A Study on the Immune Response and Safety of a Multicomponent Shigella Vaccine in Preventing Shigellosis in Infants

This study evaluates the immune response and safety of a multicomponent, 2-dose Shigella vaccine in preventing shigellosis in African infants. The candidate vaccine, altSonflex1-2-3, is currently being evaluated in a Phase 2 age de-escalation (from least vulnerable adult population to most vulnerable paediatric population) clinical study in Kenya, with the aim of identifying a preferred dose, using a 3-dose vaccination schedule in infants from 9 months of age (NCT05073003). This Phase 2 clinical study will evaluate the safety and immunogenicity of an alternative 2-dose vaccination schedule.

Racecadotril Versus Standard Treatment in Decreasing the Duration of Acute Diarrhoea in Children

Acute watery diarrhea is defined as the passage of 3 or more loose or liquid stools per day for 3 or more days but less than 14 days, including patients with mild to moderate dehydration per WHO classification. The study's outcome variables are stool frequency, measured by the total number of stools passed during 24 and 48 hours from the initiation of treatment, and hospital duration, measured by the total duration of hospital stay in hours. The null hypothesis states that racecadotril combined with standard treatment has no effect on reducing the mean number of stools passed during 48 hours compared to standard treatment alone in pediatric patients with acute watery diarrhea, while the alternate hypothesis suggests that racecadotril combined with standard treatment will significantly reduce the mean number of stools passed during 48 hours compared to standard treatment alone in these patients.

A Study on the Safety and Immune Responses to the GVGH altSonflex1-2-3 Vaccine Against Shigellosis in Adults, Children, and Infants

The aim of the current clinical study was to evaluate, for the first time in humans (FTIH), the safety and immunogenicity of the altSonflex1-2-3 candidate vaccine against S. sonnei and S. flexneri serotypes 1b, 2a, and 3a. The vaccine was first administered to adults 18 to 50 years of age in Europe. Subsequently, the vaccine was administered to a shigellosis-endemic population in Africa, first to adults 18 to 50 years of age, then to children 24 to 59 months of age, and finally to infants 9 months of age. Infants also received a third vaccination. Three different doses of the vaccine \[low, medium, and high amounts of antigen\] were evaluated using an age de-escalation approach (from the least vulnerable adult population to the most vulnerable paediatric population). The results of this study allowed the selection of the most appropriate dose for further vaccine development in infants 9 months of age, which was the main target age group for this vaccine.

A Study Based on Medical Records in Spain That Looks at Diarrhoea Control in People With Pulmonary Fibrosis Who Are Taking Nintedanib

This is an observational, non-interventional, and prospective post authorization safety study (PASS) that will describe the real-world proportion of patients that achieve nintedanib-associated diarrhoea control after 12 weeks of follow-up, in hospital settings in Spain. It will include outpatients (i.e., those attending ambulatory visits) with interstitial lung diseases (IPF) and other progressive pulmonary fibrosis (PPF) treated with nintedanib (150 mg bid) and having a first episode of diarrhoea after nintedanib initiation.

Long-Term Immunogenicity of the altSonflex1-2-3 Shigella Vaccine in African Children

The current study is a follow-up to 2 previous parent studies, a dose-selection study with 3 different dose-levels of the altSonflex1-2-3 vaccine in a schedule of 3 vaccinations (H06\_01TP study \[NCT05073003, 212149\]) and a study with an alternate 2 vaccination schedule H06\_02TP study \[NCT06663436, 219449\]). The current study aims to assess the longevity of the immune response to the selected dose of the altSonflex1-2-3 vaccine 1, 2, and 3 years after the last vaccination in African children. The study involves no new vaccinations but will collect immunogenicity blood samples from participants.

CMTS4520 for Chronic Diarrhoea in Adults

This is a randomized controlled trial to explore the efficacy and safety of CMTS4520 (Dietary Fiber Probiotics) for patients with chronic diarrhoea.
