FDA Advisory Committee News
On May 14, 2012, the FDA Peripheral and Central Nervous System Drugs Advisory Committee met to discuss new drug application (NDA) 202737 for tafamidis meglumine capsules, proposed trade name VYNDAQEL, submitted by FoldRx Pharmaceuticals, Inc. a subsidiary of Pfizer, Inc. The proposed indication is for the treatment of transthyretin (TTR) familial amyloid polyneuropathy (FAP).
FAP is caused by a mutation in the gene that codes for TTR. Currently, the treatment of choice in the United States is liver transplant, because TTR is primarily synthesized in the liver.
The sponsor’s assertion is that the tafamidis-induced stabilization of TTR can successfully treat the symptoms of FAP.

NINDS Research Provides Clues to Late-Onset Alzheimer’s Disease
Researchers may have discovered a mechanism behind the largest known genetic risk factor for late-onset Alzheimer's disease. The finding suggests possible strategies for prevention as well as a potential new drug target.
A hallmark of Alzheimer’s is a protein fragment called beta-amyloid, which is thought to be toxic and forms clumps within the brain. Past studies have revealed genetic risk factors for Alzheimer's disease. A gene called APOE has shown the strongest connection to the late-onset form of the disease.
A research team led by Dr. Berislav Zlokovic of USC studyied several lines of genetically engineered mice. One lacks the mouse version of the APOE gene altogether, and 3 other lines produce only human APOE2, APOE3, or APOE4. The study was funded by NINDS and NIA. The researchers discovered that mice whose bodies made only APOE4, or no APOE at all, had a leaky blood-brain barrier. With the barrier compromised, harmful proteins in the blood made their way into the mice's brains.
The researchers found that APOE2 and APOE3 help control the levels of an inflammatory molecule called cyclophilin A (CypA), but APOE4 does not. Levels of CypA were raised about 5-fold in the blood vessels of mice that produce only APOE4. The excess CypA activated an enzyme called MMP-9, which destroys parts of the blood-brain barrier.
Treating the mice with the immunosuppressant drug cyclosporine A, which inhibits CypA, preserved the integrity of the blood-brain barrier and lessened damage to the brain. An inhibitor of the MMP-9 enzyme had similar effects.
These findings identify CypA as a potential new drug target for Alzheimer's disease. They also suggest that one approach to preventing Alzheimer's disease among APOE4 carriers may be to work on improving vascular health.
