Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, observational multicenter study to collect blood from patients with mucopolysaccharidosis type IH undergoing laronidase therapy and a stem cell transplant.

Sixteen patients will be enrolled over a 24 month period.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Laronidase therapy and a stem cell transplant

Intervention Type DRUG

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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.
