A Study of Therapeutic Drug Monitoring-Based Atezolizumab Dosing
NCT06066138 · View on ClinicalTrials.gov ↗
Study Summary
Background: A type of drug called monoclonal antibody immune checkpoint inhibitors are often used in cancer treatment. These drugs help the body s immune system fight cancer by blocking proteins that cause cancer cells to grow. One of these drugs (atezolizumab) is approved to treat certain cancers. Researchers want to find out if lower doses of this drug might provide the same benefit with fewer adverse effects. Objective: To test different doses and timing of atezolizumab for people with cancer. Eligibility: People aged 18 years and older with cancer that has spread locally or to other organs. They must be eligible for treatment with the study drug. Design: Participants will be screened. They will have blood tests and imaging scans. They will provide a sample of tissue from their tumor. Atezolizumab is administered through a tube attached to a needle inserted into a vein in the arm. Participants will take this drug alone or combined with other drugs prescribed for their care. The first 2 treatments will be done per the FDA recommended dose and schedule. Before administering the second dose of the study drug, researchers will check the level of the drug in the participant s blood. Depending on those results, their 3rd dose will be scheduled 2 to 6 weeks later. For the 3rd dose of the study drug, participants will switch to the FDA minimum dosage. Dosages of any other drugs will not change. Researchers will continue to test the levels of the drug in participants blood before each treatment for 16 weeks. After that, these levels will be tested every 3 months. Study treatment may last up to 2 years....

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06066138
The ClinicalTrials.gov registry entry for NCT06066138 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 30 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 10 conditions, with Metastatic Melanoma appearing as the primary indexed condition, and to 1 intervention — of which Atezolizumab 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: NCT06066138 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.
