COMPLETED Early Phase 1

NT-I7, a Long-Acting Recombinant IL-7 Molecule, as an Immune Reconstitution Strategy for Lymphopenia in Patients With Progressive Multifocal Leukoencephalopathy

NCT04781309 · View on ClinicalTrials.gov ↗

Study Summary

Background: Progressive multifocal leukoencephalopathy (PML) is a brain infection. It is caused by a virus. PML can happen in people with a weakened immune system. PML is associated with cognitive and visual impairment as well as motor and speech disturbances. There is no treatment for PML. Researchers want to see if a new drug can help. Objective: To see if the drug NT-I7 can help increase lymphocyte numbers, which may help control PML infection. Eligibility: Adults ages 18 and older with PML who are enrolled in Protocol #13-N-0017. Design: Participants will be screened under Protocol #13-N-0017. Participants will have a 7-day inpatient stay, outpatient visits, and follow-up phone calls. Participants will have a medical history and physical exam. They will give urine samples. Blood will be drawn from an arm vein or through an intravenous (IV) catheter. Participants will get up to 3 doses of NT-I7. It will be given by injection into the muscle. Participants will have lumbar punctures ( spinal taps ). A thin needle will be inserted into the spinal canal in the lower back. Cerebrospinal fluid will be removed. X-ray may be used to guide the procedure. Participants will have magnetic resonance imaging (MRI) of the brain. The MRI scanner is a metal cylinder surrounded by a magnetic field. During MRIs, participants will lie on a table that slides in and out of the scanner. Soft padding or a coil will be placed around their head. They will get gadolinium, a contrast agent, through an IV catheter. Participation will last for 12 to 19 months. ...

What the Registry Record Tells You About NCT04781309

The ClinicalTrials.gov registry entry for NCT04781309 describes a study currently listed as completed. It is categorized as Early 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 12 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Neurological Disorders and Stroke (NINDS), which has 339 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 Progressive Multifocal Leukoencephalopathy appearing as the primary indexed condition, and to 1 intervention — of which NT-I7 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: NCT04781309 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. 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.
