Glofitamab Combined With Selinexor in Patients With Relapsed/Refractory Diffuse Large B-cell Lymphoma

Currently, patients with relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL) who have failed at least two lines of systemic therapy have a poor prognosis, and there is a significant clinical need for new treatment options. Glofitamab and selinexor have both demonstrated clinical activity as single agents in R/R DLBCL. Because their mechanisms of action are complementary and their toxicity profiles do not overlap significantly, this combination holds the potential to further improve outcomes. Therefore, this study plans to assess the efficacy and safety of glofitamab in combination with selinexor for the treatment of R/R DLBCL patients who have previously received at least two lines of systemic therapy. Enrolled patients will receive study treatments for up to 12 cycles, with each 21-day period being one cycle. Cycle 1 involves obinutuzumab pre-treatment and step-up dosing of glofitamab. From Cycle 2 to Cycle 12, patients will receive glofitamab in combination with oral selinexor. Interim efficacy evaluations will be conducted during the treatment. At the end of the 12 cycles or upon treatment discontinuation, a final efficacy evaluation will be conducted, followed by a long-term follow-up period.
