An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. A TEAE is defined as an AE with onset on or after the start of study drug infusion, or any worsening of a pre-existing medical condition/AE with onset on or after the start of study drug infusion.
Third-line agents were anesthetic agents that were administered in order to reach a seizure or burst suppression electroencephalogram (EEG) pattern. For this study, third-line agents were defined as continuous intravenous infusions of pentobarbital/thiopental, midazolam, propofol, and ketamine at maintenance doses alone or in combination sufficient to produce a burst or seizure suppression pattern on the EEG. A responder was a participant who was able to be weaned off all third-line agents prior to the end of the SAGE-547 or placebo infusion and remain off all third-line agents for \>=24 hours after the end of the study drug infusion. The primary analysis was a comparison between SAGE-547 and placebo of the proportion of responders.

An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of a medicinal (investigational) product whether or not related to the medicinal (investigational) product. A TEAE is defined as an AE with onset after the start of brexanolone, or any worsening of a pre-existing medical condition/adverse event with onset after the start of brexanolone and throughout the study.
The HAM-D total score comprises a sum of the 17 individual item scores. Items scored in a range of 0 to 2 include: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. The following items are scored in a range of 0 to 4: agitation, depressed mood, feelings of guilt, suicide, work and activities, retardation, anxiety (psychic and somatic), and hypochondriasis. The total score can range from 0 to 52, and higher scores indicate a greater degree of depression. A negative change from baseline indicates less depression. A positive change from baseline indicates more depression.
AEs were any untoward medical occurrences in a participant who received study treatment without regard to possibility of causal relationship.

TESAEs were defined as AEs with onset after the start of SAGE-547 infusion, or any worsening of a pre-existing medical condition or AEs with onset after the start of SAGE-547 infusion and until 30 days after the end of infusion (Day 34).

Brexanolone is being studied for several psychiatric and neurological conditions, including posttraumatic stress disorder, postpartum depression, postpartum psychosis, and tinnitus. It is a small molecule developed by Supernus Pharmaceuticals, Inc. (ticker: SUPN). The program is in Phase 1 development, and clinical trials have evaluated it in adults and adolescent females.
Brexanolone targets GABA-A receptor subunits, specifically GABRA1, GABRB2, GABRG2, GABRB3, GABRA4, and GABRG3. It acts as a positive allosteric modulator of these receptors. This mechanism enhances inhibitory neurotransmission in the central nervous system, which is the basis for its investigation in psychiatric and neurological conditions.
Brexanolone is being developed by Supernus Pharmaceuticals, Inc., which trades under the ticker SUPN. The company is responsible for the clinical development program across the studied indications, including PTSD, postpartum depression, postpartum psychosis, and tinnitus.
Brexanolone is in Phase 1 clinical development according to the overall program status. Individual trials have been conducted across different phases, including Phase 1, Phase 2, Phase 3, and Early Phase 1 studies. It is an investigational agent and has not been approved by the FDA for the indications described here.
Brexanolone has been evaluated in several clinical trials. These include NCT05645432 in adults with tinnitus, NCT05314153 in postpartum psychosis, NCT05223829 in PTSD with alcohol use disorder, and NCT03665038 in adolescent females with postpartum depression. The trials have been conducted in the United States.
