A Study to Learn How [14C]ASP0367 is Processed by the Body in Healthy Men
NCT05217901 · View on ClinicalTrials.gov ↗
Study Summary
ASP0367 is a potential new treatment for people with Duchenne Muscular Dystrophy and Mitochondrial Myopathies. Before ASP0367 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This study is in healthy men. The main aim of this study is to learn how ASP0367 is processed by and acts upon the bodies of healthy men. To do this, \[14C\] which is a certain chemical (called a tracer, or radionuclide) has been added to ASP0367. \[14C\] gives off radiation, but the dose is very low (about the same as the dose from an x-ray) and will leave the body within a few days. \[14C\] will be picked up by a scanner and will be used to follow ASP0367 through the body. \[14C\]ASP0367 will be a liquid. During the study, the men who take part will stay in the clinic for 6 days and 5 nights. Some men may need to stay up to an extra 7 days in the clinic. This will happen if there is a medical reason or if they still have traces of radiation in their blood, urine or feces. On the day before they drink \[14C\]ASP0367, the men will be asked about their medical history, have a medical examination, and have their vital signs checked (blood pressure and pulse). They will also have an ECG to check their heart rhythm. They will give urine, stool and blood samples for laboratory tests. They will also be asked if they have had any medical problems. The men will fast for 10 hours or more before drinking \[14C\]ASP0367 and for 4 hours afterwards. They will only have one drink of \[14C\]ASP0367. They will need to lie still for 4 hours after drinking \[14C\]ASP0367. They will have their vital signs checked and give urine, stool and blood samples for laboratory tests. Then, they will give urine, stool and blood samples every day until they leave the clinic. They will also be asked every day if they have had any medical problems. The day after they drink \[14C\]ASP0367, the men will also have an ECG. On the last clinic day, the men will also h

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05217901
The ClinicalTrials.gov registry entry for NCT05217901 describes a study currently listed as completed. 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 9 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Astellas Pharma Global Development, which has 172 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 Healthy Volunteers appearing as the primary indexed condition, and to 1 intervention — of which 14C-labeled ASP0367 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: NCT05217901 reports 1 study location spanning 1 distinct geographic area — top geographies include Wisconsin. 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.
