TAEK-VAC-HerBy Vaccine for Brachyury and HER2 Expressing Cancer
NCT04246671 · View on ClinicalTrials.gov ↗
Study Summary
A Phase 1 open label trial of intravenous administration of TAEK-VAC-HerBy vaccine in patients with advanced brachyury and/or HER2- expressing cancer. The study will be completed in 2 stages. In Stage 1 patients will be enrolled and treated according to a 3+3 dose escalation scheme. Up to 4 dose levels will be explored to determine the recommended dose of TAEK-VAC-HerBy for Stage 2 of the trial. Stage 2 will enroll either chordoma patients for treatment with TAEK-VAC-HerBy alone, or HER2- positive breast cancer patients for combination treatment of TAEK-VAC-HerBy vaccine and therapeutic HER2 antibodies (trastuzumab). Patients in both stages will receive TAEK-VAC-HerBy intravenously, every three weeks, three administrations in total.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04246671
The ClinicalTrials.gov registry entry for NCT04246671 describes a study currently listed as completed. 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 37 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Bavarian Nordic, which has 16 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with HER2-positive Breast Cancer appearing as the primary indexed condition, and to 1 intervention — of which TAEK-VAC-HerBy 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: NCT04246671 reports 9 study locations spanning 8 distinct geographic areas — top geographies include Florida, Arizona, California. 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.
