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

6. juli 2026 oppdatert av: 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).

Detaljert beskrivelse

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.

Intervensjon / Behandling
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.

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Best Overall Response Rate (ORR)
Tidsramme: From treatment initiation until disease progression or start of new anti-lymphoma therapy, assessed up to approximately 2 years
ORR is defined as the proportion of participants achieving a best overall response of complete response (CR) or partial response (PR), assessed by the investigator according to the Lugano 2014 response criteria for malignant lymphoma.
From treatment initiation until disease progression or start of new anti-lymphoma therapy, assessed up to approximately 2 years
