Brief Summary:
The purpose of this study is to demonstrate the safety, tolerability, and efficacy of AR101 through characterized oral desensitization immunotherapy (CODIT) in peanut-allergic children and adults who have completed the ARC003 study.

Condition or disease Intervention/treatment Phase
Peanut Allergy Biological: AR101 Phase 3

Detailed Description:
This is an international, multicenter, open-label, 2-arm follow-on study of the safety, tolerability, and efficacy of AR101 in peanut-allergic individuals who have completed the ARC003 study. This study will explore alternative dosing regimens during extended maintenance with AR101.

Arm Intervention/treatment
Group 1 (Placebo Crossovers)
Subjects who complete the placebo arm of ARC003 and consent to enroll in ARC004 (Group-1) will cross over to active treatment with AR101 using the same dosing regimen used in ARC003 in open-label fashion. Group 1 subjects may also be assigned to cohorts which test the gradual lengthening of dosing intervals. Following the completion of their longest tested dosing interval, Group 1 subjects will undergo an exit double-blinded placebo-controlled food challenge (DBPCFC).
Biological: AR101
AR101 powder provided in capsules & sachets

Group 2 (Active Rollovers)
Subjects who successfully complete the active arm of ARC003 and consent to enroll in ARC004 (Group-2) will consecutively enter treatment with AR101 in one of three cohorts which will test alternate dosing intervals. There will be a DBPCFC at the completion of the subject's longest tested dosing interval.
Biological: AR101
AR101 powder provided in capsules & sachets

Primary Outcome Measures :
  1. Incidence of adverse events including serious adverse events (Safety and Tolerability) [ Time Frame: 38 months ]
    The frequency of treatment-related adverse events and serious adverse events during the overall study period
