Aripiprazole,an antipsychotic with a novel mechanism of action,and risperidone vs placebo in patients with schizophrenia and schizoaffective disorder

BACKGROUND: Aripiprazole is a dopamine D2 receptor partial agonist with partial agonist activity at serotonin 5HT1A receptors and antagonist activity at 5HT2A receptors. This multicenter trial examined the efficacy, safety, and tolerability of aripiprazole in patients with acute exacerbation of schizophrenia or schizoaffective disorder. METHODS: In this 4-week double-blind study, 404 patients were randomized to 20 mg/d (n = 101) or 30 mg/d (n = 101) of aripiprazole, placebo (n = 103), or 6 mg/d of risperidone (n = 99). Efficacy assessments included Positive and Negative Syndrome Scale (PANSS) scores and Clinical Global Impression scores. Safety and tolerability evaluations included extrapyramidal symptoms and effects on weight, prolactin, and corrected QT (QTc) interval. RESULTS: Aripiprazole (20 and 30 mg/d) and risperidone (6 mg/d) were significantly better than placebo on all efficacy measures. Separation from placebo occurred at week 1 for PANSS total and positive scores with aripiprazole and risperidone and for PANSS negative scores with aripiprazole. There were no significant differences between aripiprazole and placebo in mean change from baseline in the extrapyramidal symptom rating scales. Mean prolactin levels decreased with aripiprazole but significantly increased 5-fold with risperidone. Mean change in QTc interval did not differ significantly from placebo with any active treatment group. Aripiprazole and risperidone groups showed a similar low incidence of clinically significant weight gain. CONCLUSIONS: Aripiprazole is effective, safe, and well tolerated for the positive and negative symptoms in schizophrenia and schizoaffective disorder. It is the first non-D2 receptor antagonist with clear antipsychotic effects and represents a novel treatment development for psychotic disorders.     

多巴胺D3受体基因Ser9Gly多态性与阿立哌唑及利培酮治疗效应的关联研究

目的比较阿立哌唑与利培酮治疗女性首发精神分裂症患者的疗效和血浆催乳素水平变化及其与多巴胺D3受体(DRD3)基因Ser9Gly(rs6280)多态性的关联。方法选择完成8周阿立哌唑或利培酮治疗的女性首发精神分裂症患者各60例,于治疗前和治疗8周后分别评测阳性与阴性症状量表(positive and negativesymptom scale,PANSS)。采用放射免疫法检测血浆催乳素水平,DNA测序技术检测DRD3基因Ser9Gly多态性,分析DRD3基因Ser9Gly多态性与两药疗效及血浆催乳素变化的关联。结果治疗8周后,两组PANSS减分率的差异无统计学意义[(59.79±23.48)vs.(63.30±22.66),P>0.05],但利培酮组血浆催乳素的变化值高于阿立哌唑组[(26.92±9.48)vs.(-25.25±8.07),P<0.05]。利培酮组中C等位基因携带者的血浆催乳素的增加明显高于未携带者[(52.48±27.01)ng/mL vs(36.07±17.46),P<0.05];而阿立哌唑组中未见此差异[(-23.27±8.36)vs.TT(-26.05±8.11),P>0.05]。两组8周后PANSS减分率(%)与DRD3基因Ser9Gly的差异均无统计学意义:阿立哌唑组[CC+CT(57.83±19.94)vs.TT(56.84±18.46),P>0.05];利培酮组[CC+CT(53.94±21.08)vs.TT(60.38±19.37),P>0.05]。结论阿立哌唑治疗女性首发精神分裂症疗效与利培酮相当,但引起血浆催乳素水平变化的幅度较小;利培酮引起血浆催乳素水平增加可能与DRD3基因Ser9Gly多态性有关联。

Risperidone in the treatment of elderly patients with psychotic disorders.

The authors evaluated the safety, tolerability, and efficacy of risperidone in 103 elderly patients (mean age, 71 years) with schizophrenia (75%) or schizoaffective disorder (25%). Using the Extrapyramidal Symptoms Rating Scale (ESRS), Positive and Negative Syndrome Scale (PANSS), and Clinical Global Impression (CGI) scale, they conducted a prospective, open-label, 12-week trial in 14 psychiatric centers in the United States. Patients' symptoms were assessed at baseline and over a 12-week period. At endpoint, ESRS scores were significantly reduced, as were PANSS total and subscale scores. There were no clinically significant changes in electrocardiograms, laboratory test results, or vital signs. Risperidone was well tolerated and efficacious in elderly patients with schizophrenia or schizoaffective disorder.     

Efficacy and safety of aripiprazole and haloperidol versus placebo in patients with schizophrenia and schizoaffective disorder

BACKGROUND: Aripiprazole is an investigational agent for treating schizophrenia that has a novel pharmacologic profile. The present study investigated the efficacy, safety, and tolerability of aripiprazole and haloperidol compared with placebo. METHOD: A 4-week, double-blind, randomized study, conducted at 36 U.S. centers between July 1997 and June 1998, compared aripiprazole (15 mg/day, 30 mg/day) to placebo, with haloperidol (10 mg/day) as an active control. Fixed doses of each agent were administered from day 1 throughout the study. A total of 414 patients with a primary DSM-IV diagnosis of schizophrenia or schizoaffective disorder were randomized. Efficacy measures included the Positive and Negative Syndrome Scale (PANSS) total, PANSS positive, PANSS negative, PANSS-derived Brief Psychiatric Rating Scale (BPRS) core, Clinical Global Impressions (CGI)-Severity of Illness, and mean CGI-Improvement scores. Safety and tolerability evaluations included extrapyramidal symptoms (EPS), weight gain, serum prolactin level, and QTc interval. RESULTS: Both doses of aripiprazole and haloperidol, 10 mg, produced statistically significant (p < or = .05) improvements from baseline in PANSS total, PANSS positive, PANSS-derived BPRS core, and CGI-Severity scores and significantly lower CGI-Improvement scores at endpoint, compared with placebo. Aripiprazole, 15 mg, and haloperidol, 10 mg, significantly improved PANSS negative score compared with placebo. Both aripiprazole doses and haloperidol separated from placebo for PANSS total scores at week 2. Unlike haloperidol, aripiprazole was not associated with significant EPS or prolactin elevation at endpoint compared with placebo. There were no statistically significant differences in mean changes in body weight across the treatment groups versus placebo, and no patients receiving aripiprazole experienced clinically significant increases in QTc interval. CONCLUSION: Aripiprazole, effective against positive and negative symptoms, is a safe and well-tolerated potential treatment for schizophrenia and schizoaffective disorder.     

Clozapine augmented with risperidone in the treatment of schizophrenia: a randomized, double-blind, placebo-controlled trial

OBJECTIVE: The authors evaluated the efficacy and safety of augmenting clozapine with risperidone in patients with treatment-resistant schizophrenia. METHOD: In a randomized, double-blind, placebo-controlled 12-week trial, 40 patients unresponsive or partially responsive to clozapine monotherapy received a steady dose of clozapine combined with either placebo (N=20) or up to 6 mg/day of risperidone (N=20). Patient psychopathology was assessed at 2-week intervals with the Brief Psychiatric Rating Scale (BPRS) and the Scale for the Assessment of Negative Symptoms (SANS), among other measures. Movement disorders were assessed with the Simpson-Angus Rating Scale. RESULTS: From baseline to week 6 and week 12, mean BPRS total and positive symptom subscale scores were reduced significantly in both groups, but the reductions were significantly greater with clozapine/risperidone treatment. Reductions in SANS scores were also significantly greater with clozapine/risperidone treatment than with clozapine/placebo. The adverse event profile for clozapine/risperidone treatment was similar to that for clozapine/placebo. Simpson-Angus Rating Scale scores were lower with clozapine/risperidone treatment throughout the trial but increased to approach those of clozapine/placebo treatment at week 12. Clozapine/risperidone treatment did not induce additional weight gain, agranulocytosis, or seizures compared with clozapine/placebo treatment. CONCLUSIONS: In patients with a suboptimal response to clozapine, the addition of risperidone improved overall symptoms and positive and negative symptoms of schizophrenia. The combination appears to be safe and well tolerated. Augmentation of clozapine with risperidone may provide additional clinical benefit for patients who are nonresponsive or only partially responsive to clozapine alone.

Safety and efficacy of long-acting risperidone in schizophrenia: a 12-week, multicenter, open-label study in stable patients switched from typical and atypical oral antipsychotics

BACKGROUND: The safety and efficacy of the first long-acting injectable atypical antipsychotic, risperidone, were assessed in stable patients with schizophrenia switched from oral antipsychotic medications. METHOD: Data were collected between July 1, 2001, and October 25, 2002. The study population included patients from clinics, hospitals, and physicians' offices. After a 4-week run-in period, symptomatically stable patients with schizophrenia (DSM-IV) who had been taking haloperidol (N = 46), quetiapine (N = 45), or olanzapine (N = 50) received 25 mg of long-acting risperidone. The oral antipsychotics were continued for 3 weeks after the first injection of long-acting risperidone. Injections were administered every 2 weeks at 25 mg up to a maximum dose of 50 mg for 12 weeks in this multicenter, open-label study. RESULTS: Long-acting risperidone was well tolerated. Of the 141 patients who participated in the study, the most frequently reported adverse events were insomnia (16%), headache (15%), psychosis (11%), and agitation (11%). The mean increase in body weight was 0.4 kg. No other clinically relevant laboratory abnormalities or significant electrocardiogram changes were observed during the 12-week treatment. Extrapyramidal Symptom Rating Scale total scores were reduced during treatment with long-acting risperidone. Improvements in symptoms of schizophrenia were observed with long-acting risperidone at week 4 and continued through the 12-week treatment with significant reductions in total Positive and Negative Syndrome Scale (PANSS) scores at week 8 (-2.5, p <.01) and week 12 (-3.9, p <.001). At endpoint, 37% (50/135) of these stable patients were rated as clinically improved (> or = 20% decrease in PANSS total scores). CONCLUSIONS: Switching treatment from oral antipsychotics to long-acting risperidone without an intervening period of oral risperidone was safe and well tolerated. Long-acting risperidone also significantly reduced the severity of symptoms in these stable patients with schizophrenia.
