A Study of Oseltamivir (Tamiflu) for Treatment of Influenza in Immunocompromised Participants.
NCT00545532 · View on ClinicalTrials.gov ↗
Study Summary
This 2-arm study will investigate the safety and tolerability of oseltamivir for the treatment of influenza in immunocompromised participants and characterize the effects of oseltamivir in immunocompromised participants on the development of resistant influenza virus. Eligible immunocompromised participants with laboratory-confirmed influenza will be randomized to receive either conventional dose (30 milligrams \[mg\] to 75 mg twice daily orally \[po\], depending on age and weight) or double dose (60 mg-150 mg twice daily po depending on age and weight) olseltamivir for 10 days. Nasal and throat swabs will be taken, and safety evaluations made, at intervals during the study. The anticipated time on study medication is 10 days and the anticipated time on study is 40 days.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00545532
The ClinicalTrials.gov registry entry for NCT00545532 describes a study currently listed as completed. It is categorized as Phase 3, 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 228 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Hoffmann-La Roche, which has 758 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 Influenza, Human appearing as the primary indexed condition, and to 2 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: NCT00545532 reports 20 study locations spanning 8 distinct geographic areas — top geographies include California, Florida, Georgia. 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.
