Condition(s) targeted: Peanut Allergy

Intervention: HAL-MPE1 (Drug); Placebo (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: HAL Allergy

Carsten Bindslev-Jensen, Prof. Dr., Principal Investigator, Affiliation: Hudafdeling I og Allergicentret, Odense Universitetshospital

Summary

Currently, there is no effective causal treatment for peanut allergy. A chemically modified, aluminium hydroxide adsorbed peanut extract (HAL-MPE1) for subcutaneous administration has been developed. Results from in vitro and in vivo preclinical studies demonstrate the immunotherapeutic potential of HAL-MPE1. Therefore, a phase I, single-centre clinical trial has been designed to assess the safety and tolerability of HAL-MPE1 in peanut allergic patients.

Clinical Details

Official title: A First-in-human, Randomized, Double Blind, Placebo Controlled, Single-centre Study to Assess the Safety and Tolerability of HAL-MPE1 in Patients With Peanut Allergy

Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Safety of a SCIT-treatment with HAL-MPE1 in patients with peanut allergy.

Secondary outcome:

Change in serum levels of allergen specific immunoglobulins

Change in basophil histamine release test

Change in titrated skin prick test
