Clinicaltrials.gov identifier NCT03939182

Recruitment Status Recruiting

Study Description

Brief summary:

The purpose of this study is to test the safety of abexinostat at different doses to find out if it can work with ibrutinib to stop the cancer from growing.

  • Condition or Disease:Diffuse Large B-cell Lymphoma
    Mantle Cell Lymphoma
  • Intervention/Treatment: Drug: Abexinostat
    Drug: Ibrutinib
  • Phase: Phase 1/Phase 2
Detailed Description


Study Design
  • Study Type: Interventional
  • Estimated Enrollment: 40 participants
  • Intervention Model: Single Group Assignment
  • Intervention Model Description: This is a phase I with dose expansion, open label single institution trial. The first stage is a standard 3+3 dose escalation trial. In the second stage, the dose expansion cohort will accrue patients at the MTD abexinostat and ibrutinib previously determined.
  • Masking: None (Open Label) ()
  • Primary Purpose: Treatment
  • Official Title: Phase I Study of Abexinostat and Ibrutinib in Diffuse Large B-cell Lymphoma and Mantle Cell Lymphoma
  • Actual Study Start Date: May 2019
  • Estimated Primary Completion Date: May 2022
  • Estimated Study Completion Date: May 2022
Arms and interventions
Arm Intervention/treatment
Experimental: Abexinostat and Ibrutinib
The investigational agents to be used in this study are ibrutinib and abexinostat. Ibrutinib will be administered once daily on a 28-day cycle. Abexinostat will be administered orally twice daily (approximately 4-6 hours apart) for 7 days a week given every other week on a 28-day cycle.
Drug: Abexinostat
Two doses of the abexinostat will be tested: 30 mg/m2 and 45 mg/m2 orally twice daily, 7 days/week given every other week during a 28-day cycle.

Drug: Ibrutinib
Ibrutinib will be given at the FDA-approved dose for mantle cell lymphoma (MCL) of 560 mg orally daily for 28 day cycle.
Outcome Measures
  • Primary Outcome Measures: 1. the MTD of abexinostat when combined with ibrutinib [ Time Frame: 1 year ]
    a standard 3+3 dose escalation scheme will be used. For any given dose an initial cohort of 3 patients will be treated at that dose. The dose level will be escalated if none of the 3 patients exhibits any DLT.
