5. Study Description
Brief Summary
The aim of this study is to assess whether the protective measures can limit the contaminations by SARS-CoV-2 during the participation in a concert at a non-inferior level to a non-concert / current life situation. A randomized, monocentric, open-label, non-inferiority study comparing, in two phases, a group of volunteers participating in a concert, protected by established protection measures, to a group with no other constraints than national recommendations and obligations (2 concerts, one control group at each concert). Volunteer students, between 18 and 30 years old, at Aix-Marseille University, will be recruited.
Detailed Description
Objectives
Primary objective To assess whether the protective measures implemented (individual protection kit including disposable FFP2 (filtering facepiece) masks, hydro-alcoholic solution, water bottle, disposable tissues, waste bag, physical distancing, flow management and health mediation) make it possible to limit contamination by SARS-CoV-2 during participation in a concert (lasting 2 hours) at a non-inferior level to a non-concert situation
Secondary objectives
To assess whether the protective measures implemented (individual protection kit including disposable FFP2 masks, hydro-alcoholic solution, water bottle, disposable tissues, waste bag, physical distancing, flow management and health mediation) make it possible to limit contamination by other circulating respiratory viruses during participation in a concert (lasting 2 hours) at a non-inferior level to a non-concert situation
To assess whether the protection against viral contamination in the absence of a one-seat gap between 2 volunteers is non-inferior to the protection induced by one-seat gap (sub-group of volunteers)
To assess knowledge, attitudes and practices regarding COVID-19
To assess the level of compliance and adherence to the prevention measures implemented during the concert
To assess SARS-CoV-2 serology prevalence in volunteers
To identify SARS-CoV-2 variants by sequencing SARS-CoV-2 PCR positive cases
Methodology / design A randomized, monocentric, open-label, non-inferiority study comparing, in two phases, a group of volunteers participating in a concert, protected by established protection measures (protection kit, distancing, flow management, health mediation), to a group with no other constraints than national recommendations and obligations (2 concerts, one control group at each concert).
Sample size
4500 participants, in 2 phases: Phase A: Concert A group, n=1125; Control A group, n=1125 Phase B (15 days later): Concert B group, n=1125; Control B group, n=1125
Endpoints
Primary Endpoint:
Conversion of salivary SARS-CoV-2 carriage detected by molecular biology at Day 6 or 7 after each event
Secondary endpoints:
Conversion of salivary carriage of other respiratory viruses detected by molecular biology at Day 6 or 7 after each event
Level of knowledge about COVID-19 and methods of protection
Verbatim from the qualitative interview on knowledge, attitudes and practices
Adherence score for protective measures
Percentage of initially positive SARS-CoV-2 serology in the volunteer sample
Percentages of SARS-CoV-2 variants among positive samples (for each variant)
Intervention
During the music concert (2 hours), prevention measures:
Individual protection kit: disposable FFP2 masks (3), hydro-alcoholic solution, disposable tissues, garbage bag, water bottle
Health mediation, information on barrier measures
Physical distancing (sitting participation)
Person flow management
Statistical Plan
Primary analysis:
The intervention effect will be estimated by the difference in SARS-CoV-2 conversion rates (PCR).
The main non-inferiority analysis will be performed by interval estimation of the difference in PCR SARS-CoV-2 conversion rates, in Per Protocol (each volunteer being associated with the concert or control group according to his or her actual participation), over the 2 concerts (using a multilevel mixed model, with random period effect). An Intention-to-Treat analysis will also be performed.
Secondary analyses:
Analysis of individual knowledge and behavior, and adherence to protection measures (Q1- questionnaire Q1, Q2 and Q3): unsupervised exploratory analyses - classification on principal component analysis
Estimation of the difference in PCR conversion rates (SARS-CoV-2 and other respiratory viruses) adjusted for the level of knowledge and behavior obtained from the questionnaires, for the collective level of protection observed during the concert (ad hoc observations), and for the epidemic situation at the time of the concerts. Estimations will be provided by using a multilevel multivariate logistic model. This approach will eventually allow us to introduce a random period effect to consider the temporality of the measurements. Finally, we analyze the level of the epidemic by IRIS (smallest french geographical area) each week, in collaboration with the ARS-PACA (Health Regional Agency - Agence Regionale de Santé - Provence Alpes Cote d'Azur) and SPF (French National Public Health Agency - Santé Publique France). If necessary, an adjustment on this possible spatial effect will be made, based on the address of the volunteers, to estimate the risk of contamination of the control group (exponential-power variogram)
Serology prevalence will be estimated, and associated behavioral factors will be assessed by using multilevel multivariate logistic regression
Analyses will be performed in Per Protocol and Intent to Treat
A secondary analysis with imputation of missing data will be performed as a sensitivity analysis (after testing the hypothesis of missing at random)
A 5% significance level will be used for decision making, but the probabilities will be interpreted accordingly.
