  Purpose

UX003-CL201 is an open-label Phase 1/2 study to assess the safety, efficacy, and dose of UX003 in MPS 7 subjects via IV administration every other week (QOW) for 36 weeks with up to an additional 36 weeks from the optional continuation period. Up to 5 subjects, 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.

Primary Outcome Measures:
  • Safety and tolerability of UX003 as measured by severity and number of Adverse Events (AEs) [ Time Frame: 36 weeks ] [ Designated as safety issue: Yes ]
  • Efficacy as determined by reduction of total urinary glycosaminoglycan (uGAG) excretion [ Time Frame: 36 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Walking capacity as measured by the 6 Minute Walk Test (6MWT). [ Time Frame: 36 weeks ] [ Designated as safety issue: No ]
  • Stair climbing capacity as measured by the 3 Minute Stair Climb Test [ Time Frame: 36 weeks ] [ Designated as safety issue: No ]
  • Pulmonary function as measured by Forced Vital Capacity(FVC), Forced Expiratory Volume (FEV1) and Maximal Voluntary Ventilation (MVV1) [ Time Frame: 36 weeks ] [ Designated as safety issue: No ]
  • Height and weight growth velocity compared to estimated pretreatment growth rate velocity from medical records (prepubertal pediatric patients only). [ Time Frame: 36 weeks ] [ Designated as safety issue: No ]
  • Shoulder range of motion as measured by goniometry. [ Time Frame: 36 wks ] [ Designated as safety issue: No ]
  • Acceptable dose as determined by total uGAG excretion using a forced dose titration regimen [ Time Frame: 36 weeks ] [ Designated as safety issue: No ]

  Eligibility

Ages Eligible for Study:   5 Years to 30 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Confirmed diagnosis of MPS 7 based on leukocyte or fibroblast glucuronidase enzyme assay or genetic testing confirming diagnosis.
  • Elevated uGAG excretion at a minimum of 2-fold over normal.
  • Between 5 and 30 years of age, inclusive (approximately two 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 become pregnant (self or partner) at any time during the study.
  • Use of any investigational product (drug or device or combination) within 30 days prior to Screening, or requirement for any investigational agent prior to completion of all scheduled study assessments at any time during the study.
  • Has a condition of such severity and acuity, in the opinion of the Investigator, that it warrants immediate surgical intervention or other treatment or may not allow safe study participation.
  • Has a concurrent disease or condition that, in the view of the Investigator, places the subject at high risk of poor treatment compliance or of not completing the study, or would interfere with study participation or affect safety.
