Salmonella Infections Clinical Trial
Official 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 GVGH iNTS Vaccine Against S. Typhimurium and S. Enteritidis, in Adults, Children and Infants, Including Dose-finding in Infants, in Africa
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 population, starting with adults (18-50 years of age), then on children (24-59 months of age) and finally to infants (9 months and 6 weeks of age). Infants are the target for primary vaccination from 6 weeks of age.
The study will be conducted in two stages: Stage 1: Age De-escalation from Adults to Children and Infants - Adult participants will receive either iNTS-GMMA Dose C (high) or a control vaccine intramuscularly on Day 1 and Day 57. - Child participants will receive either Dose B (medium) or Dose C (high) of the candidate vaccine or the control on Day 1 and Day 57. - Infant participants (9 months of age) will receive either Dose A (low), Dose B (medium), or Dose C (high) of the candidate vaccine or the control on Day 1, Day 85, and Day 169. - Infant participants (6 weeks of age) will receive either Dose A (low), Dose B (medium), or Dose C (high) of the candidate vaccine or the control on Day 1, Day 85 (Priming phase), and Day 232 (Booster phase). Stage 2: Dose-finding in Infants of 6 weeks of age -Infants (6 weeks of age) will receive one of the three dose levels (Dose A [low], Dose B [medium], or Dose C [high]) of the candidate vaccine or the control on Day 1, Day 85 (Priming phase), and Day 232 (Booster phase). ;
