Safety and efficacy of adalimumab treatment in Japanese patients with psoriasis: Results of SALSA study.

ABSTRACT: The safety and efficacy of adalimumab were evaluated over 24 weeks in Japanese patients with psoriasis in routine clinical practice. In this multicenter, observational, open-label, postmarketing study, primary efficacy measures included the Psoriasis Area and Severity Index (PASI) and the Dermatology Life Quality Index (DLQI) in all patients with psoriasis. In patients with psoriatic arthritis (PsA), the 28-joint Disease Activity Score (DAS28) and the visual analog scale (VAS) pain were also evaluated. Safety was assessed based on the frequency of adverse drug reactions (ADR). Among patients with psoriasis evaluated for efficacy (n = 604), significant improvements from baseline were observed in mean PASI and DLQI scores at weeks 16 and 24 (all P < 0.0001). Furthermore, in psoriasis patients without PsA, the PASI 75/90 response rates were 55.9%/28.4% at week 16 (n = 306) and 65.6%/43.3% at week 24 (n = 270), respectively. In patients with PsA evaluable for effectiveness, significant improvements from baseline were observed in PASI, DAS28 erythrocyte sedimentation rate, DAS28 C-reactive protein and VAS pain at weeks 16 and 24 (all P < 0.0001). ADR and serious ADR were reported by 26.1% and 3.3%, respectively, of 731 safety evaluable patients with psoriasis; no unexpected safety findings were noted. The safety profile and effectiveness of adalimumab for the treatment of psoriasis in a routine clinical setting were as expected in Japanese patients.

Project description:BackgroundThis phase 3 trial is the first to evaluate the efficacy and safety of treatment with the systemic TNF-α inhibitor, adalimumab, for Chinese patients with moderate-to-severe plaque psoriasis.MethodsIn the 12-week, double-blind, placebo-controlled Period A, patients were randomized 4 : 1 to receive adalimumab 40 mg every-other-week (following a single 80 mg dose), or placebo every-other-week. In the subsequent 12-week, open-label, Period B, all patients received adalimumab 40 mg every-other-week starting at week 13, following a single, blinded dose at week 12 of adalimumab 80 mg or matching placebo (for patients receiving placebo or adalimumab in Period A respectively). In Period A, efficacy was analysed for all randomized patients and safety for all patients receiving ≥1 dose of the study drug.ResultsFor the 425 patients in this study (87 placebo; 338 adalimumab), a higher percentage randomized to adalimumab achieved the primary endpoint of ≥75% improvement from baseline in PASI score (PASI 75) at week 12: placebo 11.5% (10/87); adalimumab 77.8% (263/338; P < 0.001). Physician's Global Assessment of clear to minimal was achieved at week 12 by 14.9% placebo (13/87) and 80.5% adalimumab (272/338; P < 0.001). For patients who received adalimumab at any time during the study (All-adalimumab Population), treatment-emergent adverse events (AEs) were reported by 63.4%; the most common was upper respiratory infection (16.1%). Serious AEs were reported by 3.5% of the All-adalimumab Population, and serious infectious AEs by 1.2%, which include lung infection, pneumonia and tuberculosis [2 (0.5%) patients each]. There was one death (chronic heart failure).ConclusionIn these Chinese patients with moderate-to-severe psoriasis, a significantly greater percentage treated with adalimumab compared with placebo achieved efficacy endpoints at week 12 and efficacy was sustained to week 24. Safety results were consistent with the known adalimumab safety profile; no new safety signals were identified in the 24 weeks of treatment.

Project description:IntroductionCertolizumab pegol (CZP), an Fc-free, PEGylated anti-tumour necrosis factor biologic, dosed at 400 mg every 2 weeks (Q2W) and 200 mg Q2W over 16 weeks, resulted in improvements in Japanese patients with moderate to severe plaque psoriasis (PSO); no new safety signals were identified. We present 52-week efficacy and safety results.MethodsPatients ≥ 20 years with PSO ≥ 6 months [Psoriasis Area and Severity Index (PASI) ≥ 12, body surface area ≥ 10%, Physician's Global Assessment (PGA) ≥ 3] were randomised 1:2:2 to placebo Q2W, CZP 400 mg Q2W and CZP 200 mg Q2W (400 mg weeks 0/2/4) for 16 weeks. Week 16 PASI 50 responders continued through week 52; CZP 200 mg Q2W-randomised patients were re-randomised 1:1 to CZP 200 mg Q2W or CZP 400 mg Q4W; patients initially randomised to other treatment groups continued in the same group. Outcomes included PASI 75/90/100, PGA 0/1, Dermatology Life Quality Index (DLQI) 0/1, Itch Numeric Rating Scale (INRS) 0, modified Nail Psoriasis Severity Index (mNAPSI), durability of response for week 16 PASI 75/90 responders, and safety.ResultsOf 26/53/48 patients randomised to placebo, CZP 400 mg Q2W and CZP 200 mg Q2W, 2/47/39 completed week 52, respectively. PASI 75/90 responses were generally maintained from weeks 16 to 52 for all CZP doses. Most week 16 PASI 75/90 achievers maintained their response through week 52. PASI 75/90/100 responses at week 52 in the CZP 400 mg Q2W and CZP 200 mg Q2W groups were 83.0/81.1/41.5% and 72.9/60.4/18.8%, respectively; DLQI/INRS remission rates were 64.2/50.9% in CZP 400 mg Q2W and 58.3/27.1% in CZP 200 mg Q2W-treated patients. Reductions in mNAPSI observed for CZP-treated groups were maintained through week 52. No new safety signals were identified.ConclusionCZP treatment resulted in improvements in signs and symptoms of PSO, which were maintained through week 52. The 400 mg Q2W dose could provide additional clinical benefit.Trial registrationNCT03051217.

Project description:Tildrakizumab is a high-affinity, humanized immunoglobulin G1κ, anti-interleukin-23p19 monoclonal antibody recently approved in Japan for treatment of plaque psoriasis. We report results from Japanese patients treated with tildrakizumab in the multinational, randomized, double-blind, placebo-controlled reSURFACE 1 study (clinicaltrials.gov NCT01722331). Adults with moderate to severe plaque psoriasis were randomized (2:2:1) to receive subcutaneous tildrakizumab 100 or 200 mg or placebo every 12 weeks. Placebo recipients were rerandomized to tildrakizumab 100 or 200 mg at week 12. The global study coprimary endpoints were the proportions of patients achieving 75% improvement from baseline Psoriasis Area and Severity Index (PASI 75) and Physician Global Assessment (PGA) response (0/1 with ≥2 grade reduction from baseline) at week 12. Analyses included 158 Japanese patients randomized to tildrakizumab 100 (n = 64) or 200 mg (n = 62) or placebo (n = 32). Japanese patients had higher mean baseline body surface area involvement and PASI versus all reSURFACE 1 patients. At week 12, significantly more Japanese patients receiving tildrakizumab 100 and 200 mg versus placebo achieved PASI 75 (54.7% and 54.8% vs 6.3%, respectively, both nominal p < 0.001) and PGA 0/1 response (54.7% and 56.5% vs 9.4%, respectively, both nominal P < 0.001). Response rates increased over time with maximal efficacy after 22-28 weeks; >80% of patients achieving PASI 75 or PASI 90 at week 28 and continuing tildrakizumab treatment at the same dose maintained response at week 64. From baseline to week 28, absolute PASI decreased from >12 in all patients to ≤2 in >40% and ≤3 in >50% of patients receiving tildrakizumab. Tildrakizumab was generally well tolerated with an adverse event profile similar to that of placebo. Tildrakizumab treatment was associated with durable efficacy in Japanese patients with moderate to severe plaque psoriasis despite greater baseline disease severity versus the global reSURFACE 1 population.
