About this study
Official title: The IMPACT SHPT Study: Study to Evaluate the Improved Management of iPTH With Paricalcitol-centered Therapy vs. Cinacalcet Therapy With Low-dose Vitamin D in Hemodialysis Patients With Secondary Hyperparathyroidism
Evaluates the effectiveness of on-label Paricalcitol versus Cinacalcet with Low-Dose Vitamin D.
Read the detailed description
During a 4-week washout period, participants stopped taking cinacalcet or other vitamin D receptor activators (VDRAs). (Participants who were naive to cinacalcet or VDRAs did not have to wash out). At randomization, participants entered a 28-week open-label treatment period, during which they received either cinacalcet or paricalcitol. Participants who were assigned to receive paricalcitol were dosed according to the approved label in their respective geographic regions (i.e., IV at sites in the US and Russia and oral at sites in Europe). Supplemental cinacalcet was administered to participants in the paricalcitol arms who developed hypercalcemia (defined as >= 10.5 mg/dL). The evaluation period was from Weeks 21 to 28.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ParicalcitolDrug
Also called ABT-358, Zemplar
Paricalcitol dosed per label by region (participants were to receive cinacalcet if they developed hypercalcemia)
CinacalcetDrug
Also called Sensipar, Mimpara, Hectorol
On-label oral cinacalcet by region with low dose vitamin D receptor activator (VDRA) (either doxercalciferol at US sites or alfacalcidol at non-US sites)
| Study group | Role | What they receive |
|---|---|---|
| IV Paricalcitol | Active comparator | Participants in the IV stratum received intravenous (IV) paricalcitol and, if hypercalcemia (calcium >= 10.5 mg/dL), received 30 mg of oral cinacalcet. Paricalcitol was dosed at 0.07 mcg/kg with titration every 2 weeks. Receives: Drug: Paricalcitol |

Receives: Drug: Cinacalcet |
| Oral paricalcitol | Active comparator | Participants in the oral stratum received oral paricalcitol and, if hypercalcemia (calcium >= 10.5 mg/dL), received 30 mg of oral cinacalcet. Paricalcitol was dosed at mcg = IPTH/60 3 times weekly (TIW) with titration every 2 weeks. Receives: Drug: Paricalcitol |
| Cinacalcet (at sites with oral paricalcitol) | Active comparator | Participants in the oral stratum received 30 mg of oral cinacalcet daily with a low-dose vitamin D receptor activator (VDRA) (alfacalcidol capsules 0.25 mcg daily). Receives: Drug: Cinacalcet |
What is being measured
The primary outcome is the main question the study is designed to answer.
The Number of Participants Who Achieve a Mean Intact Parathyroid Hormone (iPTH) Value Between 150 to 300 pg/mL During the Evaluation Period (Weeks 21 to 28).
iPTH values obtained during the evaluation period (Weeks 21 to 28) were averaged for each participant with at least 2 iPTH values. Participants whose average iPTH value was between 150 to 300 pg/mL were counted.
Measured: Weeks 21 to 28
Secondary outcomes (5)
Number of Participants Who Achieve at Least 30% Reduction From Baseline in Intact Parathyroid Hormone (iPTH) as Assessed by the Mean iPTH Obtained During the Evaluation Period (Weeks 21 to 28).
iPTH values obtained during the evaluation period (Weeks 21 to 28) were averaged for each participant with both a baseline iPTH value and at least 2 iPTH values. Participants whose average iPTH value showed a 30% reduction from Baseline were counted.
Measured: Weeks 21 to 28
Number of Participants Who Achieve at Least 50% Reduction From Baseline in iPTH as Assessed by the Mean iPTH Obtained During the Evaluation Period (Weeks 21 to 28).
iPTH values obtained during the evaluation period (Weeks 21 to 28) were averaged for each participant with both a baseline iPTH value and at least 2 iPTH values. Participants whose average iPTH value showed a 50% reduction from Baseline were counted.
Measured: Weeks 21 to 28
Analysis of the Number of Participants Who Achieve a Mean iPTH Value Between 150 and 300 pg/mL During the Evaluation Period (Weeks 21 to 28) Using a Cochran-Mantel-Haenszel Test Controlling for IV and Oral Site Randomization Strata
iPTH values obtained during the evaluation period (Weeks 21 to 28) were averaged for each participant with at least 2 iPTH values. Participants whose average iPTH value was between 150 to 300 pg/mL were counted. Data from both the IV and oral strata were analyzed together.
Measured: Weeks 21 to 28
Number of Participants With Hypocalcemia Defined as < 8.4 mg/dL and Based on the Mean of at Least 2 Values Obtained During the Evaluation Period (Weeks 21 to 28)
Calcium values obtained during the evaluation period (Weeks 21 to 28) were averaged for each participant with at least 2 calcium values. Participants whose average calcium value was < 8.4 mg/dL were counted.
Measured: Weeks 21 to 28
Number of Participants With Hypercalcemia Defined as Calcium > 10.5 mg/dL and Based on the Mean of at Least 2 Values Obtained During the Evaluation Period (Weeks 21 to 28)
Calcium values obtained during the evaluation period (Weeks 21 to 28) were averaged for each participant with at least 2 calcium values. Participants whose average calcium value was > 10.5 mg/dL were counted.
Measured: Weeks 21 to 28
