OMEGA Study: A Study of the Safety and Feasibility of Up-titration With INT301 in Adults With Sensitivity to Peanut

Oral Mucosal Escalation Goal Assessment (OMEGA) Study: A Randomized Placebo-Controlled Phase 1 Study of the Safety and Feasibility of Up-titration With INT301 in Adults With Sensitivity to Peanut

This is a phase 1, multi-center, randomized, double-blind, placebo-controlled study in adult participants with peanut allergy. Participants will be randomized in a 3:1 ratio to receive either an escalating dose of INT301 or placebo. The treatment group will be blinded to the investigator, participants, and the Intrommune study team.

Inclusion Criteria:

Participant must be 18-55 years of age inclusive, at the time of signing the informed consent.

Female participants of childbearing potential or male participants with female partners of child-bearing potential must utilize highly effective birth control method(s) throughout the study and for 30 days after the final dose of study drug. Acceptable methods of contraception include: complete abstinence, male or female condoms with spermicide, oral or implanted contraceptives, or vasectomy.

For female participants of child-bearing potential: Negative serum beta human chorionic gonadotrophin (HCG) pregnancy test at screening.

Capable of giving signed informed consent as described in Appendix 1 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.

Meets at least one of the following conditions

• Positive skin prick test (SPT) (wheal at least 3 mm greater than control) AND/OR Peanut specific IgE >0.35 kU/L
• Convincing clinical history of allergic reaction to peanut within 1 hour of ingestion for at least 3 months prior to screening.
• Failed an oral food challenge (OFC) of < 100mg of peanut protein at screening.
• Participant willing and able to undergo the procedures required by the protocol, including, assessment completion, protocol compliance, and participation in the placebo dosing period(s).

Exclusion Criteria:

• History of severe anaphylaxis to peanut, defined as hypoxia, hypotension, or neurologic compromise (cyanosis or oxygen saturations < 92% at any stage, hypotension, confusion, collapse, loss of consciousness, or incontinence)

• Significant medical condition (e.g., liver, kidney, gastrointestinal, cardiovascular, hematologic, or pulmonary disease) which would make the subject unsuitable for induction of food reactions

• Eosinophilic or other inflammatory (e.g. celiac) gastrointestinal disease

• Psychiatric disorders that the Investigator believes will interfere with study assessments

• Uncontrolled asthma, defined by at least one of the following conditions:

  • - FEV1 <80% of predicted, or ratio of FEV1 to forced vital capacity (FEV1/FVC) <75% of predicted, with or without controller medications.
  • - Inhaled corticosteroids (ICS) dosing of >500mcg daily fluticasone (or equivalent ICS based on NHLBI dosing chart.
  • - One hospitalization in the past year for asthma
  • - An ER visit for asthma within six months prior to screening

• Planned dental surgery during from screening until study exit

• Moderate or advanced periodontal disease.

• Current pregnancy or lactating
