Abstract
Objective: To evaluate the safety and effectiveness of 6 months of treatment with lurasidone in older adults with a diagnosis of bipolar I depression. Design: Post-hoc analysis of a multicenter, 6-month, open-label extension study. Setting: Outpatient. Participants: Patients aged 55 to 75 years with a DSM-IV-TR diagnosis of bipolar I depression who had completed 6 weeks of double-blind, placebo-controlled treatment with either lurasidone monotherapy (1 study) or adjunctive therapy with lithium or valproate (2 studies). Intervention: Flexible doses of lurasidone, 20 to 120 mg/day, either as monotherapy, or adjunctive with lithium or valproate. Measurements: Effectiveness was assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS; change from open-label-baseline to month-6, observed case analysis). Results: A total of 141 older adults entered the extension study (monotherapy, N = 55; 39%; adjunctive therapy, N = 86; 61%). At the end of 6 months of open-label treatment with lurasidone, as monotherapy or adjunctive therapy, minimal changes were observed in the older adult sample in mean weight (−1.0 kg and −0.4 kg, respectively); and median total cholesterol (−2.0 mg/dL and +6.0 md/dL, respectively), triglycerides (+2.5 mg/dL and +6.0 mg/dL, respectively), and HbA1c (0.0% and −0.1%, respectively). Patients treated with 6 months of lurasidone showed a mean improvement on the MADRS in both the monotherapy (−6.2) and adjunctive therapy (−6.7) groups. Conclusions: Results of these post-hoc analyses found that up to 7.5 months of lurasidone treatment for bipolar depression in older adults was associated with minimal effects on weight and metabolic parameters, with low rates of switching to hypomania or mania, and was well tolerated. The antidepressant effectiveness of lurasidone in this age group was maintained over the 6-month treatment period.
