A-RGEMOX in the Treatment of Early Relapsed/Refractory DLBCL

June 23, 2024 updated by: Yang haiyan, Zhejiang Cancer Hospital

Prospective, Single-center, Phase II Clinical Study of Anlotinib in Combination With Rituximab，Gemcitabine and Oxaliplatin (A-RGEMOX) in the Treatment of Early Relapsed/Refractory Diffuse Large B-cell Lymphoma

As the most common subtype of lymphoma, diffuse large B-cell lymphoma (DLBCL) is an aggressive but potentially curable malignancy. However, patients with early relapse (relapse within 12 months since diagnosis or the end of first-line treatment, ER) or primary refractory had an even worse prognosis. Thus, the investigators plan to evaluate the efficacy and safety of anlotinib combined with rituximab, gemcitabine, oxaliplatin (A-RGEMOX) in the treatment of early relapsed/refractory diffuse large B-cell lymphoma.

Detailed Description

Diffuse large B-cell lymphoma (DLBCL), the most common subtype of lymphoma, accounts for about 30%-40% of non-Hodgkin's lymphomas and is highly heterogeneous in terms of clinical presentation and biological behavior. About 10% of patients are resistant to first-line immunochemotherapy, and up to 30%-40% of patients will relapse after treatment. Patients with relapsed/refractory (R/R) DLBCL showed poor prognosis, with a median overall survival of only 6.3 months. Those with early relapse (relapse within 12 months since diagnosis or the end of first-line treatment, ER) or primary refractory had an even worse prognosis. So there is an unmet need for treatment in this population. Previous reports and our unpublished data showed the potential connection between angiogenesis and first-line treatment failure. Accordingly, we assume that the combination of anlotinib and RGEMOX regimen may improve the response rate of patients with early relapsed/refractory DLBCL, increasing the feasibility of follow-up ASCT, and improving long-term survival of this subgroup of patients.

  • Must meet one of the following conditions:

    1. Early relapse: response (≥PR) to first-line systemic therapy (including rituximab and anthracyclines) and disease progression within 12 months after the end of treatment;
    2. Refractory: first-line treatment includes rituximab and anthracyclines, and no response has been achieved with the most recent systemic treatment (≥PR).
  • At least one evaluable or measurable lesion that meets Lugano2014 criteria (evaluable lesion: PET/CT examination showing increased uptake in lymph nodes or extranodal areas (higher than liver) and PET/CT and/or CT consistent with lymphoma; Measurable lesions: nodular lesions >15mm in length or extragendal lesions >10mm in length with increased FDG uptake).

  • Adequate organ and bone marrow function, no serious hematopoietic dysfunction, abnormal heart, lung, liver, kidney function and immune deficiency:
