Study of Mivavotinib (CB-659) in Relapsed/Refractory Diffuse Large B-Cell Lymphoma (DLBCL)

Approximately 50 patients will be randomized 1:1 to one of two dose/schedule cohorts: one with a continuous dosing schedule (100 mg QD) and one with an induction dosing schedule (120 mg QD x 14 days, then 80 mg QD starting Day 15). Patients will receive treatment with mivavotinib until disease progression, unacceptable toxicity, withdrawal of consent, or death.
