Overview
Brief Summary
The purpose of this study is to evaluate the objective response rate (ORR) of E7777 in participants with relapsed or refractory peripheral T-cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL).
Detailed Description
This is a multicenter, single-arm, open label, Phase 2 to evaluate efficacy, safety, pharmacokinetics and immunogenicity of E7777 in participants with relapsed or refractory PTCL and CTCL.

Arms & Interventions
E7777
Participants with relapsed or refractory peripheral T-cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL) will receive 9 μg/kg/day of E7777, administered by intravenous drip infusion in 60 minutes (± 10 min) for Days 1 through 5 of each cycle in maximum of 8 cycles. Every cycle consists of 3 weeks.
Intervention: E7777
Outcomes
Primary Outcomes
Objective Response Rate (ORR)
Time Frame: From the date of administration of the first dose of the study drug until completion of the study or treatment discontinuation, up to approximately 3 years 1 month
ORR was defined as the percentage of participants whose best overall response (BOR) was complete response (CR) or partial response (PR) based on independent review of Efficacy and Safety Evaluation Committee. ORR was assessed according to modified response criteria based on the revised response criteria for malignant lymphoma (Cheson, 2007), skin lesion and peripheral blood disease were assessed according to clinical end points and response criteria in mycosis fungoides and Sezary syndrome (Olsen, 2011). CR: Disappearance of all evidence of disease; PR: Regression of measurable disease and no new sites.
Secondary Outcomes
- Duration of Response (DOR)(From the date of first documentation of CR or PR until date of the first documentation of PD or death due to any cause (whichever occurred first) up to approximately 3 years 1 month)
- Progression Free Survival (PFS)(From the date of administration of the first dose of the study drug until date of the first documentation of PD or death due to any cause (whichever occurred first) up to approximately 3 years 1 month)
- Time to Response (TTR)(From the date of administration of the first dose of the study drug until date of the first documentation of PR or CR or death due to any cause (whichever occurred first) up to approximately 3 years 1 month)
- CR Rate(From the date of administration of the first dose of the study drug until completion of the study or treatment discontinuation, up to approximately 3 years 1 month)
- Overall Survival (OS)(From date of administration of the first dose of the study drug until the date of death due to any cause up to approximately 3 years 1 month)
