Annovis Announces Novel Biomarker Data in Alzheimer's Patients Supporting Buntanetap's Potential as a Disease-Modifying Treatment

Core Insights - Annovis Bio, Inc. announced new results indicating that its drug candidate, buntanetap, can reduce inflammation and improve cellular health in Alzheimer's patients, suggesting potential disease-modifying effects beyond just symptomatic relief [1][2]. Group 1: Clinical Study Results - The Phase 2/3 study analysis showed that buntanetap effectively targets key biomarkers of neuroinflammation and neurodegeneration, leading to reductions in inflammatory markers such as IL-5, IL-6, S100A12, IFN-γ, and IGF1R compared to placebo [2]. - Buntanetap also decreased levels of neurofilament light chain (NFL), a marker of neuronal damage, indicating improved cellular integrity and neuronal health, particularly in patients with positive pTau217 plasma levels [2][3]. Group 2: Mechanism and Therapeutic Potential - The drug's ability to target multiple neurotoxic proteins simultaneously is highlighted as a significant advantage, potentially interrupting the toxic cascade associated with Alzheimer's disease [3]. - Previous clinical benefits were noted in mild Alzheimer's patients, who experienced significant cognitive improvements, reinforcing the potential of buntanetap as a disease-modifying therapy [3]. Group 3: Ongoing Research and Future Outlook - Buntanetap is currently undergoing a pivotal Phase 3 trial in early Alzheimer's disease, with a 6-month readout focused on symptomatic improvement and an 18-month readout aimed at assessing disease modification [3][4]. - The full biomarker data will be presented at the Clinical Trials on Alzheimer's Disease (CTAD) conference in December 2025, which is expected to provide further insights into the drug's efficacy [4].
