ActoBio Therapeutics™ Receives IND Green Light for New Antigen-Specific Immunotherapy Study Aimed at Improving Celiac Patients' Tolerance of Gluten

GHENT, Belgium, Aug. 19, 2019 /PRNewswire/ -- ActoBio Therapeutics, Inc., a wholly owned subsidiary of Intrexon Corporation (NASDAQ: XON) and innovative clinical-stage biotechnology company focused on a new class of microbe-based therapeutic agents, announced that the U.S. Food and Drug Administration (FDA) has given its permission to an Investigational New Drug (IND) application for AG017, an innovative orally-delivered therapeutic candidate for the treatment of celiac disease. ActoBio Therapeutics^™ plans to enroll celiac disease patients in the Phase Ib/IIa study in the U.S. and Europe later this year.  

ActoBio Therapeutics^™ is dedicated to developing and commercializing the next generation of oral antigen-specific immunotherapy utilizing its proprietary delivery vehicle. ActoBiotics^® programs are very well suited to address unmet needs in a wide range of autoimmune and allergic diseases through induction of antigen-specific immune tolerance that can prevent, retard or reverse the disease. ActoBiotics^® AG017 for the treatment of celiac disease will be the second antigen-specific investigational immunotherapy candidate in clinical development following ActoBiotics^® AG019, which is currently in a Phase Ib/IIa clinical study for the treatment of type 1 diabetes. Both programs will help further advance the Company's strategy to develop antigen-specific immunotherapies toward other autoimmune indications. 

ActoBio Therapeutics^™ is developing oral ActoBiotics^® AG017 capsules based on the safe food-grade bacterium Lactococcus lactis which is specifically engineered to express a gliadin peptide in combination with an immunomodulating cytokine. ActoBiotics^® AG017 is an antigen-specific investigational immunotherapy candidate with the potential to reverse gluten sensitivity. Over 90% of patients with celiac disease have an HLA-DQ2.5 genotype, and the target population for the clinical trial is patients within this group whose celiac disease is well controlled on a gluten‑free diet.

Celiac disease is a chronic intestinal inflammatory disorder estimated to affect 1 in 100 people worldwide and is caused by an autoimmune reaction triggered by ingestion of dietary gluten proteins. The subsequent intestinal damage leads to malabsorption of some nutrients, along with diarrhea, bloating, weight loss, fatigue and anemia, as well as serious complications in some individuals¹. There is currently no FDA-approved drug for celiac disease, with the only available treatment being life-long adherence to a strict gluten free diet, which is increasingly believed to be insufficient for many sufferers.

"Celiac disease has a significant physical, emotional and practical impact on patients and their families. AG017 is a unique candidate for treating the disease, which may allow patients to relax their dietary restrictions. Therefore, we are excited to be involved in the first clinical trial with this potential treatment and look forward to exploring the promise of AG017 in addressing unmet patient needs," commented Professor Knut Lundin, one of the leading investigators for clinical studies in celiac disease and former consultant for ActoBio Therapeutics^™, professor of medicine and head of clinical education at the University of Oslo and senior consultant in gastroenterology at Oslo University Hospital.

Pieter Rottiers, PhD, chief executive officer of ActoBio Therapeutics^™ stated, "We are delighted to be moving forward and entering clinical trials with our ActoBiotics^® AG017 for celiac disease. We have demonstrated that this product is safe and efficacious in animal studies. Our approach with AG017 is to target the underlying cause of celiac disease, and this next stage of the program will allow us to evaluate how our preclinical results will translate in patients."

About Celiac Disease
Celiac disease is an autoimmune disorder, which induces an immune response to dietary gluten in genetically susceptible individuals, causing inflammation and damage to the small intestine. Around 1 in 100 people worldwide are estimated to suffer from this disorder, with many being undiagnosed and therefore at a higher risk of developing serious complications such as anemia, osteoporosis, neurological and autoimmune disorders¹.
