The purpose of the study is to determine whether tolvaptan is effective and safe for the treatment of late-stage chronic kidney disease due to autosomal dominant polycystic kidney disease (ADPKD)

Condition Intervention Phase
Chronic Kidney Disease
Autosomal Dominant Polycystic Kidney Disease
Drug: Tolvaptan (OPC-41061)
Drug: Placebo
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 3b, Multi-center, Randomized-withdrawal, Placebo-controlled, Double-blind, Parallel-group Trial to Compare the Efficacy and Safety of Tolvaptan (45 to 120 mg/Day, Split-dose) in Subjects With Chronic Kidney Disease Between Late Stage 2 to Early Stage 4 Due to Autosomal Dominant Polycystic Kidney Disease

Primary Outcome Measures:
  • Treatment difference in the change of eGFR from pre-treatment baseline to post-treatment follow-up, normalized (divided) by each subject's treatment duration [ Time Frame: prior to and post 13 1/2 months of treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Treatment difference in annualized slope of eGFR calculated for individual subjects using an appropriate baseline and available, post-randomization, on-treatment assessments [ Time Frame: prior to and post 13 1/2 months of treatment ] [ Designated as safety issue: No ]
  • Plasma tolvaptan and metabolites, including DM-4103 plasma concentrations [ Time Frame: Day -1 through Month 15 1/2 ] [ Designated as safety issue: No ]
  • Uosm and urine specific gravity [ Time Frame: Day -1 through Month 15 1/2 ] [ Designated as safety issue: No ]

Estimated Enrollment: 1300
Study Start Date: May 2014
Estimated Study Completion Date: October 2016
Estimated Primary Completion Date: October 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Tolvaptan
Tolvaptan (OPC-41061)
Drug: Tolvaptan (OPC-41061)
Tolvaptan tablets (15 or 30 mg) will be self-administered orally as split-dose regimens, once upon awakening and another approximately 8 to 9 hours later.
Placebo Comparator: Placebo
Drug: Placebo
Matching placebo tablets will be self-administered orally as split-dose regimens, once upon awakening and another approximately 8 to 9 hours later

Detailed Description:

The protocol will extend the understanding of the efficacy and safety of tolvaptan treatment in ADPKD patients with late stage 2 to early stage 4 CKD (chronic kidney disease).

This trial will compare the efficacy of tolvaptan treatment in reducing the change in estimated glomerular filtration rate (eGFR) from pre-treatment baseline to post-treatment follow-up, as compared with placebo, in subjects who tolerate tolvaptan during an initial run-in period. The change in eGFR, calculated by the Chronic Kidney Disease-Epidemiology (CKD-EPI) formula, will provide kidney function data that are complementary to the data demonstrating the benefits previously observed primarily in ADPKD subjects with earlier stages of disease.

Also, it will be compared the efficacy of tolvaptan treatment in reducing the decline of annualized eGFR slope, as compared with placebo, in this type of subjects. Finally, it will be compared the overall and hepatic safety profile of tolvaptan with placebo and to compare incidence of ADPKD complications (outcomes) during the trial


Ages Eligible for Study:   18 Years to 65 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male and female subjects with eGFR between 25-65 mL/min/1.73m2 (if aged 18 to55) or eGFR between 25-44 mL/min/1.73m2 (if aged 56 to <66)
  • Tolvaptan naïve
  • Diagnosis of ADPKD by modified pei-Ravine criteria 1.3 cysts per kidney by sonography or 5 cysts by CT or MRI with family history of ADPKD or 2.10 cysts per kidney by any radiologic method and exclusion of other cystic kidney diseases if without family history
