Brief Summary

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

The main purpose of this study is to observe the side effects of VPRIV in participants with type 1 Gaucher disease who are either treatment-naïve (newly diagnosed) or who are currently being treated with enzyme replacement therapy (ERT).

Participants will receive VPRIV intravenously during the treatment period (up to 51 weeks), followed by the end-of-treatment (EOT) visit after 2 weeks.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The drug being tested in this study is called Velaglucerase Alfa (VPRIV). VPRIV will be tested to treat participants with type 1 Gaucher disease. This study will look at the safety, efficacy and pharmacokinetics of VPRIV in the treatment of type 1 Gaucher disease.

The study will enroll approximately 20 participants with Gaucher disease. The study comprises a screening period (Day -21 through Day -4), baseline period (Day -3 through Day 0), treatment period (Week 1 to Week 51), and safety follow-up period. Participants will be assigned to the following drug administration:

• Velaglucerase Alfa (VPRIV)

Participants will receive VPRIV as intravenous (IV) infusion every other week from Week 1 through Week 51 during the Treatment Period. Percentage of participants with at least one serious treatment-emergent adverse event (TEAE) will be evaluated throughout the study.

This multi-center trial will be conducted in China. The overall time to participate in this study is approximately 59 weeks. Participants will make a safety follow-up telephone call or visit to the site after 30 (±7) days of the last infusion of the study drug.

Eligibility Criteria

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

Inclusion Criteria

* Has a documented, confirmed diagnosis of type 1 Gaucher disease based on the following, as determined by the investigator:

1. Decreased glucocerebrosidase (GCB) activity level that is ≤30% of normal or
2. Decreased GCB activity level that is \>30% of normal, but with confirmation of genetic mutation test
* Is at least 2 years of age, inclusive, at screening
* Is naive to treatment for Gaucher disease (Has not received treatment for Gaucher disease \[investigational or approved products\] within the 12 months prior to screening) OR Is receiving or has recently received Imiglucerase ERT (Has received Imiglucerase treatment within the 12 months prior to screening and not within the 14 days prior to screening)
* Has Gaucher disease-related hematological abnormalities, defined as

1. Hemoglobin levels of ≥1 g/dL below the lower limit of normal for their age and gender AND/OR
2. A platelet count of \<90 × 10\^9/L below the lower limit of normal for their age and gender
* Has Gaucher disease-related viscera abnormalities, defined as the following:

* Participant has at least moderate splenomegaly, assessed by palpation (2 to 3 cm below the left costal margin), or by abdominal radiology scan (magnetic resonance imaging \[MRI\] or computed tomography \[CT\] scan, with spleen volume \>5 times normal) AND/OR
* Participant has hepatomegaly, assessed by palpation or by abdominal radiology scan (MRI or CT scan); Participants who have undergone splenectomy must have satisfied these criteria for this study.

Exclusion:

* Has type 2 or 3 Gaucher disease or is suspected of having type 3 Gaucher disease as assessed by the investigator
* Has had a splenectomy or an active, clinically significant spleen infarction within the 12 months prior to screening
* Has received treatment with any investigational drug or device within 30 days prior to screening, or within 5 half-lives of that investigational product, whichever is greater; such treatment during the study will not be permitted
* Is currently receiving red blood cell growth factor (eg, erythropoietin), chronic systemic corticosteroids, or has been on such treatment within the 6 months prior to screening
* Presents with non-Gaucher disease related exacerbated anemia at screening
* Has experienced a severe (grade 3 or higher) infusion-related hypersensitivity reaction (anaphylactic or anaphylactoid reaction) to any ERT (approved or investigational)
