Zuranolone: A Narrative Review of a New Oral Treatment for Postpartum Depression.

PURPOSE: Postpartum depression is a prevalent and overlooked mental disorder. Pathophysiology is thought to originate from a combination of biological and social factors, including hormones, and genetics. The consequences of untreated postpartum depression can be severe and negatively impact maternal and infant health. Zuranolone was approved as an oral agent in August 2023 for the treatment of postpartum depression in adults. The purpose of this article is evaluating the clinical aspects of zuranolone, including safety and efficacy pertaining to the drug and the clinical data that led to its approval. METHODS: A literature search was conducted using PubMed, Web of Science, and EMBASE with the terms postpartum depression, postpartum depression management, and zuranolone to locate relevant data for this narrative review. The prescribing information of zuranolone and clinicaltrials.gov were also utilized. FINDINGS: Two Phase III trials (Study 1-NCT04442503 and Study 2-NCT02978326) led to the approval of zuranolone by the Food and Drug Administration (FDA) based on clinically meaningful improvement in depressive symptoms. The trials met their primary endpoint, a change from baseline in HAM-D total score at day 15 (Study 1; 95% CI -6.3 to -1.7, P = 0.001: Study 2; 95% CI (-6.9 to -1.5, P = 0.003). IMPLICATIONS: Zuranolone, an oral and rapidly acting antidepressant, represents a promising new oral treatment option for individuals with postpartum depression.

Rozanolixizumab: A New Therapy in the Treatment of Myasthenia Gravis.

OBJECTIVE: The aims of this article are to review the clinical aspects of rozanolixizumab, to describe clinical trial results that led to the drug's approval, and to examine the impact on patient care to aid clinical decision making. DATA SOURCES: A PubMed search was conducted using the terms Rystiggo™, rozanolixizumab, rozanolixizumab therapy, and myasthenia gravis. The most recent prescribing information was also used for information relating to the drug and for identification of pertinent studies. STUDY SELECTION/DATA EXTRACTION: Phase I, II, and III randomized controlled trials were all eligible for inclusion. Meeting abstracts and articles focusing on the use of rozanolixizumab or any indication other than generalized myasthenia gravis were excluded from this article. DATA SYNTHESIS: Food and Drug Administration approval of rozanolixizumab is based on the phase III MycarinG study in patients with generalized myasthenia gravis. A phase II trial explored initial clinical efficacy and safety pertaining to the dose and frequency of rozanolixizumab across 2 treatment periods in patients with moderate to severe myasthenia gravis. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING AGENTS: Rozanolixizumab is the first therapy approved to treat patients positive for both types of antibodies, anti-acetylcholine receptor or anti-muscle-specific tyrosine kinase, in generalized myasthenia gravis. CONCLUSION/RELEVANCE: The approval of rozanolixizumab represents an advancement in therapy for generalized myasthenia gravis. The provision of individualized, targeted, and well-tolerated treatment is valuable for the patients whose myasthenia gravis is not well controlled and who are seeking a medication with a rapid onset of action to improve their symptoms and overall quality of life.
