Study Summary
The investigator would like to see if aspirin could block niacin-induced flushing by analyzing blood and urine after taking aspirin. Phase I: Subjects were assigned to either placebo or aspirin groups. They were given 5 days of 81 mg aspirin or placebo. On day 5, they were given a single dose of niacin (600 mg) administered 30 minutes after the last dose of aspirin or placebo. The same subjects came back for cross-over study and were assigned to a different group. There was a 2-week washout period between each treatment. Urine was collected sequentially for analysis Phase II: The same study subjects come back for an open label one week study. They were given 5 days of taking 81 mg Aspirin, taken once daily, followed by a single dose of 600 mg Niacin on day 6. Urine was collected sequentially for analysis

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01275300
The ClinicalTrials.gov registry entry for NCT01275300 describes a study currently listed as completed. It is categorized as NA, 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 University of Pennsylvania, which has 1,457 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 Hyperlipidemia appearing as the primary indexed condition, and to 3 interventions — of which Placebo 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: NCT01275300 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. 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.
