ACTIVE NOT RECRUITING Phase 3

Safety and Immunogenicity of Extended 2-dose Regimens of 9-valent Human Papillomavirus (9vHPV) Vaccine (V503-069)

NCT04708041 · View on ClinicalTrials.gov ↗

Study Summary

This is a 96-month safety and immunogenicity study conducted in boys and girls 9 to 14 years of age and in young women 16 to 26 years of age. From this study, the goal is to establish that the investigational extended 2-dose regimens (0, 12 months; 0, 24 months; 0, 36 months; and 0, 60 months) studied in boys and girls 9 to 14 years of age are generally safe and immunogenic, with an antibody response that is not inferior to that observed in young women 16 to 26 years of age who receive the standard 3-dose regimen of 9-valent human papillomavirus (9vHPV) vaccine at 0, 2, and 6 months (i.e., the population and dose regimen used to establish 9vHPV vaccine efficacy).

What the Registry Record Tells You About NCT04708041

The ClinicalTrials.gov registry entry for NCT04708041 describes a study currently listed as active not recruiting. 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 700 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Merck Sharp & Dohme, which has 741 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 Papillomavirus Infections appearing as the primary indexed condition, and to 1 intervention — of which 9vHPV vaccine 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: NCT04708041 reports 20 study locations spanning 11 distinct geographic areas — top geographies include California, South Carolina, Texas. 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.
