Brief Summary:

This study will be conducted in subjects with refractory colorectal carcinoma with unresectable liver metastases. The purposes of the study are:

  • to evaluate the safety and any harmful effects of an intravenous injection of Ad.hIFN-β;
  • help determine whether the virus carrying the interferon-beta gene will enter the bloodstream and liver tumor cells and cause the cancer cells to die.

Condition or disease Intervention/treatment Phase
Colorectal Carcinoma Metastases Drug: Ad.hIFN-β (BG00001, IDEC-201) Phase 1 Phase 2

Detailed Description:
This trial is a clinical research study of Ad.hIFN-β, an investigational, replication-defective, recombinant adenovirus containing the human interferon beta gene, for people that have refractory colorectal carcinoma with liver metastases. Scientists have been exploring a variety of approaches to develop medications to treat patients with refractory colorectal carcinoma with liver metastases; a disease for which current treatment provides only limited relief, so there is a need for new medications.

Primary Outcome Measures :
  1. - Evaluate the safety of a single IV administration of Ad.hIFN-β.

Secondary Outcome Measures :
  1. Evaluate the MTD or maximum feasible dose (MFD) of Ad.hIFN-β.
  2. Evaluate IFN-β and Ad.hIFN-β vector serum concentrations.
  3. Evaluate immunogenicity of Ad.hIFN-β by measuring human anti adenovirus and human anti-IFN-β antibody formation.
  4. Explore preliminary clinical activity.

  • Unwillingness or inability to comply with procedures required in this protocol.
  • Known infection with HIV, hepatitis B, or hepatitis C.
  • Serious nonmalignant disease (e.g., hydronephrosis, liver failure, or other conditions) that could compromise protocol objectives in the opinion of the investigator and/or the sponsor.
  • Clinically significant bleeding event within the last 3 months, unrelated to trauma.
  • More than 50% of liver replaced by tumor (estimated by the PI from CT scan within 14 days of Day 1).
