FDA Clinical Hold on BioNTech Malaria Vaccine
FDA has placed a clinical hold on BioNTech’s Phase 1/2a dose escalation clinical trial (NCT06069544) evaluating the safety, tolerability, immunogenicity and efficacy of an investigational RNA-based vaccine (BNT165e) for preventing P. falciparum malaria in healthy malaria-naive adults. The company says the trial is being paused while it takes actions to address the agency’s requests and concerns.
The company describes the multi-antigen malaria vaccine as a “combination of three distinct RNAs, BNT165c and BNT165d (composed of BNT165d1 and BNT165d2), encoding P. falciparum antigens encapsulated in lipid nanoparticles. The BNT165c RNA encodes the full Plasmodium falciparum circumsporozoite protein. The BNT165d1 and BNT165d2 RNAs both encode conserved, immunogenic segments of liver stage-expressed proteins.”
