Immpact Bio USA Inc. has announced clearance of its IND application by the FDA for IMPT-314, a bispecific OR-Gate autologous chimeric antigen receptor (CAR) T-cell therapy targeting the B-cell antigens CD19 and CD20.
The FDA has cleared Cullinan Oncology Inc.'s IND application for CLN-978, a CD19/CD3 T-cell engaging antibody construct with a human serum albumin (HSA) binding domain to increase serum half-life.
Genetically modified derivatives of the chimeric oncolytic virus (OV) CF33 have previously shown cancer selectivity and oncolytic potency against various solid tumors.
Induction of immunogenic cell death (ICD) in cancer has been proposed as a promising strategy to elicit potent adaptive immune responses against tumor-associated antigens, potentially overcoming the limited efficacy of immunotherapy in some patients and tumor types. Since type I interferon (IFN) is a key modulator of ICD in antitumor responses, researchers at the University of California, San Diego are investigating how to expand the IFN effect to promote ICD responses in cancer cells.
While immune checkpoint inhibitors have revolutionized oncology, still only 20-30% of patients respond to PD-1/PD-L1 antibody monotherapy. This can be due to a failure of T cells to recognize “cold” tumors (low T-cell infiltrates).
TANK-binding kinase 1 (TBK1) is a multifunctional serine/threonine kinase with an established role coordinating innate immune responses, and it has been previously identified as a candidate immune evasion gene. Additionally, disrupting TBK1 signaling has shown potential for enhancing response to immunotherapy with immune checkpoint blockade (ICB) in murine tumor models.
