Immune checkpoint inhibitors, specifically those targeting PD-1, are promising candidates for treatment of advanced-stage CTCL. In a phase II, single-arm study, pembrolizumab (Keytruda®) demonstrated an overall RR of 38% in pretreated patients with MF and SS [19]. PD-1 inhibitors are generally well-tolerated with some immune-related toxicities. Due to their relatively good safety profiles, multiple clinical trials are underway investigating PD-1 inhibitors in combination with radiotherapy, romidepsin, or decitabine and pralatrexate in CTCL.
