Last Update: Aug 28, 2026 A 52-week Multicenter, Randomized, Double-blind, Placebo-controlled Study to Assess Efficacy and Safety of Remibrutinib (LOU064) in Adult and Adolescent Participants With IgE-mediated Food Allergy ClinicalTrials.gov Identifier: [NCT07768371](https://clinicaltrials.gov/ct2/show/NCT07768371) Novartis Reference Number:CLOU064I12301 [See if you Pre-qualify](#trial-eligibility "See if you Pre-qualify") All compounds are either investigational or being studied for (a) new use(s). Efficacy and safety have not been established. There is no guarantee that they will become commercially available for the use(s) under investigation. ## Study Description The purpose of this Phase III study is to evaluate the clinical efficacy and safety of remibrutinib in participants with peanut, or cow's milk ("milk", cooked and uncooked) or hen's egg ("egg", cooked and uncooked) immunoglobulin E (IgE)- mediated allergy in comparison to placebo. This study is a Phase III, 52-week, multi-center, placebo controlled pivotal study to evaluate the efficacy and safety of remibrutinib compared to placebo in adolescent and adult participants with peanut, milk, or egg IgE-mediated allergy. This study will be conducted in 4 Sub-studies: Sub-study 1 to evaluate response to peanut allergen at Week 24, Sub-study 2 to evaluate response to milk allergen at Week 24, Sub-study 3 to evaluate response to egg allergen at Week 24, and Sub-study 4 to evaluate response to peanut or milk, or egg allergen at Week 4. Treatment period 1: Participants will receive one of the two treatment groups, double-blind remibrutinib or placebo, for a period up to 24 weeks for Sub-studies 1, 2, and 3, and up to 4 weeks for Sub-study 4. Treatment period 2: For all Sub-studies, the open label period starts at Week 24, except for Sub-study 4, where the open label period starts at Week 4. Participants from each Sub-study will continue in the study and receive, or initiate, active open label remibrutinib until Week 52. Following completion of the treatment period 2, eligible participants may enroll in a separate open-label post-trial access study and receive remibrutinib to evaluate long-term treatment effects. Participants who do not enroll in the post-trial access study will enter a 4-week safety follow-up period off treatment, during which adverse events will be monitored. Condition IgE-Mediated Food Allergy, Peanut Allergy, Cow Milk Allergy, Egg Allergy Phase Phase3 Overall Status Recruiting Number of Participants576 Start Date Sep 11, 2026 Completion Date Dec 31, 2029 Gender All Age(s) 12 Years - 65 Years (Child, Adult, Older Adult) ## Interventions Drug ### Placebo Oral administration of placebo. Drug ### Remibrutinib Oral administration of remibrutinib. ## Eligibility Criteria Inclusion Criteria: \* Signed informed consent and/or assent (where applicable) must be obtained prior to study participation. Participant (and parent/legal guardian for adolescents) must be able to understand and provide informed consent and assent, as applicable. If a minor participant providing assent reaches the age of legal majority (as defined by local law), he/she must be re-consented (ICF) at the next study visit. \* Male or female participants who are 12 to 65 years of age, inclusive, at the time of signing informed consent/assent. \* Positive allergen-specific (peanut, milk, or egg), IgE (≥ 0.35 kUA/L) at Screening Visit 1. \* Positive Skin Prick Testing (SPT) for peanut, milk, or egg at Screening Visit 1. This is defined as the average diameter (longest diameter and mid-point orthogonal diameter) ≥ 4 mm wheal compared to the negative control. \* A positive DBPCFC at baseline (Screening Visit 2), defined as the occurrence of dose-limiting symptoms at a single dose: \* ≤ 100 mg of peanut allergen protein \* ≤ 300 mg for milk or egg allergen protein \* Participants must be able and willing to participate in the DBPCFC and must be willing to continue avoiding exposure to peanut, milk (cooked and uncooked), or egg (cooked and uncooked) and any other foods that they are allergic to throughout this study. Exclusion Criteria: \* Previous use of remibrutinib or other Bruton Tyrosine Kinase (BTK) inhibitors. \* History of hypersensitivity to study drug or its excipients or to drugs of similar chemical classes. \* Hypersensitivity or intolerance to any of the matrix components used within the material for the DBPCFC. \* Any occurrence of dose-limiting symptoms against placebo allergen at baseline DBPCFC (Screening Visit Part 1 and/or Part 2). \* Medical examination, medical conditions or laboratory findings that, in the opinion of the investigator, renders the participant unsuitable for the study. Other protocol-defined inclusion/exclusion criteria may apply.
