Study of the Efficacy and Safety of Ublituximab in Patients With Relapsed or Refractory B-cell Non-Hodgkin Lymphoma

November 16, 2022 updated by: TG Therapeutics, Inc.

An Open Label Phase I/II Study of the Efficacy and Safety of Ublituximab in Patients With B-cell Non-Hodgkin Lymphoma Who Have Relapsed or Are Refractory After CD20 Directed Antibody Therapy

The purpose of this study is to determine whether ublituximab is safe and effective in patients with relapsed or refractory B-cell lymphoma who were previously treated with rituximab.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: ublituximab

Phase I:

4 cohorts with IV ublituximab starting with 450 mg followed by 600 mg, 900 mg or 1200 mg in each cohort (3 - 6 patients per cohort). Infusions will be on days 1, 8, 15 and 22 of cycle 1 followed by a planned maintenance with a single infusion monthly starting cycle 3. Patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) will have infusions on Days 1, 8 and 15 of cycle 1 & 2 followed by a planned maintenance with a single infusion monthly starting cycle 3. Expansion of patient enrollment in select cohorts will apply.
Drug: Ublituximab
Ublituximab is a novel monoclonal antibody targeting cluster of differentiate 20 (CD20)
