Belinostat in Patients With Relapsed or Refractory Peripheral T-Cell Lymphoma: Results of the Pivotal Phase II BELIEF (CLN-19) Study
Purpose Peripheral T-cell lymphomas (PTCLs) represent a diverse group of non-Hodgkin lymphomas with a poor prognosis and no accepted standard of care for patients with relapsed or refractory disease. This study evaluated the efficacy and tolerability of belinostat, a novel histone deacetylase inhibitor, as a single agent in relapsed or refractory PTCL. Patients and Methods Patients with confirmed PTCL who experienced progression after ≥ one prior therapy received belinostat 1,000 mg/m2 as daily 30-minute infusions on days 1 to 5 every 21 days. Central assessment of response used International Working Group criteria. Primary end point was overall response rate. Secondary end points included …
Belinostat, a novel pan-histone deacetylase inhibitor (HDACi), in relapsed or refractory peripheral T-cell lymphoma (R/R PTCL): Results from the BELIEF trial.
8507 Background: Therapies approved in US for R/R PTCL have overall response rates (ORR) of 25%-27%. The need for new therapies persists. BELIEF is a pivotal, single-arm study of belinostat in patients with R/R PTCL after failure of ≥1 prior systemic therapies. Methods: Entry criteria were measurable PTCL, platelets ≥ 50,000/µL, no prior HDACi therapy, and adequate organ function. PTCL was confirmed by central pathology review (CPRG). Belinostat 30 min IV infusion at 1000 mg/m2was administered on days 1–5 of a 3 week cycle until progression or unacceptable toxicity. Tumor response was assessed by Cheson 2007 criteria. The primary endpoint was ORR. Results: Patients with R/R PTCL (N=129, 53…
