Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 20 participants
Intervention Model: Single Group Assignment

Official Title: A Phase II Trial of Belinostat as Consolidation Therapy With Zidovudine for Adult T-Cell Leukemia-Lymphoma
Actual Study Start Date : December 12, 2016
Estimated Primary Completion Date : December 2021
Estimated Study Completion Date : December 2021


Arm Intervention/treatment
Experimental: Belinostat + Zidovudine
Belinostat + Zidovudine (AZT) in combination as consolidation therapy, followed by standard zidovudine (AZT)-based maintenance therapy with optional Interferon-Alfa-2b (IFNalfa-2b) or Pegylated Interferon-Alfa-2b (PEG-IFN-alfa-2b)
Drug: Belinostat
Belinostat will be administered as 1,000 mg/m2 IV infusion over 30 minutes on Days 1- 5 every 21 days (Exception as per FDA-approved Package Insert: In patients known to be homozygous for the UGT1A1*28 allele, the starting belinostat dose must be 750mg/m2) for up to 8 cycles.
Other Names:
  • PXD101
  • Beleodaq®

Drug: Zidovudine
Zidovudine shall be administered in the outpatient setting as 300 mg tablets orally (PO), three times daily (TID) for 21 days on cycles 1 to 8, followed by maintenance therapy (+/- IFN-alfa) up to the end of Month 12.
Other Name: AZT

Drug: Interferon-Alfa-2b
OPTIONAL: For subjects receiving interferon therapy at baseline, continue Interferon alfa-2b 5 million IU daily or pegylated interferon alfa-2b 1.5 μg/kg once weekly, subcutaneously (SQ) for up to 12 months.
Other Name: IFN-α-2b

Drug: Pegylated Interferon-Alfa-2b
OPTIONAL: For subjects receiving interferon therapy at baseline, continue Interferon alfa-2b 5 million IU daily or pegylated interferon alfa-2b 1.5 μg/kg once weekly, subcutaneously (SQ) for up to 12 months.

Primary Outcome Measures :
  1. Proportion of Participants achieving Complete Molecular Response (CMR) [ Time Frame: From End of Cycle 3 to End of Maintenance Therapy, Up to 12 Months ]
    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).

  2. Proportion of Participants with Minimal Residual Disease (MRD) [ Time Frame: From End of Cycle 3 to End of Maintenance Therapy, Up to 12 Months ]
    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.

  3. Proportion of Participants Experiencing Treatment-Related Serious Adverse Events and Adverse Events [ Time Frame: Up to 30 Days after the last dose of protocol therapy ]
    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.


Secondary Outcome Measures :
  1. Rate of Participants Achieving Clinical Response [ Time Frame: Up to 12 months ]

    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.


  2. One Year Rate of Failure-Free Survival (FFS) [ Time Frame: 1 Year Post-Treatment ]
    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.

  3. One Year Rate of Overall Survival (OS) [ Time Frame: 1 Year Post-Treatment ]
    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.

  4. Investigation of whether Belinostat disrupts HTLV-1 latency in vivo [ Time Frame: Baseline, at the end of Cycles 3 and 8 (each cycle is 21 days), and end of Months 9 and 12 of protocol therapy. About 13 months ]
    Serial blood samples will be collected from participants for immunologic assays as well as molecular evaluations and analysis of ATLL and HTLV-1 clones. Investigators will report the proportion of patients exhibiting a cytotoxic T-cell response upon treatment with belinostat in vivo, or specific molecular alterations from correlative studies, and correlate with response using two-sample t-test.

  5. Determination of whether Belinostat provokes an immune or cytotoxic T-cell response load in vivo [ Time Frame: Baseline, at the end of Cycles 3 and 8 (each cycle is 21 days), and end of Months 9 and 12 of protocol therapy. About 13 months. ]
    Serial blood samples will be collected from participants for immunologic assays as well as molecular evaluations and analysis of ATLL and HTLV-1 clones. Investigators will report the proportion of patients exhibiting a cytotoxic T-cell response upon treatment with belinostat in vivo, or specific molecular alterations from correlative studies, and correlate with response using two-sample t-test.

  6. Determination of impact of belinostat/AZT (+/- IFNα) on HTLV-1 proviral load as a measure of HTLV-1 infected reservoirs in vivo. [ Time Frame: Baseline, at the end of Cycles 1, 3 and 8 (each cycle is 21 days); and End of Months 9 and 12 of protocol therapy. About 13 months ]
    Serial blood samples will be collected from participants for immunologic assays as well as molecular evaluations and analysis of ATLL and HTLV-1 clones. Investigators will report the proportion of patients exhibiting a cytotoxic T-cell response upon treatment with belinostat in vivo, or specific molecular alterations from correlative studies, and correlate with response using two-sample t-test.
