Sage Therapeutics announced positive top-line results from two phase III clinical trials with its proprietary i.v. formulation of brexanolone (USAN; formerly SAGE-547) in postpartum depression (PPD). The Hummingbird program included two phase III multicenter, randomized, double-blind, parallel-group, placebo-controlled trials (Study 202B and Study 202C). Trial participants in 202B were required to have a Hamilton Rating Scale for Depression (HAM-D) score of 26 or above prior to treatment. These patients were randomized to one of three treatment groups (brexanolone 90μg/kg/hour, brexanolone 60μg/kg/hour, or placebo) on a 1:1:1 basis. Trial participants in 202C were required to have a HAM-D score of between 20 and 25 prior to treatment. These patients were randomized to one of two treatment groups (brexanolone 90μg/kg/hour or placebo) on a 1:1 basis. Brexanolone achieved the primary endpoint in both trials, a mean reduction from baseline in the HAM-D total score compared to placebo at 60 hours (Study 202B: p=0.0242 for 90µg/kg/h dose and p=0.0011 for 60µg/kg/h dose; Study 202C: p=0.0160 for 90µg/kg/h dose). Patients treated with brexanolone demonstrated mean reductions from baseline in HAM-D total scores of 14 to 20 points at 60 hours maintained to 30 days in both trials. Brexanolone was generally well-tolerated and showed a similar safety profile as seen in earlier studies.

Sunovion Pharmaceuticals issued results of a phase III clinical study evaluating Latuda (lurasidone HCI) in children and adolescents (10 to 17 years of age) with major depressive episodes associated with bipolar I disorder (bipolar depression). In the six-week, randomized, double-blind, placebo-controlled study, 347 children and adolescents 10 to 17 years of age received LATUDA flexibly dosed (20 to 80mg/day) or placebo. LATUDA was associated with statistically significant and clinically meaningful improvement in bipolar depression symptoms compared to placebo, based on the primary efficacy endpoint of change from baseline to week six on the Children’s Depression Rating Scale, Revised (CDRS-R) total score (-21.0 vs. -15.3; effect size = 0.45, p<0.0001). Statistically significant and clinically relevant change from baseline to week six on the Clinical Global Impression-Bipolar Version, Severity of Illness (CGI-BP-S) score (depression) was also seen with LATUDA compared to placebo (-1.49 vs. -1.05; effect size = 0.44, p<0.0001). LATUDA was generally well-tolerated. The most common treatment-emergent adverse events (TEAEs) reported for LATUDA compared to placebo were nausea (16% vs. 5.8%), somnolence (9.1% vs. 4.7%), weight gain (6.9% vs. 1.7%), vomiting (6.3% vs. 3.5%), dizziness (5.7% vs. 4.7%) and insomnia (5.1% vs. 2.3%). LATUDA is currently indicated in the U.S. for the treatment of adults with bipolar depression as monotherapy and as adjunctive therapy with lithium or valproate and for the treatment of schizophrenia in adults and adolescents (13 to 17 years of age). These data have been submitted to the FDA to support an sNDA.

Neuralstem released results of a phase Ib study of NSI-189 for major depressive disorder (MDD). In this single-site study, 24 patients with confirmed diagnosis of recurrent MDD were treated orally with NSI-189 in three equal dose cohorts (8/dose cohort; 40mg QD, 40mg BID and 40mg TID) for 28 days. Each dose cohort consisted of randomized, double-blinded, placebo controls at 1:3 ratio of placebo:drug. All subjects stayed in-clinic for the 28-day treatment period. After this period, the subjects returned to the clinic for follow-up measures for up to an additional eight weeks post-dosing. A significant number of patients on active treatment demonstrated clinical improvement by a reduction in total Montgomery-Asberg Depression Rating Scale (MADRS) scores >/= 15.9 points, which continued eight weeks after dosing stopped. The company plans to launch a large, multi-site, phase II study in the second quarter of 2015.
