Clinical trials

B-cell non-Hodgkin lymphoma (B-NHL) is the most common type of lymphoma. Although first-line R-CHOP can cure a proportion of patients, approximately 30%-40% relapse or become refractory (R/R). CD20xCD3 bispecific antibodies, represented by glofitamab, have shown significant efficacy in clinical trials. However, large-scale real-world efficacy and safety data in Chinese clinical practice are still lacking, particularly regarding combination with different regimens and use in the relapsed population. This is a prospective, multicenter, observational registry study evaluating the efficacy and safety of CD20xCD3 bispecific antibody-containing regimens in patients with relapsed or refractory B-cell non-Hodgkin lymphoma in a real-world setting. Efficacy is assessed using the Lugano 2014 response criteria. The primary endpoint is best objective response rate (ORR).

The phase Ib part of this study aims to determine the recommended phase II dose （RP2D）of linperlisib in combination with chidamide for the treatment of peripheral T-cell lymphoma (PTCL). The phase IIa part is designed to evaluate the preliminary efficacy and safety of the linperlisib plus chidamide regimen in newly diagnosed PTCL patients. The phase IIb part compares the efficacy and safety of linperlisib combined with chidamide versus the standard CHOP (CHOP-like) regimen in newly diagnosed PTCL patients.
