FDA 2015: A Look Back (and Ahead) – Part 3: Food, Tobacco, and Antimicrobial Resistance



FDA 2015: A Look Back (and Ahead) – Part 1: Medical Product Innovation

By: Stephen M. Ostroff, M.D.
As the year draws to a close, I want to reflect on FDA’s many accomplishments in these previous 12 months, the last nine of which it has been my pleasure to serve as Acting Commissioner. FDA has broad responsibilities – indeed, we are tasked with overseeing products that account for about 20 cents of the consumer dollar — so we work on a wide range of topics in any given year. In this and two additional blog posts over the coming days I’ll cover some of our key accomplishments in 2015. Each blog will examine a different area of FDA’s work. This first post will focus on medical product innovation – our role in making safe, effective and innovative products available to patients who need them.
Acting FDA Commissioner, Stephen Ostroff, M.D.Scientific advances and unprecedented innovation in the sectors we regulate make it an exciting time to work at and lead FDA. To protect and promote the public health our regulatory decision-making must be nimble and current, adapted to the forward march of science.
One measure of our success is revealed in a study released in September by FDA’s independent Science Board. Mission Possible: How FDA Can Move at the Speed of Sciencedocuments the Agency’s progress and transformation over the last eight years, dating from a time when FDA had been increasingly unable to meet its scientific responsibilities due to chronic underfunding, a loss of scientific expertise, and the need to implement new legislative mandates without the resources to do so. In stark contrast, today FDA’s regulatory science enterprise is much stronger, which better allows us to effectively fulfill our commitment to protect the public health. The report also provides recommendations for future investments in regulatory science to assure FDA keeps pace with emerging trends in science and technology.
Medical Product Approvals
For many years now, we’ve strived to modernize and streamline the regulatory process along the entire development, review, and product oversight continuum.
The success of these changes is shown by the large number and wide variety of medical products we’ve approved across our medical product centers. So far this year, we have approved more than 40 novel drugs, including four new treatments for patients with multiple myeloma, two new drugs for patients with heart failure, and another robust year of approvals of drugs for rare or “orphan” diseases. We’ve approved several important vaccines, including one for serogroup B meningococcal disease, the first seasonal influenza vaccine to contain an adjuvant (intended for people 65 years and older), and a new indication for anthrax vaccine to prevent disease following exposure to anthrax – the first vaccine to receive an approved indication based on the Animal Rule (which provides for testing certain products on animals alone). And we saw the approval of several innovative devices that will make a positive difference in the lives of patients, including a device that extends the survival time of patients with brain cancer, and a transcatheter pulmonary valve that can be placed in certain patients with congenital heart disease, without requiring open heart surgery.
Our success is also measured in our speed and efficiency of approvals. The U.S. continues to lead the world in approving novel drugs first. And we’ve seen important progress in our device review program. Our average time to reach decisions on PMAs has dropped 36 percent since 2009. And not since 2001 FDA has approved as many medical devices under the original premarket approval pathway and the panel track supplement pathway (for significant changes to a PMA device) as we did this year – 58 as of December 14th.
The number of approvals, and the agency’s ability to review products efficiently, continue to be buoyed by FDA’s expedited development and review programs. When we talk to drug and device makers at the early stages of development, and apply better regulatory science to our ultimate review of their applications, products that are likely to fail are weeded out, allowing manufacturers to focus on those more likely to attain approval.
Most importantly, enhanced flexibility and an efficient approval process have come without lowering our gold standard of safety and efficacy. At the end of the day, innovative therapies are only helpful to patients if they work and are demonstrated to be safe. So it is imperative that we ensure the right balances among patient access, sound science, and safe and effective products.
Amplifying the Patient Voice
Enhancing the patient’s voice in the medical product approval and evaluation process is an important emerging area of product development, which we have embraced in a number of ways.
Those living with a disease are in a unique position to provide essential insights about life with their condition, its severity, and the adequacy of treatment options. We also recognize patients and caregivers have their own perspectives on benefits and risks of medical products, and we believe this input should be considered during regulatory decision-making.
Our Patient-Focused Drug Development initiative is a five-year effort that includes holding at least 20 public meetings in different disease areas. Seventeen of those meetings have occurred and seven more are being scheduled. After receiving patient input during each meeting and in the agency docket, FDA develops a Voice of the Patient report that is then posted on our website. In a complementary effort, our medical device program launched the Patient Preference Initiative. It includes studies to evaluate patient preferences in medical devices, and publishing of a draft guidance that describes how patient tolerance for risk and perspective on benefit, in addition to clinical data and other information, may be considered in FDA’s benefit-risk assessments for certain medical devices. This year FDA approved a weight loss device treatment, and our decision was informed in part by data from a patient preference study funded and co-designed by the Agency.
In September 2015, FDA announced our first-ever Patient Engagement Advisory Committee, which will provide advice on complex issues related to the regulation of medical devices and their use by patients. This Advisory Committee will help ensure the needs, experiences, and perspectives of patients are considered in our work and incorporated in our decision-making.
Biosimilars
Five years ago Congress authorized an abbreviated licensure pathway for biological products that are demonstrated to be “biosimilar” to or “interchangeable” with an FDA-licensed biological product. The intent was to create greater competition in the medical marketplace that would not only increase treatment options for patients, but also lead to less expensive alternatives to comparable products. FDA has been developing its biosimilar program since then, an effort which led to the approval of the first biosimilar in March. And there are more applications in the pipeline. To prepare, FDA has produced a variety of guidances in this area, including the recent draft guidance on how these biosimilars should be named.
Advancing the Development of Next Generation Sequencing Tests and Strengthening Clinical Trials
Our strengthened focus on regulatory science is helping to drive innovation. One illuminating example is our growing ability to apply the sophisticated technologies of next generation sequencing and precision medicine.
FDA today is better prepared and more engaged than ever in facilitating the development of these new technologies (as well as new uses for older technologies), while assuring they are safe and effective. These efforts help to achieve more precise diagnosis or treatment, through the development and review of state of the art diagnostics that use genetic information to make therapies more targeted.
We continue to move forward on the White House’s Precision Medicine Initiative to advance biomedical understanding by leveraging genomic advances, health information technologies, and new methods of analyzing large volumes of data. Just this month, we launched FDA’s precisionFDA web platform, a cloud-based portal that will allow scientists from industry, academia, government and other partners to come together to foster innovation and develop the science behind next-generation sequencing and help us design treatments tailored to a person’s individual genetic blueprint.
And we also are working to refine clinical trial design and statistical methods of analysis to create more efficient studies with smaller patient populations, more focused therapies, and better outcomes. For instance, we continue to support collaborative efforts in clinical trials, such as the I-SPY trials (for breast cancer) and the Lung-MAP protocol (for lung cancer).
It’s impossible to capture in one blog post the many ways that FDA’s focus on regulatory science is helping drive innovation and speed the discovery, development, and delivery of medical products to prevent and cure disease and improve health. We are immeasurably proud of these accomplishments, which provide a strong foundation for continuing success.

FDA 2015: A Look Back (and Ahead) – Part 2: Medical Product Safety and Oversight

By: Stephen M. Ostroff, M.D.
In my first look back on FDA’s 2015 accomplishments, I focused on our achievements inmedical product innovation and our constant drive to make safe, effective and innovative products available. Because FDA’s responsibility covers the entire life cycle of products, in this second year-end blog post, I will review FDA’s impact on medical product safety and oversight.
Acting FDA Commissioner, Stephen Ostroff, M.D.Responding to Ebola
In a world where disease knows no borders FDA’sresponse to the Ebola epidemic in West Africa demonstrates how we use our scientific expertise and regulatory authorities to the fullest extent possible to address a tragic public health crisis of global impact. Our response involved collaborating with partners across government, pharmaceutical and diagnostic companies, international organizations like the World Health Organization, and our international regulatory counterparts. We played a key role in expediting the availability of diagnostic tests and investigational therapeutics and vaccines, as well as investigating fraudulent products marketed to diagnose, prevent and treat Ebola. And many FDA commissioned corps officers of the U.S. Public Health Service served on the front lines, deployed in a humanitarian mission to provide care to patients at the Monrovia Medical Unit in Liberia, one of the West African nations that were hard hit by the outbreak.
Addressing Transmission of Infections from Duodenoscopes
This year we took steps to help protect the public from the risk of transmitted infections, including antibiotic-resistant infections, from duodenoscopes. Duodenoscopes are complex devices used during endoscopic retrograde cholangiopancreatography (ERCP), a potentially life-saving procedure to diagnose and treat blockages in the pancreas and bile ducts. In the United States, duodenoscopes are used in more than 500,000 ERCP procedures each year.
Last February, the FDA issued a safety communication to raise awareness about the risk of transmitted infections from duodenoscopes, after it determined that the design of these devices may impede effective reprocessing, even when the manufacturer’s reprocessing instructions are followed correctly. Reports also indicated that some healthcare facilities may not have adequately followed the manufacturer’s reprocessing instructions. To address these concerns, the FDA has been working with the device manufacturers to ensure that the reprocessing instructions for their duodenoscopes are put through the most rigorous testing. The Agency held a public advisory committee meeting in May to discuss the scientific challenges, and it incorporated recommendations for enhancing the safety margin of reprocessing duodenoscopes into a safety communication in August. Also in August, FDA issued Warning Letters to all three duodenoscope manufacturers citing violations found during recent inspections. In October, the FDA ordered the manufacturers to develop postmarket surveillance studies of how the devices are reprocessed in real-world clinical settings.
Our foremost concern is protecting patients, and we are committed to taking steps to assure that duodenoscopes – and all reprocessed medical devices — are safe to use.
Compounding
We continue to respond effectively to the 2012 outbreak of fungal meningitis linked to contaminated compounded drugs. We are implementing the Drug Quality and Security Act and continuing our inspection and enforcement efforts at compounding facilities nationwide. To that end we have issued numerous policy documents regarding compounding and related activities to provide guidance to industry as we implement the new law. We’ve also held meetings with stakeholders, including pharmacy, physician, and consumer groups, and we have continued our active and successful collaborations with state governments.
Addressing the Opioid Abuse Crisis
Over the last year, we’ve been very focused on the growing epidemic of opioid abuse and addiction and its devastating impact on public health. This focus has required us to strike a delicate balance: ensuring medical treatments are available for patients who are in pain, while addressing the often tragic consequences of abuse and misuse, which all too often overwhelm individuals, families, friends and communities. Our approach is multi-pronged, from encouraging scientific investigation to improving the training of practitioners who prescribe these powerful medicines.
We believe it is vitally important to encourage the development of abuse-deterrent formulations of opioids and to support options for medication-assisted treatment of opioid-dependence. Final guidance for industry regarding the development of abuse-deterrent formulations was issued in April and several abuse-deterrent products have been approved. We are also making strides to treat the consequences of overdoses. In November, FDA approved the first nasal spray version of naloxone hydrochloride, to provide a route of delivery in addition to injection for this life-saving medication that can stop or reverse an opioid overdose. And we are working with our federal partners to improve access to naloxone.
While we cannot solve this complex problem alone, we remain committed to making the best use of our regulatory authorities and working with our partners both in and outside government to reduce the risks associated with opioids. To continue to achieve that, we have been engaging in a comprehensive review of our many current activities related to opioids and identifying which measures can and should be strengthened and what further measures are needed to address this crisis during 2016.
Ensuring the safety of the medical products we regulate requires us to manage a wide-range of issues across multiple scientific disciplines; and to employ scientists with the knowledge to solve today’s complex regulatory challenges. The last year brought many challenges, and just as many solutions.
In my final post, I will address some of our accomplishments in the area of food, tobacco product regulation, and antimicrobial resistance.

FDA 2015: A Look Back (and Ahead) – Part 3: Food, Tobacco, and Antimicrobial Resistance

By: Stephen M. Ostroff, M.D.
In my third and final post reflecting on FDA’s work to protect and promote public health in 2015, we’ll take a look at our achievements in food, antimicrobial resistance, and tobacco product regulation.
Acting FDA Commissioner, Stephen Ostroff, M.D.Modernizing Food Safety
In a groundbreaking development, in 2015 FDA took several major steps to prevent foodborne illness by finalizing five rules that will implement the landmark FDA Food Safety Modernization Act (FSMA).
In September, we issued the first two final FSMA rules mandating modern, preventive practices in both human and animal food facilities. They will help establish a food safety system in which industry systematically implements measures we know are effective in preventing contamination.
In November, we took another step toward modernizing our food-safety system by issuing the final produce safety rule and two import safety rules. For the first time, these new rules establish enforceable science-based safety standards for the growing and harvesting of produce and make importers accountable for conducting risk-based verification to determine that imported food meets U.S. safety standards. In addition, through this rulemaking we established a program for the accreditation of third-party certification bodies to conduct food safety audits of foreign food facilities.
Together, these rules are designed to reduce the burden of foodborne illness in the United States. They support the broad goal of the law to proactively prevent problems across the entire food system, and to strengthen food safety coordination with other nations that produce the foods that Americans consume.
Strengthening Nutrition, Protecting Health
2015 also saw important progress in the area of nutrition. We finalized our determination that partially hydrogenated oils, the primary dietary source of artificial trans fat in processed foods, are not generally recognized as safe (GRAS) for use in human food, a decision that will make an enormously positive difference in the health of Americans. We also are continuing to work to develop sodium reduction targets, which have the potential for major public health gains and cost savings to the health care system.
And late in 2014, we finalized two new rules requiring caloric information on restaurant menus and menu boards and on vending machines. These rules are designed to provide consumers with more information so they can make informed choices for themselves and their families, without placing an undue burden on small businesses or individual food establishments. We are working with industry to support implementation.
We also proposed additional changes to the familiar “Nutrition Facts” label on packaged foods which, when finalized, will give Americans updated nutrition information, reflecting the most current nutrition science, to help them make healthy choices when purchasing packaged foods. This includes a revision that would establish a Daily Reference Value for added sugars and require the percent Daily Value on the label. There is strong evidence healthy dietary patterns of intake associated with a decreased risk of cardiovascular disease are characterized, in part, by lower intakes of sugar-sweetened foods and beverages.
Combating Antibiotic Resistance
Another area in which we saw great progress in 2015, thanks to collaborative efforts across our government and with our international partners, was in combating antibiotic resistance. If left unchecked, this growing problem threatens to turn back the clock on decades of progress in infectious disease control and medical discoveries, drive health care costs higher, and increase human disease and death.
Early in 2015, the White House released the National Action Plan for Combating Antibiotic-resistant Bacteria, a plan that that recognizes that humans and animals share the same environment – and the same microbes – and so we must address the use of antibiotics in both.
One of the central principles for slowing the development of resistance – in both humans and animals – is the judicious use of antibiotics. For decades medically-important antibiotics have been used not only to treat sick animals, but to promote growth in healthy ones. The FDA has already made significant progress developing policies to promote appropriate use of antibiotics in animal health. For instance, we issued the Veterinary Feed Directive (VFD) final rule, an important part of our overall strategy because it promotes judicious use of medically important antimicrobials in feed for food-producing animals by bringing the use of these drugs under veterinary supervision.
But a critical part of combating resistance is to know the changing patterns and use of antibiotics in farming and how these changes impact resistance patterns among foodborne pathogens associated with farm animals. We are strengthening our data collection under the National Antimicrobial Resistance Monitoring Program in several ways, and in September we held a Public Meeting with several other federal agencies on data collection on farms. This and other work will help us to develop a more comprehensive and science-based understanding of antimicrobial drug use and resistance in animal agriculture and help us to measure the impact of our regulatory actions.
While the problem of antimicrobial resistance is finally getting the attention it warrants, it will require an ongoing and sustained effort to overcome the decades of neglect that led to the current situation.
Regulating Tobacco Products
Our newest area of regulatory oversight is one of our busiest. It’s hard to believe it was more than 50 years ago that the Surgeon General issued the first Report on Smoking and Health. But it’s been just six years since Congress passed the Tobacco Control Act, which gave FDA the authority to oversee the manufacture, marketing, distribution, and sale of regulated tobacco products and protect the public from their dangers.
We’ve already built a great deal on that foundation, creating our Center for Tobacco Products and establishing a framework for industry registration, product listing and submission of information on ingredients in tobacco products; implementing and enforcing a statutory ban on cigarettes with certain characterizing flavors; and restricting access and marketing of cigarettes and smokeless tobacco products to youth. We’ve also already begun to build a robust regulatory science program to conduct and fund science and research programs designed to help us better understand the risks associated with tobacco use.
After an extraordinary amount of study and research, and review of tens of thousands of public comments, FDA is preparing to publish the final rule to extend the agency’s authority over additional, unregulated tobacco products, such as e-cigarettes, cigars, hookah tobacco, and pipe tobacco. Like everything we do at FDA, this policy will be based on a thorough scientific evaluation of how individual products in each category may affect public health.
And in 2015, we unveiled a dynamic public education campaign designed to prevent and reduce tobacco use among at-risk African Americans, Hispanics, and Asian American/Pacific Islander youth age 12 to 17. This promising effort flows from our “Real Cost” campaign launched in 2014, which I’m pleased to note, won a gold “Effie Award” for effectiveness in advertising in the Disease Awareness and Education category.
It’s been a fruitful and productive year at the FDA. I am proud of all we have accomplished in 2015 and look forward to our continued progress.
