NCT ID: NCT02676622 Withdrawn - Crohn's Disease Clinical Trials

Autologous Stem Cell Transplant for Refractory Crohn's Disease

Start date: April 2013
Phase: Phase 2
Study type: Interventional

Crohn's disease is an 'auto-immune' disorder of the gut. In this condition the body's own immune system is fighting its gut and causing inflammation and other symptoms. Patients who are refractory (not responding) to the medications usually used to control Crohn's disease (medicines like steroids, azathioprine, methotrexate, cyclophosphamide and antibodies like Infliximab), may consider being part of this study. In this study, the investigators plan to wipe out (ablate) the 'faulty immune system' with medicines (immune-ablation) and then give back the patients own stored stem cells (that have been collected before) - a procedure called autologous (self) stem cell transplant (ASCT). Once the new immune system regrows again from the stem cells, it is hoped that the 'faulty' immune cells do not return again and do not fight the gut leading to remission from symptoms of Crohn's disease. The aim of this treatment therefore, is to reset or re-program the immune system, so that it does not fight the patient's own body. Currently, there are very few trials and experience with this procedure in children and young adults. There have been a few studies that have shown benefit of ASCT procedure in adult patients. In some patients, the benefit lasted for 1-5 years; but 1 in 5 (20%) participants were not taking their medications for the Crohn's disease even 5 years after ASCT. Other 80% needed medications again, but in most cases with better disease control. In order to potentially improve the long term outcomes of ASCT, the investigators are adding another medication (in addition to those used in adult studies) called IL-2 (Aldesleukin), which will be given as an every-other-day injection under the skin (subcutaneous) at very low doses for 6 weeks after the ASCT and can be taken at home. Low dose IL-2 is known to increase a type of immune cell called T-regulatory cells (Tregs) that make immune cells less reactive to self. Study doctors believe that increased population of Tregs after ASCT may lead to a better control of Crohn's disease- higher percentage of cures or disease control for a longer period of time compared to the previous adult trials. Therefore, the goals of this study are- 1. To see if ASCT can be used safely and can provide substantial benefit in young adults who have refractory Crohn's disease. 2. To see if addition of IL-2 after the ASCT is safe and effective.

NCT ID: NCT02249078 Withdrawn - Crohn's Disease Clinical Trials

A Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of 3 Subcutaneous and 1 Intravenous Dose of E6011 in Subjects With Active Crohn's Disease

Start date: December 2014
Phase: Phase 1
Study type: Interventional

This is a multicenter, Phase 1b, randomized, double-blind, placebo-controlled, sequential-cohort, multiple ascending dose (MAD) study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of 3 subcutaneous and 1 intravenous dose of E6011 in subjects with active Crohn's disease (CD). Thirty-two subjects will be randomized to one of 4 dose cohorts (8 per cohort) and will receive E6011 or placebo for 10 weeks. The first 3 cohorts will receive E6011 or placebo via subcutaneous injection and the last cohort will receive E6011 or placebo by intravenous injection. The ratio of E6011 to placebo within each cohort will be 3:1. The study has 2 phases: Prerandomization and Randomization.

NCT ID: NCT02225795 Withdrawn - Crohn's Disease Clinical Trials

Pilot Study of Stem Cell Transplantation for Children and Young Adults With Refractory Crohn's Disease.

Start date: August 2014
Phase: N/A
Study type: Interventional

This is a study for people with Crohn's Disease (CD) that are not responsive to standard treatment. CD is a chronic disease with an auto-immune component that goes away and relapses over the years and causes lifelong impairment of health and quality of life. Regardless of the therapy used some patients remain seriously ill with active disease after multiple therapeutic options have been exhausted. There is currently no drug that will cure CD. Drug treatment is focused on controlling symptoms. Another treatment is to perform surgery but again this does not lead to cure and is often linked to infection, short gut syndrome problems and psycho-social and cosmetic issues. Therefore, a treatment that does not involve surgery or long-term drug treatment may be beneficial especially to young adults. Hematopoietic stem cell transplantation (HSCT) has been of value in other auto-immune diseases and it is possible that it could be of value in CD. This is a pilot study to determine if HSCT is safe and effective for children and young adults with severe CD. For this study the stem cells will come from the patient. This is called an autologous transplant. The patient will undergo collection and storage of his/her peripheral blood stem cells (PBSC). The patient will be given drugs to move (or mobilize) the stem cells from his/her bone marrow into his/her blood where they will be collected on a machine called apheresis (similar to dialysis.) The cells will be stored and given back to the patient about 1 month after collection.

NCT ID: NCT01897090 Withdrawn - Crohn's Disease Clinical Trials

A Crohn's Disease Diet to Reduce Symptoms of Crohn's Disease

Start date: January 2013
Phase: N/A
Study type: Interventional

A 16-week randomized, pilot study to determine if an elimination diet reduces symptoms of Crohn's disease. Sixty (60) adult patients (18-75 yrs) with a mild or moderate Crohn's Disease Activity Index (CDAI) of 150-450, will be recruited through the GI practices at Johns Hopkins University. Patients agree not to be on any other major treatments, with the exception of consistent/stable doses of 5-aminosalicylate (ASA) drugs/other medications during the course of the study and will obtain their physician's permission.They will be divided into a treatment and standard diet group: thirty (30) patients will be on the "Crohn's Disease Diet" (primarily an "anti-inflammatory diet that is an elimination diet - gluten-free, casein-free based with limited carbohydrate) and thirty (30) patients will be given the Dietary Guideline recommendations and similar dietary counseling attention. To assess the clinical efficacy and tolerance of the trial population, patients will be monitored by two office visits (at 0 and 12 weeks) by visits with the Clinical Research Unit (CRU) registered dietitians (RDs) at 0, 6, 12, and 16 weeks (4 weeks after the end of the study) for blood and dietary data collection. Clinical endpoints will be Crohn's disease Activity Index (CDAI) scores (remission < 150; mild = 150-220; moderate = 220-450; severe = 450+), C-Reactive Protein (CRP) values (0-0.8 mg/L), sedimentation rate /(male: 15-20 mm/hr, female: 20-30 mm/hr)/, possibly interleukin-6(/normal value: <10pg/ml)/, Overall Quality of Life (QOL) through the Inflammatory Bowel Disease Questionnaire (IBDQ), Dudley IBD Symptom Questionnaire (DISQ) surveys, and Brown's Gastrointestinal Quality of Life (QOL) Questionnaire, and health care costs measured by a health care cost questionnaire.

Crohn's Extent of Resection Trial

CERT
Start date: June 2013
Phase: N/A
Study type: Interventional
