MELBOURNE, Jan 16, 2024 – (ACN Newswire via – Prota Therapeutics Pty Ltd (Prota), an Australian biotechnology company focused on the development of novel oral immunotherapy treatments that induce remission of allergy, today announced financing of US$21 million in equity and debt financing. The round, led by Singapore-based SPRIM Global Investments (SGI), will help the company prepare for a Phase 3 clinical investigation of the company’s PRT120 oral therapy for peanut allergy.

“SPRIM brings valuable expertise, capabilities and an international investment network to Prota’s technology and clinical program,” said Prota Executive Chairman Kelly Constable. “This partnership and funding will accelerate Prota’s drug development plans and clinical trial program, and we look forward to this strategic collaboration as Prota moves toward its Phase 3 trial.”

“Closing financing in the current market validates the potential of Professor Mimi Tang’s technology to deliver meaningful outcomes for patients with peanut allergy, where there is a persistent unmet need,” said Dr. Paul Kelly, founding partner and director, OneVentures, one of Australia’s leading Venture Capital firms with more than AU$800 million under management. “Prota’s treatment offers the promise of an induction of remission of allergy, allowing patients to eat peanuts freely and enjoy an improved quality of life.”

The new investment will advance the chemistry, manufacturing, and controls (CMC), accelerate the path to an Investigational New Drug Application (IND), and expand Prota’s executive management team to bring on board critical expertise in late-stage drug development and commercialization.

The peanut allergy therapeutics market is projected to reach US$1 billion by 2030, growing at a compound annual rate of 10%, in part due to the increasing incidence of peanut allergy globally. In the US, peanut allergy is the most prevalent food allergy in children, affecting 2.5% of children. The most significant impact of food allergy on both patients and their families is a reduced quality-of-life and psychological distress, caused by the lifestyle and dietary restrictions of allergen avoidance and the unpredictability of reactions to accidental exposures.

Prota’s technology is based on over 15 years of research led by Professor Mimi Tang at the Murdoch Children’s Research Institute (MCRI).

“Our Phase 2b[1] multicenter randomized controlled trial conducted by MCRI showed that PRT120 is highly effective at inducing remission of allergy, and more importantly, leads to significant and clinically meaningful improvement in quality of life, compared with standard care (placebo treatment),” said Prota founder Professor Tang. “Long-term follow-up data further shows that children in remission have fewer reactions, less rescue epinephrine use, and far greater improvement in quality of life than children who are only desensitized, validating remission as the patient-preferred outcome.”

“The food immunotherapy market is expanding rapidly with a range of therapies currently in early- through late-stage development. We are excited to support Prota in its journey to deliver a solution that can potentially transform the treatment of peanut allergy by releasing patients from the shackles of life-long maintenance dosing and allergen avoidance,” said Michael Shleifer, managing partner and co-founder of SGI, a leading health sciences venture capital firm with deep industry expertise and decades of operating experience across 17 countries.
