PTEN loss RB1 loss | triple-receptor negative breast cancer | no benefit | Palbociclib + Pictilisib | Preclinical | Actionable | In a preclinical study, the combination of Ibrance (palbociclib) and Pictilisib (GDC-0941) did not improve growth inhibition compared to single drug treatment in triple-receptor negative breast cancer cell lines harboring PTEN and RB1 loss in culture (PMID: 27020857). | 27020857 | |
PTEN loss RB1 loss | triple-receptor negative breast cancer | resistant | Pictilisib | Preclinical | Actionable | In a preclinical study, a triple-receptor negative breast cancer line harboring PTEN and RB1 loss was resistant to Pictilisib (GDC-0941) induced growth inhibition in culture (PMID: 27020857). | 27020857 | |
