Efficacy and Safety of Pola-RCHP-X vs Pola-RCHP in Untreated DLBCL

Recruiting now · Phase 2

Conditions studied: Diffuse Large B-Cell Lymphoma

In brief

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).

You may qualify if…

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

You may not qualify if…

Contraindication to any of the individual components of Pola-RCHP or Zanubrutinib/Lenalidomide/ Decitabine
Prior solid organ transplantation or SCT
Current diagnosis of the following: Follicular lymphoma grade 3B; mediastinal grey zone lymphoma; primary mediastinal (thymic) large B-cell lymphoma; Burkitt lymphoma; PCNSL
Significant or extensive history of cardiovascular disease such as New York Heart Association Class III or IV cardiac disease or Objective Assessment Class C or D, myocardial infarction within the last 6 months prior to the start of Cycle 1, unstable arrhythmias, or unstable angina
History or presence of an abnormal ECG that is clinically significant in the investigator's opinion
Any of the following abnormal laboratory values (unless any of these abnormalities are due to underlying lymphoma):
Serum AST and ALT ≥ 2.5 x ULN
Total bilirubin ≥ 1.5 x ULN
Serum creatinine clearance < 30 mL/min (using Cockcroft-Gault formula)
Any active infection within 7 days prior to Cycle 1 Day 1 that would impact participant safety
Positive test results for chronic hepatitis B infection (defined as positive hepatitis B surface antigen [HBsAg] serology)：Participants with occult or prior hepatitis B infection (defined as positive total hepatitis B core antibody and negative HbsAg) may be included if hepatitis B virus (HBV) DNA is undetectable at the time of screening. Such participants must be willing to undergo HBV DNA testing every month and appropriate antiviral therapy as indicated
Positive test results for hepatitis C (hepatitis C virus [HCV] antibody serology testing)：Participants positive for HCV antibody are eligible only if PCR is negative for HCV RNA
Participants with a history of progressive multifocal leukoencephalopathy
Pregnancy or breastfeeding, or intention of becoming pregnant during the study or within 12 months after final dose of Pola-RCHP-X
Other concurrent and uncontrolled medical conditions that, in the opinion of the investigator, would affect the patient's participation in the study
