Clinical trials

This purpose of this study is to help to evaluate the pharmacokinetic (PK) profile of pralatrexate when administered to patients with various degrees of hepatic impairment and to evaluate the safety and establish the dosing recommendations for pralatrexate administered once weekly for 6 weeks of every 7-week treatment cycle in patients with hepatic impairment. Pharmacokinetics (or PK) is the study of how your body absorbs, breaks down, and removes a study drug.

Part 1: This is a 5 Arm study primarily to determine the best dose out of the two dose levels of Belinostat and Pralatrexate combined with CHOP/COP in newly diagnosed PTCL patients based on Safety for part 2 study. Part 2 (Efficacy and Safety): This is a 3 Arm study. Patients with previously untreated PTCL will be randomized 1:1:1 into 1 of 3 treatment groups: 2 experimental treatment groups (Bel-CHOP or Fol-COP) or 1 active comparator treatment group (CHOP). Patients will be treated for up to 6 cycles. The primary objective is to compare the Progression Free Survival of patients with newly diagnosed PTCL treated for up to 6 cycles with Beleodaq (belinostat) in combination with CHOP (Bel-CHOP) or Folotyn (pralatrexate injection) in combination with COP (Fol-COP) to CHOP alone.
