Trial Outcomes & Findings for A Trial Investigating the Safety, Tolerability and Efficacy of TransCon PTH Administered Daily in Adults With Hypoparathyroidism (NCT NCT04701203)

NCT ID: NCT04701203

Last Updated: 2025-03-18

Results Overview

The primary endpoint was a composite endpoint defined as the percentage of subjects who met the following criteria at 26 weeks of blinded treatment: 1) albumin-adjusted serum calcium measured within 4 weeks prior to and on Week 26 visit within the normal range (8.3 to 10.6 mg/dL), and 2) independence from active vitamin D within 4 weeks prior to Week 26 visit (i.e., all daily standing dose of active vitamin D equal to zero AND use of PRN ≤7 days during the 4 weeks), and 3) independence from therapeutic doses of calcium within 4 weeks prior to Week 26 visit (i.e., average daily standing dose of elemental calcium ≤600 mg AND use of PRN doses on ≤7 days during the 4 weeks), and 4) no increase in prescribed study drug within 4 weeks prior to Week 26 visit.

Participant Flow

Overall, 84 subjects were randomized and 82 subjects were dosed. Enrollment of subjects occurred in seven countries: Canada, Denmark, Germany, Italy, Hungary, Norway, and the United States.

A total of 106 subjects were screened and 84 of these met eligibility criteria and were enrolled into the study. Two subjects randomized to TransCon PTH were not treated (1 subject was diagnosed with a recurrence of cancer, and 1 subject withdrew consent). A total of 82 subjects were therefore included in the Intent-to-Treat (ITT) and the Safety analysis populations.
