Inclusion Criteria:

- Adequate hepatic, renal, and hematologic function;

- Life expectancy > 3 months;

- Part 1 and 2: The subject has histopathologically or cytologically documented,
measurable, unresectable, locally advanced primary or recurrent, metastatic solid
tumor, locally advanced primary or recurrent, metastatic pancreatic adenocarcinoma
and must have received at least one prior treatment regimen containing gemcitabine or
5-FU, and locally advanced primary or recurrent, metastatic colon adenocarcinoma.

Exclusion Criteria:

- Parts 1 and 2:

1. Malignant melanoma, Merkel cell cancer, small cell lung cancer, lymphoepithelial
carcinoma, malignant mesothelioma, GIST, Hodgkin and NHL, thymoma,
neuroendocrine, neuronal tumors, and sarcomas. This list of excluded tumors may
be modified as additional research findings become available on target antigen
expression;

2. The subject has received anti-cancer chemotherapy, hormonal therapy,
radiotherapy, immunotherapy, or investigational agents within 4 weeks (6 weeks
for mitomycin C and nitrosoureas) prior to the first dose of CEP-37250/KHK2804;

3. The subject has received monoclonal antibodies of any type or for any form of
disease within 4 weeks of the first dose of CEP-37250/KHK2804;

4. Major surgery within 4 weeks prior to the first dose;

5. Known symptomatic brain metastases (screening magnetic resonance imaging (MRI)
of the brain is only required when there is clinical suspicion of central
nervous system [CNS] involvement or past history of treated brain metastasis).
Subjects with treated brain metastasis (radiotherapy and/or surgery) will be
eligible if they:

- Have completed treatment for their brain metastasis > 4 weeks prior to scheduled
study treatment start date;

- Are neurologically stable;

- Are on corticosteroids in doses no greater than physiological replacement (e.g.,
dexamethasone < 1.5 mg/day); and

- Have a screening MRI scan of the brain that specifically verifies no evidence of CNS
hemorrhage and no active gadolinium enhancing lesions;

- Subjects with primary brain/CNS malignancy (e.g., gliomas, lymphomas) are excluded.

- Hypersensitivity reaction to monoclonal antibodies, other therapeutic proteins,
or allergy to any component of the CEP-37250/KHK2804 finished drug and the
reaction could not be controlled or prevented on subsequent infusion with
standard therapies such as antihistamines, 5-HT3 antagonists, or
corticosteroids.
