Verified August 2016 by Masonic Cancer Center, University of Minnesota
Sponsor:
Information provided by (Responsible Party):
Masonic Cancer Center, University of Minnesota
ClinicalTrials.gov Identifier:
NCT01572636
First received: April 4, 2012
Last updated: August 15, 2016
Last verified: August 2016
  Purpose
This is a standard of care treatment guideline for patients with the diagnosis of mucopolysaccharidosis type IH (MPS I, Hurler syndrome) who are being considered as candidates for first hematopoietic stem cell transplantation (HSCT) according to a University of Minnesota myeloablative HSCT protocol.

Condition Intervention
Mucopolysaccharidosis Type IH MPS I Hurler Syndrome Drug: Laronidase

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: MT2011-21C Laronidase (Aldurazyme TM) Enzyme Replacement Therapy (ERT) With Hematopoietic Stem Cell Transplantation (HSCT) for Hurler Syndrome (MPS IH).

Primary Outcome Measures:
  • Overall Survival [ Time Frame: At 1 Year ]
    Patients alive at 1 year post transplantation.


Secondary Outcome Measures:
  • Incidence of Engraftment [ Time Frame: 1 Year Post Transplant ]
    The incidence of donor engraftment will be estimated by taking the simple proportion of patients achieving donor engraftment over the number of evaluable patients. Donor engraftment will be defined as achieving an absolute neutrophil count ≥ 5x10^8/kg for three consecutive days before day 42 and maintenance of >10% donor chimerism through one year post transplant or death.

  • Incidence of Grade III-IV Acute Graft Versus Host Disease [ Time Frame: Day 100 ]
    Cumulative incidence will be used to estimate grade III-IV acute GvHD, treating death as a competing risk.

  • Proportion of patients in need of ventilator support [ Time Frame: 1 Year ]
    Count of patients using ventilator by 1 year.


Estimated Enrollment: 50
Study Start Date: April 2012
Estimated Study Completion Date: April 2022
Estimated Primary Completion Date: April 2022 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Laronidase use in Hurler Syndrome
Laronidase receiving prior and post transplant
Drug: Laronidase
Administered 0.58 mg/kg/dose intravenously (IV) once a week beginning 12 weeks before planned hematopoietic stem cell transplant (HSCT) and resume same dosing regimen for 8 weeks after HSCT.
Other Name: Aldurazyme

Detailed Description:
Laronidase Enzyme Replacement Therapy will be performed using laronidase once a week for 12 weeks prior to hematopoietic stem cell transplantation and for 8 weeks post-transplant to reduce pulmonary complications.
