NCT00890279

Brief Summary

This phase II study examines the safety and efficacy of combination therapy for hypertension in patients with autosomal dominant polycystic kidney disease (ADPKD). This study examines the safety and efficacy of combination therapy by imidapril (ACEI) or cilnidipine (CCB) in ADPKD patients whose blood pressure is not controlled under 120/80 mmHg by candesartan (ARB) alone.

Outcome Measures

Primary Outcomes (1)

  • eGFR

    every 6 months

Secondary Outcomes (3)

  • Kidney Volume measured by MRI

    every 3 months to every 2 years

  • Serum creatinine level

    every 3 months to every 2 years

  • Induction of hemodialysis, cardiovascular events and central nervous vascular events

    every 3 months to every 2 years

Study Arms (2)

Cilnidipine

EXPERIMENTAL

The patients whose blood pressure is not controlled under 120/80 with ARB alone are randomized into group A or B. In group A, blood pressure is controlled by Candesartan plus Cilnidipine.

Drug: Cilnidipine

Imidapril

ACTIVE COMPARATOR

The patients whose blood pressure is not controlled under 120/80 with ARB alone are randomized into group A or B. In group B, blood pressure is controlled by Candesartan plus Imidapril.

Drug: Imidapril

Interventions

Cilnidipine up to 20 mg

Also known as: ATELEC
Cilnidipine

Imidapril up to 10 mg per day

Also known as: TANATRIL
Imidapril
