- Treatment-emergent adverse events (TEAEs) including determination of DLTs and serious AEs (SAEs) [ Time Frame: up to 24 months ]Adverse events will be assessed, and severity will be assigned by using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0.
- MTD or RDE or RP2D [ Time Frame: up to 24 months ]maximal tolerated dose, recommended dose for expansion or recommended phase 2 dose
- DCR [ Time Frame: up to 24 months ]DCR will be documented as the proportion of patients with best overall response of CR, PR, or stable disease (SD). DCR per RECIST v1.1, iRECIST, and Cheson/Lugano criteria.
- PK parameter AUC [ Time Frame: up to 24 months ]Area under the serum concentration versus time curve (AUC) will be determined.
- PK parameter Cmax [ Time Frame: up to 24 months ]Peak Plasma Concentration (Cmax) will be summarized.
- PK parameter t1/2 [ Time Frame: up to 24 months ]Serum concentration half-life t1/2 will be summarized.
- ADA to LVGN6051 [ Time Frame: up to 24 months ]The presence of ADA directed against LVGN6051 will be determined.
