4 Clinical Trials for Various Conditions
This study is investigating the safety and efficacy of eneboparatide (AZP-3601) in patients with chronic hypoparathyroidism (cHP). During the first 24 weeks of the trial, participants will be randomized to receive eneboparatide or placebo. Study treatment is blinded: patients and doctors will not know which group each patient has been randomized to. All patients will start with a fixed dose of study treatment (eneboparatide or placebo), administered subcutaneously with a pre-filled pen. Study treatment will be individually titrated. After completion of the first 24 weeks, patients will be treated in the open label extension part of the study for 132 weeks. During this phase, all patients (including patients that were in the placebo group) will receive eneboparatide.
The main aim of this study is to find out the long-term safety and effectiveness profile of recombinant human parathyroid hormone (1-84) (rhPTH\[1-84\]) treatment in participants with chronic hypoparathyroidism under conditions of routine clinical practice. Participants will be treated according to their clinic's standard practice determined by the treating doctors. Each participant will fill out a study questionnaire during a routine doctor visit.
This study will evaluate the safety, biological activity, and pharmacokinetics of PTH delivered by subcutaneous injection compared with an infusion pump. We anticipate pump delivery of PTH will be more physiologic because it mimics normal parathyroid gland secretion of PTH. We expect that pump delivery will simultaneously normalize blood and urine calcium, phosphorus and magnesium levels with minimal or no fluctuations throughout the day. Pump therapy will require lower PTH doses and should normalize markers of bone turnover. We expect the improved metabolic control during pump therapy will be especially evident in patients with more severe forms of hypoparathyrodism where there is an unmet need for improved therapy.
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.
