A Phase 2 Study of EZN-2208 (PEG-SN38) Administered With or Without Cetuximab in Patients With Metastatic Colorectal Carcinoma (mCRC)

EZN-2208 will be administered by i.v. infusion weekly for 3 weeks in 4-week cycles. The
cetuximab infusion will be administered before the EZN-2208 (Arm B) or irinotecan (Arm C)
infusion. Study treatment will be continued until evidence of disease progression,
unacceptable toxicity, or withdrawal of the patient's consent for participation in the

K-RAS mutated arm and approximately 120 patients in the wild-type K-RAS arm.

1. Histologically confirmed CRC adenocarcinoma that is metastatic or locally
recurrent CRC that is nonresectable

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.

used to treat the cancer within 3 weeks before the scheduled administration of

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

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
