About

This is a Phase I/II open-label, dose-escalating study in patients with metastatic colorectal cancer. The objectives of the study are to obtain information on the safety of radiolabeled IDEC-159, as well as its activity in colorectal cancer. Another objective is to determine the maximum tolerated dose (MTD). The study duration is 2 years with visits occuring daily and/or weekly for the first 3 months, and every 6 weeks until the end of the 2 year period.

Inclusion criteria

Sign an Institutional Review Board (IRB)-approved informed consent.
Metastatic colorectal adenocarcinoma that has been pathologically confirmed following failed response or relapse while on or following fluoropyrimidine, irinotecan, and oxaliplatin chemotherapy. (Prior therapy with cetuximab is recommended if the tumors are epidermal growth factor receptor [EGFR] positive.)
Age 18 or above.
Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2.
Recovered to baseline toxicity from any significant toxicity associated with prior surgery, chemotherapy, biological therapy, or investigational drug.
Adequate bone marrow reserve (absolute neutrophil count > 1500 cells/mm3, platelet count > 125,000 cells/mm3, hemoglobin concentration ≥ 10 g/dL).
Radiographically measurable disease (RECIST criteria).
Life expectancy of at least 3 months.
Male and female subjects of reproductive potential must agree to follow accepted birth control methods, as determined by the investigator, during treatment and for 12 months after completion of treatment.

Exclusion criteria

Prior radioimmunotherapy.
Known presence of central nervous system (CNS) metastasis.
Any lesion > 7.5 cm.
Total bilirubin > 2.0 mg/dL.
Total creatinine > 2.0 mg/dL.
AST and ALT > 2.5 times upper limit of normal (ULN), if metastases to the liver > 5 times ULN.
Presence of a second primary malignancy requiring active treatment (except for hormonal therapy).
Serious non-malignant disease or infection that, in the opinion of either the investigator or sponsor, would compromise protocol objectives.
History of external beam radiation therapy to > 25% of active bone marrow.
History of bone marrow or stem cell transplant.
History of granulocyte colony-stimulating factor (G-CSF) or granulocyte macrophage colony stimulating factor (GM-CSF) therapy within 2 weeks before Study Day 1.
History of pegylated G-CSF therapy within 4 weeks before Study Day 1.
History of major surgery, other than diagnostic surgery, within 4 weeks of Study Day 1.
History of receiving investigational product within 4 weeks before Study Day 1 or long term toxicity from a previous investigational therapy.
Known history of HIV or AIDS.
Concurrent systemic corticosteroid therapy or other immunosuppressive agents, unless for the treatment of computed tomography (CT) dye allergy reactions.
Pregnant or lactating female.
