CELL AND GENE THERAPY
Burixafor | November 09, 2020
TaiGen Biotechnology Company, Limited ("TaiGen") announced today that they have signed an exclusive agreement with GPCR Therapeutics, Inc. ("GPCR"), a leading Korean biotechnology company, for the continued development of Burixafor worldwide and the commercialization of Taigexyn® (nemonoxacin) in South Korea. Burixafor is a highly potent CXCR4 inhibitor currently under clinical development. It can be used as a stem cell mobilizer for hematopoietic stem cell transplantation and a chemosensitizer in hematological and solid tumors. It can also be used for stem cell collection in healthy individuals for personalized regenerative medicine. Taigexyn® is a novel safe and effective antibiotic for the treatment of bacterial infections including those caused by drug-resistant bacteria. Under the terms of the agreement, GPCR Therapeutics will be wholly responsible for the development, registration, and commercialization of Taigexyn® in S. Korea and Burixafor worldwide. Apart from upfront fees, TaiGen will receive shares of GPCR Therapeutics as well as future milestone and royalty payments.
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.

Mogrify | January 11, 2021
Mogrify Limited (Mogrify®), a UK organization expecting to change the advancement of ex vivo cell therapies and pioneer the field of in vivo reconstructing treatments, and the MRC Laboratory of Molecular Biology (LMB), a top notch research lab committed to understanding significant natural cycles at the sub-atomic level, today reported an exploratory examination cooperation. The venture intends to create novel protein articulation frameworks by utilizing late advances in direct cell reconstructing to help improve the creation of proteins which are not delivered adequately well in existing articulation frameworks.
The MOGRIFY® technology will be applied to foresee mixes of record variables to incite trans-separation starting with one cell type then onto the next. The subsequent objective cell types could give analysts improved admittance to significant proteins found in human cell types that are hard to get and take into consideration more efficient protein production.
Mogrify will get admittance to any licensed innovation and skill created during the undertaking, further empowering the commercialization of the innovation in regions of remedial worth. This coordinated effort is a development of the Company's relationship with the MRC LMB and follows the declaration in December 2020 that it had made sure about a restrictive permit from the MRC LMB to an upgraded form of MOGRIFY technology empowering more precise record factor expectations and improved cell transformation viability. In the interest of the MRC, the clinical exploration noble cause LifeArc encouraged the restrictive permit of the new form of Mogrify's center reconstructing stage, and together arranged the legitimate structure to empower a fruitful cooperation between the MRC and Mogrify.
