VistaGen Therapeutics(US:VTGN)2025-02-13 22:25Clinical Development and Efficacy - Fasedienol, the lead clinical-stage product candidate, is in an ongoing U.S. registration-directed Phase 3 clinical development program for the acute treatment of social anxiety disorder (SAD) [77]. - The PALISADE-2 Phase 3 trial reported a statistically significant difference in mean Subjective Units of Distress Scale (SUDS) scores, with fasedienol-treated patients showing a mean change of -13.8 compared to -8.0 for placebo (p=0.015) [80]. - 37.7% of fasedienol-treated patients were rated as responders on the Clinical Global Impressions – Improvement (CGI-I) scale, compared to 21.4% for placebo (p=0.033) [80]. - The PALISADE-2 trial also demonstrated that 40.6% of fasedienol-treated patients were rated as responders on the Patient's Global Impression of Change (PGI-C) scale, versus 18.6% for placebo (p=0.003) [80]. - Fasedienol was well-tolerated with no serious adverse events reported, and treatment-emergent adverse events were comparable between fasedienol and placebo [80]. - The ongoing PALISADE-3 and PALISADE-4 Phase 3 trials aim to further evaluate the efficacy and safety of fasedienol in adults with SAD [81]. - The company aims for fasedienol to be the first FDA-approved acute treatment for SAD, addressing a significant unmet medical need [78]. - The PALISADE Phase 3 Program includes randomized, double-blind, placebo-controlled trials designed to measure anxiety relief during a public speaking challenge [79]. - Fasedienol's proposed mechanism of action is fundamentally differentiated from existing FDA-approved anti-anxiety medications, potentially offering rapid-onset effects without systemic absorption [77]. - Itruvone demonstrated a significant reduction in depressive symptoms as early as one week at a 6.4 microgram dose, with a p-value of 0.022 compared to placebo [88]. - In a Phase 2A clinical trial, Itruvone was well-tolerated with no reported treatment-related serious adverse events (SAEs) or discontinuations due to adverse events [88]. - PH80 significantly reduced the daily number of hot flashes from a baseline mean of 7.7 to 2.8 after one week of treatment, and to 1.5 after four weeks, with a p-value of less than 0.001 compared to placebo [93]. - PH80 demonstrated statistically significant improvement in PMDD symptoms as early as Day 4 with a p-value of 0.008 compared to placebo [97]. - PH15 showed a statistically significant improvement in reaction time compared to placebo and caffeine, with p-values of less than 0.001 in sleep-deprived participants [101]. - In the Phase 2A pilot study, PH15 induced a significantly faster mean reaction time across all time points compared to placebo, demonstrating its potential efficacy [102]. - PH284 demonstrated a 71% improvement in Subjective Feeling of Hunger scores compared to baseline in a Phase 2A study, indicating potential efficacy in treating cancer cachexia [107]. Regulatory Designations - The FDA has granted Fast Track designation for the investigation of fasedienol for the acute treatment of SAD [83]. - The FDA granted Fast Track designation for the investigation of Itruvone for the treatment of MDD, indicating its potential importance in addressing unmet medical needs [89].
