Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 21 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-label, Phase 1b Study of ACP 196 in Subjects With Relapsed or Refractory de Novo Activated B-cell (ABC) Subtype of Diffuse Large B-Cell Lymphoma
Actual Study Start Date : August 7, 2014
Actual Primary Completion Date : June 30, 2020
Estimated Study Completion Date : December 31, 2025

Arm Intervention/treatment
Experimental: Acalabrutinib Drug: Acalabrutinib
Other Name: ACP-196

Primary Outcome Measures :
  1. Safety Profile of Acalabrutinib in Subjects With Relapsed or Refractory ABC DLBCL. [ Time Frame: SAEs collected from time of consent; TEAEs beginning after first dose and continuing through 30 days (+/- 7 days) after last dose. ]
    Safety assessments included SAEs TEAEs, including AEs leading to discontinuation of study drug or dose reduction.

Secondary Outcome Measures :
  1. Area Under the Plasma Concentration (AUC) [ Time Frame: 1 Cycle (28 days) ]
    To Characterize the Pharmacokinetic parameter AUC of acalabrutinib

  2. Maximum Observed Plasma Concentration (Cmax) [ Time Frame: 1 Cycle (28 days) ]
    To Characterize the Pharmacokinetic parameter Cmax of acalabrutinib

  3. Evaluate Pharmacodynamic (PD) Effects (Done at US Sites Only) [ Time Frame: 2 Cycles (1 cycle = 28 days) and at end of treatment ]
    To evaluate the concentration pharmacodynamic effects of acalabrutinib

  4. Evaluate Activity of Acalabrutinib as Measured by Overall Response Rate (ORR) [ Time Frame: From enrollment to the date of disease progression, assessed up to Cycle 48 (1 cycle is 28 days) ]
    To evaluate the activity of acalabrutinib as measured by ORR
