About this study

Official title: A Phase 2, Multi-center, Open-label, Dose-finding Trial to Investigate the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of OPC-41061 in Patients With Chronic Renal Failure Undergoing Peritoneal Dialysis

To investigate the efficacy, pharmacokinetics, pharmacodynamics, and safety of OPC-41061 in patients with chronic renal failure who are undergoing peritoneal dialysis, using daily urine volume, body weight, and edematous conditions as parameters and conducting dose escalation every 2 days until reaching the dose that achieves urine volume increase and then performing 5-day repeated administration at the fixed dose, the final dose used in the dose escalation period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Daily Urine Volume From Baseline

    Change in daily urine volume from baseline during the repeated-administration period (For five days).

    Measured: Urine Volume on day13 minus Urine Volume at baseline(day9) on the repeated-administration period.

  2. Percent Change in Daily Urine Volume From Baseline

    Percent change in daily urine volume from baseline during the repeated-administration period (For five days).

    Measured: 100%*<Urine Volume on day13 minus Urine Volume at baseline(day9) on the repeated-administration period/Urine Volume at baseline(day9) on the repeated-administration period>

Secondary outcomes (2)
  1. Change in Body Weight From Baseline

    Change in body weight from baseline during the repeated-administration period(For five days).

    Measured: Body weight on day13 minus Body weight at baseline(day9) on the repeated-administration period

  2. Percent Change in Body Weight

    Percent change in body weight from baseline during the repeated-administration period(For five days).

    Measured: 100%*<Body weight on day13 minus Body weight at baseline (day9)/Body weight at baseline(day9)>

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing OPC-41061 in people with Chronic Renal Failure, run by Otsuka Pharmaceutical Co., Ltd. at 6 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Jan 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Daily Urine Volume From Baseline (time frame: Urine Volume on day13 minus Urine Volume at baseline(day9) on the repeated-administration period.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jan 2016.
