NCT ID: NCT03292484

Last Updated: 2024-12-19

Results Overview

An AE was any untoward medical occurrence in humans, whether or not considered related to the investigational product (IP), that occurred during the conduct of a clinical study. A SAE was any event that resulted in any of the following: death, life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, congenital abnormality or birth defect, or important medical event that did not result in one of the above outcomes, but jeopardized the health of the study participant or required medical or surgical intervention to prevent one of the outcomes listed above. TEAEs were defined as those AEs with onset after the first dose of AR101 in ARC008 and no more than 30 days after the last dose of study drug.

Participant Flow

This Phase 3, open-label study was conducted in participants who participated in a prior AR101 study at 89 investigational sites in 10 countries (Canada, France, Germany, Ireland, Italy, Netherlands, Spain, Sweden, United Kingdom, and the United States).

A total of 911 participants were enrolled in this study. After enrolling in ARC008, all participants received or continued initial dose escalation, up-dosing, and maintenance of AR101 at 300 milligrams (mg) per day.

Population: The safety population consisted of all participants who received AR101 during ARC008. Only those participants who had an OLFC or a DBPCFC are reported.

The maximum tolerated challenge dose for a food challenge was defined as the maximum single dose of peanut protein resulting in no more than mild symptoms and assessed by the investigator to have been tolerated (i.e., the participant did not experience any dose-limiting symptoms). During the OLFC, single doses (300, 600, 1000, and 2000 mg) of peanut protein were conditionally tested using a food challenge mixture administered sequentially at 20- to 30-minute intervals. During the DBPCFC, single doses (3, 10, 30, 100, 300, 600, 1000, and 2000 mg) of peanut protein and placebo were conditionally tested using a food challenge mixture administered sequentially at 20- to 30-minute intervals up to a single highest challenge dose of 2000 mg.
