Efficacy and safety of a novel high-dose mesalazine tablet in mild to moderate active ulcerative colitis: a double-blind, multicentre, randomised trial.

ABSTRACT: Adherence to mesalazine treatment is essential for the successful treatment of ulcerative colitis.The objective of this study was to compare the efficacy, safety and preference of a novel high-dose 1000?mg mesalazine tablet versus conventional treatment for ulcerative colitis remission.This pivotal phase III trial compared one 1000?mg mesalazine tablet (M1000 group) versus two registered 500?mg mesalazine tablets (M2x500 group), both taken three times daily, in patients with mild to moderately active ulcerative colitis. The primary efficacy variable was clinical remission at week 8.A total of 306 patients were considered for intent-to-treat analysis. Clinical remission was achieved in 45.0% of the patients in the M1000 group versus 41.9% in the M2x500 group (P?

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.

Project description:BackgroundBGB-DXP593, a neutralising monoclonal antibody against SARS-CoV-2, has demonstrated strong activity in reducing viral RNA copy number in SARS-CoV-2-infected animal models. We aimed to examine the efficacy and safety of BGB-DXP593 in ambulatory patients with mild-to-moderate COVID-19.MethodsThis global, randomised, double-blind, phase 2 study (ClinicalTrials.govNCT04551898) screened patients from 20 sites in Australia, Brazil, Mexico, South Africa, and the USA from December 2, 2020, through January 25, 2021. Patients with a first-positive SARS-CoV-2 test (positive reverse transcription-polymerase chain reaction test or authorised antigen test) ≤3 days before screening and mild-to-moderate COVID-19 symptoms for ≤7 days before treatment were randomised 1:1:1:1 to receive a single intravenous infusion of BGB-DXP593 5, 15, or 30 mg/kg, or placebo. The primary endpoint was change from baseline to Day 8 in viral RNA copies/mL as measured in nasopharyngeal swabs. Secondary endpoints were hospitalisation rate due to worsening COVID-19 and treatment-emergent adverse events (TEAEs). A prespecified exploratory endpoint was change in viral RNA copy number in saliva.FindingsRelative to the natural rate of clearance as assessed in placebo-exposed patients (-3.12 log10 copies/mL), no significant differences in nasopharygneal viral RNA copy number changes were observed (-2.93 to -3.63 log10 copies/mL) by Day 8 in BGB-DXP593-treated patients. Reductions from baseline to Day 8 in saliva viral RNA copy number were larger with BGB-DXP593 5 mg/kg (-1.37 log10 copies/mL [90% confidence interval -2.14, -0.61]; nominal p = 0.003) and 15 mg/kg (-1.26 [-2.06, -0.46]; nominal p = 0.01) vs placebo, and differences favoring BGB-DXP593 were observed by Day 3, although not statistically significant; no difference from placebo was observed for BGB-DXP593 30 mg/kg (-0.71 [-1.45, 0.04]; nominal p = 0.12). Hospitalisation rate due to COVID-19 was numerically lower with BGB-DXP593 (pooled: 2/134 patients; 1.5%) vs placebo (2/47 patients; 4.3%), although not statistically significant. Incidence of TEAEs was similar across treatment groups. No TEAE led to treatment discontinuation. Five serious TEAEs occurred, all attributed to COVID-19 pneumonia.InterpretationBGB-DXP593 was well tolerated. Although nasopharyngeal swab SARS-CoV-2 viral RNA copy number was not significantly decreased compared with placebo, viral RNA copy number was inconsistently reduced by Day 8 in saliva at some doses as low as 5 mg/kg.FundingBeiGene, Ltd.
