A Phase 2 interventional study of physiological (1.25 mmol/L ) calcium dialysate in Hyperparathyroidism and Hypercalcemia, sponsored by Sun Yat-sen University. Completed at 1 site in China. Open to participants aged 14 Years to 65 Years. Per ClinicalTrials.gov, last updated 2015-05-22.
Sponsored by Sun Yat-sen University · Phase 2, Interventional, and Treatment
A prospective, randomized, controlled multicenter trial to evaluate 1.25 mmol/L (physiological) vs. 1.5 mmol/L calcium dialysate on serum markers of mineral metabolism, secondary hyperparathyroidism and cardiovascular calcification in prevalent haemodialysis patients. And the long term safety of the 1.25 mmol/L calcium dialysate was also considered.
There are two phases of study for each subject. Phase 1 (screening phase). During this phase, each potential subject will be evaluated to determine if he/she is eligible for the study.
Phase 2 (intervention phase). Each subject will be randomly allocated to physiological calcium dialysate (1.25 mmol/L calcium dialysate) group (PCD group), and normal calcium dialysate (1.5 mmol/L calcium dialysate) group (NCD group). The follow-up duration was 36 months.
All patients recruited from these centers who met the inclusion criteria were randomly allocated to physiological calcium dialysate (1.25 mmol/L calcium dialysate) group (PCD group), and normal calcium dialysate (1.5 mmol/L calcium dialysate) group (NCD group). The follow-up duration was 36 months.
Calcium carbonate was mainly used as the phosphate binder. Active vitamin D metabolite, calcitriol (Rocaltrol, Hoffmann La Roche, and Basel, Switzerland) was given as to control the secondary hyperparathyroidism. The doses of these agents were adjusted according to the serum calcium level, serum phosphate level, calcium-phosphorus product and serum iPTH level, which were recommended by the K/DOQI Guidelines 6.3b and 8B. Aluminum hydroxide might be introduced as a phosphate binder for no more than 4 weeks in addition to calcium carbonate and dietary restriction when serum phosphate level could not get a good control (serum P level≥1.78 mmol/L, lasting above 4 weeks). A non- calcium-containing phosphate binder could be administered for 1\~2 weeks in patients with hypercalcaemia during the observation. At the time of the study, non-calcium, non-aluminum based phosphate binders as well as calcium acetate were not available in our country.

Exclusion Criteria:
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.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
