Change From Baseline in Hypoparathyroidism Symptom Diary (HypoPT-SD) Symptom Subscale Score at Week 26

End point description

The HypoPT-SD is a 13-item patient-reported outcomes instrument that consists of the following items: symptom subscale (items 1-7), anxiety (item 8), sadness or depression (item 9) and impact subscale (items 10-13). For items 1-9, the individual score ranges from None=0 to Very severe=4; for items 10-13, it ranges from Not at all=0 to Very much=2. An item score was computed by taking the average of the daily item response over the 14-day period immediately before the visit. If data were not available for at least 4 out of 7 days during both 7-day periods within the 14-day period, the individual item score was set to missing. The symptom subscale score was computed as the average of symptom items 1-7 scores with more than 3 of the 7 symptom item scores were non-missing. Negative change in scores indicates improvement. A mixed model for repeated measures (MMRM) was used for analysis.

Change From Baseline in Physical Component Summary (PCS) Derived From 36-Item Short Form Health Survey Version 2 (SF-36v2) Scores at Week 26

End point description

The SF-36 is a validated instrument that questions participants about perceived physical and mental health and function. The SF-36 consists of 8 scaled scores (vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health), which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight; the lower the score the more disability. Change in PCS derived from SF-36v2 at Week 26 was reported. A MMRM was used for analysis.

Change From Baseline in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Score at Week 26

End point description

The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) questionnaire contains 13 fatigue-related questions. The responses to the 13 items on the FACIT-Fatigue questionnaire are each measured on a 5-point Likert scale, where 0=Not at all, 1=A little bit, 2=Somewhat, 3=Quite a bit and 4=Very much. Thus, the total score ranges from 0 to 52. High scores represent less fatigue. A MMRM was used for analysis.

The anxiety item score was computed by taking the average of the daily item response over the 14-day period immediately before the visit. If data were not available for at least 4 out of 7 days during both 7-day periods within the 14-day period, the anxiety item score was set to missing. Negative change in scores indicates improvement. MMRM was used for analysis.

End point description

Response was defined as a 30% reduction in HypoPT-SD symptom subscale score from baseline. The HypoPT-SD is a 13-item patient-reported outcomes instrument that consists of the following items: symptom subscale (items 1-7), anxiety (item 8), sadness or depression (item 9) and impact subscale (items 10-13). For items 1-9, the individual score ranges from None=0 to Very severe=4; and for items 10-13, it ranges from Not at all=0 to Very much=2. An item score was computed by taking the average of the daily item response over the 14-day period immediately before the visit. If data were not available for at least 4 out of 7 days during both 7-day periods within the 14-day period, the individual item score was set to missing. The symptom subscale score was computed as the average of symptom items 1-7 scores with more than 3 of the 7 symptom item scores were non-missing.

End point description

The Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) assessment is a 37-item instrument. The perceived cognitive impairment and the impact on quality of life domains were assessed in this study. These 2 domains include 22 items rated on a 5-point scale. The perceived cognitive impairments subscale contains 18 items and each item has a 5-point ordinal response scale (0=Never, 1= About once a week, 2 = Two to three times a week, 3= Nearly every day, 4 = Several times a day). Each item score is calculated as (4 minus item response), and the subscale score is [sum of (4 minus item response)]*18/(number of items answered)]. The perceived cognitive impairment subscale score ranges from 0 to 72, with higher scores indicate better cognitive function. A MMRM was used for analysis.

End point description

WPAI assessed impact of HypoPT on work productivity and daily activities. Concepts that WPAI: Hypoparathyroidism measures include time missed from work and impairment of work and other regular activities due to specific health problem (HypoPT). WPI was calculated based on 4 items including Q2: hours of work missed due to HPT; Q4: actual hours worked; Q5: HPT effect on productivity at work; Q6: HPT effect on daily activities. Scores for 4 subscales were calculated as Percent work time missed due to problem: Q2/(Q2+Q4)*100; Percent impairment while working due to problem: Q5/10*100; Percent overall work impairment due to problem: Q2/(Q2+Q4)+[(1(Q2/(Q2+Q4)))x(Q5/10)]*100; Percent activity impairment due to problem: Q6/10*100. WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes. Change from baseline in questionnaire response was reported. A MMRM was used for analysis. Percent Impairment=PI.
