Phase 1/2 Study to Assess the Safety and Efficacy of Vaccinations With Allogeneic Dendritic Cells: Autologous Tumor-Derived Cells Subjected to Electrofusion in Patients With AJCC Stage IV Renal Cell Carcinoma

Inclusion Criteria:

- The patient must be greater than or equal to 18 years of age.

- The patient must be diagnosed with AJCC Stage IV (primary or relapsed) Renal Cell
Carcinoma.

- The patient must have a Screening Eastern Cooperative Oncology Group (ECOG) Clinical
Performance Status of 0-1.

- The patient must have accessible tumor (minimum of 2.5 cm in diameter in aggregate
and accessible as defined in the clinical protocol) for vaccine production.

- The patient must have measurable tumor lesions (using Response Evaluation Criteria in
Solid Tumors [RECIST]) following resection of tumor lesion(s) used for vaccine
production. If the patient has received previous radiation or intra-tumoral
investigational treatments, the measurable disease must be outside the previous
radiation port or treatment area unless there is documented tumor progression
following the completion of therapy.

- The patient must have adequate hematologic, hepatic, and renal function parameters at
Screening: White blood cell (WBC) count greater than or equal to 3,000 cells/mm3;
Platelet count greater than or equal to 100,000 platelets /mm3; Creatinine (serum)
less than 2.0 mg/dL; Total bilirubin less than 2.0 mg/dL; Serum glutamic pyruvate
transaminase (SGPT)/alanine aminotransferase (ALT) less than 2.0 x Upper limits of
normal; Serum glutamic oxaloacetic transaminase (SGOT)/ aspartate aminotransferase
(AST) less than 2.0 x Upper limits of normal

- The patient must be serologically negative for human immunodeficiency virus (HIV)-1,
HIV-2, and human T lymphotropic virus (HTLV)-1.

- Female patients of childbearing potential must have negative pregnancy tests, refrain
from nursing and must agree to use appropriate contraception for the duration of the
trial.

- The patient must have signed and dated written informed consent prior to any study
procedures. The consent process must be documented in the patient's medical record.

Exclusion Criteria:

- The patient has received prior chemotherapy for the treatment of RCC.

- The patient has received more than 2 prior regimens for treatment of RCC and the most
recent is within 2 weeks of the first screening procedure.

- The patient has received radiation therapy within 2 weeks of the first screening
procedure.

- The patient has a clinically significant autoimmune disorder.

- The patient has an active infection at the time of the first screening procedure
requiring parenteral antibiotics.

- The patient has clinically significant hematologic, cardiac, renal, or hepatic
disease or any other underlying condition that would contraindicate study therapy or
confuse interpretation of study results.

- The patient has a history of more than one brain metastasis. Patients with a history
of a single brain metastasis must have completed definitive treatment for this
metastasis not less than 12 weeks prior to the time of first screening procedure and
have remained clinically stable during this interval.

- The patient has a previous unrelated malignancy or second malignancy within 5 years
prior to the first screening procedure, except for non-melanoma skin cancer and in
situ carcinomas.

- The patient is receiving chronic immunosuppressive and/or oral steroid treatment.

- The patient has any other reason in the Investigator's opinion that would make
protocol compliance unmanageable or may compromise the patient's ability to give
informed consent.

- The patient has been treated with a non-oncologic investigational drug, biologic or
medical device within 30 days of the first screening procedure.
