Transplant rejection occurs when a patient's body does not recognize the new organ and attacks it. Patients who have kidney transplants must take drugs to prevent transplant rejection. Alemtuzumab is a man-made antibody used to treat certain blood disorders. The purpose of this study is to test the safety and effectiveness of using alemtuzumab in combination with two other drugs, sirolimus and tacrolimus, to prevent organ rejection after kidney transplantation. This study will also test whether this combination of medications will allow patients to eventually stop taking antirejection medications entirely.
Study hypothesis: A new strategy of immunosuppression using alemtuzumab, tacrolimus, and sirolimus for human renal transplantation will permit a step-wise withdrawal from immunosuppressive drugs.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Kidney Transplantation Kidney Disease | Drug: Alemtuzumab Drug: Sirolimus Drug: Tacrolimus Procedure: Kidney transplant Drug: Methylprednisolone (or equivalent) Drug: Acetaminophen Drug: Diphenhydramine Drug: Trimethoprim (TMP)/Sulfa (Bactrim, Septra) Drug: Valgancyclovir Drug: Acyclovir Drug: Pentamidine Drug: Clotrimazole Drug: Nystatin | Phase 1 Phase 2 |
Drugs that suppress the immune system, such as sirolimus and tacrolimus, have contributed to increased success of transplantation. However, to prevent organ rejection, transplant recipients need to take immunosuppressive drugs for the rest of their lives, and these drugs make patients more susceptible to infection, endangering their health and survival. Regimens that are less toxic to or can eventually be withdrawn from transplant recipients are needed. Alemtuzumab is a monoclonal antibody that binds to and depletes excess T cells in the bone marrow of leukemia patients. This study will determine the effects of intravenous alemtuzumab and oral sirolimus and tacrolimus after kidney transplantation. The study will also evaluate this regimen's potential to allow eventual discontinuation of components of long-term immunosuppressive therapy.
This study will last up to 4 years. Participants will undergo kidney transplantation on Day 0 and will receive intravenous doses of alemtuzumab, acetaminophen, and diphenhydramine on Days 0, 1, and 2, as well as methylprednisolone on Day 0. After transplant, patients will receive up to 10 days of valganciclovir or acyclovir. Participants will take tacrolimus daily by mouth for at least 60 days after transplant and sirolimus daily by mouth for at least 12 months after transplant. As part of opportunistic infection (OI) prophylaxis, participants will also take sulfamethoxazole-trimethoprim by mouth 3 times a week, valganciclovir or acyclovir for up to 10 days post-transplant, and clotrimazole or nystatin by mouth for at least 3 months post-transplant.
There will be a minimum of 62 study visits spread out over 4 years after transplant. Vital signs measurement, adverse event and OI reporting, medication history, physical exam, and blood collection will occur at selected visits. Sirolimus withdrawal will begin when a participant meets certain study criteria. The withdrawal process will occur over a minimum of 3 months at an approximate rate of 33% of the pre-withdrawal dose per month. Participants eligible for sirolimus withdrawal will undergo several kidney biopsies, including one 2 weeks prior to the start of withdrawal, 6 and 12 months after completion of withdrawal, 1 year after study enrollment, and annually thereafter.
