A Study to Evaluate the Efficacy and Safety of Genotype-guided Targeted Agents in Combination With POLA-RCHP VERSUS POLA-RCHP in Patients With Previously Untreated Diffuse Large B-cell Lymphoma
The purpose of this study is to compare the efficacy and safety of genotype-guided targeted agents in combination with polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisone (Pola RCHP-X) versus Pola RCHP in Chinese patients with previously untreated diffuse large B-cell lymphoma (DLBCL).
• Signed Informed Consent Form
• Age 18-75 years at the time of signing Informed Consent Form and willingness to comply with study protocol procedures
• Previously untreated participants with CD20-positive DLBCL
• IPI score 2-5
• ECOG Performance Status of 0, 1, or 2
• After 1 cycle of Pola-R-CHP, ctDNA decreased by \< 3.0 LFC
• Life expectancy ≥ 6 months
• Left ventricular ejection fraction (LVEF) ≥ 50% on cardiac multiple-gated acquisition (MUGA) scan or cardiac echocardiogram (ECHO)
• Adequate hematologic function (unless due to underlying disease, as established for example, by extensive bone marrow involvement or due to hypersplenism secondary to involvement of the spleen by DLBCL per the investigator for which blood product transfusions are permitted) defined as follows:
‣ Hemoglobin ≥ 9.0 g/dL without packed RBC transfusion during 7 days before first treatment
⁃ ANC ≥ 1.0 x 10\^9/L
⁃ PLT ≥ 75 x 10\^9/L
