Study of Aldurazyme® Replacement Therapy in Patients With Mucopolysaccharidosis I (MPS I) Disease

Japan3 participantsStarted 2005-12

Plain-language summary

This is a multi-center, open label, study conducted to evaluate the safety of laronidase administered by intravenous drip infusion in Japanese patients with MPS I disease. Following baseline evaluation, patients will receive weekly infusions of JC0498 at an intravenous dose of 100 units/kg. Patient safety will be monitored continuously throughout the trial. In addition, the effects of JC0498 treatment in this patient population will be assessed by periodically evaluating aspects of MPS I disease in patients at scheduled intervals over the duration of the trial. Since patients may be eligible for the trial if they have received JC0498, a portion of the data may be captured retrospectively and recorded onto the case report forms (CRFs). This study represents the first good clinical practice (GCP) effort to characterize MPS I in the Japanese population and evaluate the effects of JC0498 on disease manifestations.

Inclusion Criteria: * Written informed consent/assent of the patient or written informed consent of the parent(s) or the legal guardian(s), depending on the age of the patient, is required prior to any protocol-related procedures being performed; this includes information regarding hematopoietic stem cell transplantation (HSCT) in order to assure that the guardian(s) is fully informed regarding the risks and benefits of this alternative treatment for patients eligible for the trial and who have severe manifestations of MPS I with neurodegeneration. * Have a clinical diagnosis of MPS, confirmed by measurable clinical signs and symptoms of MPS I. * Have confirmed iduronidase deficiency with a leukocyte alpha-L-iduronidase enzyme activity level of less than 10.0% of the lower limit of the normal range of the measuring laboratory (SRL) Exclusion Criteria: * The patient is under consideration for or has previously undergone hematopoietic stem cell transplantation. * The patient has acute hydrocephalus at the time of enrollment. * The patient has a clinically significant organic disease (with the exception of symptoms relating to MPS I) including: cardiovascular, hepatic, pulmonary, neurologic, or renal disease, other serious intercurrent illness, or extenuating circumstances that, in the opinion of the Investigator, would preclude participation in the trial or potentially decrease survival. * The patient has received any investigational product within 30 days prior to trial enr…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
