Prota Therapeutics Achieves Peanut Allergy Treatment Milestone: Groundbreaking Clinical Trial Data Demonstrates Clinical Remission of Peanut Allergy in Paediatric Patients

The research was led by Murdoch Children's Research Institute (MCRI) with Professor Mimi Tang, CEO of Prota Therapeutics, as one of the Lead Investigators. The randomised controlled trial was conducted at The Royal Children's Hospital in Melbourne, Perth Children's Hospital, and the Women's and Children's Hospital in Adelaide, involving 201 children aged between 1-10 years.

The research was led by Murdoch Children's Research Institute (MCRI) with Professor Mimi Tang, CEO of Prota Therapeutics, as one of the Lead Investigators. The randomised controlled trial was conducted at The Royal Children's Hospital in Melbourne, Perth Children's Hospital, and the Women's and Children's Hospital in Adelaide, involving 201 children aged between 1-10 years. The trial was staged over four years, with participants followed up to 12 months post-treatment.

Remission of allergy refers to the absence of clinical reactivity that persists after treatment has been stopped for a period of time. This allows patients to stop treatment and no longer adhere to strict allergen avoidance. This contrasts with desensitisation which is a temporary increase in the amount of allergen that causes a reaction for patients that is only maintained with continuing treatment. Desensitisation provides protection against accidental exposure to allergen, however patients must remain on daily treatment and also maintain strict allergen avoidance.

Previous studies of peanut oral immunotherapy have shown limited success at stimulating remission, with only a small subset of patients achieving this endpoint after years of treatment. In this new trial, 51% of children achieved remission after 18 months, compared to 5% in the placebo arm, recording the highest rate of remission yet reported for a standalone peanut oral immunotherapy treatment in school-aged children.

The study used Prota's novel dosing regimen comprising a proprietary rapid escalation, high dose approach which researchers believe contributed to the remission rates being higher than previous oral immunotherapy trials, alongside other factors including the younger age of subjects.

Professor Mimi Tang, CEO of Prota Therapeutics and Lead Researcher at MCRI says: "This is an exciting time for our company with the publication of these remarkable results. It is the first randomized controlled study of peanut oral immunotherapy to show high rates of sustained unresponsiveness in school-aged children and the first to show that a peanut allergy treatment can provide substantial improvement in quality of life compared to current standard care of peanut avoidance. We are especially gratified by the strong improvement in quality of life for these children and will continue our path to bring this treatment to patients."

Dr Paul Kelly, Founding Partner of OneVentures, one of Prota's lead shareholders, comments "We recognize that peanut allergy is a growing health concern with an increasing number of patients affected every year. We are very proud to support Prota as they strive further ahead to improve the lives of peanut-allergic patients and their families through innovative solutions. This company has the potential to transform the way peanut allergy is treated and we are excited to see it flourish."

Prota Therapeutics is looking to raise funds to support the further clinical development and commercialization of PRT120. The company's food immunotherapy technology was developed at the Murdoch Children's Research Institute (MCRI), which led the four-year research study that validated its efficacy. Founded in 2016, privately-held Prota Therapeutics has leading Australian venture capital investment firm OneVentures as largest shareholders, supporting its clinical program and commercialization.

The paediatric peanut allergy market is estimated to be worth $3 billion by 2027, with around 1.1 million patients between the ages of 1-17 diagnosed in the US alone last year[1]. This presents a significant opportunity for Prota Therapeutics to bring PRT120 to market, providing a highly differentiated long-lasting treatment that offers meaningful improvements to the quality of life of patients and their families.
