ZR2 Followed by Immunochemotherapy in Elderly Patients With Newly-diagnosed DLBCL

October 16, 2023 updated by: Yang haiyan, Zhejiang Cancer Hospital

Prospective, Single-arm, Phase II Clinical Study of Rituximab, Lenalidomide, and Zanubrutinib Combination Regimen Followed by Immunochemotherapy in the Treatment of Elderly Patients With Newly-diagnosed 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. The poor prognosis of elderly DLBCL patients may be related to the biological behavior of the disease, more comorbidities, poor performance status, and inability to tolerate standard-intensity immunochemotherapy. The investigators plan to use ZR2 regimen(rituximab, lenalidomide and zanubrutinib) for 2 cycles followed by immunochemotherapy for up to 4 cycles in elderly newly diagnosed DLBCL patients.

Detailed Description

DLBCL mostly occurs in the elderly, with a median age at diagnosis of 66 years. Age over 60 years is a poor prognostic factor for DLBCL and is included in the International Prognostic Index (IPI) to stratify patients for prognosis. So there is an unmet need for treatment in this population. Both lenalidomide and BTK inhibitor single drugs have shown certain efficacy in DLBCL patients, and many studies have also explored the effectiveness of rituximab, lenalidomide and BTK inhibitor combination regimen in the treatment of DLBCL. Therefore, the investigators plan to use ZR2 regimen(rituximab, lenalidomide and zanubrutinib) for 2 cycles to reduce tumor burden, improve the patient's physical condition, and improve the tolerance to immunochemotherapy in elderly newly diagnosed DLBCL patients. Up to 4 cycles of immunochemotherapy were then administered sequentially in order to reduce the overall chemotherapy intensity of the patients and improve the long-term quality of life of the patients.
