Cancer name Non Small Cell Lung Cancer
Cancer Type NSCLC
Immunotherapy type Immune Checkpoint Therapy
Treatment Pembrolizumab
Drugstatus Approved
Drugbank ID DB09037
Checkpoints PD-1
Signature Type Protein
Signature PD-L1
Official Symbol CD274
Mode of action PROT_R_UP
Description for ‘mode of action’：the ‘mode of action’ for signature is composed of three parts: A_B_C. A describes the level at which the corresponding signature changes, it may contain the following values: TRAN(translation), PROT(protein), CE(cell), METH(methylation), AC(acetylation), PHOS(phosphorylation), MU(mutation), SNP(single nucleotide polymorphism), GLYC(glycosylation) and PATH(pathway). B describes the corresponding signature in which cancer immunotherapy condition group has changed, it may contain the following values: R (immunotherapy response group), NR(immunotherapy non-response group), D (Immunotherapy group), ND (No immunotherapy group). C describes the change detail (specific direction) of the corresponding signature, it may contain the following values: UP (High gene/protein expression or increased cellular abundance or enhanced epigenetic modification), DN (Low gene/protein expression or reduced cellular abundance or attenuated epigenetic modifications), LOSS (deletion mutation), GAIN (gain mutation)，Other. For example, the search/browse detail result for CD274 was “PROT_R_UP”, it can be interpreted that the protein level of CD274 was upregulated in immunotherapy response individuals.
Experimental clinical trial phase 2/3
Description This was the case not only for patients with PD-L1 expression on at least 50% of tumor cells but also for the total study population. Furthermore, a significant improvement in PFS was only reached with pembrolizumab in patients with PD-L1 expression on at least 50% of tumor cells.
