Summary

During the first 26 weeks of the trial, participants were randomly assigned to one of two groups: one group received TransCon PTH and one group received placebo. All participants started with study drug at a dose of 18 mcg/day and were individually and progressively titrated to an optimal dose in dose increments of 3 mcg/day. TransCon PTH or placebo were administered as a subcutaneous injection using a pre-filled injection pen. Neither trial participants nor their doctors knew who had been assigned to each group. After the 26 weeks, participants continued in the trial as part of a long-term extension study. During the extension, all participants received TransCon PTH, with the dose adjusted to their individual needs. This was a global trial that was conducted in the United States, Canada, Germany, Denmark, Norway, Italy, and Hungary.
