People with type 2 diabetes are at increased risk for heart attacks, stroke, and other forms of cardiovascular disease, and at an earlier age than other people. Several years ago, the Food and Drug Administration (FDA) recommended that drug developers take special care to show that potential drugs to treat diabetes don’t adversely affect the cardiovascular system . The challenge in implementing that laudable exhortation is that a drug’s long-term health risks may not become clear until thousands or even tens of thousands of people have received it over the course of many years, sometimes even decades.
Now, a large international study, partly funded by NIH, offers some good news: proof-of-principle that “Big Data” tools can help to identify a drug’s potential side effects much earlier in the drug development process . The study, which analyzed vast troves of genomic and clinical data collected over many years from more than 50,000 people with and without diabetes, indicates that anti-diabetes therapies that lower glucose by targeting the product of a specific gene, called GLP1R, are unlikely to boost the risk of cardiovascular disease. In fact, the evidence suggests that such drugs might even offer some protection against heart disease.

A new year has arrived, and it’s going to be an amazing one for biomedical research. But before diving into our first “new science” post of 2016, let’s take a quick look back at 2015 and some of its remarkable accomplishments. A great place to reflect on “the year that was” is the journal Science’s annual Top 10 list of advances in all of scientific research worldwide. Four of 2015’s Top 10 featured developments directly benefited from NIH support—including Science’s “Breakthrough of the Year,” the CRISPR/Cas9 gene-editing technique. Here’s a little more on the NIH-assisted breakthroughs:
CRISPR Makes the Cut: I’ve highlighted CRISPR/Cas9 in several posts. This gene-editing system consists of a short segment of RNA that is attached to an enzyme. The RNA is preprogrammed to find a distinct short sequence of DNA and deliver the enzyme, which acts like a scalpel to slice the sequence out of the genome. It’s fast and pretty precise. Although CRISPR/Cas9 isn’t brand-new—it’s been under development as a gene-editing tool for a few years—Science considered 2015 to be “the year that it broke away from the pack.”

Readers of this blog know how excited I am about the potential of precision medicine for revolutionizing efforts to treat disease and improve human health. So, it stands to reason that I’m delighted by the positive reactions of researchers, health professionals, and the public to a much-anticipated report from the Precision Medicine Initiative (PMI) Working Group of the Advisory Committee to the NIH Director. Topping the report’s list of visionary recommendations? Build a national research cohort of 1 million or more Americans over the next three to four years to expand knowledge and practice of precision medicine.
When the President announced PMI during his 2015 State of the Union address, he envisioned a precise new era in medicine in which every patient receives the right treatment at the right time—an era in which health care professionals have the resources at hand to take into account individual differences in genes, environments, and lifestyles that contribute to disease. To achieve this, PMI’s national research cohort would tap into recent advances in science, technology, and research participation policies to build the knowledge base needed to develop individualized care for all diseases and conditions.
