Following the death of a 78-year-old man being treated for blastic plasmacytoid dendritic cell neoplasm (BPDCN), the FDA placed clinical holds on 2 phase I trials investigating a gene-edited allogeneic CAR T-cell (UCART) therapy known as UCART123.
. Researchers observed antitumor activity in 2 of 6 of the relapsed patients during the period of CD19-CAR-T cell persistence, whereas 2 patients who received cells while in remission remained disease-free. Of these 2 patients, 1 remained in CR for more than 8 months and the other remained in CR for 8 weeks after CAR-T infusion.
