BioAtla And Sinobioway Select First Programs For Strategic Collaboration In China Market

SAN DIEGO, Jan. 5, 2016 /PRNewswire/ -- BioAtla LLC, a global biotechnology company focused on the development of Conditionally Active Biologic (CAB) antibody therapeutics, today announced that BioAtla and Beijing Sinobioway Group Company, Limited (Sinobioway) selected their first product programs for development.  In May 2015, BioAtla and Sinobioway entered into a strategic collaboration for the development and commercialization of select CAB antibodies and other CAB-based therapeutics in China, Hong Kong, Macau and Taiwan (the Territory). Related to and as a result of this agreement, BioAtla received a previously reported $30 million equity investment from a China-based investor group.  BioAtla now receives $19 million in program payments plus equity investment from Sinobioway as a result of the selection of the first CAB candidates and achievement of other corporate objectives. Including these funds, BioAtla will receive a total of more than $70 million in program payments and equity investment from Sinobioway over the course of the next twelve months. 

BioAtla and Sinobioway are working collaboratively to develop several CAB candidates for the Territory.  As part of the agreement, Sinobioway has exclusive rights to develop and commercialize selected CAB antibodies in the Territory and BioAtla retains the rest of world (ROW) rights to these products.  Sinobioway will fund the development, manufacturing, clinical trials and commercialization costs in the Territory and is committed to making recurring product development payments to BioAtla for additional CAB candidates.  BioAtla is further eligible to receive certain milestone payments and double-digit royalties on sales.

This strategic collaboration is the keystone of BioAtla's long-term plans to address the growing high demand for innovative therapeutic products in the China pharmaceutical market. BioAtla's patent protected Conditionally Active Biologics platform represents a disruptive technology for the development of a powerful new class of immunotherapeutics that are activated in selected microenvironments within the body, such as those indicative of cancerous tumors. CABs can be generated in several different formats including naked monoclonal antibodies (mAbs), antibody drug conjugates, immune checkpoint inhibitors, bispecific antibodies, and chimeric antigen receptor (CAR) T cells.

"BioAtla's strategy is to broadly and rapidly pursue novel therapeutic products based on our patented CAB and other proprietary technologies," said Jay M. Short, Ph.D., president, chief executive officer and chairman of the board of BioAtla. "China is an immensely important opportunity for CABs and we are excited to be working with Sinobioway with its demonstrated commitment and strong capabilities to execute and to fulfill our mutual goals. Since BioAtla's founding in 2007, we have utilized our San Diego and Beijing development and operations capabilities to successfully develop dozens of protein products under contract and shared development. We will continue to build upon our drug development experience to pursue the great prospects of the CAB platform for our collaboration with Sinobioway, as well as for our collaboration with Pfizer that we announced last month on December 8, and for our portfolio of proprietary CAB products."

"Conditionally Active Biologics is an innovative and breakthrough technology to develop the new class of immuno-oncology therapeutics," said Dr. Pan Aihua, chairman of Sinobioway.  "The CAB technology and its prospects will be important elements in Sinobioway's mission to advance science and industrial development, and improve health in China through creating and delivering safer and more effective medicines to patients." 

About Conditionally Active Biologics (CABs)

Conditionally Active Biologic proteins are generated using BioAtla's proprietary protein evolution and expression technologies. These proteins can be mAbs, enzymes and other proteins designed with functions dependent on changes in microphysiological conditions (e.g., pH level, oxidation, temperature, pressure, presence of certain ions, hydrophobicity and combinations thereof).

Studies have shown that cancerous tumors create highly specific conditions at their site that are not present in normal tissue. These cancerous microenvironments are primarily a result of the well understood unique glycolytic metabolism associated with cancer cells, referred to as the Warburg Effect, which was first described in the early 1900's and is the basis of the widely-used PET scan cancer detection method today. CAB-designed mAbs can be programmed to deliver their therapeutic payload and/or recruit the immune response in specific and selected locations and conditions within the body. CABs increase safety because the drug's activation depends on its presence in a particular cellular microenvironment thereby preferentially binding to its intended target protein in the area of disease. In addition, the activation is reversible and can repeatedly switch 'on and off' should the CAB product move from a diseased to a normal cellular microenvironment and vice versa thereby further reducing chances the CAB would bind to the same protein located in healthy tissue or in other parts of the body and cause undesirable toxicity.

CABs allow for higher dosing, the development of effective, non-immunogenic drugs, and the use of targets that are validated for cancer cells but traditionally considered too prevalent among normal cells to be used safely in current drug therapies. This opens a potentially rich range of targets for CABs that cannot be addressed using existing technologies. CABs may also be employed as diagnostic tools to reveal and pinpoint conditions indicative of cancerous activity.
