Evaluate Safety and Efficacy of Autologous Bone Marrow-derived Endothelial Progenitor Cells in Advanced Liver Cirrhosis

May 25, 2015 updated by: Clinica Universidad de Navarra, Universidad de Navarra

Pilot Clinical Trial (Phase I/II) to Evaluate Safety and Therapeutic Effects of the Administration of Autologous Bone Marrow-derived EPCs in Patients With Advanced Liver Cirrhosis

Endothelial Progenitor Cells (EPC) represent a small cellular population of bone marrow and peripheral blood cells. EPCs are recruited into injured tissues and play an important role in regeneration and reparation. Experimental and clinical data suggest that EPCs have hepatoprotective activity and could improve liver regeneration during acute and chronic liver injury. The aim of this project is to evaluate the safety and therapeutic effects of autologous bone marrow-derived EPCs, when administered through the hepatic artery of patients with advanced liver cirrhosis.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

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.

Participation Criteria

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). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • Chronic encephalopathy preventing the ability to sign informed consent (it could be done by legal representant of the patient) and/or the ability to follow the study protocol
  • Hepatocellular carcinoma (previous or current)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants with Adverse Events as a Measure of Safety and tolerability
Time Frame: 12 months
The safety of the administration of autologous bone marrow-derived EPC in patients with advanced cirrhosis will be evaluated by anamnesis, physical examination, hematological and biochemical variables and imaging examination.
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes of liver function test as a measure of the effect on liver function
Time Frame: 12 months
Determination of liver function test (aminotransferases,albumin, bilirubin and protrombin time) and calculation of Model for End-Stage Liver Disease (MELD) and Chil-Pugh scores. Differences in these variables compared to baseline will be considered as a measure of the effect on liver function.
12 months
Effect on portal hypertension
Time Frame: 12 months
Changes in Hepatic Venous Pressure Gradient (HVPG) will be used to assess the effect on portal hypertension.
12 months
Effect on complications of liver cirrhosis
Time Frame: 12 months
Ascitis grade, episodes of upper gastrointestinal bleeding as well as of episodes of hepatic encephalopathy will be used as a measure of the effect of the treatment on the complications of liver cirrhosis.
12 months
