Summary

This early-phase study tested a new treatment called LCAR-AMDR cells in 4 people with acute myeloid leukemia that had come back or not responded to standard therapy. The treatment uses specially engineered immune cells to target two proteins (CLL1 and CD33) on leukemia cells. The main goals were to check safety and find the right dose. The study was terminated early, so results are limited.
