Study summary

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

Read the 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.

Eligibility criteria

Key Inclusion Criteria:

  • Completion of the ARC003 study
  • Written and/or assent from subjects/guardians as appropriate
  • Use of effective by sexually active female subjects of

Key Exclusion Criteria:

  • Early discontinuation from the ARC003 study
  • Meets any longitudinally applicable ARC003 study exclusion criteria
  • (Group 2 only) Failure to tolerate ≥ 443 mg cumulative of peanut protein with no or mild symptoms in the ARC003 study Exit DBPCFC
  • Any other condition that, in the opinion of the Investigator, precludes participation for reasons of safety
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Study arms

  • Other
    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

  • Other
    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

What researchers measure

Primary outcomes

  1. Percentage of Subjects Ages 4-17 With Treatment-related Adverse Events (TEAE)

    Percentage of subjects ages 4-17 with at-least 1 TEAE, including serious adverse events, during the overall study period. The percentage of subjects reporting at least 1 TEAE by maximum reported severity is also presented using the 5-point CTCAE severity grading scale. All safety evaluations were conducted using the safety population (all subjects who received at least 1 dose of AR101 during ARC004), age 4-17 years. Safety data are presented for group 1 (former placebo) and Group 2 data are divided into columns for cohort 1 (QD), cohort 2 (overall), cohort 3A (QD), and cohorts 3B and 3C (overall).

    Time frame: Up to 126 weeks

Secondary outcomes

  1. Percentage of Subjects Ages 4-17 Responding to Each Challenge Dose at Exit DBPCFC (Double-blind, Placebo-controlled Food Challenge)

    The percentage of subjects who tolerated each the of 300 mg, 600 mg, 1000 mg, or 2000 mg challenge doses with no more than mild symptoms at exit DBPCFC. Analyses based on DBPCFCs used the completer population (age 4-17 years).

    Time frame: Up to 126 weeks
