DBV announces additional Phase I data in pertussis toxin study


DBV Technologies, the Geneva University Hospitals and BioNet-Asia presented new data from a Phase I study evaluating the safety and immunogenicity of boosting young adults against pertussis toxin with an investigational epicutaneous patch containing recombinant PT.
