The European Commission approved a new use of Vectibix (panitumumab) as first-line treatment in combination with FOLFIRI chemotherapy for the treatment of adult patients with wild-type RAS metastatic colorectal cancer.
The new indication is based upon studies that evaluated Vectibix plus FOLFIRI in the first-line setting. Vectibix is now approved in the European Union for the treatment of adult patients with WT RAS mCRC: in first-line in combination with FOLFOX or FOLFIRI; in second-line in combination with FOLFIRI for patients who have received first-line fluoropyrimidine-based chemotherapy (excluding irinotecan); and as monotherapy after failure of fluoropyrimidine-, oxaliplatin-, and irinotecan-containing chemotherapy regimens.
In the U.S., Vectibix is indicated for the treatment of patients with wild-type KRAS (exon 2 in codons 12 or 13) metastatic colorectal cancer as determined by an FDA-approved test for this use: as first-line therapy in combination with FOLFOX; or as a monotherapy following disease progression after prior treatment with fluoropyrimidine-, oxaliplatin-, and irinotecan-containing chemotherapy.
