About Trop-2

Trop-2, or Tumor-associated calcium signal transducer 2, is a transmembrane glycoprotein often overexpressed in various cancer cells. Its overexpression makes it an attractive target for antibody-drug conjugates (ADCs) that deliver cytotoxic payloads directly to tumor cells.

Trop-2 requires biologic approaches (adc), likely due to its structure or location.

The exclusive focus on ADCs suggests a whitespace opportunity for novel modalities targeting Trop-2.

How We Count Trials

  • Trials: phase 1-4 interventional trials on ClinicalTrials.gov that started in 2008 or later and test an FDA-approved drug acting on Trop-2. A trial counts if an approved drug acting on Trop-2 is in any arm, including as a comparator, and a trial that tests two such drugs counts once. Trials that test only unapproved drugs are not counted. A trial listed as phase 1/2 counts as phase 1, and phase 2/3 as phase 2.
  • Active: recruiting, not yet recruiting, enrolling by invitation, or active and no longer recruiting.
  • Completion rate: of the trials that have ended, the share marked Completed rather than Terminated or Withdrawn. Completed means the trial ended as planned; it does not mean the drug worked. Suspended trials are not counted as ended.
  • Stopped: terminated or withdrawn. Trials stop for many reasons, including slow enrolment and business decisions, not only safety or efficacy.
  • Sponsors: the lead sponsor of each trial. Companies are the sponsors ClinicalTrials.gov classes as industry; the rest are universities, hospitals, cooperative groups, government bodies and individuals.
