Primary efficacy endpoint for 80 mg (mean
change from baseline in AIMS dyskinesia total
score at Week 6)1
KINECT 3 was a phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel, fixed-dose study to evaluate the efficacy, safety, and tolerability of INGREZZA 40 mg and 80 mg, administered once daily, compared to placebo.2,a
The study included 234 medically stable patients with a clinical diagnosis of schizophrenia, schizoaffective disorder, or mood disorder with moderate to severe DRBA-induced TD: 66% (150/227) of patients had a primary psychiatric diagnosis of schizophrenia or schizoaffective disorder; 34% (77/227) of patients had mood disorder.2,4,b
Extension study (6 to 52 weeks)
The INGREZZA extension study evaluated the safety and tolerability of INGREZZA 40 mg and 80 mg, administered once daily.4
The 6-week DBPC study period was followed by a double-blind INGREZZA extension period for 42 weeks (total treatment period 48 weeks). At the end of Week 6 (end of the DBPC treatment period), patients were re-consented to confirm their willingness to continue in the study. Patients initially randomized to placebo were
