NCT03071263

Brief Summary

The purpose of this study is to determine if patiromer treatment in chronic kidney disease (CKD) subjects receiving spironolactone for the treatment of resistant hypertension will result in more persistent use of spironolactone through prevention of hyperkalemia and lead to improved blood pressure control compared with treatment with spironolactone alone (placebo).

Outcome Measures

Primary Outcomes (1)

  • Number of Participants Remaining on Spironolactone at Week 12

    The proportion of subjects remaining on spironolactone at Week 12 will be compared between treatment groups (spironolactone/patiromer versus spironolactone/placebo). Subjects who discontinued from the study early or discontinued study spironolactone prior to Week 12, for any reason, were considered as not having remained on spironolactone until Week 12.

    At week 12

Secondary Outcomes (1)

  • Change in AOBP SBP From Baseline to Week 12 or Last Available AOBP SBP Prior to Addition of Any New BP Medications or Increase From Any Baseline BP Medications

    From baseline to Week 12

Other Outcomes (7)

  • Change in AOBP SBP From Baseline to Week 12 Regardless of Increase in Antihypertensives

    From baseline to Week 12

  • Central Serum Potassium Change From Baseline to Week 12 by Baseline Serum Potassium Category

    From baseline to Week 12

  • Participants With Central Serum Potassium <5.5 mEq/L Over Time

    From baseline to Week 12

  • +4 more other outcomes
