27 March 2023 Allergy Therapeutics (AIM: AGY), the fully integrated commercial biotechnology company specialising in allergy vaccines, today announces that the first application of VLP Peanut in peanut allergic patients has commenced with the Group's innovative, short-course peanut allergy vaccine candidate in the Phase I PROTECT trial. The first-in-human study is evaluating the safety and tolerability of VLP Peanut in healthy and peanut allergic adult subjects and exploring preliminary proof of efficacy.

Allergy Therapeutics' wholly-owned, subcutaneous, recombinant vaccine candidate incorporates novel virus-like particle (VLP) technology, which enhances the body's immune response by making the peanut allergen resemble an inactive virus.
