First Subject Dosed in the Clinical Bridge Study with Lipocine Depression Candidate, LPCN 1154
  • LPCN 1154 is an oral formulation of brexanolone in development for the rapid relief of postpartum depression (PPD)
  • Topline study results expected in H1 2023

SALT LAKE CITY, April 3, 2023 /PRNewswire/ -- Lipocine Inc. (NASDAQ: LPCN), a biopharmaceutical company focused on treating Central Nervous System (CNS) disorders by leveraging its proprietary platform to develop differentiated products, today announced that the first participant has been dosed in a pilot clinical bridge study of LPCN 1154 (oral brexanolone) and approved injectable brexanolone.   The U.S. Food and Drug Administration (FDA) has agreed with Lipocine's proposal for establishing the efficacy and safety of LPCN 1154 in women with PPD through a clinical (pharmacokinetic) bridge to an approved IV infusion of brexanolone via a 505(b)(2) NDA filing.  Lipocine plans to conduct a pivotal study designed to support NDA filing pending results from the pilot clinical bridge study. 

LPCN 1154 is targeted to be a rapid onset  "at home" oral treatment option for PPD with improved treatment access and ease of use without disrupting bonding/breast feeding interactions compared to the current, approved PPD standard of care with its significant limitations.

The pilot clinical bridge study is an open label, randomized, partial crossover study. The primary objective of the study is to compare the exposures of multidose regimens of orally administered LPCN 1154 and a continuous IV infusion of brexanolone in healthy postmenopausal women and to inform the dose selection for the pivotal study. The secondary objective is to evaluate the safety and tolerability of multidose regimens of oral LPCN 1154. The study is expected to enroll a total of 12 participants and is being conducted at a single center in the US. Results are expected in the first half of 2023.

"We are excited about our development progress for LPCN 1154," said Dr. Mahesh Patel, President and CEO of Lipocine Inc.  "The days and weeks after childbirth are critical time periods for the care of both mother and newborn, with urgent relief a high priority for patients with depression," continued Dr. Patel. "We believe that, if approved, LPCN 1154, comprising a bioidentical active, has the potential to be a differentiated treatment for PPD, providing a convenient oral treatment option for administration in outpatient settings that would be less burdensome on patients, caregivers, and providers."

About Postpartum Depression

PPD is a major depressive disorder with onset either during pregnancy or within four weeks of delivery, with symptoms persisting up to 12 months after childbirth. Symptoms of PPD include hallmarks of major depression, including, but not limited to, sadness, depressed mood, loss of interest, change in appetite, insomnia, sleeping too much, fatigue, difficulty thinking/concentrating, excessive crying, fear of harming the baby/oneself, and/or thoughts of death or suicide. Approximately 500,000 women are affected by PPD annually in the United States, and according to the CDC, an estimated 175,000 women suffer from moderate to severe PPD, and 10-15% of PPD patients have severe depression.  The current approved standard of care is continuous infusion of intravenous brexanolone which requires inpatient administration with frequent monitoring.
