New Drug Stalls Alzheimer's Development in Breakthrough Trial - ScienceAlert

New Drug Stalls Alzheimer's in Groundbreaking Trial

Scientists have unveiled NU-9, a promising compound that halts Alzheimer's progression in its earliest phases, offering hope for millions. Tested on mouse models by Northwestern University researchers, NU-9 dramatically reduces toxic amyloid beta oligomers, preventing plaque formation and calming inflamed brain cells like astrocytes. This breakthrough underscores the critical need for early intervention, as growing evidence shows treatments work best before symptoms emerge.[2]

Why Early Detection Matters

Catching Alzheimer's via advanced biomarkers—such as blood tests and brain imaging—could enable pre-symptomatic use of drugs like NU-9. Similar to FDA-approved lecanemab and donanemab, which slow decline by up to 30-60% in early stages, NU-9 targets root causes of neuroinflammation. Experts predict combining these with prophylactics for high-risk groups will transform outcomes, buying time for normal living.[1][5]

Future Horizons

Ongoing trials explore NU-9 in later-stage models, alongside innovations like focused ultrasound for plaque reduction and novel receptor-targeting drugs. These advances signal a shift toward preventive strategies, potentially stopping cognitive loss before it starts and paving the way for broader neurodegenerative treatments.[3][4]

FDA

## Overview The **U.S. Food and Drug Administration (FDA)** is a federal agency within the Department of Health and Human Services responsible for protecting public health by ensuring the safety, efficacy, and security of a wide range of products, including human and veterinary drugs, biologics, medical devices, food, cosmetics, and products that emit radiation[1][2][3]. Its mission is to advance public health by helping to speed innovations that make medical products safer, more effective, and more affordable, while providing the public with accurate, science-based information about these products[1]. ## Functions and Regulatory Scope The FDA’s regulatory authority is expansive. It oversees the approval, manufacturing, marketing, and distribution of prescription and over-the-counter drugs, vaccines, blood products, medical devices (from simple tongue depressors to complex pacemakers), dietary supplements, most foods (except some meat, poultry, and egg products regulated by the USDA), cosmetics, and tobacco products[1][2][5]. The agency also regulates electronic products that emit radiation, such as X-ray machines and microwave ovens[2][5]. Importantly, the FDA does not regulate the practice of medicine, medical services, product pricing, or health insurance reimbursement[2]. The FDA achieves its goals through a combination of **premarket reviews**, **post-market surveillance**, **facility inspections**, **enforcement actions**, and **public education**[3][4]. It maintains several adverse event reporting systems—such as MedWatch and VAERS—to monitor product safety after they reach the market[4]. The agency also plays a key role in the nation’s counterterrorism efforts by ensuring food supply security and fostering the development of medical countermeasures[1]. ## History and Key Achievements Established in 1906 with the passage of the Pure Food and Drugs Act, the FDA’s origins trace back to efforts to combat adulterated and misbranded food and drugs. Its regulatory powers expanded significantly with the
