Brief Summary

A non-randomized, open-ended, phase I dose-escalation and dose-expansion study was designed to evaluate the safety, tolerability, antitumor efficacy, PK and immunogenic characteristics of LNF2007 in patients with advanced solid tumors

Detailed Description

A non-randomized, open-ended, phase I dose-escalation and dose-expansion study was designed to evaluate the safety, tolerability, antitumor efficacy, PK and immunogenic characteristics of LNF2007 in patients with advanced solid tumors. This study is divided into dose escalation stage and dose extension stage.

A total of 9 dose groups were designed in the dose escalation phase. The dose expansion phase is planned to be conducted in two dose groups (determined by discussion between the investigator and sponsor based on available trial data), enrolling approximately 20 participants at each dose. According to the results of dose escalation phase, the pre-excitation dose of dose extension phase is designed.

Conditions
