Palbociclib | Ibrance | PD0332991|PD-0332991 | CDK4/6 Inhibitor 14 | Ibrance (palbociclib) is a selective inhibitor of cyclin-dependent kinase 4 (CDK4) and 6 (CDK6) (PMID: 19874578). Ibrance (palbociclib) is approved in combination with an aromatase inhibitor in postmenopausal patients with ER-positive, ERBB2 (HER2)-negative metastatic breast cancer, and in combination with Faslodex (fulvestrant) in patients with ER-positive, ERBB2 (HER2)-negative metastatic breast cancer (FDA.gov). |
Pictilisib | GDC-0941|GDC0941|GDC 0941 | PI3K Inhibitor (Pan) 42 | Pictilisib (GDC-0941) inhibits isoforms of PI3K, which inhibits PI3K/AKT signaling resulting in antitumor activity, including inhibition of tumor growth (PMID: 19584227). |

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 |
PIK3CA mutant | triple-receptor negative breast cancer | sensitive | Palbociclib + Pictilisib | Preclinical | Actionable | In a preclinical study, Ibrance (palbociclib) and Pictilisib (GDC-0941) worked synergistically to inhibit the survival of triple-receptor negative breast cancer cell lines harboring PIK3CA mutations in culture (PMID: 27020857). | 27020857 |
PIK3CA wild-type | 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 PIK3CA wild-type, triple-receptor negative breast cancer cell lines in culture (PMID: 27020857). | 27020857 |
