Trial summary

This disease is believed to be due to immune cells, cells which normally protect the body, but are now destroying the bile ducts in the liver. When the ducts are damaged, bile builds up in the liver and damages liver tissue. Over time, the disease can cause cirrhosis and may make the liver stop working. Read more about this study

About this study

Official title: Non-myeloablative Allogeneic Hematopoietic Stem Cell Transplantation in Patients With Primary Biliary Cirrhosis: A Phase I Study

This disease is believed to be due to immune cells, cells which normally protect the body, but are now destroying the bile ducts in the liver. When the ducts are damaged, bile builds up in the liver and damages liver tissue. Over time, the disease can cause cirrhosis and may make the liver stop working. This study is designed to examine whether treating patients with high dose Cyclophosphamide and Fludarabine (drugs which reduce the function of your immune system) and CAMPATH-1H (a protein that kills the immune cells that are thought to be causing PBC), followed by return of blood stem cells that have been previously collected from patient brother or sister will stop or reverse the disease. The purpose of the Cyclophosphamide, Fludarabine and CAMPATH-1H is to decrease immune system. The purpose of the stem cell infusion is to restore blood production, which will be severely impaired by the Cyclophosphamide, Fludarabine and CAMPATH-1H, and to produce a normal immune system that will no longer attack the body.

Read the detailed description

There will be no randomization in this study. All subjects who are determined to be eligible for the study treatment will receive high dose cyclophosphamide, fludarabine and CAMPATH-1H followed by infusion of allogeneic peripheral blood stem cells. The procedures the subject will undergo are as follows:

  1. Physician visit to determine potential eligibility for the study. Subjects will be evaluated by a transplant physician. They will have a complete physical examination and will provide a full medical history at these visits. In addition, subjects will be asked to complete a quality of life Questionnaire . Finally, the study will be described in detail by the transplant physician and nurse and the consent form will be provided to be taken home to read.
  2. HLA Testing. In order to proceed on this study, subjects will need to have a HLA identical matched sibling donor. The subject and his or her siblings will need to undergo HLA typing in order to determine whether there is a match or Cord blood stem cells will be obtained from the New York Blood Center Cord Blood Registry which is an internationally recognized registry or, if a match is not available, from Stemcyte, a commercial registry that specializes in minority donors. One unit of HLA matched cord blood unit will be infused on day zero.
  3. Insurance verification. Subjects who remain interested in pursuing the study treatment and who have severe scleroderma that is following a progressive course will proceed to the insurance verification phase. Third party payment or self-pay must be verified before subjects can proceed.
  4. Consent form. Prior to proceeding, the appropriate signatures will be obtained on the consent form. Subjects will be given an opportunity to ask further questions of the attending physician and transplant nurse prior to signing the consent form.
  5. Pre-transplant testing. To determine final eligibility for the study, subjects will undergo a series of tests/procedures. These include: CXR, electrocardiogram, endoscopy , ultrasound of the liver and gallbladder,transvenous liver biopsy, lymphopheresis, pulmonary function test, urinalysis, and blood testing to include CBC; chemistries; liver and kidney function tests; PT; PTT; AMA; viral studies and, for females, a pregnancy test. Subjects will also be evaluated by a dentist at Northwestern Memorial Hospital to rule out any potential sources of infection. All pre-transplant testing is routine medical testing done to verify diagnosis and to insure adequate organ function and absence of viral illnesses which would preclude a safe transplant course. Allogeneic donors will also need to undergo testing in order to determine eligibility to proceed. Testing for donors will include history and physical, electrocardiogram, CXR, urinalysis, CBC, chemistries, PT, PTT, viral studies and, for females, a pregnancy test.
  6. Allogeneic peripheral blood stem cell collection. Allogeneic donors will undergo a routine procedure for the mobilization and collection of peripheral blood stem cells. This includes the subcutaneous administration of G-CSF, to be self-administered as an outpatient, beginning three days prior to the start of peripheral blood stem cell harvesting. The peripheral blood stem cells will be collected as an outpatient in the Blood Center on the fourth day of G-CSF administration. A central line may be placed for this purpose on the first day of leukopheresis. Leukopheresis will be continued on a daily basis (up to four consecutive days) until an adequate number of peripheral blood stem cells have been collected. G-CSF will continue to be administered until leukopheresis is completed. The pheresis catheter will be discontinued when stem cell harvesting is completed. Processed cells will be frozen and stored until they are reinfused after the conditioning regimen.
  7. Study treatment. Prior to the administration of the study treatment, subjects will have a double lumen PICC line placed for the administration of chemotherapy, IV fluids, blood products and the withdrawal of blood samples. The placement of a central catheter is a routine medical procedure. Subjects will then undergo conditioning which will include 4 days of intravenous fludarabine and 4 days of cyclophosphamide and 2 days of CAMPATH-1H. All drugs are FDA approved drugs. The previously collected allogeneic peripheral blood stem cells will be reinfused following the completion of the conditioning regimen.
  8. Post-transplant follow-up. Subjects will have a history and physical by the transplant physician at 6 months, 12 months, and yearly for 5 years. In addition, routine urinalysis and blood testing will be performed at these same intervals to include CBC; chemistries; kidney and liver function tests; AMA; ultrasound of the liver and gallbladder, transvenous liver biopsy, lymphopheresis, and patients will also be asked to complete a SF-36 Questionnaire, NDDK-QA Questionnaire.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Non-myeloablative Hematopoietic Stem Cell Transplantation in people with Primary Biliary Cirrhosis, run by Richard Burt, MD.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 33 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 8 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

No liver-related death or LTx over the 2-year (extended to 5 years) follow-up; Normalization of serum alkaline phosphatase over 6 months;Amelioration of PBC histological stage with reduction of both inflammation and fibrosis scores 42 (time frame: 5 years after transplant). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2012.
