Johnson & Johnson showcases latest advancements in Alzheimer's research at AAIC 2025

Early data from robust Autonomy Phase 2b posdinemab trial demonstrate Company's leadership in multimodal biomarkers and early detection

New findings highlight the central role of tau in disease progression, bolstering confidence in the Company's industry-leading anti-tau portfolio

Featured research session to share new findings from GNPC, the world's largest neurodegenerative disease proteomics resource, co-founded with Gates Ventures

TITUSVILLE, N.J., July 24, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced promising new data from its Alzheimer's disease (AD) research program will be presented at the Alzheimer's Association International Conference (AAIC), taking place July 27–31 in Toronto, Canada. Across 12 abstracts, the Company will share insight into how tau impacts brain function in early AD and reinforce the predictive strength of plasma biomarker pTau217 for tracking cognitive decline in at-risk individuals. The Company will also introduce findings from the Global Neurodegeneration Proteomics Consortium (GNPC), a public-private partnership co-founded by Johnson & Johnson and Gates Ventures, the private office of Bill Gates.

"Our long-standing leadership in Alzheimer's disease research gives us critical perspective on where the field has been and where it needs to go," said Bill Martin, Ph.D., Global Therapeutic Area Head, Neuroscience, Johnson & Johnson. "These data reflect how we are reconceptualizing the way we diagnose and treat disorders that are among the most prevalent and debilitating of our time, underscoring our unmatched legacy of advancing neuroscience and improving lives, and bringing us closer to a future where Alzheimer's disease may one day be a thing of the past."

Following the July 15 publication in Nature Medicine and Nature Aging, and the public release of the GNPC dataset, leaders from Johnson & Johnson and Gates Ventures will host a featured research session at AAIC to share new findings from the world's largest neurodegenerative disease proteomics resource. 

"Long-standing challenges in assembling large, diverse datasets have made progress in understanding the biology of neurodegenerative diseases extremely slow. At AAIC, we are sharing how the GNPC is enabling discovery at scale," said Niranjan Bose, Ph.D., Managing Director, Health & Life Sciences at Gates Ventures. "Even at this early stage, researchers are uncovering new insights into some of the most studied risk factors, highlighting the power of the GNPC to drive discovery, reveal new targets, and ultimately accelerate progress for the more than 57 million people living with Alzheimer's disease and other dementias worldwide."

The following Company-sponsored and Company-partnered abstracts will be presented at AAIC 2025:

ABOUT ALZHEIMER'S DISEASE (AD) & DEMENTIA

Alzheimer's disease (AD), the most common form of dementia worldwide, is a fatal neurodegenerative disorder characterized by progressive memory loss and a decline in other cognitive abilities severe enough to significantly interfere with daily life.¹ Diagnostic criteria for AD are based on established classifications but continue to evolve as research advances. Preclinical AD refers to individuals with detectable AD pathology (amyloid and tau) who are cognitively unimpaired. Early AD includes individuals with mild cognitive impairment due to AD (also known as prodromal AD) and mild Alzheimer's dementia.

As AD advances, patients experience worsening cognitive decline, eventually losing the ability to perform basic tasks, communicate or recognize loved ones, ultimately leading to death.¹ There is no cure for AD, and despite several new advancements, significant unmet need remains across the spectrum of this devastating disease.

ABOUT POSDINEMAB

Posdinemab is an investigational monoclonal antibody that is designed to target the mid-domain of AD-specific phosphorylated tau. Posdinemab is designed to bind to pathological phosphorylated tau when it is released from neurons and neutralize it before it can seed/spread to another neuron. The internally-discovered antibody has shown promise in reducing tau seeding—the process by which toxic tau spreads through the brain—in both in vitro and in vivo non-clinical studies.

The Phase 2b "AuTonomy" study investigating posdinemab in participants with early AD is fully enrolled and ongoing (NCT04619420).
