Safety, tolerability and efficacy of PfSPZ Vaccine against heterologous controlled human malaria infection in healthy adults
Objectives
The aim of this study is to determine if individuals living in a non-malaria endemic area such as the United States (US) are protected against heterologous CHMI conducted at these time points.
USSPZV7 is a randomized, phase 1, double-blind, placebo-controlled trial of Sanaria® PfSPZ Vaccine administered on Days 1, 8 and 29 by direct venous inoculation (DVI) to assess safety, tolerability, immunogenicity, and vaccine efficacy (VE) against heterologous controlled human malaria infection (CHMI) with the 7G8 clone of Plasmodium falciparum (Pf) conducted at 3 or 12 weeks after the third immunization.
