Panitumumab | Vectibix | ABX-EGF | EGFR Antibody 60 | Vectibix (panitumumab) is a monoclonal antibody directed against EGFR, which inhibits cell proliferation and induces apoptosis (PMID: 18998757). Vectibix (panitumumab) is FDA approved for metastatic colorectal cancer patients with wild-type KRAS and NRAS (FDA.gov). |
Trametinib | Mekinist | GSK1120212 | MEK inhibitor (Pan) 26 MEK1 Inhibitor 26 MEK2 Inhibitor 24 | Mekinist (trametinib) inhibits MEK 1 and 2, which potentially leads to reduced tumor cell proliferation (PMID: 27956260). Mekinist (trametinib) is FDA approved for melanoma patients harboring BRAF V600E or BRAF V600K mutations, and in combination with Tafinlar (dabrafenib) for BRAF V600E/K-mutant melanoma, BRAF V600E- mutant non-small cell lung cancer, BRAF V600E-mutant anaplastic thyroid cancer, for adult and pediatric patients of 6 years or older with unresectable or metastatic solid tumors harboring BRAF V600E, and for pediatric patients of 1 year or older with low-grade glioma harboring BRAF V600E (FDA.gov). |

MAP2K1 K57T | colorectal cancer | sensitive | Panitumumab + Trametinib | Case Reports/Case Series | Actionable | In a clinical case study, a combination of Vectibix (panitumumab) and Mekinist (trametinib) caused tumor regression in a patient’s colorectal cancer metastases harboring MAP2K1 K57T after being identified pre-clinically as a combination likely to inhibit MAP2K1 K57T expressing colorectal cancer (PMID: 26644315). | 26644315 |
BRAF V600E | colorectal cancer | no benefit | Panitumumab + Trametinib | Phase I | Actionable | In a Phase I trial, combination therapy consisting of Vectibix (panitumumab) and Mekinist (trametinib) resulted in an overall response rate of 0% (0/31), stable disease in 55% (17/31), and a median progression-free survival of 2.6 months in patients with BRAF V600E colorectal cancer (PMID: 29431699; NCT01750918). | 29431699 |
MAP2K1 K57N | colorectal cancer | sensitive | Panitumumab + Trametinib | Preclinical | Actionable | In a preclinical study, Vectibix (panitumumab) and Mekinist (trametinib) inhibited colorectal cancer cell lines expressing MAP2K1 K57N in culture (PMID: 26644315). | 26644315 |
