A Lassa Fever Vaccine Trial in Adults and Children Residing in West Africa : A Phase 2 Randomized, Double-Blinded, Placebo-Controlled Clinical Trial to Evaluate the Safety, Tolerability, and Immunogenicity of rVSV∆G-LASV-GPC Vaccine in Adults and Children Residing in West Africa
rVSVΔG-LASV-GPC is a candidate vaccine that has been shown to be safe and protects against LF disease in animals. The vaccine is now being studied in an ongoing Phase 1 trial and has to date been well tolerated and immunogenic. This Phase 2 trial will add to data from the Phase 1 trial to establish a broader profile of safety and immunogenicity in adults and expand the population to include a subset of adults with HIV infection as well as older adults and healthy children, in preparation for an efficacy trial in West Africa. Primary Objective: • To evaluate the safety and tolerability of rVSVΔG-LASV-GPC vaccine at 2 different dosage levels in adults, including PLWH, and in children Secondary Objectives: • To determine binding LASV-GPC-specific antibody responses induced by rVSVΔG-LASV-GPC vaccine • To determine neutralizing LASV-GPC-specific antibody responses induced by rVSVΔG-LASV-GPC vaccine in a subset of participants in each group • To evaluate the magnitude and duration of the rVSVΔG-LASV-GPC vaccine viremia in plasma in a subset of participants. • To evaluate the magnitude and duration of the rVSVΔG-LASV-GPC vaccine shedding in saliva and urine, and possibly semen and cervicovaginal fluid, in a subset of participants Exploratory Objective • To explore the characteristics of the immune responses induced by rVSVΔG-LASV-GPC vaccine in a subset of participants.
