Safety and Efficacy of Stem Cell Transplantation for Treatment of Liver Cirrhosis

October 25, 2012 updated by: General Hospital of Chinese Armed Police Forces

Safety and Efficacy of Umbilical Cord Mesenchyma Stem Cell Transplantation in Liver Cirrhosis Patients

Mainstream of current treatment of liver cirrhosis is liver transplantation, but there are high cost, risk and immune rejection and other issues. Umbilical cord mesenchyma stem cell with self-and directed differentiation capacity can effectively rescue experimental liver failure and contribute to liver regeneration, which suggests the feasibility of stem cell transplantation therapy. In this study, the safety and efficacy of umbilical cord mesenchyma stem cell transplantation through interventional procedures in patients liver cirrhosis will be evaluated.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study included three research centers, each center were carried out 25 cases of liver cirrhosis in patients with stem cell transplantation. All the selection and exclusion criteria are same, data summary and analysis will be complete by the epidemiological commissioner.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating).
