A Study of Dazostinag as Single Agent and Dazostinag in Combination With Pembrolizumab in Adults With Advanced or Metastatic Solid Tumors
NCT04420884 · View on ClinicalTrials.gov ↗
Study Summary
The main aim of this study is to check if people with advanced solid tumors have side effects from dazostinag, and to check how much dazostinag they can receive without getting significant side effects from it when given alone and in combination with pembrolizumab. The study will be conducted in two phases including a dose escalation phase and a dose expansion phase. In the dose escalation phase, escalating doses of dazostinag are being tested alone and in combination with pembrolizumab to treat participants who have advanced or metastatic solid tumors. In the dose expansion phase, dazostinag will be studied with pembrolizumab with or without chemotherapy in participants with untreated metastatic or recurrent, unresectable squamous cell carcinoma of head and neck (SCCHN) and in combination with pembrolizumab in third-line or later recurrent locally advanced or metastatic microsatellite instability-high/mismatch repair deficient (MSI-H/dMMR) and third-line recurrent locally advanced or metastatic microsatellite stable/mismatch repair proficient (MSS/pMMR) colorectal cancer (CRC).

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04420884
The ClinicalTrials.gov registry entry for NCT04420884 describes a study currently listed as active not 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 248 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Takeda, which has 387 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 Solid Neoplasms appearing as the primary indexed condition, and to 4 interventions — of which Pembrolizumab 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: NCT04420884 reports 20 study locations spanning 10 distinct geographic areas — top geographies include Missouri, California, Ohio. 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.
