Inclusion Criteria

INCLUSION CRITERIA:

1. Age 18 - 70 years

2. Histologically-confirmed, advanced/metastatic solid tumor that is relapsed and/or
refractory to standard therapy (progressive disease despite therapy).

3. Cancer is not surgically resectable for cure.

4. At least one measurable tumor mass by PETCT (i.e. PET-positive lesion that can
reliable be assessed for SUV (standard update value) peak/SUV max, typically
featuring longest diameter greater than or equal to 1 cm) and that can be injected by
direct visualization/palpitation or by imaging-guidance (ultrasound)

8. Total bilirubin less than or equal to ULN (Upper Limit of Normal)

9. AST (Aspartate transaminase), ALT (Alanine aminotransferase) less than or equal to
3.0 × ULN

10. Serum creatinine less than or equal to 1.5 x ULN

11. INR (International Normalized Ratio) less than or equal to 1.5 x ULN

12. Hematologic parameters: Patients can be transfused to meet these entry criteria:

1. Hemoglobin greater than or equal to 10 g/dL

2. Leucocytes greater than or equal to 2300/mL

3. platelet count greater than or equal to 75,000 plts/mm

13. Willing to participate as demonstrated by signed informed consent form.

EXCLUSION CRITERIA:

1. Known brain metastases or glioma. Central Nervous System malignancy, including
carcinomatosis meningitis.

2. Tumor in the immediate pericardial vicinity

3. Use of high dose systemic corticosteroids or other immune suppressive medication
within 3 weeks of first treatment.

6. Use of anti-viral medication. [Patients who discontinue such medications within 7
days prior to first treatment may be eligible for this study.]

7. Recent thromboembolic event

8. Clinically significant active infection or uncontrolled medical condition considered
high risk for investigational new drug treatment (e.g. pulmonary, neurological,
cardiovascular, metabolic such as type 2 diabetes, clinically significant and/or
rapidly accumulating ascites, peri-cardial and/or pleural effusions)

9. Severe or unstable cardiac disease.

10. Current, active, progressing CNS (Central nervous system) malignancy, including
carcinomatosis meningitis (definitively surgically resected or irradiated metastases
allowed)

11. Pulse oximetry O2 (oxygen) criterion <90% at rest on room air

12. Vaccination with a live virus (i.e. measles, mumps, rubella, etc) < 30 days prior to
first treatment
