Clinical Trial Summary

Gaucher disease is a rare lysosomal storage disorder caused by deficient activity of the enzyme acid β-glucosidase, causing glucosylceramide to accumulate within macrophages and leading to hepatosplenomegaly, anemia, thrombocytopenia, and bone disease. In the non-neuronpathic form (type 1), disease manifestations are mostly systemic, whereas in the neuronopathic forms, glucosylceramide also accumulates in the central nervous sysem and leads to acute (type 2) or chronic (type 3) neurodegeneration. The purpose of this Phase 1/2 first-in-human study is to initially evaluate the safety and tolerability of two doses of CAN103, and then barring any safety concerns, to evaluate the efficacy and safety of the two doses administered intravenously every other week in treatment-naive subjects with Gaucher disease type 1 or type 3.

Description:

Phase 1: 4 newly treated subjects with Type I Gaucher disease (GD1). Phase 2: 36 newly treated subjects with GD1 or Type III Gaucher disease (GD3)

Eligibility

Inclusion Criteria:

• Subjects have a confirmed clinical, enzymatic, and genetic diagnosis of Gaucher disease (Type 1 or Type 3);
• Phase 1: Subjects with GD1 aged =18 years; Phase 2: Subjects with GD1 or GD3 aged =12 years;
• Subjects have not received enzyme replacement therapy (ERT) or substrate replacement therapy (SRT) within 3 months before screening;
• Subjects have GD-related anemia and one or more of the following disease

manifestations:

Intervention

Drug:
• Low-dose CAN103
Phase 1 is a within-subject dose escalation study to evaluate the safety, tolerability, and pharmacokinetics of two doses of CAN103 in newly treated subjects with GD1. Phase 2 is a randomized, double-blind, parallel group, dose comparison study to evaluate the efficacy and safety of two doses of CAN103 administered intravenously every other week for 37 weeks in newly treated GD1 or GD3 subjects with significant non-neurological clinical manifestations.
• High-dose CAN103
Phase 1 is a within-subject dose escalation study to evaluate the safety, tolerability, and pharmacokinetics of two doses of CAN103 in newly treated subjects with GD1. Phase 2 is a randomized, double-blind, parallel group, dose comparison study to evaluate the efficacy and safety of two doses of CAN103 administered intravenously every other week for 37 weeks in newly treated GD1 or GD3 subjects with significant non-neurological clinical manifestations.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean change in hemoglobin level from Baseline to Week 39 in the high-dose group	Hemoglobin is measured in a central laboratory. An increase from Baseline indicates a therapeutic response.	Baseline to Week 39
Secondary	Mean percent change in platelet count from Baseline to Week 39 in the low-dose and high-dose groups.	Platelet count is measured in a central laboratory. An increase in platelet count indicates a therapeutic response.	Baseline to Week 39
Secondary	Mean percent change in liver volume (multiples of normal, MN) measured by magnetic resonance imaging (MRI) from Baseline to Week 39 in the low-dose and high-dose groups.	Quantitative liver volume is calculated centrally by blinded radiologists. Normal liver volume is defined as 2.5% of body weight. A decrease from Baseline indicates a therapeutic response.	Baseline to Week 39
Secondary	Mean percent change in spleen volume (MN) measured by MRI from Baseline to Week 39 in the low-dose and high-dose groups.	Quantitative spleen volume is calculated centrally by blinded radiologists. Normal spleen volume is defined at 0.2% of body weight. A decrease in spleen volume indicates a therapeutic response.	Baseline to Week 39
Secondary	Mean change in hemoglobin level from Baseline to Week 39 in the low-dose group.	Hemoglobin is measured by a central laboratory. An increase from Baseline indicates a therapeutic response.	Baseline and Week 39
