Amgen Incorporated |
Indication |
Vectibix is an epidermal growth factor receptor antagonist indicated as a single agent for the treatment of metastatic colorectal carcinoma with disease progression on or following fluoropyrimidine, oxaliplatin, and irinotecan chemotherapy regimens. Approval is based on progression-free survival; no data demonstrate an improvement in disease-related symptoms or increased survival with Vectibix. |
Cell Substrate |
Genetically engineered mammalian (Chinese Hamster Ovary) cells. |
Manufacturing platform |
Panitumumab is produced from Chinese Hamster Ovary (CHO) cells and purified by a series of chromatography steps, viral inactivation step, viral filtration step and ultrafiltration/diafiltration steps. The expression plasmid containing the genes for the heavy and light chains was transfected into CHO cells. Following cloning and sub-cloning steps, one clone producing panitumumab at high levels was selected as lead cell line. A two-tiered cell banking system of Master Cell bank (MCB) and Working Cell Bank (WCB) has been developed and maintained in accordance to cGMP and ICH guidelines. |
Dose in vial/final container |
Single-use vials (20 mg/mL): 100 mg/5 mL, 200 mg/10 mL, 400 mg/20 mL. |
Dose to patient |
6 mg/kg every 14 days as an intravenous infusion over 60 minutes (≤ 1000 mg) or 90 minutes (> 1000 mg) |
