A Study of Extended Use of Recombinant Human Parathyroid Hormone (rhPTH(1-84)) in Hypoparathyroidism

Completed · Phase 4

Conditions studied: Chronic Hypoparathyroidism, Hypoparathyroidism

In brief

Chronic hypoparathyroidism is a life-long and irreversible disease for which the chronic administration of rhPTH(1-84) is a potential treatment option. The group of participants in the AAAE0544 core study has been taking rhPTH(1-84) for the treatment of hypoparathyroidism for up to 11 years. This study is designed to extend this experience and gain knowledge about how safe and effective rhPTH(1-84) is in participants with hypoparathyroidism over a long-term duration.

Who can join

Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Participants that are currently or previously enrolled in the core study (AAAE0544 [NCT01199614]) and have maintained uninterrupted therapy with recombinant human parathyroid hormone (rhPTH(1-84)) (transient interruptions of up to 1 month continuously off treatment may be allowed).
• Signed and dated informed consent form (ICF).
• Adult men and women 18 to 85 years of age.
• History of hypoparathyroidism for at least 12 months prior to rhPTH(1-84) treatment, defined by the requirement for supplemental calcium and/or active vitamin D to maintain serum calcium along with an undetectable or insufficient Parathyroid hormone (PTH) concentration.
• Able to perform daily subcutaneous (SC) self-injections of study medication (or have designee perform injection).
• Willingness and ability to understand and comply with the protocol. Women must agree to pregnancy testing and acceptable methods of contraception, as detailed in the protocol.

You may not qualify if…

• The participant is treated or has been treated with any investigational drug, aside from rhPTH(1-84), within 30 days of consent.
• As assessed by the investigator, the participant has any safety or medical issues that contraindicate participation in the study.
• The participant and/or the participant's parent(s) or legally-authorized representative(s) are unable to understand the nature, scope, and possible consequences of the study.
• The participant is unable to comply with the protocol, example, uncooperative with protocol schedule, refusal to agree to all of the study procedures, inability to return for evaluations, or is otherwise unlikely to complete the study, as determined by the investigator or the medical monitor.
• The participant is pregnant or lactating.
• Participants who are at increased baseline risk for osteosarcoma such as participant with Paget's disease of bone or unexplained new elevations of alkaline phosphatase, participants with hereditary disorders predisposing to osteosarcoma or participants with a prior history of external beam or implant radiation therapy involving the skeleton.
