The purpose of this study is to evaluate the efficacy of ustekinumab in participants with active systemic lupus erythematosus (SLE) who have not adequately responded to one or more standard of care treatments.
The purpose of this study is to determine in hospitalized adult participants infected with human metapneumovirus (hMPV - a virus closely related to respiratory syncytial virus (RSV) and has been identified as an important cause of acute respiratory infections, affecting all age groups) the dose-response relationship of multiple regimens of lumicitabine on antiviral activity based on nasal hMPV shedding using quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) assay.
A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Safety and Efficacy Study of Dutogliptin in Combination with Filgrastim in Early Recovery Post-Myocardial Infarction
The purpose of this study is to compare the efficacy of treatment with ustekinumab or adalimumab in biologic naive participants with moderately-to-severely active Crohn's disease (CD) who have previously failed or were intolerant to conventional therapy (corticosteroids and/or immunomodulators, such as azathioprine, 6-mercaptopurine, or methotrexate), as measured by clinical remission at one year.
IPILIMUMAB Extended Access Program for patients who received chemotherapy and / or radiation therapy before the protocol, before or after the operation.
This study is a double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of IV ETX2514SUL in patients with complicated urinary tract infections (cUTIs) who are otherwise relatively healthy.
The aim of this study is to determine the effectiveness of DentalVibe (DV) in reducing injection pain and anxiety associated with local anaesthesia in paediatric patients. The clinical trial is a randomized split-mouth assignment. Included patients are 8-12 years old requiring local anesthetic infiltration with conventional syringe (CS) for extraction of two primary maxillary molars bilaterally. Eligible patients undergo two single-visit treatments after CFSS-DS measurement before each, where as DV is allocated to either first or second local anaesthesia procedure. Primary outcome measure will be pain felt during injection, reported by patient on VAS. Secondary outcome measures: self-reported anxiety during injection on FIS; pain-related behavior according to FLACC scale; heart-rate dynamics; patient preference to local anaesthesia method - CS or CS+DV.
The study investigates the effect of 4 weeks of twice daily treatment of four different doses of RPL554 (a phosphodiesterase [PDE]3/4 inhibitor) or placebo in patients with moderate to severe COPD. Patients will be equally allocated to one of the five treatment options.
This is a study of the safety and efficacy of ceftobiprole in pediatric patients with hospital-acquired bacterial pneumonia (HAP) or community-acquired bacterial pneumonia (CAP) requiring hospitalization.
