An Exploratory Phase I, Randomized, Observer-blind, Placebo-controlled Dose Escalation Trial Evaluating the Safety, Tolerability and Immunogenicity of an Investigational RNA-based Vaccine for Active Immunization Against Malaria

BioNTech SE·interventional·Posted Oct 14, 2022·Updated Sep 3, 2025

In Brief

A Phase 1 clinical trial evaluating BNT165b1 and Placebo for Malaria. Completed, enrolled 60 participants across 5 sites.

Detailed Summary

This first-in-human clinical trial, was a dose escalation multi-center trial designed to assess the safety, tolerability, and immunogenicity of the vaccine component, BNT165b1, a ribonucleic acid (RNA)-lipid nanoparticle (LNP) encoding for part of the Plasmodium falciparum circumsporozoite protein (PfCSP). BNT165b1 was evaluated at three dose levels (DLs) to select a safe and tolerable dose in a 3-dose schedule.
