A Randomized, blinded assessor study to Evaluate the efFIcacy and safety of etanercept 50 mg once weekly plus as Needed topical agent vs. Etanercept 50 mg twice weekly in patients with moderate to severe plaque psoriasis (REFINE).

ABSTRACT: Topical corticosteroids are used with systemic therapies for treatment of plaque psoriasis, but data from randomized clinical trials to document efficacy of combination therapy are lacking.To evaluate efficacy and safety of adding topical corticosteroid therapy from the time that etanercept dosage is reduced from initial label dose [50 mg twice weekly (BIW)] to maintenance dose [50 mg once weekly (QW)].In this phase 3b, multicentre, randomized, open-label study, patients with moderate-to-severe plaque psoriasis received etanercept 50 mg BIW for 12 weeks, and then were randomized to etanercept 50 mg BIW or 50 mg QW plus topical agent as needed to achieve static physician global assessment (sPGA) status of clear for 12 weeks. Endpoints included percentage change in Psoriasis Area and Severity Index (PASI) score from week 12 to week 24 (primary endpoint); proportion of patients achieving 50% improvement in (PASI 50), PASI 75 and PASI 90; patients achieving sPGA of clear/almost clear; and change in affected body surface area (BSA).Mean difference [95% confidence interval (CI)] between etanercept arm (n = 140) and etanercept plus topical arm (n = 142) in change in PASI score from week 12 to week 24 was 16.2% (-3.5%, 35.8%). PASI response rates were similar between groups. Percentage (95% CI) of patients achieving sPGA status of clear/almost clear was 40.6% (32.5%, 48.6%) and 45.8% (37.6%, 54.0%) at week 12 for patients in etanercept and etanercept plus topical arms, respectively, and 53.5% (45.3%, 61.7%) and 45.4% (37.2%, 53.6%) at week 24. Difference (95% CI) between groups in change in affected BSA from week 12 to week 24 was 4.9% (-23.4%, 33.2%).Patients who received etanercept 50 mg QW at week 12 plus as-needed topical therapy and those who stayed on etanercept 50 mg BIW maintained clinical response through week 24 with no notable differences in PASI responses.

Project description:A 48-week, multicenter, randomized, double-blind, double-dummy, active-controlled, non-inferiority trial (the TWICE study) conducted in Japanese primary osteoporosis patients with a high risk of fractures demonstrated that a 28.2-?g twice-weekly regimen of teriparatide can provide comparable efficacy to a 56.5-?g once-weekly regimen of teriparatide, while also improving safety.IntroductionWhile a 56.5-?g once-weekly regimen of teriparatide has high efficacy for osteoporosis, treatment continuation rates are low, with one of the major causes being adverse drug reactions such as nausea or vomiting. The TWICE study was therefore conducted to investigate whether a twice-weekly regimen with 28.2-?g teriparatide can provide comparable efficacy to the 56.5-?g once-weekly regimen while improving safety.MethodsA 48-week, multicenter, randomized, double-blind, double-dummy, active-controlled, non-inferiority trial was conducted in Japan. Patients with primary osteoporosis aged ??65 years at high risk of fractures (n?=?553) were randomly allocated to the 28.2-?g twice-weekly group (n?=?277) or the 56.5-?g once-weekly group (n?=?276). The primary endpoint was the percentage change in lumbar spine (L2-L4) bone mineral density (BMD) at final follow-up.ResultsThe percentage changes in lumbar spine (L2-L4) BMD at final follow-up in the 28.2-?g twice-weekly and 56.5-?g once-weekly groups were 7.3% and 5.9%, respectively; the difference (95% confidence interval [CI]) in percentage change was 1.3% (0.400-2.283%). Since the lower limit of the 95% CI was above the pre-specified non-inferiority margin (-?1.6%), non-inferiority of the 28.2-?g twice-weekly group was demonstrated. Adverse drug reactions were significantly less frequent in the 28.2-?g twice-weekly group (39.7% vs 56.2%; p?<?0.01); the incidence of major adverse drug reactions was lower, and the number of subjects who discontinued due to adverse drug reactions was less in the 28.2-?g twice-weekly group.ConclusionsA 28.2-?g twice-weekly regimen of teriparatide can provide comparable efficacy to a 56.5-?g once-weekly regimen while improving safety.Clinical trial registrationJapicCTI-163477 .

Project description:Anaemia is a common complication of chronic kidney disease and prevalence increases with declining renal function. Renal anaemia has significant implications for the well-being and quality of life of patients and impacts on morbidity and mortality. Anaemia can be well managed by therapy with erythropoiesis-stimulating agents (ESAs). Previous clinical trials have shown that the only human cell-line-derived ESA, epoetin delta, is well tolerated and effective in maintaining haemoglobin levels in anaemic patients with chronic kidney disease. The half-life of epoetin delta suggests that administration of this agent is feasible once weekly and once every two weeks. We report on the design and rationale of a trial to compare once weekly vs. twice weekly, and once weekly vs. once every two weeks dosing of epoetin delta.This is a randomized, open-label, multicentre trial. Patients aged 18 years or above with chronic kidney disease (Stages 3-5) are eligible to enter this trial. Two groups of patients form the trial population, those naïve to ESA therapy and those previously stable on ESA therapy. There are two primary objectives of this trial: 1) to demonstrate non-inferiority between twice weekly and once weekly dosing of epoetin delta in previously naïve patients (assessed by haemoglobin at Week 24); 2) to demonstrate non-inferiority between once weekly and once every two weeks dosing in previously stable patients (assessed by average haemoglobin over Weeks 16-24). Among the secondary analyses will be assessments of haematocrit, number(%) of patients meeting predefined targets for haemoglobin and haematocrit levels, and comparisons of average dose. All patients will receive study medication for 24 weeks and dose will be adjusted according to a predefined algorithm to achieve and maintain haemoglobin >or= 11 g/dL. All patients completing this trial are eligible to enter a 2-year follow-up study to enable monitoring of emergent adverse events, anti-erythropoietin antibody responses, maintenance of efficacy and changes in diabetic retinopathy status.To our knowledge, this trial is the first to randomize ESA-naïve patients to different dosing regimens of the same ESA. Data generated will help in guiding the most appropriate dosing frequency for epoetin delta, particularly in those patients new to epoetin delta therapy.ClinicalTrials.gov: NCT00450333.

Project description:BackgroundThe efficacy, safety and tolerability of lumiracoxib, a novel selective cyclooxygenase-2 (COX-2) inhibitor, has been demonstrated in previous studies of patients with osteoarthritis (OA). As it is important to establish the long-term safety and efficacy of treatments for a chronic disease such as OA, the present study compared the effects of lumiracoxib at doses of 100 mg once daily (o.d.) and 100 mg twice daily (b.i.d.) with those of celecoxib 200 mg o.d. on retention on treatment over 1 year.MethodsIn this 52-week, multicentre, randomised, double-blind, parallel-group study, male and female patients (aged at least 40 years) with symptomatic primary OA of the hip, knee, hand or spine were randomised (1:2:1) to lumiracoxib 100 mg o.d. (n = 755), lumiracoxib 100 mg b.i.d. (n = 1,519) or celecoxib 200 mg o.d. (n = 758). The primary objective of the study was to demonstrate non-inferiority of lumiracoxib at either dose compared with celecoxib 200 mg o.d. with respect to the 1-year retention on treatment rate. Secondary outcome variables included OA pain in the target joint, patient's and physician's global assessments of disease activity, Short Arthritis assessment Scale (SAS) total score, rescue medication use, and safety and tolerability.ResultsRetention rates at 1 year were similar for the lumiracoxib 100 mg o.d., lumiracoxib 100 mg b.i.d. and celecoxib 200 mg o.d. groups (46.9% vs 47.5% vs 45.3%, respectively). It was demonstrated that retention on treatment with lumiracoxib at either dose was non-inferior to celecoxib 200 mg o.d. Similarly, Kaplan-Meier curves for the probability of premature discontinuation from the study for any reason were similar across the treatment groups. All three treatments generally yielded comparable results for the secondary efficacy variables and all treatments were well tolerated.ConclusionLong-term treatment with lumiracoxib 100 mg o.d., the recommended dose for OA, was as effective and well tolerated as celecoxib 200 mg o.d. in patients with OA.Trial registrationclinicaltrials.gov NCT00145301.
