CAR T-cell immunotherapy is designed with different targets depending on the receptors they will bind to. CARs can also contain different tools, like the concept of a Swiss army knife, with several utensils for different tasks. The goal is to make them more effective and durable. During the second session of the Spotlight on Immuno-Oncology conference, “Novel CAR designs and approaches,” Robbie Majzner, of Stanford University, described expanding the main components of CAR T cells to acquire new functions and act on different cell pathways.
“From such a stick, such a splinter,” is a popular Spanish saying to explain how a son resembles his father. Like father, like son. The first Spotlight on Immuno-Oncology conference of the American Society of Gene & Cell Therapy (ASGCT) is the splinter of the ASGCT annual meeting, which brought together a group of experts in this field. It took place on Aug. 1 and 2, 2023, starting with a series of talks on “B Cell Malignancies and Beyond.”
Avencell Therapeutics Inc. has received approval from the EMA for its clinical trial application (CTA) for AVC-201 for the treatment of relapsed/refractory acute myeloid leukemia (AML) and other selected hematologic malignancies positive for CD123. A phase I study will be conducted in Germany.
After CAR T-cell immunotherapy for leukemia, some children have a longer remission because the engineered cells remain active and control or prevent the growth of new tumor cells. A new collaborative study has found that these persistent cells expressed certain genes that could be identified through a transcriptional signature. The finding could explain why the treatment does not work in some patients, and potentially help to improve it, reducing relapses.
Maxcyte Inc. and Vittoria Biotherapeutics Inc. have signed a strategic platform license agreement for use of Maxcyte’s Flow Electroporation technology and Expert platform by Vittoria Biotherapeutics. Under the agreement, Vittoria will obtain nonexclusive clinical and commercial rights to use Maxcyte’s Flow Electroporation technology and Expert platform, and will pay Maxcyte platform licensing fees and program-related revenue.
Poseida Therapeutics Inc. has received FDA clearance of its IND application for P-CD19CD20-ALLO1, an allogeneic dual chimeric antigen receptor (CAR) T-cell product candidate being developed for relapsed or refractory B-cell malignancies in partnership with F. Hoffmann-La Roche Ltd. The company is actively focused on opening clinical sites for a phase I study in adults with relapsed or refractory B-cell malignancies.
Coimmune Inc. has obtained a license to target delta-like ligand 3 (DLL3) with IL-18 armored chimeric antigen receptor (CAR) technology. The company exercised an option to obtain an exclusive license in the DLL3-targeted, allogeneic CAR-cytokine induced killer (CAR-CIK) cell therapy field to IL-18 armored CAR technology under an agreement with Memorial Sloan Kettering Cancer Center (MSK).
Panbela Therapeutics Inc. has entered into a sponsored research agreement with The University of Texas MD Anderson Cancer Center for the evaluation of polyamine metabolic inhibitor...
Part of the reason for CAR T cells’ astonishing success in B-cell cancers is that B cells are astonishingly easy to replace. CAR T cells are specific, yes. But they are not specific to tumor cells. They are specific to their target antigens. In the case of Yescarta (axicabtagene ciloleucel, Gilead Sciences Inc.) and Kymriah (tisagenlecleucel, Novartis AG), the first two clinically approved T cells, that target is CD19, which is expressed on B-cell precursors. And when it is successful, the treatment leaves patients without any B cells at all.
