Summary

This trial aims to test a new treatment called A2B395 on patients with various types of solid tumors. The study will determine the safe dosage of A2B395 and evaluate its effectiveness in killing

Who is the study for?
This trial is for people with certain solid tumors (like colorectal, lung, breast, kidney cancers) that have a specific protein called EGFR and lack another marker known as HLA-A*02. Details on who can join are not fully provided but typically include meeting health standards and having the type of cancer being studied.
What is being tested?
The study tests A2B395, an experimental CAR T-cell therapy designed to target cancer cells in patients with specific tumor types. It includes two phases: finding a safe dose (Phase 1) and seeing if this dose can effectively kill tumor cells while sparing healthy ones (Phase 2).
What are the potential side effects?
While specific side effects aren't listed here, CAR T-cell therapies often cause immune system reactions like fever or fatigue, potential nerve damage symptoms such as confusion or seizures, and could affect blood cell counts leading to increased infection risk.
