NCT ID: NCT02387151 Completed - Rejection Clinical Trials

Allogeneic Mesenchymal Stromal Cell Therapy in Renal Transplant Recipients

Neptune
Start date: March 2015
Phase: Phase 1
Study type: Interventional

This study will test whether selected allogeneic bone marrow derived MSCs are safe by assessing the composite end point Biopsy Proven Acute Rejection (BPAR)/ graft loss at 12 months.

NCT ID: NCT01298102 Completed - Influenza Clinical Trials

Influenza A/H1N1/2009-adjuvanted Vaccine in Renal Disease Patients

Start date: October 2009
Phase: Phase 4
Study type: Interventional

In 2009, the pandemic influenza A/H1N1 accounted for worldwide recommendations about vaccination. There is no data concerning the immunogenicity nor the security of the adjuvanted-A/H1N1 vaccine in renal disease patients. The aim of this study is to observe the effects of this vaccine on transplanted and hemodialyzed patients.

NCT ID: NCT01208337 Completed - Clinical trials for Evidence of Liver Transplantation

Safety and Efficacy of Alemtuzumab in Pediatric Intestinal Transplantation

Start date: April 2007
Phase: Phase 2
Study type: Interventional

This open-label clinical trial will evaluate the safety and efficacy of Alemtuzumab (Campath, Bayer Corp., Pittsburgh) in children (0-17) and adults (18-25) receiving intestinal transplant. Seventy-five subjects receiving primary or repeat intestine transplantation will be enrolled. Primary endpoints include the incidence and severity of biopsy-proven acute cellular rejection, the incidence of freedom from steroids at 5 years, and the incidence of subjects with steroid-free Tacrolimus at whole blood concentrations < 10 ng/ml. Secondary endpoints include a) incidence and severity of opportunistic infections (CMV and EBV), post-transplant lymphoproliferative disorder (PTLD), and chronic rejection b) use of non-immunosuppressive co-medications, c) time to repopulation of all lymphocyte subsets, d) longitudinal characterization of donor-specific alloreactivity in mixed lymphocyte responses (MLR), to identify the time at which it decreases to a level less than third-party-specific alloreactivity e) longitudinal expression (mRNA) of genes, to identify rejection- and non-rejection-specific genes and f) characterization of whole genome mutations, which show differences in parent-to-child transmission between rejectors and non-rejectors. This will identify rejection- and non-rejection-specific genes bearing genetic variants, which might impact on gene function, and complement candidate gene identification efforts based on SNP transmission.

NCT ID: NCT01207141 Completed - Clinical trials for Liver Transplantation

rATG Induction and Tacrolimus Monotherapy in Pediatric Liver Transplantation

Start date: August 2006
Phase:
Study type: Observational

This open-label clinical trial will evaluate the pharmacodynamics, pharmacogenomics and early efficacy and safety of steroid-free Tacrolimus (TAC) monotherapy and its minimization after induction with rabbit, anti-human thymocyte globulin (rATG, Genzyme, Cambridge, MA) in children and adults with pediatric liver transplantation. Eighty subjects (0-21 years) receiving liver transplantation will be enrolled. Incidence and severity of biopsy-proven acute cellular rejection (ACR) is a primary endpoint as well as time to Tacrolimus whole blood concentrations <8 ng/ml The expected incidence of ACR is 50% and is derived from a non-consecutive subject population (n=40) who received an identical regimen in IND 64555. This incidence is acceptable because the long term sequel of rejection reported with other allografts have not been observed in liver grafts during IND 64555. These risks are further negated by the unique regenerative capacity of the liver allograft. An OBSERVATIONAL arm is being included in this trial. Because the numbers of pediatric liver transplants (LTx) are small in any single center setting, no information is known about relative outcomes on a conventional protocol, in children receiving conventional protocol of steroids+Tacrolimus. The PURPOSE of this additional recruitment is OBSERVATIONAL, only. Therefore, these subjects will NOT be randomized. Rather, by studying all types of patients, the investigators hope to utilize maximally, all available subjects, to understand the relative place of monotherapeutic induction. In turn, this will be the basis for a follow-up comparative, randomized trial.

NCT ID: NCT00743171 Completed - Death Clinical Trials

Long-Term Study On Home Spirometry After Lung Transplantation

Start date: January 2000
Phase: N/A
Study type: Observational

Prospective cohort, mono-center study included electronic data of home spirometry (HS, lung function) of lung transplant recipients

NCT ID: NCT00225394 Completed - Death Clinical Trials

Long Term Use of Valganciclovir for Prophylaxis of CMV Disease in Kidney and Pancreas Transplant Patients

Start date: October 2003
Phase: Phase 4
Study type: Observational

CMV viral disease negatively affects transplant patients. CMV is the most prevalent infection in transplant patients and 3 month drug regimens to prevent the virus have been mostly unsuccessful, usually after the drug has been stopped, the patient develops the viral disease. Extended use of anti-viral drugs may, in fact, may lead to the development of resistant virus. We hypothesize that extended use (12 months) of valganciclovir (Valcyte™)will not only be efficacious but will not be associated with the development of resistant CMV. Sample Size: 100 patients at 3 sites have been enrolled Patient Selection: Adult (>18 years) recipients of cadaveric or living donor kidneys, pancreas, or combine kidney-pancreas transplants. Immunosuppression: To be determined according to each center’s standard protocol (s). Study Drug: Valcyte™ Days 0 – 90: All Patients, 900 mg QD Days 91 – 365: Group 1: 900 mg QD Group 2: 450 mg QD Assessment of Valgancicovir (Valcyte™)Resistant CMV : Serial serum samples (at transplant, 6 weeks, and 3, 6, 9 and 12 months post-transplant) for PCR amplification and DNA sequence analysis from detectable CMV to identify the presence of mutations within the UL97 and UL54 genes. Other Analyses: Additional information will be evaluated relating to the development of CMV disease, development of ganciclovir toxicity, graft rejection or graft loss and patient death. Preliminary information regarding the predictive value of DNA assays for the development of CMV disease will be evaluated.
