Lipocine Provides Progress Update on LPCN 1154 Phase 3 Clinical Trial in Postpartum Depression (PPD)

One-Third of Patients Randomized; Topline Results Expected in 2Q 2026 DSMB Safety Review Update Planned for 4Q 2025 , /PRNewswire/ -- Lipocine Inc. (NASDAQ: LPCN), a biopharmaceutical company leveraging its proprietary technology platform to develop innovative products with effective oral delivery, today provided an update on its ongoing pivotal Phase 3 clinical trial evaluating LPCN 1154 (oral brexanolone) for the treatment of postpartum depression (PPD). The study is progressing on track with one-third of planned patients randomized. Topline results are anticipated in the second quarter of 2026. A meeting of the independent Data Safety Monitoring Board (DSMB) to review safety data from the study in the one-third patients randomized will be held, and the Company plans to provide a safety update in the fourth quarter of 2025 post DSMB review. "We are very encouraged by the steady enrollment momentum in our pivotal Phase 3 trial and are pleased to see the program advance as planned," said Mahesh Patel, CEO of Lipocine. "LPCN 1154 is designed to be differentiated from existing options for PPD, with its 48-hour dosing schedule, and potential for rapid, meaningful clinical benefit. We believe it has the potential to become the standard of care for women suffering from this condition. We intend to use the data from this Phase 3 trial to support a 505(b)(2) NDA submission in 2026." 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 constructive feedback from the U.S. Food and Drug Administration (FDA), the trial is being conducted entirely in an outpatient setting and does not require medical monitoring by a healthcare provider.

LPCN 1154 is expected to have characteristics that could be particularly appealing to patients with PPD, acutely elevated suicide risk, and in whom rapid improvement is a priority while presenting no significant risk of adverse reactions to breastfed infants from exposure to brexanolone. 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. Results from a recent survey (Truist Securities Research, January 2024) show that obstetricians believe approximately 20-40% of their patients may suffer from PPD. 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 post-acute treatment.
