WebIt is an inhibitor of the B-Raf enzyme and was developed by Plexxikon. Mechanism of action. Vemurafenib causes programmed cell death in melanoma cell lines. Vemurafenib interrupts the B-Raf/MEK step on the B-Raf/MEK/ERK pathway − if the B-Raf has the common V600E mutation. WebAlthough BRAF inhibitor monotherapy yields response rates >50% in BRAF V600-mutant melanoma, only approximately 5% of patients with BRAF V600E colorectal cancer respond. Preclinical studies suggest that the lack of efficacy in BRAF V600E colorectal cancer is due to adaptive feedback reactivation of MAPK signaling, often mediated by EGFR. This …

WebApr 14, 2024 · Abstract. Background Inhibitors of the EGFR-RAS-RAF-MEK (MAPK) pathway have been successfully developed to treat cancers. However, many patients do not benefit from these inhibitors due to primary or acquired resistance. In colorectal cancer (CRC), resistance to inhibitors of the MAPK pathway is especially prominent, reflected … WebJan 7, 2024 · Rationale: Combined treatment with dabrafenib, a B-RAF inhibitor, and trametinib, a mitogen-activated protein kinase inhibitor, is an effective option for patients with metastatic melanoma. A few cases of acute kidney injury associated with tubulointerstitial nephritis and 1 case of nephrotic syndrome have been reported in … WebFeb 8, 2016 · RAF inhibitors were the first therapeutics in this pathway to show clinical benefit 1, 2. One might expect that isozyme selectivity, i.e. compounds specific for BRAF over CRAF or ARAF would be necessary for tolerability. But the first few compounds like vemurafenib and dabrafenib are not particularly isoform selective. redis age of key
