Project description:Background:Dose escalation is often recommended for loss of response in anti-TNF?-treated patients with Crohn's disease (CD). This 52-week phase 3, multicenter study investigated the efficacy and safety of escalation to adalimumab 80 mg every other week (EOW) in Japanese patients with CD who lost response to maintenance adalimumab 40 mg EOW. Methods:Twenty-eight patients aged ?15 years with moderately to severely active CD who had previously attained and subsequently lost clinical response to maintenance ada limumab received open-label adalimumab 80 mg EOW during weeks 0-50. Loss of response was defined as CD activity index (CDAI) ?200, increases in CDAI ?50 from minimum observed value, and C-reactive protein (CRP) ?1 mg/dL at screening. The primary endpoint was the proportion of patients achieving a CDAI decrease ?50 (CR-50) from baseline at week 8. Results:At weeks 8 and 52, 75.0 and 57.1$ of patients achieved CR-50 and 25.0 and 35.7$ achieved clinical remission (CDAI < 150), respectively; median CRP changes from baseline were -0.39 and -0.77 mg/dL, respectively. Most treatment-emergent adverse events were mild to moderate. Conclusions:Adalimumab dose escalation to 80 mg EOW improved CD activity in patients who had lost response to maintenance adalimumab, with no new safety signals.

Project description:BackgroundMany RRMS patients who had been treated for over 20 years with GA 20 mg/ml daily (GA20) switched to 40 mg/ml three times-a-week (GA40) to reduce injection-related adverse events. Although GA40 is as effective as GA20 in reducing annualized relapse rate and MRI activity, it remains unknown how switching to GA40 from GA20 affects the development of pathogenic and regulatory immune cells.ObjectiveTo investigate the difference in immunological parameters in response to GA20 and GA40 treatments.MethodsWe analyzed five pro-inflammatory cytokines (IL-1β, IL-23, IL-12, IL-18, TNF-α), and three anti-inflammatory/regulatory cytokines (IL-10, IL-13, and IL-27) in serum. In addition, we analyzed six cytokines (IFN-γ, IL-17A, GM-CSF, IL-10, IL-6, and IL-27) in cultured PBMC supernatants. The development of Th1, Th17, Foxp3 Tregs, M1-like, and M2-like macrophages were examined by flow cytometry. Samples were analyzed before and 12 months post switching to GA40 or GA20.ResultsPro- and anti-inflammatory cytokines were comparable between the GA40 and GA20 groups. Development of Th1, Th17, M1-like macrophages, M2-like macrophages, and Foxp3 Tregs was also comparable between the two groups.ConclusionsThe immunological parameters measured in RRMS patients treated with GA40 three times weekly are largely comparable to those given daily GA20 treatment.

Project description:To compare the one-week clinical effects of single doses of dexlansoprazole and esomeprazole on grades A and B erosive esophagitis.We enrolled 175 adult patients with gastroesophageal reflux disease (GERD). The patients were randomized in a 1:1 ratio into two sequence groups to define the order in which they received single doses of dexlansoprazole (n = 88) and esomeprazole (n = 87) for an intention-to-treat analysis. The primary end-points were the complete symptom resolution (CSR) rates at days 1, 3, and 7 after drug administration.Thirteen patients were lost to follow-up, resulting in 81 patients in each group for the per-protocol analysis. The CSRs for both groups were similar at days 1, 3 and 7. In the subgroup analysis, the female patients achieved higher CSRs in the dexlansoprazole group than in the esomeprazole group at day 3 (38.3% vs 18.4%, P = 0.046). An increasing trend toward a higher CSR was observed in the dexlansoprazole group at day 7 (55.3% vs 36.8%, P = 0.09). In the esomeprazole group, female sex was a negative predictive factor for CSR on post-administration day 1 [OR = -1.249 ± 0.543; 95%CI: 0.287 (0.099-0.832), P = 0.022] and day 3 [OR = -1.254 ± 0.519; 95%CI: 0.285 (0.103-0.789), P = 0.016]. Patients with spicy food eating habits achieved lower CSRs on day 1 [37.3% vs 21.4%, OR = -0.969 ± 0.438; 95%CI: 0.380 (0.161-0.896), P = 0.027].The overall CSR for GERD patients was similar at days 1-7 for both the dexlansoprazole and esomeprazole groups, although a higher incidence of CSR was observed on day 3 in female patients who received a single dose of dexlansoprazole.

Project description:UnlabelledThe present study aimed to investigate the pharmacokinetic properties of febuxostat in healthy Chinese male volunteers and evaluate whether the two formulations of febuxostat 40-mg and 80-mg tablets are bioequivalent. A randomized, open-label, 4-way crossover study was conducted in healthy Chinese male volunteers under fasting conditions. 24 eligible subjects were randomized in a 1:1:1:1 ratio to receive a single dose of test or reference formulation of febuxostat 40-mg or 80-mg tablet. The washout period between each administration was 1 week. Plasma febuxostat was quantified by a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Tolerability was evaluated by monitoring adverse events, physical examinations, 12-lead ECG and laboratory tests. After single-dosing of 1 tablet of 40-mg febuxostat, the pharmacokinetic parameters of test and reference formulations were: Tmax 1.22±0.87 and 1.85±1.03 h, Cmax 1689.16±461.31 and 1613.80±608.43 ng·mL-1, AUC0-t 5139.87±1349.28 and 5517.91±2024.26 ng·mL-1·h, AUC0-∞ 5263.06±1339.16 and 5640.48±2040.22 ng·mL-1·h, t1/2 4.82±2.61 and 4.85±1.78 h, respectively. After single-dosing of 1 tablet of 80-mg febuxostat, the pharmacokinetic parameters of test and reference formulations were: Tmax 1.71±1.21 and 2.23±1.55 h, Cmax 2744.47±1157.44 and 2998.17±1200.13 ng·mL-1, AUC0-t 9634.03±2768.25 and 10467.95±3501.65 ng·mL-1·h, AUC0-∞ 9834.32±2730.51 and 10626.63±3504.08 ng·mL-1·h, t1/2 6.25±2.44 and 5.46±1.65 h, respectively. For single-dosing of 1 tablet of 40-mg febuxostat, 90% CIs for the test/reference ratio of AUC0-t, AUC0-∞ and Cmax were 89.79 to 102.55, 90.14 to 102.56 and 93.99 to 129.63, respectively. For single-dosing of 1 tablet of 80-mg febuxostat, 90% CIs for the test/reference ratio of AUC0-t, AUC0-∞ and Cmax were 86.67 to 100.00, 87.50 to 100.51 and 79.48 to 105.99, respectively. This single dose study revealed similar pharmacokinetic properties in healthy Chinese male volunteers as those found in Caucasic population. The test and reference febuxostat tablets formulations met the regulatory criteria for bioequivalence at 40-mg and 80-mg strengths in fasting healthy Chinese male volunteers.Trial registrationChictr.org ChiCTR-TTRCC-14004288.

Project description:IntroductionIn 2018, ixekizumab (80 mg every 2 weeks [Q2W] beyond Week 12) received approval in Japan for patients with generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP). This open-label study evaluated the efficacy and safety of ixekizumab (80 mg Q2W from Week 12 to Week 20) in Japanese patients with GPP and EP.MethodsSeven patients with GPP and five patients with EP were enrolled. An initial dose of 160 mg (subcutaneous [SC] injection) was followed by 80 mg Q2W SC until Week 12. Primary endpoint assessed global improvement score (GIS) by comparing psoriatic findings, Static Physician Global Assessment, Psoriasis Area and Severity Index score, and other evaluations with those at the baseline and were graded as 1 = resolved, 2= improved, 3 = unchanged, and 4 = worsened. Patients who showed GIS = 1 (resolved) at Week 12 completed the study. Patients with GIS ≥ 2 continued to receive ixekizumab 80 mg Q2W until Week 20.ResultsAt Week 12, four of seven patients with GPP showed "resolved," two showed "improved," and one showed "worsened." Of five patients with EP, one showed "resolved" and four showed "improved." Two patients with GPP and four patients with EP continued ixekizumab treatment until Week 20. At Week 20, one of the two patients with GPP showed "resolved" and one patient showed "improved." All four patients with EP showed "improved." One non-drug related serious adverse event was reported by one patient with EP at Week 12. From Week 12 to Week 20, no adverse events (AEs) were reported in patients with GPP, but two mild AEs were reported in one of the four patients with EP.ConclusionsThis study indicates that ixekizumab continuous Q2W dosing is efficacious and safe for patients with GPP and EP.Clinical trial registrationNCT03942042.

Project description:IntroductionAdalimumab, an anti-tumor necrosis factor antibody, is currently available in a 40 mg/0.8 mL formulation. The objective of this analysis was to evaluate injection site-related pain, safety, and tolerability of a 40 mg/0.4 mL formulation of adalimumab that had fewer excipients, a smaller volume, and a delivery presentation with a smaller gauge needle, versus the current 40 mg/0.8 mL formulation in patients with rheumatoid arthritis (RA).MethodsTwo identically designed, phase 2, randomized, single-blind, two-period crossover studies were conducted in Belgium and the Czech Republic (Study 1) and Australia, Canada, and Germany (Study 2). In both studies, adults with RA [biologic-naive or current users of 40 mg/0.8 mL adalimumab with an average injection site-related pain rating ≥3 cm on a visual analog scale (VAS; 0-10 cm)] were randomized to receive 40 mg/0.8 mL or 40 mg/0.4 mL adalimumab at visit 1. After 1-2 weeks (depending on patient medication schedule), patients received the other formulation at visit 2. A pain VAS [McGill Pain Questionnaire (MPQ-SF)] and the Draize scale were evaluated immediately after injection and 15 min postinjection. The primary endpoint was immediate pain after injection.Results64 and 61 patients were randomized in Studies 1 and 2, respectively. Both studies found a clinically relevant and statistically significant lower immediate pain after injection for the 40 mg/0.4 mL versus the 40 mg/0.8 mL formulation. The mean difference on the VAS for the pooled data (-2.48 cm) was also clinically relevant. Most other endpoints in both studies favored the 40 mg/0.4 mL formulation, and its tolerability and safety profile were consistent with 40 mg/0.8 mL adalimumab.ConclusionA 40 mg/0.4 mL adalimumab formulation was well tolerated and associated with less injection site-related pain than the 40 mg/0.8 mL adalimumab formulation.Trial registrationClinicalTrials.gov identifier, NCT01561313 and NCT01502423.FundingAbbVie.

Project description:AimsTo evaluate pharmacokinetic equivalence and preliminary safety of the adalimumab biosimilar CT-P17 administered via autoinjector (CT-P17 AI) or prefilled syringe (CT-P17 PFS) in healthy subjects.MethodsThis phase I, open-label study (ClinicalTrials.gov: NCT04295356) randomised subjects (1:1) to receive a single 40-mg (100 mg/mL) dose of CT-P17 AI or CT-P17 PFS. Primary endpoint was pharmacokinetic equivalence of CT-P17 AI to CT-P17 PFS for: area under the concentration-time curve from time zero to infinity (AUC0-inf ); area under the concentration-time curve from time zero to the last quantifiable concentration (AUC0-last ); maximum serum concentration (Cmax ). Equivalence was determined if the 90% confidence interval for the geometric least-squares mean ratio was within the 80-125% equivalence margin. Additional pharmacokinetic endpoints, safety and immunogenicity were evaluated.ResultsOf 193 subjects who were randomised (98 CT-P17 AI; 95 CT-P17 PFS), 180 received study drug. Pharmacokinetic equivalence was demonstrated: 90% confidence intervals were within the 80-125% equivalence margin (AUC0-inf : 93.98-114.29; AUC0-last : 91.09-121.86; Cmax : 94.08-111.90). Mean serum CT-P17 concentrations, secondary pharmacokinetic parameters and numbers of subjects with antidrug antibodies (ADAs) or neutralising ADAs were comparable between groups. AUC0-inf , AUC0-last and Cmax were numerically lower for ADA-positive than for ADA-negative subjects (both groups); pharmacokinetic equivalence was also demonstrated among ADA-positive subjects. CT-P17 AI and CT-P17 PFS were well tolerated, with comparable overall safety profiles.ConclusionsCT-P17 AI and CT-P17 PFS were pharmacokinetically equivalent. Overall safety and immunogenicity were comparable between the 2 delivery devices.

Project description:IntroductionTo examine the long-term efficacy and safety of duloxetine in the treatment of Japanese patients with diabetic neuropathic pain, we carried out a 52-week, randomized, open-label extension of a 12-week, double-blind, placebo-controlled study.Materials and methodsJapanese adults with diabetic neuropathic pain who completed the double-blind study were eligible for this long-term study, carried out at 71 sites in Japan (March 2008 to March 2010). Participants (n = 258) were re-randomized (1:1) to 40 mg/day or 60 mg/day duloxetine. Pain (Brief Pain Inventory severity and interference), quality of life (Patient's Global Impression of Improvement), and safety (primary outcome; adverse events, vital signs, metabolic measures) were measured.ResultsSignificant (P < 0.0001) and sustained improvements (change ± standard deviation; n = 257) were observed in Brief Pain Inventory severity (average pain score -2.1 ± 1.7). Improvements were also seen in Brief Pain Inventory interference (mean of subscores -0.96 ± 1.52) and Patient's Global Impression of Improvement (-0.9 ± 1.1) scores; these scores decreased significantly (P < 0.0001) during the long-term study. Frequently reported adverse events included somnolence (13.6%), constipation (13.2%) and nausea (10.5%). Increases were observed in plasma glucose, glycosylated hemoglobin and total cholesterol levels, and in bodyweight and heart rate; however, none of these were clinically meaningful. Overall, there were no clinically significant safety concerns.ConclusionsThis is the first publication of a long-term study carried out in Asia with an entirely Japanese patient population to suggest that long-term duloxetine therapy for diabetic neuropathic pain is effective and has an acceptable safety profile.

Project description:ObjectiveThe present study compared the bioavailability of subcutaneous (s.c.) Chemi Enoxaparin with Clexane (80 mg/0.8 mL) under fasting conditions in healthy subjects.Materials and methodsThis study was an open-label, randomized, single-dose, two-treatment period crossover study. We included healthy male and female subjects aged 18 - 55 years with a body mass index of 18 - 30 kg/m2. The primary pharmacodynamic endpoints were anti-FIIa and anti-FXa activity. Bioequivalence was achieved when the 95% confidence interval (CI) for the geometric means of Cmax and AUC0-t was between 80.00 and 125.00%.Results47 subjects were randomized for the treatment sequences. The 95% CI of the ratios of the geometric least squared means of anti-FXa activity was 96.28 - 102.65 IU/mL for Cmax and 100.67 - 105.15 h×IU/mL for the AUC0-t of Chemi Enoxaparin compared with those of Clexane, and for anti-FIIa activity, they were 86.65 - 96.73 IU/mL for the Cmax and 87.72 - 97.25 h×IU/mL AUC0-t, which met the criterion for bioequivalence. The number of subjects reporting at least 1 treatment-emergent adverse event (TEAE) was low, mostly of mild severity, and similar for both compounds.ConclusionChemi enoxaparin is bioequivalent to the reference enoxaparin, and both compounds show similar tolerability and safety profiles.

Project description:ObjectiveTo compare the safety and efficacy of switching from reference adalimumab to adalimumab biosimilar CT-P17 with continuing reference adalimumab/CT-P17 in active RA.MethodsThis double-blind, phase III study randomized (1:1) subjects with active RA to receive 40 mg (100 mg/ml) CT-P17 or European Union-sourced reference adalimumab subcutaneously every 2 weeks (Q2W) until week (W) 24 [treatment period (TP) 1]. Thereafter, subjects receiving reference adalimumab were randomized (1:1) to continue reference adalimumab or switch to CT-P17 from W26 (both Q2W until W48; TP2). Subjects receiving CT-P17 in TP1 continued CT-P17. W0-W24 results were previously reported; we present W26-W52 findings. End points were efficacy (including joint damage progression), pharmacokinetics, safety and immunogenicity.ResultsOf 607 subjects who initiated TP2 treatment, 303 continued CT-P17, 153 continued reference adalimumab and 151 switched to CT-P17. Efficacy improvements up to W24 were maintained during TP2; efficacy was comparable among groups. At W52, 20% improvement in ACR response rates were 80.5% (continued CT-P17), 77.8% (continued reference adalimumab) and 82.2% (switched to CT-P17). Joint damage progression was minimal. Mean trough serum adalimumab concentrations were similar among groups. CT-P17 and reference adalimumab safety profiles were numerically similar and switching did not affect immunogenicity. At W52, 28.4% (continued CT-P17), 27.0% (continued reference adalimumab) and 28.3% (switched to CT-P17) of subjects were anti-drug antibody-positive.ConclusionEfficacy, pharmacokinetics, safety and immunogenicity of CT-P17 and reference adalimumab were comparable after 1 year of treatment, including after switching from reference adalimumab to CT-P17.Trial registrationClinicalTrials.gov, http://clinicaltrials.gov, NCT03789292.
