Trial ID Title Status Sponsor Phase Start Date Summary
NCT00000400 ↗ Alendronate and/or Parathyroid Hormone for Osteoporosis Completed National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Phase 2 1999-08-01 This study looks at the effects of two medications, alendronate and parathyroid hormone, on bone mass and on bone formation and bone breakdown in women with osteoporosis. We will randomly select postmenopausal women who have osteoporosis to receive laboratory-produced human parathyroid hormone (hPTH), or alendronate, or both for 2.5 years. Study participants will return to the study center periodically to have their bone mass measured and to give blood and urine samples for tests of bone formation and breakdown and for other laboratory tests. Those who complete the study are eligible for one or two 12 month extension studies.
NCT00000400 ↗ Alendronate and/or Parathyroid Hormone for Osteoporosis Completed Massachusetts General Hospital Phase 2 1999-08-01 This study looks at the effects of two medications, alendronate and parathyroid hormone, on bone mass and on bone formation and bone breakdown in women with osteoporosis. We will randomly select postmenopausal women who have osteoporosis to receive laboratory-produced human parathyroid hormone (hPTH), or alendronate, or both for 2.5 years.

NCT00000427 ↗ Effects of Parathyroid Hormone in Men With Osteoporosis Completed National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Phase 3 1999-09-01 Alendronate is a drug that blocks or reduces bone loss, while parathyroid hormone (PTH) stimulates the formation of new bone. The purpose of this study is to compare the bone-building effects of PTH alone, alendronate alone, and both PTH and alendronate in men with osteoporosis over a two-and-a-half year period.
NCT00000427 ↗ Effects of Parathyroid Hormone in Men With Osteoporosis Completed Massachusetts General Hospital Phase 3 1999-09-01 Alendronate is a drug that blocks or reduces bone loss, while parathyroid hormone (PTH) stimulates the formation of new bone. The purpose of this study is to compare the bone-building effects of PTH alone, alendronate alone, and both PTH and alendronate in men with osteoporosis over a two-and-a-half year period.
NCT00000543 ↗ Oral Calcium in Pregnant Women With Hypertension Completed National Heart, Lung, and Blood Institute (NHLBI) Phase 2 1993-08-01 To determine of providing calcium supplementation to women with pre-existing hypertension reduces the level of blood pressure, requirement for antihypertensive drugs, and incidence of pre-eclampsia.
NCT00001277 ↗ Studies of Elevated Parathyroid Activity Completed National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) 1993-12-15 Patients whose parathyroid activity is elevated above normal are referred to as having hyperparathyroidism. This study will help researchers better understand the causes of hyperthyroidism and to evaluate and improve methods for diagnosis and treatment. In this study, patients diagnosed with or suspected of having hyperparathyroidism will be selected to participate. In addition, patients with related conditions such as parathyroid tumors, will also be selected. Subjects will be asked to provide blood and urine for testing to confirm their condition. They will then be surgically treated by removal of the parathyroid gland(s) (parathyroidectomy). Subjects with parathyroid tumors will undergo several diagnostic tests to determine the exact location of the tumor as well as the tumor's activity. The tests may include; ultrasounds, nuclear scanning, CT scans, MRI, and specialized blood testing. Sometimes parathyroidectomy leads to hypoparathyroidism. Options for treating the patients after the surgical procedure will also be addressed. Calcium and Vitamin D supplements are typically the mainstay of post parathyroidectomy therapy. Other potential treatments include transplanting the parathyroid gland(s) to other areas of the body.
NCT00001304 ↗ Treatment of Hypoparathyroidism With Synthetic Human Parathyroid Hormone 1-34 Completed Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Phase 2 1991-10-01 This study has been important in establishing synthetic human parathyroid hormone 1-34 (PTH) as a beneficial treatment for hypoparathyroidism, superior to conventional therapy with calcium and calcitriol. Providing synthetic human parathyroid hormone 1-34 (PTH) to patients who are unresponsive to conventional therapy has enabled severe cases of hypoparathyroidism to be managed effectively with the investigational drug, PTH. The primary goals of this study are to (1) provide long-term PTH therapy to patients who do not respond to conventional therapy; (2) understand the long-term effect of therapeutic PTH replacement on kidney function and bone mineral density; (3) study and track linear growth and bone accrual in children with hypoparathyroidism. (4) determine if subjects reach a normal level of peak bone mass and if the timing of this is comparable to normal age-matched healthy controls.

Parathyroid hormone Market Analysis and Financial Projection

Last updated: February 8, 2026

What Is the Current Status of Clinical Trials for Parathyroid Hormone?

Parathyroid hormone (PTH), primarily represented by formulations like teriparatide (Forteo) and abaloparatide (Tymlos), continues to undergo clinical assessments primarily for osteoporosis and other bone-related disorders.

Key Clinical Data:

  • Teriparatide (Forteo): Approved by FDA in 2002. As of 2023, over 200 clinical trials registered, with approximately 40 actively recruiting or ongoing. The focus has shifted toward combination therapies, different dosing schedules, and other indications such as hypoparathyroidism.

  • Abaloparatide (Tymlos): Approved in 2017; around 100 trials registered, with 20 ongoing or recruiting. Current focus includes fracture risk reduction and potential extended use beyond 24 months.

  • Novel PTH Analogues: Several companies explore PTH mimetics with altered pharmacokinetics to enhance efficacy and safety profiles.

Regulatory Activity:

  • Both drugs face ongoing post-marketing studies addressing long-term safety, especially concerning osteosarcoma risk, a concern originating from rodent studies.

How Does the Market for Parathyroid Hormone Drugs Look Today?

The PTH market focuses primarily on osteoporosis treatment, particularly among postmenopausal women and patients on glucocorticoids.
