Investigator Initiated Trials

ACADIA is committed to supporting investigator initiated trials (IIT) with the goal of improving patient’s health and quality of life by increasing the medical and scientific knowledge around pimavanserin. An IIT may be a clinical or non-clinical study for which ACADIA provides funding, drug product, or both. For clinical studies, our particular focus is research in trials which evaluate outcomes in adult patients with central nervous system disorders treated with pimavanserin. Requests outside of this area will not be considered. We support programs that will:

  • Contribute knowledge to the medical and scientific community;
  • Address unmet needs; and
  • Be communicated in an appropriate scientific forum, including peer-reviewed publications.

Examples of appropriate requestors of IIT support include, but are not limited to:

  • Healthcare providers
  • Members of the scientific community
  • Healthcare institutions
  • Colleges and universities
  • Government research institutions
