NCT05437055: An overdue trial by Penumbra Inc.

This trial is overdue. It was due to report 2 months, 3 weeks ago.

Think we've made a mistake? Before contacting us, review the criteria in our paper. In particular, bear in mind the following:

  • We can only rely on the structured data that sponsors put into the registry: they may enter incorrect or incomplete data.
  • Reporting in a journal is not enough. The FDAAA rules state that the trial must be reported on ClinicalTrials.gov.
  • Terminated trials are required to report results. Only withdrawn trials (which never recruited a single patient) are not.
