Active clinical trials for "Immune System Diseases"

This is a single centre randomised, placebo-controlled phase 2 study in which 96 children age 4 to 16 years with moderate to severe, longstanding allergic eczema will be enrolled.

In this protocol, the investigators hypothesize that the combination of intravenous busulfan and melphalan with carfilzomib will be an effective preparative regimen with acceptable toxicity for participants with multiple myeloma who are candidates for autologous stem cell transplantation. To test this hypothesis, the investigators designed a phase I/II trial combining IV busulfan 130 mg/m2 plus melphalan 140 mg combined with escalating doses of carfilzomib ranging from 20 mg/m2 to 45 mg/m2. These results will be compared with the center's historical controls of participants treated with melphalan, busulfan and bortezomib.

Rivaroxaban Versus Warfarin for Stroke Patients With Antiphospholipid Syndrome, With or Without SLE (RISAPS): a Randomised, Controlled, Open label, Phase II/III, Non-inferiority Trial. 140 patients will be randomised with a ratio of 1:1 to receive either: Rivaroxaban 15mg twice daily orally for 24 months or Warfarin (standard of care in the RISAPS trial) to maintain a target INR of 3.5 (range 3.0-4.0) for 24 months. The primary outcome of the trial is the rate of change in brain white matter hyperintensity (WMH) volume between baseline and 24 months follow up, assessed on brain magnetic resonance imaging (MRI), a surrogate marker of ischaemic damage.

This research study is studying a drug as a possible treatment for Bronchiolitis Obliterans Syndrome (BOS) after having an Allogeneic Hematopoietic Cell Transplantation (HCT).

Effect of Some Drugs on Rheumatoid Arithritis Activity.

Immunotherapy offers an extremely precise approach with the potential to eliminate cancer cells specifically. The newly designed CD19 targeted ICAR19 T cells can specifically kill CD19+ tumor cells. ICAR19 CART used the second generation of CART designation. In this study, the participants will receive several doses of autologous ICAR19 T cells and the investigators will determine the safety and therapeutic effects of these cells.

Background: A person s tumor is studied for mutations. When cells are found that can attack the mutation in a person s tumor, the genes from those cells are studied to find the parts that make the attack possible. White blood cells are then taken from the person s body, and the gene transfer occurs in a laboratory. A type of virus is used to transfer the genes that make those white blood cells able to attack the mutation in the tumor. The gene transfer therapy is the return of those white blood cells back to the person. Objective: To see if gene transfer therapy of white blood cells can shrink tumors. Eligibility: People with certain metastatic cancer for which standard treatments have not worked. Design: Participants may complete screening under another protocol. Screening includes: Getting tumor cells from a previous procedure Medical history Physical exam Scans Blood, urine, heart, and lung tests The study has 8 stages: Screening tests repeated over 1-2 weeks. Participants will have leukapheresis: Blood is removed by a needle in one arm. A machine removes white blood cells. The rest of the blood is returned by a needle in the other arm. Care at home over approximately 12 weeks. Stopping therapy for 4-6 weeks while their cells are changed in a lab. Hospital stay approximately 3-4 weeks for treatment. An IV catheter will be placed in the chest to administer drugs. Patients on Arm 2 of the study will receive the first dose of pembrolizumab while in the hospital. Three additional doses will be given after the cell infusion 3 weeks apart. Receiving changed cells by catheter. Then getting a drug over 1-5 days to help the cells live longer. Recover in the hospital for 1-2 weeks. Participants will get drugs and have blood and urine tests. Participants will take an antibiotic and maybe an antiviral for at least 6 months after treatment. They will have repeat screening tests at visits every few months for the first year, every 6 months for the second year, then as determined.

Background: Human immunodeficiency virus (HIV) attacks the immune system. Some people with HIV have a low CD4+ T-cell count despite taking antiviral medicines that control HIV replication. These cells fight disease, so a low count makes it easier for people to become sick. Researchers want to see if a new drug can improve the immune system, including T cells. The drug is called pembrolizumab Objective: To see if pembrolizumab is safe to use in people with HIV who have a low CD4+ T cell count despite taking medcines that control HIV replication, and to see if it strengthens the immune system. Eligibility: People age 18 years or older with HIV who are taking antiretroviral drugs as treatment, have blood HIV levels below detection limits of commercial assays, and have a low CD4+ T-cell count (below 350 cells/mm3). Design: Participants will be screened with: Medical history Physical exam Heart, blood, and urine tests Sexually active participants must use 2 kinds of birth control. Participants will have leukapheresis. Blood will be removed through a needle in one arm. A machine will remove white blood cells. The rest of the blood will be returned into the other arm. Participants will have a baseline visit. They will have blood tests. They may have a pregnancy test. A needle will insert a thin plastic tube (IV) into an arm vein. The participants will get the study drug or a placebo through the IV for 30 minutes. They will be watched for a couple hours after. Participants will have 11 follow-up visits over the next 48 weeks. They will have a physical exam, vital signs, medical review, and blood tests. Participants may have another leukapheresis. Participants will be called every 12 weeks after their last follow-up visit to talk about how they feel and their health. Participation ends after the week 96 phone call. ...

The purpose of this study is to determine the clinical benefit and characterize the safety profile of tabelecleucel for the treatment of Epstein-Barr virus-associated post-transplant lymphoproliferative disease (EBV+ PTLD) in the setting of (1) solid organ transplant (SOT) after failure of rituximab and rituximab plus chemotherapy or (2) allogeneic hematopoietic cell transplant (HCT) after failure of rituximab.

This phase II trial studies how well donor umbilical cord blood transplant with ex-vivo expanded cord blood progenitor cells (dilanubicel) works in treating patients with blood cancer. Before the transplant, patients will receive chemotherapy (fludarabine, cyclophosphamide and in some cases thiotepa) and radiation therapy. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood 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.
