Conditions

Advanced Malignancies Associated with EphA2 Expression

Brief summary

1. Treatment-emergent adverse events (TEAEs), laboratory, ECG and vital sign abnormalities using CTCAE v5.0 criteria., 2. Dose-limiting toxicities as defined in the protocol., 3. Objective response rate (ORR [CR + PR]), duration of response (DOR), clinical benefit rate (CR + PR + SD ≥4 months), time to tumor progression (TTP), progression-free survival time (PFS), rate of PFS at 6 mos., all assessed per RECIST v1.1 criteria as assessed by the Investigator, and OS.
