Key Terms

4 terms

phosphorylated tau 217 (ptau217) medical

"to incorporate ALZpath's proprietary phosphorylated Tau 217 (pTau217) antibody into the development"

Phosphorylated tau 217 (ptau217) is a specific form of the brain protein tau that carries a phosphate tag at the 217th amino acid and can be measured in blood or spinal fluid as a marker of nerve‑cell damage associated with Alzheimer’s pathology. Like a smoke alarm for early disease changes, ptau217 helps clinicians and researchers detect disease, select appropriate patients and track treatment effects, so advances in tests or drugs tied to this marker can drive commercial, clinical and regulatory value.

in vitro diagnostic (ivd) medical

"into the development of an in vitro diagnostic (IVD) test for Alzheimer's disease"

In vitro diagnostic (IVD) tests are medical tests run on samples such as blood, urine or swabs outside the body to detect diseases, measure biomarkers or guide treatment decisions. Investors pay attention because IVDs generate recurring sales for test kits and instruments, are heavily influenced by regulatory approval, reimbursement and accuracy, and can quickly shift market value when a test becomes widely adopted or replaced — like a trusted household tool that professionals rely on every day.

cerebrospinal fluid (csf) medical

"alternative to PET imaging and cerebrospinal fluid (CSF) analysis, which are costly"

Cerebrospinal fluid (CSF) is a clear liquid that surrounds and cushions the brain and spinal cord, providing protection and helping to remove waste. Although it is a medical term, in a financial context, understanding how resources and support flow within a system can be similar to how CSF circulates and maintains the health of the nervous system. Recognizing such fundamental processes can offer insights into the stability and resilience of broader systems, including financial markets.

biomarkers medical

"Blood-based biomarkers may also play a role in monitoring disease progression"

Biomarkers are measurable indicators found in the body, such as substances in blood or tissues, that reveal information about health or disease. For investors, they can signal how well a medical treatment is working or whether a disease is developing, helping to assess the potential success or risks of healthcare companies or innovations. Think of biomarkers as biological signals that provide clues about a person’s health status.

ALZpath Strengthens Market Leadership with Abbott Agreement to Help Enable Early Alzheimer's Diagnosis at Global Scale

CARLSBAD, Calif., June 24, 2026 /PRNewswire/ -- ALZpath Inc., the leader in blood test-based diagnostic solutions for Alzheimer's disease, today announced a licensing agreement with Abbott (NYSE: ABT), a global healthcare leader, to incorporate ALZpath's proprietary phosphorylated Tau 217 (pTau217) antibody into the development of an in vitro diagnostic (IVD) test for Alzheimer's disease. The test would be designed for use on Abbott's Alinity ci-series systems, which represents one of the largest install bases of immunoassay instruments worldwide.

ALZpath's pTau217 antibody is among the most clinically validated for detecting Alzheimer's disease pathology. Backed by more than 200 peer-reviewed publications across 18 countries, the antibody demonstrates high accuracy and sensitivity in identifying Alzheimer's disease biology.

"This agreement further strengthens ALZpath's leadership in blood-based Alzheimer's testing and reinforces our position as the foundational component supporting the overwhelming majority of the pTau217 IVD market," said Mike Banville, CEO of ALZpath. "As blood-based biomarkers become central to how Alzheimer's disease is detected and managed, partnering with a global healthcare leader like Abbott can enable high-performance testing to reach clinicians and patients around the world at scale. Together with our diagnostic partners, we remain focused on bringing our highly accurate and sensitive antibody into routine care, including primary care, to reach patients in need."

As disease-modifying therapies continue to expand, accessible diagnostics are essential for earlier patient identification. ALZpath's pTau217 antibody offers a scalable alternative to PET imaging and cerebrospinal fluid (CSF) analysis, which are costly, invasive, and difficult to deploy at scale. Blood-based biomarkers may also play a role in monitoring disease progression and treatment response in routine clinical practice.

"Abbott has spent more than a decade advancing brain health science to give clinicians earlier, clearer answers," said John Frels, vice president of research and development in Abbott's Core Diagnostics business. "Our work – including pioneering the first FDA cleared rapid blood test that helps assess mild traumatic brain injuries by providing objective biomarker data – shows what's possible when we deepen our understanding of the brain. Collaborations like this are accelerating the next era of Alzheimer's disease research, clinical trials for therapies and ultimately patient care."
