A Study of Zilovertamab Vedotin (MK-2140) in Combination With Cyclophosphamide, Doxorubicin, and Prednisone Plus Rituximab or Rituximab Biosimilar (Truxima) (R-CHP) in Participants With Diffuse Large B-Cell Lymphoma (DLBCL) (MK-2140-007)

Registration Number
NCT05406401
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This study consists of a dose escalation/confirmation phase and an efficacy expansion phase. The dose escalation/confirmation phase is to determine the safety and tolerability and establish a preliminary recommended Phase 2 dose (RP2D) of zilovertamab vedotin when administered in combination with R-CHP in participants with DLBCL who have received no prior treatment for their disease. The efficacy expansion phase is to determine the efficacy of the RP2D of zilovertamab vedotin when administered in combination with R-CHP in participants with DLBCL who have received no prior treatment for their disease.

Primary Outcome Measures
NameTimeMethod
Number of Participants Who Experienced Dose-limiting Toxicities (DLTs) in Cycle 1Cycle 1 (up to 21 days)

DLTs will be evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 and are defined as any drug-related adverse event (AE) observed during the DLT evaluation period (e.g. Cycle 1) that results in a change to a given dose or a delay in initiating the next cycle. The number of participants with DLTs in Cycle 1 will be reported.

Number of Participants Who Experienced At Least One AEUp to approximately 8 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who experience an AE will be reported.

Number of Participants Who Discontinued Study Treatment Due to an AEUp to approximately 5.5 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who discontinue study treatment due to an AE will be reported.

Complete Response Rate (CRR) per Lugano Response CriteriaUp to approximately 60 months

CRR is defined as the percentage of participants who achieve a Complete Response (CR) per Lugano response criteria \[Cheson, B. D., et al 2014\] for malignant lymphoma as assessed by the investigator. Assessment includes anatomic imaging with computed tomography (CT) or magnetic resonance imaging (MRI), metabolic imaging with positron emission tomography (PET), and clinical findings including physical examination and bone marrow biopsy results. The percentage of participants with CRR will be reported.

Secondary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR) per Lugano Response CriteriaUp to approximately 60 months

ORR is defined as the percentage of participants who achieve a CR or PR per Lugano response criteria \[Cheson, B. D., et al 2014\] for malignant lymphoma as assessed by the investigator. Assessment includes anatomic imaging with CT or MRI, metabolic imaging with PET, and clinical findings including physical examination and bone marrow biopsy results. The percentage of participants with ORR will be reported.

Duration of Response (DOR) per Lugano Response CriteriaUp to approximately 60 months

For participants who demonstrate a confirmed CR or PR per Lugano response criteria \[Cheson, B. D., et al 2014\] for malignant lymphoma, DOR is defined as the time from the first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first. CR and PR assessment includes anatomic imaging with CT or MRI, metabolic imaging with PET, and clinical findings including physical examination and bone marrow biopsy results. DOR as assessed by the investigator will be reported.
