Otherwise healthy index patients (IP) are randomized to either baloxavir marboxil or placebo if their influenza symptoms onset was within 48 hours of screening. Their households are enrolled within 24 hours of randomization if at least 1 household contacts (HHC) have not received influenza vaccine within 6 months of screening and if all HHC screen negative for influenza infection. The main endpoints are assessed based on multiple respiratory swabs, obtained from both IP and HHC up to 9 (+/-1) days post IP randomization, and through the assessment of symptoms.
Multicenter, open-label, safety and tolerability study of ascending doses of HepaStem in patients with cirrhotic and pre-cirrhotic non-alcoholic steato-hepatitis (NASH) to determine the safety and tolerability of ascending single and repeated doses of HepaStem administered to patients with cirrhotic and pre-cirrhotic non-alcoholic steato-hepatitis (NASH)
This is a 52 week Phase 2b study designed to evaluate the efficacy at 16 weeks and to evaluate the safety and efficacy up to 1 year in subjects with active psoriatic arthritis.
The objective of this study was to collect data both retrospectively and prospectively in order to evaluate the long-term outcomes, durability of effect, and real-world treatment patterns following treatment with Cladribine Tablets or placebo in participants with multiple sclerosis (MS) who were previously participated in the parent studies (ORACLE MS and CLARITY/CLARITY-EXT).
This is a 24-week randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the efficacy and safety of intranasal administration of 186 and 372 μg twice daily (BID) of OPN-375 in subjects with chronic Rhinosinusitis (CRS) without nasal polyps
The purpose of this study is to evaluate the safety and tolerability of MEDI8897 compared to palivizumab when administered to preterm infants entering their first RSV season and children with chronic lung disease (CLD) and congenital heart disease (CHD) entering their first and second RSV season.
The purpose of this study is to determine whether oral etrasimod is a safe and effective treatment for moderately to severely active ulcerative colitis.
This is Phase 3, Randomized, Placebo-controlled study to demonstrate superiority of CT-P13 SC over Placebo SC in Patients With Moderately to Severely Active Crohn's Disease
This phase 3 clinical study is a randomized, observer-blind, multicenter study of QIVc versus a non-influenza vaccine in subjects 6 months though 47 months of age. The purpose of this study is to evaluate efficacy of QIVc in the prevention of Reverse transcription polymerase chain reaction (RT-PCR) confirmed influenza A or B disease in children 6 through 47 months of age, compared to a non-influenza vaccine.
Primary Objective: To evaluate the efficacy of dupilumab administered every 2 weeks in patients with moderate-or severe Chronic Obstructive Pulmonary Disease (COPD) as measured by - Annualized rate of acute moderate and severe COPD exacerbation (AECOPD) Secondary Objectives: To evaluate the effect of dupilumab administered every 2 weeks on - Pre-bronchodilator forced expiratory volume in 1 second (FEV1) over 12 weeks compared to placebo - Health related quality of life, assessed by the change from baseline to Week 52 in the St. George's Respiratory Questionnaire (SGRQ) - Pre-bronchodilator FEV1 over 52 weeks compared to placebo - Lung function assessments - Moderate and severe COPD exacerbations - To evaluate safety and tolerability - To evaluate dupilumab systemic exposure and incidence of anti-drug antibodies (ADA)
