In the open-label PRISM II trial (N=367), the primary endpoint was change from baseline to Day 90 in CNS-LS score
- CNS-LS score in all cohorts combined was 20.4 at baseline to 12.8 at Day 90 (P<0.001 vs baseline)
- CNS-LS reductions were similar across all 3 disease cohorts (dementia, stroke, and TBI) with a range of 7.2 to 8.5 at Day 90
SECONDARY ENDPOINT: MEDIAN REDUCTION FROM BASELINE IN NUMBER OF PBA EPISODES/WEEKa,1

aMedian episode count is depicted as it is resistant to outliers, unlike the mean.
- 20.4% (n=75) of participants were aged 75 or older2
- 82% of patients were living at home2
GLOBAL IMPROVEMENT AND SATISFACTION RATING AT DAY 90 (SECONDARY OUTCOMES)a,2

PGICc
72.4%
of patients were Much Improved or Very Much Improved with respect
to PBAb

CGICc

bCaregivers completed the rating when the patient was not able to do so.2
cUsing the Patient Global Impression of Change (PGIC) and Clinical Global Impression of Change (CGIC) scales, patients/clinicians were asked, “Rate the total impression of change in your/your patient’s condition (with respect to PBA) from the time of study admission to the present (end of study).” PGIC reported: 32.6% Very Much Improved; 39.8% Much Improved; 18.8% Minimally Improved; 8% No Change; 0.4% Minimally Worse; 0.4% Much Worse. CGIC reported: 33.7% Very Much Improved; 42.9% Much Improved; 13.4% Minimally Improved; 8.8% No Change; 0.8% Minimally Worse; 0.4% Much Worse. No patients/clinicians reported Very Much Worse.2
dPatients/caregivers were asked, “How satisfied are you with NUEDEXTA as a treatment for your PBA?” Reported: 47.5% Very Satisfied; 28% Somewhat Satisfied; 11.5% Neither Satisfied nor Dissatisfied; 5.4% Somewhat Dissatisfied; 7.7% Very Dissatisfied.2
PRISM ll, 90-day, open-label (uncontrolled), 74-site US trial in adult patients with dementia, stroke, or TBI. All patients had a clinical diagnosis of PBA and a CNS-LS score ≥13 at baseline. Patients received 1 capsule of NUEDEXTA QD during Week 1 and were titrated to 1 capsule Q12H for Weeks 2 through 12. The primary endpoint was change from baseline in CNS-LS score. Effectiveness population: Dementia: Baseline n=108, Day 30 n=108, Day 90 n=102. Stroke: Baseline n=103, Day 30 n=103, Day 90 n=92. TBI: Baseline n=87, Day 30 n=86, Day 90 n=67. Overall: Baseline n=298, Day 30 n=297, Day 90 n=261.1,2
