PD-0325901 | PD0325901|PD 0325901|PD-901|Mirdametinib | MEK inhibitor (Pan) 26 MEK1 Inhibitor 26 MEK2 Inhibitor 24 | PD-0325901, a derivative of CI-1040, is a pan-MEK inhibitor, which inhibits activation of MAPK/ERK resulting in decreased tumor cell proliferation (PMID: 18952427, PMID: 32147669). | |
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). |

NRAS mutant | melanoma | sensitive | Palbociclib + PD-0325901 | Preclinical - Cell line xenograft | Actionable | In a preclinical study, the combination treatment of PD-0325901 and Ibrance (palbociclib) resulted in tumor regression in 33% (2/6) of melanoma xenograft models harboring an NRAS mutation (PMID: 27488531). | 27488531 |
PIK3CA E545G | colorectal adenocarcinoma | sensitive | Palbociclib + PD-0325901 | Preclinical - Cell culture | Actionable | In a preclinical study, the combination of Ibrance (palbociclib) and PD-0325901 synergistically inhibited growth of a colorectal adenocarcinoma cell line harboring PIK3CA E545G in culture (PMID: 37326340). | 37326340 |
BRAF V600E | melanoma | sensitive | Palbociclib + PD-0325901 | Preclinical - Cell line xenograft | Actionable | In a preclinical study, the combination treatment of PD-0325901 and Ibrance (palbociclib) resulted in significant tumor regression in melanoma cell line xenograft models harboring BRAF V600E and demonstrated a 56% (5/9) complete response rate (PMID: 27488531). | 27488531 |
BRAF V600E | colorectal carcinoma | no benefit | Palbociclib + PD-0325901 | Preclinical - Cell culture | Actionable | In a preclinical study, the combination of Ibrance (palbociclib) and PD-0325901 demonstrated antagonism in a colorectal carcinoma cell line harboring BRAF V600E in culture (PMID: 37326340). | 37326340 |
