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: 2026-02-09

Results Overview

The primary endpoint was a multi-component endpoint that included the percentage of participants 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.

n=80 participants at risk
Participants who completed the 26-week double blind treatment period in placebo and TransCon PTH groups, continued into the open-label extension period and received treatment with TransCon PTH up to Week 182. This period refers to total period of exposure to TransCon PTH. For participants randomized to TransCon PTH at enrollment, the "TransCon PTH Period" was the time from first dose of blinded TransCon PTH until final analysis in OLE period. The TransCon PTH Period for participants randomized to placebo at enrollment was the time from first exposure to TransCon PTH at the time of cross-over from placebo, until final analysis in the OLE period.

TransCon PTH at a starting dose of 18 mcg delivered once daily by subcutaneous injection and titrated to an optimal dose during the blinded period TransCon PTH: TransCon PTH drug product is supplied as a solution with a concentration of 0.3 mg PTH(1-34)/mL in a single-patient-use prefilled pen intended for subcutaneous injection.
Double Blind: Placebo
n=21 participants at risk
Placebo for TransCon PTH delivered once daily by subcutaneous injection during the blinded period Placebo: Placebo is supplied as a solution containing the formulation buffer for TransCon PTH in a single-patient-use prefilled pen intended for subcutaneous injection.
Total TransCon PTH Period
n=80 participants at risk
Participants who completed the 26-week double blind treatment period in placebo and TransCon PTH groups, continued into the open-label extension period and received treatment with TransCon PTH up to Week 182. This period refers to total period of exposure to TransCon PTH. For participants randomized to TransCon PTH at enrollment, the "TransCon PTH Period" was the time from first dose of blinded TransCon PTH until final analysis in OLE period. The TransCon PTH Period for participants randomized to placebo at enrollment was the time from first exposure to TransCon PTH at the time of cross-over from placebo, until final analysis in the OLE period.
