Panitumumab, Regorafenib, or TAS-102, in Treating Patients With Metastatic and/or Unresectable RAS Wild-Type Colorectal Cancer
NCT03992456 · View on ClinicalTrials.gov ↗
Study Summary
This phase II trial studies how well retreatment with panitumumab works compared to standard of care regorafenib or trifluridine and tipiracil hydrochloride (TAS-102) in treating patients with colorectal cancer that is negative for RAS wild-type colorectal cancer has spread to other places in the body (metastatic), and/or cannot be removed by surgery (unresectable), and is negative for resistance mutations in blood. Treatment with panitumumab may interfere with the ability of tumor cells to grow and spread. Some tumors need growth factors to keep growing. Growth factor antagonists, such as regorafenib, may interfere with the growth factor and stop the tumor from growing. Drugs used in chemotherapy, such as TAS-102, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving panitumumab may work better in treating patients with colorectal cancer than with the usual treatment of regorafenib or TAS-102.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03992456
The ClinicalTrials.gov registry entry for NCT03992456 describes a study currently listed as active not 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 12 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Academic and Community Cancer Research United, which has 21 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 10 conditions, with Metastatic Colorectal Carcinoma appearing as the primary indexed condition, and to 5 interventions — of which Quality-of-Life Assessment 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: NCT03992456 reports 18 study locations spanning 13 distinct geographic areas — top geographies include California, Massachusetts, District of Columbia. 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.
