Measure
AR101
AR101 drug product was supplied in 2 presentations. These were pull-apart capsules containing 0.5, 1, 10, 20 and 100mg of peanut protein and sealed sachets containing 300mg of peanut protein. The capsules were used during the Initial Escalation and Up-dosing phases of the study. The sachets were used during the Maintenance phase.
Placebo
A placebo matching the AR101 drug product was supplied in 2 presentations. These were capsules matching the 0.5, 1, 10, 20 and 100mg peanut capsules but containing no peanut protein, and sealed sachets matching the peanut protein sachets but without any peanut protein. The capsules were used during the Initial Escalation and Up-dosing phases of the study, while the sachets were used during the Maintenance phase.
