This document is intended as a guide to the protocol development for trials of prophylactic vaccines. The template may serve phases I–IV clinical trials protocol development to include safety relevant information as required by the regulatory authorities and as deemed useful by the investigators. This document may also be helpful for future site strengthening efforts.
MEDI-534 is the first live vectored RSV vaccine candidate to be evaluated in seronegative children. It consists of the bovine parainfluenza virus type 3 (PIV3) genome with substituted human PIV3 F and HN glycoproteins engineered to express RSV F protein. A Phase 1 study of 49 healthy RSV and PIV3 seronegative children 6 to <24 months of age demonstrated an acceptable safety profile at the following...
Plasmodium falciparum Liver Stage Antigen 1 (LSA-1) is a pre-erythrocytic stage antigen. Our LSA-1 vaccine candidate is a recombinant protein with full-length C- and N-terminal flanking domains and two of the 17 amino acid repeats from the central repeat region termed “LSA-NRC.” We describe the first Phase I/II study of this recombinant LSA-NRC protein formulated with either the AS01 or AS02 adjuvant...
A Phase 1 trial was conducted in malaria-naïve adults to evaluate the recombinant protein vaccine apical membrane antigen 1-Combination 1 (AMA1-C1) formulated in Montanide ® ISA 720 (SEPPIC, France), a water-in-oil adjuvant. Vaccinations were halted early due to a formulation issue unrelated to stability or potency. Twenty-four subjects (12 in each group) were enrolled and received 5 or 20μg...
Apical Membrane Antigen 1 (AMA1) and Merozoite Surface Protein 1 (MSP1) were produced as a recombinant fusion protein and formulated with the adjuvant Montanide ISA 720 with the aim of replicating the structure present in the parasite protein. A previous trial with this construct demonstrated the vaccine was safe and immunogenic but was associated with injection site reactogenicity. This Phase 1a...
The misery and suffering caused worldwide by infection with the malaria parasite, especially Plasmodium falciparum, has been well documented. Although no licensed vaccine against malaria currently exists, progress has accelerated in recent years towards the goal of developing one. Although the complexity of the malaria parasite has made the malaria vaccine development process tenuous, advances in...
