Investigators

The overall officials registered on this study. Names that resolve to a findmyKOL profile link to it; the rest are shown as registered.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

2 registered facilities, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

United States
  • University of Colorado Cancer Center

    Aurora, Colorado, United States

  • Poudre Valley Hospital

    Fort Collins, Colorado, United States

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
