Clinical Trials:
1. A One Year, Multicenter, Partially Blinded, Double-Dummy,
Randomized Study to Evaluate the Efficacy and Safety of FTY720
Combined with Reduced-Dose or Full-Dose Neoral® and Corticosteroids
versus Mycophenolate Mofetil (MMF, Cellcept®) Combined
with Full-Dose Neoral® and Corticosteroids, in de novo
Adult Renal Transplant Recipients.(FTY720)
This exciting study sponsored by Novartis and involving renal
transplant patients, will evaluate the effectiveness and safety
of a new kind of immunosuppressant. FTY720 works in a way
that preserves infection fighting mechanisms in the body while
preventing rejection of the transplanted kidney. Dr. Robert
A. Fisher is the Principal Investigator.
2. A Multicenter, Randomized, Double blind, Parallel Group
Trial to Demonstrate the Efficacy of Fondaparinux Sodium in
Association with Intermittent Pneumatic Compression Versus
Intermittent Pneumatic Compression Used Alone for the Prevention
of Venous Thromboembolic Events in High-Risk Patients Undergoing
Major Abdominal Surgery (EFC3558)
This clinical trial, sponsored by Sanofi-Synthelabo, studies
the effectiveness of the drug Fondaparinux Sodium in prevention
of deep vein thrombosis following abdominal surgery. This
drug has already been found to be effective following orthopedic
surgery and is FDA approved for this use. It is hoped that
the drug will prove a safe, effective therapy for patients
at risk for this potentially devastating complication of abdominal
surgery. The Principal Investigator is Dr. Robert A. Fisher.
3. A Randomized, Open-Label, Comparative Evaluation of Conversion
from Calcineurin Inhibitor Treatment To Sirolimus Treatment
Versus Continued Calcineurin Inhibitor Treatment in Liver
Allograft Recipients Undergoing Maintenance Therapy (0468H-313)
This study, sponsored by Wyeth, will attempt to evaluate
the effectiveness of the immunosuppressant sirolimus for preservation
of renal function in liver transplant patients. Historically,
patients have been converted to sirolimus immunosuppressive
therapy at the onset of renal insufficiency related to calcineurin
inhibitors. This study will evaluate efficacy of sirolimus
in the prevention of renal insufficiency. Dr. Robert A. Fisher
is the Principal Investigator.
5. Adult to Adult Living Donor Liver Transplantation Cohort
Study
Sponsored by the National Institutes of Health, this is a
multi-center, five year study of both living donors and their
recipients. It includes a retrospective arm that will entail
extensive data retrieval and a prospective arm to track patient
progress. There is a sub-study, written by Dr. Robert Fisher
and Dr. Valeria Mas that will study Hepatocellular Carcinoma
on the molecular level in this patient population as well.
Dr. Robert A. Fisher and Dr. Mitchell Shiffman are Co-Principal
Investigators in this study.
6. Hepatic Regeneration in Donors and Recipients following
Living Donor Liver Transplantation
This study is to evaluate regeneration of liver tissue in
both recipients and donors of transplanted livers. It includes,
for example, determination of which factors are most critical
to regeneration, to discover markers that will parallel normal
regeneration and the relationships that may occur between
regeneration and growth factors. Dr. Robert A. Fisher is the
Principal Investigator.
7. The Use of Human Hepatocyte Transplantation as a Life
support Bridge in Terminal Liver Failure
The purpose of this research is to gain knowledge about the
result of infusing liver cells, carefully matched to blood
type, into a subject’s body. The hope is that is procedure
will aid functions of the liver and prevent death, enable
a transplant procedure to be carried out if a donated liver
becomes available and lessen complications in postoperative
recovery. The Principal Investigator is Dr. Robert A. Fisher.
8. Cryptococcus neoformans Infection in Organ Transplant
Recipients: Impact of Immunosuppressive Agent Resistance and
Virulence Factors on Tissue Tropism, and Outcome
This study is being undertaken with Dr. Nina Singh at the
University of Pittsburg under and NIH grant along with 14
other sites in the country. It will study several aspects
of the infective agent Cryptococcus to try to discover a better
way to fight the organism in transplant patients. Dr. Robert
Fisher is the Principal Investigator.
9. Liver Tissue Procurement and Distribution System (LTPADS)
This NIH sponsored program is in place to procure, store
and distribute normal and diseased liver tissue to researchers
worldwide. Dr. Robert A. Fisher is the Principal Investigator.
10. Studies of Pediatric Liver Transplantation (SPLIT), A
Multicenter Prospective Study to Collect Scientific Data on
Pediatric Liver Transplantation
This NIH sponsored study is designed to help the transplant
community better understand the problems and potential solutions
surrounding liver transplantation in children. Data is collected
on patient graft survival, incidents of rejection, growth,
immunosuppressants, risk factors, mortality and morbidity.
The data is periodically analyzed and shared with the community.
Dr. Robert A. Fisher is the Principal Investigator.
11. Transplant Registry
The Transplant Registry is an IRB approved data base with
information gathered from medical records of patients with
conditions relating or leading to transplantation. This data
base has been invaluable in evaluating efficacy of treatments
and in the publication of papers for professional journals.
Dr. Robert Fisher is the Principal Investigator.
Laboratory Studies:
1. Liver cells transplantation
In our research laboratories, we established a steady method
to isolate human liver cells. Liver cells transplantation
has been used in our group to bridge the patients who have
liver function failure. By using human liver cells, we genetically
engineered human insulin gene and made the cells expressing
mature, functional human insulin. The goal is to create factories
of blood sugar-regulating cells in the liver that one day
may be used in the treatment of patients with severe diabetes.
Because liver cells are the only cells in the body that can
continually regenerate, they are not vulnerable to autoimmune
disease that destroys islet cells in people with diabetes.
Dr. Robert A. Fisher is the Principal Investigator.
2. Organ Transplant Tolerance Studies
Animal model of renal transplantation was created in our
research laboratories. Kidney of ACI rat was transplanted
into Lewis rat. Mechanisms of tolerance of allografts were
investigated by analysis of functional data, renal histological
structures and cytokines profiles. Our past studies have demonstrated
that Th-2 cytokines (IL-4, IL-10) played key role in the long-term
tolerance. One of our ongoing projects is the investigation
of the early stages of cytokines profile. These studies could
improve our understanding of transplant tolerance. Dr. Robert
A. Fisher is the Principal Investigator.
