Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
This study is the first time into human study (FTIH) for HYR-PB21 for injection. The study will evaluate the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of single ascending and single subcutaneous dose of HYR-PB21 for injection in healthy adult volunteers.The results of this study are intended to be used to identify appropriate and well tolerated doses of HYR-PB21 for injection to be used in further studies. A comparison of PK/PD characteristics between HYR-PB21 for injection and EXPAREL will also be included in this study.
