The cobas® 4800 BRAF V600 Mutation 76 Test is a real-time PCR test on the cobas 4800 system, and is intended to be used as an aid in selecting melanoma patients whose tumors 77 carry the BRAF V600E mutation for treatment with vemurafenib. 78 SUMMARY AND EXPLANATION OF THE TEST 79 Activating mutations of the proto-oncogene BRAF occur in many human cancers, including malignant melanoma, colorectal cancer, 3 80 ovarian cancer, and thyroid cancer. 1,2 BRAF mutations have been identified in 40%-60% of malignant melanomas. Mutations are also 81 common in benign nevi,4 suggesting that such mutations are a very early event. The discovery of such somatic mutations in the BRAF 82 gene in melanoma and other human tumors has helped to elucidate the central role of the BRAT kinase in signaling pathways that 83 control cellular proliferation, differentiation and cell death. In normal cells, BRAF is part of a highly regulated signaling pathway that 84 mediates the effects of growth factor receptors (such as EGFR) through RAS. RAF, MEK and ERK. Oncogenic mutations in BRAF 85 result in a gain of kinase function, rendering the RAF-MEK-ERK pathway constitutively active in the absence of the typical growth 86 factors. 87 The majority of BRAF mutations in melanoma and other human tumors occur in codon 600.' The predominant mutation at codon 600 is 88 the V600E mutation (GTG>GAG). A number of dinucleotide mutations affecting codon 600 [V600K (GTG>AAG), V600R 89 (GTG>AGG), V600E2 (GTG>GAA), and V600D (GTG>GAT)] have also been observed less commonly, primarily in melanoma and 90 rarely in other tumors, such as colorectal cancer. The cobas' 4800 BRAF V600 Mutation Test is a real-time PCR assay designed to 91 detect the presence of the V600E (T1799A) mutation. The cobas" 4800 BRAF V600 Test is used as a companion diagnostic test for 92 vemurafenib, a compound which inhibits the mutant V600E version of BRAF. Clinical trials of vemurafenib in patients with advanced 93 melanoma have shown that patients with a V600E-mutant tumor are likely-to experience clinical benefit from the compound67. 94 PRINCIPLES OF THE PROCEDURE 95 The cobas® 4800 BRAF V600 Mutation Test is based on two processes: (1) manual specimen preparation to obtain genomic DNA from 96 formalin-fixed, paraffin-embedded tissue (FFPET); (2) PCR amplification and detection of target DNA using a complementary primer 97 pair and two oligonucleotide probes labeled with different fluorescent dyes. One probe is designed to detect the wild-type BRAF V600 98 sequence and one is designed to detect the V600E mutation sequence. Two external run controls are provided and the wild-type allele 99 serves as an internal, full process control. 100 Specimen Preparation 101 FFPET specimens are processed and genomic DNA isolated using the cobas®

Abstract: Oncogenic RAS (Rat sarcoma) mutations drive more than half of human cancers, and RAS inhibition is the holy grail of oncology. Thirty years of relentless efforts and harsh disappointments have taught us about the intricacies of oncogenic RAS signalling that allow us to now get a pharma- cological grip on this elusive protein. The inhibition of effector pathways, such as the RAF-MEK-ERK pathway, has largely proven disappointing. Thus far, most of these efforts were aimed at blocking the activation of ERK. Here, we discuss RAF-dependent pathways that are regulated through RAF functions independent of catalytic activity and their potential role as targets to block oncogenic RAS signalling. We focus on the now well documented roles of RAF kinase-independent functions in apoptosis, cell cycle progression and cell migration.

However, recent advances in drug development have allowed a significative improvement in prognosis. In particular, BRAF/MEK inhibitors and anti-PD1 antibodies have completely revolutionized the management of this disease. Nonetheless, not all patients derive a benefit or a durable benefit from these therapies. To overtake this challenges, new clinically active compounds are being tested in the context of clinical trials. CDK4/6 inhibitors are drugs already available in clinical practice and preliminary evidence showed a promising activity also in melanoma. Herein we review the available literature to depict a comprehensive landscape about CDK4/6 inhibitors in melanoma. We present the molecular and genetic background that might justify the usage of these drugs, the preclinical evidence, the clinical available data, and the most promising ongoing clinical trials.

Simple Summary: Cyclin-dependent kinases 4 and 6 (CDK4/6) are key enzymes controlling the cell cycle. CDK4/6 inhibitors are being tested in multiple clinical trials for a range of cancers including melanoma, and a deeper understanding of how they interact with other therapies is vital for their clinical development. Beyond the cell cycle, CDK4/6 regulates cell metabolism, which is a critical factor determining response to standard-of-care mitogen-activated protein kinase (MAPK) pathway therapies in melanoma. Here, we show that CDK4/6 inhibitors increase glutamine and fatty acid-oxidation-dependent mitochondrial metabolism in melanoma cells, but they do not alter the metabolic response to MAPK inhibitors. These observations shed light on how CDK4/6 inhibitors Citation: Santiappillai, N.T.; impinge on the regulation of metabolism and how they interact with other therapies in the setting of Abuhammad, S.; Slater, A.; Kirby, L.; melanoma.

Despite significant advances, targeted therapy is greatly limited by resistance acquisition, which emerges in nearly all patients receiving treatment. As a result, identifying the molecular modulators of resistance is of great interest. Recent work has implicated protein kinase C (PKC) isozymes as mediators of drug resistance in non-small cell lung cancer (NSCLC). Importantly, previous findings on PKC have implicated this family of enzymes in both tumor-promotive and tumor-suppressive biology in various tissues. Here, we review the biological role of PKC isozymes in NSCLC through extensive analysis of cell-line-based studies to better understand the rationale for PKC inhibition.

  • CRAF Mutations in Lung Cancer Can Be Oncogenic and Predict Sensitivity to Combined Type II RAF and MEK Inhibition

This article is published with open access Abstract Two out of 41 non-small cell lung cancer patients enrolled in a clinical study were found with a somatic CRAF mutation in their tumor, namely CRAFP261A and CRAFP207S. To our knowledge, both mutations are novel in lung cancer and CRAFP261A has not been previously reported in cancer. Expression of CRAFP261A in HEK293T cells and BEAS-2B lung epithelial cells led to increased ERK pathway activation in a dimer-dependent manner, accompanied with loss of CRAF phosphorylation at the negative regulatory S259 residue. Moreover, stable expression of CRAFP261A in mouse embryonic fibroblasts and BEAS- 1234567890();,: 1234567890();,: 2B cells led to anchorage-independent growth. Consistent with a previous report, we could not observe a gain-of-function with CRAFP207S. Type II but not type I RAF inhibitors suppressed the CRAFP261A-induced ERK pathway activity in BEAS- 2B cells, and combinatorial treatment with type II RAF inhibitors and a MEK inhibitor led to a stronger ERK pathway inhibition and growth arrest.

Mills , Jeffrey Field8, Jessie Villanueva2, Xiaowei Xu9, Meenhard Herlyn 2 and Wei Guo 1 © The Author(s) 2021 Targeting MAPK pathway using a combination of BRAF and MEK inhibitors is an efficient strategy to treat melanoma harboring BRAF-mutation. The development of acquired resistance is inevitable due to the signaling pathway rewiring. Combining western blotting, immunohistochemistry, and reverse phase protein array (RPPA), we aim to understanding the role of the mTORC1 signaling pathway, a center node of intracellular signaling network, in mediating drug resistance of BRAF-mutant melanoma to the combination of BRAF inhibitor (BRAFi) and MEK inhibitor (MEKi) therapy. The mTORC1 signaling pathway is initially suppressed by BRAFi and MEKi combination in melanoma but rebounds overtime after tumors acquire resistance to the combination therapy (CR) as assayed in cultured cells and PDX models. In vitro experiments showed that a subset of CR melanoma cells was sensitive to mTORC1 inhibition. The mTOR inhibitors, rapamycin and NVP-BEZ235, induced cell cycle arrest and apoptosis in CR cell lines. As a proof-of-principle, we demonstrated that rapamycin and NVP-BEZ235 treatment reduced tumor growth in CR xenograft models. Mechanistically, AKT or ERK contributes to the activation of mTORC1 in CR cells, depending on PTEN status of these cells.

Downloaded From: https://jamanetwork.com/ on 09/30/2021 eMethods Whole exome sequencing Whole exome capture libraries for both tumor and normal samples were constructed using 100ng genomic DNA input and following the protocol as described by Fisher et al.,3 with the following adapter modification: Illumina paired end adapters were replaced with palindromic forked adapters with unique 8 base index sequences embedded within the adapter. In-solution hybrid selection was performed using the Illumina Rapid Capture Exome enrichment kit with 38Mb target territory (29Mb baited). The targeted region includes 98.3% of the intervals in the Refseq exome database. Dual-indexed libraries were pooled into groups of up to 96 samples prior to hybridization.
