---|---|---|---|---|---|---|---|
PBRM1 loss | melanoma | sensitive | unspecified CTLA4 antibody + unspecified PD-1 antibody | Preclinical - Cell line xenograft | Actionable | In a preclinical study, knocking-out PBRM1 in melanoma cells sensitized cells to immune therapy consisted of anti-CTLA4 and anti-PD-1 antibodies in culture and in cell line xenograft models, potentially due to increased sensitivity to T cell-mediated cytotoxicity and a favorable tumor microenvironment (PMID: 29301958). | 29301958 |
PBRM1 loss | lung cancer | sensitive | PRT2527 | Preclinical - Cell line xenograft | Actionable | In a preclinical study, PRT2527 inhibited tumor growth in a lung cancer cell line xenograft model with loss of PBRM1 (PMID: 38371625). | 38371625 |
PBRM1 loss | lung cancer | sensitive | PRT1419 + Sunitinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, the combination of PRT1419 and Sutent (sunitinib) inhibited tumor growth and tumor re-growth in a lung cancer cell line xenograft model with loss of PBRM1 (PMID: 38371625). | 38371625 |
