Subject was at least 18 years of age, diagnosed with CKD Stage 5 and undergoing HD or PD.
If female, subject was either not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy), or was of childbearing potential and practicing 1 of the protocol specified methods of birth control, was not breastfeeding and had a negative serum pregnancy test prior to the Treatment Phase.
For those subjects taking phosphate binders prior to the study, the subject had to have been on a stable (type and dose) phosphate binder at least 4 weeks prior to the Pretreatment Phase.
For entry into the Pretreatment Phase, the subject must have had a calcium level \<= 10.5 mg/dL and a CaxP level \<= 65 mg2/dL2.
For entry into the Treatment Phase, the subject must have had iPTH \>= 300 pg/mL (determined by Nichols iPTH assay), a calcium level of 8.0 to 10.5 mg/dL, inclusive, and CaxP \<= 65 mg2/dL2.
Subject voluntarily signed and dated an informed consent, approved by an Institutional Review Board (IRB), after the nature of the study was explained and the subject had the opportunity to ask questions. The informed consent was signed before any study-specific procedures were performed or any medications were withheld.
Additional criteria for HD subjects included the following: the subject was diagnosed with CKD Stage 5 and must have been on maintenance HD 3 times a week (TIW) for at least 2 months prior to the Screening Phase and was expected to remain on HD for the duration of the study.
Additional criteria for PD subjects, included the following: the subject was diagnosed with CKD Stage 5 and must have been on continuous PD (either continuous cycling peritoneal dialysis \[CCPD\], continuous ambulatory peritoneal dialysis \[CAPD\], or a combination of the 2) 7 days per week for at least 2 months prior to the Screening Phase and was expected to remain on this PD regimen for the duration of the study.

Subject received a partial parathyroidectomy within 1 year prior to the Screening Phase.
Subject had acute renal failure within 3 months of the Screening Phase.
Subject had chronic gastrointestinal disease, which in the investigator's opinion, may have resulted in clinically significant gastrointestinal malabsorption.
Subject had taken aluminum-containing phosphate binders for \> 3 weeks in the last 3 months prior to the Screening Phase, or required such medications for \> 3 weeks in the study.
Subject had a current malignancy (with the exception of basal or squamous cell carcinoma of the skin), or clinically significant liver disease, in the opinion of the investigator.
Subject had a history of drug or alcohol abuse within 6 months prior to the Screening Phase.
Subject had evidence of poor compliance with diet, medication or HD/PD that may have interfered, in the investigator's opinion, with adherence to the protocol.
Subject had participated in any investigational drug or device study within 4 weeks prior to the Treatment Phase.
Subject was taking calcitonin, maintenance IV or oral glucocorticoids, cinacalcet, bisphosphonates, vitamin D compounds (other than study drug), or other drugs that may have affected calcium or bone metabolism, other than females on stable estrogen and/or progestin therapy.
Subject was known to be human immunodeficiency virus (HIV) positive.
For any reason, subject was considered by the investigator to be an unsuitable candidate to receive Zemplar.
