研究人群
Study entry is open to pediatric patients regardless of gender or ethnic background. While there will be every effort to seek out and include females and minority patients, the patient population is dependent upon the MPS-IH populations at the University of Minnesota.
描述
Inclusion Criteria:
-
Between 0 to 3 years of age
- Meet protocol specific eligibility criteria for allogeneic HCT for MPS IH
- Planning to receive laronidase both pre and post-transplant in an inpatient setting as part of standard-of-care treatment. Virtually all patients with MPSIH being considered for transplantation at the University of Minnesota are already receiving enzyme infusions, and it is standard practice to continue to give enzyme infusions to 8 weeks post-transplant. Therefore, participation will not modify the treatment course.
Exclusion Criteria:
- Patient's parent/ legal guardians are unable to provide informed consent.

Collect blood from patients with MPS-IH) undergoing laronidase therapy and stem cell transplant.
The primary aim is to characterize the PK of IV laronidase in individuals with MPS IH and identify patient specific covariates that impact drug exposure. The secondary aim is to identify key differences pre-and post-HCT leading to variability in PK parameters for patients receiving IV laronidase therapy for the treatment of MPS-IH. |
To identify key differences leading to variability in PK parameters for patients receiving IV laronidase therapy for the treatment of MPS-IH. There will be 12 samples per patient (6 pre-transplant and 6-post-transplant). Laronidase will be administered IV per protocol using standard dosing (0.58 mg/kg intravenously on a weekly basis), and six (n=6) blood samples will be collected over 24 hours for the determination of mononuclear cell lysates and plasma laronidase concentrations for a total of 18mL. The second PK monitoring will be obtained using the same PK design but following complete or near-completedonor derived myeloid engraftment which is evaluated at different time pointspost-HCT (day 30, day 42, day 60). The standard is to continue ERT through 8 weeks post-transplant. |
