These Superhumans Are Real and Their DNA Could Be Worth Billions - Bloomberg Business

Steven Pete can put his hand on a hot stove or step on a piece of glass and not feel a thing, all because of a quirk in his genes. Only a few dozen people in the world share Pete's congenital insensitivity to pain. Drug companies see riches in his rare mutation. They also have their eye on people like Timothy Dreyer, 25, who has bones so dense he could walk away from accidents that would leave others with broken limbs. About 100 people have sclerosteosis, Dreyer's condition.

Both men's apparent superpowers come from exceedingly uncommon deviations in their DNA. They are genetic outliers, coveted by drug companies Amgen, Genentech, and others in search of drugs for some of the industry's biggest, most lucrative markets.

Their genes also have caused the two men enormous suffering. Pete's parents first realized something was wrong when, as a teething baby, their son almost chewed off his tongue. "That was a giant red flag," says Pete, now 34 and living in Kelso, Wash. It took doctors months to figure out he had congenital insensitivity to pain, caused by two different mutations, one inherited from each parent. On their own, the single mutations were benign; combined, they were harmful.

Dreyer, who lives in Johannesburg, was 21 months old when his parents noticed a sudden facial paralysis. Doctors first diagnosed him with palsy. Then X-rays revealed excessive bone formation in his skull, which led to a diagnosis of sclerosteosis. Nobody in Dreyer's family had the disorder; his parents both carried a single mutation, which Dreyer inherited.

Dreyer and Pete are "a gift from nature," says Andreas Grauer, global development lead for the osteoporosis drug Amgen is creating. "It is our obligation to turn it into something useful."

What's good for patients is also good for business. The painkiller market alone is worth $18 billion a year. The industry is pressing ahead with research into genetic irregularities. The U.S. Food and Drug Administration is expected to approve a cholesterol-lowering treatment on July 24 from Sanofi and Regeneron Pharmaceuticals based on the rare gene mutation of an aerobics instructor with astoundingly low cholesterol levels. Amgen has a similar cholesterol drug, based on the same discovery, and expects U.S. approval in August. The drugs can lower cholesterol when statins alone don't work. They are expected to cost up to $12,000 per patient per year and bring in more than $1 billion annually.

"Before a lot of us participated in these projects, very little about pain itself was known"

Experts Urge Sparing Use of Nonaspirin Painkillers - The New York Times

The Food and Drug Administration warned last week that the risk of heart attack and stroke from widely used painkillers that include Motrin IB, Aleve and Celebrex but not aspirin was greater than it previously had said. But what does that mean for people who take them?

Experts said that the warning reflected the gathering evidence that there was risk even in small amounts of the drug, so-called nonaspirin, nonsteroidal anti-inflammatory drugs, or Nsaids, and that everyone taking them should use them sparingly for brief periods. Millions of Americans take them.

"One of the underlying messages for this warning has to be there are no completely safe pain relievers, period," said Bruce Lambert, director of the Center for Communication and Health at Northwestern University, who specializes in drug safety communication.

But the broader context is important. The relative risk of heart attack and stroke from the drugs is still far smaller than the risk from smoking, having uncontrolled high blood pressure or being obese. At the same time, use of the drugs by someone with those other habits and conditions could compound the risk.

"The additional risk is relatively small, but it could be the straw that breaks the camel's back for someone already at risk," Professor Lambert said. The evidence that the drugs increase the risk of heart attack, stroke and heart failure "is now extremely solid," he said.
