RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill cancer cells. Sometimes the transplanted cells can be rejected by the body's tissues. Mycophenolate mofetil, tacrolimus, and donor white blood cells may prevent this from happening.
PURPOSE: Phase II trial to study the effectiveness of chemotherapy followed by peripheral stem cell transplantation in treating patients who have metastatic or recurrent kidney cancer.
- Determine the feasibility of submyeloablative HLA-identical allogeneic peripheral blood stem cell transplantation in patients with metastatic or recurrent renal cell carcinoma.
- Determine the toxicity of this regimen, in terms of incidence and severity of graft rejection, acute graft-vs-host disease (GVHD), chronic GVHD, adverse effects from the preparative regimen and thalidomide, and infection and bleeding, in these patients.
- Determine the efficacy of this regimen, in terms of objective partial and complete response rates, in these patients.
- Determine the engraftment rates and extent of chimerism in patients treated with this regimen.
- Determine the overall survival and time to treatment failure rate in patients treated with this regimen.
- Determine the impact of thalidomide on the treatment of chronic GVHD in patients treated with this regimen.
OUTLINE: Patients are stratified according to risk (low vs high).
Patients receive fludarabine IV over 30 minutes once daily on days -4 to -2 followed by total body irradiation on day -1. Patients receive tacrolimus IV over 24 hours or orally daily on days -3 to 35 and oral mycophenolate mofetil twice daily on days -3 to 28 as graft-vs-host disease (GVHD) prophylaxis. Patients undergo allogeneic peripheral blood stem cell transplantation over 1-2 hours on day 0.
Patients maintaining a mixed chimerism with no evidence of grade III or IV GVHD receive donor lymphocyte infusions (DLI) on days 60, 90, and 120. Patients may receive additional DLI as needed. Patients with limited chronic GVHD receive oral thalidomide daily beginning after day 80 and continuing for 1 year or until disease progression or resolution of chronic GVHD.
Patients are followed at 1, 3, 6, and 12 months and then every 6 months thereafter.
PROJECTED ACCRUAL: A maximum of 20-40 patients (10-20 per stratum) will be accrued for this study.

The objective of the study was to investigate the pharmacokinetic drug-drug interactions between tacrolimus (TAC) and mycophenolate mofetil (MMF) in healthy Korean male volunteers. Seventeen volunteer...

A 12-KDa tacrolimus binding protein that is found associated with and may modulate the function of calcium release channels. It is a peptidyl-prolyl cis/trans isomerase which is inhibited by both tacrolimus (commonly called FK506) and SIROLIMUS.
A family of immunophilin proteins that bind to the immunosuppressive drugs TACROLIMUS (also known as FK506) and SIROLIMUS. EC 5.2.1.-
A macrolide isolated from the culture broth of a strain of Streptomyces tsukubaensis that has strong immunosuppressive activity in vivo and prevents the activation of T-lymphocytes in response to antigenic or mitogenic stimulation in vitro.
A serine threonine kinase that controls a wide range of growth-related cellular processes. The protein is referred to as the target of RAPAMYCIN due to the discovery that TACROLIMUS (commonly known as rapamycin) forms an inhibitory complex with TACROLIMUS BINDING PROTEIN 1A that blocks the action of its enzymatic activity.
An enzyme of the transferase class that catalyzes the conversion of sedoheptulose 7-phosphate and D-glyceraldehyde 3-phosphate to D-ribose 5-phosphate and D-xylulose 5-phosphate in the PENTOSE PHOSPHATE PATHWAY. (Dorland, 27th ed) EC 188.8.131.52.
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
