Study Details

Study Description

Brief Summary

This study determined the optimal starting dose of patiromer in treating hyperkalemia in participants with hypertension and diabetic nephropathy who were already receiving ACEI and/or ARB drugs, with or without spironolactone. This study also evaluated the efficacy and safety of patiromer and the long term use of patiromer.

Detailed Description

RLY5016-205 was an open-label, randomized, dose ranging study to determine the optimal starting dose, efficacy and safety of patiromer in treating hyperkalemia in hypertensive patients with nephropathy due to type 2 diabetes mellitus (T2DM) who were already receiving Angiotensin-converting Enzyme Inhibitor (ACEI) and/or Angiotensin II Receptor Blocker (ARB) drugs, with or without spironolactone.

The study consisted of the following periods:
  • Screening: Up to 10 days (1 visit)

  • Run-in for those who were not hyperkalemic at screening (Cohorts 1 and 2): up to 4 weeks (1 to 4 visits)

  • Patiromer Treatment Initiation: first 8 weeks of patiromer treatment (a minimum of 10 visits)

  • Patiromer Long-Term Maintenance: additional 44 weeks of patiromer treatment up to a total of one year (minimum of 11 additional visits)

  • Follow-up (after patiromer discontinuation): 1 week (2 visits) OR 4 weeks (5 visits) depending on the final serum potassium level
