The Chinese equivalent of the FDA, the National Medical Products Administration, has just approved a natural product to treat mild to moderate Alzheimer’s disease. Even the company, Shanghai Green Valley Pharmaceuticals, doesn’t claim the compound will prove to be a cure for Alzheimer’s. However, the US FDA has not approved any drugs to treat Alzheimer’s disease since 2003.
What Is the Evidence for a Possible Cure for Alzheimer’s Disease?
Green Valley Pharmaceuticals derived their new drug, Oligomannate, from seaweed. The company has conducted research in mice that demonstrated the compound can alter the gut microbiome (Cell Research, Sept. 6, 2019). Apparently, this shift is enough to reduce inflammation in the central nervous system.
No one knows whether Oligomannate affects the human microbiome in the same way. However, recent reviews of scientific studies suggest a strong link between the microbiota and neuroinflammation (Frontiers in Aging Neuroscience, Oct. 18, 2019). People with Alzheimer’s disease often have disrupted intestinal microbiota. The authors suggest that this may offer a new target for treating the condition.
The Clinical Trial for Oligomannate:
The Chinese NMPA granted conditional approval for Oligomannate based on a phase 3 clinical trial of more than 800 individuals. After a month, the people receiving the drug had significantly better scores on one standardized cognitive test than those on placebo. This advantage apparently held up for the rest of the time the trial lasted, about eight months. The company is expected to conduct larger, longer-lasting studies to change the conditional approval into ordinary approval.
Will Oligomannate Be Used World-Wide?
Some observers are skeptical. Most national drug regulators, including the FDA, require significant improvement from more than one cognitive test. In addition, they want to see results for more than nine months. Fortunately, the company is planning to recruit volunteers for a study in Europe, the US and elsewhere in Asia. Shanghai Green Valley Pharmaceuticals will use this research to demonstrate whether the drug is safe and effective over the long term. If it is successful, perhaps we can hope that following through on such innovative research may some day yield a cure for Alzheimer’s disease.
