Psychomotor and cognitive effects of a single oral dose of talnetant (SB223412) in healthy volunteers compared with placebo or haloperidol
Central Nervous System ( CNS ) effects of talnetant , an NK-3 antagonist in development for schizophrenia , were compared to those of haloperidol and placebo . The study was r and omised , double-blind , three-way crossover of talnetant 200 mg , haloperidol 3 mg or placebo .  Twelve healthy males participated  and EEG , saccadic and smooth pursuit eye movements , adaptive tracking , body sway , finger tapping , hormones , visual analogue scales ( VAS ) for alertness , mood and calmness and psychedelic effects , left/right distraction task , Tower of London and Visual and Verbal Learning Task were assessed . Haloperidol showed ( difference to placebo ; 95 % CI ; p-value ) decreases in EEG α power ( −0.87μV ; −1.51/−0.22 ; p = 0.0110 ) , saccadic inaccuracy ( 2.0 % ; 0.5/3.6 ; p = 0.0133 ) , smooth pursuit eye movements ( −7.5 % ; −12.0/−3.0 ; p = 0.0026 ) , adaptive tracking ( −3.5 % ; −5.4/−1.7 ; p = 0.0009 ) , alertness ( −6.8 mm ; −11.1/−2.4 ; p = 0.0039 ) , negative mood ( −4.6 mm ; −8.6/−0.6 ; p = 0.0266 ) , the ability to control thoughts ( 1.2 mm ; 0.2/2.3 ; p = 0.0214 ) , and an increase of serum prolactin ( ratio 4.1 ; 3.0/5.6 ; p < 0.0001 ) . Talnetant  showed decreased alpha power ( −0.69 μV ; −1.34/−0.04 ; p = 0.0390 ) , improved adaptive tracking ( 1.9 % ; 0.1/3.7 ; p = 0.0370 ) and reduced calmness on VAS Bond and Lader ( −4.5 mm ; −8.0/−1.0 ; p = 0.0151 ) . Haloperidol effects were predominantly CNS-depressant , while those of talnetant were slightly stimulatory . The results suggest that talnetant penetrates the brain , but it remains to be established whether this dose is sufficient and whether the observed effect profile is class-specific for NK3-antagonists
