Study Endpoints

Primary Endpoints

The efficacy endpoint is achievement of two consecutive > or = 30% decreases from baseline in iPTH levels
Change From Baseline to the Last On-treatment Measurement in Urine Albumin to Creatinine Ratio (UACR) Levels Determined From the First Morning Void (FMV) Urine Collections Comparing Placebo to the Combined Paricalcitol Treatment Groups (1 Mcg and 2 Mcg).
Baseline (within 1 week prior to first treatment) through 24 weeks of treatment

UACR is defined as the ratio: milligram of albumin per gram of creatinine. Baseline UACR was determined as the mean of the 3 UACR measurements from FMV urine collections obtained within 1 week prior to the day of the first dose of study drug. The last on-treatment measurement was the mean of the 3 UACR measurements obtained from FMV urine collections obtained within 1 week of the final week of treatment. The UACR data were log transformed prior to analysis.

Secondary Endpoints

Number of Participants Achieving a 15% or Greater Reduction From Baseline to Last On-treatment Urine Albumin to Creatinine Ratio (UACR) Levels.
Baseline (within 1 week prior to first treatment) through 24 weeks of treatment
Change From Baseline to the Last On-treatment Measurement in Albumin Levels Determined From 24-hour Urine Collection.
Baseline (within 1 week prior to first treatment) through 24 weeks of treatment
Change From Baseline to the Last On-treatment Observation in Intact Parathyroid Hormone (iPTH) Levels.
Baseline (screening period) through 24 weeks of treatment

Frequently asked questions about Zemplar

What is Zemplar used for?

Zemplar is used for kidney disease and diabetic nephropathy. It is being studied in chronic kidney disease patients on hemodialysis or peritoneal dialysis to reduce serum intact parathyroid hormone levels, and in type 2 diabetic nephropathy patients to reduce albuminuria while they are treated with renin-angiotensin system inhibitors.

What does Zemplar target?

Zemplar targets the parathyroid hormone pathway. It is a small molecule developed by Abbott Laboratories for nephrology indications, specifically to reduce serum intact parathyroid hormone levels in chronic kidney disease and to reduce albuminuria in diabetic nephropathy.

Who makes Zemplar?

Zemplar is developed by Abbott Laboratories, traded on the stock exchange under the ticker ABT. The company is conducting clinical trials for the drug in kidney disease and diabetic nephropathy indications.

What phase is Zemplar in?

Zemplar is in Phase 2 clinical development. One Phase 2 trial has been completed, and the drug remains investigational. It is not approved by the FDA, and it is still being studied for its safety and efficacy in kidney disease and diabetic nephropathy.

What clinical trials is Zemplar in?

Zemplar has one completed Phase 2 trial, NCT00421733, which studied the effect of paricalcitol capsules on reducing albuminuria in patients with type 2 diabetic nephropathy. A separate Phase 3 trial, NCT00091975, studied the drug in chronic kidney disease stage 5 patients on dialysis.

Is Zemplar the same as paricalcitol?

Yes, Zemplar is the same as paricalcitol. The clinical trials for Zemplar use paricalcitol capsules as the investigational treatment, and the drug is a small molecule developed by Abbott Laboratories for kidney disease and diabetic nephropathy.
