INTERVENTIONAL
Conditions
Summary
The purpose of this study is to investigate the efficacy and safety of canvuparatide administered as a once-weekly (QW) treatment to adult study participants with hypoparathyroidism (HypoPT).
Eligibility
Inclusion Criteria5
- Is an adult ≥18 years of age.
- Has a documented diagnosis of post-surgical, chronic HypoPT or genetic, idiopathic, or autoimmune HypoPT for at least 12 months prior to screening.
- Intact PTH level below the median value of the normal range
- Minimum requirement for a dose of calcitriol ≥0.5 μg/day, or alfacalcidol ≥1.0 μg/day and (elemental) calcium ≥1000 mg/day for at least 12 weeks prior to screening. In addition, the doses of calcitriol, or alfacalcidol, and calcium should be stable for at least 3 weeks prior to screening.
- Two (2) consecutive measurements of albumin-adjusted serum calcium at least 1 week apart within the range of 7.8 to 9.4 mg/dL (1.95 to 2.35 mmol/L).
Exclusion Criteria5
- Has a known history of pseudohypoparathyroidism
- Clinically significant abnormal hematology, clinical chemistry, or coagulation.
- Any disease that might affect calcium metabolism or calcium-phosphate homeostasis or PTH levels other than HypoPT, such as active endogenous hyperthyroidism;
- Use of therapies affecting the calcium metabolism within 4 weeks prior to randomization
- PTH or PTH-related protein drugs such as PTH(1-84) and PTH(1-34) within 5 weeks prior to screening.
