Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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.

  • Is an adult male or female 18 to 85 years of age, inclusive.
  • In participants 18-25 years of age, has radiological evidence of epiphyseal closure based on bone age X-ray (single posteroanterior X-ray of left wrist and hand) before randomization.
  • Has chronic hypoparathyroidism with onset 12 months or more before screening. The diagnosis of hypoparathyroidism is established based on hypocalcemia in the setting of inappropriately low serum PTH levels.
  • During the Week -3 screening visit, the participant reports by history at least 2 of the following symptoms related to hypoparathyroidism occurring within the 2 weeks before Week -3 visit: muscle cramps, muscle spasms or twitching, tingling, numbness, heaviness in arms or legs, physical fatigue, or slowed or confused thinking (brain fog).
  • The participant must have a Hypoparathyroidism Symptom Diary (HPT-SD) symptom subscale Sum Score of greater than or equal to (\>=) 10 during the 14-day period immediately prior to the baseline (Week 0) visit (Day -14 to Day -1). In addition, the participant must have at least 4 HPT-SD diaries completed in the first 7 day period and at least 4 HPT-SD diaries completed in second 7 day period.
  • Must be treated with active vitamin D (calcitriol or alfacalcidol) alone or in conjunction with calcium supplements for at least 4 months prior to the screening visit.

For participants on thyroid hormone replacement therapy, the thyroid hormone dose must have been stable for at least 4 weeks before screening, and serum TSH level must be within the central laboratory normal range. A serum TSH level below the lower limit of the normal range but not undetectable in participant treated with thyroid hormone may be allowed if there is no anticipated need for a change in thyroid hormone dose during the trial.
  • Has serum 25-hydroxyvitamin D levels \>=50 nmol/L (nanomoles per liter) (20 nanograms per milliliter \[ng/mL\]) and less than (\<) 1.5 times the upper limit of normal (ULN) for the central laboratory normal range.
  • Has estimated glomerular filtration rate (eGFR) greater than (\>) 30 milliliter per minute per 1.73 square meters (ml/min/1.73m\^2).
  • Prior to randomization, is able to perform daily SC self-injections of study medication (or have a designee perform injection) via a multidose injection pen into the thigh.
  • Willing to use oral active vitamin D and calcium supplements provided for the study unless directed to remain on the supplements used prior to enrollment in the current study by the investigator after consultation with the medical monitor.
  • +1 more criteria

You may not qualify if:

  • History of hypoparathyroidism resulting from a known activating mutation in the CaSR gene or impaired responsiveness to PTH (pseudohypoparathyroidism).
  • Any disease that might affect calcium metabolism or calcium-phosphate homeostasis other than hypoparathyroidism, such as poorly controlled hyperthyroidism; Paget disease; type 1 diabetes mellitus or poorly controlled type 2 diabetes mellitus; severe and chronic cardiac, liver (Child-Pugh score \>9) (US FDA, 2003), or renal disease; Cushing syndrome; rheumatoid arthritis; myeloma; active pancreatitis; malnutrition; rickets; recent prolonged immobility; active malignancy (other than low-risk well differentiated thyroid cancer); primary or secondary hyperparathyroidism; or documented parathyroid carcinoma within the previous 5 years, acromegaly, or multiple endocrine neoplasia types 1 and 2.

  • Any disease or condition that, in the opinion of the investigator, may require treatment or make the participant unlikely to fully complete the study or any condition that presents undue risk from the investigational product or procedures. For example, illness that is anticipated to be chronic and not transient.
  • Pregnant or lactating women.
  • Known or suspected intolerance or hypersensitivity to the investigational product, closely-related compounds, or any of the stated ingredients.
