Official title
A Phase 3, Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial Followed by an Open-Label Extension to Evaluate the Safety and Efficacy of Canvuparatide (MBX 2109) in Adult Patients With Hypoparathyroidism
Overview
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).
Interventions
- Drug Canvuparatide
• Drug per vial: Each DDC contains 1 vial of lyophilized drug product. The reconstituted strengths are 400 μg/mL, 600 μg/mL, 800 μg/mL, 1000 μg/mL, 1200 μg/mL, 1400 μg/mL, and 1600 μg/mL. - Other Placebo
• Drug per vial: Each DDC contains 1 vial of lyophilized drug product. The reconstituted strengths are 400 μg/mL, 600 μg/mL, 800 μg/mL, 1000 μg/mL, 1200 μg/mL, 1400 μg/mL, and 1600 μg/mL.
Primary outcome measures
- To evaluate the effect of pooled weekly doses of canvuparatide on the proportion of responder patients at week 26. [Time frame: 26 Weeks]
Eligibility criteria
Inclusion criteria
- 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 criteria
- 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.
