About

This is a multicenter, two-stage trial with the goal of evaluating up to 100 subjects. This trial will be performed to initiate identification of a safe and effective dose of twice-weekly, subcutaneous rNAPc2 for the second-line treatment of metastatic colorectal carcinoma in combination with contemporary 5-FU-based chemotherapy.

Full description

Cytotoxic chemotherapy combining 5-fluorouracil and leucovorin with irinotecan (FOLFIRI) or oxaliplatin (FOLFOX) or, more recently, treatment with XELOX (Roche) (capecitabine + oxaliplatin) has been the main approach for the treatment of metastatic colorectal carcinoma (mCRC), but with the advent of targeted therapies, biologic treatments are becoming an area of intense interest. Tissue factor (TF) is a transmembrane glycoprotein expressed by upwards of 85% of mCRCs.
