Female subject must either:
- Be of non-childbearing potential, clearly premenarchal; documented surgically sterile (e.g., hysterectomy, bilateral salpingectomy, bilateral oophorectomy).
- Or, if of childbearing potential, agrees not to try to become pregnant during the study; and have a negative urine pregnancy test at screening and at day 1 (predose); and if heterosexually active, agrees to consistently use 1 form of highly effective birth control starting at screening and throughout the study period.
- Female subject must agree not to breastfeed starting at screening and throughout the study period, and for 28 days after the final study drug administration.
- Female subject must not donate ova starting at screening and throughout the study period, and for 28 days after the final study drug administration.
A heterosexually active male subject with female partner(s) who are of childbearing potential is eligible if:
- Agrees to use a male condom starting at screening and continue throughout study treatment and for 28 days after the final study drug administration. If the male subject has not had a vasectomy or is not sterile, the subjects female partner(s) is utilizing 1 form of highly effective birth control starting at screening and continue throughout study treatment and for 90 days after the male subject receives his final study drug administration.
- Male subject must not donate sperm starting at screening and throughout the study period, and for 90 days after the final drug administration.
- Subject and subject's parent(s) or legal guardian agree that the subject will not participate in another interventional study while participating in the present study.
Exclusion Criteria:
- Subject has severe anaphylaxis to peanuts (Grades 4 or 5 including dyspnea associated with hypoxia, cyanosis, hypotension or neurological compromise) per the Grading of Food-Induced Anaphylaxis According to Severity of Clinical Symptoms based on historical clinical symptoms.
- Subject develops a Grade 4 or 5 reaction during the DBPCFC, per the Grading of Food- Induced Anaphylaxis According to Severity of Clinical Symptoms based on historical clinical symptoms.
- Subject has received or is planning to receive administration of any vaccine (other than injectable Influenza vaccine) from 28 days prior to the first dose through 2 weeks after the last dose of the study vaccine.
- Subject received any specific immunotherapy for allergy (e.g., epicutaneous immunotherapy [EPIT], sublingual immunotherapy [SLIT], Subcutaneous immunotherapy [SCIT] and oral immunotherapy [OIT]) during the past 12 months, currently or plans to receive during the course of the study.
Subject has used the following drug(s) prior to the dosing of the study vaccine:
- Within 2 months prior to study vaccine administration: Systemic (or inhaled) steroid, chemical mediator-isolation inhibitor, T helper cell type 2 (Th2) cytokine inhibitor, thromboxane A2 synthesis inhibitor, thromboxane A2 receptor antagonist, β-blocker, angiotensin-converting enzyme inhibitors and/or angiotensin-receptor blockers
- Within 3 months prior to study vaccine administration: Biologics and/or immune modulators (including anti-TNFα antibody and anti-IgE monoclonal antibody)
- Subject has history of allergic reactions such as anaphylactic shock, angioedema with airway constriction or hypotension caused by food other than peanut and/or medical products (including vaccine) in the past.
- Subject's laboratory test results at screening or prior to study drug dosing on day 1 are outside the normal limits and are considered clinically significant.
- Subjects with anti-Lysosomal associated membrane protein (LAMP)-1 antibodies above the cut-point for the Tier 1 assay and who are confirmed positive in the Tier 2 assay at Screen 1 visit (baseline).
- Subject had a positive test result for hepatitis B surface (HBs) antigen, hepatitis C virus (HCV) antibody or human immunodeficiency virus (HIV) antigen/antibody.

- Subject has immune disorders (including autoimmune disease) and/or diseases requiring immunosuppressive drugs.
- Subject was diagnosed with immunodeficiency in the past.
- Subject has uncontrolled hypertension.
- Subject has a history of cardiovascular disease, arrhythmias, chronic lung disease, active eosinophilic gastrointestinal disease or any other medical or surgical conditions, which, places the subject at increased risk for participation in the study.

- Subject has mental conditions such as schizophrenia, bipolar disorder, dementia or major depressive disorder.

- Subject has received investigational therapy within 35 days or 5 half-lives, whichever is longer, prior to screening.
- Subject's parent(s) or legal guardian is an employee of the Astellas Group or vendors involved in the study.
- Subject has any condition, which, makes the subject unsuitable for study participation.

Intervention / Treatment |
---|---|
Experimental: ASP0892 Low Dose (Cohort A)
Each cohort will consist of 10 participants (ASP0892 n = 8 and placebo n = 2).
The data will be assessed by the Data Monitoring Committee (DMC) after all enrolled cohort A participants complete visits through day 43.
Assessments for safety, tolerability, and dose escalation will occur prior to beginning cohort B.
|
Intradermal
|
Experimental: ASP0892 High Dose (Cohort B)
After all participants in cohort A complete study procedures, the DMC will review the safety and tolerability data and provide recommendations depending on the nature, frequency and severity of the safety profile reviewed.
Recommendations will be to proceed with escalation to the next higher dose or stop dose escalation (i.e., no further dosing with study drug).

Placebo Comparator: Placebo
Each cohort will consist of 10 participants (ASP0892 n = 8 and placebo n = 2).
The data will be assessed by the Data Monitoring Committee (DMC) after all enrolled cohort A participants complete visits through day 43.
