Brief Summary:
This study is being done to find out whether patients who receive a kidney transplant can benefit from taking the medication paricalcitol (trade name Zemplar®) as compared to kidney transplant recipients not taking this medication. The main possible benefits being studied are:
* Lower risk for overactive parathyroid glands after kidney transplantation.
* Lower risk of low bone density in the spine and hip after kidney transplantation. By dividing patients in the study into a group receiving Zemplar® and a group not receiving Zemplar®, it will be possible to understand the good and bad effects of Zemplar® during the first year after a kidney transplant.
* Lower risk for overactive parathyroid glands after kidney transplantation.
* Lower risk of low bone density in the spine and hip after kidney transplantation. By dividing patients in the study into a group receiving Zemplar® and a group not receiving Zemplar®, it will be possible to understand the good and bad effects of Zemplar® during the first year after a kidney transplant.
Detailed Description:
The most significant challenge in kidney transplantation at present is that of reducing the risk of long-term complications. This includes hyperparathyroidism, a common post kidney transplant complication that contributes to loss of bone density and fracture risk and necessitates surgical intervention in approximately 5% of kidney transplant patients.
In order to take part in the study you will already have been accepted for kidney transplantation from a living donor or from a deceased donor at Mayo Clinic in Rochester, Minnesota. After you have agreed to take part in the study you will be put in one of two groups by chance (as in the flip of a coin):
Group 1 (Standard Treatment or "Control"): Patients in this group will receive a combination of four anti-rejection medications that have been used at Mayo Clinic Rochester for many kidney transplant patients and does not include any research study medicines. These medications will include:
1. Alemtuzumab (Campath®) - this medicine will be given intravenously (IV) on the day of the transplant during surgery.
2. Methylprednisolone (Solumedrol®) - this medicine, which is part of a family of medicines often referred to as corticosteroids, will be given intravenously on the day of the transplant during surgery. This will be the only planned dose of corticosteroid medicine you will receive although this medicine and a tablet form called Prednisone may be given at a later time if you have an episode of transplant rejection.
3. Mycophenolate Mofetil (Cellcept®) - this medicine will be given by mouth twice daily beginning the evening before the transplant (for living donor transplants) or the day of the transplant (for deceased donor transplants). It will be continued for as long as you have your transplant unless there is a medical reason to stop it.
4. Tacrolimus (Prograf®) - this medicine will be given by mouth once daily beginning on the fourth day after the transplant. It will continue for as long as you have your transplant unless there is a medical reason to stop it. The dose will be adjusted based on a blood test that will be done between twice a week and once a month for as long as you take the medicine.
Group 2 (Zemplar® + Standard Treatment): Patients in this group will receive the same combination of anti-rejection medications as the patients in Group 1 (a-d above) plus Zemplar®, which is the medicine being studied, will also be started on the day of the transplant. Zemplar® will be given as a capsule containing 1 microgram of Zemplar® once daily beginning the day after the transplant. It will be continued at the same dose for the first two weeks then, depending on the results of blood and urine testing, will be increased to 2 micrograms daily. The dose will remain at 2 micrograms daily until the end of the study unless there is a medical reason to reduce or stop it or unless the study is stopped early.
Both groups of patients will be treated by the same team of doctors, nurses and nurse coordinators that care for all kidney transplant patients at Mayo Clinic. The procedures and treatments for your transplant will be the same as those recommended at Mayo Clinic for all patients receiving a kidney transplant. These include the surgical operation to carry out the transplant; the need to take anti-rejection medicines by mouth for the rest of your life; the need to have blood and urine testing at regular intervals for the rest of your life to monitor the progress of your transplant; and the recommendation to have a biopsy of your transplant carried out on three occasion during the first two years after the transplant surgery. These procedures and their potential complications will be described to you in detail by your transplant physician, transplant surgeon, and transplant coordinator. The study will not require extra hospital or outpatient visits compared to the usual care for all kidney transplant patients at Mayo Clinic Rochester.
