The existence of two approved therapies, Lumakras (sotorasib, Amgen Inc.) and Karzati (adagrasib, Mirati Therapeutics Inc.), has been a triumphant success against KRAS, a protein that was once considered undruggable.
The existence of two approved therapies, Lumakras (sotorasib, Amgen Inc.) and Karzati (adagrasib, Mirati Therapeutics Inc.), has been a triumphant success against KRAS, a protein that was once considered undruggable. KRAS is the most frequently mutated oncogene in solid tumors. KRAS driver mutations are found in about 30% of non-small-cell lung cancers (NSCLC), about half of colorectal cancers, and more than 90% of pancreatic cancers. Lumakras and Karzati both target the G12C mutation. Inhibitors that target other mutations, like G12D, are now making their way through preclinical and clinical development, while some companies are developing therapies that would target mutated KRAS more broadly, irrespective of the specific mutation that is activating the protein.
Amphiphile (AMP)-modification of peptide antigens and molecular adjuvants has been previously demonstrated to enhance lymphatic delivery and retention, resulting in potent expansion of cognate endogenous T-cell responses.
An experimental vaccine that contained antigens of both lytic and latent phases of Epstein-Barr virus (EBV), and induced both an antibody and a T cells response, was able to generate broad and long-lasting immunity against EBV in mouse models of infection. Researchers from the QIMR Berghofer Medical Research Institute and Elicio Therapeutics Inc. reported those results online in Nature Communications on Aug. 8, 2023.
For some viruses, the challenge to developing a vaccine is their rapid mutation rate. This is the major challenge to developing an HIV vaccine or a universal flu vaccine. EBV is different. Its superpower is its ability to hide.
Two companies who needed partners have found each other, as privately held Elicio Therapeutics Inc. will merge with Angion Biomedica Corp. in an all-stock deal.
The Gastrointestinal Research Foundation (GIRF) has launched a new initiative, CA CURE, to identify and fund research to improve diagnostics and develop therapeutics focused on immunotherapies and personalized vaccines for digestive cancers, with a focus on projects that might have difficulty attracting funds because they are too experimental or are in the initial stages of development.
Elicio Therapeutics Inc. CEO Robert Connelly acknowledged "a general malaise about cancer vaccines," but described the strategy of his firm to BioWorld as "very different. None of these other approaches [has] delivered the goods to the lymph nodes, where the immune response is orchestrated."
