  1. How Trial Compass Is Solving Psychiatric Trial Enrollment 9/25/2025

    Psychiatric trials have long been among the most difficult to enroll. From treatment-resistant depression (TRD) and PTSD to cognitive and neuro disorders, sponsors are facing the same challenges over and over again:

    • Narrow I/E criteria that don’t translate into real-world patients
    • Sites with limited behavioral health infrastructure
    • Lack of patient trust and trial awareness in psychiatric populations
    • Professional patients
    • Rating scales aren’t used in clinical practices

    But what if recruitment didn’t have to start with a gamble?
