Overview
Brief Summary
The purpose of this Phase 1 study is to determine the maximum tolerated dose (MTD) through observation of dose limiting toxicity (DLT), which is in advance defined, in patients with peripheral or cutaneous T-cell lymphoma.

Outcomes
Primary Outcomes
Maximum Tolerated Dose (MTD) and Recommended Dose (RD)
Time Frame: For each dose, first dose of study drug (Cycle 1 Day 1) to end of Cycle 1 (Day 21) (1 cycle = 3 weeks)
The MTD was defined as the maximum tolerated dose observed after the evaluation of dose limiting toxicity (DLT) in Cycle 1 with 6 participants. If it was judged that the dose was not tolerated and DLT was confirmed in only 3 participants in the lower dose cohort, 3 other participants were to be added and tolerability was evaluated with 6 participants in total. The RD was to be comprehensively determined based on the MTD and safety data. Participants not evaluable for DLT were defined as participants found to be ineligible or in whom DLT evaluation was impossible due to premature termination for reasons other than toxicities in the judgement of the Sponsor, among those who had received at least one dose of the investigational drug after enrollment.
Secondary Outcomes
- Maximum Serum Concentration (Cmax) of Denileukin Diftitox(Cycle 1 (Day 1))
- Total Clearance (CL)(Cycle 1 (Day 1))
- Time to Cmax (Tmax) of Denileukin Diftitox in Serum(Cycle 1 (Day 1))
- Volume of Distribution at Terminal Phase (Vz)(Cycle 1 (Day 1))
- Area Under the Serum Concentration-Time Curve From Time 0 to Time of Last Quantifiable Concentration (AUC(0-t))(Cycle 1 (Day 1))
- Recommended Dose(For each dose, first dose of study drug (Cycle 1 Day 1) to end of Cycle 1 (Day 21) (1 cycle = 3 weeks))
- Area Under the Serum Concentration-Time Curve From Time 0 to Infinity (AUC(0-inf))(Cycle 1 (Day 1))
- Terminal Phase Rate Constant (λz)(Cycle 1 (Day 1))
- Volume of Distribution at Steady State (Vss)(Cycle 1 (Day 1))
- Number of Participants With Non-Serious Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) as a Measure of Safety and Tolerability of Denileukin Diftitox(From date of first dose up to 30 days after the last dose of study treatment, up to approximately 4 years 2 months)
- Terminal Elimination Phase Half-life (t1/2)(Cycle 1 (Day 1))
