Green Valley Pharmaceutical Suspends Production of Controversial Alzheimer's Drug GV-971 Amid License Renewal
- Green Valley Pharmaceutical has suspended production and sales of GV-971, China's first indigenous Alzheimer's therapy, after its license expired and entered regulatory review.
- The seaweed-derived compound sodium oligomannate received conditional approval in 2019 but faced criticism from medical experts over inconsistent clinical trial results and short study duration.
- Hospital and retail sales of GV-971 reached $45.4 million in 2022, while China's dementia patient population represents 17 million people, about 30% of the global total.
- The company's global clinical trial launched in 2020 was terminated in 2022 due to funding shortages and COVID-19 pandemic disruptions.
