A Study to Evaluate Safety, Tolerability and Immune Response in Adolescents Allergic to Peanut After Receiving Intradermal Administration of ASP0892 (ARA-LAMP-vax), a Single Multivalent Peanut (Ara h1, h2, h3) Lysosomal Associated Membrane Protein DNA Plasmid Vaccine
The purpose of this study is to evaluate the safety and tolerability of ASP0892 after intradermal (ID) injection in adolescent participants with peanut allergy.
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

- - 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.
- - 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.
- - 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) within 28 days prior to the administration of the study vaccine or at any time during the study.
- - 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'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 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 and major depressive disorder.
- - Subject has severe or poorly controlled atopic dermatitis or generalized eczema.
- - Subject is unable to discontinue antihistamines within 7 days or 5 half-lives (whichever duration is longer) prior to SPT and oral food challenge procedures.

- - Subject has already received injection of Lysosomal associated membrane protein (LAMP)-vax such as ASP0892.
- - 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.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
