Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to find out if the combination of buparlisib and ibrutinib will lead to better treatment results in patients with relapsed or refractory Follicular lymphoma, (FL) Mantle cell lymphoma (MCL) or Diffuse Large B-cell lymphoma (DLBCL). The investigators are using buparlisib and ibrutinib because both drugs seem to block different proteins that allow cancer cells to keep growing. Blocking these proteins may help by making the cancer cells undergo cell death, which will stop uncontrolled tumor growth.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Buparlisib and Ibrutinib

This is a two stage protocol comprised of a single institution phase Ib dose escalation trial. The first stage is a standard 3+3 phase I dose escalation trial to assess the safety of buparlisib and ibrutinib. The second stage is a single center expansion cohort in MCL, FL and DLBCL respectively evaluating the efficacy of buparlisib and ibrutinib combination.

Treatment will be with ibrutinib orally daily and buparlisib orally daily. A cycle is defined as 4 weeks of therapy. Therapy will continue until disease progression, intolerable toxicities or death with a maximum duration for 36 cycles, not exceeding 36 months on therapy.
