Study of INBRX-106 and INBRX-106 in Combination With Pembrolizumab (Keytruda®) in Subjects With Locally Advanced or Metastatic Solid Tumors (Hexavalent OX40 Agonist)
NCT04198766 · View on ClinicalTrials.gov ↗
Study Summary
This is a Phase 1/2, open-label, non-randomized, 4-part trial to determine the safety profile and identify the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of INBRX 106 administered as a single agent or in combination with the anti-PD-1 checkpoint inhibitor (CPI) pembrolizumab (Keytruda®). KEYTRUDA is a registered trademark of Merck Sharp \& Dohme LLC, a subsidiary of Merck \& Co., Inc., Rahway, NJ, USA.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04198766
The ClinicalTrials.gov registry entry for NCT04198766 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 296 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Inhibrx Biosciences, which has 4 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 7 conditions, with Melanoma appearing as the primary indexed condition, and to 5 interventions — of which INBRX-106 - Hexavalent OX40 agonist antibody 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: NCT04198766 reports 20 study locations spanning 11 distinct geographic areas — top geographies include California, Michigan, Florida. 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.
