Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Patients with Mucopolysaccharidosis, type I (e.g., Hurler syndrome), Maroteaux-Lamy syndrome (MPS VI), Alpha Mannosidosis, or mucolipidosis type II (I-cell disease) who have an HLA-identical or mismatched (at 1 antigen) related marrow, PBSC, or cord blood donor.
  • Patients with Mucopolysaccharidosis, type I, Maroteaux-Lamy syndrome (MPS VI), Alpha Mannosidosis, or mucolipidosis type II (I-cell disease) who have an HLA-identical or HLA-1 antigen mismatched unrelated marrow, PBSC, or HLA-0-2 antigen mismatched umbilical cord blood donor.
  • Patients with MPS type I, Maroteaux Lamy Syndrome (MPS VI), or mucolipidosis type II (I-cell disease) will have a mental developmental index within two standard deviations of the normal mean, as best as can be determined using Bayley scales of infant development or other standardized testing, recognizing that these may be affected by speech and/or hearing impairment.
  • Adequate organ function:
  • Cardiac: ejection fraction >40%; no decompensated congestive heart failure or uncontrolled arrhythmia
  • Renal: serum creatinine <2.0 mg/dl
  • Hepatic: total bilirubin <3x Upper limits of normal transaminases < 5.0 x Upper limits of normal
  • Signed consent.

Who cannot join

  • Presence of major organ dysfunction (see above)
  • Pregnancy
  • Evidence of HIV infection or known HIV positive serology
  • Patients or parents are psychologically incapable of undergoing BMT with associated strict isolation or documented history of medical non-compliance
  • Patients >50 kg may be at risk for having cell doses below the goal of ≥ 10 x 106 CD 34 cells/kg and therefore will not be eligible to receive unrelated PBSCs.

About this study

Official title: Hematopoietic Stem Cell Transplantation for Hurler Syndrome, Maroteaux Lamy Syndrome (MPS VI), and Alpha Mannosidase Deficiency (Mannosidosis)

The purpose of this study is to determine the safety and engraftment of donor hematopoietic cells using this conditioning regimen in patients undergoing a hematopoietic (blood forming) cell transplant for Hurler syndrome, Maroteaux Lamy syndrome, Mannosidosis, or I-cell disease.

Read the detailed description

Prior to transplantation, subjects will receive Busulfan intravenously (IV) via the Hickman line four times daily for 4 days, Cyclophosphamide intravenously via the Hickman line once a day for 4 days, and Anti-Thymocyte Globulin IV via the Hickman line twice daily for three days before the transplant. These three drugs are being given to subjects to help the new marrow "take" and grow.

On the day of transplantation, the donor's hematopoietic cells will be transfused via central venous catheter.

After hematopoietic cell transplant, subjects will then receive two drugs, cyclosporin and either methylprednisolone or Mycophenolate Mofetil (MMF). Cyclosporin and methylprednisolone or MMF are given to help prevent the complication of graft-versus-host disease and to decrease the chance that the new donor cells will be rejected.

What participants receive

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

  • Stem Cell TransplantProcedure or surgery

    Also called Bone Marrow Transplant

    The purpose of hematopoietic cell transplantation is to introduce hematopoietic cells from a normal donor that contains the enzyme able to get rid of the substances that have accumulated in the body of patients with storage diseases. Hematopoietic 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).

  • Busulfan, Cyclophosphamide, ATGDrug

    Also called Busulfex, Cytoxan, Thymoglobulin

    Prior to transplantation, subjects will receive BUSULFAN intravenously (IV) via the Hickman line twice daily for 4 days, CYCLOPHOSPHAMIDE intravenously via the Hickman line once a day for 4 days, and ANTI-THYMOCYTE GLOBULIN IV via the Hickman line twice daily for three days before the transplant. These three drugs are being given to help the new marrow "take" and grow. METHYLPREDNISOLONE will be given as a pre-medication for the ATG.

What is being measured

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

  1. Mean Percentage of Donor Cells in Study Population (Chimerism).

    Donor-derived engraftment determined by restriction fragment length polymorphism (RFLP).

    Measured: at 21 days, 42 days, 60 days, 100 days, 6 months, and 1 year

Secondary outcomes (3)
  1. Number of Patients Surviving on Study

    Number of patients surviving (alive) at specified timepoints.

    Measured: at 100 days, 1 year, and 3 years post transplant

  2. Number of Patients Who Failed Engraftment.

    Toxicity (undesireable effect) of hematologic donor cell engraftment is determined by failure to engraft at Day 42.

    Measured: Day 42 Post Transplant

  3. Number of Patients With Grade III-IV Acute Graft-versus-host Disease (aGVHD).

    Toxicity (undesireable effect) of this stem cell transplant preparative regimen due to acute graft-versus-host disease.

    Measured: Day 100 Post Transplant

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Stem Cell Transplant and Busulfan, Cyclophosphamide, ATG in people with Mucopolysaccharidosis I and Mucopolysaccharidosis VI, 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 8 inclusion and 5 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 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 4 Sep 2009). 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?

Mean Percentage of Donor Cells in Study Population (Chimerism). (time frame: at 21 days, 42 days, 60 days, 100 days, 6 months, and 1 year). 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 28 Dec 2017.
