Weight change during long-term treatment with lurasidone: pooled analysis of studies in patients with schizophrenia.

ABSTRACT: The objective of this analysis was to evaluate the effect of 12 months of treatment with lurasidone on weight in patients with schizophrenia. Post-hoc, observed-case analysis included pooled data from six studies on 40-160 mg/day lurasidone; two studies included active comparators (2-6 mg/day risperidone or 200-800 mg/day quetiapine XR). Overall, 593 patients completed 12 months of treatment (N=471 lurasidone, N = 89 risperidone, N = 33 quetiapine XR). The mean baseline weight was 72.8, 80.8, and 72.4 kg in the lurasidone, risperidone, and quetiapine XR groups, respectively. The mean weight change at month 12 was -0.4 kg with lurasidone, +2.6 kg with risperidone, and +1.2 kg with quetiapine XR. Weight gain of at least 7% from study baseline was observed in 16.0, 25.8, and 15.2% of patients, and weight loss of at least 7% was seen in 18.5, 6.7, and 9.1% of patients treated with lurasidone, risperidone, and quetiapine XR, respectively. A shift from normal/underweight baseline BMI status to overweight/obese at month 12 occurred in 10.2, 27.6, and 15.0% of patients in the lurasidone, risperidone, and quetiapine XR groups, respectively. Conversely, 14.3, 1.7, and 7.7% of patients, respectively, shifted from overweight/obese to normal/underweight. In summary, a low potential for clinically significant weight gain was observed in patients with schizophrenia treated continuously with lurasidone for 12 months.

Project description:The pooled analysis of two double-blind, randomized, multicenter, phase-3 studies evaluated predictors of improvement or worsening of schizophrenia-related caregiver burden following paliperidone palmitate long-acting injectables (1-monthly [PP1M] and 3-monthly [PP3M]) treatment. Caregivers were offered to complete the involvement evaluation questionnaire (involvement evaluation questionnaire; 31-item scale). Total, 1498 caregivers (intent-to-treat open-label analysis set, n?=?1497; mean [SD] age: 51.5 [13.02] years, 27 countries) were included: 49% were parents and >50% caregivers spent >32?hours/week in caregiving. Majority of caregivers with considerable burden (n?=?1405; mean [SD] baseline involvement evaluation questionnaire scores: 28.4 [15.07]) improved significantly from baseline to end-of-study (n?=?756; mean [SD] change from open-label baseline to double-blind endpoint in long-acting injectable scores:-8.9 [14.73]); most improvements were seen in urging followed by worrying, tension, and supervision domains (mean [SD] change from open-label baseline to double-blind endpoint in involvement evaluation questionnaire scores, urging: -3.7 [6.45]; worrying:-2.6 [5.11]; tension:-2.3 [4.84]; supervision: -1.3 [3.69]). Improvements significantly correlated with relapse status, patient age, and age of diagnosis (p?<?0.001) while long-acting injectable use at baseline, number, and duration of prior psychiatric hospitalizations (<24 months) had no significant correlation. Caregiver burden was significantly improved for patients on prior oral antipsychotics post-switching to long-acting injectable, with less impact on leisure days and hours spent in caregiving (p?<?0.001). Family members of patients with schizophrenia experience considerable caregiver burden. Switching from oral antipsychotic to long-acting injectable can provide meaningful and significant improvement in caregiver burden.Drug formulationEASING THE TOLL OF CAREGIVING: Switching from oral to long-acting injectable antipsychotic medication improves overall caregiver burden. The physical, emotional and financial toll of providing care for patients with schizophrenia is often underestimated. Poor adherence to conventional oral antipsychotics is a major cause of symptomatic relapse in patients and of stress for carers. Srihari Gopal and colleagues at Janssen Pharmaceuticals have pooled data from two large studies involving 1498 caregivers across 27 countries. They found that administration of either 1- or 3-monthly long-acting injectable antipsychotics not only eased the burden of daily dosing and patient compliance, but also had a positive impact on the stress conditions of caregivers. Using the Involvement Evaluation Questionnaire to measure caregiver burden, the authors showed that the switch in drug formulation decreased the need to urge patients to self-care and the hours spent caregiving.
