5.1       Pharmacodynamic properties


The ability of patiromer to enable concomitant spironolactone treatment in patients with resistant hypertension and CKD was further investigated in a randomised, double-blind, placebo-controlled study over 12 weeks. Normokalaemic patients initiated spironolactone at 25 mg QD together with their randomised treatment (patiromer 8.4 g QD or placebo). Patiromer/placebo was titrated weekly (up to 25.2 g QD) to maintain serum potassium 4.0 mEq/L and 5.1 mEq/L. At week 3 or after, spironolactone dose was increased to 50 mg QD for subjects with systolic blood pressure 120 mmHg and serum potassium 5.1 mEq/L.


Of the 295 randomized patients  receiving study treatment (patiromer 147; placebo 148), mean age was 68.1 years, 51.9% were men, 98.3% were Caucasian, and mean eGFR was 35.73 mL/min/1.73m2. At randomization, mean baseline serum potassium values were 4.74 mEq/L for patiromer and 4.69 mEq/L for placebo. The primary efficacy endpoint, the proportion of subjects remaining on spironolactone at Week 12, was significantly higher (p<0.0001) in the patiromer group (85.7%)  compared to the placebo group (66.2%). Significantly more patients received spironolactone 50 mg/day (69.4% versus 51.4%).


Overall, patients in the patiromer group remained on spironolactone 7.1 days longer (95% CI 2.2–12.0; p=0.0045) compared to the placebo group and received significantly higher cumulative doses of spironolactone (2942.3 (SE 80.1) mg vs 2580.7 (SE 95.8) mg, p=0.0021).

There were also significantly fewer patients in the patiromer group with serum potassium values 5.5 mEq/L (35.4% vs. 64.2%, p<0.001).


At Week 12, the mean systolic blood pressure had decreased by 11.0 mmHg (SD 15.34) in the spironolactone + placebo group and by 11.3 mmHg (SD 14.11) in the spironolactone + patiromer group. These decreases from baseline were statistically significant within each treatment group (p<0.0001), but not statistically significant between the groups.
