Briacell Therapeutics Corp.’s subsidiary, Briapro Therapeutics Corp., is developing novel, high affinity antibodies to B7-H3 using molecular modeling techniques. As both an immune checkpoint molecule that regulates T-cell activity and a cell surface molecule expressed on many types of cancer cells, B7-H3 is a promising drug target.
Although CD19-directed CAR T cells can initially induce remission in 70-90% of patients with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL), post-CAR relapses are frequent. These relapses are driven by insufficient persistence of CAR T cells, allowing for antigen-positive B-ALL re-emergence and loss of the targeted epitope either in isolation or as part of lineage-switching.
Pancreatic ductal adenocarcinom a (PDAC), frequently detected at advanced stages, has a 5-year survival rate of 12%. Metastases are common, including hepatic metastasis, which is particularly lethal due to the liver’s immune-tolerant environment and rich blood supply that facilitate tumor growth.
Curevac NV announced that the FDA has cleared its IND application for a phase I clinical study of CVHNLC in patients with squamous non-small-cell lung cancer (sqNSCLC). CVHNLC is Curevac’s investigational mRNA-based precision immunotherapy.
Tharimmune Inc. has announced preclinical data from its expanded pipeline with HS-1940, a dual-target multispecific biologic engineered to bind to both programmed cell death protein 1 (PD-1) and vascular endothelial growth factor (VEGF), and HS-3215, a dual-target biologic binding to HER2 and HER3 receptors. Both use the proprietary Epiclick technology, a multispecific antibody engineering platform.
ALX Oncology Holdings Inc. has received FDA clearance for the IND application for ALX-2004, the company’s potential best- and first-in-class antibody-drug conjugate (ADC) for the treatment of epidermal growth factor receptor (EGFR)-expressing solid tumors.
AT-rich interactive domain-containing protein 1A (ARID1A) encodes a switch/sucrose nonfermentable (SWI/SNF) complex and is mutated in around 10% of colorectal cancers. ARID1A deficiency damages DNA damage repair increasing tumor mutation burden in ovarian and gastrointestinal cancers.
Although CAR T-cell therapies have reached significant clinical success in hematological malignancies, their utility in solid tumors remains limited. One of the main challenges is the scarcity of truly cancer-specific antigens for precise targeting of solid tumors. The use of engineered small, specific antigen-binding domains, such as nanobodies, could be a potential strategy to improve the specificity and efficacy of CAR T cells against solid tumors.
Sun Pharma Advanced Research Co. Ltd. has filed an IND application with the FDA for SBO-154 for the treatment of solid tumors. A global phase I study is planned in advanced solid tumors.
Immune checkpoint inhibitors (ICIs) are monoclonal antibodies activating the immune system to kill tumor cells, representing a major advancement in cancer treatment. However, by activating T-cell immunity, ICI treatment can lead to immune-related adverse events affecting the several organs, including the heart.
