Bio-Thera Solutions and Intract Pharma Enter Global Collaboration and License Agreement for Soteria® and Phloral® Drug Delivery Technologies to Enable Development of Oral Antibody Medicines

London, UK. September 27th 2021.

GUANGZHOU, China, September XX, 2021 (BUSINESSWIRE) – Bio-Thera Solutions, Ltd. (688177.SH, “Bio-Thera”) and Intract Pharma (“Intract”) announced a global collaboration and licensing agreement that gives Bio-Thera access to Intract’s Soteria® and Phloral® drug delivery technologies to develop novel oral monoclonal antibody (mAb) treatments for chronic gastrointestinal (GI) inflammatory diseases.  Bio-Thera is a global pharmaceutical company developing innovative therapeutics and biosimilars for oncology, autoimmune diseases, cardiovascular diseases, and other serious unmet medical needs.

Under the terms of the agreement, Intract has granted Bio-Thera a worldwide license to Intract’s oral biologics drug delivery platform for a single undisclosed mAb product. Intract will receive an undisclosed upfront payment, with potential development and commercial milestone payments along with royalties on product sales. Intract will lead preclinical research of the product and Bio-Thera will have the option to expand development of the product for multiple GI indications and will be responsible for manufacturing and commercialization of any approved products. 

Intract’s oral biologics delivery platform includes Soteria® a technology which protects proteins such as mAbs from degradation in the intestinal lumen. The platform also includes Phloral®, a clinically-validated  technology that utilizes both pH and the enzymes produced by colonic bacteria as a trigger mechanism to allow accurate release of payloads in the colon, a suitable site in the GI tract for targeting of biologics for local and systemic delivery.   

“Developing oral biologics is the next step in advancing compliance and access to innovative monoclonal antibodies for chronic diseases,” said Dr. Shengfeng Li, CEO of Bio-Thera Solutions. “We believe that combining Bio-Thera’s antibody expertise with Intract’s oral delivery platform will lead to a great advance in the treatment of gastrointestinal disease.”

“Intract Pharma is delighted to be partnering with Bio-Thera to address the significant challenge of delivering powerful biologics orally” said Dr Bill Lindsay, CEO of Intract. “We believe that our technologies will allow development of a more effective therapeutic for the treatment of IBD, while also increasing drug safety and reducing cost.”
