Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is an open-label phase I study to evaluate the safety, pharmacokinetics, and antitumor activity of SSGJ-612 in patients with advanced malignant solid tumors expressing HER2.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The clinical trial consists of two phases. In the dose escalation stage, the accelerated titration method combined with the traditional "3+3" design will be adopted, to evaluate the safety and dose-limiting toxicity (DLT), and to determine the maximum tolerated dose (MTD) or the maximum dose of administration (MAD). In the dose expansion phase, several safe and effective dose levels of SSGJ-612 will be expanded and further evaluated in larger groups of participants.

SSGJ-612

In dose escalation phase, participants will receive one of the five increasing dose levels of SSGJ-612 respectively, intravenously (IV). During or after dose escalation, any dose levels that does not exceed the MTD can be expanded.
