Detailed Description

This trial is a phase I/II study , which is designed to evaluate the safety, tolerance, pharmacokinetic characteristics, receptor occupancy (RO), immunogenicity and effectiveness of LBL-019 monotherapy or combined with anti-PD-1 antibody in patients with advanced malignant tumors. Approximately 244-486 subjects with advanced malignant tumors will be enrolled.

The study was divided into two phases: Phase I (Part A single therapy dose escalation and Part B combination therapy dose escalation) and Phase II (Part A single therapy dose expansion and Part B combination therapy dose expansion) .

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
