Prediction of Neoadjuvant Chemotherapy Response Using Contrast-Enhanced Ultrasound in Patients With Locally Advanced Breast Cancer
NCT04715958 · View on ClinicalTrials.gov ↗
Study Summary
This phase II/III trial studies if contrast-enhanced ultrasounds using a contrast dye, perflutren lipid microspheres (Definity), can predict the response to chemotherapy by estimating the pressure in the cancer in patients with breast cancer that has spread to nearby tissues and lymph nodes (locally advanced). The efficacy of cancer therapy is affected by the pressure in the cancer. Definity is a contrast dye used to create better images during ultrasounds. The purpose of this trial is to determine if a special kind of ultrasound, called contrast-enhanced ultrasound, an experimental imaging test, can detect pressures in cancer to determine the response to neoadjuvant chemotherapy in patients with breast cancer.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04715958
The ClinicalTrials.gov registry entry for NCT04715958 describes a study currently listed as recruiting. It is categorized as Phase 2, 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 200 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Kibo Nam, which has 1 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 Anatomic Stage III Breast Cancer AJCC v8 appearing as the primary indexed condition, and to 3 interventions — of which Perflutren Lipid Microspheres 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: NCT04715958 reports 3 study locations spanning 3 distinct geographic areas — top geographies include Minnesota, Pennsylvania, Texas. 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.
