A randomised controlled trial of adjunct corticosteroid therapy in hospitalised children with community acquired pneumonia (CAP): THE KIDS-STEP STUDY Investigator initiated clinical trials (IICT)

Research Project  | 3 Project Members

Community-acquired pneumonia (CAP) is a common reason for hospitalisation in childhood and represents a considerable socioeconomic burden. In hospitalised adults with CAP, we have shown a beneficial effect of short-term steroid treatment on time to clinical stability and on duration of hospital stay in a randomised controlled trial (RCT). These benefits in adults with CAP have been confirmed in a recent meta-analysis and appear to be independent of the aetiology of CAP. It is unclear if adjunct steroid treatment benefits children with CAP.Rationale: An intervention that shortens time to stability and discharge in childhood CAP would carry substantial socioeconomic benefits in terms of healthcare resource utilization as well as parental and child absenteeism from work and out-of-home activities, respectively. Based on our findings in adult patients with CAP, we expect a positive clinical effect of steroids also in children. So far, no large-scale RCTs have evaluated the effectiveness of oral steroids on patient-relevant or clinically relevant endpoints in childhood CAP. In particular, it is unclear whether clinical improvement in the short-term is offset by a mid-term increase in CAP recurrence. Aim of the study: The overall aim of the trial is to evaluate the impact of oral steroid treatment in children with CAP on outcomes that are of high importance for patients. Specifically, we aim to concurrently assess the effect of adjunct oral steroids in children hospitalised for CAP on clinical stability (efficacy) and CAP recurrence (safety).Objectives: The primary objective is to concurrently evaluate (i) whether treatment of children hospitalised for CAP with oral betamethasone is superior to placebo for clinical stability (defined as resolution of vital sign abnormalities in room air) within 48 hours of hospitalization; (ii) whether treatment of children hospitalised for CAP with oral betamethasone is noninferior to placebo for CAP-related readmissions to hospital within 28 days of randomisation. Other objectives include the evaluation of effects of oral betamethasone treatment (versus placebo) in children hospitalised for CAP on: duration of hospital stay; severity and duration of CAP symptoms; parental absence from work and/or child absence from routine out-of-home care or school; overall duration of antibiotic exposure and inpatient days; intensive care unit admissions; mortality; rate and severity of solicited clinical side effects and serious adverse events. Exploratory subgroup analyses are planned to evaluate the effect of age, initial antibiotic treatment, respiratory pathogen detected in initial nasopharyngeal swab and radiological evidence of CAP. Study Design: We propose a pragmatic randomised, controlled, patient-, care-giver-, investigator- and outcome-assessor blinded multicentre trial in 8 Swiss paediatric departments with two parallel groups (one active, one control; 1:1 ratio). Preschool and school-age children with moderate to severe CAP (defined clinically) requiring admission to hospital will be included. 700 patients will be randomised 1:1 to receive betamethasone (Betnesol®) (active group: 0.2 mg/kg/d in 1 daily dose for 2 days; control group: 2 days of placebo). The co-primary endpoints will be (i) the proportion of children who are clinically stable within 48 hours of randomisation; the proportion of children requiring CAP-related readmission to hospital within 28 days of randomisation. Significance: Any treatment associated with an increased likelihood of early clinical stability may lead to a higher proportion of children suitable for prompt discharge, in turn reducing the patient-relevant outcome of length of stay. This would likely lead to changes in paediatric CAP management in Switzerland (and similar high-income settings), especially if recurrence of moderate-severe CAP remained demonstrably low.

Blueprint for Global Vaccine Safety

Research Project  | 1 Project Members

WHO contract, SPHQ09- LOA-117 Activity 1.1 Survey of global vaccine safety stakeholders Perform a standardized survey among ministries of health, regulatory authorities, professional organizations, academic institutions and vaccine manufacturers. This qualitative survey will: a. Develop standardized questionnaire (Consultant with Working Group). b. Define selection criteria for survey recipients (Consultant with Collaborative Group). c. Develop the background document for interviewees (Consultant). d. Implement survey (Consultant). e. Analyse data (Consultant). f. Draft report (Consultant with Collaborative Group). g. Review the report (Project Advisory Committee). h. Finalize the report (Consultant with Collaborative Group). Activity 1.2 Report on Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis of ongoing global and inter-country vaccine safety initiatives Description and assumptions: Several international projects designed to improve vaccine safety monitoring are ongoing, those projects are referred to in the proposal as "vaccine safety initiatives". There is, however, only limited understanding of the impact these initiatives currently have in the poorest countries. The purpose of the SWOT analysis is to describe the current structure and accomplishments of 10-15 of the most important of those initiatives and determine how these organizations can best serve the needs of the global effort, and propose roles and responsibilities. This analysis will be performed by a working group developing a set of criteria characterizing the strengths, weaknesses, opportunities and threats of 10 to 15 international vaccine safety initiatives. The initiatives that will be selected will have been identified through the survey from Activity 1.1 and will satisfy to explicit criteria of global relevance and previous accomplishments. This analysis will also consider the performance of WHO and UNICEF networks. SWOT questionnaires will be structured around the mission, expertise available, geographic reach, type of support provided, resources available and future prospects. Data collected will be analyzed to describe the level of impact for each dimension of coutries vaccine safety work and to identify the main gaps with respect to the currently available external support to country activities. Activities: 1. Develop the analytical criteria (Consultant with Collaborative Group). 2. Define selection criteria and identify the 10-15 most relevant initiatives (Consultant with Collaborative Group). 3. Survey the selected initiatives (Consultant). 4. Analyze the data through a working group (Consultant and Project Consultative Committee). 5. Draft the report Consultant. 6. Review of the report (Project Consultative Committee). 7. Finalize the report (Consultant with Collaborative Group).

INYVAX - Optimisation of the development of poverty related diseases (PRD) vaccines by a transversal approach, addressing common gaps and challenges

Research Project  | 1 Project Members

A number of new vaccines are being developed against poverty-related infectious diseases of major public health importance at a global level. The development of these vaccines is facing the same kind of challenges and gaps, which still prevent: the establishment of readily accessible formulation and scale-up process development capacity for neglected disease vaccines. the establishment of a systematic approach for prioritising formulation of vaccine candidates using accepted pre-clinical criteria. the development of information-sharing tools to strengthen connections between the scientists, the developers and the clinical investigators. To address those challenges, the European vaccine community needs to establish a shared vision and goals and to identify the activities that could address some of the above-mentioned challenges. A cooperation between the different groups of PRD vaccine developers will bring innovative approaches for accelerating the development of effective vaccines. Among those challenges, several can be addressed through coordination across poverty related diseases, such as: Difficulties in accessing some technology platforms, such as synthetic peptides/recombinant proteins and expertise for GMP development, therefore allowing rational decisions to be made on the best industrial approach for pharmaceutical development. Difficulties in accessing certain know-how, such as lyophilisation and lack of formulation platforms accessible to academic groups. Difficulties in accessing some delivery platforms, such as adjuvants and virus-like particles for GMP development and/or to assess the quality and regulatory compliance of those platforms. Difficulties in harmonising the safety data collection. The insufficient number of trained scientists able to undertake leadership roles in vaccine development.
