CELL AND GENE THERAPY
Mnemo Therapeutics | January 24, 2022
The journal Nature Medicine recently published a study in which researchers developed a novel receptor to enhance recognition of tumors by engineered T cells, addressing an underlying cause for relapsed tumors in patients after chimeric antigen receptor therapy. The study demonstrates high antigen sensitivity of HLA-independent T-cell receptors, created by editing the TCR Alpha Constant chain locus in human peripheralbio blood Tcells.
Low antigen expression
One major limitation of CARs is antigen escape, when a tumor no longer expresses the antigen detectable by the CARs or expresses them at a very low level; CARs with heightened sensitivity to low-expression level antigens boosts the efficacy of otherwise promising T-cell therapies.
In the study, conducted by researchers at New York's Memorial Sloan Kettering Cancer Center, researchers produced HIT T-cells and analyzed them in animal models
HIT T-cells were engineered from human peripheral blood T-cells by inserting variable region genes in the TRAC locus, endowing the cell with a single specificity for a target antigen such as CD19. Notably, this sensitivity was shown to be higher than traditional CARs for low levels of antigen expression resulting in superior cytotoxicity and cytokine secretion.
HIT Tcells outperformed traditional CAR T-cells in vivo in mouse models of B cell leukemia and acute myeloid leukemia, without costimulation. Coexpression of HIT with CD80 and 4-1BBL further augmented therapeutic activity and mouse survival.
HIT T-cells are a promising therapy for targeting cancer cell surface antigens with low abundance due to their sensitivity and persistence.
The team responsible for this important work includes MSKCC researcher and Mnemo Therapeutics scientific cofounder Michel Sadelain, M.D., Ph.D., MSKCC researcher and Mnemo scientific advisor Isabelle Rivière, Ph.D., as well as Justin Eyquem, Ph.D., University of California San Franciso and Mnemo scientific cofounder.
Mnemo's EnfiniT Platform
These findings support Mnemo's EnfiniT platform as the next-generation toolkit for CAR-T immunotherapies, which are founded on decades of breakthrough research from Institut Curie and MSKCC, and supported with best-in-class T-cell manufacturing. The EnfiniT platform brings together a suite of technologies to address the key challenges associated with CAR T therapies by both identifying a new class of antigens with greater tumor specificity and applying a range of technologies to significantly improve T-cell memory, persistence and sensitivity. The goal is to dramatically improve the body's ability to fight and overcome disease.

CELL AND GENE THERAPY
BioInvent | December 22, 2020
BioInvent International AB ("BioInvent") (OMXS: BINV), a biotech organization focused in on the discovery and development of novel and first-in-class immune-modulatory antibodies for cancer immunotherapy, and Transgene (Euronext Paris: TNG), a biotech organization that designs and develops infection based for the therapy of cancer, reported they have received administrative endorsement in Belgium for a clinical trial application (CTA) for a Phase l/lla study of the novel oncolytic vaccinia virus BT-001.
BT-001 is a best-in-class oncolytic Vaccinia virus. It has been produced utilizing Transgene's Invir.IO™ stage and its protected large-capacity VVcopTK-RR-oncolytic virus, which has been designed to encode both a Treg- depleting human recombinant anti-CTLA4 antibody response created by BioInvent's proprietary n-CoDeR®/F.I.R.S.T™ stages, and the human GM-CSF cytokine. By specifically focusing on the tumor microenvironment, BT-001 is relied upon to inspire a lot more grounded and more successful antitumoral reaction. Conveying the anti-CTLA4 antibody response straightforwardly to the tumor microenvironment will permit a neighborhood remedial movement and will in this manner enormously increment the security and tolerability profile of the monoclonal immunizer by antibody foundational introduction. BT-001 is being co-created through a 50/50 collaboration among BioInvent and Transgene.
TurtleTree | October 04, 2021
TurtleTree has officially opened its new R&D facility in California's state capital. Located in West Sacramento, this 24,000-square-foot building will house a world-class research hub showcasing the company's extensive array of innovations and cell-based technologies.
Representing a milestone in TurtleTree's US-based expansion plans, the research facility will spur the development of precision fermentation technology currently used to produce valuable milk ingredients like lactoferrin. This marks a significant stride towards the production of consumer-ready milk and dairy, reaffirming TurtleTree's status as a leading player in the field of sustainable nutrition.
In addition to improving these capabilities, the establishment of this groundbreaking facility will also further TurtleTree's mission of uplifting the world beyond the creation of sustainable food. To adequately staff the facility, the company will create approximately 40 new tech-related jobs in and around Greater Sacramento. These will span diverse fields from food science to engineering, yielding fresh opportunities for seasoned professionals and fresh graduates alike.
Referencing this positive impact, TurtleTree's CEO and co-founder, Fengru Lin, stated: "Establishing this R&D facility in Greater Sacramento marks the first step towards bringing our unique products from development to market—one that we're very glad will help unlock new opportunities within the local community. We're eagerly looking forward to working with the brilliant talent in the area and building a future generation of nutrition that we can all enjoy for decades to come."
Echoing similar sentiments, various West Sacramento representatives have also offered their support for the new facility. President and CEO of the Greater Sacramento Economic Council, Barry Broome, stated: "We want to congratulate TurtleTree for locating their R&D and manufacturing facility in West Sacramento. This move signals market validation of why Greater Sacramento is world-class in biotech, specifically alternative proteins research."
West Sacramento is honored to have been chosen by TurtleTree as the location for their much-anticipated research facility. The city looks forward to assisting the TurtleTree leadership to achieve their goals, with respect to the facility, through an accelerated occupancy permit process, TurtleTree is making significant contributions to a sustainable, global food supply and is also creating opportunities to prepare future generations to continue this important scientific work through our student internship program, which will be of great benefit to the city's youth.
-West Sacramento mayor, Martha Guerrero
Moving forward, TurtleTree remains committed to its role in developing the food and agriculture ecosystem in Northern California. Aside from functioning as a research hub, the R&D facility will also serve as an integral touchpoint for TurtleTree to connect and collaborate with educational institutions, research-focused partners, strategic partners, future customers, and investors.
TurtleTree is a biotech company that's using cell-based technologies to create sustainable food and dairy. In spite of this, we earnestly believe that what we do extends beyond the dining table and into the heart of humanity. At our core, we seek to uplift the world by providing a new generation of nutrition that's better for the planet, better for the animals, and better for people everywhere.
