On November 22, 2021, CRISPR Therapeutics announced that the US FDA has granted CTX110 Regenerative Medicine Advanced Therapy (RMAT) designation
CTX110 locates the chimeric antigen receptor (CAR) targeting CD19 antigen into the cell's natural T cell receptor (TCR) site, and prevents the expression of endogenous TCR while introducing the CAR, thereby preventing graft-versus-host The occurrence of disease (GvHD)
