Premenstrual Dysphoric Disorder

Women affected by premenstrual disorders have a higher risk of perinatal depression compared with those who do not, according to new research. The relationship works both ways: those with perinatal depression are also more likely to develop premenstrual disorders after pregnancy and childbirth. This study suggests that a common mechanism might contribute to the two conditions. Women affected by premenstrual disorders have a higher risk of perinatal depression compared with those who do not, according to research published March 28 in the open access journal PLOS Medicine. The relationship works both ways: those with perinatal depression are also more likely to develop premenstrual disorders after pregnancy and childbirth. This study suggests that a common mechanism might contribute to the two conditions. Menstruating women experience cyclical hormone fluctuations through puberty, menstrual cycle, pregnancy and menopause. Some women have difficult to manage symptoms of low mood and depression during these fluctuations. Between a fifth and a third of women are reportedly affected by premenstrual disorders and 11% of mothers suffer perinatal depression -- depressive symptoms during pregnancy and up to 12 months after delivery. Qian Yang and colleagues at the Karolinska Institutet, Sweden and University of Iceland used the Swedish nationwide registers from 2001 to 2018 and identified 84,949 women with perinatal depression and 849,482 unaffected women. The researchers matched the women on age and calendar year, and further controlled for demographic factors, smoking, BMI, parity and history of psychiatric disorders. Among women with perinatal depression, almost 3% had premenstrual disorders before pregnancy compared with 0.6% of matched unaffected women. Women with perinatal depression were also twice as likely to report premenstrual disorders when the menstruation resumed after childbirth, compared to those unaffected by perinatal depression. The research sheds light on the association between the two conditions and supports a theory that they may share underlying biological mechanisms and/or risk factors. Understanding this association could help healthcare providers to better target support to women most likely to be affected. The authors add, "This study reveals a strong bidirectional relationship between perinatal depression and premenstrual disorders, using data from over 900,000 pregnancies. The findings suggest that both disorders may exist on a continuum, and emphasize the importance of recognizing these susceptibilities in clinical practice."

Fasedienol PALISADE Phase 3 program for the acute treatment of social anxiety disorder remains on track PALISADE-3 trial initiation anticipated in 1H 2024; PALISADE-4 trial initiation anticipated in 2H 2024 SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Vistagen (Nasdaq: VTGN), a late clinical-stage biopharmaceutical company pioneering neuroscience to deliver first-in-class therapies for psychiatric and neurological disorders, today reported financial results for its fiscal year 2024 third quarter ended December 31, 2023 and provided a corporate update. "Momentum from clinical and corporate milestones achieved through the end of last quarter have significantly advanced our efforts to develop and commercialize fasedienol as a potential first-in-class acute treatment for adults with social anxiety disorder. Building on the positive results of our PALISADE-2 Phase 3 trial in SAD, we remain on track to initiate our PALISADE-3 Phase 3 trial in SAD during the first half of this year," said Shawn Singh, Chief Executive Officer of Vistagen. "In parallel, we continue to make significant progress toward Phase 2B development of two additional clinical-stage neuroscience assets in our pipeline, itruvone for major depressive disorder and hormone-free PH80 for women's health indications, including vasomotor symptoms (hot flashes) due to menopause." Fasedienol Nasal Spray for Acute Treatment of Social Anxiety Disorder (SAD) To complement Vistagen’s successful PALISADE-2 Phase 3 trial of fasedienol for the acute treatment of SAD, the Company’s PALISADE-3 trial, anticipated to initiate during the first half of 2024, as well as its PALISADE-4 trial, which is anticipated to be initiated in the second half of 2024, will be U.S. multi-center, randomized, double-blind, placebo-controlled Phase 3 trials designed to evaluate the efficacy, safety, and tolerability of the acute administration of fasedienol to relieve anxiety symptoms in adult patients with SAD, after administration of a single dose of fasedienol during a public speaking challenge in a clinical setting, as measured using the patient-reported Subjective Units of Distress Scale (SUDS) as the primary efficacy endpoint. Vistagen believes either PALISADE-3 or PALISADE-4, if successful, together with the positive results from PALISADE-2, may establish substantial evidence of the effectiveness of fasedienol in support of a potential fasedienol U.S. New Drug Application (NDA) submission for the acute treatment of anxiety in adults with SAD. Itruvone Nasal Spray for Major Depressive Disorder (MDD) Leveraging a successful exploratory Phase 2A trial of itruvone for the treatment of MDD, preparations and planning are underway for Phase 2B development. PH80 Nasal Spray for Vasomotor Symptoms (Hot Flashes) due to Menopause and other Women’s Health Indications Expanding upon successful exploratory Phase 2A trials of PH80 in two women’s health indications, preparations and planning are underway for U.S. IND-enabling nonclinical studies to facilitate U.S. Phase 2B development of hormone-free PH80 for the treatment of vasomotor symptoms (hot flashes) due to menopause and, potentially, premenstrual dysphoric disorder (PMDD). Fiscal Year 2024 Third Quarter Financial Results Research and development (R&D) expense: R&D expense was $4.5 million and $6.9 million for the three months ended December 31, 2023 and 2022, respectively. The decrease in R&D expense was primarily due to a decrease in clinical and development expenses related to the timing of expenses incurred for the Company’s Phase 3 trials of fasedienol in SAD. General and administrative (G&A) expense: G&A expense was $3.8 million and $3.1 million for the three months ended December 31, 2023 and 2022, respectively. The increase was primarily due to increases in compensation and related expenses. Net loss: Net loss was $6.3 million and $9.8 million for the three months ended December 31, 2023, and 2022, respectively. Cash position: At December 31, 2023, the Company had cash and cash equivalents of approximately $126.6 million. As of February 12, 2024, the Company had 27,029,731 shares of common stock issued and 3,577,240 pre-funded warrants outstanding.

About Vistagen Vistagen (Nasdaq: VTGN) is a late clinical-stage biopharmaceutical company pioneering neuroscience to deliver first-in-class therapies for psychiatric and neurological disorders. Five of Vistagen’s six clinical-stage product candidates belong to a new class of drugs known as pherines, which have the potential to rapidly deliver meaningful efficacy with a differentiated safety profile. Pherines are investigational neuroactive nasal sprays with innovative proposed mechanisms of action that activate chemosensory neurons in the nasal passages to impact fundamental neural circuits in the brain without the need for systemic absorption or binding to receptors in the brain. Vistagen’s sixth clinical-stage product candidate, AV-101, is an investigational oral drug candidate with the potential to inhibit, but not block, NMDA receptor activity. Vistagen is passionate about transforming what is possible in the treatment of anxiety, depression, and other neuroscience disorders. Connect at .
