Bio-Thera Solutions Announces Two Poster Presentations at the 2019 AACR Annual Meeting

The first poster, entitled “BAT8001, a potent anti-HER2 antibody drug conjugate with a novel uncleavable linker to reduce toxicity for patients with HER2-positive tumor,” will highlight Phase I clinical data demonstrating the safety and efficacy of BAT8001 in HER2-positive cancer patients. An abstract of the presentation will be available on AACR website on the day of the presentation.

Presentation details are as follows:

The second poster, entitled “Development of a potent Trop-2 antibody-drug conjugate, BAT8003, for the treatment of Trop-2 positive gastric tumors,” will present preclinical data that highlight advantages of BAT8003 as a potential treatment for gastric cancer patients. The IND for a Phase I clinical trial evaluating the safety and pharmacokinetics of BAT8003 was approved earlier this year by the China NMPA. Dosing of the first patient in this Phase I clinical trial is expected to occur during April 2019. An abstract of the presentation is currently available on AACR website.

Presentation details are as follows:

Copies of both posters will be made available on the Company's website after they are presented.

About BAT8001

BAT8001 is an investigational HER2-ADC being evaluated in multiple tumor types. HER2 is a naturally occurring receptor that is overexpressed in many types of cancer, including breast cancer and gastric cancer. BAT8001 is being developed for use as a single agent and in combination with other agents for the treatment of multiple cancers. BAT8001 is currently being evaluated as a single agent in a Phase III metastatic breast cancer trial and in combination with an anti-PD1 antibody in gastric cancer. Both clinical studies are being run in China.

About BAT8003

BAT8003 is an investigational Trop2-ADC being evaluated in multiple tumor types. Trop-2 is a naturally occurring receptor that is overexpressed in many types of cancer, including triple negative breast cancer and gastric cancer. BAT8003 utilizes Bio-Thera Solutions’ proprietary linker-payload combination, Batansine. The antibody component of BAT8003 is engineered for site-specific conjugation to allow for better control of the ADC DAR, providing a more homogenous product. The linker is non-cleavable ensuring superior delivery of the payload to the cancer cells and improving the safety profile of the ADC. BAT8003 is being developed for use as a single agent and in combination with other agents for the treatment of Trop2 positive cancers. A Phase I clinical trial evaluating the pharmacodynamics and safety of BAT8003 will begin dosing patients during April 2019.
