About this study

Official title: A Phase I/II Study of Llme Treated Non-Myeloablative Allogeneic Hematopoietic Stem Cell Transplantation for Patients With Hematological Malignancies

The purpose of this research study is to determine if an experimental agent, LLME can decrease the incidence and severity of Graft-Versus-Host-Disease (GVHD) following blood (hematopoietic) stem cell transplantation

Read the detailed description

We believe that the risks of allogeneic transplant can be drastically reduced if the following criteria can be met: (1) consistent engraftment, (2) little or no GVHD with the ability to rapidly withdraw immune suppression, (3) rapid recovery of CD4 counts to levels greater than 200 cells/micro liter. Our prior (ongoing) trial attempts to address how LLME treated T cells given as donor lymphocyte infusion (DLI) can address points 2 and 3 above. The current study addresses how treatment of the CD34- fraction of the graft attempts to address points 1 and 2 (and to a lesser extent point 3) above. We believe that if these points can be consistently achieved that the mortality of allogeneic HSCT may be reduced to levels more akin to those of autologous HSCT. We propose to test the hypothesis that LLME-treated T cells will be safe with regard to reducing GVHD or other infusion related toxicities and that their administration as part of the transplant will facilitate engraftment. We believe that this approach will ultimately be an important step in a variety of transplant settings ranging from matched siblings to haplodisparate donors.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety of CD34+ Stem Cell Infusions Followed by LLME as Measured by 100-Day Mortality

    Determine the safety of CD34+ stem cell infusions followed by the LLME treated CD34- fraction. This includes monitoring the patients for any side effects associated with the LLME treated cell infusion or any other unexpected adverse events.

    This regimen will be gauged as to its safety using 100 day mortality as the measured endpoint. Deaths from all causes will be included.

    Measured: Through 100 days post-transplant or death

Secondary outcomes (4)
  1. Rate of Engraftment of Non-Myeloablative Transplants

    Determine the engraftment rate of non-myeloablative transplants using CD34+ stem cells and LLME treated CD34- products.

    Measured: Through 30 days post-transplant

  2. Incidence of Grade II-IV Acute Graft-Versus-Host-Disease (GVHD)

    Determine the incidence of grade II-IV acute GVHD after administration of grafts when combined with Cyclosporine/Mycophenolate Mofetil for GVHD prophylaxis. GVHD assessments occur daily as an in patient and at each out patient visit.

    Measured: Through 24 months post-treatment

  3. Rate of Serious Infectious Complications

    Determine the rate of serious infectious complications. A serious infection will be defined as any requiring hospitalization or parenteral therapy.

    CD4 counts will be measured monthly for the first 3 months after transplant.

    Measured: Through 3 months post-transplant

  4. Number of Patients Who Achieve a CD4 Count > 200/Micro-liters

    Determine the number of patients who achieve a CD4 count > 200/micro-liters by 60 days after transplant.

    Measured: Through 60 Days Post Transplant

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing L-leucyl-L-leucine Methyl Ester (LLME), Fludarabine and Cytarabine in people with Hematologic Malignancies, run by Sidney Kimmel Comprehensive Cancer Center at Thomas Jefferson University at 1 site in United States.

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 12 inclusion and 1 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 29 Nov 2016. 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 United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Yes. Results are posted in the registry (first posted 10 Dec 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Safety of CD34+ Stem Cell Infusions Followed by LLME as Measured by 100-Day Mortality (time frame: Through 100 days post-transplant or death). 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 29 Nov 2016.
