A Clinical Study of Zilovertamab Vedotin (MK-2140) Plus Rituximab Plus Cyclophosphamide, Doxorubicin, and Prednisone (R-CHP) Versus Polatuzumab Vedotin Plus R-CHP in People With Diffuse Large B-cell Lymphoma (DLBCL) (MK-2140-011/waveLINE-011)
A Randomized, Open-label, Multicenter, Phase 2 Study Evaluating the Efficacy and Safety of Zilovertamab Vedotin (MK-2140) Plus R-CHP Versus Polatuzumab Vedotin Plus R-CHP in Treatment-naïve Participants With GCB Subtype of Diffuse Large B-cell Lymphoma (DLBCL)

Conditions
Summary
Researchers are looking for ways to treat germinal center B-cell-like diffuse large B-cell lymphoma (GCB DLBCL). DLBCL is a fast-growing blood cancer that affects B-cells. GCB is a type of DLBCL that affects young B-cells that are still maturing. The goal of this study is to learn if more people who receive zilovertamab vedotin (MK-2140) and R-CHP have the cancer respond (go away) than those who receive polatuzumab vedotin and R-CHP.
Eligibility
Inclusion Criteria6

- Has received no prior treatment for their DLBCL.
- Human immunodeficiency virus (HIV) infected participants must have well controlled HIV on antiretroviral therapy (ART).
- Participants who are hepatitis B surface antigen (HBsAg) positive are eligible if they have received hepatitis B virus (HBV) antiviral therapy and have undetectable HBV viral load prior to randomization.
- Participants with history of hepatitis C virus (HCV) infection are eligible if HCV viral load is undetectable at screening.
