Clinical Use of PTH(1-84)

Brief summary

The primary objective is: 1\) to describe adherence (and the main factors influencing adherence) to PTH(1-84) treatment when prescribed in a normal clinical setting. The secondary objectives are: 1. to describe the demographics and clinical characteristics of the patients that in a normal clinical setting are started on a treatment regimen with PTH(1-84) 2. to describe (using available data) the long term treatment effectiveness during the 24 months following initiation of PTH(1-84) treatment in a normal clinical setting 3. to monitor safety for 24 months following initiation of PTH(1-84) treatment in a patient in a normal clinical setting.

Design outcomes

MeasureTime frameDescription
Number of Participants Who Discontinued Before 6 Months of Treatment6 monthsA participant was defined as permanently discontinued if treatment with PTH(1-84) was not ongoing at the 6-month time point and at any future time points afterwards.

Secondary

MeasureTime frameDescription
Number of Participants Who Discontinued Before 3, 12, 18, and 24 Months of TreatmentFrom enrollment to 3, 12, 18, and 24 monthsA participant was defined as permanently discontinued if treatment with PTH(1-84) was not ongoing at the 6-month time point and at any future time points afterwards. A participant was defined as temporarily discontinued if treatment with PTH(1-84) was not ongoing at the time point but was then ongoing at a future time point. This was the case when a participant or investigator wanted to pause the treatment for a length of time (e.g. because of an adverse event or interruption). Therefore, a participant was defined as still ongoing during the trial if treatment with PTH(1-84) had not been permanently or temporarily discontinued at that time point. A participant was only defined as missing or unknown if they attended the relevant visit and there was no result or unknown was entered as the result. Results for months 3, 12, 18 and 24 are cumulative data up until that time point.
Duration of Treatment24 monthsDuration of treatment was defined as the last known date that PTH(1-84) was taken minus the first date that PTH(1-84) was taken plus one. In the calculation of duration, no adjustment was made for the prescribed dose frequency or for periods of temporary discontinuation due to adverse drug reactions (ADRs) or temporary patient suspension of treatment.
Treatment Compliance by VisitFrom enrollment to 3, 6, 12, 18, and 24 monthsA participant was defined as compliant if the participant took the treatment as prescribed by the Physician, i.e. complied with the Physician's advice and followed the treatment regimen prescribed. A participant whose dose frequency and treatment length were changed during treatment, e.g. in response to a raised serum calcium level, was regarded as fully compliant if the revised treatment regimen was adhered to. Data on compliance were obtained at each visit and relate to the period since the previous recorded visit.
