Phase Ia Study of ChAd63/MVA PvDBP

Summary

This is an open label phase Ia study, to assess the safety of two novel malaria vaccines, ChAd63 PvDBP, with or without MVA PvDBP. Heterologous prime-boost with ChAd63-MVA is, to our knowledge, one of the most potent T cell-inducing subunit vaccine regimens which can importantly also induce antibodies. Previous clinical trials using this regimen expressing ME-TRAP, AMA1 \& MSP1, have shown that administering ChAd63 as a prime followed 8 weeks later by MVA as a boost is a very immunogenic schedule (32-34). For this reason, and to provide comparability with previous ChAd63-MVA trials, we propose to use a similar administration schedule.
