About TST005
TST005, is a bi-functional anti-PD-L1 and TGF-β trap fusion protein designed to simultaneously target two immuno-suppressive pathways, transforming growth factor β-(TGF-β) and programmed cell death ligand-1 (PD-L1), that are commonly used by cancer cells to evade the immune system. TST005 consists of a high affinity PD-L1 antibody fused with an engineered TGF-β Receptor Type II protein in its C-terminal. TST005 lacks FcR binding and has reduced risk of FcR mediated killing of PD-L1 expressing effector T cells. TST005’s PD-L1 high binding activity and enhanced TGF-β trap stability enables the targeted delivery of TGF-β trap into PD-L1 expressing tumors, thereby minimizing off-target toxicities of systemic inhibition of TGF-β signaling. TST005 displayed potent activity in vitro in reversing TGF-β induced T-cell suppression. In multiple syngeneic tumor models, TST005 induced significant increase of CD8 T-cell infiltration into PD-L1 expressing tumors and displayed dose-dependent tumor growth inhibition. TST005 is well tolerated in non-human primates and displayed a linear PK profile. TST005 is a potential novel bi-functional immunotherapy candidate with improved therapeutic window.

On April 15, 2021 Prestige BioPharma and Pharmapark LLC reported that the two companies have entered into a binding agreement for the exclusive partnership and supply for the commercialization of Prestige BioPharma’s Bevacizumab biosimilar in the Russian Federation (Press release, Prestige BioPharma, APR 15, 2021, View Source [SID1234578099]).

Prestige’s Bevacizumab (HD204) is a mAb biosimilar to Roche’s Avastin, an inhibitor of vascular endothelial growth factor (VEGF), which is used in combination with other therapies to treat patients with multiple forms of cancer including metastatic colorectal cancer, advanced non-small-cell lung cancer, advanced kidney cancer, certain types of epithelial cancers and cancers of the cervix. HD204 is currently in Phase III clinical development with active recruitment ongoing within the pivotal efficacy and safety trial SAMSON-II. Positive results were previously reported from the Phase I clinical trial (SAMSON-I) which evaluated the pharmacokinetics, safety and immunogenicity of HD204 to Avastin.

The partnership arrangement includes the exclusive rights for Pharmapark to commercialize the Bevacizumab biosimilar in the Russian Federation, leveraging the company’s strong sales and marketing capabilities and experience in successfully bringing new biosimilars to market. Whilst the terms of the deal are not being disclosed, Prestige BioPharma will assume responsibility for product commercial supply out of its manufacturing facilities in Osong, Korea, while Pharmapark will be responsible for local registration, sales and marketing in the Russian Federation with the option to manufacture the product in Russian Federation in line with the Russian import substitution strategy.

This agreement expands upon the existing collaboration between Prestige BioPharma and Pharmapark LLC with the companies signing a license agreement in July 2019 for Prestige BioPharma’s Herceptin biosimilar.

On April 15, 2021 Brooklyn ImmunoTherapeutics, Inc. (NYSE American: BTX) ("Brooklyn"), a biopharmaceutical company focused on exploring the role that cytokine-based therapy can have in treating patients with cancer, reported it has paid $1 million towards the acquisition of a license for Factor Bioscience’s and Novellus’ mRNA Gene Editing and Cell Therapies technology and has extended through May 21, 2021 its option exercise period for entering into a related license agreement with Factor Bioscience and Novellus (Press release, Brooklyn ImmunoTherapeutics, APR 15, 2021, View Source [SID1234578098]).

If a license agreement is completed, it would allow Brooklyn to utilize an extensively patented process to seek to develop gene edited compounds using mRNA, which preclinical data suggest to be more efficient, non-immunogenic and non-mutagenic, for treatment of several solid tumor and liquid indications, sickle cell anemia, as well as a number of additional inherited disorders. Gene editing is an investigational technique that is used to add, delete, or correct a patient’s genetic material in an effort to treat a disease. Research suggests that editing genes in patients could potentially result in cures for a number of genetic diseases. The licensed platform would include mRNA cell reprogramming, mRNA-based gene editing, a proprietary gene editing protein, and the proprietary ToRNAdo lipid delivery system that provides efficient delivery of mRNA ex vivo and in vivo to skin, brain, eye and lung tissue.

If Brooklyn does not enter into the license agreement by May 21, 2021, it will be entitled to be reimbursed for the $1 million payment.
