Description of intervention(s) / exposure
Subjects will be sequentially allocated to one of 2 dose cohorts:
• Cohort 1 will receive 0.75 mg/kg of PPS
• Cohort 2 will receive 1.5 mg/kg of PPS
All subjects will receive PPS through subcutaneous injection from Day 1 to Week 72 (i.e., 72 weeks on PPS therapy). For Weeks 1 through 12, dosing will be weekly. From Weeks 14 through 72, dosing will be every other week. Intervention will be administered by a suitably qualified member of the study team, either a nurse or a doctor. Adherence to therapy will be recorded by the study team members.

Summary
Brief summary
Complications of MPS I include pain and functional symptoms. The aim of the study is to assess the safety of the investigational product pentosan polysulfate (PPS) in patients with MPSI, and to determine if PPS can successfully alleviate pain and functional symptoms in MPS I patients who have received ERT and/or haemopoietic stem cell transplantation (HSCT).
Up to 10 participants (males and females aged 5 years or greater who meet the inclusion criteria) are expected to be enrolled. This is an open label study, in which participants will be sequentially assigned to receive either 0.75 mg/kg or 1.5 mg/kg of PPS via subcutaneous injection. PPS will be administered weekly for the first 12 weeks and then every second week until the end of the study.
The study will run for 73 weeks from baseline. Following the screening visit, the participants will be required to attend the hospital for assessments out to week 73. Many of the scheduled visits may occur at the patient’s home by a member of the study team. There will be a final study visit involving assessments 5-7 days after the last PPS administration. There will be a final study visit involving assessments 5-7 days after the last PPS administration.
