Clinical Trials

This study is for participants who have received up to three islet cell infusions as a previous participant in the ITN005CT study. Study participants will receive a maintenance immunosuppressive treatment regimen consisting of a combination of orally administered drugs (tacrolimus (Prograf®), sirolimus (Rapamune®), mycophenolate mofetil (MMF, Cellcept®), and/or mycophenolic acid (MPA, Myfortic®).) This protocol provides a way to supply these immunosuppressive medications to subjects whose islets continue to function and make C-peptide.

This is a follow-on study to the ITN’s LEAP trial to evaluate the persistence of tolerance to peanut, and whether continued consumption of peanuts throughout life is required in order to be able to safely eat peanuts without reacting.

The purpose of this study is to determine whether Immucothel, a Keyhole Lymphocyte Antigen (KLH) product, can trigger an immune response when ingested orally and create "oral tolerance" to KLH. If not, Immucothel will be tested with another agent to enhance the immune response.

GRASS is a clinical research study looking at long-term immunity from the symptoms of hay fever. The study is testing the effectiveness of two commercially available tolerance-increasing treatments.

The purpose of the RESTARRT study is see if a combination of two drugs, (ATG and rituximab), given at the time of the transplant surgery, will help reduce or eliminate the need for long-term immunosuppressive medication.

The purpose of this trial is to test whether a drug called alefacept will slow or halt destruction of the beta cells in the pancreas. If the destruction of the beta cells is stopped, the patients might be able to produce insulin on their own longer which could stop or slow the progression of their type 1 diabetes.

This is an observational study for people who have received a kidney transplant within the past 1 to 5 years. Researchers in this study are looking for a certain pattern of genes and cells in the blood that has been found in a group of rare transplant patients who do not need immunosuppression.

The RETAIN study is evaluating a protein called alpha-1 antitrypsin (AAT) in recently diagnosed type 1 diabetes patients.

This study aims to identify which study participants - all of whom previously received a liver transplant under Campath-1H immunosuppression - exhibit specific tolerogenic genotypes. Our hypothesis is that patients who exhibit these genotypes might be good candidates for future immunosuppression withdrawal.

This study will examine the safety and effectiveness of a combination kidney and bone marrow transplant from a relative with the same (or nearly the same) blood cell type as the transplant recipient. An investigational medication will be given prior to and after the transplant to help protect the transplanted kidney from attack by the body's immune system.

The HALT-MS study is investigating an experimental treatment of intensive immunosuppression followed by a transplant of the participant’s own stem cells, to see whether it can stabilize multiple sclerosis. Bone marrow CD34+ stem cells are collected from the participant, and transplanted back into the body following treatment with high doses of chemotherapy drugs. This study is for individuals with relapsing-remitting or progressive-relapsing MS, who have experienced relapses while on other MS treatments.

This study is for people with systemic lupus who have developed complications in their kidneys, called 'lupus nephritis.' The study will determine whether adding the experimental medication abatacept to standard cyclophosphamide therapy is more effective in improving lupus nephritis than standard cyclophosphamide therapy by itself.

This study aims to evaluate the safety and tolerability of a 5 mg dose of the study drug, NBI-5788, for treatment of relapsing-remitting multiple sclerosis patients. A prior phase 2 trial conducted with this drug demonstrated suggestive evidence of treatment benefit with a 5 mg dose of NBI-5788.

This clinical trial is being performed in collaboration with the Finnish Diabetes Prediction and Prevention project and is studying individuals in various stages of prediabetes who receive intranasal insulin as part of a secondary prevention trial. The ITN is funding the support of additional laboratory studies to identify biomarkers that can predict the onset of type 1 diabetes and to learn more about the natural history of the disease.

Immunosuppressive drugs are all that separate transplant recipients from rejecting their transplanted organs. The ITN Registry of Tolerant Kidney Transplant Recipients is searching for those rare kidney transplant recipients who have stopped their immunosuppression, but for some reason have not rejected their transplants. If you have received a kidney transplant and have been off all immunosuppressive medications for 1 year and have good kidney function, or if you received your kidney from an identical twin, you may be eligible to participate.

This study seeks to optimize and standardize an existing assay which allows the T-cell response directed against in transplant recipients who undergo immune tolerance induction. This study employs a rapid laboratory test that would enable the transplant physicians to look at the patient's immune response to this model virus.

This trial investigates the landscape of blood T lymphocytes in patients with active forms of multiple sclerosis. The goal of the study is to demonstrate T cell receptor (TCR) patterns that are specific for disease activity at the patient level and then to use this “TCR signature” to follow regulation of auto reactive T cells, particularly during tolerance induction.

This is a phase I trial in individuals who have been diagnosed with type 1 diabetes within the previous 3-48 months. The study is testing whether two immune system modifying drugs are safe when used in combination and if they have immune altering effects that indicate they can halt the progression of type 1 diabetes.

hOKT3gamma1 (Ala-Ala) is a man-made antibody that is commonly used to prevent organ rejection. The purpose of this study is to determine whether hOKT3gamma1 (Ala-Ala) is safe and effective in psoriatic arthritis patients who are unable to control their arthritis with methotrexate or azathioprine.

Antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis is the most common type of small blood vessel inflammation in adults. ANCA-associated vasculitis includes Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA). Rituximab is a man-made antibody used to treat certain types of cancer. The purpose of this study is to determine the effectiveness of rituximab in treating adults with WG and MPA.
