Making medical care more effective

A $60 million South Florida-led study hopes to find out how our difference­s affect our health treatment.

South Florida’s ethnic diversity will play a key role in an ambitious, five-year medical research effort aimed at making treatments and drugs more effective by tailoring them to the lifestyles, genetics and environmen­t of individual patients.

Led by the University of Miami’s Miller School of Medicine and funded by a $60 million grant from the National Institutes of Health, a group of academic institutio­ns in Florida and Georgia — including the University of Flor- ida, Emory University, and Morehouse School of Medicine — have begun to recruit 100,000 people from the Southeaste­rn United States to participat­e in a nationwide research program called “All of Us.”

The program’s goal is to recruit one million or more U.S. residents over the next five years — including 40,000 from South Florida — to help create a rich pool of data that will account for individual difference­s in genetics, behavior and geography in biomedical research. That database will then be used for future studies into a wide variety of health conditions and to hel psci entists develop more precise medical interventi­ons.

Until now, most biomedical research has been conducted primarily with non-Hispanic white subjects, mostly men, though the U.S. Census shows that minori- ties make up nearly 40 percent of the population.

“It’s not enough to study just one kind of people,” said Dr. Stephan Züchner, principal investigat­or for the All of Us program’s SouthEast Enrollment Center and chair of UM’s Department of Human Genetics. “It’s very important that we understand the genomes of all people on the planet.”

For instance, he said, people from Southeast Asia tend to have fast metabolism­s, which causes certain drugs to have little or no effect on them.

“In Mexico,” he said, “there’s a much higher risk to develop diabetes. We don’t know why. But it might well have to do with genetics.” Similarly, Züchner added, “We cannot treat African Americans accordingl­y if we do not

realize they have a higher risk for certain cardiovasc­ular disorders.”

The program is open to all adults, regardless of race or ethnicity, health status, education or income level. Anyone interested in participat­ing can sign up through the All of Us online portal at joinallofu­s.org/en.

Those selected will receive genomic sequencing. But scientists want to understand more than genetics. They want to figure out how individual behaviors, such as exercising, smoking or overeating, and a person’s environmen­t, from the climate to the availabili­ty of fresh fruits and vegetables, affect the way genetics function, said Dr. Olveen Carrasquil­lo, a lead researcher for the program and an internal medicine physician with the UM Health System.

“Health is composed of many things,” he said. “But we don’t know the right balance of these things and how they contribute to health and health outcomes.”

Carrasquil­lo said the All of

Us program will follow participan­ts for at least five years and collect a wide range of data from them, including any diagnosed diseases, medication­s they’re taking and diet, with the aim of helping researcher­s one day figure out what medicines work best for individual patients based on their unique traits.

“It’s a much more nuanced approach to treatment that’s really much more targeted for that individual person,” Carrasquil­lo said.

The NIH and researcher­s will hold conference­s over the coming years to decide next steps for studying participan­ts. One idea that has gained traction is using technology, such as wearable activity trackers and electronic health records, to measure participan­ts’ behaviors and gather their informatio­n.

Züchner said patient data collected as part of the All of Us program will be safeguarde­d and used only by researcher­s. “This is as good as it gets when it comes to data protection,” he said.

Studying a million people also may produce better research results than prior studies because of the unpreceden­ted scale, Züchner said. And though he expects it will take a decade or longer before biomedical researcher­s can make good use of the data — perhaps too long for participan­ts to benefit personally — Züchner believes the effort will be worth it in the long run.

“It’s almost like you invest a little bit, you give a little bit of your personal data,” he said, “so your children and your family will benefit from it.”
