Real-World Study of Bispecific Antibody in Relapsed or Refractory B-Cell Non-Hodgkin Lymphoma

6. července 2026 aktualizováno: Yanyan Liu

A Real-World Study on the Efficacy and Safety of Bispecific Antibody in the Treatment of Patients With Relapsed or Refractory B-Cell Non-Hodgkin Lymphoma

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).

Detailní popis

Study design: Prospective, multicenter, observational (non-interventional) registry study.

Population: Patients aged >=18 years with histologically confirmed B-cell non-Hodgkin lymphoma who are relapsed or refractory after at least one prior line of therapy and who receive a CD20xCD3 bispecific antibody-containing regimen after study initiation.

Efficacy evaluation: Lugano 2014 response criteria.

Primary endpoint: Best objective response rate (ORR).

Secondary endpoints: Complete response rate (CRR), disease control rate (DCR), duration of response (DOR), time to next treatment (TTNT), progression-free survival (PFS), overall survival (OS), and safety.

Exploratory endpoints: Subgroup analyses by combination pattern (e.g., combined with chemotherapy or targeted agents) and special populations; correlation of biomarkers (e.g., peripheral blood lymphocyte subsets, T-lymphocyte mitochondrial immune analysis, cytokines) with efficacy and safety; and patient compliance and quality-of-life analyses based on electronic patient-reported outcomes (ePRO).

Planned enrollment: 200 participants. As a non-interventional study, no formal statistical hypothesis is tested; the sample size is based on the confidence-interval width method (expected ORR P=0.5, half-width d=0.07), yielding approximately 196 participants, rounded to 200.

Skupina / kohorta
Intervence / Léčba
R/R B-NHL treated with bispecific antibody
Patients with relapsed or refractory B-cell non-Hodgkin lymphoma who receive a CD20xCD3 bispecific antibody-containing regimen (e.g., glofitamab) in routine clinical practice. This is a single observational cohort; no treatment is assigned by the study.
Glofitamab, a CD20xCD3 bispecific monoclonal antibody, administered per real-world clinical practice and product labeling. As an observational study, treatment is determined by the treating physician and not by the study protocol; the intervention of interest is recorded to describe the treated population.
