Brief Summary:
The purpose of this study is to estimate the overall response rate of subjects with relapsed or refractory Adult T-cell Leukemia-Lymphoma (ATL).

Condition or disease Intervention/treatment Phase
Adult T-cell Leukemia-Lymphoma Biological: KW-0761 Drug: Pralatrexate Drug: gemcitabine plus oxaliplatin Drug: DHAP Phase 2

Detailed Description:
CCR4 expression in ATL patients has been demonstrated to be very high and has been associated with shorter survival compared with CCR4-negative patients. KW-0761, a monoclonal antibody targeted to CCR4, has been shown to be safe and tolerable in several clinical trials in subjects with a variety of T-cell malignancies, including ATL, mycosis fungoides and Sézary syndrome. The objective of this study is to estimate the overall response rate of KW-0761 for subjects with relapsed or refractory ATL.

Primary Outcome Measures :
  1. Overall Response Rate [ Time Frame: every 8 weeks from date of randomization until the date of first documented progression or date of death from any cause, whichever came first ]

    Overall Response Rate was determined based on the response in all compartments (lymph nodes, extranodal masses, spleen/liver, skin, peripheral blood, and bone marrow), referencing Tsukasaki, 2009 as follows: Complete Response (CR) = All compartments involved with disease must be CR; Uncertified Complete Response (CRu) = > 75% decrease in lymph nodes and/or extranodal disease with all other compartments involved with disease CR; Partial Response (PR) = If any compartment is CR/PR and all other compartments involved with disease are at least SD; Stable Disease (SD) = All compartments involved with disease are SD; Progressive Disease (PD) = PD in any compartment.

    Lymph node and extranodal masses response ≥50% decrease by CT, skin response ≥50% decrease in mSWAT score; blood response ≥50% decrease in malignant cells by flow cytometry; normal bone marrow if abnormal at baseline. PD equals New or ≥50% increase in any compartment.

Secondary Outcome Measures :
  1. Progression Free Survival [ Time Frame: From date of randomization until the date of first documented progression, start of alternative therapy, or date of death from any cause, whichever came first, up to 36 months ]
    Progression-free survival was defined as the time from the first date of treatment until the date that PD or death was first reported. Disease progression included PD in any compartment per ATL response criteria, clinical progression at the end of the randomized treatment, or disease progression reported during the follow-up period. The date of PD was the earliest date at which disease progression could be declared.

  2. Overall Survival [ Time Frame: up to 36 months ]
    The estimates and summary statistics for OS were calculated based on Kaplan-Meier method, and the median OS was 4.9 months for subjects randomized to the mogamulizumab group versus 6.87 months for subjects randomized to the Investigator's Choice group.

  3. Change in Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) Total Score [ Time Frame: From date of randomization until the date of first documented progression, up to 36 months ]
    The FACT-Lym consists of a 27-item general core questionnaire (i.e., Functional Assessment of Cancer Therapy - General [FACT-G]) and a 15-item disease-specific questionnaire (Lymphoma Subscale). The FACT-G includes 4 domains: physical well-being, social/family well-being, emotional well-being, and functional well-being. The total FACT-Lym score (0-168) was obtained by summing individual subscale scores. Higher scores for the scales indicate better quality of life. Change was calculated as the value at the last observation minus the value at baseline.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Males and female subjects ≥ 18 years of age
  • Confirmed diagnosis of ATL (excluding smoldering subtype)
  • Subjects must currently have evidence of disease in at least one of the following:

    • Lymph nodes
    • Extranodal masses
    • Spleen or liver
    • Skin
    • Peripheral blood
    • Bone marrow
  • Relapsed or refractory after at least one prior systemic therapy regimen for ATL;
  • Eastern Cooperative Oncology Group (ECOG) performance status score of ≤ 2 at study entry

  • Significant uncontrolled intercurrent illness
  • Experienced allergic reactions to monoclonal antibodies or other therapeutic proteins;

(subjects may receive inhalation corticosteroids and replacement doses of systemic corticosteroids as needed);

Subjects on a stable dose of medium or low potency topical corticosteroids for at least 4 weeks prior to Pre-treatment Visit may continue use at the same dose, although the investigator should attempt to taper the use to lowest dose tolerable;
