Lipocine Announces Last Patient Last Visit in Pivotal Phase 3 Trial of LPCN 1154 for Postpartum Depression (PPD)

SALT LAKE CITY, Feb. 18, 2026 /PRNewswire/ -- Lipocine Inc. (NASDAQ: LPCN), a biopharmaceutical company leveraging its proprietary technology platform to develop innovative products with effective oral delivery, today announced that the last patient has completed the final study visit (Last Patient Last Visit) in its Phase 3 clinical trial evaluating LPCN 1154 (oral brexanolone) for the treatment of postpartum depression (PPD).

The randomized, double-blind, placebo-controlled study enrolled a total of 90 patients with severe PPD, having an average baseline Hamilton depression rating scale (HAM-D) of 28.3. LPCN 1154 has shown a positive safety profile, with all reported nervous system adverse events being mild to moderate in severity. Furthermore, there were no instances of drug discontinuation, excessive sedation, loss of consciousness, or drug-related serious adverse events.

"We are encouraged by the high study drug compliance and safety profile observed in this study. which we believe to be attributable to the short, 48-hour treatment duration, coupled with the regimen's ease of use and tolerability," said Mahesh Patel, CEO of Lipocine. "Provided the efficacy results are positive, the established safety profile could promote greater willingness among healthcare professionals to prescribe LPCN 1154 as a patient-centric treatment option for women suffering from postpartum depression."

Postpartum depression is a serious condition affecting a significant number of new mothers and can be life-threatening if left untreated. Existing treatment options are often limited by access to care, burdensome administration, or tolerability challenges, and may take weeks to months to provide relief. LPCN 1154 is designed to address these limitations with a differentiated profile that may deliver faster symptom relief, a shorter course of treatment, and better tolerability in a convenient oral medication taken at home.

The Phase 3 trial design is informed by a strong foundation of clinical and translational evidence. Brexanolone has demonstrated established antidepressant efficacy in multiple intravenous infusion studies, including the pivotal Phase 3 program that supported approval of Zulresso™ for PPD. LPCN 1154 achieved bio-equivalent systemic exposure to the intravenous Brexanolone. In addition, the current study aligns closely with the Zulresso registrational trials with respect to patient population (women with severe PPD and similar baseline HAM-D scores), treatment duration, sample size, and the primary efficacy endpoint (change from baseline in HAM-D score at Hour 60).

About the Phase 3 Study

The pivotal, randomized, double-blind study is evaluating LPCN 1154 compared to placebo in women aged 15 years and older diagnosed with severe PPD. Following feedback from the U.S. Food and Drug Administration (FDA), this single confirmatory trial was conducted in an outpatient setting and administration of LPCN 1154 does not require medical monitoring by a healthcare provider. Nineteen clinical sites across the United States participated. Data from this Phase 3 trial are expected to support a 505(b)(2) NDA submission for LPCN 1154 in 2026. For more information about the phase 3 study, refer to clinicaltrials.gov: NCT06979544.

About LPCN 1154

LPCN 1154 is an oral formulation of brexanolone being developed to provide rapid relief of postpartum depression in a convenient, at-home treatment. It has potential as first line treatment choice for women with PPD. It also has characteristics that  could be particularly beneficial to patients with severe PPD (including those with elevated suicide risk) for whom rapid improvement is a priority. LPCN 1154 is expected to offer a compelling safety profile for breastfeeding mothers. Data from a qEEG study in healthy volunteers demonstrated target engagement consistent with robust central nervous system (CNS) activity, with concentration- and time-dependent post-dose changes in qEEG.

About Postpartum Depression and Unmet Needs

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. Hormonal changes leading to GABA dysfunction are common in depression and pregnancy. 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. Further, obstetricians are comfortable making a diagnosis and prescribing antidepressants for PPD. Traditional antidepressants, not approved for PPD, have slow onset of action, side effects such as weight gain, and do not demonstrate adequate remission.
