Vedolizumab in Japanese patients with ulcerative colitis: A Phase 3, randomized, double-blind, placebo-controlled study.

ABSTRACT: BACKGROUND:Vedolizumab safety and efficacy have been established in many populations all over the world, but have never been studied in Japan. We report results from a Phase 3, randomized, double-blind, placebo-controlled study of vedolizumab in Japanese patients with active ulcerative colitis (UC). METHODS:Patients with moderate-to-severe UC were enrolled into Cohort 1 (double-blinded) or Cohort 2 (open-label) in the induction phase. Cohort 1 was randomized 2:1 to receive 300 mg vedolizumab or placebo, while Cohort 2 received vedolizumab 300 mg only, at Weeks 0, 2, and 6. Patients from Cohorts 1 and 2 showing a clinical response to vedolizumab at Week 10 were randomized 1:1 to receive vedolizumab or placebo (double-blinded) at Week 14 and then every 8 weeks up to Week 54 as the maintenance phase. The primary endpoint was clinical response at Week 10, for the induction phase, and clinical remission at Week 60, for the maintenance phase. RESULTS:A total of 292 patients were enrolled into the induction phase (246 in Cohort 1, 46 in Cohort 2); 83 patients achieved response to vedolizumab and were subsequently enrolled into the maintenance phase. Clinical response rates at Week 10 were 39.6% (65/164) and 32.9% (27/82) in the vedolizumab and placebo groups in Cohort 1, respectively (adjusted odds ratio [AOR] = 1.37, 95% CI 0.779-2.399; p = 0.2722). In the maintenance phase, clinical remission rate at Week 60 was significantly higher in the vedolizumab group, at 56.1% (23/41), versus 31.0% (13/42) for placebo (AOR = 2.88, 95% CI 1.168-7.108; p = 0.0210). Most adverse events were mild to moderate in intensity, and no deaths occurred during the study period. CONCLUSIONS:Vedolizumab showed numerically greater efficacy compared with placebo as induction therapy, but the difference was not statistically significant. Vedolizumab was significantly superior to placebo as maintenance therapy in Japanese patients with UC. Vedolizumab has favourable safety and tolerability in these patients.

Project description:IntroductionFibromyalgia is characterized by widespread pain and is often accompanied by accessory symptoms. There are limited treatment options for this condition in Japan. Therefore, we conducted a phase III study to assess the efficacy and safety of duloxetine in Japanese patients with fibromyalgia.MethodsThis randomized, double-blind, placebo-controlled, parallel-group trial was conducted in Japan. Outpatients who met the American College of Rheumatology 1990 criteria for fibromyalgia and whose Brief Pain Inventory (BPI) average pain score was ≥4 were randomized to duloxetine 60 mg or placebo once daily for 14 weeks. The primary efficacy measure was the change in the BPI average pain score from baseline. Secondary efficacy, quality of life (QoL), and safety outcomes were also evaluated. Mixed-effects model repeated-measures (MMRM) analysis and last observation carried forward (LOCF) analysis of covariance were used to evaluate the primary efficacy measure.ResultsOverall, 393 patients were randomized to receive either duloxetine (n = 196) or placebo (n = 197). The MMRM analysis revealed no significant difference between duloxetine and placebo regarding the change in BPI average pain scores at week 14. Based on LOCF analysis, a statistically significant improvement in the change in BPI average pain scores at week 14 was observed for patients treated with duloxetine compared with placebo. Duloxetine treatment was associated with improved outcomes in nearly all secondary and post hoc analyses. The treatment was generally well tolerated. Somnolence, nausea, and constipation were the most common treatment-emergent adverse events in the duloxetine group. The discontinuation rates due to treatment-emergent adverse events were similar in both groups.ConclusionsAlthough the MMRM analysis did not demonstrate superiority of duloxetine over placebo, duloxetine treatment was associated with improved outcomes in secondary and post hoc analyses of the mean change in the BPI average pain score and most of the secondary outcomes, including analgesia and QoL. Duloxetine treatment was safe and well tolerated. These results suggest that duloxetine treatment could be associated with improvements in pain relief and QoL in Japanese patients with fibromyalgia.Trial registrationClinicalTrials.gov Identifier: NCT01552057 .

Project description:BackgroundThe global phase 3 studies of golimumab [PURSUIT-SC and PURSUIT-maintenance (M)], an anti-tumor necrosis factor-α (anti-TNFα) antibody, have demonstrated clinical efficacy and safety as induction and maintenance therapies in patients with moderate to severely active ulcerative colitis (UC). This study aimed to evaluate the efficacy and safety of golimumab as maintenance therapy in the Japanese population.MethodsIn this phase 3, double-blind (DB), placebo-controlled, parallel group, randomized withdrawal study, 144 Japanese patients with moderately to severely active UC received golimumab doses of 200 mg (at week 0) and 100 mg (at week 2) subcutaneously during the 6-week open-label induction phase. Patients who responded to golimumab induction therapy entered the DB maintenance (M) phase and were randomized (1:1) to receive 100 mg of golimumab subcutaneous injection (SC) or placebo every 4 weeks for 52 weeks. The primary endpoint was clinical response through M-week 54; secondary endpoints included clinical remission and mucosal healing at M-week 30 and 54.ResultsAmong induction responders, more patients on golimumab treatment (56.3%) maintained clinical response through M-week 54 versus the placebo group (19.4%). At both M-week 30 and 54, 50% golimumab-treated patients achieved clinical remission versus the placebo group (6.5%) and a higher proportion of patients on golimumab (59.4%) experienced mucosal healing than the placebo group (16.1%). Incidence of treatment-emergent adverse events was 96.9% in the golimumab group and 71% in the placebo group. Overall, the efficacy and safety results in this study were comparable with those observed in global studies.ConclusionsGolimumab SC treatment maintained clinical efficacy through week 54 among induction responders, and no new safety signals were observed in the patients with moderate to severely active UC.Clinical trial registrationThe study is registered at ClinicalTrials.gov NCT01863771.

Project description:A 14-week, randomized, double-blind, multicenter, placebo-controlled study of Japanese patients with chronic low back pain (CLBP) who were randomized to either duloxetine 60?mg once daily or placebo.This study aimed to assess the efficacy and safety of duloxetine monotherapy in Japanese patients with CLBP.In Japan, duloxetine is approved for the treatment of depression, diabetic neuropathic pain, and pain associated with fibromyalgia; however, no clinical study of duloxetine has been conducted for CLBP.The primary efficacy measure was the change in the Brief Pain Inventory (BPI) average pain score from baseline to Week 14. Secondary efficacy measures included BPI pain (worst pain, least pain, pain right now), Patient's Global Impression of Improvement, Clinical Global Impressions of Severity, and Roland-Morris Disability Questionnaire, among other measures, and safety and tolerability.In total, 458 patients were randomized to receive either duloxetine (n?=?232) or placebo (n?=?226). The BPI average pain score improved significantly in the duloxetine group compared with that in the placebo group at Week 14 [-2.43?±?0.11 vs. -1.96?±?0.11, respectively; between-group difference (95% confidence interval),?-?0.46 [-0.77 to-0.16]; P?=?0.0026]. The duloxetine group showed significant improvement in many secondary measures compared with the placebo group, including BPI pain (least pain, pain right now) (between-group difference: -1.69?±?0.10, P?=?0.0009; -2.42?±?0.12, P P?=?0.0230, respectively), Patient's Global Impression of Improvement (2.46?±?0.07, P?=?0.0026), Clinical Global Impressions of Severity (-1.46?±?0.06, P?=?0.0019), and Roland-Morris Disability Questionnaire (-3.86?±?0.22, P?=?0.0439). Adverse events occurring at a significantly higher incidence in the duloxetine group were somnolence, constipation, nausea, dizziness, and dry mouth, most of which were mild or moderate in severity and were resolved or improved.Duloxetine 60?mg was effective and well tolerated in Japanese CLBP patients.2.

Project description:OBJECTIVES: VSL#3 is a high-potency probiotic mixture that has been used successfully in the treatment of pouchitis. The primary end point of the study was to assess the effects of supplementation with VSL#3 in patients affected by relapsing ulcerative colitis (UC) who are already under treatment with 5-aminosalicylic acid (ASA) and/or immunosuppressants at stable doses. METHODS: A total of 144 consecutive patients were randomly treated for 8 weeks with VSL#3 at a dose of 3,600 billion CFU/day (71 patients) or with placebo (73 patients). RESULTS: In all, 65 patients in the VSL#3 group and 66 patients in the placebo group completed the study. The decrease in ulcerative colitis disease activity index (UCDAI) scores of 50% or more was higher in the VSL#3 group than in the placebo group (63.1 vs. 40.8; per protocol (PP) P=0.010, confidence interval (CI)₉₅(%) 0.51-0.74; intention to treat (ITT) P=0.031, CI₉₅(%) 0.47-0.69). Significant results with VSL#3 were recorded in an improvement of three points or more in the UCDAI score (60.5% vs. 41.4%; PP P=0.017, CI₉₅(%) 0.51-0.74; ITT P=0.046, CI₉₅(%) 0.47-0.69) and in rectal bleeding (PP P=0.014, CI₉₅(%) 0.46-0.70; ITT P=0.036, CI₉₅(%) 0.41-0.65), whereas stool frequency (PP P=0.202, CI₉₅(%) 0.39-0.63; ITT P=0.229, CI₉₅(%) 0.35-0.57), physician's rate of disease activity (PP P=0.088, CI₉₅(%) 0.34-0.58; ITT P=0.168, CI₉₅(%) 0.31-0.53), and endoscopic scores (PP P=0.086, CI₉₅(%) 0.74-0.92; ITT P=0.366, CI₉₅(%) 0.66-0.86) did not show statistical differences. Remission was higher in the VSL#3 group than in the placebo group (47.7% vs. 32.4%; PP P=0.069, CI₉₅(%) 0.36-0.60; ITT P=0.132, CI₉₅(%) 0.33-0.56). Eight patients on VSL#3 (11.2%) and nine patients on placebo (12.3%) reported mild side effects. CONCLUSIONS: VSL#3 supplementation is safe and able to reduce UCDAI scores in patients affected by relapsing mild-to-moderate UC who are under treatment with 5-ASA and/or immunosuppressants. Moreover, VSL#3 improves rectal bleeding and seems to reinduce remission in relapsing UC patients after 8 weeks of treatment, although these parameters do not reach statistical significance.
