Despite growing recognition of long COVID as a serious condition, diagnosed patients have no approved treatment options, with many suffering from debilitating fatigue and brain fog Evidence suggests sustained inflammation plays a central role in the pathogenesis of long COVID, particularly in the associated cognitive dysfunction and other neurological symptoms1 Bezisterim targets key underlying mechanisms of neuroinflammation, and has demonstrated the potential to reduce chronic symptoms in Alzheimer’s disease and Parkinson’s disease trials thought to be driven by neuroinflammation CARSON CITY, Nev., May 15, 2025 (GLOBE NEWSWIRE) -- BioVie Inc. (NASDAQ: BIVI), (“BioVie” or the “Company”), a clinical-stage company developing innovative drug therapies for the treatment of neurological and neurodegenerative disorders and advanced liver disease, today announced first patient enrollment in the Phase 2 ADDRESS-LC clinical trial (NCT06847191) evaluating bezisterim (NE3107) for the treatment of neurological symptoms associated with long COVID. The Company anticipates topline data to be available in the first half of 2026. Long COVID affects approximately 20 million adults in the US, and millions more worldwide.2,3 Studies estimate that approximately 10-30% of individuals who contract COVID-19 experience lingering symptoms for months or even years, with fatigue, brain fog, and cognitive impairment significantly impacting daily functioning and quality of life.4,5 Despite the growing recognition of long COVID as a serious condition, treatment options remain limited, and many patients struggle to find effective relief for their symptoms.4,5 “Bezisterim has demonstrated the ability to modulate key inflammatory pathways implicated in the chronic inflammation seen in long COVID, that also play a key role in neurodegenerative diseases of aging, like Parkinson’s and Alzheimer’s. By reducing neuroinflammation and addressing potential metabolic dysfunction, our hope is that bezisterim may have the potential to help patients with long COVID,” stated Cuong Do, BioVie’s President and CEO. “This trial will explore whether targeting these mechanisms can help restore normal function and improve quality of life for individuals affected by the neurological symptoms of long COVID, and we look forward to sharing our findings in the first half of 2026.” The Phase 2 ADDRESS-LC study, which is fully funded by a grant from the U.S. Department of Defense (DOD), is a randomized (1:1), placebo-controlled, multicenter trial evaluating the efficacy, safety and tolerability of bezisterim in adult participants with long COVID who have cognitive impairment sequelae and fatigue. Individuals who have been diagnosed with long COVID and have neurocognitive dysfunction and self-reported fatigue may meet qualification criteria and can visit www.addressLC.com to learn more. “Long COVID remains a significant and poorly understood health challenge, with many patients experiencing persistent neurological and systemic symptoms long after their initial infection. Emerging evidence suggests that sustained inflammation plays a central role in the pathogenesis of long COVID, particularly in cognitive dysfunction and other neurological impairments,” stated Lindsay McAlpine, MD, BSc, a neuroimmunologist in the Division of Neurological Infections and Global Neurology at the Yale University School of Medicine. “SARS-CoV-2 proteins have been shown to persist in the body. We know triggered inflammatory pathways resulting from a SARS-CoV-2 infection can affect the blood-brain barrier, leading to prolonged neuroinflammation and associated symptoms. Given that variants in these pathways have been linked to severe and long-lasting cases of long COVID, there is a pressing need for targeted interventions that can disrupt this inflammatory cascade.” About Long COVIDLong COVID is a condition in which symptoms of COVID-19, the acute respiratory disease caused by the SARS-CoV-2 virus, persist for an extended period, generally three months or more. Common symptoms include lingering loss of smell and taste, extreme fatigue, and “brain fog,” though persistent cardiovascular and respiratory problems, muscle weakness, and neurologic issues have also been documented. Approximately 20 million individuals in the U.S. currently or previously have long COVID, with millions more impacted worldwide.2,3 The loss in quality of life and earnings and increased medical costs has an enormous economic impact estimated to be $3.7 trillion.6 To date there are no non-pharmacological or pharmacological therapies proven effective for treatment of long COVID. About BezisterimBezisterim (NE3107) is an orally bioavailable, blood brain barrier-permeable, insulin-sensitizer that is also anti-inflammatory. In addition, it is not immunosuppressive and has a low risk of drug-drug interactions. By binding to ERK and selectively modulating NFκB activation and TNF-α production, BioVie believes that bezisterim may offer clinical improvements in several disease indications, including Parkinson’s Disease (“PD”), Alzheimer’s Disease (“AD”) and long COVID. In Parkinson’s disease, BioVie is currently enrolling patients in the Phase 2 SUNRISE-PD clinical trial evaluating the safety and efficacy of bezisterim on motor and non-motor symptoms in patients who have not been treated with carbidopa/levodopa, with topline data expected in late 2025 or early 2026. A previous Phase 2 study of bezisterim in Parkinson’s disease (NCT05083260) completed in 2022, and data presented at the AD/PD™ 2023 International Conference on Alzheimer’s and Parkinson’s Diseases and related neurological disorders in Gothenburg, Sweden in March 2023 showed significant improvements in “morning on” symptoms and clinically meaningful improvement in motor control in patients treated with a combination of bezisterim and levodopa versus patients treated with levodopa alone, and no drug-related adverse events. In long COVID, bezisterim has the potential to reduce neurological symptoms including fatigue and cognitive dysfunction. Persistently circulating viral spike proteins are believed to trigger TLR-4 driven activation of NFκB and the subsequent expression of inflammatory cytokines (IL-6, TNF, IFNg). BioVIe’s Phase 2 ADDRESS-LC study, is a randomized (1:1), placebo-controlled, multicenter trial in approximately 200 patients to evaluate the safety, tolerability and potential efficacy of 3 months of treatment with bezisterim to reduce the neurocognitive symptoms associated with long COVID, including difficulty concentrating or remembering things (“brain fog”) and fatigue. In Alzheimer's disease, BioVie conducted and reported efficacy data on its Phase 3 randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate bezisterim in patients who have mild-to-moderate Alzheimer’s disease (NCT04669028) in 2023. Results of a Phase 2 investigator-initiated trial (NCT05227820) showing bezisterim-treated patients experienced improved cognition and biomarker levels were presented at the Clinical Trials on Alzheimer’s Disease (CTAD) annual conference in December 2022. An estimated six million Americans suffer from Alzheimer’s disease.

About BioVie Inc. BioVie Inc. (NASDAQ: BIVI) is a clinical-stage company developing innovative drug therapies for the treatment of neurological and neurodegenerative disorders (Long COVID, Alzheimer's disease and Parkinson’s disease) and advanced liver disease. In neurodegenerative disease, the Company’s drug candidate bezisterim inhibits inflammatory activation of extracellular signal-regulated kinase and the transcription factor, Nuclear factor- kB, and the associated neuroinflammation and insulin resistance but not ERK and NFkB homeostatic functions (e.g., insulin signaling and neuron growth and survival). Both neuroinflammation and insulin resistance are drivers of AD and PD. Persistent systematic inflammation and neuroinflammation are key features in patients with neurological symptoms of Long COVID. In liver disease, the Company’s Orphan drug candidate BIV201 (continuous infusion terlipressin), with FDA Fast Track status, is being evaluated and discussed with guidance received from the FDA regarding the design of Phase 3 clinical testing of BIV201 for the reduction of further decompensation in participants with liver cirrhosis and ascites. The active agent is approved in the U.S. and in about 40 countries for related complications of advanced liver cirrhosis. For more information, visit www.bioviepharma.com.
