With secukinumab 150 mg at week 52, PASI 75/90/100 and IGA mod 2011 0/1 responses were achieved by 63.5%/50.3%/31.1% and 43.6% of patients when analyzed by multiple imputation, respectively, and by 61.0%/49.2%/30.5% and 42.4% of patients when analyzed by nonresponder imputation, respectively. Self-reported acceptability of the prefilled syringe was high throughout the study. The incidence of adverse events (AE) was well balanced between groups, with AEs reported in 74.4% of patients receiving secukinumab 300 mg and 77.3% of patients receiving secukinumab 150 mg. Nasopharyngitis was the most common AE across both secukinumab groups. CONCLUSION: Self-administration of secukinumab by prefilled syringe was associated with robust and sustained efficacy and a favorable safety profile up to week 52.

RESUMO

BACKGROUND: Fractures in men are a major health issue, and data on the antifracture efficacy of therapies for osteoporosis in men are limited. We studied the effect of zoledronic acid on fracture risk among men with osteoporosis. METHODS: In this multicenter, double-blind, placebo-controlled trial, we randomly assigned 1199 men with primary or hypogonadism-associated osteoporosis who were 50 to 85 years of age to receive an intravenous infusion of zoledronic acid (5 mg) or placebo at baseline and at 12 months. Participants received daily calcium and vitamin D supplementation. The primary end point was the proportion of participants with one or more new morphometric vertebral fractures over a period of 24 months. RESULTS: The rate of any new morphometric vertebral fracture was 1.6% in the zoledronic acid group and 4.9% in the placebo group over the 24-month period, representing a 67% risk reduction with zoledronic acid (relative risk, 0.33; 95% confidence interval, 0.16 to 0.70; P=0.002). As compared with men who received placebo, men who received zoledronic acid had fewer moderate-to-severe vertebral fractures (P=0.03) and less height loss (P=0.002). Fewer participants who received zoledronic acid had clinical vertebral or nonvertebral fractures, although this difference did not reach significance because of the small number of fractures. Bone mineral density was higher and bone-turnover markers were lower in the men who received zoledronic acid (P<0.05 for both comparisons). Results were similar in men with low serum levels of total testosterone. The zoledronic acid and placebo groups did not differ significantly with respect to the incidence of death (2.6% and 2.9%, respectively) or serious adverse events (25.3% and 25.2%). CONCLUSIONS: Zoledronic acid treatment was associated with a significantly reduced risk of vertebral fracture among men with osteoporosis.

RESUMO

OBJECTIVE: Long-term glucocorticoid use is accompanied by rapid bone loss; however, early treatment with bisphosphonates prevents bone loss and reduces fracture risk. The aim of this study was to examine the effects of two bisphosphonates, i.v. zoledronic acid (ZOL) versus oral risedronate (RIS), on bone turnover markers (BTMs) in subjects with glucocorticoid-induced osteoporosis (GIO). METHODS: Patients were randomly stratified according to the duration of pre-study glucocorticoid therapy [prevention subpopulation (ZOL, n = 144; RIS, n = 144) ≤3 months, treatment subpopulation (ZOL, n = 272; RIS, n = 273) >3 months]. Changes in ß-C-terminal telopeptides of type 1 collagen (ß-CTx), N-terminal telopeptide of type I collagen (NTx), procollagen type 1 N-terminal propeptide (P1NP) and bone-specific alkaline phosphatase (BSAP) from baseline were measured on day 10 and months 3, 6 and 12. RESULTS: At most time points, there were significantly greater reductions (P < 0.05) in the concentrations of serum ß-CTx, P1NP and BSAP and urine NTx in subjects on ZOL compared with RIS in both males and females of the treatment and prevention subpopulations. In pre- and post-menopausal women, there were significantly greater reductions in the concentrations of BTMs with ZOL compared with RIS. At 12 months, ZOL had significantly greater reductions compared with RIS (P < 0.05) for ß-CTx, P1NP, BSAP and NTx levels, independent of glucocorticoid dose. CONCLUSIONS: Once-yearly i.v. infusion of ZOL 5 mg was well tolerated in different subgroups of GIO patients. ZOL was non-inferior to RIS and even superior to RIS in the response of BTMs in GIO patients. TRIAL REGISTRATION: ClinicalTrials.gov, http://clinicaltrials.gov, NCT00100620.

RESUMO

BACKGROUND: Plaque psoriasis affects ~ 1% of the pediatric population, negatively impacting quality of life. The efficacy and safety of secukinumab in pediatric patients with moderate to severe or severe chronic plaque psoriasis have been established in two pivotal phase 3 trials (open-label, NCT03668613; double-blind, NCT02471144). OBJECTIVES: The aims were to report the pooled safety of secukinumab up to 52 weeks from two studies in subgroups of pediatric patients stratified by age and bodyweight, and to present, alongside the pediatric data, the pooled safety data from four pivotal adult secukinumab trials. METHODS: The safety of secukinumab was evaluated in subgroups of pediatric patients defined by age (6 to < 12 and 12 to < 18 years) and bodyweight (< 25 kg, 25 to < 50 kg, and ≥ 50 kg) in the pooled population. Patients received secukinumab low dose (LD; 75/75/150 mg), secukinumab high dose (HD; 75/150/300 mg), placebo, or etanercept (0.8 mg/kg). For safety analyses, data were pooled from the pediatric studies NCT03668613 and NCT02471144, and presented alongside the pooled data from four adult pivotal studies (NCT01365455, NCT01636687, NCT01358578, NCT01555125). RESULTS: A total of 198 pediatric patients (overall exposure: 184.6 patient-years [PY]) and 1989 adult patients (1749.5 PY) receiving secukinumab up to week 52 were included in this analysis. At week 52, the incidence of adverse events (AEs) was lower in the lower age and bodyweight subgroups. The AEs reported within these subgroups were consistent with the overall AEs reported in this analysis. Overall, exposure-adjusted incidence rates for treatment-emergent AEs were lower in the secukinumab-treated pediatric pool (198.8/100 PY) compared with the etanercept (266.3/100 PY) and adult pools (256.1/100 PY). Up to 52 weeks, the incidence rates of the AEs in the secukinumab-treated patients in the 6 to < 12 years subgroup and 12 to < 18 years subgroup were 167.7/100 PY and 214.7/100 PY, respectively. Similarly, incidence rates of the AEs in the secukinumab-treated patients in the < 25 kg, 25 kg to < 50 kg, and ≥ 50 kg subgroups were 177.3/100 PY, 192.5/100 PY, and 206.8/100 PY, respectively. Nasopharyngitis was the most frequently reported AE in secukinumab-treated pediatric patients across age (< 12 years: 11.8/100 PY; ≥ 12 years: 42.4/100 PY) and bodyweight (< 25 kg: 22.8/100 PY; 25 kg to < 50 kg: 19.0/100 PY; ≥ 50 kg: 43.0/100 PY). Of the 198 secukinumab-treated pediatric patients, one reported nail Candida, one reported skin Candida, and two reported vulvovaginal Candida. Transient and mostly mild events of neutropenia were observed with secukinumab, none leading to study treatment discontinuation. No incidence of treatment-emergent anti-drug antibodies was reported in pediatric patients treated with secukinumab. CONCLUSIONS: Secukinumab was well tolerated in pediatric patients with moderate to severe and severe plaque psoriasis across age and bodyweight subgroups. The overall safety profile of secukinumab in pediatric patients was consistent with that of adult patients.

RESUMO

BACKGROUND: The efficacy and safety of biologic treatments for children and adolescents with moderate to severe psoriasis should be examined over a considerable time period and in different subgroups. OBJECTIVE: We report the efficacy and safety of secukinumab low dose (LD) and high dose (HD) regimens in pediatric patients with moderate to severe psoriasis for up to Week 52. METHODS: This was a randomized, open-label, parallel-group, multicenter study in patients aged  6 to < 18 years. Patients were randomized in a 1:1 ratio to receive LD (75/75/150 mg; N = 42) or HD (75/150/300 mg; N = 42) subcutaneous secukinumab. At randomization, patients were stratified by weight (< 25, 25 to < 50, ≥ 50 kg) and disease severity (moderate/severe). The study is ongoing; the present analysis included data up to Week 52 collected from August 29, 2018 (first patient first visit) to May 28, 2020 (last patient last visit for Week 52). Efficacy was measured using Investigator's Global Assessment modified 2011 0/1 (IGA 0/1) and Psoriasis Area Severity Index (PASI) 75/90/100 response. Safety outcomes included assessment of adverse events. RESULTS: Of the 84 enrolled patients, 78 (92.9%) completed 52 weeks of treatment. Overall, response rates for PASI 75 and IGA 0/1 were similar between the LD (92.8/88.9%) and HD (93.3/84.7%) groups at Week 52. In the LD and HD groups, PASI 90/100 responses at Week 52 were 78.7/53.5% and 84.7/70.0%, respectively. The proportions of IGA 0/1 and PASI 75/90 responders were comparable for the age, body weight, and disease severity subgroups in the secukinumab LD and HD groups. Mean absolute PASI change from baseline at week 52 was - 17.3 ± standard deviation 5.0 and - 18.2 ± 7.0, a percentage change of - 94.3 and - 94.5% for the LD and HD groups, respectively. More than 70% of evaluable patients achieved Children's Dermatology Life Quality Index 0/1 at Week 52 (LD 70.7%; HD 70.3%). The safety profile was consistent with that in adults, with no new safety signals for either secukinumab dosing regimen. CONCLUSION: A high proportion of pediatric patients with psoriasis responded to both dosing regimens of secukinumab and maintained clinical responses through 52 weeks of treatment. No clinical difference was observed in the efficacy of secukinumab across the pediatric subgroups. Safety events were consistent with the established safety profile of secukinumab. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03668613.

RESUMO

BACKGROUND: Persistent use of glucocorticoid drugs is associated with bone loss and increased fracture risk. Concurrent oral bisphosphonates increase bone mineral density and reduce frequency of vertebral fractures, but are associated with poor compliance and adherence. We aimed to assess whether one intravenous infusion of zoledronic acid was non-inferior to daily oral risedronate for prevention and treatment of glucocorticoid-induced osteoporosis. METHODS: This 1-year randomised, double-blind, double-dummy, non-inferiority study of 54 centres in 12 European countries, Australia, Hong Kong, Israel, and the USA, tested the effectiveness of 5 mg intravenous infusion of zoledronic acid versus 5 mg oral risedronate for prevention and treatment of glucocorticoid-induced osteoporosis. 833 patients were randomised 1:1 to receive zoledronic acid (n=416) or risedronate (n=417). Patients were stratified by sex, and allocated to prevention or treatment subgroups dependent on duration of glucocorticoid use immediately preceding the study. The treatment subgroup consisted of those treated for more than 3 months (272 patients on zoledronic acid and 273 on risedronate), and the prevention subgroup of those treated for less than 3 months (144 patients on each drug). 62 patients did not complete the study because of adverse events, withdrawal of consent, loss to follow-up, death, misrandomisation, or protocol deviation. The primary endpoint was percentage change from baseline in lumbar spine bone mineral density. Drug efficacy was assessed on a modified intention-to-treat basis and safety was assessed on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, number NCT00100620. FINDINGS: Zoledronic acid was non-inferior and superior to risedronate for increase of lumbar spine bone mineral density in both the treatment (least-squares mean 4.06% [SE 0.28] vs 2.71% [SE 0.28], mean difference 1.36% [95% CI 0.67-2.05], p=0.0001) and prevention (2.60% [0.45] vs 0.64% [0.46], 1.96% [1.04-2.88], p<0.0001) subgroups at 12 months. Adverse events were more frequent in patients given zoledronic acid than in those on risedronate, largely as a result of transient symptoms during the first 3 days after infusion. Serious adverse events were worsening rheumatoid arthritis for the treatment subgroup and pyrexia for the prevention subgroup. INTERPRETATION: A single 5 mg intravenous infusion of zoledronic acid is non-inferior, possibly more effective, and more acceptable to patients than is 5 mg of oral risedronate daily for prevention and treatment of bone loss that is associated with glucocorticoid use.

RESUMO

Clinical data suggest concomitant therapy with bisphosphonates and parathyroid hormone (PTH) may blunt the anabolic effect of PTH; rodent models suggest that infrequently administered bisphosphonates may interact differently. To evaluate the effects of combination therapy with an intravenous infusion of zoledronic acid 5 mg and daily subcutaneous recombinant human (rh)PTH(1-34) (teriparatide) 20 µg versus either agent alone on bone mineral density (BMD) and bone turnover markers, we conducted a 1-year multicenter, multinational, randomized, partial double-blinded, controlled trial. 412 postmenopausal women with osteoporosis (mean age 65 ± 9 years) were randomized to a single infusion of zoledronic acid 5 mg plus daily subcutaneous teriparatide 20 µg (n = 137), zoledronic acid alone (n = 137), or teriparatide alone (n = 138). The primary endpoint was percentage increase in lumbar spine BMD (assessed by dual-energy X-ray absorptiometry [DXA]) at 52 weeks versus baseline. Secondary endpoints included change in BMD at the spine at earlier time points and at the total hip, trochanter, and femoral neck at all time points. At week 52, lumbar spine BMD had increased 7.5%, 7.0%, and 4.4% in the combination, teriparatide, and zoledronic acid groups, respectively (p < .001 for combination and teriparatide versus zoledronic acid). In the combination group, spine BMD increased more rapidly than with either agent alone (p < .001 versus both teriparatide and zoledronic acid at 13 and 26 weeks). Combination therapy increased total-hip BMD more than teriparatide alone at all times (all p < .01) and more than zoledronic acid at 13 weeks (p < .05), with final 52-week increments of 2.3%, 1.1%, and 2.2% in the combination, teriparatide, and zoledronic acid groups, respectively. With combination therapy, bone formation (assessed by serum N-terminal propeptide of type I collagen [PINP]) increased from 0 to 4 weeks, declined minimally from 4 to 8 weeks, and then rose throughout the trial, with levels above baseline from 6 to 12 months. Bone resorption (assessed by serum ß-C-telopeptide of type I collagen [ß-CTX]) was markedly reduced with combination therapy from 0 to 8 weeks (a reduction of similar magnitude to that seen with zoledronic acid alone), followed by a gradual increase after week 8, with levels remaining above baseline for the latter half of the year. Levels for both markers were significantly lower with combination therapy versus teriparatide alone (p < .002). Limitations of the study included its short duration, lack of endpoints beyond DXA-based BMD (e.g., quantitative computed tomography and finite-element modeling for bone strength), lack of teriparatide placebo, and insufficient power for fracture outcomes. We conclude that while teriparatide increases spine BMD more than zoledronic acid and zoledronic acid increases hip BMD more than teriparatide, combination therapy provides the largest, most rapid increments when both spine and hip sites are considered.

RESUMO

OBJECTIVE: Bisphosphonates inhibit osteoclast activity, which is central to the development of bone damage in rheumatoid arthritis (RA). The aim of this study was to assess whether treatment with zoledronic acid, compared with placebo, could achieve a > or = 50% reduction in the development of new erosions on magnetic resonance imaging (MRI) in patients with early RA. METHODS: In this proof-of-concept study, 39 patients with early RA and clinical synovitis of the hand/wrist were randomized to receive infusions with either zoledronic acid (5 mg) or placebo, administered at baseline and week 13. Patients in both groups received methotrexate (MTX) at a dosage of 7.5-20 mg/week. MRI and plain radiography were performed at baseline and week 26. RESULTS: At week 26, the mean +/- SD change in MRI hand and wrist erosions was 61% lower in the zoledronic acid group compared with the placebo group (0.9 +/- 1.63 versus 2.3 +/- 3.09; P = 0.176). The mean +/- SD increase in the number of hand and wrist bones with erosions was 0.3 +/- 0.75 for zoledronic acid compared with 1.4 +/- 1.77 for placebo (P = 0.029). The proportion of patients in whom new MRI-visualized bone edema developed was smaller in the zoledronic acid group compared with the placebo group (33% versus 58%; P = 0.121). The zoledronic acid group had a mean change in the number of radiographic erosions of 0.1 compared with 0.5 for the placebo group (P = 0.677). The safety profile of zoledronic acid was similar to that of placebo. CONCLUSION: The results of this study suggest a structural benefit associated with zoledronic acid therapy in patients with RA, as demonstrated by consistent results in structural end points in favor of zoledronic acid plus MTX compared with MTX alone.
