A Study to Compare Sacituzumab Tirumotecan (MK-2870) in Combination With Pembrolizumab (MK-3475) Versus Pembrolizumab Alone as Treatment in Participants With Mismatch Repair Proficient Endometrial Cancer (MK-2870-033/TroFuse-033/GOG-3119/ENGOT-en29)
NCT06952504 · View on ClinicalTrials.gov ↗
Study Summary
Researchers are looking for new ways to treat people with proficient mismatch repair (pMMR) endometrial cancer (EC) that is advanced or recurrent. * EC is a type of cancer that starts in the tissues inside the uterus (womb) * pMMR indicates that certain normal proteins are present in the cancer cells * Advanced means the cancer has spread locally or to other parts of the body (metastatic) and cannot be removed with surgery * Recurrent means the cancer came back after surgery Sacituzumab tirumotecan (also known as sac-TMT) and pembrolizumab are the study medicines. Sac-TMT is an antibody drug conjugate (ADC). An ADC attaches to specific targets on cancer cells and delivers treatment to destroy those cells. The goal of this study is to learn if people who receive sac-TMT with pembrolizumab live longer and without the cancer getting worse compared to people who receive pembrolizumab alone.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06952504
The ClinicalTrials.gov registry entry for NCT06952504 describes a study currently listed as recruiting. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 1,123 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Merck Sharp & Dohme, which has 741 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Endometrial Cancer appearing as the primary indexed condition, and to 5 interventions — of which Pembrolizumab is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06952504 reports 20 study locations spanning 13 distinct geographic areas — top geographies include Florida, California, Louisiana. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
