Long-term Extension Study of Ligelizumab in Food Allergy

Phase 3
Terminated
Conditions
Food Allergy
Interventions
Registration Number
NCT05678959
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

This is an extension study to evaluate the long-term safety and efficacy of ligelizumab in participants who have completed a ligelizumab Phase III study in food allergy.

Detailed Description

Participants will receive up to 3 years treatment with ligelizumab after which they will enter a follow-up period for 16 weeks. During the study, participants will undergo allergy testing by a Skin Prick Test and Oral Food challenge to test if the treatment is working or not. Accordingly, this study will generate data that should provide guidance relative to the long-term (chronic) use of ligelizumab in food allergic patients in terms of safety, efficacy, pharmaco-dynamics, biomarkers and Qualify of Life, and potential discontinuation from treatment.

During the study, treatment will be administered every 4 weeks and while this can take place in the hospital clinic, some participants will be trained to administer study treatment at home by either the participant or parent/caregiver. Participants at home will record administration of the study treatment on a dosing log and return this to the clinic for review.

Inclusion Criteria
  • Signed informed consent form (ICF) and assent form (where applicable) obtained from the participant/legal representative before study participation. If a minor participant reaches the age of legal majority (as defined by local law), they must be re-consented at the next study visit
  • Participants have completed the treatment period in any ligelizumab Phase III studies in food allergy
  • Participants who are willing to adhere to the study visits and procedures, including receiving injections (study treatment) and participating in the OL-OFC (open label oral food challenge)
  • Participants who agree to continue avoiding exposure to allergens (per core study) and any other foods they are allergic to throughout this study
  • Participants who are able to safely continue into the study as judged by the investigator

Key

Exclusion Criteria
  • Development of a severe or life-threatening episode of an allergic reaction that required intubation and/or ICU admission during the core studies
  • Development of a serious adverse event which is suspected to be related to the study treatment judged by the investigator during the core study
  • Development of uncontrolled asthma during the core study that could compromise the safety of the participants judged by the investigator
  • Development of clinically significant cardiovascular, neurological, and or psychiatric conditions during the core study that could interfere with or compromise the safety of the participants, interfere with evaluation or interpretation of the study results or preclude completion of the study judged by the investigator
  • Participants who failed to comply with the protocol requirements and procedures during the core study, and in the Investigator's opinion they should not participate in this extension study
  • Platelets <75,000/ul at end of treatment of the core study

Other protocol defined inclusion/exclusion criteria may apply

Primary Outcome Measures
NameTimeMethod
Number of treatment-emergent AEs and SAEsUp to 172 weeks

Long-term safety and tolerability of ligelizumab measured by incidence of Adverse Events and Serious Adverse Events

An Adverse Event (AE) is any untoward medical occurrence, unfavorable, or unintended sign (including an abnormal laboratory finding), symptom, disease, or injury, temporally associated with the use of a marketed or investigational medicinal product, gene therapy, theragnostic product, or medical device, in patients, clinical-trial subjects, device users, or other persons, whether or not it is considered to be related to or due to the product.

Secondary Outcome Measures
NameTimeMethod
Number of participants tolerating a single dose of more than or equal to 600 mg of peanut protein without dose-limiting symptomsDay 1, Week 52, Week 104, Week 156

Long-term efficacy of ligelizumab

Scores in the Food Allergy Independent Measure (FAIM) by age and responderDay 1, 10 days before and 3 days after Week 52, 10 days before and 3 days after Week 104, 10 days before and 3 days after Week 156

Long-term impact of ligelizumab on the health-related qualify of life of patients with food allergy. Scores range from 1 (limited) to 7 (greatest) perceived food allergy severity and food allergy related risk.

Number of treatment emergent AEs and SAEsUp to 172 weeks

Safety and tolerability of ligelizumab in all participants who administered study treatment at home by self-administration or parent/caregiver

Scores in the Food Allergy Quality of Life Questionnaire (FAQLQ) by age and responderDay 1, 10 days before and 3 days after Week 52, 10 days before and 3 days after Week 104, 10 days before and 3 days after Week 156

Long-term impact of ligelizumab on the health-related qualify of life of patients with food allergy. Questions are scored on a 7 point scale from 1 (no) to 7 (maximal) impairment on quality of life.

Scores in the Medical Outcomes Study 36-item Short Form Version 2 Acute Version (SF36v2) by age and responderDay 1, 10 days before and 3 days after Week 52, 10 days before and 3 days after Week 104, 10 days before and 3 days after Week 156

Long-term impact of ligelizumab on the health-related qualify of life of patients with food allergy. This 36 item instrument measures the impact of food allergy on social activities and depressions/nervousness.
