SALT LAKE CITY, May 16, 2023 — Lipocine Inc. (NASDAQ: LPCN), today announced positive topline results from a pilot clinical PK bridge study of LPCN 1154 (oral brexanolone) with a comparator, IV brexanolone. The pilot study is an important step in Lipocine’s ongoing program to develop LPCN 1154 for PPD. Lipocine is a biopharmaceutical company focused on treating Central Nervous System (CNS) disorders by leveraging its proprietary platform to develop differentiated products.
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. LPCN 1154 is targeted to be a differentiated oral option with rapid-onset, robust efficacy, and short treatment duration as a mono or add-on therapy for patients with unresolved depression symptoms.
StudyDesign and Results
The pilot PK bridge study was an open label, randomized, partial crossover study in healthy postmenopausal women. The primary objective of the study was to compare the PK (AUC∞ and Cmax) of two LPCN 1154 oral multi-dose regimens (DR 1: dosing regimen 1 for 3.5 days, DR 2: dosing regimen 2 for 2.5 days) and a continuous IV infusion dosing regimen of brexanolone (per label for 2.5 days, up to 90 µg/kg/hr), to inform the dose selection for the planned confirmatory pivotal PK registration study. The secondary objective was to evaluate the safety and tolerability of multidose regimens of LPCN 1154. The study enrolled a total of twelve participants and was conducted at a single phase 1 unit in the US.
Ratios (%) of geometric mean - LPCN 1154 regimens vs IV brexanolone regimens:
| PK Parameter | DR 1 vs <br>IV 60 µg* | DR 1 vs <br>IV 90 µg | DR 2 vs <br>IV 60 µg* | DR 2 vs <br>IV 90 µg | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| AUC∞ | 98 | % | 77 | % | 106 | % | 83 | % | ||||
| Cmax | 114 | % | 68 | % | 134 | % | 79 | % |
60 µg and 90 µg refer to the maximum dose in the IV regimen (60 µg/kg/hr and 90 µg/kg/hr). *Interpolated from 90 µg/kg/hr IV infusion data
| ● | DR<br> 1 regimen resulted in comparable brexanolone exposure (Cmax and AUC∞)<br> to IV brexanolone 60 µg/kg/hr regimen |
|---|---|
| ● | DR<br> 2 regimen resulted in exposure levels (Cmax and AUC∞) within<br> the two clinically-effective IV brexanolone dosing regimens (60 µg/kg/hr and 90 µg/kg/hr) |
| ● | Dosing<br> regimen identified for confirmatory PK study |
Consistent with prior experience, LPCN 1154 appeared safe and well-tolerated in this study. All AEs were mild or moderate in severity, and similar across trial arms. No hypoxia, sedation-related, or serious adverse events were observed.
The U.S. Food and Drug Administration (FDA) has agreed with Lipocine’s proposal for establishing the efficacy of LPCN 1154 in women with PPD through a clinical PK bridge to the approved IV infusion of brexanolone via anticipated 505(b)(2) NDA filing and streamlined approval pathway. Lipocine plans to initiate a single confirmatory pivotal PK study in the second half of 2023 to establish efficacy, pending FDA feedback.
“The encouraging positive results from this pilot PK bridge study support our development plan for LPCN 1154,” said Dr. Mahesh Patel, President and CEO of Lipocine. “The days and weeks after childbirth are critical time periods for the care of both mother and newborn. PPD is a serious condition in need of a highly effective, oral, fast-acting and short treatment duration option. We believe rapid relief matters and, if approved, LPCN 1154 has the potential to be a differentiated preferred treatment for PPD.”

AboutLPCN 1154
LPCN 1154 is an oral formulation of brexanolone in development targeted for rapid relief of postpartum depression (PPD). Brexanolone is a bioidentical to naturally occurring neuroactive steroid, allopregnanolone, a positive allosteric modulator of y-aminobutyric acid (GABA) receptor. LPCN 1154 is expected to have characteristics that could be particularly appealing to patients with severe 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.
AboutPostpartum 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. Approximately 500,000 women are affected by PPD annually in the United States. Traditional antidepressants, not approved for PPD, have slow onset of action, side effects such as sexual dysfunction and weight gain, and do not demonstrate adequate remission post-acute treatment. The current approved standard of care is continuous infusion of intravenous brexanolone which requires inpatient administration with significant limitations.
