Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary end point(s): The primary outcome is the area under the HIV RNA curve from treatment interruption (scheduled at week 18 after entering the trial). HIV RNA is determined by the local laboratory using a standard assay. ;Timepoint(s) of evaluation of this end point: The time points for the primary outcome are all weekly visits from week 19 (visit 11) through to week 42 (visit 34). ;Main Objective: The main objective of the study will be to assess the impact of vedolizumab and vaccination with MVA upon viral control following analytic treatment interruption (ATI). ;Secondary Objective: We also plan to undertake a comprehensive analysis of the relationships between a range of biomarkers (including immune responses) and virological control, independent of vedolizumab/vaccination. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary virological outcomes: - Time from treatment interruption (scheduled for 18 weeks after entering the trial) to the earliest of reaching HIV RNA = 100 000 copies/ml (confirmed on a separate sample) or resuming antiretroviral therapy for any reason over a period of 24 weeks - Level of HIV total RNA - First local maximum (peak) level of HIV total RNA during treatment interruption - Rate of increase of HIV total RNA between the last measure below the lower detection limit (LDL) and the first local maximum - Setpoint Secondary safety outcomes: - Grade 3 and worse solicited clinical and laboratory adverse events - Any adverse event leading to interruption in the vaccine/placebo or vedolizumab/placebo schedule - Any event that results in resuming treatment during the ATI - Serious Adverse Events - Other clinical and laboratory adverse events - Change in absolute CD4 - Time to VL suppression after restarting ART ; Timepoint(s) of evaluation of this end point: The time points for the secondary virological outcomes are all weekly visits from week 19 (visit 11) through to week 42 (visit 34). Secondary safety outcomes are assessed at all visits except at week -6 (visit 1). | — |
