BioVie Highlighted ADDRESS-LC Phase 2 Trial Design Exploring Bezisterim for the Treatment of Neurological Symptoms of Long COVID at Keystone Symposia on Long COVID and Other Post-Acute Infection Syndromes

CARSON CITY, Nev., Aug. 13, 2025 (GLOBE NEWSWIRE) -- BioVie Inc. (NASDAQ: BIVI) (“BioVie” or the “Company”), a clinical-stage company developing innovative drug therapies for neurological and neurodegenerative diseases, today announced that a poster highlighting the design and enrichment strategy of its ongoing Phase 2 ADDRESS-LC trial will be presented at the Keystone Symposia on , held August 10–13 in Santa Fe, New Mexico.  

Long COVID is now recognized as a leading neurological condition that has affected an estimated 400 million individuals worldwide,^{1,2 .}The Centers for Disease Control has reported that 6.9% of adults in the United States (more than 18 million individuals) currently or previously had long COVID.³ The neurological symptoms such as persistent cognitive dysfunction and fatigue can last for years and currently there are no FDA-approved treatment options.^2,4 ADDRESS-LC (NCT06847191; ) is currently-enrolling participants for a phase 2, multicenter, double-blind, randomized, placebo-controlled, 16-week study evaluating the efficacy, safety, and tolerability of bezisterim in adult participants with Long COVID who are enriched for cognitive impairment and fatigue. The Phase 2 study is fully funded by a grant from the U.S. Department of Defense (DOD).

Bezisterim is an anti-inflammatory agent being developed for Long COVID and other neurodegenerative diseases including Alzheimer’s disease (AD) and Parkinson’s disease (PD), in which TLR-driven inflammation contributes to cognitive decline. It has been shown to inhibit both TLR4-induced signaling and inflammatory NF-κB signaling,⁴ and is orally available, not immunosuppressive, and crosses the blood-brain barrier.^5,6 In clinical trials of AD and PD, bezisterim has demonstrated a favorable safety and tolerability profile.   

"The ADDRESS-LC trial was designed with input from Long COVID patients with the goal of helping to address the tremendous unmet needs of this community," said Penelope Markham, PhD, Senior Vice President of BioVie’s Liver Disease and Long COVID Programs, who will be presenting the design. "Ongoing neuroinflammation has been observed in many patients with Long COVID, and BioVie leveraged its experience in studying other neurodegenerative diseases characterized by inflammation to create a unique trial that will both rigorously evaluate bezisterim in patients and add to our understanding of Long COVID pathology as a whole”.  

The ADDRESS-LC trial features a novel design informed by direct input from clinicians and patients, incorporating pragmatic elements to enhance relevance and feasibility. The study employs an enrichment strategy to increase the likelihood of signal detection and stratifies participants by symptom duration (<2 years or ≥2 years) to account for potential development of refractory symptoms, as well as by age (18–45 or 46–64) to address age-related differences in cognition. Key endpoints include the change in performance on a bespoke Cogstate Cognitive Battery, an objective tool designed to assess bezisterim’s potential to improve neurocognitive symptoms such as cognitive impairment associated with Long COVID. 

Details for the oral and poster presentations are as follows:

About Bezisterim         

Bezisterim (NE3107) is an orally bioavailable, blood-brain barrier (BBB)-permeable modulator of inflammation and insulin-sensitizer. In addition, it is not immunosuppressive and has a low risk of drug-drug interaction. 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 Alzheimer’s disease, Parkinson’s disease and long COVID. 

In Parkinson’s disease, BioVie is currently enrolling patients in the Phase 2  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  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 (Alzheimer’s disease, Parkinson’s disease and long COVID) 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-κB, and the associated neuroinflammation and insulin resistance but not ERK and NFκB 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 .
