About this study

Official title: Clinical Trial Phase II Multicenter Open Randomized Trial of the Therapeutic Use of Cells Intraportal Infusion of Autologous Bone Marrow Mononuclear as Enhancing Liver Regeneration Prior to Performing Extended Hepatic Resection.

This is a randomized controlled trial in which the safety and feasibility of cell therapy medicinal product shall be measured by comparing the variables of the response after treatment compared to baseline prior to implementation. Secondarily the results obtained are compared with each of the study groups.

Patients will receive concomitant basic pharmacological treatment for maintaining liver function.

All patients will be equally medically treated. The hypothetic test is to propose mononuclear cells from the bone marrow infused in the territory hepatic portal remaining segments (II and III) to be performed while contralateral portal embolization provides progenitor cells hepatic regenerative capacity that would shorten the time of liver regeneration and increase residual volume, facilitating the realization of an extended hepatectomy with greater assurance of maintaining proper residual function and adequate surgical margins.

Read the detailed description

The study population corresponds to patients with hepatic space occupying lesion that require extended hepatic resection and in which the residual liver volume is insufficient to ensure liver function as well as required safety margins after resection.

The study population will consist of a total of 65 patients divided into two groups:

Study group: patients with hepatic space occupying lesion requiring an extended hepatic resection to those who are undergoing preoperative embolization segments portal intraportal affections and application of bone marrow cells.

Control group: patients with hepatic space occupying lesion that require an extended liver resection and who were performed preoperatively embolization portal of the affected segments.

The distribution of cases / controls will be 1/1. Patients in study group before surgery as well as portal embolization of the affected by the injury, will receive the experimental treatment being tested. Autologous bone marrow will be extracted by aspiration of the iliac crest under local anesthesia, and then the mononuclear cells (mo-MNCs) will be separated by density gradient centrifugation on Ficoll by an automatic procedure in the Laboratory for Cell Therapy.

In the control group patients will be held an embolization of liver segments in which are located the lesion.

It is estimated that the inclusion period is approximately 24 months plus the follow-up of each patient twelve months. Thus the total duration of the study will be about thirty-six months from the entry of the first patient until the end of the monitoring period of the last patient included.

The main objective is to evaluate the safety and feasibility of autologous bone marrow mononuclear cells as autologous liver regeneration enhancer, administered intraportal before surgery in patients with liver space occupying lesion that require extended hepatic resection and in which the residual liver volume is insufficient to ensure liver function and safety margins required after the resection.

Secondary objectives:

  • Complications from regenerative therapy and / or study procedures.
  • Increased volume obtained after applying the procedures of liver regeneration after surgery.
  • The percentage of resections that has allowed liver regeneration.
  • The liver functional status after surgery.
  • The resection margins free of tumor.

Evaluation Methods:

Radiological assessment of liver volumes. Analytical evaluation of markers of regeneration.

Being tested
Cell infusion intraportal mononuclear bone marrow autologous and portal embolization of the affected segments.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cell infusion intraportal mononuclear bone marrow autologous and portal embolization of the affected segments. in people with Liver Transplant Rejection, run by Andalusian Initiative for Advanced Therapies - Fundación Pública Andaluza Progreso y Salud at 1 site in Spain.

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 15 inclusion and 14 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: finished, as of the sponsor's last update on 14 Dec 2015. 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 Spain. 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 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.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of adverse events and serious adverse events (time frame: 6 after drug administration of cell therapy.). 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 14 Dec 2015.
