An Open-Label, Randomized Controlled, Multicenter, Phase II Clinical Study to Evaluate the Efficacy and Safety of Rocbrutinib Monotherapy Versus Investigator's Choice of Therapy in Patients With Relapsed or Refractory Non-GCB Diffuse Large B-Cell Lymphoma
This is an open-label, randomized controlled, multicenter Phase II clinical study primarily evaluating the efficacy and safety of Rocbrutinib monotherapy compared to the investigator's choice of BR/R2 regimen in patients with non-GCB DLBCL.
• Age ≥18 years, any gender.
• Pathologically confirmed DLBCL (not otherwise specified) according to the revised 2017 WHO classification of lymphoid neoplasms, with non-germinal center B-cell-like (non-GCB) subtype confirmed by Han's algorithm (Appendix 1), based on previous pathological records or confirmed during screening. Must be able to provide sufficient tumor tissue or slides (from previous or screening biopsies) for central laboratory confirmation of pathological diagnosis (if the local pathology report is clear, patients may be enrolled and start treatment without waiting for the central pathology report).
• Patients who are refractory or have relapsed after at least two prior lines of therapy (at least one line must include an anti-CD20 antibody-containing regimen) (see section 6.3 for definition of refractory or relapsed).
• At least one measurable lesion (nodal lesion with longest diameter \>1.5 cm, extranodal lesion with longest diameter \>1.0 cm).
• Not planned for autologous stem cell transplantation (ASCT).
• Eastern Cooperative Oncology Group (ECOG) performance status score ≤2.
