Design outcomes

Primary

MeasureTime frame
Main Objective: To determine the efficacy (as assessed by reduction in urine albumin creatinine ratio) of Lokelma when compared to placebo in patients with type 1 or type 2 diabetes and nephropathy with hyperkalemia;Secondary Objective: To evaluate the change in eGFR during treatment with Lokelma when compared to placebo in patients with type 1 or type 2 diabetes and nephropathy with hyperkalemia. To evaluate whether treatment with Lokelma is associated with changes in 24h urinary sodium and potassium excretion ;Primary end point(s): Efficacy (as assessed by reduction in urine albumin creatinine ratio) of Lokelma compared to placebo.;Timepoint(s) of evaluation of this end point: At the beginning of the trial and after 12 weeks of treatment

Secondary

MeasureTime frame
Secondary end point(s): To evaluate the change in eGFR during treatment with Lokelma when compared to placebo in patients with type 1 and type 2 diabetes and nephropathy with hyperkalemia. To evaluate whether treatment with Lokelma is associated with changes in 24h urinary sodium and potassium excretion;Timepoint(s) of evaluation of this end point: At the beginning of the trial and after 12 weeks of treatment
