Observational Program of Zemplar in Patients With End Stage Chronic Kidney Disease and Parathyroid Disorder on Hemodialysis in the Russian Federation

AbbVie (prior sponsor, Abbott)86 enrolled

Overview

Eighty-six eligible participants with secondary hyperparathyroidism will be enrolled at thirteen sites in Russia. Planned therapy will be six months. Participants with Stage 5 Chronic Kidney Disease and with hyperparathyroidism on hemodialysis will be included into the study. Ability of Zemplar, (paricalcitol) to lower intact Parathyroid Hormone level will be assessed during the study.

Eighty-six eligible participants with secondary hyperparathyroidism will be enrolled at thirteen sites in Russia. Study drug will be administered per local prescribing guidelines. Planned therapy is six months. Intact Parathyroid Hormone will be measured at the Screening visit. All participants who meet the inclusion criteria and fail to meet the exclusion criteria will be included in the study. Adverse events will be monitored throughout the observation period (and up to 30 days after the last dose of Zemplar). Ability of Zemplar to lower intact Parathyroid Hormone level will be assessed throughout the study. Proportion of participants with the level of intact Parathyroid Hormone 150 - 300 pg/mL was stated as primary endpoint. Calcium and Phosphorus elevation will be also measured throughout the study. The selected population is representative in relation to those who will take Zemplar in routine practice. Participants with contraindications to Zemplar therapy (as per the local label) will not be included in the study.

Outcomes

Primary Outcomes

The Percentage of Participants Who Reached a Target Level of Intact Parathyroid Hormone (iPTH) (150-300 pg/mL) Post-baseline at Least Once During the Study

The percentage of participants who had a post-baseline intact parathyroid hormone (iPTH) level in the range of 150 to 300 pg/mL at least once during the study was recorded.

Time frame: 6 months

Secondary Outcomes

Percentage of Participants Who Reached the Kidney Disease Improving Global Outcomes Target Level of Intact Parathyroid Hormone (iPTH) at Least Once During the Study

The percentage of participants who reached the Kidney Disease Improving Global Outcomes target level of intact parathyroid hormone (iPTH) (defined as achievement of iPTH level 2 to 9 times the upper limit of normal) at least once during the study was recorded.

Time frame: 6 months

Percentage of Participants Who Reached the Kidney Disease Improving Global Outcomes Target Level of Intact Parathyroid Hormone (iPTH) at Each Visit During the Study

The percentage of participants who reached the Kidney Disease Improving Global Outcomes target level of intact parathyroid hormone (iPTH) (defined as the achievement of iPTH level 2 to 9 times the upper limit of normal) at each visit during the study was recorded.

Time frame: 6 months

Percentage of Participants Who Developed Elevated Calcium (Ca) x Phosphate (P) (> 75 mg˄2/dL˄2) Levels at Least Once Post-baseline During the Study

The percentage of participants who developed elevated calcium (Ca) x phosphate (P) (\> 75 mg˄2/dL˄2) levels at least once post-baseline during the study was recorded.

Time frame: 6 months

Percentage of Participants Who Developed Elevated Calcium (Ca) x Phosphate (P) (> 75 mg˄2/dL˄2) Levels at Each Visit Post-baseline During the Study

The percentage of participants who developed elevated calcium (Ca) x phosphate (P) (\> 75 mg˄2/dL˄2) levels at each visit post-baseline during the study was recorded.
