CNP-201 in Subjects With Peanut Allergy

Stopped early · Phase 1 · Has a placebo group

Conditions studied: Peanut Allergy

In brief

This study is a Phase 1b/2a clinical trial to assess the safety, tolerability, and pharmacodynamics of multiple ascending doses (Escalation Phase) of CNP-201 with the goal of identifying a safe and tolerable dose level to be evaluated further in a larger number of subjects (Expansion Phase).

Who can join

Age: 16 and older, up to 55. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Men and non-pregnant women, ages 16 to 55 years inclusive.
• Subjects with physician-diagnosed peanut allergy or documented history of peanut allergy. Note: If subject does not have documented history in their medical record but is reasonably suspected of having peanut allergy and is deemed to otherwise be a good candidate for this trial, the screen testing (peanut specific IgE, SPT, etc.) may be used to establish the peanut allergy and the PI may subsequently document the peanut allergy to fulfill this inclusion criterion.
• Subjects with weight ≥ 31.25 kg at Screening. Subjects who fall outside of this range may be included at the discretion of the investigator.
• Subjects with a documented history of non-severe anaphylaxis (Grade ≤ 3) to peanuts, including mild wheezing or dyspnea without hypoxia.
• Subjects with peanut specific IgE > 5 kU/L as measured by ImmunoCAP at Screening. Subjects who have previously been on OIT for peanut allergy and who do not have peanut specific IgE ≥ 5 kU/L as measured by ImmunoCAP at Screening may be included at the discretion of the investigator, OR Subjects with a positive skin prick test (SPT) to peanut with a change in wheal diameter ≥ 3 mm as compared to a negative control (50% glycerin) at Screening. Subjects who have previously been on OIT for peanut allergy and who do not have a positive skin prick test (SPT) to peanut with a change in wheal diameter ≥ 3 mm at Screening may be included at the discretion of the investigator.
• Subjects who are self-reported to be on a peanut free diet with no suspected peanut exposure, including any peanut food challenge, for at least 14 days prior to Screening and agreement to continue restriction to peanut exposure during the study.
• Female subjects and male subjects and their female spouse/partners who are willing to practice a highly effective method of contraception that may include, but is not limited to, abstinence, sex only with persons of the same sex, monogamous relationship with vasectomized partner, vasectomy, hysterectomy, bilateral tubal ligation, licensed hormonal methods, intrauterine device (IUD), or use of spermicide combined with a barrier method (e.g., condom, diaphragm) starting at Screening and continuing to Day 60.
• Female subjects who agree to not breastfeed starting at initial Screening and continuing to Day 60.
• Female subjects who agree to not donate ova starting at initial Screening and continuing to Day 60.
• Subjects who are willing and able to provide Institutional Review Board (IRB) approved written informed consent.
• Subjects who are willing to perform and comply with all study procedures.
• Male subjects who agree to not donate sperm starting at Screening and continuing to Day 60.

You may not qualify if…

• Subjects with history of severe anaphylaxis to peanuts defined as neurological compromise or requiring intubation.
• Subjects with peanut specific IgE ≥ 100 kU/L as measured by ImmunoCAP at Screening.
• Subjects who have received administration of vaccinations in the following timeframe:
• Any live vaccine (other than intranasal Influenza) within 28 days prior to Screening.
• Any subunit vaccine within 14 days prior to Screening.
• Any COVID-19 vaccine within 14 days prior to Screening. Subjects who have received the first dose of any COVID-19 vaccine may not screen for the study until 14 days following their last dose of the vaccine if applicable.
• Any planned vaccination prior to Day 15.
• Subjects in build-up phase of immunotherapy for aeroallergens or venom. Individuals tolerating maintenance aeroallergen or venom immunotherapy at Screening can be enrolled.
• Subjects with relative contraindication or inability to use epinephrine auto-injector.
• Subjects who have used the following drug(s) within 2 months prior to Screening: Th2 cytokine inhibitors, thromboxane A2 synthesis inhibitors, thromboxane A2 receptor antagonists, β-blockers, angiotensin-converting enzyme inhibitors, and/or angiotensin-receptor blockers unless, in the investigator's opinion, the underlying condition being treated by the drug is well controlled and the drug dose and frequency is not expected to interfere with the mechanism of action of CNP-201 as determined in consultation with the sponsor.
• Subjects who have used biologics and/or immune modulators (including but not limited to anti-TNFα antibody and anti-IgE monoclonal antibody) within three months prior to Screening.
• Subjects with a history of allergic reactions such as anaphylactic shock, angioedema with airway constriction, or hypotension caused by food other than peanut and/or medical products.
• Subjects with positive test results for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody, or human immunodeficiency virus (HIV) antigen/ antibody as determined at Screening.
• Subjects who are immunocompromised, including those receiving immunosuppressive doses of corticosteroids (more than 20 mg of prednisone given daily or on alternate days for 2 weeks or more within 6 months prior to Screening, any dose of corticosteroids within 30 days of Screening, or high dose inhaled corticosteroids [> 960 μg/day of beclomethasone dipropionate or equivalent]) or other immunosuppressive agents.
• Subjects with a history of unstable angina pectoris, cardiac disease or dysrhythmias, severe chronic lung disease, or any other chronic medical condition that which in the opinion of the investigator, would pose a significant health threat in the event of anaphylaxis/treatment of anaphylaxis.
• Subjects with active eosinophilic esophagitis (EoE) or other eosinophilic gastrointestinal disease.
• Subjects with clinically significant abnormality on electrocardiogram (ECG) at Screening that, in the investigator's opinion, makes the subject unsuitable for study participation.
• Subjects with active malignancy, or history of malignancy or chemotherapy within the past 5 years other than history of localized or surgical removal of focal skin cancer, or cervical cancer in situ treated successfully in the past by local treatment (including but not limited to cryotherapy or laser therapy) or by hysterectomy.
• Subjects with a mental condition such as schizophrenia, bipolar disorder, major depressive disorder, generalized anxiety disorder, panic disorder/attacks, or subjects who have received drug(s) for the treatment of dementia.
• Subjects with severe or poorly controlled (resistant to appropriate medical intervention) atopic disease including atopic dermatitis, generalized eczema, allergic rhinitis and/or urticaria.
• Subjects with tryptase values outside of the normal reference range.
• Subjects with severe or uncontrolled/difficult to control asthma/wheezing, defined by at least one of the following criteria:
• Global Initiative for Asthma (GINA) 2020: Personalized management to control symptoms and minimize future risk requiring treatment Steps 4 or 5 (Appendix 3) OR;
• Forced expiratory volume in 1 second (FEV1) < 80% of predicted, or ratio of FEV1 to forced vital capacity (FEV1/FVC) < 75% of predicted, with or without controller medications (only those able to reliable perform spirometry. If unable to do spirometry, PEF of > 80% is acceptable OR;
• One overnight admission to a hospital in the past year for asthma OR;
