BridgeMD
A multicenter double-blind, randomized, placebo-controlled phase I/II study to determine the safety, tolerability, potential efficacy and dose finding of INP20, an oral formulation for treatment of immunotherapy in peanut-allergic patients.
EU CTIS ID: 2024-518501-17-00
What this study is testing
Part A: Dose-ranging study (dose escalation): To determine the MTD and the recommended oral dose of INP20 in repeated-dose oral administration to patients with peanut allergy. The safety and tolerability of rising oral doses of INP20 will be assessed to identify a safe dose range for Phase II assay. Part B: Parallel Group Extension study: To evaluate the safety and tolerability of INP20 in repeated-dose oral administration at the recommended dose(s) in patients with peanut allergy throughout the treatment period of 6 months.

- Age 12 years and above of either sex, any race, any ethnicity at the time of the initial visit.
- The presence of specific IgE to peanuts (a positive skin prick test to peanuts (diameter of wheal > 3.0 mm) and a positive peanut IgEs [CAP-FEIA] > 0.35 kUA/L.
- A history of significant clinical symptoms (urticaria, angioedema, rhinorrhea, nasal congestion, pruritus, sneezing, abdominal pain, emesis, diarrhea, wheezing, shortness of breath, lip/tongue swelling, throat itching, throat swelling or impending sense of doom) occurring within 60 minutes after ingesting peanuts or history of unknown tolerance to peanut due to consumption avoidance.
- Have a positive DBPCFC to peanut at a cumulative dose of less than 8.5565 grams of peanut protein.
- Provide signed informed consent for the participation in the study. In males and females aged 12-17 years old the informed consent will be signed and dated by them, and also by the parent(s) or the subject's legally acceptable representative(s).
- Have self-injectable epinephrine available at home and be trained on its proper use.
You likely can't join if
- History of severe anaphylaxis to peanut as defined by respiratory distress with cyanosis, hypoxemia (O2 Sat <92%) or, in the absence of other clinical records, severe dyspnea; hypotension with or without loss of consciousness; or relaxation of sphincters.
- Chronic use of beta blockers, angiotensin converting enzyme inhibitors, or monoamine oxidase inhibitors, proton pump inhibitors, H2-bloquers, prokinetic drugs and laxatives.
- Women of childbearing potential (defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for at least 1 month after stopping medication) who are pregnant, planning to become pregnant, or breastfeeding.
- Currently participating in another study using an investigational new drug.
- Participation in any interventional study, specific oral or sublingual immunotherapy building up phase for the treatment of food allergy in the past 12 months. Patients in treatment with specific oral maintenance phase of OIT will be considered individually, to investigator’s discretion.
- Use within the past year of any systemic immunomodulatory treatment (i.e. cyclosporine, omalizumab, etc.), including inhalants immunotherapy building up phase. It is allowed the use of immunotherapy in the maintenance dosing against pollens, mites, animal dander and/or alternaria
