  Purpose

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.


Condition Intervention Phase
Kidney, Polycystic, Autosomal Dominant
 Drug: Cilnidipine
Drug: Imidapril
 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase II Study for the Second-Line Treatment of Hypertension in Patients With Autosomal Dominant Polycystic Kidney Disease; ACEI vs. CCB

Secondary Outcome Measures:
  • Kidney Volume measured by MRI [ Time Frame: every 3 months to every 2 years ] [ Designated as safety issue: No ]
  • Serum creatinine level [ Time Frame: every 3 months to every 2 years ] [ Designated as safety issue: No ]
  • Induction of hemodialysis, cardiovascular events and central nervous vascular events [ Time Frame: every 3 months to every 2 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 160
Study Start Date: July 2009
Estimated Study Completion Date: November 2012
Estimated Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cilnidipine
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
Cilnidipine up to 20 mg
Other Name: ATELEC
Active Comparator: Imidapril
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
Imidapril up to 10 mg per day
Other Name: TANATRIL

Detailed Description:

Maximum dosage of candesartan is 8 mg/day. Dosage of imidapril is in the range of 2.5-10 mg/day. Dosage of cilnidipine is in the range of 5-20mg/day.
