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)

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 Criteria:

The main inclusion criteria include but are not limited to the following:

* Has histologically confirmed diagnosis of germinal center B-cell (GCB) subtype of diffuse large B-cell lymphoma (DLBCL), by prior biopsy, according to the World Health Organization (WHO) classification of neoplasms of the hematopoietic and lymphoid tissues.
* Has positron emission tomography (PET) positive disease at screening, defined as 4 to 5 on the Lugano 5-point scale.
* 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.

Exclusion Criteria:

The main exclusion criteria include but are not limited to the following:

* Has a history of transformation of indolent disease to DLBCL.
* Has received a diagnosis of primary mediastinal B-cell lymphoma (PMBCL) or Grey zone lymphoma.
* Has Ann Arbor Stage I DLBCL.
* Has clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (\<6 months prior to enrollment), myocardial infarction (\<6 months prior to enrollment), unstable angina, congestive heart failure (New York Heart Association Classification Class ≥II), or serious cardiac arrhythmia requiring medication.
* Has clinically significant pericardial or pleural effusion.
* Has ongoing Grade \>1 peripheral neuropathy.
* Has a demyelinating form of Charcot-Marie-Tooth disease.
* HIV-infected participants with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease.
* Has ongoing corticosteroid therapy.
* Known additional malignancy that is progressing or has required active treatment within the past 2 years.
* Known active central nervous system (CNS) lymphoma.
* Has active autoimmune disease that has required systemic treatment in the past 2 years.
* Has active infection requiring systemic therapy.
* Has active HBV (defined as HBsAg positive and detectable HBV deoxyribonucleic acid (DNA)) and HCV (defined as anti-HCV antibody positive and detectable HCV ribonucleic acid (RNA)) infection.
* Has history of stem cell/solid organ transplant.
