About this study

Official title: A Three-year, Multi-center, Double-blind, Extension Study to Evaluate the Long-term Safety and Efficacy of Ligelizumab in Patients Who Completed Ligelizumab's Phase III Studies in Food Allergy

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

Read the detailed description

This was a 3-year extension study with a 16-week follow-up period. The study enabled participants from planned multiple Phase III "core" studies to roll over to this extension study once the participants had completed predefined minimal requirements of a "core" study and agreed to consent to participate in this study.

Participants received ligelizumab treatment allocated in the core study, except for maximum responder (MR) participants performing conditional discontinuation of study treatment. Any participant considered a MR, as defined by an oral food challenge (OFC), performed conditional discontinuation of study treatment. This was to assess whether further treatment was still required because of disease modification by ligelizumab and/or a change in the underlying phenotype following the natural history of the disease (outgrowth of allergy) demonstrated by sustained unresponsiveness.

A subset of participants was offered administration of study treatment at home either by the participant him/herself (self-administration) or by parent/caregiver following training at three visits at the clinic.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)

    TEAEs were defined as events where an AE either started after the first dose of extension study treatment and within 16 weeks after the last administered study treatment dose or began prior to the first dose of study treatment but increased in severity (based on preferred term) within 16 weeks after the last study treatment.

    Measured: Up to approximately 81 weeks

Secondary outcomes (7)
  1. Number of Participants Tolerating a Single Dose of More Than or Equal to 600 mg of Peanut Protein Without Dose-Limiting Symptoms

    Assessed during an open-label oral food challenge (OFC). If missing Week 52-OFC assessments, Week 156-OFC assessments were performed within 380 days (inclusive) after first extension dose date and considered as Week 52-OFC assessments.

    Measured: Up to approximately 97 weeks

  2. Percentage of Participants With TEAEs and TESAEs, Assessed in Participants With at Least One Home Administration of Study Drug

    TEAEs were defined as events where an AE either started after the first dose of extension study treatment and within 16 weeks after the last administered study treatment dose or began prior to the first dose of study treatment but increased in severity (based on preferred term) within 16 weeks after the last study treatment.

    Measured: Up to approximately 81 weeks

  3. Change From Baseline in Total Scores in the Food Allergy Quality of Life Questionnaire (FAQLQ) Teenager Form (FAQLQ-TF)

    The FAQLQ-TF is a self-reported instrument designed for adolescents aged 13-17 to assess the impact of food allergy on health-related quality of life (HRQoL). The questionnaire includes three domains (emotional impact, allergen avoidance and dietary restrictions, and risk of accidental exposure). Each item was scored on a 7-point scale, with a higher score indicating greater impairment in HRQoL. The total score was calculated as the arithmetic average of all completed items. The possible range for the total score was 1 (minimum) to 7 (maximum). The higher the score, the greater the impairment in HRQoL. OFC = oral food challenge.

    Measured: Up to approximately 97 weeks

  4. Change From Baseline in Total Scores in the Food Allergy Quality of Life Questionnaire (FAQLQ) Adult Form (FAQLQ-AF)

    The FAQLQ-AF is a self-reported instrument designed for adults aged 18-55 to assess the impact of food allergy on health-related quality of life (HRQoL). The questionnaire includes four domains (emotional impact, allergen avoidance and dietary restrictions, risk of accidental exposure, and food allergy-related health). Each item was scored on a 7-point scale, with a higher score indicating greater impairment in HRQoL. The total score was calculated as the arithmetic average of all completed items. The possible range for the total score was 1 (minimum) to 7 (maximum). The higher the score, the greater the impairment in HRQoL. OFC = oral food challenge.

    Measured: Up to approximately 97 weeks

  5. Change From Baseline in Total Scores in the Food Allergy Independent Measure (FAIM) Teenager Form (FAIM-TF)

    The FAIM-TF is a self-reported instrument designed for adolescents aged 13-17. It aims to reflect the participant's perceived food allergy severity and food allergy-related risk. The questionnaire consists of six questions. The first four questions assess the participant's food allergy expectation outcomes, and the remaining two questions reflect aspects of the perceived severity of food allergy. The total score was calculated as the arithmetic average of all completed items. The possible range for the total score was 1 (minimum) to 7 (maximum). The higher the score, the greater the perceived risk or chance of adverse events occurring. OFC = oral food challenge.

    Measured: Up to approximately 97 weeks

  6. Change From Baseline in Total Scores in the Food Allergy Independent Measure (FAIM) Adult Form (FAIM-AF)

    The FAIM-AF is a self-reported instrument designed for adults aged 18-55. It aims to reflect the participant's perceived food allergy severity and food allergy-related risk. The questionnaire consists of six questions; The first four questions assess the participant's food allergy expectation outcomes, and the remaining two questions reflect aspects of the perceived severity of food allergy. The total score was calculated as the arithmetic average of all completed items. the range for each item and the total score is from 1 (minimum) to 7 (maximum). The possible range for the total score was 1 (minimum) to 7 (maximum). The higher the score, the greater the perceived risk or chance of adverse events occurring. OFC = oral food challenge.

    Measured: Up to approximately 97 weeks

  7. Change From Baseline in the Medical Outcomes Study 36-item Short Form Version 2 Acute Version (SF-36v2) Physical Component Score (PCS) and Mental Component Score (MCS)

    The SF-36v2 Health Survey is a 36-item instrument that measures generic health-related quality of life. It contains 8 scales and 2 component summary indices evaluating physical, social, and emotional functioning in addition to general health perceptions and mental health. PCS and MCS scores range from 0 to 100, with higher scores indicating better health outcomes.

    Measured: Up to approximately 97 weeks
