Prescribing information



BRAF represents a novel therapeutic target for the treatment of advanced non-small cell lung cancer (NSCLC).1


Testing for BRAF in the UK

In England, BRAF testing can now be done as part of the next-generation sequencing (NGS) panel. For more information, go to the national genomic test directory for cancer in England.2

Molecular characterisation of NSCLC marked a turning point in the treatment of lung tumours harbouring kinase alterations suitable for targeted drug inhibition.1

Among patients with driver mutations, outcomes for those treated with targeted therapies are prolonged compared with those who do not receive genotype-directed treatment.3

Mechanism of action of Tafinlar + Mekinist

Tafinlar (dabrafenib) + Mekinist (trametinib) target two different kinases in the MAPK pathway (BRAF and MEK1/2 respectively) to block the signalling that leads to abnormal cell division and growth.6,7

Combination therapy with Tafinlar + Mekinist results in prolonged inhibition of tumour growth compared with either drug alone in BRAF V600E-mutant tumours, both in vitro and in vivo.6,7

ALK, anaplastic lymphoma kinase; BRAF, a human gene that encodes a protein called B-Raf. The gene is also referred to as proto-oncogene B-Raf and v-Raf murine sarcoma viral oncogene homolog B, while the protein is more formally known as serine/threonine-protein kinase B-Raf; EGFR, epidermal growth factor receptor; ERK, extracellular signal-regulated kinases; KRAS, a proto-oncogene that is part of the RAS/MAPK signalling pathway; MAPK, mitogen-activated protein (MAP) kinase; MEK, mekinist; MET, a tyrosine kinase receptor; NSCLC, non-small cell lung cancer; RAS, rat sarcoma; ROS, reactive oxygen species; V600E, mutation of the BRAF gene in which valine (V) is substituted by glutamic acid (E) at amino acid 60; WT, wild type.
