Taking Matters--and Science--Into Their Own Hands

Research * Two brothers are trying to stamp out deadly Lou Gehrig's disease by raising funds and hiring scientists.

Late last year, eight patients with a fatal neurological disorder gathered in Newton, Mass., with their loved ones and a handful of scientists for a crash course: ALS 101.

Their goal: to learn everything they could about amyotrophic lateral sclerosis, also known as Lou Gehrig's disease.

Their instructor was Jamie Heywood, a 34-year-old engineer turned teacher, scientist and pharmaceutical entrepreneur who, in 1998, took his own course when his brother Stephen was diagnosed.

Heywood quit his job at a neuroscience think tank in California and headed home to Massachusetts to take care of his brother. He's now taken on the task of finding a cure for the disease, which strips away the body's motor neurons and leaves its victims trapped inside their bodies. A progressive paralysis takes hold, and patients die within an average of five years of diagnosis, when the motor neurons that guide respiration give out.

"The thing about Jamie," says Stephen, "is that he can be very focused, but not for a long period of time." But as Stephen Heywood's disease has progressed, his older brother's determination has not lost its fire. His efforts remain focused on trying to produce treatments for the 30,000 people diagnosed with ALS--a disease with no known cure.


The Heywoods are a new breed of patient advocates: people who want to speed the science along by raising money that allows researchers to pursue ideas that might not qualify for scarce federal funding. These brothers have gone a step further: They started the ALS Therapy Development Foundation and hired scientists to carry out the studies.

The brothers, supported by their parents, are collaborating on a project called FDA 2000, a plan developed by Harvard's Dr. Steve Gullans to test all 1,500 drugs approved by the U.S. Food and Drug Administration to see if any can work against ALS. This is the first time scientists have taken such an approach.

The goal is a shortcut to an effective ALS drug; the development of new compounds can take more than a decade. So Jamie Heywood became executive director of the foundation and began, in effect, to build a pharmaceutical company from the outside in: hire the scientists, design the studies, stock up on mice. "This is definitely the way to go," he said.

And he knows he's racing against time. "We can now screen thousands of drugs and play it backward. Anything that is promising in mice becomes stunningly important as a candidate in human ALS."


Heywood and his staff--including six scientists--work closely with Gullans, a scientist who turned his attention to ALS when a relative was diagnosed. It was Gullans who proposed the radical approach of "opening the medicine cabinet and testing every drug."

Gullans is funded in his new career by Heywood's organization and Project ALS, another research and advocacy group started by the Estess sisters of New York City, one of whom has ALS. Gullans is hoping that medicines already in the pipeline could have an impact not just on ALS but also on other neurological disorders.

The first round of tests targeted neuronal cells primed to die a death similar to ALS motor neurons. (Motor neurons themselves are too finicky to use in testing.) The scientists identified about 30 promising drugs. Further testing found that eight of the 30 were potent enough to warrant more tests.

That's where Jamie Heywood comes in. He hired the scientists and opened two laboratories in Boston, where hundreds of mice engineered to develop ALS are going to be tested with Gullans' "hit list" of drugs.

Gullans said it is too early to release the names of the medicines.

Already, research data suggest that a massive inflammatory system attack occurs in the diseased motor neurons. Scientists who have analyzed spinal cord tissue from ALS patients have found the same thing: reactive astrocytes and microglia, evidence of an inflammatory process. Gullans and others now believe there is a powerful inflammatory component that could be driving the motor neurons--the cells that crowd the spinal cord and receive messages from the brain that coordinate movement--to death.

When Heywood set out to find a cure for ALS, what he read was discouraging. Many medicines had been tried, all unsuccessfully. Then he read about glutamate transporter protein, which seemed to be missing in the spinal tissue of ALS patients. He called Dr. Jeffrey Rothstein, an ALS researcher at Johns Hopkins Medical Institutes whose work on the gene that produces the glutamate transporter protein convinced Heywood that gene therapy to repair the glutamate transporter system was a potential cure for his brother. An animal study suggested that the concept would work.
