In June 2013, under the aegis of the French Life Sciences and Healthcare Alliance (AVIESAN), France launched a consortium called REACTing: REsearch and ACTion targeting emerging infectious diseases. REACTing (https://reacting.inserm.fr/) is coordinated by Prof. Yazdan Yazdanpanah (Lévy Y, Yazdanpanah Y, Delfraissy JF. Lancet 2016).
REACTing is a multidisciplinary approach bringing together excellent teams and laboratories, in order to prepare and coordinate research to deal with a threat that hasn’t happened yet and that is therefore, by definition, unforeseeable.
This consortium is organised around a steering committee of some fifteen human and animal health specialists; it relies on an 8-member scientific committee and a methodology centre. REACTing does not target any particular disease, and can get involved in all emerging infectious diseases. It has a broad scope, ranging from basic research to the human and social sciences, including environmental sciences, epidemiology and public health. The approach is broad-based and multidisciplinary, because we know that health crises are always complex phenomena in both their causes and their effects.
REACTing has two objectives:
- To improve research planning during periods between crises (peace time): governance, preparation of research tools, identification of research priorities, application for funding, and preparation of ethical and legal aspects essential to preparing for research projects to be set up in an emergency ;
- To coordinate, fund and establish research projects during periods of epidemic crisis: coordination, scientific and strategic priorities, methodological assistance, and informing the authorities and general public.
This consortium gained international visibility through its actions during the epidemic of Ebola and Zika, in particular (https://reacting.inserm.fr/)

Clinical trials in which the REACTing Methodology Center is involved (methodological and logistical support for the implementation, monitoring and analysis of projects)
I) ARBOVIROSES projects
CARBO cohort of patients suffering acute arbovirus infection (Pr André Cabié, sponsor: CHU Fort de France).
This cohort allows to follow and characterize diseases such as Dengue, Chikungunya and Zika virus infection and any other arbovirus that might emerge in the West Indies (Guadeloupe and Martinique), French Guiana (Cayenne) or Metropolitan France.
ARBHITA (Dr Sylvie Abel, sponsor: CHU Fort de France) is an ancillary study of CARBO whose methodology and statistical analyzes are under the responsibility of REACTing Methodology Center.
The aim of this study is to describe precisely the natural history of arbovirus infection by analyzing the evolution of several biomarkers in a limited number of patients included in the CARBO cohort.
The data collected have great scientific value (description of viral kinetics and antibodies and establishes a very complete biological collection: venous and capillary blood, urine, stools, tears, pharyngeal secretions, saliva, sperm, vaginal secretions, milk).
CHIKIVIG-01 (Pr Bruno Hoen, sponsor: CHU Pointe à Pitre) is a therapeutic trial (« Prevention of Chikungunya Infection in Neonates: Clinical Evaluation of Anti-CHIKV Hyperimmune Intravenous Immunoglobulins »).
The investigators hypothesize that the administration of anti-CHIKV hyperimmune human intravenous immunoglobulins to neonates exposed to a high risk of severe form of Chikungunya infection is safe enough to justify its evaluation in an open non randomized trial aimed to confirm the safety and preliminary assess the efficacy of this intervention.
ZIKA-DFA (Pr Bruno Hoen, CHU Pointe à Pitre, sponsor: INSERM)
The Zika epidemic has spread into the three French Overseas Departments in the Caribbean (DFAs) in 2016.
This prospective observational, non-interventional study is meant to collect, within usual care practices, clinical and paraclinical information which will allow the precise description of the consequences of ZIKV infection occurring during pregnancy.
This study has 2 arms:
- Zika Virus Infection’s Neonatal and Pediatric Consequences in French Department of America (ZIKA-DFA-BB)
- Zika Virus Infection’s Pregnancy Consequences in French Department of America (ZIKA-DFA-FE)
ZIKA-DFA-BB : https://clinicaltrials.gov/show/NCT02810210
ZIKA-DFA-FE : https://clinicaltrials.gov/show/NCT02916732
II) EBOLA projects
JIKI trial (Pr Denis Malvy, CHU Bordeaux, sponsor: INSERM) «Efficacy of Favipiravir in Reducing Mortality in Individuals With Ebola Virus Disease in Guinea ».
The REACTing Methodology Center collaborated with a team of researchers in Bordeaux to develop and implement the JIKI trial. The REACTing Methodology Center was responsible for the statistical analyzes. The results were published « Experimental Treatment with Favipiravir for Ebola Virus diseases (the JIKI Trial): A Historically controlled, single-arm proof-of- Concept Trial in Guinea » Plos Med ; Mars 2016. These first results open up possibilities in the treatment of this disease.
FORCE trial (Dr Daouda Sissoko, CHU Bordeaux, sponsor: INSERM) «Tolerance and Activity Evaluation of High Doses of Favipiravir Against Ebola Virus in the Semen ».
This study aims to evaluate favipiravir high dose tolerance in male survivor of Ebola Virus Disease (EVD) with Ebola Virus (EBOV) RNA in semen. This is a dose escalation study with 3 cohorts of 6 patients, each dose level including 2 sentinel patients.
The REACTing Methodology Center was responsible for the statistical analyzes.
