OR; - Received high-dose steroids (prednisone, methylprednisolone, or dexamethasone) followed by at least a stable partial hematologic response without evidence of new disease lesions or disease progression (defined as 50% increase in absolute lymphocyte count or measurable disease from nadir as specified in section 14.5 if imaging is performed) within 2 weeks of enrollment. 3. Presence of residual ATLL in peripheral blood either by morphology, histology, flow cytometry or gene rearrangement studies (T-cell clonality) during screening prior to enrollment. 4. Documented Human T-cell lymphotropic virus type 1 (HTLV-1) infection: Documentation may be serologic assay (ELISA) confirmed by Western blot or polymerase chain reaction (PCR). 5. Measurable or evaluable disease, including presence of molecular disease as evidence by T-cell clonality detected by gene rearrangement studies. 6. 18 years of age or older. 7. Karnofsky performance status (KPS) = 50% or Eastern Cooperative Oncology Group (ECOG) performance status = 3 8. Patients must have adequate end organ and bone marrow function as defined below: - absolute neutrophil count (ANC) = 1,000 cells/mm3 [Exception: Unless cytopenias are secondary to ATLL] - platelets (PLT) = 50,000 cells/mm3 [Exception: Unless cytopenias are secondary to ATLL] - Adequate hepatic function: - transaminase = 2.5 the institutional upper limit of normal (ULN), - total bilirubin = 1.5 x the institutional upper limit of normal (ULN), [Exception: Unless secondary to hepatic infiltration with lymphoma. If the elevated bilirubin is felt to be secondary to Indinavir or Atazavinir therapy (or anti-HIV medications), patients will be allowed to enroll.] - Creatinine clearance (CrCl) = 40 mL/min, [Exception: Unless secondary to renal involvement by lymphoma is suspected.] 9. Patients who are human immunodeficiency virus positive (HIV+) are also eligible. 10. Females of childbearing potential (CBP) must have a negative serum pregnancy test within one week of enrollment. Women should avoid pregnancy while receiving study treatment. Males and females must agree to use adequate birth control during participation in this trial and for 3 months after completing therapy. 11. Patients receiving erythropoietin or Granulocyte-colony stimulating factor (G-CSF) from baseline are eligible. Exclusion Criteria: 1. Patients with progressive disease (after previous chemotherapy or AZT/IFNa) at the time of enrollment. 2. Patients with chronic leukemia with favorable features, or smoldering type ATLL. 3. Patients receiving any other investigational agents within 14 days prior to initiation of study therapy. (Exception: Patients actively receiving IFN-alfa-2b, PEG-IFN-alfa-2b, or similar forms of IFN-alfa are permitted). 4. Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure (CHF), unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that are likely in the judgment of the Investigator(s) to interfere or limit compliance with study requirements/treatment. 5. Pregnant or breast-feeding women. 6. Known hypersensitivity to histone deacetylases (HDACs), zidovudine, belinostat or any component of the formulation(s). 7. Acute hepatitis or decompensated liver disease unless due to lymphoma. Chronic hepatitis will be required to be on prophylactic treatment during the study if provided liver function test meet criteria listed above without evidence of cirrhosis to be eligible. 8. Concurrent active malignancies, with the exception of in situ carcinoma of the cervix, non-metastatic, non-melanomatous skin cancer, or Kaposi's sarcoma not requiring systemic chemotherapy. 9. Known New York Heart Association (NYHA) Class 3 or 4 heart disease as per Appendix D. 10. Known ejection fraction < 45% or institutional limit of normal range 11. Psychological, familial, sociological or geographical conditions likely in the judgment of the Investigator(s) to interfere or limit compliance with study requirements/treatment. |

Primary | Proportion of Participants achieving Complete Molecular Response (CMR) | Proportion of participants achieving Complete Molecular Response after receiving protocol therapy. Complete Molecular Response (CMR) is defined as no evidence of disease at any body sites AND the disappearance of malignant clone(s), as proven by negative T-cell receptor gene rearrangement studies of peripheral blood DNA. Molecular response will be evaluated based upon T-cell clonality studies to be conducted while subjects are on Belinostat, and while subjects are receiving AZT-based maintenance treatment (after Belinostat completion). | From End of Cycle 3 to End of Maintenance Therapy, Up to 12 Months | |
Primary | Proportion of Participants with Minimal Residual Disease (MRD) | The proportion of subjects with minimal residual disease (MRD) will also be reported. Minimal Residual Disease (MRD) is defined as the presence of malignant clone(s) as determined by negative T-cell receptor gene rearrangement studies of peripheral blood DNA. | From End of Cycle 3 to End of Maintenance Therapy, Up to 12 Months | |
Primary | Proportion of Participants Experiencing Treatment-Related Serious Adverse Events and Adverse Events | Proportion of participants experiencing treatment-related serious adverse events (SAEs), and adverse events (AEs). SAEs and AEs will be assessed by and assigned severity and treatment attribution using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCICTCAE), Version 4.03. | Up to 13 months | |
Secondary | Rate of Participants Achieving Clinical Response | Rate of participants achieving complete response (CR) or partial response (PR) to protocol therapy. Response is assessed on the basis of clinical, radiologic, molecular and pathologic (i.e.
bone marrow) criteria. |
Up to 12 months | |
Secondary | One Year Rate of Failure-Free Survival (FFS) | Subjects will be evaluated during treatment and by follow-up assessments post-treatment. 1-year FFS is defined as the time from study treatment initiation until documented disease progression, relapse after response or death (by any cause, in the absence of progression). In the failure-free subjects, FFS will be censored at the last documented date of failure-free status. | Up to 24 months | |
Secondary | One Year Rate of Overall Survival (OS) | Follow-up for OS post-treatment will occur every 3 months during year 1 post treatment under the proposed study. OS is defined as the elapsed time from study treatment initiation to death or date of censoring. Subjects alive or those lost to follow-up will be censored at the last date known to be alive. | Up to 24 months | |
Secondary | Proportion of participants exhibiting a cytotoxic T-cell response | Cytotoxic T-Cell response will be evaluated from serum blood samples, as well as molecular evaluation of ATLL and HTLV-1 clones | Up to 13 months | |
Secondary | HTLV-1 pro-viral load | Evaluated from serum blood samples | Up to 13 months |
