NCT06833866 · View on ClinicalTrials.gov ↗
Study Summary
This is a phase I study investigating the safety and antitumor activity of 5FU-based therapy (FOLFIRI/FOLFOX + Biologics) in combination with Hydroxytyrosol (HT) as a treatment for patients with advanced or metastatic colorectal cancer. Patients will receive: 1 capsule of HT 25 mg daily for 2 weeks before beginning 5FU-based therapy (FOLFIRI/FOLFOX + Biologics), 1 capsule of HT (25 mg) daily for 2 weeks while receiving the FOLFIRI/FOLFOX + Biologics, until sign of disease progression. The prescribed FOLFIRI/FOLFOX administer as: Irinotecan 180 mg/m² intravenously (IV) over 90 minutes concurrently with Leucovorin 400 mg/m² IV over 120 minutes, followed by Fluorouracil 400-500 mg/m² IV bolus then 2400-3000 mg/m² IV infusion over 4-6 hours with or without, the designated Biologics, a standard dose of Cetuximab or Bevacizumab will be administered in 2-week cycles until disease progression or un-tolerated toxicity

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06833866
The ClinicalTrials.gov registry entry for NCT06833866 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 33 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is The Methodist Hospital Research Institute, which has 203 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 Advanced or Metastatic CRC appearing as the primary indexed condition, and to 1 intervention — of which Hydroxytyrosol 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: NCT06833866 reports 1 study location spanning 1 distinct geographic area — top geographies include 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.
