Trial or other data
Nov 17: SAGE Therapeutics announces the success of two PIII trials of brexanolone in severe postpartum depression and moderate postpartum depression. Brexanolone hit the primary endpoint in both trials (reduction in the Hamilton Rating Scale for Depression [HAM-D] compared to placebo at 60 hours). Patients on brexanolone had a decrease from baseline in HAM-D scores of 14 to 20 points at 60 hours, and maintained them to 30 days in both trials .
Aug 17: results from PII trial published in full in the Lancet; generic name updated .
Jul 16: PIII trial program for this indication started, with two parallel trials investigating use in severe (NCT02942004, estimated n=120) and moderate (NCT02942017, estimated n=100) postpartum depression; each study will randomise patients to brexanolone or placebo with a primary outcome of change from baseline in Hamilton Rating Scale for Depression (HAMD) total score. Estimated primary completion date for both studies is December 2017 .
Jul 16: initial topline results from a small PII trial (NCT02614547) have been announced; in this randomised controlled double-blind study, women with severe post-natal depression received IV SAGE-547 or placebo: primary outcome was HAM-D score at 60 hours. Of 32 women enrolled, results were presented for 21 - in this group, there was a statistically significant reduction in HAM-D score vs. placebo, with a mean difference of 12 points [5,6].
