The purpose of this study is to assess efficacy and safety of belinostat in participants with relapsed or refractory peripheral T-cell lymphoma (PTCL), who failed at least one prior systemic therapy.
This is an open-label, multicenter, single arm efficacy and safety study in participants with relapsed or refractory peripheral T-cell lymphoma, who have failed at least one prior systemic therapy.

Approximately 120 participants will be enrolled. Participants will be treated with 1000 mg/m^2 belinostat administered as a 30-minute IV infusion on Days 1-5 of every 3-week cycle until there is disease progression or unmanageable treatment-related toxicities.

The primary study endpoint is objective response rate (ORR) based on the International Harmonization Project (IHP) revision International Working Group (IWG) criteria. Safety will be evaluated during the study and for 30 days after the last administration of study drug. Adverse events and laboratory studies will be graded according to National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE) v. 3.0.

Drug Belinostat

  • Other names: PXD101

Belinostat Experimental

Belinostat 1000 mg/m^2 administered as a 30 minute IV infusion on Days 1-5 of every 3-week cycle until disease progression or unmanageable treatment-related toxicities.

Criteria

Inclusion criteria:

A histologically confirmed diagnosis of PTCL
Participants must have relapsed or refractory disease after at least one prior systemic anticancer regimen. Systemic anticancer therapy is defined as chemotherapy or immunotherapy administered systemically.
Participants must have at least one site of disease measurable in two dimensions by computed tomography (CT).
Age ≥ 18 years.
Adequate bone marrow, liver, and renal functions.
Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
Negative pregnancy test for women of childbearing potential.

Exclusion criteria:

Relapse within 100 days of autologous or allogeneic bone marrow transplant.
Prior histone deacetylase (HDAC) inhibitor therapy.
Co-existing active infection or any medical condition likely to interfere with trial procedures.
Severe cardiovascular disease.
Clinically significant central nervous system disorders with altered mental status or psychiatric disorders precluding understanding of the informed consent process and/or completion of the necessary studies.
Active concurrent malignancy (except adequately treated non-melanoma skin cancer or carcinoma in situ of the cervix).
Symptomatic or untreated central nervous system (CNS) metastases.
Pregnant or breast-feeding women.
Known infection with human immunodeficiency virus (HIV), hepatitis B or hepatitis C.

All Events

Event Type Organ System Event Term Belinostat

Objective Response Rate

Objective response rate was defined as the percentage of participants with a complete response (CR) or a partial response (PR) according to International Working Group (IWG) criteria. The response was assessed based on clinical and radiological criteria. CR is defined as the disappearance of all evidence of disease. PR is defined as a regression of measurable disease and no new sites. As pre-defined, the primary endpoint analysis for this study was based on the Independent Review Committee (IRC) assessment of response.

95% Confidence Interval: 18.3 to 34.6

Time to Response

Time to response was defined as the time (in weeks) from first administration of treatment until first response. Response is defined as complete response (CR) or partial response (PR). CR is defined as the disappearance of all evidence of disease. PR is defined as a regression of measurable disease and no new sites.

Full Range: 4.3 to 50.4

Duration of Response

The Duration of Response was assessed by IWG criteria per the IRC from the date the measurement criteria were first met for CR or PR (whichever status was recorded first) until the first subsequent date that relapse or progression was documented. It was estimated by the Kaplan-Meier method. Response is defined as complete response (CR) or partial response (PR). CR is defined as the disappearance of all evidence of disease. PR is defined as a regression of measurable disease and no new sites.

Time to Progression

Time to progression was defined as the time (in months) from first administration of treatment to the date of disease progression based on tumor assessments made according to the IWG criteria as assessed by the IRC. The progression is defined as any new lesion or increase by ≥ 50% of previously involved sites from nadir.

95% Confidence Interval: 1.5 to 2.9

Progression Free Survival

Progression-free survival (PFS) was the duration of time from first administration of study treatment to date of first documented progression or death from any cause. It was based on tumor assessments made according to the IWG criteria as assessed by the IRC. The progression is defined as any new lesion or increase by ≥ 50% of previously involved sites from nadir.

Overall Survival

Overall Survival was the time from first administration of study treatment until the date of death.

95% Confidence Interval: 6.1 to 13.9

Number of Participants With At Least One Serious Treatment-Emergent Adverse Event (TEAE)

A TEAE was defined as an event with an onset date and time on or after the first dosing start date and time, or on or after the first dosing start date if the onset time was missing. A serious TEAE was any untoward medical occurrence that at any dose results in death, prolonged hospitalization, persistent or significant disability or congenital abnormalities.
