Resumen de: WO2026064441A1
The disclosure is related to methods of treating a subject with Alzheimer's Disease (AD) using anti-amyloid beta (Aβ) therapy. The patient may be treated based on the measurement and analysis of biomarker levels, such as plasma Aβ42/40 ratio, pTau181 and pTau217. The disclosure includes a systematic approach called CP Convert for converting biomarker measurements across different analytical platforms, enabling comparison of pTau217 data from LC-MS/MS, SIMOA, and chemiluminescent enzyme immunoassay platforms. Methods demonstrate that pTau217 has superior diagnostic accuracy compared to Aβ42/40 ratio and pTau181 for detecting brain amyloid positivity. Implementation of pTau217 prescreening can significantly reduce Aβ-PET testing, decreasing patient burden and clinical trial costs. The CP Convert methodology can be validated using independent cohorts, demonstrating robust cross-platform conversion for research applications.
