Borderline personality disorder: what the trials found

Quetiapine extended-release has demonstrated a statistically significant reduction in the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD) scores 5.

Brexpiprazole was evaluated in Phase 3 and Phase 2 trials; however, results did not reach statistical significance on the ZAN-BPD scale 7, nor were significant changes observed in the Clinical Global Impression - Severity of Illness (CGI-S) or Patient's Global Impression of Severity (PGI-S) scales 7. Safety assessments for Brexpiprazole showed no significant changes in Simpson-Angus Scale (SAS), Abnormal Involuntary Movement Scale (AIMS), or Barnes Akathisia Rating Scale (BARS) scores 6.

Recent results — preliminary, needs further review

  • Vafidemstat demonstrated a statistically significant reduction in the BEST-Total Score from baseline to the average of weeks 8 to 12 1.
  • Caplyta was evaluated in a Phase 2 trial, but no outcome data were provided 2.

For the clinician treating this condition

  • Quetiapine extended-release is supported by evidence showing significant improvement on the ZAN-BPD scale.
  • Brexpiprazole showed no statistically significant improvements in primary personality disorder scales (ZAN-BPD) or global severity measures (CGI-S, PGI-S).
