October 2, 2019 updated by: Otsuka Pharmaceutical Co., Ltd.

A Phase 2, Multicenter, Placebo-controlled, Double-blind, Randomized, Parallel-group Trial to Investigate the Efficacy and Safety of Orally Administered Tolvaptan (OPC-41061) in Patients With Chronic Renal Failure Undergoing Hemodialysis or Hemodiafiltration

This is a study to investigate the efficacy and safety of OPC-41061 by 24-week oral administration of OPC-41061 at 15-mg or 30-mg or placebo in patients with chronic renal failure who are undergoing hemodialysis or hemodiafiltration and who have daily urine volume of at least 500 mL/day.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 80 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Daily Urine Volume
Time Frame: Baseline，End of the treatment
Change in daily urine volume from baseline to the end of the treatment was calculated using descriptive statistics.
Baseline，End of the treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
