New Migraine Drug Tezampanel in Trouble?

Ellen Schnakenberg at WEGO Health reports that pharmaceutical company TorreyPines Therapeutics has announced its intention to shut down and liquidate its assets.

TorreyPines has been developing a new type of migraine drug called Tezampanel, which is a glutamate reception inhibitor. One of the current theories about migraines involves the observation that people experiencing migraines have an excess of an amino acid known as glutamate. Glutamate naturally occurs in the brain and is essential for healthy people, but too much of it can lead to a number of diseases or conditions. Drugs like Tezampanel act to stop a migraine by blocking glutamate in the brain.

It remains unclear what will now happen to Tezampanel in the wake of TorreyPines' financial failure. Perhaps it will be sold to another pharmaceutical company. Hopefully it will not simply fall by the wayside and fade into obscurity.

Addex Pharmaceuticals also has a drug (ADX10059) in development that works on glutamate, so even if Tezampanel is lost, research in this area can be expected to continue.
