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.
Previous clinical trials have not evaluated improvement in nail psoriasis as a primary end point.
This phase 3 trial evaluated the safety and efficacy of adalimumab in patients with ...moderate-to-severe fingernail psoriasis and moderate-to-severe plaque psoriasis.
Patients were randomized 1:1 to 40 mg adalimumab every other week or placebo. The primary efficacy end point was at least 75% improvement in total-fingernail modified Nail Psoriasis Severity Index (NAPSI75) response rate at week 26. Ranked secondary end point scores evaluated at week 26 were total-fingernail NAPSI and modified NAPSI, nail pain, Nail Psoriasis Physical Functioning Severity, Brigham Scalp Nail Inverse Palmo-Plantar Psoriasis Index, and Physician's Global Assessment (fingernail psoriasis).
Of the 217 randomized patients (108 received placebo and 109 received adalimumab), 188 (86.6%) completed 26 weeks of treatment (period A) or escaped early to the open-label period. The study met the primary end point (response rate of 3.4% with placebo vs 46.6% with adalimumab P < .001) and all ranked secondary end points. The serious adverse event rates (placebo vs adalimumab) in period A were 4.6% versus 7.3%; the serious infections rates were 1.9% versus 3.7%.
Patients with less than 5% BSA involvement were not eligible for enrollment.
After 26 weeks of adalimumab treatment, significant improvements were seen in the primary and all ranked secondary end points and in signs and symptoms of moderate-to-severe nail psoriasis versus with placebo and no new safety risks were identified.
Background: Terbinafine is an established drug for the treatment of toenail onychomycosis. Minimizing the total dose of terbinafine and giving it intermittently could improve tolerability as well as ...compliance, provided efficacy is not compromised. Objective: Two identical trials were conducted to compare the efficacy, safety and tolerability of the current standard regimen of terbinafine 250 mg daily with a new formulation of terbinafine given intermittently for three cycles of 2 weeks of treatment (350 mg daily) followed by 2 weeks off treatment. Methods: A total of 2005 patients with a clinical diagnosis of subungual onychomycosis of the large toenail confirmed by microscopy and culture for a dermatophyte were recruited into the two trials and treated for 12 weeks. Results: Patients with onychomycosis of prolonged duration (mean 9 years) and a median nail involvement of 63% with or without spikes, lateral involvement and white superficial onychomycosis (WSO) were included in the trial. The studies found a significant difference (p<0.05) in favour of standard daily dosing with terbinafine. Response rates for the primary variable complete cure (mycological and clinical cure) were lower with the new formulation in both Trial I (−5.8%; 95% CI −11.8, 0.07) and Trial II (difference −5.9%; 95% CI −12, 0.1). Both treatments were equally well tolerated, with approximately 11% of patients in both groups reporting at least one treatment-related adverse event. Conclusions: Pulsed dosing with terbinafine did not provide any clear safety advantages and was significantly less effective. Consequently, continuous treatment with terbinafine tablets remains the optimal therapy for onychomycosis.
