About this study
Official title: A Multicenter, Uncontrolled, Open-label Phase 3 Trial of OPC-41061 in Patients With Hepatic Edema - Investigation of the Safety of Treatment at 7.5 mg Beyond 7 Days and of the Effect of Dose Escalation to 15 mg
OPC-41061 will be orally administered at 7.5 mg/day for 7 days to cirrhosis patients with ascites despite having received conventional diuretic therapy. Based on the change in body weight, on Day 7 it will be decided whether to continue administration at the same dose or to increase the dose, and then OPC-41061 will be orally administered for an additional 7 days at either 7.5 mg/day or, if diuretic effect for the initial 7-day administration is insufficient, at an increased dose of 15 mg/day. Plasma drug level, efficacy, and safety of OPC-41061 by 14-day repeated administration will be investigated.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
OPC-41061 will be orally administered at 7.5 mg/day for 7 days to cirrhosis patients with ascites despite having received conventional diuretic therapy. Based on the change in body weight, on Day 7 it will be decided whether to continue administration at the same dose or to increase the dose, and then OPC-41061 will be orally administered for an additional 7 days at either 7.5 mg/day or, if diuretic effect for the initial 7-day administration is insufficient, at an increased dose of 15 mg/day. Plasma drug level, efficacy, and safety of OPC-41061 by 14-day repeated administration will be investigated.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing OPC-41061 in people with Cirrhosis, 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 7 inclusion and 20 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 11 Apr 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 4 Mar 2014). 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?
Body Weight (time frame: Baseline, Day 14 or end of administration). 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 11 Apr 2016.
