Brief Summary

Despite the advances in the medical treatment of unresectable liver metastases from colorectal cancer there is currently no curative treatment option available for these patients. Decitabine is a cytidine analog with proven anti-neoplastic activity in patients with acute myeloid leukemia and myelodysplastic syndromes. Decitabine causes demethylation of the DNA strands of replicating cells. Hereby decitabine treatment demethylates the promoter regions of tumor suppressor- and cancer testis antigen encoding genes leading to expression of these genes by the cancer cells. The hepatic arterial route for administration of cytotoxic drugs has been widely explored in treatment of colorectal cancer liver metastases because these metastases depend for their blood flow from this artery (as opposed to the normal liver tissue that is mainly dependent from the portal vein). By investigating the administration of decitabine by hepatic arterial infusion the investigators intend to explore the potential advantage of minimizing the systemic exposure (and toxicity) and maximizing the concentration of decitabine within the liver metastasis. The primary objective of this phase I will be to establish the recommended dose for decitabine by HAI for further use in phase II trials. The most important secondary objective will be to document the effect of decitabine by HAI on the expression of cancer testis antigens by the colorectal cancer cells, serving as a reference for potential further exploration of decitabine by HAI in combination with cancer immunotherapy

Detailed Description

This clinical trial will recruit eligible patients diagnosed with unresectable liver-predominant colorectal cancer metastases who have experience progression of their disease following standard of care treatment.

Unless patients already dispose of a hepatic arterial catheter, they will undergo placement of a permanent hepatic artery catheter (by laparoscopic surgery). During this surgical procedure a biopsy will be made of the colorectal cancer liver metastasis.

Decitabine will be administered as a daily 1-hour IV infusion on 5 consecutive days, every 4weeks.

Two weeks after the first day of administration of decitabine, a CT-guided biopsy a liver metastasis will be performed in order to obtain tumor tissue for histopathological analysis and DNA/RNA extraction for the purposes of methylation specific Polymerase Chain Reaction (PCR) and reverse transcriptase PCR for assessment of demethylation and expression of cancer-testis antigen encoding genes.

Blood samples for collection of "cell-free DNA" and White Blood Cell (WBC ) for the purpose of DNA/RNA extraction and analysis by methylation specific PCR and reverse transcriptase PCR for assessment of demethylation and expression of cancer-testis antigen encoding genes will be obtained weekly after decitabine treatment.

The dose of decitabine will be escalated in subsequent patient cohorts enrolled to this phase I trial (see rules for dose escalation).

Study treatment will be continued until unacceptable toxicity, progressive disease or patient refusal.
