BAT7104 was designed to inhibit the PD-1/PD-L1 and CD47/SIRP-α pathways. By an "imbalanced" design with finely tuned binding affinity to CD47 and high affinity to PD-L1, BAT7104 is expected to avoid RBC depletion and block CD47 on CD47+/PD-L1+ tumors in a more selective and tumor-enriched manner. BAT7104 was shown to effectively inhibit both pathways in vitro and demonstrated synergistic activity in inducing complete tumor regression in vivo. In non-human primates (NHP) study, BAT7104 was well tolerated with no adverse effects, suggesting a favorable therapeutic index in future clinical development. "BAT7104 has demonstrated higher anti-tumor activity with better safety profile in preclinical studies". Commented Dr. Shengfeng Li, CEO, Bio-Thera Solutions. "As the first bispecific antibody of Bio-Thera, we are pleased to see BAT7104 enter clinical development in Australia, and we will continue bringing more innovative anti-tumor drugs to cancer patients." Dr. Shengfeng Li continued.

The Phase 1, multi-center, open-label, dose-escalation clinical trial of BAT7104 is designed to assess the safety and tolerability of BAT7104. Key objectives of the study are to determine the maximum tolerated dose and recommended Phase 2 dose (RP2D), and to evaluate pharmacokinetics and preliminary efficacy in patients with advanced solid tumor. Another early stage Phase 1 clinical study evaluating BAT7104 is being conducted in China in patients with solid tumors and lymphoma. In addition, Bio-Thera Solutions is developing several additional innovative oncology assets directed at important IO targets, including PD-1, OX40, CTLA-4, and TIGIT, all in early stage clinical studies.

On May 9, 2022 Twist Bioscience Corporation (NASDAQ: TWST), a company enabling customers to succeed through its offering of high-quality synthetic DNA using its silicon platform, reported it has entered into a research collaboration and exclusive option license agreement with Astellas Pharma Inc (Press release, Twist Bioscience, MAY 9, 2022, View Source [SID1234613958]). Under the terms of the agreement, the companies will jointly conduct research activities to identify and optimize proprietary Twist antagonist antibodies, targeting an undisclosed checkpoint inhibitor pathway in the tumor microenvironment (TME), as potential therapeutic development candidates. Ligands in this pathway are found in relatively high concentrations in the tumor microenvironment. Blocking the receptor’s activation has the potential to markedly enhance anti-tumor immunity with other Astellas therapies including chimeric antigen receptor-based (CAR) technologies combined with Universal Donor Cells. Astellas will have the exclusive option to license any development candidates generated as part of the collaboration.

"Our robust antibody discovery and optimization capabilities uniquely position us to develop antibodies with high affinity and specificity for historically difficult targets, such as those mediating immune suppression in the TME," said Emily M. Leproust, Ph.D., CEO and co-founder of Twist Bioscience. "This out-licensing agreement validates the capabilities of Twist-generated antibodies to enable the discovery and advancement of next generation therapies. As the first out-licensing agreement for Twist Biopharma, this deal will serve as an initial base that we intend to build on as we pursue increasingly larger and later stage out-licensing opportunities with additional partners and targets."

Targeting this pathway with antibody therapeutics is a novel approach with no antibodies in clinical development. Developing next-generation checkpoint inhibitor immunotherapies using new modalities is promising as an innovative healthcare solution. Through this collaboration we expect to stimulate a highly specific and targeted attack on cancer cells by optimizing these development candidates, and leveraging Astellas’ flexible convertibleCAR cell therapy technology.

Under the terms of the agreement, Twist will receive an upfront payment from Astellas as well as an additional payment upon the exercise of the licensing option. Twist will receive payments connected to success-based clinical milestones as well as royalty payments on product sales for each licensed product. Astellas will be responsible for the development, manufacturing and commercialization of any licensed products.
