Title: Head to Head Comparison of Myfortic vs. Cellcept in the Treatment of Kidney Transplant Recipients Using Our Current Center Standardized Concomitant Immunosuppressive Protocol
Brief Summary: The comparison the incidence of G.I. toxicity between Myfortic® vs. Cellcept® in 150 sequential patients, in which 75 will be randomized to Cellcept® and 75 to Myfortic® in first and second living or deceased donor renal transplant recipients.


Options:
A: Inclusion Criteria:

* Patients who provide written informed consent.

Exclusion Criteria:

* PRA \> 20% within 6 months prior to enrollment
* Cold ischemia time \> 30 hours
* Previous treatment with daclizumab
* History of malignancy (except localized skin cancer)

2. Age 18-75 years.
3. Weight \> 40 kg.
4. Primary or secondary renal allograft: living or deceased donor.
5. Negative standard crossmatch for T cells.
6. Women of childbearing potential will be required to have a negative qualitative serum pregnancy test and agree to use an adequate method of contraception for the study duration.
7. Males and females are to be studied equivalently as they become available for transplantation using these criteria.

Exclusion Criteria:

1. Patient has previously received or is receiving an organ transplant other than a kidney.
2. Patient is receiving an ABO incompatible donor kidney.
3. Recipient or donor is seropositive for human immunodeficiency (HIV), Hepatitis C viruses, or Hepatitis B virus antigenemia.

5. Patients with significant liver disease, defined as having during the past 28 days continuously elevated AST (SGOT) and/or ALT (SGPT) levels greater than 3 times the upper value of the normal range of this center.
6. Patient has uncontrolled concomitant infections and/or severe diarrhea, vomiting, active upper gastro-intestinal tract malabsorption or an active peptic ulcer or any other unstable medical condition that could interfere with study objectives.
7. Patient is currently participating in another clinical trial of an investigational drug in the 30 days prior to transplant.
8. Patient will be receiving any immunosuppressive agent other than those prescribed in the study.
9. Patient is unable to take medications orally or via nasogastric tube by the morning of the second day following completion of the transplant procedure (i.e., skin closure) (Group I only).
10. Patient is receiving or may require warfarin, fluvastatin, or herbal supplements during the study.
11. Concurrent use of astemizole, pimozide, cisapride, terfenadine, or ketoconazole.
12. Patient has a known hypersensitivity to tacrolimus, thymoglobulin, IL-2 receptor inhibitor monoclonal antibodies, sirolimus, MMF, Myfortic®, or corticosteroids.
13. Patient is pregnant or lactating.
14.

15. Patient is unlikely to comply with the visits scheduled in the protocol.
16. Patient has any form of substance abuse, psychiatric disorder or a condition that, in the opinion of the investigator, may invalidate communication with the investigator.

If tacrolimus cannot be instituted for longer than 5 days postoperatively.
C: Inclusion criteria:

* Male or female renal recipients 18-70 years of age undergoing kidney transplantation, either primary or re-transplant;
* Recipient of a cadaveric, deceased donor (including expanded criteria donor organs and deceased donor organs after cardiac death), living unrelated or non-HLA identical living related donor kidney;
* Graft must be functional (producing greater than or equal to 100 ml of urine within 24 hours after transplantation) at time of randomization.

Exclusion criteria:

* Donor organ with a cold ischemic time \> 30 hours;
* Males or females who produce less than 100 ml of urine in the first 24 hours post-transplantation;
* Males or females who are recipients of ABO incompatible transplants, or T cell, or B cell crossmatch positive transplant;
* Males or females with severe total hypercholesterolemia or total hypertriglyceridemia (Patients on lipid lowering treatment with controlled hyperlipidemia are acceptable);
* Males or females who have any surgical or any medical condition, such as severe diarrhea, active peptic ulcer disease, or uncontrolled diabetes mellitus, which in the opinion of the investigator, might alter the absorption, distribution, metabolism and/or excretion of study medication.

Other protocol related inclusion/exclusion criteria may apply.
D: Inclusion Criteria:
