An Open-Label Phase 1/2 Study to Assess the Safety, Efficacy and Dose of Study Drug UX003 Recombinant Human Beta-glucuronidase (rhGUS) Enzyme Replacement Therapy in Patients With Mucopolysaccharidosis Type 7 (MPS 7)
United Kingdom3 participantsStarted 2013-11
Plain-language summary
UX003-CL201 is an open-label Phase 1/2 study to assess the safety, efficacy, and dose of UX003 in MPS 7 patients via intravenous (IV) administration every other week (QOW) for 36 weeks with up to an additional 36 weeks from the optional continuation period. Up to 5 participants, who are between 5 and 30 years of age inclusive, will be enrolled and treated with UX003.
The initial 12-week treatment period will be followed by a 24-week forced dose titration period to assess the optimal dose. Participants who complete both the initial treatment and forced dose titration periods will continue treatment in a 36- week continuation period.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Confirmed diagnosis of MPS 7 based on leukocyte or fibroblast glucuronidase enzyme assay or genetic testing confirming diagnosis.
* Elevated urinary glycosaminoglycan (uGAG) excretion at a minimum of 2-fold over normal.
* Between 5 and 30 years of age, inclusive (approximately 2 subjects between the ages of 20-30 years).
* Willing and able to provide written, signed informed consent, or in the case of subjects under the age of 18 (or 16 years, depending on the region), provide written assent (if required) and written informed consent by a legally authorized representative after the nature of the study has been explained, and prior to any research-related procedures.
* Sexually active subjects must be willing to use an acceptable method of contraception while participating in the study.
* Females of childbearing potential must have a negative pregnancy test at Screening and be willing to have additional pregnancy tests during the study. Females considered not of childbearing potential include those who have had tubal ligation at least one year prior to Screening, or who have had total hysterectomy.
Exclusion Criteria:
* Has undergone a successful bone marrow or stem cell transplant or has any degree of detectable chimaerism with donor cells.
* Any known hypersensitivity to rhGUS or its excipients that, in the judgment of the Investigator, places the subject at increased risk for adverse effects.
* Pregnant or breastfeeding at Screening or planning to b…
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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.

Percentage Change From Baseline in Urinary Glycosaminoglycan (uGAG) Dermatan Sulfate
Timeframe: Baseline, Week 14, Week 22, Week 30, Week 38, Week 72, and end of study (up to Week 132)
2
Percentage Change From Baseline in uGAG Chondroitin Sulfate
Timeframe: Baseline, Week 14, Week 22, Week 30, Week 38, Week 72, and end of study (up to Week 132)

Number of Participants With Any ≥ 50% Decrease in uGAG
Timeframe: up to Week 132
4
Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), Deaths, and Study/Treatment Discontinuations
Timeframe: Up to 242 weeks + 30 days. SAEs were recorded beginning at the time the subject signed the informed consent form through 30 days following the last study visit. Non-serious AEs were recorded from the time of informed consent through the last study visit.
