Treatment of Participants With Primary or Secondary Progressive Multiple Sclerosis
NCT07477639 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this clinical trial is to treat male and female participants with two types of Multiple Sclerosis (MS) called primary progressive or secondary progressive MS. The main questions the trial aims to answer are the following: * Is TRX319 safe when administered to patients with progressive forms of MS? * At what dose does TRX319 work the best to treat participants with primary and or secondary progressive MS? * Is pre-conditioning (with Bendamustine) needed to allow TRX319 to better treat participants with primary and/or secondary progressive MS? Participants will be asked to be on study for up 1 year and may receive up to 3 total administrations of TRX319. While on study, participants will have blood tests and other assessments (MRI scans and lumbar punctures) done to understand the safety of TRX319 and how it may benefit their multiple sclerosis.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT07477639
The ClinicalTrials.gov registry entry for NCT07477639 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 39 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Tr1X, which has 3 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 5 conditions, with Multiple Sclerosis appearing as the primary indexed condition, and to 2 interventions — of which Bendamustine 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: NCT07477639 reports 2 study locations spanning 2 distinct geographic areas — top geographies include Kansas, Missouri. 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.
