Brief Summary:
This is a 52-week, Phase 3 multi-center, randomized, double-blind and placebo-controlled study to assess the safety and clinical efficacy of two dosing regimens of ligelizumab (240 mg and 120 mg) subcutaneous injection every 4 weeks (SCq4w) in participants with a medically confirmed diagnosis of IgE-mediated peanut allergy.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Allergy, Peanut | Drug: ligelizumab Drug: Placebo | Phase 3 |
This is a 52-week, Phase 3 multi-center, randomized, double-blind and placebo-controlled study to assess the safety and clinical efficacy of two dosing regimens of ligelizumab (240 mg and 120 mg) subcutaneous injection every 4 weeks (SCq4w) in participants with a medically confirmed diagnosis of IgE-mediated peanut allergy. Participants will be randomized to ligelizumab 240 mg, ligelizumab 120 mg, or placebo (5 treatment arms, randomization ratio of 2:2:2:2:1) for the double-blind placebo-controlled treatment period (up to Week 12). Participants initially assigned to the 8-week placebo arms will receive the first dose of blinded ligelizumab treatment at the Week 8 visit. Participants initially assigned to the 16-week placebo arm will receive the last dose of placebo before the double blind placebo controlled food challenge (DBPCFC) at week 12 and the first dose of blinded ligelizumab treatment at the Week 16 visit.

Primary Outcome Measures :
- Proportion of participants who can tolerate a single dose of ≥ 600 mg (1044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms at Week 12 [ Time Frame: Week 12 ]Responder status is defined as tolerating a single dose of ≥ 600 mg (1044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms during the double blind placebo controlled food challenge (DBPCFC) conducted at Week 12
Secondary Outcome Measures :
- Proportion of participants who can tolerate a single dose of ≥ 1000 mg (2044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms at Week 12 [ Time Frame: Week 12 ]Responder status is defined as tolerating a single dose of ≥ 1000 mg (2044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms during the DBPCFC conducted at Week 12
- Proportion of participants who can tolerate a single dose of 3000 mg (5044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms at Week 12 [ Time Frame: Week 12 ]Responder status is defined as tolerating a single dose of 3000 mg (5044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms during the DBPCFC conducted at Week 12
- Maximum severity of symptoms occurring at any challenge dose of peanut protein up to and including 1000 mg at Week 12 [ Time Frame: Week 12 ]Maximum severity of symptoms will be assessed during the DBPCFC conducted at Week 12. Symptom severity will be categorized as 4 levels: None, Mild, Moderate, Severe
- Proportion of participants who can tolerate a single dose of ≥ 1000 mg (2044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms at Week 52 [ Time Frame: Week 52 ]Responder status is defined as tolerating a single dose of ≥ 1000 mg (2044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms during DBPCFC conducted at Week 52
- Change in maximum tolerated dose (MTD) of peanut protein without dose-limiting symptoms during the DBPCFC at Week 52 compared to Week 12 [ Time Frame: Week 12 and Week 52 ]Change in MTD of peanut protein without dose-limiting symptoms at Week 52 compared to Week 12. Dose-limiting symptoms indicate a true allergic reaction occurring during administration of a single dose of peanut protein at the DBPCFC that should preclude the administration of any further doses in the view of the investigator.
- Change from baseline in peanut-specific IgE at Week 12, Week 16 and Week 52 [ Time Frame: Baseline, Week 12, 16 and 52 ]Change from baseline of serum levels of peanut-specific immunoglobulin E (IgE)
- Change from baseline in peanut-specific IgG4 at Week 12, Week 16 and 52 [ Time Frame: Baseline, Week 12, 16 and 52 ]Change from baseline of serum levels of peanut-specific immunoglobulin G4 (IgG4)
- Change from baseline in SPT mean wheal diameters at Week 16, Week 56 and Week 68 [ Time Frame: Baseline, Week 16, 56 and 68 ]Change from baseline (screening) in skin prick test (SPT) mean wheal diameters.
- Change from baseline in total and domain scores in the FAQLQ by age and responder (subject and/or caregiver) [ Time Frame: Baseline, Week 12 and 56 ]The impact of ligelizumab on the health-related quality of life (HRQoL) of participants with a food allergy will be assessed by Food Allergy Quality of Life Questionnaire (FAQLQ)
- Change from baseline in total and domain scores in the FAIM by age and responder (subject and/or caregiver) [ Time Frame: Baseline, Week 12 and 56 ]The impact of ligelizumab on the health-related quality of life (HRQoL) of participants with a food allergy will be assessed by Food Allergy Independent Measure (FAIM).
- Change from baseline in total and domain scores in the SF-36v2 by age and responder (subject and/or caregiver) [ Time Frame: Baseline, Week 12 and 56 ]The impact of ligelizumab on the health-related quality of life (HRQoL) of participants with a food allergy will be assessed by a Medical Outcomes Study 36-Item Short Form Version 2 (SF-36v2).
