Immune Checkpoint Inhibitor
||Tecentriq (atezolizumab) is a monoclonal antibody against PD-L1 (CD274), preventing activation of its receptor, potentially enhancing T-cell-mediated immune response to neoplasms and inhibiting T-cell inactivation (PMID: 29449897). Tecentriq (atezolizumab) is FDA approved for use in patients with advanced urothelial carcinoma, metastatic non-small cell lung cancer (NSCLC) progressed on platinum-containing therapy, in combination with bevacizumab, paclitaxel, and carboplatin for non-squamous NSCLC with no EGFR or ALK aberrations, in combination with paclitaxel protein-bound for advanced or metastatic triple-negative breast cancer expressing PD-L1, and in combination with carboplatin and etoposide for small cell lung cancer (FDA.gov).
MEK inhibitor (Pan)
||Cotellic (cobimetinib) is an allosteric inhibitor of MEK1/2, resulting in inhibition of extracellular signal-related kinase 2 (ERK2) phosphorylation and activation and decreased tumor cell proliferation (PMID: 22084396, PMID: 27956260). Cotellic (cobimetinib) is FDA approved for melanoma patients with BRAF V600E or V600K, in combination with Zelboraf (vemurafenib) (FDA.gov).
RAF Inhibitor (Pan)
||Zelboraf (vemurafenib) inhibits BRAF V600E, wild-type BRAF, ARAF, and CRAF (PMID: 20179705), which may result in an inhibition of the MAPK signaling pathway resulting in a reduction of tumor cell proliferation (PMID: 20823850). Zelboraf (vemurafenib) is FDA approved for BRAF V600E-mutant melanoma and for BRAF V600-positive Erdheim-Chester disease (FDA.gov).
