A Study to Determine the Effects of an Investigational Malaria Vaccine Given to Adults Living in the United States and Thereafter to Adults Living in Kenya

Malaria Clinical Trial

Official title:
Phase 1a Open-label Dose Escalation Study to Evaluate the Safety, Reactogenicity, and Immunogenicity of the Candidate Plasmodium Falciparum Malaria Protein 010 (FMP010) Administered Intramuscularly With GSK Biologicals' Adjuvant AS01B in Healthy Malaria-Naïve Adults

Clinical Trial Summary

The purpose of this study is to determine whether an investigational malaria vaccine is safe and induces an immune response against malaria when tested in adults living in the United States.

Clinical Trial Description

The study begins with the US phase in which 26 volunteers aged 18 to 50 years will be enrolled to receive an investigational malaria vaccine. The vaccine is made of a malaria protein FMP010 mixed in the adjuvant AS01B. Since this vaccine has not yet been in humans, first, 5 volunteers will get a small (10 µg) dose of FMP010 in AS01B. If it is safe, then 20 volunteers will get 50 µg FMP010 in AS01B. Vaccinations are given IM in the deltoid of the non-dominant arm, every month for 3 months. After each vaccination, the subjects will follow up at clinical trials for evaluation of any adverse events. There will be blood draws to assess safety of the vaccine as well as the level of immune response generated to the vaccine.

Upon receipt of preliminary safety results, the Kenya phase begins in which 30 volunteers who are randomized to receive either 50 µg FMP010 in AS01B (20) or the rabies vaccine (10). Vaccination and is on the same schedule as in the US phase and follow-up is for 112 days. ;
