ConM SOSIP.v7 gp140, adjuvanted with MPLA liposomes(AMC-UvA)

ACTHIVE-001 is a randomised, open-label, uncontrolled phase 1 clinical trial to determine the safety profile of the native-like HIV-1 envelope vaccine, ConM SOSIP.v7, adjuvanted with monophosphoryl lipid A (MPLA) liposomes. The study will furthermore determine the extent to which the vaccine influences the breadth of viruses neutralised by induced antibodies and the associated diversity of B and T cell responses.
The research will also investigate the effect of a within-schedule successive dose level reduction (i.e. fractional dose boosting), aimed to induce higher levels of somatic hypermutation and broadly neutralising antibodies. The primary outcome will be measurement of adverse events. Secondary and exploratory outcomes will include specific viral neutralisation activity of serum antibodies and characterisation of antigen specific blood and lymph node B and T cell responses.
