TRIAL DESCRIPTION
Public title A study on the safety, reactogenicity, and immune response to the invasive nontyphoidal Salmonella-generalized modules for membrane antigens (iNTS-GMMA) vaccine against invasive nontyphoidal Salmonella in adults, children, and infants
Official scientific title A Phase IIa observer-blind, randomized, controlled, age-de-escalation, single center interventional study to evaluate the safety, reactogenicity, and immune response of the invasive nontyphoidal Salmonella vaccine against S. Typhimurium and S. Enteritidis, in adults, children and infants, including dose-finding in infants, in Africa
Brief summary describing the background and objectives of the trial Non-typhoidal Salmonella (NTS), such as S. Enteritidis and S. Typhimurium can cause an invasive syndrome with bacteremia, high fevers and metastatic infection which if untreated can lead to septicemia and death. Infection with iNTS has been reported in sSA since the 1980s as a cause of child febrile illness and bacteremia, but often misdiagnosed as malaria [Feasey, 2012]. The number of cases per year were estimated around 535 000 in 2017, of which >400 000 were in sSA [Collaborators GBDN-TSID, 2019]. An estimated 59 100 iNTS deaths with more than half of them in children <5 years of age and a 14.5% case fatality rate have been reported in 2017 [Collaborators GBDN-TSID, 2019]. The iNTS disease causative agents are associated with increasing antimicrobial resistance (AMR) and are classified by the World Health Organization (WHO) as high priority pathogens for developing new antibiotics. The most common African S. enterica serovars associated with iNTS disease are S. Enteritidis and S. Typhimurium, accounting for >90% of iNTS cases in sSA [Reddy 2010]. There is no licensed human vaccine against iNTS. The purpose of this study is to evaluate the safety, reactogenicity, and immune response of the GlaxoSmithKline (GSK) Vaccines Institute for Global Health (GVGH) invasive nontyphoidal Salmonella-generalized modules for membrane antigens (iNTS-GMMA) candidate vaccine against S. Typhimurium and S. Enteritidis with an age de escalation and dose escalation approach, in African adults (18–50 years of age), children (24–59 months of age) and infants (9 months and 6 weeks of age). All age groups will be randomized to receive either the iNTS-GMMA candidate vaccine or a placebo (adults only) or a control vaccine (GSK’s combined meningococcal groups A, C, Y and W-135 [MenACWY] conjugate vaccine, or GSK’s diphtheria [D], tetanus [T], pertussis [Pa], hepatitis B [HBV], poliomyelitis [IPV] and Haemophilus influenzae type b [Hib] [DTPa-HBV-IPV+Hib] vaccine).
