A major part of NIH’s mission is to support basic research that generates fundamental knowledge about the nature and behavior of living systems. Such knowledge serves as the foundation for the biomedical advances needed to protect and improve our health—and the health of generations to come.

Of course, it’s often hard to predict how this kind of basic research might benefit human populations, and the lag time between discovery and medical application (if that happens at all) can be quite long. Some might argue, therefore, that basic research is not a good use of funds, and all of NIH’s support should go to specific disease targets.

To counter that perception, I’m pleased to share some new findings that underscore the importance of publicly supported basic research. In an analysis of more than 28 million papers in the PubMed.gov database, researchers found NIH contributed to published research that was associated with every single one of the 210 new drugs approved by the Food and Drug Administration from 2010 through 2016 [1]. More than 90 percent of that contributory research was basic—that is, related to the discovery of fundamental biological mechanisms, rather than actual development of the drugs themselves.

Faith Fortenberry

More than a decade ago, the NIH’s National Institute of Neurological Disorders and Stroke (NINDS) launched a special project to accelerate the translation of basic scientific discoveries into new treatments for a rare and often fatal disease. Five-year-old Faith Fortenberry whom you see above is among the kids who may benefit from the success of this pioneering endeavor.

Faith was born with spinal muscular atrophy (SMA), a hereditary neurodegenerative disease that can affect movement, breathing, and swallowing. When the NIH project began, there was no treatment for SMA, but researchers had discovered that mutations in the SMN1 gene were responsible for the disorder. Such mutations cause a deficiency of SMN protein, leading to degeneration of neurons in the brain and spinal cord, and progressive muscle weakness throughout the body. The NIH effort supported research to discover ways of raising SMN levels in cells grown in lab dishes, and then worked closely with patient advocates and pharmaceutical companies to move the most promising leads into drug development and clinical testing.

Given the desperate need for SMA treatments and all of the scientific energy that’s been devoted to pursuing them, I’ve been following this field closely. So, I was very encouraged to learn recently about the promising results of human tests of not just one—but two—new treatments for SMA [1, 2]. (more…)

Blood sample for PT INR test, diagnosis for coagulation disease

Every year, thousands of older Americans require emergency treatment to stop bleeding caused by taking warfarin, a frequently prescribed blood-thinning pill. My own mother received this drug in her later years, and her doctors encountered significant challenges getting the dose right. The problem is too much warfarin causes potentially serious bleeding, while too little leaves those who need the drug vulnerable to developing life-threatening clots in their legs or heart. The difference between too little and too much is distressingly small. But what if before writing a prescription, doctors could test for known genetic markers to help them gauge the amount of warfarin that a person should take?

Such tests have been available to doctors and patients for a few years, but they have not been widely used. The recent results of a national clinical trial offer some of the most convincing evidence that it’s time for that to change. In this study of 1,650 older adults undergoing elective hip or knee surgery, patients whose genetic makeup was used to help determine their dose of warfarin were less likely to suffer adverse events, including major bleeding. This trial marks an encouraging success story for the emerging field of pharmacogenomics, the study of how the variations in our genes affect our responses to medicines.

Emily Whitehead

Tremendous progress continues to be made against the Emperor of All Maladies, cancer. One of the most exciting areas of progress involves immunotherapy, a treatment strategy that harnesses the natural ability of the body’s own immune cells to attack and kill tumor cells. A lot of extremely hard work has gone into this research, so I was thrilled to learn that the Food and Drug Administration (FDA) just announced today its first approval of a promising type of immunotherapy called CAR-T cell therapy for kids and young adults with B-cell acute lymphoblastic leukemia (ALL)—the most common childhood cancer in the U.S.

ALL is a cancer of white blood cells called lymphocytes. Its treatment with chemotherapy drugs, developed with NIH support, has transformed ALL’s prognosis in kids from often fatal to largely treatable: about 90 percent of young patients now recover. But for those for whom the treatment fails, the prognosis is grim.

In the spring of 2012, Emily Whitehead of Philipsburg, PA was one such patient. The little girl was deathly ill, and her parents were worried they’d run out of options. That’s when doctors at Children’s Hospital of Philadelphia gave Emily and her parents new hope. Carl June and his team had successfully treated three adults with their version of CAR-T cell therapy, which is grounded in initial basic research supported by NIH [1,2]. Moving forward with additional clinical tests, they treated Emily—their first pediatric patient—that April. For a while, it was touch and go, and Emily almost died. But by May 2012, her cancer was in remission. Today, five years later, 12-year-old Emily remains cancer free and is thriving. And I’ve had the great privilege of getting to know Emily and her parents over the last few years.

Discussing clinical trials

Thinkstock

Today we took a huge step forward in our efforts to make sure that data from biomedical research is shared widely and rapidly. The NIH, in collaboration with our fine colleagues at the U.S. Food and Drug Administration (FDA), and with the valuable input from scientists, patients and other members of the public, has announced the HHS regulation and NIH policy to ensure that information about clinical trials is widely shared. In this blog I want to talk about what this will mean for patients, providers, and researchers. I also want to reflect a bit on how the new regulation and policy fit into our overall efforts to improve clinical trials and data sharing.

Clinical trials are essential for the translation of research advances to new approaches to prevention and treatment. Volunteers who take part in clinical trials often do so with no assurance of personal benefit, but with the expectation that their involvement will add to the growing body of knowledge about health and disease, and thus may help others someday. For that to be realized, all trial results information needs to be publicly reported in a timely fashion—and yet we know that doesn’t always happen. Today’s announcements aim to change that. The HHS regulation issued today, called a “final rule”, describes requirements for registering certain clinical trials and submitting summary results information from these trials to ClinicalTrials.gov, a database managed by NIH’s National Library of Medicine (NLM).
