Phase I/II Trial of a Malaria Vaccine in Adults Living in the United States of America
A Phase I/IIa Controlled Study of the Safety, Immunogenicity and Preliminary Efficacy of FMP011/AS02A Candidate Malaria Vaccine in Malaria-naive Adults Living in the United States

Phase I/II Trial of a Malaria Vaccine, FMP011/AS01B, in Adults Living in the United States of America.

  • Controlled challenge, Phase I/IIa WRAIR study.
  • Healthy, malaria-naive adults aged 18 - 50 years.
  • 2 groups, 5 subjects in group A (10µg dose) and 15 subjects in group B (50µg dose).
  • Control: none for immunization phase; infectivity controls for challenge and rechallenge phases. Six infectivity controls per day of challenge will be enrolled for the challenge phases, with 3 alternates available for challenge if needed.
  • Vaccination schedule of 0, 1 months.
  • Challenge of up to 15 subjects in Group B.
  • Contingent upon short term efficacy, rechallenge of initially protected subjects 6 months (+/- 2 months) after second dose of vaccine.
  • Self-contained study.
  • Duration of the study, per subject: approximately 15 months (screening, enrollment, vaccination, challenge and rechallenge).
  • Data collection will be by done at the site.
