Protocol Summary

Protocol No.: OCR13264

Sponsor Protocol No.: PCYC-1123-CA

Study Title
A Multicenter Open-Label Phase 1 b/2 Study of the Brutons Tyrosine Kinase (BTK) Inhibitor, Ibrutinib, in Combination with Lenalidomide and Rituximab in Subjects with Relapsed or Refractory Diffuse Large B-Cell Lymphoma

Principal Investigator(s)
Dang, Nam

This Phase 1b/2 study is designed to assess the safety and efficacy of ibrutinib in combination with lenalidomide and rituximab in subjects with relapsed/refractory Diffuse Large B-Cell Lymphoma (DLBCL) not eligible for transplant.

Phase 1b: In the dose escalation portion of the study, up to four cohorts may be explored and lenalidomide dose escalation will follow the 3+3+3 principle for MTD determination.

Phase 2: This will be conducted as an international, multicenter, randomized open-label study. Eligible subjects will be randomized in a 1:1 ratio into 2 arms to receive either ibrutinib, lenalidomide and rituximab (Treatment Arm A) or ibrutinib and lenalidomide (Treatment Arm B).

Phase: Phase I/II

Age Group: Adult

Scope: National

Phase 1: Dose Level -1, Level 1, Level 2, Level 3
Ibrutinib PO+ Lenalidomide (PO) + Rituximab (IV)

Phase 2 - Arm A
Ibrutinib PO+ Lenalidomide (PO) + Rituximab (IV)

Phase 2 - Arm B
Ibrutinib PO+ Lenalidomide (PO)
