Trial Watch: A Study of Zilovertamab Vedotin (MK-2140) in Combination With Standard of Care in Participants With Relapsed or Refractory Diffuse Large B-Cell Lymphoma (rrDLBCL) (MK-2140-003)
Important context
- Trial eligibility (participation has strict criteria): Clinical-trial participation has study-specific eligibility criteria; registry listing does not mean a person qualifies or should enroll.
In plain English
The 30-second version
What happened?
ClinicalTrials.gov confirms that this Phase 3 study is registered and currently listed as Recruiting. This establishes the study's existence and registry-reported design/status, not a treatment benefit.
Why does it matter?
Phase 3 trials can contribute later-stage human evidence. CancerDiscoveries can track this record as results and regulatory information emerge.
What does this not prove?
A registered trial is not proof that the intervention works, is not FDA approval for this cancer or use, and is not a clinical-guideline recommendation.

What changed: ClinicalTrials.gov lists A Study of Zilovertamab Vedotin (MK-2140) in Combination With Standard of Care in Participants With Relapsed or Refractory Diffuse Large B-Cell Lymphoma (rrDLBCL) (MK-2140-003) (NCT05139017) as a Phase 3 interventional cancer study. The registry status is Recruiting, with the record last updated 2026-10-21.
Study snapshot: Phase 3; Recruiting; planned enrollment 290. Conditions listed: DLBCL, Diffuse Large B-Cell Lymphoma. A primary outcome listed by the registry is: Number of participants who experienced dose-limiting toxicities (DLTs) in Part 1.
This entry tracks verified trial-registry facts. Trial registration by itself does not show that an intervention is effective, safe for a particular person, FDA-approved for this use, or recommended by clinical guidelines.
Population / Applicability
Studied in: Participants age 18 Years and older with DLBCL, Diffuse Large B-Cell Lymphoma who meet the study-specific registry eligibility criteria. (Adults)
Eligibility is study-specific. Registry information does not determine whether any individual should enroll in or receive the intervention.
