Brief Summary:
The purpose of this trial is to assess the efficacy of E7777 in participants with recurrent or persistent Cutaneous T-Cell Lymphoma (CTCL) in Stage I - III participants as assessed by objective response rate (ORR). A lead-in dose-finding part was used to determine dose level 9 microgram per kilogram (mcg/kg) E7777 that is being used to test efficacy and safety.

Condition or disease Intervention/treatment Phase
Persistent or Recurrent Cutaneous T-Cell Lymphoma Drug: E7777 9 mcg/kg Phase 3

Detailed Description:
This is a multicenter, open-label, single-arm study of E7777 in participants with recurrent or persistent CTCL. The study consists of an initial Lead-in part (to select recommended dose of E7777 for Main part), followed by the Main part (to test efficacy). Lead in part is complete and main study is ongoing. Participants will move through three phases while on study: Pretreatment Phase, Treatment Phase, and Extension Phase and a Follow-up Period.
