mRNA-5671 also known as V941 is a cancer vaccine candidate developed by Moderna. [1] It is a tetravalent vaccine that targets G12D, G12V, G13D or G12C driver mutations in the KRAS gene. [ 2 ] It is currently being evaluated for the treatment of either non-small cell lung cancer , colorectal cancers with microsatellite instability , or ...
Patients who harbor an EGFR mutation have a 60% response rate to erlotinib. However, the mutation of KRAS and EGFR are generally mutually exclusive. [29] [30] [31] Lung cancer patients who are positive for KRAS mutation (and the EGFR status would be wild type) have a low response rate to erlotinib or gefitinib estimated at 5% or less. [29]
K-Ras(G12C) inhibitor 6 is an irreversible inhibitor of oncogenic K-Ras(G12C), subverting the native nucleotide preference to favour GDP over GTP.Its family of inhibitors allosterically control GTP affinity and effector interactions by fitting inside a "pocket", or binding site, of mutant K-Ras.
Sotorasib, sold under the brand names Lumakras and Lumykras, is an anti-cancer medication used to treat non-small-cell lung cancer. [4] [5] It targets a specific mutation, G12C, in the protein K-Ras encoded by gene KRAS which is responsible for various forms of cancer. [7] [8] Sotorasib is an inhibitor of the RAS GTPase family.

Lewis lung carcinoma is a hypermutated Kras/Nras–mutant cancer with extensive regional mutation clusters in its genome. A tumor that spontaneously developed as an epidermoid carcinoma in the lung of a C57BL mouse. It was discovered in 1951 by Dr. Margaret Lewis of the Wistar Institute and became one of the first transplantable tumors. [1]
About 2% of all lung cancers are non-carcinoma (mainly sarcoma, tumors of hematopoietic origin, or germ cell tumors. [5] These forms of lung cancer are usually treated differently from carcinomas. Because of the ubiquity of lung carcinomas, however, the term "lung cancer" generally refers to carcinomas in everyday clinical practice. [citation ...
Chemotherapy for NSCLC usually includes combination of two drugs (chemotherapy doublet), with one of the agents is cisplatin or carboplatin. In 2002, Schiller at al. published in the New England Journal of Medicine, a study that compared four chemotherapy regimens for advanced NSCLC, cisplatin and paclitaxel, cisplatin and gemcitabine, cisplatin and docetaxel, and carboplatin and paclitaxel. [14]
However, as SCL are considered particularly aggressive non-small cell lung cancers, [2] some experts recommend particularly aggressive treatment approach to these tumors. Little is known about the effects of EGFR inhibitors in SC, although some evidence suggests that these tumors are not likely to be highly responsive.
