Background: - Some people with advanced heart and lung disease have heart and lung transplants. But the organs are often rejected. When this happens, the organ recipients must have repeated biopsies. These are invasive and expensive. Researchers want to see if a blood test can predict rejection and take the place of biopsies. The test shows how much donor DNA is in a recipient s blood. Objective: - To see if a new blood test can be used instead of biopsies to diagnose rejection after transplant. Eligibility: - Adults 18 years and older who are on the lung or heart transplant waitlist. Design: Participants will have about 4 teaspoons of blood drawn from the arm before having their transplant. Researchers will collect demographic data about participants. They will also collect basic medical information about their condition. After surgery, while still in the hospital, participants will have 2 teaspoons of blood drawn twice a week until they go home. At each biopsy visit after the transplant, participants will have 4 teaspoons of blood drawn for testing for up to 5 years. Read Less

This phase II/III trial studies how well radiation therapy works when given together with cisplatin, docetaxel, cetuximab, and/or atezolizumab after surgery in treating patients with high-risk stage III-IV head and neck cancer the begins in the thin, flat cells (squamous cell). Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The purpose of this study is to compare the usual treatment (radiation therapy with cisplatin chemotherapy) to using radiation therapy with docetaxel and cetuximab chemotherapy, and using the usual treatment plus an immunotherapy drug, atezolizumab.

This study is designed to explore the genetics and pathophysiology of diseases presenting with intermittent fever, including familial Mediterranean fever, TRAPS, hyper-IgD syndrome, and related diseases. The following individuals may be eligible for this natural history study: 1) patients with known or suspected familial Mediterranean fever, TRAPS, hyper-IgD syndrome or related disorders; 2) relatives of these patients; 3) healthy, normal volunteers 7 years of age or older. Patients will undergo a medical and family history, physical examination, blood and urine tests. Additional tests and procedures may include the following: X-rays Consultations with specialists DNA sample collection (blood or saliva sample) for genetic studies. These might include studies of specific genes, or more complete sequencing of the genome. Additional blood samples a maximum of 1 pint (450 ml) during a 6-week period for studies of white cell adhesion (stickiness) Leukapheresis for collecting larger amounts of white cells for study. For this procedure, whole blood is collected through a needle in an arm vein. The blood flows through a machine that separates it into its components. The white cells are removed and the rest of the blood is returned to the body through another needle in the other arm. Patients may be followed approximately every 6 months to monitor symptoms, adjust medicine dosages, and undergo routine blood and urine tests. They will receive genetic counseling by the study team on the risk of having affected children and be advised of treatment options. Participating relatives will undergo a medical and family history, possibly with a review of medical records, physical examination, blood and urine tests. Additional procedures may include a 24-hour urine collection, X-rays, and consultations with medical specialists. A DNA sample (blood or saliva) will also be collected for genetic studies. Additional blood samples of no more than 550 mL during an 8-week period may be requested for studies of white cell adhesion (stickiness). Relatives who have familial Mediterranean fever, TRAPS, or hyper-IgD syndrome will receive the same follow-up and counseling as described for patients above. Normal volunteers and patients with gout will have a brief health interview and check of vital signs (blood pressure and pulse) and will provide a blood sample (up to 90 ml, or 6 tablespoons). Additional blood samples of no more than 1 pint over a 6-week period may be requested in the future.... Read Less

This is a pediatric kidney transplant study comparing the safety and efficacy of an immunosuppressive regimen of belatacept and sirolimus to tacrolimus and Mycophenolate Mofetil (MMF). Two hundred participants will be randomized (1:1) to one of two groups within 24 hours following the transplant procedure. The duration of the study from time of transplant to the primary endpoint is 12-24 months. Read Less

The purpose of this study is to evaluate the effect of RBT-1 on reducing the risk of post-operative complications in subjects undergoing cardiac surgery on cardiopulmonary bypass (CPB). A sub-study will also be conducted to evaluate the pharmacokinetic (PK) profile of a single administration of RBT-1 by means of a popPK approach in subjects scheduled to undergo cardiac surgery.

The purpose of the study is to assess the efficacy of durvalumab plus tremelimumab in combination with chemotherapy compared with pembrolizumab in combination with chemotherapy in metastatic NSCLC patients with non-squamous histology who have mutations and/or co-mutations in STK11, KEAP1, or KRAS.

The goal of this clinical study is to evaluate povetacicept in adults with autoimmune cytopenias of immune thrombocytopenia, autoimmune hemolytic anemia, and cold agglutinin disease to determine if povetacicept is safe and potentially beneficial in treating these diseases. During the study treatment period participants will receive povetacicept approximately every 4 weeks for 6 months, with the possibility of participating in a 6-month study treatment extension period.
