Pembrolizumab, Lenvatinib and IL-15 Superagonist N-803 in Combination With HER2 Targeting Autologous Dendritic Cell (AdHER2DC) Vaccine in Participants With Advanced or Metastatic Endometrial Cancer
NCT06253494 · View on ClinicalTrials.gov ↗
Study Summary
Background: Endometrial cancer (EC) of the uterus is becoming more common in the US. Sometimes EC often has increased levels of a protein called HER2. Cancers with HER2 tend to be more aggressive and have poorer outcomes. Objective: To test 2 study drugs-a vaccine that targets HER2 (AdHER2DC) plus a drug that supercharges immune cells that kill tumor cells (N-803)-combined with 2 FDA-approved cancer treatment drugs in people with EC. Eligibility: Adults aged 18 and older with HER2-positive EC that returned or got worse after treatment. Design: AdHER2DC vaccine is made from each participant s own blood. Participants will undergo apheresis: Blood is removed from the body through a tube attached to a needle. The blood passes through a machine that separates out the target cells. The remaining blood is returned to the body through a second needle. A special catheter may be needed. The first treatment cycle is 28 days; each cycle after that will be 21 days. All participants will get the 2 approved drugs and the vaccine. One drug is a tablet taken by mouth once a day, every day. The other drug is given through a tube attached to a needle inserted into a vein. The vaccine is injected under the skin. Participants will receive the vaccine on day 1 of cycles 1, 2, and 3. Additional doses up to 3 doses will be give if possible. Some participants will receive N-803. This drug is injected under the skin of the abdomen on day 1 of each cycle. Treatment may last up to 1 year. Follow-up visits will continue up to 2 more years.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06253494
The ClinicalTrials.gov registry entry for NCT06253494 describes a study currently listed as recruiting. It is categorized as Phase 1, 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 60 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Cancer Institute (NCI), which has 2,390 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, 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: NCT06253494 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. 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.
