A Brexanolone Treatment Program at an Academic Medical Center: Patient Selection, 90-Day Posttreatment Outcomes, and Lessons Learned.

Background: Brexanolone is the first U.S. Food and Drug Administration-approved drug for the treatment of postpartum depression. Brexanolone is a positive allosteric modulator of the GABA receptor and is given over 60 hours by infusion in a medical setting. This drug has been shown to be effective at significantly reducing Hamilton Rating Scale for Depression scores at 60 hours and 30 days after infusion; however, data beyond 30 days have not yet been available. There have been limited clinical programs able to offer brexanolone owing to the complexity of setting up this treatment in a medical setting.

Purpose: This study sought to obtain follow-up data from 16 patients who received a brexanolone infusion at UNC Hospitals in Chapel Hill, NC, between October 2019 and December 2020 and were beyond the 30-day postinfusion time point. We describe the methods used to successfully implement this treatment program in an academic medical center and discuss associated challenges and lessons learned with patient selection and process improvements.

Methods: Hamilton Rating Scale for Depression scores were collected before and after infusion from 16 patients who received a brexanolone infusion at UNC. Patients were subsequently contacted for a follow-up interview to obtain Hamilton Rating Scale for Depression scores and complete a semistructured interview at least 30 days past treatment end (between 3 and 16 months after infusion).

Results: All 16 patients had a significant reduction in Hamilton Rating Scale for Depression scores at 60 hours, scores dropping on average from 23.9 (standard deviation = 2.6) to 7.6 (standard deviation = 2.9). Eleven of 16 patients consented to provide follow-up data. Follow-up Hamilton Rating Scale for Depression scores remained lower than postinfusion at an average of 6.7 points (standard deviation = 5.1).

Conclusion: With a strategic cross-disciplinary approach, a Clinical Brexanolone Treatment Program was established at UNC Hospitals in 2019. Sixteen patients have been treated in the program, and 11 participated in a follow-up interview. All 11 patients gave very positive feedback about their treatment. Our program has found brexanolone to be a useful clinical tool in treating women with significant symptoms of postpartum depression.
