Trial Information

Open-Label, Multi-Center, Phase 2 Study of Anti-CCR4 Monoclonal Antibody KW-0761 (Mogamulizumab) in Subjects With Previously Treated Peripheral T-cell Lymphoma (PTCL)

PTCL is a rare and heterogeneous disease that remains difficult to diagnose and treat. In
the majority of PTCL subtypes, patients are of older age (>60 years) and present with
advanced stage disease.With the exception of the ALCL-ALK-positive subtype that responds
well to CHOP combined chemotherapy, most PTCL subtypes become refractory even to aggressive
chemotherapy regimens or relapse. Overall survival of PTCL patients is poor compared with
that of aggressive B-cell lymphomas.Thus, novel and effective therapies are
needed.KW-0761(mogamulizumab) is a defucosylated, humanized, IgG1 mAb with enhanced antibody
dependent cellular cytotoxicity (ADCC)that binds to CCR4, a molecule that is suggested to be
significantly involved in patients with PTCL.

Inclusion Criteria:

1. ≥18 years of age at the time of enrollment;

2. Histologically confirmed diagnosis of PTCL as specified below:


- Angioimmunoblastic T-cell lymphoma

3. Failed or intolerant of at least one prior systemic anticancer therapy;

4. ECOG performance status score of ≤ 2 at study entry;

5. At least one site of disease measurable in two dimensions by computed tomography

6. Subjects who are positive for CCR4 by immunohistochemistry;

7. Resolution of all clinically significant toxic effects of prior cancer therapy to
grade ≤1 (NCI-CTCAE, v.4.0);

8. Adequate hematological hepatic and renal function.

Exclusion Criteria:

1. Subject with the following PTCL diagnoses are excluded;

- Precursor T/NK neoplasms

- Hepatosplenic T-cell lymphoma

- Subcutaneous panniculitis -like T-cell lymphoma

- Chronic lymphoproliferative disorder of NK cells

2. Have had an invasive solid tumor malignancy in the past five years except
non-melanoma skin cancers, melanoma in situ, cervical carcinoma in situ,
ductal/lobular carcinoma in situ of the breast, or localized prostate cancer with a
current PSA of ≤ 0.1 ng/ml who is currently without evidence of disease;

3. Relapsed less than 75 days of autologous stem cell transplant;

4. History of allogeneic stem cell transplant;

5. Evidence of central nervous system (CNS) metastasis;

6. Psychiatric illness, disability or social situation that would compromise the
subject's safety or ability to provide consent, or limit compliance with study

7. Subjects with a history of moderate or severe psoriasis or with psoriasis associated
with systemic symptoms e.g. arthropathy), or with a 1st degree relative with history
of psoriasis that required medical intervention;

8. Significant uncontrolled intercurrent illness;

9. Known or tests positive for human immunodeficiency virus (HIV), hepatitis B or
hepatitis C;

10. Active herpes simplex or herpes zoster;

11. Experienced allergic reactions to monoclonal antibodies or other therapeutic

12. Known active autoimmune disease will be excluded (For example: Grave's disease;
systemic lupus erythematosus; rheumatoid arthritis; Crohn's disease);

13. Is pregnant (confirmed by beta human chorionic gonadotrophin [β-HCG]) or lactating;
Prohibited Therapies and/or Medications

14. Prior treatment with KW-0761;

15. Initiation of treatment with systemic steroids while on study is only permitted for
acute and brief complications of underlying disease (e.g., hypercalcemia) or for
treatment related side effects;

16. Initiation of treatment with topical steroids while on study is not permitted except
to treat an acute rash;

17. Have had anti-neoplastic chemotherapy, radiation, immunotherapy, or investigational
medications within 4 weeks of screening visit;

18. Subjects on any immunomodulatory drug.
