Purpose: Denileukin diftitox (DD)-cxdl is a fusion protein comprising diphtheria toxin fragments A and B and human interleukin-2. This phase III, multicenter, open-label, single-arm registrational trial evaluated the efficacy and safety of DD-cxdl in patients with relapsed/refractory (R/R) cutaneous T-cell lymphoma (CTCL).
Patients And Methods: In the main study, which followed a dose-finding lead-in, DD-cxdl was administered intravenously daily (5 days; 9 µg/kg/d once daily) every 21 days for up to eight cycles.

We identified immunologic transitions that interlink mycosis fungoides with SS using single-cell transcriptome analysis in parallel with high-throughput T-cell receptor sequencing.
