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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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 is an open-label, multicenter, dose-escalation phase I study to assess the safety, tolerability and preliminary efficacy of KN046 in participants with all advanced solid tumors who are not able to have current standard anti-tumor therapies. The purpose of this study is to determine the maximum tolerated dose (MTD) or a biological effective dose (BED), to characterise the safety, pharmacokinetics (PK), immunogenicity, pharmacodynamics (PD) and anti-tumor activity of KN046 as a single agent in adult participants with advanced solid tumors
