NCT ID: NCT03333486 Active, not recruiting - Clinical trials for Acute Myeloid Leukemia

Fludarabine Phosphate, Cyclophosphamide, Total Body Irradiation, and Donor Stem Cell Transplant in Treating Patients With Blood Cancer

Start date: December 7, 2017
Phase: Phase 2
Study type: Interventional

This phase II trial studies how well fludarabine phosphate, cyclophosphamide, total body irradiation, and donor stem cell transplant work in treating patients with blood cancer. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy 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. The donated stem cells may also replace the patient?s immune cells and help destroy any remaining cancer cells.

NCT ID: NCT02757911 Active, not recruiting - Clinical trials for X-Linked Chronic Granulomatous Disease

Gene Therapy for X-linked Chronic Granulomatous Disease

Start date: March 2016
Phase: Phase 1/Phase 2
Study type: Interventional

X-linked chronic granulomatous disease (X-CGD) is a rare genetic disorder, which affects boys. It is a primary immunodeficiency disorder which results from an inability of the white blood cells called phagocytic cells (or phagocytes) to kill invading bacteria and fungi. These cells have difficulty forming the free radicals (most importantly the superoxide radical due to defective phagocyte NADPH oxidase complex) which are important in the killing of ingested pathogens. In X-CGD (which accounts for two thirds of CGD patients), the defect lies in a gene which makes up a critical part of the NADPH-oxidase complex (the catalytic subunit; gp91-phox protein). Therefore they kill bacteria and fungi poorly, and the patients suffer from severe and recurrent infections. This also results in inflammation which can damage parts of the body such as the lung and gut. In many cases, patients can be adequately protected from infection by constant intake of antibiotics. However, in others, severe life-threatening infections break through. In some cases, inflammation in the bowel or urinary systems results in blockages which cannot be treated with antibiotics, and which may require the use of other drugs such as steroids. Development of curative treatments for CGD is therefore of great importance.

NCT ID: NCT02629120 Active, not recruiting - Clinical trials for Chronic Granulomatous Disease Transplant

High Dose Peripheral Blood Stem Cell Transplantation With Post Transplant Cyclophosphamide for Patients With Chronic Granulomatous Disease

Start date: December 17, 2015
Phase: Phase 1/Phase 2
Study type: Interventional

Chronic granulomatous disease (CGD) affects white blood cell function. Currently, the only curative treatment is bone marrow transplant to replace the abnormal stem cells with new ones (donor cells) capable of making a normal immune system. Transplant problems include graft versus host disease (GvHD) and graft rejection. With GvHD, donor cells attack the recipient s normal tissue. Researchers want to use preparation drugs and a high cell dose to increase graft success. They want to use 2 immunosuppressive drugs (cyclophosphamide and sirolimus) to lessen the risk of GvHD.

NCT ID: NCT01855685 Active, not recruiting - Clinical trials for X-Linked Chronic Granulomatous Disease

Gene Therapy for X-linked Chronic Granulomatous Disease (X-CGD)

CGD
Start date: June 24, 2013
Phase: Phase 1/Phase 2
Study type: Interventional

X-linked chronic granulomatous disease (X-CGD) is a rare genetic disorder, which affects boys. It is caused by an error in a gene that makes part of the immune system. The basic defect lies in specialised white blood cells called phagocytic cells (or phagocytes), which are responsible for protection against infection by destroying invading bacteria and fungi. They do this by pouring large amounts of substances similar to bleach onto these organisms. In CGD, there is a defect in the system that makes the bleach, called the NADPH-oxidase. In X-CGD (which accounts for two thirds of patients), the defect lies in a gene which makes up a critical part of the NADPH-oxidase (known as gp91-phox), and the cells cannot make bleach-like substances. Therefore they kill bacteria and fungi poorly, and the patients suffer from severe and recurrent infections. This also results in inflammation which can damage parts of the body such as the lung and gut. In many cases, patients can be adequately protected from infection by constant intake of antibiotics. However, in others, severe life-threatening infections break through. In some cases, inflammation in the bowel or urinary systems results in blockages which cannot be treated with antibiotics, and which may require the use of other drugs such as steroids. Development of curative treatments for CGD is therefore of great importance.

NCT ID: NCT00778882 Active, not recruiting - Clinical trials for Chronic Granulomatous Disease

Gene Therapy for Chronic Granulomatous Disease in Korea

Start date: January 2007
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this study is to evaluate the safety and efficacy of administration of autologous hematopoietic stem cells transduced with MT-gp91 retroviral vector for patients with X-linked chronic granulomatous disease.

NCT ID: NCT00564759 Active, not recruiting - Clinical trials for Granulomatous Disease, Chronic

Gene Therapy for Chronic Granulomatous Disease

CGD
Start date: January 2004
Phase: Phase 1/Phase 2
Study type: Interventional

The aim of the study is to evaluate the side effects and risks after infusion of retroviral gene corrected autologous CD34+ cells of the peripheral blood of chemotherapy conditioned (busulphan)patients with chronic granulomatous disease (CGD). Also gene corrected and functional active granulocytes in the peripheral blood and the engraftment in the bone marrow of the patients will be monitored an documented.
