A Study to Learn if Recombinant Human Parathyroid Hormone [rhPTH(1-84)] Can Improve Symptoms and Metabolic Control in Adults With Hypoparathyroidism (BALANCE)

Shire93 enrolled

Overview

Recombinant human parathyroid hormone, also known as if rhPTH(1-84), is a medicine to treat people with Hypothyroidism. The main aim of this study is to learn if rhPTH(1-84) can improve symptoms in adults with hypoparathyroidism. In this study, participants will receive 1 of 2 treatments: rhPTH(1-84) or a placebo. A placebo looks like the medicine being studied but does not have medicine in it. In this study, the placebo will be a standard treatment which is either active Vitamin D, or active Vitamin D with calcium. Active Vitamin D is a form of vitamin D that has a faster effect on the body. These treatments will be given as a daily injection just under the skin. Participants will not know which treatment they received, nor will their study doctors. This is to help make sure the results are more reliable. All participants will also take active vitamin D and calcium supplements during treatment. Participants will record their symptoms in a tool called the hypoparathyroidism symptom diary. This tool is used to assess symptoms and their impact and will give an overall score for each participant. The study doctors will also check for side effects from the study treatments. After treatment, researchers will check if there is any difference in the diary scores between the 2 treatment groups. A difference in score means there is a difference in symptoms and their impact. From this, researchers will learn if symptoms have improved for participants treated with rhPTH(1-84) compared with those treated with placebo.

24 SEPTEMBER 2020: The temporary enrollment stop of new patients into this study due to the COVID-19 pandemic has been lifted in one or more countries, and the study is now again enrolling new patients. However, some countries/sites may still have paused the enrollment of new patients due to the pandemic. 20 APRIL 2020: Enrollment of new patients into this study has been paused due to the COVID-19 situation. The duration of this pause is dependent on the leveling and control of the COVID-19 pandemic.

Outcomes

Primary Outcomes

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

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.

Secondary Outcomes

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

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.
