About this study

Official title: Treatment of Lysosomal and Peroxisomal Inborn Errors of Metabolism by Hematopoietic Cell Transplantation

The primary objective of this clinical trial is to evaluate the ability to achieve and sustain donor engraftment in patients with lysosomal and peroxisomal inborn errors of metabolism undergoing hematopoietic stem cell transplantation (HCT).

Read the detailed description

This has been an ongoing area of interest by our group at the Univ. of Minnesota, but this is a new protocol to take the place of several older protocols. While survival has been very good on the prior protocols over the past decade, incomplete engraftment has remained somewhat problematic. Therefore, we have modified the preparative regimen somewhat to increase engraftment by replacing anti-thymocyte globulin (ATG) with Campath-1H, a drug that is more immune suppressive. In addition, we have modified the supportive care regimen. Based on this, we will monitor levels of an anti-oxidant therapy (N-acetylcysteine) and biomarkers of inflammation and oxidative stress for the families that consent to these research studies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Stem Cell TransplantationProcedure or surgery

    Also called Bone Marrow Transplant, cord blood transplant

    The purpose of hematopoietic stem cell transplantation is to introduce blood producing cells from a normal donor. These cells can either provide what is missing in the body to the other cells, or can change the body's immune response to the substances that have accumulated in the body. These normal hematopoietic stem cells can come from bone marrow, peripheral blood (i.e., the blood circulating in our body's blood vessels) or umbilical cord blood (i.e., blood taken from the umbilical cord after a baby is born and umbilical cord is cut). The new donor cells repopulate the blood and bone marrow system and enter the organs of the body, including the brain. Wherever these cells go, they will produce the needed enzyme.

What is being measured

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

  1. Number of Patients Achieving Engraftment

    Rate of successful engraftment - patients who achieved and sustained donor engraftment; donor chimerism by day 100 of at least 90% after undergoing hematopoietic stem cell transplantation.

    Measured: Day 100

Secondary outcomes (1)
  1. Overall Survival

    Number of patients alive at timepoints.

    Measured: Day 100, 1 Year, 3 Years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Stem Cell Transplantation, Cyclophosphamide and Campath-1H in people with Hurler's Syndrome and Maroteaux-Lamy Syndrome, run by Masonic Cancer Center, University of Minnesota 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 16 inclusion and 9 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 28 Dec 2017. 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 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?

Yes. Results are posted in the registry (first posted 13 Jul 2011). 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?

Number of Patients Achieving Engraftment (time frame: Day 100). 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 NCT00668564, which also lists 1 linked publication.

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 28 Dec 2017.
