简要总结
The aim of this study is to confirm safety and tolerability of incremental doses of HAL-MPE1 subcutaneous immunotherapy (SCIT) in peanut allergic adults, and subsequently assess the safety and tolerability in adolescents and children with peanut allergy.
详细描述
At the time of the study there was no effective treatment available for peanut allergy other than avoidance of peanut allergens. There was high unmet medical need for a disease modifying treatment for peanut allergy, especially for peanut allergic children, since this age group is at highest risk of peanut-related anaphylaxis requiring hospitalization. A chemically modified, aluminum hydroxide adsorbed peanut extract (HAL-MPE1) for subcutaneous administration has been developed. The safety and tolerability of HAL-MPE1 have been established in a First-in-human (FIH) study in adults.

入选标准
- •Signed informed consent/assent
- •Male or female subjects aged 5- 50 years
- •A well-documented medical history of systemic reactions after ingestion of peanut
- •Positive serum specific anti-peanut (>5.0 kU/L) and Ara h 2 Immunoglobulin E (IgE)-test (>2.0 kU/L)
- •Skin prick test (SPT) to peanut ≥3 mm compared to negative control within the last 2 years
- •Forced expiratory volume at first second (FEV1)>80% predicted (adults and adolescents) or Peak expiratory flow(PEF)>80% predicted (children)
- •Negative pregnancy test at screening for females of childbearing potential
- •Females of childbearing age must be using an effective method of contraception to prevent pregnancy and agree to continue to practice an acceptable method of contraception for the duration of participation in the study. Contraceptive measures considered adequate are:

- •surgical sterilization of the female participant (removal of the uterus or ovaries or tubal ligation)
- •participants who are postmenopausal (12 consecutive months without a period) for at least 2 years
- •male partner sterilization (vasectomy with documentation of azoospermia) prior to the female patient's entry into trial and is the sole sexual partner for that female patient
- •sexual abstinence or having no sexual relationship with a man.
排除标准

- •Clinical features of moderate or severe persistent asthma (as guided by the 2007 NHLBI Guidelines and according to the opinion of the investigator)
- •Asthma with FEV1<80% predicted (adults, adolescents) or PEF <80% predicted (children)
- •Asthma Control Test (ACT) ≤ 19
- •Asthma attack/exacerbation within the last 3 months
- •Hospitalization due to asthma within the last year
- •Two or more courses of oral steroids within the last 6 months
- •History of intubation /mechanical ventilation due to allergies or asthma
- •Participation in any interventional study with peanut immunotherapy in the last year
- •Any specific immunotherapy (SCIT, Sublingual Immunotherapy (SLIT) or OIT) during the study period
- •Severe immune disorders (including autoimmune diseases) and/or diseases requiring immunosuppressive drugs
- •Presence of chronic urticaria, atopic dermatitis with flare or atopic dermatitis with SCORAD>40
- •Active malignancies or any malignant disease within the past 5 years
- •Severe (uncontrolled) diseases that could increase the risk for subjects participating in the study, including but not limited to: any severe or unstable lung diseases; endocrine diseases; clinically significant renal or hepatic diseases, renal impairment, haematological disorders; severe ongoing symptomatic allergic diseases
- •History of cardiovascular disease, uncontrolled hypertension or arrhythmias
- •Diseases with a contraindication for the use of epinephrine (e.g. hyperthyroidism, glaucoma)
- •Use of systemic steroids within 4 weeks before start of the study and during the study
- •Treatment with beta-blockers or angiotensin-converting enzyme (ACE) inhibitors
- •Vaccination within one week before start of therapy or during study unless considered necessary based on the opinion of the investigator.
- •Anti-IgE/anti-Tumor Necrosis Factor (TNF)/omalizumab therapy or any biologic immunomodulatory therapy within the 6 months prior to inclusion and during the study
- •Participation in a clinical study with a new investigational drug within the last 3 months or for a biological within the last 6 months prior to or during the study
- •For female adolescents and adults of childbearing potential: Pregnancy (test performed at screening), lactation or inadequate contraceptive measures for women of child-bearing age (contraceptive measures considered adequate are: intrauterine devices, hormonal contraceptives, such as contraceptive pills, implants, transdermal patches, hormonal vaginal devices or injections with prolonged release, sexual abstinence or having no sexual relationship with a man)
- •Alcohol, drug or medication abuse within the past year
- •Any clinically significant abnormal laboratory parameter at screening
- •Lack or expected lack of cooperation or compliance
- •Unable to use the epinephrine pen correctly
- •Severe psychiatric, psychological, or neurological disorders
- •Subjects who are employees of the sponsor, institution or 1st degree relatives or partners of the investigators
