{Abstract}: The effects of masupirdine on the neuropsychiatric symptoms were explored.<BR>Masupirdine (SUVN-502) was evaluated for its effects on cognition in patients with moderate AD. The prespecified primary outcome showed no drug-placebo difference. Post hoc analyses of domains of the 12-item neuropsychiatric inventory scale were carried out.<BR>In a subgroup of patients (placebo, n = 57; masupirdine 50 mg, n = 53; masupirdine 100 mg, n = 48) with baseline agitation/aggression symptoms ≥1, a statistically significant reduction in agitation/aggression scores was observed in masupirdine 50 mg (95% confidence interval (CI), -1.9 to -0.5, p < 0.001) and masupirdine 100 mg (95% CI, -1.7 to -0.3, p = 0.007) treated arms at Week 13 in comparison to placebo and the effect was sustained for trial duration of 26 weeks in the masupirdine 50 mg treatment arm (95% CI, -2.3 to -0.8, p < 0.001). Similar observations were noted in the subgroup of patients (placebo, n = 29; masupirdine 50 mg, n = 30; masupirdine 100 mg, n = 21) with baseline agitation/aggression symptoms ≥3. In the subgroup of patients (placebo, n = 28; masupirdine 50 mg, n = 28; masupirdine 100 mg, n = 28) who had baseline psychosis symptoms and/or symptom emergence, a significant reduction in psychosis scores was observed in the masupirdine 50 mg (Week 4: 95% CI, -2.8 to -1.4, p < 0.001; Week 13: 95% CI, -3.3 to -1.3, p < 0.001) and masupirdine 100 mg (Week 4: 95% CI, -1.4 to 0, p = 0.046; Week 13: 95% CI, -1.9 to 0.1, p = 0.073) treatment arms in comparison to placebo.<BR>Further research is warranted to explore the potential beneficial effects of masupirdine on NPS.
