hCAP18 Levels and Vitamin D Deficiency in Healthy Subjects
NCT00742235 · View on ClinicalTrials.gov ↗
Study Summary
Vitamin D deficiency (low levels of vitamin D in the blood) is a common problem. A recently discovered protein, called hCAP18, likely plays an important role in the immune system and may depend on adequate levels of vitamin D. It is not known what levels of vitamin D are needed to allow the body to make this protein. Nor is it known if giving vitamin D to people who are found to be deficient will help boost levels of hCAP18. This study aims to clarify the relationship between vitamin D levels and hCAP18.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00742235
The ClinicalTrials.gov registry entry for NCT00742235 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 99 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Massachusetts General Hospital, which has 1,948 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Healthy Subjects appearing as the primary indexed condition, and to 1 intervention — of which ergocalciferol 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: NCT00742235 reports 1 study location spanning 1 distinct geographic area — top geographies include Massachusetts. 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. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
