Oncohost Ltd. provided new details on a novel application for its proteomic pattern analysis technology at Biomed Israel last week. While its initial development focused on using a single blood sample to guide selection of first-line immunotherapy for cancer based on likelihood of response, the Prophet platform now also predicts severe adverse immune-related events, Oncohost CEO Ofer Sharon told BioWorld.
Citing a high rate of patients leaving the study, Merck & Co. Inc. has discontinued the anti-TIGIT antibody vibostolimab and the anti-PD-1 Keytruda (pembrolizumab) portion of it phase III Keyvibe-10 trial as an adjuvant treatment for those with resected high-risk melanoma.
China and U.S. biotech Jacobio Pharmaceuticals Group Co. Ltd.’s shares (HKEX:1167) rose nearly 20% after it filed an NDA in China on May 6 for its independently developed KRAS G12C inhibitor, glecirasib (JAB-21822), to treat lung cancer.
Amidst a slew of end-of-week, positive EMA Committee for Medicinal Products for Human Use (CHMP) opinions is Takeda Pharmaceutical Co. Ltd.’s Fruzaqla (fruquintinib). The selective inhibitor of vascular endothelial growth factor receptors-1, -2 and -3 is for adults with previously treated metastatic colorectal cancer.
Chong Kun Dang Pharm (CKD Pharm) has presented data on their c-Met-targeting antibody-drug conjugate (ADC) CKD-703 for the treatment of solid tumors. CKD-703 was designed based on site-specific conjugation, with a stable and homogeneous drug-antibody ratio profile.

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.
Despite GTPase KRAS being the most common mutated oncogene in human cancers, there is still an unmet medical need for treating KRAS G12C-mutated cancers.
Mutations in GTPase KRAS occur in about 25% of human cancers, with the KRAS G12V mutation being one of the most frequent variants, and lead to activation of the MAPK pathway, thus promoting tumorigenesis.
