A Phase 2 interventional study of ASP7991 and Cinacalcet in Secondary Hyperparathyroidism, sponsored by Astellas Pharma Inc. Completed at 6 sites in Japan. Open to participants aged 20 Years to 79 Years. Per ClinicalTrials.gov, last updated 2024-11-06.
Sponsored by Astellas Pharma Inc · Phase 2, Interventional, and Treatment
To examine efficacy and safety after 12-week administration of ASP7991 in secondary hyperparathyroidism patients undergoing hemodialysis
This study is a multicenter, double-blind, randomized, Cinacalcet hydrochloride-controlled, parallel-group, dose-ascending study. Subjects judged to be eligible will be registered and randomized into either ASP7991 group (receiving ASP7991 and cinacalcet-placebo) or Cinacalcet group (receiving cinacalcet and ASP7991-placebo), and will receive 12-week (84 days) administration of study drug from first dialysis day in a week (treatment period), in a double-blind manner. The dose of the study drugs will be increased every 3 weeks in dose-ascending manner.
Follow-up assessment will be performed before starting first dialysis in a week, 1 week (7 days) after the completion of the treatment period.
188 studies on the registry are indexed under Hyperparathyroidism, Secondary; 15 are open to participants now.
This study's enrollment of 62 is close to the median of 62 across 146 interventional studies indexed under Hyperparathyroidism, Secondary.

Exclusion Criteria:
investigator / subinvestigator
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
