This Study is Assessing the Safety and Efficacy of Immune Inhibition as a Treatment to Prevent Primary Graft Dysfunction
NCT06853223 · View on ClinicalTrials.gov ↗
Study Summary
Lung transplant recipient survival lags other solid organ recipients, with the main early cause of death being primary graft dysfunction (PGD). PGD occurs in up to 1/3 of all recipients, is driven by the body's innate immune response, and has no known medical therapies for treatment or prevention. Investigators have recently shown that Natural Killer (NK) cells, a key innate immune cell, are critical in causing PGD. Importantly, the investigators found that Maraviroc, an FDA-approved drug that works to inhibit these immune cells, prevented lung injury in mouse models of PGD. The goal of this clinical trial is to learn if Maraviroc works to treat PGD in Lung Transplant patients who are above the age of 18 and have a PGD risk score greater than 50%. The objectives the study hopes to address are: To address the safety and tolerability of Maraviroc. To test a strategy for PGD enrichment in a lung transplant population. To measure the efficacy and biological efficacy of using Maraviroc. To study the biochemical, physiologic, and molecular effects of the drug on the body. This will be a double blind study where patients will either get the Maraviroc drug or a placebo. Researchers will then compare the two groups to address the above objectives. Participants will: Take drug Maraviroc or a placebo every 12 hours for 3 days post surgery. Follow up will occur during the entire length of stay at UCSF, about 16 days, with a single 12 month follow up once released.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06853223
The ClinicalTrials.gov registry entry for NCT06853223 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 120 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of California, San Francis, which has 1,574 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, with Lung Transplantation appearing as the primary indexed condition, and to 2 interventions — of which Placebo 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: NCT06853223 reports 1 study location spanning 1 distinct geographic area — top geographies include 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.
