Efficacy and safety of tildrakizumab for plaque psoriasis with continuous dosing, treatment interruption, dose adjustments and switching from etanercept: results from phase III studies.

ABSTRACT: BACKGROUND:Chronic psoriasis may require medication adjustments over time. OBJECTIVES:To evaluate the efficacy/safety of tildrakizumab in subgroups from the reSURFACE studies (N = 1862) that received continuous dosing, higher/lower dosing, treatment interruption/reinitiation and initiation. METHODS:Responders [Psoriasis Area and Severity Index (PASI) ? 75%] and partial responders (PASI ? 50% to < 75%) in Part 3 of the reSURFACE studies (weeks 28-52 or week 64) who received tildrakizumab 200 mg or 100 mg were rerandomized to the same dosage (T100/T100 or T200/T200), a higher/lower dosage (T100/T200 or T200/T100) or placebo (PBO) (T100/PBO or T200/PBO). Patients receiving PBO who relapsed were reinitiated to tildrakizumab. Etanercept (ETN) week-28 partial responders and nonresponders (PASI < 50%) received tildrakizumab 200 mg (ETN/T200). RESULTS:Among T100/T100 and T200/T200 week-28 partial responders, the proportion of patients who achieved as-observed PASI 75 responses increased over time. Among T100/T200 week-28 partial responders, PASI 75 responses increased from week 32 (38·5%) to week 52 (63·2%) and remained consistent in T200/T100 week-28 responders. Among patients who relapsed in the T100/PBO and T200/PBO groups, 86% and 83% of those who reinitiated tildrakizumab achieved PASI 75 by week 64, respectively. Among ETN/T200 week-28 partial responders, PASI 75 responses (nonresponder imputation) increased from week 32 (24·1%) to week 52 (74·7%). PASI 90, PASI 100 and Physician's Global Assessment responses were consistent with PASI 75 results. Treatment was well tolerated. CONCLUSIONS:Patients generally fared well with tildrakizumab maintenance, reinitiation, dose adjustment or initiation. What's already known about this topic? Tildrakizumab demonstrated significant efficacy vs. placebo with a positive safety profile during the first 28 weeks of treatment in two randomized double-blind trials. What does this study add? Treatment scenarios with tildrakizumab, such as long-term continuous dosing (up to 64 weeks), treatment interruption/reinitiation and switching from another biologic, can be part of the management of plaque psoriasis with a reasonable expectation of efficacy and tolerability.

Project description:Psoriasis affects 1-3% of the population, in some people causing changes to the nails and joints in addition to skin lesions. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of systemic drug treatments, topical drug treatments, and non-drug treatments (other than ultraviolet light) for chronic plaque psoriasis? What are the effects of ultraviolet light treatments for chronic plaque psoriasis? What are the effects of combined treatment with drugs plus ultraviolet light on chronic plaque psoriasis? What are the effects of combined systemic plus topical drug treatments for chronic plaque psoriasis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2007 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 122 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, adding calcipotriol (topical) to psoralen plus ultraviolet light A or ultraviolet light B, adding oral retinoids to psoralen plus ultraviolet A (PUVA), alefacept, balneotherapy, ciclosporin, dithranol, T cell-targeted therapies, cytokine blocking agents, emollients (alone or plus ultraviolet light B), etanercept, fish oil supplementation, fumaric acid derivatives, Goeckerman treatment, heliotherapy, infliximab, Ingram regimen, keratolytics (salicylic acid, urea), leflunomide, methotrexate, oral pimecrolimus, phototherapy plus balneotherapy, psoralen plus ultraviolet A, psychotherapy, oral retinoids (alone or with ultraviolet light B), systemic drug treatments plus topical vitamin D derivatives, tars, tazarotene, topical corticosteroids (alone or plus oral retinoids), topical Vitamin D derivatives, ultraviolet light A, and ultraviolet light B.

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.
