conditions that could affect their participation in the study such as:

- Patients with the presence of active or suspected acute or chronic uncontrolled
infection or with a history of immunodeficiency, including a positive HIV test
result (ELISA and Western blot). An HIV test will not be required; however,
previous medical history will be reviewed.

- Non-malignant medical illnesses that are uncontrolled or whose control may be
jeopardized by the treatment with this study treatment.

- Life-threatening autoimmune and ischemic disorders.

- Patients with the presence of active or suspected acute or chronic uncontrolled
infection

8. Inadequate end organ function as defined by:

12. Patients with symptomatic cholelithiasis

13. Patients with abnormal coagulation (PT and PTT elevated by 30% above normal limits).

14. Patients on continuous anticoagulation therapy. Patients who were on anticoagulant
therapy must complete a washout period of at least 10 days and have confirmed normal
coagulation parameters before study inclusion (patients receiving aspirin once a day
are allowed to be enrolled).

15. Patients who are hypothyroid and not on adequate replacement therapy

16. Patients who have undergone major surgery/surgical therapy for any cause within 1
month. Patients should have recovered from the surgery and be in good clinical
condition before entering the study.

17. Patients who have a history of a primary malignancy (or "another" primary malignancy

exception of locally excised non-melanoma skin cancer, carcinoma in situ of uterine
cervix, and excised mucosal gastric cancer or mucosal colon cancer.

18. Patients with a history of non-compliance to medical regimens or who are considered
potentially unreliable or will be unable to complete the entire study.

19. Clinically significant abnormal laboratory values considered by the investigator or
the medical monitor of the sponsor to be clinically significant or which could have
affected the interpretation of the study results.

cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository
