About

For Phase I Dose Escalation Stage, to assess the safety and tolerability of LM-350 in patients with advanced solid tumors,determine the maximum tolerated dose (MTD) or optimal biological dose (OBD), and explore the relationship between the biomarkers and the anti-tumor activity of LM-350.

For Phase II Dose Expansion Stage, to assess the preliminary anti-tumor activity of LM-350 in patients with advanced solid tumors.

Enrollment: 80 estimated patients

Sex: All

Ages: 18+ years old
