A Study of EZN-2208 Administered With or Without Cetuximab in Patients With Metastatic Colorectal Carcinoma

Not Recruiting

Trial ID: NCT00931840


This is a Phase 2, multicenter, multiple-arm, open-label study to evaluate the efficacy, safety, and tolerability of EZN-2208. EZN-2208 will be administered as a single agent in patients with K-RAS mutations in the tumors. Patients with wild type K-RAS in tumors will be randomized to EZN-2208 + cetuximab or to standard of care (Camptosar® + cetuximab), patients must have failed regimens containing irinotecan (Camptosar®, CPT-11), oxaliplatin (Eloxatin®), and fluoropyrimidine. After discontinuation of study treatment, patients will receive care as considered appropriate by the investigator. Patients will continue to be followed for disease progression, subsequent anticancer therapy, and survival.

2. Patients must agree to genetic testing of the original or metastatic CRC tumor biopsy tissue for K-RAS mutational status.
3. Disease progression
4. Previous therapy with irinotecan, oxaliplatin, and fluoropyrimidine either alone or in any combination(s). Patients must have radiographically documented progressive disease while receiving, or within 3 months of receiving, these agents alone or in combination.

8. ECOG performance status of 0 or 1
9. Adequate bone marrow, renal, and hepatic function

Exclusion Criteria:

* Patients meeting any of the following exclusion criteria will not be eligible for enrollment.

1. Known chronic infectious disease
2. Major surgery within 3 weeks before study start
3. Known or suspected brain metastases requiring intervention with steroids and/or radiation therapy.
4. Prior chemotherapy, immunotherapy, non-investigational agent, or other therapy used to treat the cancer within 3 weeks before the scheduled administration of EZN-2208
5. History of other primary cancer within 5 years of enrollment, unless

1. Curatively resected non-melanomatous skin cancer, or
2. Curatively resected cervical cancer
6. Lack of recovery to Grade 1 from any reversible side effects related to the administration of an investigational agent, or other prior treatments for the cancer
7. Any condition such as uncontrollable diabetes, uncontrollable hypertension, or active infection.
8. Current participation in another clinical study with an investigational agent and/or use of an investigational drug (not including investigational use of an approved drug) in the 30 days before the first administration of EZN-2208
