Biora Therapeutics Shares Preclinical Data on Oral Delivery of Biologics at the 2022 Parenteral Drug Association Universe of Pre-Filled Syringes and Injection Devices Conference
Further Demonstrating Possibilities for Systemic Delivery of Large Molecules
SAN DIEGO, Oct. 19, 2022 (GLOBE NEWSWIRE) -- Biora Therapeutics, Inc. (Nasdaq: BIOR), the biotech company that is reimagining therapeutics, today shared a poster presented at the Parenteral Drug Association (PDA) Universe of Pre-Filled Syringes and Injection Devices Conference. The meeting in Palm Springs, California, October 18-19, 2022 explored the latest technological advances with drug delivery devices.
“Our platform is the first designed to use submucosal liquid jet injection to the small intestine for oral delivery of large molecules,” said Sharat Singh, PhD, Head of Research at Biora Therapeutics. “One challenge with a completely novel delivery method is there are no existing models to follow for preclinical development. We are encouraged by the data from the early results for these preclinical models, which informs the ongoing development of our systemic therapeutics platform,” continued Dr. Singh.
The company presented a poster titled “Development of a submucosal injection device for an oral biotherapeutic delivery system,” presenting previous preclinical studies in which researchers determined animal models to use for evaluation of device performance and pharmacokinetics. They then evaluated device performance in a canine model using oral administration of the OBDS device and assessed pharmacokinetics in a swine model using endoscopic administration of the device.
The company successfully demonstrated ≥83% deployment accuracy in the canine small intestine, showing consistent deployment time post gastric emptying without early deployment in the stomach. Functionality of the endoscopic delivery method in swine was also demonstrated, with all devices successfully released in the small intestine to transit naturally and autonomously deploy in the small intestine. Eight animals showed detectable drug levels of a variant of adalimumab with an oral bioavailability average of 25% (range from 7-55%), excluding one animal with a late deployment at 72 hours post-dose.

About Biora Therapeutics’ Systemic Therapeutics Platform
Biora Therapeutics’ systemic therapeutics platform uses an ingestible smart capsule for needle-free, oral delivery of biotherapeutics, with the potential to deliver a broad range of large molecules including monoclonal antibodies, peptides, and nucleic acids. Biora’s Oral Biotherapeutics Delivery System (OBDS) is an ingestible capsule designed to use proprietary liquid jet delivery to increase systemic uptake and bioavailability of large molecules. Once swallowed, the capsule is designed to transit through the digestive system and trigger in the small intestine, where liquid jets deliver drug directly into the intestinal tissue. The capsule is approximately the size of a multivitamin and can deliver up to 400µL of liquid formulation, such as proteins, peptides, and nucleic acids.
Biora is developing the PGN-OB2 program, which consists of a GLP-1 receptor agonist delivered via liquid jet into the small intestinal tissue using the OBDS capsule, for the treatment of type 2 diabetes. Oral GLP-1 receptor agonists are preferred by patients, and research indicates that people who start treatment with an injectable GLP-1 receptor agonist have a 71% higher discontinuation rate than those starting oral therapy. The company is currently advancing development of PGN-OB2 with preclinical studies.
