About this study

Official title: Autologous Bone Marrow Stem Cells Infusion Through Hepatic Artery in Open Abdominal Portal Hypertension Surgery for the Treatment of Liver Cirrhosis: a Prospective, Non-randomized, Controlled Study

In recent years, the safety and efficacy of autologous bone marrow stem cells infusion (ABMSCi) therapy were confirmed. The investigators attempted to infuse autologous bone marrow stem cells (ABMSC) through inserting a catheter into right gastric artery as far as proper hepatic artery after finishing open abdominal portal hypertension surgery. The present study was designed to treat bleeding from esophageal varices and hypersplenism and hopefully to improve the liver function as well.

Read the detailed description
  1. ABMSC mobilization and harvest
  • For harvesting more ABMSC, ABMSC mobilization was induced by rhG-CSF (Gran○R), administered subcutaneously at a dose of 300μg daily for three consecutive days before open abdominal portal hypertension surgery.
  • Bone marrow (160-200ml) of the patients was harvested from both posterior superior iliac according to standard procedures under local anaesthesia and was collected in a plastic bag containing heparin.
  1. Open abdominal portal hypertension surgery
  • Immediately after the harvest of ABMSC, the modified Sugiura procedure was performed for the patients who were assigned to the study group. The same surgical procedure was also performed for the control group (without harvest of ABMSC and ABMSC infusion).
  1. ABMSC separation and infusion
  • While performing the portal hypertension surgery, ABMSC was separated and purified in a class 10,000 clean laboratory. After fat and bony particles were removed by filtration, collected cells were moved to a cell-processing device. We used the reagent kit ([Patent Number] ZL 2006 1 0106875.5; [Number of Criteria Applicable] YZB/NING YIN 0008-2008; [Researcher and Developer] Wealthlin Science \& Technology Inc., Canada; [Producer] Ningxia Zhonglianda Biotech Co., Ltd.). The reagents adopt the method of negative cells collection. Take the cells which intended to remove as target cells, and carry out the removal step-by-step. On the basis of this method, red blood cells, blood platelets, blood plasma will be completely removed with part of white cells and lymphocytes being remarkably removed as well while all the stem cells / progenitor cells are being well retained.
  • The nucleated cell (white blood cell) count of final ABMSC was measured by an automated complete blood count instrument and flow cytometry analysis. The number of mononuclear cells was counted manually under a microscope by Wright-Giemsa stain method. CD34 positive cells were determined by flow cytometry analysis.
  • The time of ABMSC separation and purification was 2.5-3 hours which had to be completed before the conclusion of portal hypertension surgery (3-3.5 hours). ABMSC was added to 10 ml saline and well mixed by shaking the vial gently. Before incision closure, the right gastric artery or right gastroepiploic artery was selected and a catheter was inserted. The catheter was pushed to reach the proper hepatic artery. The diameter of the catheter is 1.4mm, it is thin enough to easily been inserted to right gastric artery or right gastroepiploic artery (central venous catheterization, REF product NO.ES-04218, Arrow International, Inc.). The mixture of saline and AMBC was infused into hepatic artery at uniform speed for about two minutes. The catheter was removed after the ABMSCi. The puncture point of the right gastric artery was repaired using blood vessel suture or transfixed.
  1. Statistical analysis - Categorical data are presented as absolute values and percentages, whereas continuous data are summarized as mean and Standard Deviation. Statistical analysis was performed using t-test for paired or unpaired samples. Time courses of measurements of liver function parameters were analyzed by repeated-measures ANOVA. The analyses were performed using the SPSS 15.0 statistical package (SPSS Inc., Chicago, IL, USA). All statistical analyses were based on two-tailed hypothesis tests with a significance level of p< 0.05.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Autologous bone marrow stem cells infusion (ABMSCi) plus abdominal portal hypertension surgery and open abdominal portal hypertension surgery in people with Liver Cirrhosis and Portal Hypertension, run by Wenzhou Medical University at 1 site in China.

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 6 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 22 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Results are not available in the source record.

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

Contact qiqiang zeng, MD (86-0577-88069307, zengqiqiangwz@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Child-pugh score (time frame: 1 month after treament). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01560845, which also lists 4 linked publications.

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 22 Mar 2012.
