Study summary

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.

Read the detailed 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.

What researchers measure

Primary outcomes

  1. Safety measured by major hemorrhage (NCI CTCAE v3.0 grade 3 or greater), during and up to 30 days after completion of study drug administration or, if treatment is ongoing, by 8 months after study enrollment (Stage I) or randomization (Stage II)

    Time frame: 30 days after study completion

Secondary outcomes

  1. Safety measured by adverse events

    Time frame: 30 days after study completion

  2. Efficacy measured by new metastasis-free survival by 8 months

    Time frame: 8 months

  3. Survival by 8 months

    Time frame: 8 months

  4. Arterial or venous thrombosis

    Time frame: 8 months

  5. Tumor response rate, as assessed by RECIST criteria

    Time frame: 30 days after study completion
