February 23, 2020 updated by: Korea Otsuka Pharmaceutical Co., Ltd.

Post Marketing Surveillance Study of Safety and Efficacy of Samsca® Tablets Under the "New Drug Re-Examination"

This Post-Marketing Surveillance will be conducted in accordance with the local regulation of New Drug Re-examination. The surveillance will be conducted for 6 years of the re-examination period (01Sep2011~31Aug2017). Each subject will be observed at least for 4 days during the surveillance period.

Study Overview

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.

Detailed Description

This study will be conducted as a prospective, single-arm, multicenter study. Findings on examination, diagnosis, opinions and observations implemented as per general medical practice during the observational period will be documented in the case report forms by the investigators or responsible staffs at the institution since the surveillance is an observational study.

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
Safety Measure
Time Frame: 4days
Adverse Events (AEs)
4days

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
Measure Description
Time Frame
Change of the Serum Sodium Level(mEq/L) at the First Visit and Day 4 After the First Visit
Time Frame: Follow-up at least 4 days after first Samsca® dose
In the efficacy analysis set, mean change of serum sodium level (mEq/L)on the 4th day compared to the first visit
Follow-up at least 4 days after first Samsca® dose

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
