About this study
Official title: Prophylaxis of the Graft-Versus-Host-Disease in Patients After Allogeneic Stem Cell Transplantation With a Combination of Tacrolimus and Everolimus
The purpose of this pilot study is to provide preliminary data about the efficacy and the safety of the combination of tacrolimus with everolimus in the prophylaxis of the graft-versus-host-disease (GvHD) in patients after allogeneic stem cell transplantation.
Read the detailed description
The allogeneic stem cell transplantation is a successful therapeutic approach in the treatment of a number of hematologic diseases. Nevertheless, it is associated with substantial risks and complications. A major life-threatening complication that occurs in the post transplantation period is the graft versus host disease, especially its severe forms (Grade III and Grade IV). For this reason, a combined immunosuppressive therapy is standard in patients after a stem cell transplantation. In this regard, the combination between cyclosporin A and methotrexate in the prevention of GvHD has been particularly successful. However, the incidence rate of GvHD and consequent mortality are still fairly high. Besides, the therapy itself is accompanied by serious side effects. Therefore, there is a need for a more efficient, less toxic, combined immunosuppressive therapy. The purpose of this pilot study is to test a new combination of immunosuppressives (tacrolimus and everolimus) for the prevention of GvHD after an allogeneic stem cell transplantation. Tacrolimus is a macrolide immunosuppressant that acts as a calcineurin inhibitor, thereby preventing the activation and proliferation of the T-lymphocytes. Everolimus is a semisynthetic macrocyclic lactone that inhibits the activity of a key protein involved in the regulation of the cell cycle, the so called m-TOR protein. Both medicaments act complementary and potently inhibit the proliferation of immune cells. Previous studies have shown that the combination of tacrolimus with everolimus decreases significantly the rejection rate after solid organ transplantation and this combination is generally well tolerated.
This study is designed as a prospective, single-center, non-randomized, open-label non-controlled pilot study. Study related visits are scheduled to take place at regular time intervals and the patients will be followed up to one year after the stem cell transplantation. The study is designed and will be conducted in accordance with the ICH-GCP guidelines and the respective national and international laws.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Tacrolimus and Everolimus in people with Graft vs Host Disease, run by Technische Universität Dresden at 1 site in Germany.
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 3 inclusion and 17 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: stopped early, as of the sponsor's last update on 18 Jun 2009. 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 Germany. 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?
The study was stopped early (reason given: safety reasons). Results are not available in the source record.
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?
Incidence of acute GvHD grade III and IV within the first 100 days after the stem cell transplantation (time frame: first 100 days). 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 NCT00117702, which also lists 21 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 18 Jun 2009.
