Thank you, Mark and good afternoon everyone. On behalf of our entire team at VistaGen thank you for joining this call. We sincerely hope you and those who are important to you are doing well both physically and mentally. Taking care of your mental health is essential at every stage of life. And as we enter into the third year of the COVID-19 pandemic, it’s safe to say that at one point or another everyone’s mental well-being may have been impacted in some manner. And even before the pandemic, anxiety and depression disorders represented large and accretive global markets with unsatisfied medical needs. And now perhaps more so than ever before, innovative treatments for anxiety and depression disorders are needed to improve the lives of millions of individuals around the world who are suffering from these mental health conditions. Our team is on task and is working tirelessly to develop much needed novel treatments with the potential to deliver rapid onset beliefs or relief without the negative side effects and safety concerns of current medications. Our third quarter results reflect notable progress across our pipeline and all other aspects of our business. During calendar ‘22, we anticipate key top line Phase 3 data readouts with exciting potential to transform major aspects of mental healthcare. Our PALISADE Phase 3 program is designed to further demonstrate potential of PH94B as a rapid onset, as needed, acute treatment of anxiety in adults with social anxiety disorder or SAD. Our two ongoing Phase 3 studies in the program, PALISADE-1 and PALISADE-2 and our PALISADE long-term safety study are on track, where top line data readout is previously anticipated. Specifically, PALISADE-1 is expected to deliver top line results midyear this year and PALISADE-2 is expected to deliver top line results in the second half of this year. Should they be successful, we anticipate that these studies and a couple of smaller studies will anchor our U.S. new drug application for PH94B in SAD. In addition to the milestones we achieved in our PALISADE Phase 3 program during the recent quarter, we launched our Phase 2a clinical study of PH94B in adjustment disorder with anxiety is the first study in our exploratory clinical evaluation program for PH94B and anxiety indications beyond SAD. With emotional stress and impaired functioning brought on by sudden change in health, safety and economic and social circumstances that many have experienced at heightened level since the beginning of the pandemic, the need for an innovative therapy for adjustment disorder with anxieties become increasingly apparent to our team and the clinicians in our ecosystem. We believe PH94B has the potential to offer relief to the growing number of individuals whose routine daily functioning has been impaired by the onset or exacerbation of adjustment disorder with anxiety. We anticipate top line results for this Phase 2a study in the second half of ‘22. Later this year, we also plan to initiate additional small exploratory clinical studies to assess PH94B’s potential in populations suffering from anxiety disorders beyond both SAD and adjustment disorder indications, where we believe the current treatment alternatives are inadequate. Also, during the quarter, we reported important new preclinical data on PH94B’s potential mechanism of action or MOA. Data from a tissue distribution study in laboratory rats demonstrated that a single intranasal administration of radiolabeled PH94B was largely confined to the nasal passages with minimal or undetectable levels in most other tissues, including the CNS. More importantly, no appreciable activity was observed in the brain. We believe these results further highlight the fundamental difference in PH94B’s MOA compared to that of all current anxiety therapies. When the data from this radiolabeled PH94B tissue distribution study is combined with that from previous in vitro studies demonstrating that the MOA of PH94B does not involve direct activation of GABA A receptors, we see a growing body of evidence suggesting that PH94B has the potential to achieve rapid anti-anxiety effects without requiring systemic uptake or causing benzodiazepine-like side effects or other safety concerns. Regarding our other clinical stage drug candidates, we are preparing to initiate a Phase 2b clinical study of PH10 as a potential rapid onset standalone treatment in major depressive disorder. In the second half of ‘22, we believe PH10 is potential across multiple depression disorders. Also during the quarter, we initiated a Phase 1b trial for oral pro drug candidate AV-101 in combination with an FDA-approved probenecid. The study follows two positive preclinical studies showing that the combination of AV-101 and probenecid substantially increased the brain concentration of the active metabolite of AV-101 targeted at reducing rather than blocking NMDA receptor signaling. We believe AV-101 in combination with probenecid has the potential to be developed as an innovative treatment for several CNS conditions involving the NMDA receptor. I would now like our CFO, Jerry Dotson to summarize some of the highlights from our fiscal 2022 third quarter financial results. Jerry?
