Therapy Name | Fluorouracil + Irinotecan + Leucovorin + Panitumumab |
Synonyms | Panitumumab + FOLFIRI |
Therapy Description | |
Drug Name | Trade Name | Synonyms | Drug Classes | Drug Description |
---|---|---|---|---|
Fluorouracil | Adrucil | 5-FU | Chemotherapy - Antimetabolite 14 | Adrucil (fluorouracil) is an antimetabolite chemotherapeutic agent, which interferes with DNA and RNA synthesis thereby preventing cancer cell growth and is FDA approved for colorectal, breast, stomach, and pancreatic cancer (FDA.gov). |
Irinotecan | Camptosar | CPT-11|Onivyde | TOPO1 inhibitor 10 | Camptosar (irinotecan) inhibits Topoisomerase-I activity, resulting in inhibition of DNA replication, and potentially leading to cell death and is indicated as a component of first-line therapy in combination with 5-fluorouracil and leucovorin for patients with metastatic or recurrent colorectal carcinoma (FDA.gov). |
Leucovorin | Wellcovorin | Calcium folinate|Calcium citrovorum factor|folinic acid | Chemotherapy - Antimetabolite 14 | Wellcovorin (leucovorin) is a metabolite of folate that enhances the efficacy of fluoruracil (PMID: 32490554). |
Panitumumab | Vectibix | ABX-EGF | EGFR Antibody 51 | 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). |

---|---|---|---|---|---|---|---|
NRAS wild-type | colorectal cancer | predicted - sensitive | Fluorouracil + Irinotecan + Leucovorin + Panitumumab | Phase III | Actionable | In a Phase III clinical trial, the combination of Vectibix (panitumumab) and FOLFIRI improved progression-free survival and median overall survival in patients with RAS wild-type colorectal cancer compared to FOLFIRI treatment alone (PMID: 26341920). | 26341920 |
BRAF D594G | colorectal cancer | not predictive | Fluorouracil + Irinotecan + Leucovorin + Panitumumab | Case Reports/Case Series | Actionable | In a clinical study, the combination of Vectibix (panitumumab) with FOLFIRI as a third-line therapy resulted in stable disease with progression-free survival of 2.6 months in a patient with metastatic colorectal cancer harboring BRAF D594G (PMID: 31515458). | 31515458 |
BRAF L597R | colorectal cancer | not predictive | Fluorouracil + Irinotecan + Leucovorin + Panitumumab | Case Reports/Case Series | Actionable | In a clinical study, the combination of Vectibix (panitumumab) with FOLFIRI as a second-line therapy resulted in stable disease with a PFS of 16.5 months in a patient with metastatic colorectal cancer harboring BRAF L597R (PMID: 31515458). | 31515458 |
