177Lu-PSMA-617 vs. Androgen Receptor-Directed Therapy in the Treatment of Progressive Metastatic Castrate Resistant Prostate Cancer
NCT04689828 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to determine whether 177Lu-PSMA-617 improves the Radiographic progression-free survival (rPFS) or Overall Survival (OS) compared to a change in Androgen receptor-directed therapy (ARDT) in metastatic castrate resistant prostate cancer (mCRPC) participants that were previously treated with an alternate ARDT and not exposed to a taxane-containing regimen in the CRPC or mHSPC settings. 469 participants were randomized (235 in the 177Lu-PSMA-617 group and 234 in the ARDT group.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04689828
The ClinicalTrials.gov registry entry for NCT04689828 describes a study currently listed as active not recruiting. It is categorized as Phase 3, 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 469 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Novartis Pharmaceuticals, which has 792 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 Prostatic Neoplasms appearing as the primary indexed condition, and to 3 interventions — of which 68Ga-PSMA-11 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: NCT04689828 reports 20 study locations spanning 15 distinct geographic areas — top geographies include New York, Massachusetts, Nebraska. 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.
