Testosterone Undecanoate

Per the Drug Safety Monitoring Board (DSMB) meeting evaluating one-third of planned participants, study to continue as planned More than half of planned participants have completed dosing with no dose reductions, discontinuations, drug-related SAEs, loss of consciousness, or excessive sedation reported Topline results are on track for the second quarter of 2026 SALT LAKE CITY, Nov. 18, 2025 /PRNewswire/ -- Lipocine Inc. (NASDAQ: LPCN), a biopharmaceutical company leveraging its proprietary technology platform to develop innovative products with effective oral delivery, today announced the completion of a scheduled independent Data Safety Monitoring Board review of its ongoing Phase 3 clinical trial evaluating LPCN 1154 (oral brexanolone) for the rapid relief treatment of PPD. This was the first of two DSMB reviews planned during the study and conducted after approximately one-third of planned 80 participants completed at least the day seven follow-up visit (n=30). The DSMB recommended that the trial continue as planned without modification. 47 participants have completed dosing to date and there have been no treatment discontinuations or dose reductions required, and no reports of drug-related serious adverse events. No cases of excessive sedation or loss of consciousness have been reported to date in the development of LPCN 1154. "We are encouraged by the safety profile observed in our clinical experience to date with our oral product candidate comprising GABAA positive allosteric modulating neuroactive steroid with low sedation," said Mahesh Patel, CEO of Lipocine. "Target attributes of LPCN 1154, including superior tolerability, rapid relief, and a 48-hour treatment duration, could be a game changer in the treatment of PPD, a debilitating and life-threatening condition. We look forward to LPCN 1154 Phase 3 study results, expected in the second quarter of 2026." 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 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. Nineteen clinical sites across the United States are participating. The readout from the second interim DSMB meeting and the safety update is targeted for early in the first quarter of 2026. Data from this Phase 3 trial are expected to support a 505(b)(2) NDA submission for LPCN 1154 in 2026. For more information, refer to clinicaltrials.gov: NCT06979544. About LPCN 1154 LPCN 1154 is an oral formulation of brexanolone in development targeted for administration resulting in rapid relief of PPD. While it is expected that LPCN 1154 could be the first line treatment choice for women with PPD, it may 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.

RALEIGH, N.C., Nov. 12, 2025 (GLOBE NEWSWIRE) -- Marius Pharmaceuticals, Inc. a patient-centric healthcare company committed to advancing innovative therapies for testosterone deficiency, today announced that Health Canada has approved KYZATREX® (testosterone undecanoate) CIII capsules. KYZATREX is a prescription drug used to treat adult men who have low or no testosterone levels due to certain medical conditions. This approval marks a significant milestone as Marius expands its reach beyond the U.S. market and makes the only oral testosterone replacement therapy option available under a softgel capsule dosage form in Canada. Building on Marius’s earlier submission to Health Canada in July 2024, the company is now poised to provide Canadian men and their healthcare providers with an additional treatment option. “Today’s approval of KYZATREX by Health Canada is a major milestone for Marius Pharma and for men’s health in Canada,” said Amit Shah, Chief Operating Officer of Marius Pharmaceuticals. “We recognize the burden that testosterone deficiency places on men’s physical, cognitive, and metabolic health, and we are committed to expanding access to effective, convenient treatment options. We look forward to partnering with Canadian healthcare providers to bring KYZATREX to patients who may benefit.” Testosterone deficiency (TD), also referred to as hypogonadism, can result from a variety of underlying medical conditions and is associated with symptoms such as low libido, fatigue, muscle weakness, mood disturbances, and metabolic dysfunction. In Canada, the crude prevalence of biochemical testosterone deficiency is estimated to be approximately 25% among men aged 40–62 years, or approximately 3 million men.1,2 This underscores a substantial patient population that may benefit from increased awareness, diagnosis, and access to effective therapies. With Health Canada approval in hand, Marius will launch KYZATREX in the Canadian market soon, working collaboratively with Canadian providers to ensure appropriate patient access, education, and monitoring. KYZATREX will be available through multiple telehealth and traditional provider options in the first half of 2026.The availability of an oral testosterone option presents a convenient alternative to injectable or transdermal formulations. About Marius Pharmaceuticals Marius Pharmaceuticals strives to better the lives of patients by focusing on therapies designed for hypogonadism or Testosterone Deficiency. The company's vision is to holistically improve metabolic health and mitigate significant unnecessary costs to the global healthcare system. For more information, please visit www.mariuspharma.com. About KYZATREX® (testosterone undecanoate)KYZATREX is a proprietary softgel oral formulation absorbed primarily via the lymphatic system (meaning it is not toxic to the liver) and indicated in adult males for conditions associated with a deficiency or absence of endogenous testosterone. The safety and efficacy of KYZATREX was demonstrated in a phase 3, multi-center, open-label, six-month study in 155 hypogonadal males between 18 and 65 years of age with documented hypogonadism, as defined by a below normal serum testosterone level (≤281 ng/dL) and at least one sign or symptom of testosterone deficiency. In the efficacy population (n=139), 88 percent of hypogonadal men treated with KYZATREX achieved a mean plasma total testosterone concentration (Cavg) over 24 hours within the normal range (222-800 ng/dL) on the final pharmacokinetic (PK) visit of the study at Day 90 (primary endpoint). Based on exploratory endpoints, patients who received KYZATREX reported improvements in symptoms of low testosterone, including quality of life, energy/fatigue, erectile function, sexual intercourse, and mood. The most common side effect reported in ≥2 percent of KYZATREX patients was increased blood pressure (2.6%). The safety and efficacy of KYZATREX in males less than 18 years old have not been established. Please see additional Important Safety Information for KYZATREX below or visit www.kyzatrex.com.
