VIrtual STudy in Achondroplasia for the US (VISTA)
NCT06168201 · View on ClinicalTrials.gov ↗
Study Summary
This is an observational study of individuals with achondroplasia in the United States. The primary study population consists of pediatric individuals treated and untreated with VOXZOGO™. Study enrollment started in February 2023. The projected total duration of the study is approximately 5 years at minimum from start of study recruitment in February 2023, with the duration of individual prospective follow-up differing depending on the time of enrollment. The study duration may be extended based on decisions by the study sponsor. Data will be collected in two formats for the primary pediatric study population: 1. Participant-mediated access to electronic health records(including medical imaging, when available) which will enable retrospective and prospective collection of secondary data reflecting real-life treatment use and clinical care. . 2. Primary data collection of Clinical Outcome Assessments (COAs) and questionnaire data. Data will be collected in the following format for the adult cohort: \- Participant-mediated access to electronic health records (including medical imaging, when available) which will enable retrospective and prospective collection of secondary data reflecting real-life treatment use and clinical care. The primary study population will include approximately 150 pediatric individuals with achondroplasia regardless of their treatment status with VOXZOGO™. Individuals may change status from untreated to treated during the prospective period of the study (or vice versa) however they will only be counted once, based on their treated status at the point of enrollment. The secondary study population will include 20 adolescent and adult participants.

The ClinicalTrials.gov registry entry for NCT06168201 describes a study currently listed as recruiting. It is categorized as an unspecified phase, 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 170 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is BioMarin Pharmaceutical, which has 31 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 Achondroplasia appearing as the primary indexed condition, and to 0 interventions. 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: NCT06168201 reports 7 study locations spanning 6 distinct geographic areas — top geographies include California, North Carolina, Ohio. 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.
