Will Drug Help Patients With Alzheimer’s?

Ampakine, the drug that helped rats learn and remember in experiments conducted at UC Irvine, has a long way to go before it can be prescribed for humans.

Developers hope the drug will reduce memory loss in mild cases of dementia, such as early Alzheimer’s disease. JoAnn McConnell of the Alzheimer’s Assn. says it’s “very theoretical” that the drug will help Alzheimer’s patients. “The big problem in Alzheimer’s is the (brain) cells are dying,” McConnell said. “Even if you improve communication between them, it isn’t going to prevent them from dying.”

Tests on humans are expected to begin in mid-1994.

The drug--developed by brain scientists Gary Lynch of UCI, Gary Rogers of UC Santa Barbara and Ursula Staubli of New York University--creates a new class believed to work directly on the brain process that creates memory. Cognex, the only drug now approved for treatment of Alzheimer’s disease, works indirectly by blocking enzymes that destroy substances needed for memory.

Allan A. Steigrod, president of Cortex Pharmaceuticals of Irvine, said that even if all tests are successful it will be “at least five years” before his firm can market the drug.

Cortex is developing the drug under license from the University of California. The firm, created in 1987, includes Lynch and two other UCI professors--Carl W. Cotman and Ralph A. Bradshaw--among its founders.
