Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study contains a phase I component in order to evaluate the local and systemic reactogenicity following the first administration of products in the first 12 participants. The phase I will consist of a slow enrolment of the first 12 participants who will be randomised at a maximum rate of 1 per week for 4 weeks, then 2 per week for 4 weeks before increasing to 4 or more per week. The IDMC will review of cumulative adverse event data through to and including the first safety visit in the 12th participant and their recommendation will be sought with regard to expanding recruitment.
The phase II component will assess the effectiveness and safety of the three experimental strategies upon viral control following analytic treatment interruption (ATI). The phase II component is divided into two stages, an interim efficacy stage and a final efficacy stage. There will be a pause in enrolment after 88 participants have been enrolled. A planned interim review by the IDMC at the end of the first stage will provide an opportunity to modify the design of subsequent stages or the recruitment strategy.
Screening will take place during the 6 weeks prior to randomisation. Eligible participants will be enrolled at week 0 and randomised to vaccine, vedolizumab, the combination of vaccine and vedolizumab or matched placebos. Participants and study staff will be aware of the schedule the participant is randomised to, with a third allocated to injections, a third to infusions and a third to the combination of injections and infusions. Only staff authorised to prepare the products will know who is randomised to active product or placebo within each schedule in a ratio of 3:1 respectively.
The vaccine regimen will start at week 0 and the vedolizumab regimen at week 2, each with matched placebo.
Participants will continue on cART during the first 24 weeks covering the vaccination period and 5 of 6 vedolizumab/placebo infusions.
Treatment will then be interrupted and resumed when the viral load is confirmed to have rebounded to ≥10,000 copies/ml, or the CD4 falls to ≤350 cells/mm3, or there is evidence of disease progression, or they have completed 24 weeks of treatment interruption.
