Pembrolizumab Plus CA-4948 for the Treatment of Patients With Progressive Metastatic Urothelial Cancer Despite Prior Immunotherapy
NCT06439836 · View on ClinicalTrials.gov ↗
Study Summary
This phase I trial tests the safety, side effects, best dose, and effectiveness of emavusertib (CA-4948) in combination with pembrolizumab in treating patients with urothelial cancer that has spread from where it first started to other places in the body (metastatic) and that has a resistance to PD-1/PD-L1 immune checkpoint inhibitors. CA-4948, a kinase inhibitor, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving CA-4948 in combination with pembrolizumab may be safe, tolerable and/or effective in treating patients with metastatic urothelial cancer that is resistant to PD-1/PD-L1 immune checkpoint inhibitors.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06439836
The ClinicalTrials.gov registry entry for NCT06439836 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 27 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 2 conditions, with Metastatic Urothelial Carcinoma appearing as the primary indexed condition, and to 5 interventions — of which Biospecimen Collection 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: NCT06439836 reports 11 study locations spanning 5 distinct geographic areas — top geographies include California, Georgia, New York. 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.
