- Brief Summary
A Phase I/II, Open-Label, Multiple Centre Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Immunogenicity and Preliminary Efficacy of LM- 302 in Combination with Toripalimab in Patients with Advanced Solid Tumors
- Detailed Description
This is a study of LM-302 in combination with toripalimab in patients with advanced solid tumors .The study includes phase I (dose escalation) and phase II (dose expansion).
