Clinical Pharmacology Trial to Investigate the Dose of OPC-61815 Injection Equivalent to Tolvaptan 15-mg Tablet in Patients With Congestive Heart Failure

July 8, 2021 updated by: Otsuka Pharmaceutical Co., Ltd.

A Multicenter, Double-blind, Randomized, Active-controlled, Parallel-group Comparison Clinical Pharmacology Trial to Investigate the Dose of OPC-61815 Injection Equivalent to Tolvaptan 15-mg Tablet in Patients With Congestive Heart Failure

The dose for intravenous administration of OPC-61815 achieving tolvaptan exposure equivalent to that for oral administration of tolvaptan 15-mg tablet will be investigated by administering OPC-61815 injection 2 to 16mg or tolvaptan 15-mg oral tablet to subjects with congestive heart failure.

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

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

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 85 years (Adult, Older Adult)
