Active clinical trials for "Graft vs Host Disease"

The purpose of this study is to assess the tolerability and safety of two intensity levels of Theralux extracorporeal photochemotherapy in the treatment of subjects with steroid refractory or intolerant GvHD. The current hypothesis is that apoptotic cells re-injected into patients induce an immunomodulation effect alleviating the GvHD symptoms. Using the Theralux procedure, the dose of photodynamic treatment may be modulated to achieve the maximal immunomodulatory effects in the treated patients. The intervention is iterative extracorporeal photochemotherapy of autologous peripheral blood mononuclear cells (PBMC) with a rhodamine-derivative TH9402 (drug) and Theralux (device).

RATIONALE: Giving chemotherapy and total-body irradiation before a donor bone marrow transplant or peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant may stop this from happening. PURPOSE: This randomized phase III trial is studying donor bone marrow that is treated in the laboratory using two different devices to compare how well they work in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.

Alefacept (AMEVIVE®) is an immunosuppressive dimeric fusion protein. It was shown to interfere with lymphocyte activation by specifically binding to the lymphocyte antigen, CD2, and inhibiting LFA-3/CD2 interaction. Alefacept was evaluated in two randomized, double-blind, placebo-controlled studies in adults with chronic (>1 year) plaque psoriasis and a minimum body surface area involvement of 10% who were candidates for or had previously received systemic therapy or phototherapy. The response to alefacept was significantly better in both studies. In both studies, onset of response to alefacept treatment (defined as at least 50% reduction of baseline Psoriasis Area and Severity Index (PASI)) began 60 days after the start of therapy. Graft versus host disease (GVHD) is the most ominous side effect of allogeneic stem cell transplantation (SCT). It causes severe inflammatory process, which is usually located to the skin, gut and liver. Treatment of GVHD consists of various immuno-suppressive and immuno-modulating drugs, including steroids, cyclosporine, tacrolimus, methotrexate etc. These drugs unfortunately can also cause severe immunologic failure that makes the patient prone to infection and malignancy, and other medication-specific side effects. In spite of this effect on the immune system, not all of the patients achieve control of GVHD, which usually rapidly leads to death. Despite the use of innovative immunosuppressive modalities, the prognosis of steroid resistant GVHD is usually poor. It was shown that CD2 depletion of allografts could prevent GVHD. Alefacept was never systemically tried in GVHD but A phase II study of BTI-322, a rat monoclonal IgG2b directed against the CD2 antigen in steroid-refractory acute GVHD showed a total response rate of 55%. We showed that alefacept might have a beneficial effect in controlling steroid resistant aGVHD and chronic GVHD. It was also shown to dramatically change the nature of transfusion associated GVHD.

This study will examine the safety and effectiveness of extracorporeal photopheresis (ECP) for treating chronic graft-versus-host disease (GvHD). GvHD is a common complication of stem cell transplantation using donated stem cells. It occurs when the donor's T-lymphocytes (a type of immune cell) see the patient's cells as foreign and mount an immune response to reject them. The attack can cause skin rash, mouth sores, liver or lung inflammation, lack of appetite, and muscle stiffness. Chronic GvHD can cause serious illness, and even death, from the long-term effects of immune dysfunction and from toxic effects of medications (such as cyclosporine and prednisone) used to treat it. ECP is an experimental treatment designed to stop the lymphocytes from attacking the body. It involves collecting some of the cells that cause GvHD, treating them with a combination of drug and light therapy and returning them to the body. Sixty to 80 percent of patients with chronic GvHD improve with ECP treatment, and some patients can stop treatment with prednisone or cyclosporine, or reduce the drug dosages. Patients with chronic GvHD whose condition has not improved after a minimum 14-day course of cyclosporine and prednisone may be eligible for this study. Patients must be able to travel to the NIH Clinical Center in Bethesda, Maryland, twice a week during the 3-month study period. Upon entering the study, participants will have a baseline evaluation to measure the extent of GvHD. This assessment includes blood tests, eye and dental examinations, skin biopsy for patients with skin involvement, and CT scans and lung function tests to look for possible lung involvement. Biopsies of the lung, liver, mouth, or eye may be requested if needed to confirm GvHD in these tissues. The skin will be photographed before starting ECP treatment and once a month during the treatment period. Following baseline tests, participants will undergo treatment and evaluations as follows: ECP Treatment Patients will have blood drawn to collect lymphocytes causing GvHD. This may be done with a special needle or catheter (tube inserted into a vein) or for patients who need or prefer it with a temporary central venous catheter similar to that used for the stem cell transplantation. Patients will have three 2- to 3-hour treatments a week for the first week and two treatments a week after that for a total of 25 treatments over 3 months. Patients who do not tolerate the treatment...

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Umbilical cord blood transplantation may allow doctors to give higher doses of chemotherapy or radiation therapy and kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of chemotherapy, radiation therapy, and umbilical cord blood transplantation in treating patients with hematologic cancer.

RATIONALE: Bone marrow that has been treated to remove certain white blood cells may reduce the chance of developing graft-versus-host disease following bone marrow transplantation. PURPOSE: Randomized phase II/III trial to compare the effectiveness of treated bone marrow with that of untreated bone marrow in preventing graft-versus-host disease in patients with acute or chronic leukemia who are undergoing bone marrow transplantation.

The purpose of the study is to evaluate the feasibility and safety of transplanting CD34+ selected hematopoietic cells from a haploidentical related donor following a nonmyeloablative regimen of total lymphoid irradiation (TLI) and antithymocyte globulin (ATG).

Etanercept (Enbrel) will be added to standard therapy for acute Graft-versus-Host Disease to see if the effectiveness of standard therapy can be improved. Partial Funding Source- FDA OOPD

RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. Sometimes the transplanted cells can make an immune response against the body's normal tissues. Treatment of the donor bone marrow with the patient's white blood cells and a monoclonal antibody may prevent this from happening. PURPOSE: Phase I trial to study the effectiveness of bone marrow transplantation with specially treated bone marrow in treating patients who have hematologic cancer that has not responded to previous therapy.

To determine if a reduction in morbidity and mortality from acute and chronic graft versus host disease (GvHD) can be achieved through use of T-cell depletion techniques without a counterbalancing increase in relapse of leukemia in patients receiving an unrelated donor marrow transplant.
