HIV-1 envelope trimer vaccine induces sex-associated differences in antibody responses: a phase 1 clinical trial.

ABSTRACT: A protective vaccine will be the most powerful instrument to reduce HIV-1 infections worldwide and help bring about a lasting end to the AIDS epidemic. The single centre, randomised, open-label, uncontrolled, phase 1 ACTHIVE-001 clinical trial (NCT03961438) aims to assess the safety and immunogenicity of the ConM SOSIP.v7 native-like trimer protein vaccine, based on an HIV-1 group M consensus sequence, in HIV-negative adults. Twenty-four individuals were enrolled to receive three dosages of ConM SOSIP.v7 protein vaccine in a liposome formulation containing a high dose of the TLR4-agonist MPLA. The primary outcome is vaccine reactogenicity, whereas the main secondary outcome is binding and neutralising antibody responses. Overall, the vaccine is safe and well-tolerated. Furthermore, the vac
