This bill promises to speed up drug approvals so much that it’s making people uncomfortable

By Carolyn Johnson, The Washington Post
July 8, 2015

The bill slated to land on the House floor on Thursday seems unassailable on its face – the 21st Century Cures legislation promises to modernize medicine and speed the development of lifesaving treatments.

But a vocal chorus of physicians and pharmaceutical industry watchdogs warn that the bill is full of stealth provisions that could actually put sick people in harm’s way, by speeding the development of treatments that are neither safe nor effective.

It’s not exactly easy to oppose a widely-supported bipartisan bill that is often referred to as just “Cures.” But opponents say the proposed law is full of flaws, starting with its name and its key premise: that bottlenecks in the regulatory process are a big reason we haven’t cured cancer, Alzheimer’s, and a panoply of rare diseases.

To drug companies and patient advocates, expedited access to drugs and devices might seem like a huge boon. But critics are worried that the law will relax America’s standards for evaluating new drugs and devices, which are approved based on careful review of evidence — including rigorously designed clinical trials. The bill offers up a slew of new ways to evaluate drugs: for example, allowing antibiotics to be approved based on what would today be considered preliminary evidence — animal and test tube studies and very small trials in people. New medical devices could be approved based on “case histories” — potentially of just a handful of patients.

“The irony is calling this 21st Century Cures, when they’re talking about standards that were left behind in the 20th century, because they were found to not be good,” said Diana Zuckerman, president of the National Center for Health Research, a nonprofit, non-partisan think tank that does not accept money from drug or medical device companies.

Here are a few of the provisions that have sparked debate:

-The bill would allow antibiotics to be approved based on laboratory and animal tests and small, early clinical trials.

-The bill allows companies to seek expedited drug approval based on so-called “surrogate endpoints” — early indicators that a drug is working, such as whether a tumor has stopped growing in cancer.

A study published last month in the journal JAMA Internal Medicine found that efforts to expedite cancer drug approval by using such criteria has resulted in the approval of many cancer drugs that do not extend life, but do have side effects.

-The bill also threatens disclosure requirements that are intended to limit pharmaceutical companies’ influence on physicians. The bill would allow physicians to receive speaking fees and gifts from companies without disclosing them, as long as they were for medical education.

Hope for children’s rare drug approval process

By Lisa Gillespie, USA Today (Kaiser Health News)
June 7, 2015

Advocates for children with rare diseases are watching closely a congressional effort to streamline the nation’s drug approval process because the bill includes a provision that would extend a federal program that rewards companies making remedies for these young patients.

The reward program, the advocates say, offers hope to families that often have very few options. Approximately 15 million children are diagnosed with rare diseases, and 35% of deaths in the first year of life are caused by them.

“Treatments aren’t getting to kids, and kids deserve more than the leftovers,” said Nancy Goodman, the founder and executive director of the advocacy group Kids v Cancer. Goodman’s 10-year-old son died from brain cancer. She helped push for the original reward program in the hope that children like her son would have access to a wider range of treatments.

The extension of that program is part of the bipartisan 21st Century Cures bill, which seeks to rewrite the rules for drug development to make innovative treatments available faster. The overall bill has generated support on Capitol Hill, but some critics contend that it has the potential to undermine drug safety and to profit drugmakers.

Children’s advocates say there is a shortage of good therapies for rare and often deadly pediatric diseases that can include a wide variety of conditions including cancer, skull deformities or enzyme deficiencies. Pharmaceutical companies have historically been hesitant to test drugs for children because of concerns about potential negative outcomes, children’s ability to consent to treatment and the perception that the market for these drugs was limited. So doctors have often been left to try adult-tested drugs on sick children but without the studies that show pediatric safety or effectiveness. But drugs used on adults don’t always work on children in the same way because of differences in metabolism and maturation of organs.

The advocates say more research needs to be conducted with children. But that testing is a sensitive process. It can be very costly and it requires extra care because there are more stringent ethical protocols to protect these minors, who can’t often give informed consent. Bad results — either injuries or deaths — can set back research efforts and have financial consequences for the company.

With that in mind, Congress in 2011 set up a program to help promote more pediatric drug research. It gives creators of medicine for rare pediatric diseases a voucher that they can use to have another one of their drugs approved quicker than usual — six months vs. a process that can run a year or often more.

Drugmakers can also sell that voucher, which can be a big windfall for a small drug company trying to recoup research and development costs. There have been four vouchers given out since 2014, and one was sold for $67.5 million and a second for $125 million.

The voucher program, which advocates say holds big potential, expires next year. The cures bill seeks to extend it another three years.

“A lot of companies are reluctant to get into pediatric drug development because it’s very difficult if something goes really wrong,” said Alexander Gaffney of the Regulatory Affairs Professionals Society, an association for people involved in overseeing health care or the quality of health care products.

Drugs that are approved for cancer in adults are commonly not approved in kids. “Children are not simply small adults, they metabolize drugs very differently,” Gaffney said.

Critics say that however well-intentioned the voucher program is, it could have some unintended consequences. For example, a company could get a drug approved by theFood and Drug Administration but never bring it to market, if the maker decides it would not generate enough money. Yet the company would still pocket the priority review voucher.

Because of the speed sought by the program, vouchers could be given out without some of the safeguards that come in more traditional testing. For example, the research might not uncover that the drug could be fatal to a child after a few months or years.

Diana Zuckerman, president of the National Center for Health Research, a non-profit group that seeks to represent children and families on health research policy issues, says the rush in moving drugs through the system can obscure problems. Drugmakers “shouldn’t be able to sell it [or use it] unless it works,” she said.

She noted that in some studies as few as 10 kids are included because the disease is so rare. With such a small population size, the company is not likely looking at big profits.

“When you’re doing a study of rare disease, it’s a small sample size and it’s easy to manipulate the data to make it look better than it is,” said. “You don’t want an incentive to represent the company wrongly in the short term,” to get the voucher for another larger drug.

Julia Jenkins, executive director of the EveryLife Foundation for Rare Diseases, an advocacy group pushing for drug companies to spend more on drug development, wants the pediatric drug voucher program extended. She notes that the program is still too new for officials to evaluate whether it is effective.

One problematic part of the current House version, she said, is that it only extends the program for three years, and drug companies generally need 10 years to scratch up investors and research a new drug. The potential reward of expedited drug review might not be enough to allow a company to make a financial plan for a drug based on the program.

The expanded bill covers more than 60 health issues, including a $10 billion boost in funding for the National Institutes of Health and $550 million in extra money for the FDA over the next five years. Other provisions include creating a database of genomic information from a million U.S. patient volunteers and allowing the FDA to approve drugs without the gold-standard clinical trial, instead using smaller observational studies or clinical experiences.

The bill passed the House Energy and Commerce Committee unanimously in May and is expected to come up for a vote in the full House. Senators are in the early stages of working on a similar bill.

Speeding up drug-approval process could have downside

By Ed Silverman

Excerpted from The Wall Street Journal, May 30, 2015.

Would a congressional bill designed to jump-start medical innovation end up lowering standards for approving new uses of existing medicines?

Consumer advocates are raising this concern about the 21st Century Cures legislation, which passed the House Energy and Commerce Committee unanimously last week and, in part, is designed to reform the approval process for drugs. Supporters say the bill is a long overdue move that, among other things, will give the FDA the tools to ensure treatments reach patients faster.

But critics say that a section of the bill devoted to drug development is problematic. Specifically, they point to language that would allow the FDA to approve additional uses for drugs without having to rely on randomized controlled trials. These are considered to be the gold standard for determining whether a medicine offers a benefit, and they help gauge the extent to which there are risky side effects.

The bill, however, pushes aside evidence in favor of something called “clinical experience,” which is defined as a mix of observational studies, patient registries and therapeutic use. None of these, however, are viewed as scientifically rigorous for establishing whether a drug may be effective. Instead, critics say the language in the bill is sufficiently, perhaps deliberately, vague.

“Clinical experience is something that should be considered as additional information, but absolutely never take the place of scientific data,” says Diana Zuckerman, who heads the National Center for Health Research, a nonprofit think tank. “By urging FDA to get away from randomized clinical trials, drug makers may have more power to urge the FDA to consider data that is favorable to their product.”

Bill to speed approvals for drugs is cut back

By Sabrina Tavernise,  New York Times
April 30, 2015

WASHINGTON — Legislation that would have accelerated the pace of federal drug approvals in a way that critics said threatened to erode patient safety was formally released this week, in a scaled-back version with many of the most controversial provisions left out.

The  draft bill  presented at a  hearing  in the House on Thursday represents a less aggressive streamlining of the drug approval process, critics of the earlier draft said, and seems to have secured strong bipartisan support.

The legislation, called 21st Century Cures, has been in the works for months. Its lead sponsor, Fred Upton, Republican of Michigan, said it would speed the pace of drug cures by removing unnecessary hurdles from the regulatory process.

Critics, including top officials at the  Food and Drug Administration,    had expressed concern that the changes would risk patient safety — for example, by potentially permitting shorter clinical trials and letting drug companies use alternative measures of health as evidence of a drug’s effectiveness and safety.

The bill’s supporters said it was a work in progress that had been assembled in one of the most collaborative, transparent processes Congress has seen in years. The sponsors held eight hearings and more than a dozen round-table meetings in districts across the country to gather comment.

“We have a chance to do something big, and this is our time,” Mr. Upton said.

His co-sponsor, Diana DeGette, Democrat of Colorado, said the lawmakers had made “tremendous progress,” recalling “that hokey video” that she and Mr. Upton made to promote the effort last year.

The draft — at about 200 pages it is half its former size — seemed to allay fears among some experts that it would fundamentally rewire the way drugs are approved. Earlier proposals to give drug companies broad powers to promote their products for uses other than the approved ones and to market brand-name drugs for a longer time without generic competition were not included.

The F.D.A. has defended its record for drug approval speed, saying that in 2014, it approved the most new drugs in almost 20 years, and that it moves faster than its counterparts in other wealthy countries. Experts note that pathways exist for expedited approval, and that the F.D.A. is held to relatively strict timelines under other rules set by Congress. Instead, they say, the bottleneck for new drugs is often a matter of the years of research it takes to find them.

Diana Zuckerman, the president of the National Center for Health Research, said earlier versions of the legislation had “considerable micromanaging of the F.D.A. and enormous power given to industry.”

She added, “Most of that is gone.”

But she cautioned that the bill still held numerous provisions she believed put people at risk, including ones she described as lowering standards for the approval of medical devices and antibiotics. The bill would increase the work the F.D.A. must perform, but not the money it receives, and Dr. Janet Woodcock, an agency official who testified Thursday, said that was a concern.

“We are very stretched in our resources,” she said.

One point that is likely to concern the F.D.A. is a provision that would reduce its authority to regulate some software associated with medical devices.

An earlier version of the bill would have let drugmakers use quicker measures for a drug’s effectiveness during testing — for example, changes in blood sugar level instead of a more final outcome, like development of  diabetes. The new draft instead suggests ways the F.D.A. could use those alternative measures, called biomarkers.

The F.D.A. says it already uses them in a substantial share of drug approvals, and Dr. Woodcock told the lawmakers Thursday that the agency did not need additional authority on this count. Progress has been slow in adopting more biomarkers, she said, because they often did not produce enough evidence to allow scientists to draw firm conclusions.

“You have to know those biomarkers are reliable before you can take a chance on a human life,” she said.

What do stakeholders think of FDA’s latest effort to get patients timelier access to devices?

By Michael Williamson, Bloomberg BNA

The FDA April 8 released two final guidance documents that will help provide timely patient access to high-quality, safe and effective medical devices for unmet medical needs, Jeffrey Shuren, the director of the agency’s Center for Devices and Radiological Health, said in a blog posting.

Reaction to the two documents is mixed – pitting industry against some patient advocates.

One guidance document describes the FDA’s Expedited Access Program (EAP), which should “speed qualifying devices to patients with life-threatening or irreversibly debilitating conditions” without compromising the agency’s high standards for safety and effectiveness, Shuren’s blog posting said. The other guidance document outlines the agency’s current policy on balancing premarket and postmarket data collection during FDA review of premarket approval (PMA) applications. In addition, the document addresses whether or not the circumstances when postmarket data collection is appropriate for PMAs meet the criteria for the EAP.

Two stakeholders seemed pleased with the EAP document. The Advanced Medical Technology Association (AdvaMed), “commends the agency for its efforts to explore supplementary review pathways to provide more timely patient access to new technologies for life-threatening or irreversibly debilitating diseases or conditions that addresses an unmet medical need,” Janet Trunzo, the association’s senior executive vice president for technology and regulatory affairs, told me in a April 9 e-mail.

In addition, Ben Moscovitch, officer with the medical device project of the Pew Charitable Trusts, a nonproft policy organization, told me April 9 many of the recommendations his group made on the draft version of the EAP document were included in the final document. For example, he told me that the EAP final guidance document reflects a Pew suggestion from 2014 that the FDA should require the initiation of postmarket trials and completion of those studies within a certain timeframe.

Not everyone is pleased with the guidance, however. The EAP final guidance “is part of a larger problem where the FDA is bowing to pressure from Congress to weaken safeguards that are intended to protect patients from unsafe medical products,” Diana Zuckerman, president of the National Center for Health Research, told me in an April 9 e-mail. She is also president of the Cancer Prevention and Treatment Fund.

Medicare panel voices doubts about genetic cancer tests

By Virgil Dickson, Modern Healthcare

The Medicare Evidence Development and Coverage Advisory Committee (MEDCAC) has expressed little confidence in genetic tests that supposedly predict common cancers. The decision raises doubts about whether the CMS will authorize Medicare coverage for such tests.

“This is such a promising and exciting field, but the excitement is far ahead of the data,” said Diana Zuckerman, a panel member and president of the National Center for Health Research, an advocacy organization. These tests “could be so helpful if only we knew more.”

Specifically, there was a concern among committee members who met Tuesday about the lack of data regarding clinical utility, which indicates if a test result was actually helpful to a consumer.

“The evidence got very thin, very quickly,” said Dr. Beverly Guadagnolo, a panelist and associate professor in the radiation oncology department at the University of Texas.

Industry stakeholders present at the meeting disagreed. “Two hundred-plus labs around the country wouldn’t be doing these tests if they didn’t have clinical utility,” Dr. Jan Nowak, medical director of molecular diagnostics and cytogenetics at NorthShore University HealthSystem, Evanston, Ill., said during public comments.

Another leading concern was to ensure people did not undergo unnecessary chemotherapy. “We need to be on the side of the angels and minimize access to drugs that don’t necessarily need to be given,” said Dr. Josef Fischer, a panelist and professor in the surgery department at Harvard Medical School and Beth Israel Deaconess Medical Center.

The eight-member panel was asked to vote on a scale of 1 to 5 on how confident members were that the tests they were reviewing would actually benefit Medicare beneficiaries by bettering quality of life, helping them avoid inappropriate anti-cancer treatments or death. The tests that were up for consideration claim they help predict the chances of colon, rectum, breast and lung cancers.

Panel member votes were collected and averaged. Most of the tests received an average score under 3, though a test related to breast cancer rated higher at 3.8. Another test meant to find cancerous lung cancer genes scored the lowest at 1.375.

The panelists also were asked to discuss if they would feel more comfortable with a test being used by beneficiaries if it were a laboratory-developed test from a facility certified under the Clinical Laboratory Improvement Amendments or a test that received Food and Drug Administration approval or clearance. Members seemed more comfortable with an FDA-approved test.

It’s unclear what direction the CMS will take moving forward. MEDCAC is generally considered influential, but the agency recently decided to not concur with a committee vote to not recommend Medicare coverage of annual CT scans to detect lung cancer in heavy smokers.

During the meeting, CMS liaison Dr. James Rollins indicated that any future coverage given to these type of tests would need to prove clinical utility. Today, most entities developing these tests focus on proving analytical validity, how accurately a test detects a specific genetic variant, or clinical validity, how well the genetic variant is being analyzed.

Breast implants in France to carry cancer warning: researchers find a ‘clearly established link’

By Dana Dovey, Medical Daily
March 18, 2015

Following France’s National Cancer Institute finding a “clearly established link” between breast implants and a specific type of cancer, the country will now order all breast implants to come with a cancer warning. This announcement came after 18 cases of anaplastic large cell lymphoma were directly linked to women with silicone breast implants since 2011.

Anaplastic large cell lymphoma (ALCL) is a type of non-Hodgkin’s lymphoma that affects the blood. The link between breast implants and this form of cancer is extremely rare, so French officials have urged women who already have the implants not to remove them, the Daily Mail reported. Given the severity of the cancer in the few women who do develop it, French officials felt it necessary to inform women of all the possible risks associated with the surgery.

ALCL is extremely rare, affecting around one to six in every three million women who undergo breast augmentation, Medical News Today reported. However, a study conducted by researchers from Cambridge University in the UK found that nearly all cases of ALCL in breasts occurred in patients who had undergone breast augmentation, suggesting a link between the two. Although it’s not clear why silicone breast implants can sometimes cause cancer, the Cambridge investigation did shed some light on the mystery.

“It’s becoming clear that implant-related ALCL is a distinct clinical entity in itself,” Dr. Suzanne Turner, lead researcher of the Cambridge study, told Medical News Today. “There are still unanswered questions and only by getting to the bottom of this very rare disease will we be able to find alternative ways to treat it.”

Breast implants are a very popular surgery, with Dr. Diana Zukerman, president of the National Center for Health Research, explaining that in 2013 alone 300,000 American women opted for the operation. Of these women, around 80 percent undergo breast enhancement for cosmetic reasons while a further 20 percent have breast implants following breast cancer.

This is far from the first time that breast implants have been implicated in causing a health hazard. In 2011, French firm PIP caused global hysteria when plastic surgeons reported an abnormal amount of the implants rupture, the Daily Mail reported. It was later found that the firm had been manufacturing these breast implants using industrial grade silicone intended for use in mattresses.

The implants were subsequently found faulty and banned from use. Women who had already received the implants were advised to have them removed, although European health officials found no medical or toxicological evidence to back this advice.

Candidate to lead FDA has close ties to big pharma

By Massimo Calabresi, Time

Duke’s Dr. Robert Califf sees closer collaboration between government and industry

Dr. Robert CaliffLast May, Duke University’s Vice Chancellor for clinical research, Dr. Robert Califf, told an audience of executives that the American system for developing drugs and medical devices was in crisis. Using slides [pdf] developed by Duke’s business school, he said the system was too slow and too expensive, and required disruption and transformation. Towards the end of his talk, he put up a slide that identified a key barrier to change: regulation.

Such views are not uncommon in industry, academic research and on Capitol Hill, but they are noteworthy coming from Califf because he could soon be America’s top regulator overseeing the safety and efficacy of the country’s drugs and medical devices. Califf is already set to become deputy commissioner at the Food and Drug Administration (FDA) next month. Now sources familiar with the process tell TIME he is on President Barack Obama’s short list to run the agency following this month’s announcement that its long-serving commissioner, Margaret Hamburg, will step down in March.

The White House declined to comment on pending personnel decisions, but word that Califf is in contention for the top spot at the FDA comes at a key moment. The agency faces potentially dramatic changes this year as Congress prepares to rewrite many of the rules for how drugs and medical devices are reviewed and tested for safety and efficacy. Califf is widely respected in the public and private sectors, but his candidacy is seen by some as a threat to the independence and authority of the FDA, thanks to his views on the need to accelerate change and his deep financial and intellectual ties to the pharmaceutical and medical device industries.

Califf says his salary is contractually underwritten in part by several large pharmaceutical companies, including Merck, Bristol-Myers Squibb, Eli Lilly and Novartis. He also receives as much as $100,000 a year in consulting fees from some of those companies, and from others, according to his 2014 conflict of interest disclosure [pdf]. In an interview with TIME, Califf estimates that less than half of his annual income comes from research money provided by the pharmaceutical industry, though he says he is not certain because he doesn’t tend to distinguish between industry and government research funding. He says he is divesting his holdings in two privately-held pharmaceutical companies he helped get off the ground.

Califf says such collaboration, not just between industry and academia, but with government, too, is the way of the future. “The greatest progress almost certainly will be made by breaking out of insular knowledge bases and collaborating across the different sectors,” Califf says. He says there is “a tension which cannot be avoided between regulating an industry and creating the conditions where the industry can thrive, and the FDA’s got to do both.” He says it would be “useful to have someone [leading the FDA] who understands how companies operate because you’re interacting with them all the time.”

Diana Zuckerman, President of the National Center for Health Research, which advocates for FDA regulatory authority, says such ties “should be of great concern.” Dr. Califf is “a very accomplished, smart physician who’s been an important name in the field,” Zuckerman says, but his “interdependent relationships” raise questions about his “objectivity and distance.” She cites several studiessuggesting the medical products industry uses such ties to influence the behavior and decision making of doctors and researchers, even when the scientists don’t realize it.

The tension over Califf’s collaboration with industry gets to the heart of the future of the FDA at a pivotal moment. While FDA defenders see the collaboration as a threat to its independence, others see close relationships between government, industry and academia as the model for the future. Califf heads a successful and powerful clinical research program, the Duke Translational Medicine Institute, which brings together industry drug researchers, academic scientists and federal regulators to speed drug development and approval. Califf estimates 50-60% of its $320 million in annual research funding comes from industry.

Capitol Hill is considering codifying parts of that collaborative model for the FDA. The powerful Energy and Commerce Committee in the U.S. House of Representatives recently introduced a draft bill called 21stCentury Cures, which would loosen the drug approval and post-market oversight process. Califf says because the bill is still in draft it is too early to pass an overall judgment on it but he says, “I support a lot of the concepts in the bill.”

In the Senate, the Health, Education, Labor and Pensions (HELP) committee has begun work on its own bill, with committee chairman Lamar Alexander declaring, “It takes too long and costs too much to develop medical products.” In a report paving the way for his legislation, Alexander concluded the FDA has grown too large, has fallen behind scientific innovation and threatens American leadership in biomedical innovation. Reform efforts in the Senate may be aided by the support of liberals like Elizabeth Warren who back looser regulations on the medical device industry.

The FDA uses a model for drug testing and oversight largely developed in the early 1960s, with phased trials before drugs and devices are approved for sale to ensure they are safe and effective, and “post-market” studies afterwards to monitor them. Over time, the agency has come to rely on the medical product industry for more than 60% of its budget for post-market monitoring.Accused of regulatory capture by those who see undue industry influence, the FDA has faced attacks from both sides.

That means the FDA has few defenders and will rely heavily on its next commissioner to stand up for it in public and on Capitol Hill. “This is a very dangerous time for the agency,” says Zuckerman of the National Center for Health Research, “It’s under fire in a way that is unprecedented in the last 20 years.”

Califf’s supporters point out that he is among the ten most cited medical authors in America, and that he has spent his career as a clinician helping patients. Regarding the danger of regulators being “captured” by their interactions with industry, Califf says, “The difference between capture and collaboration towards improving human health is a pretty big difference.”

The White House has set no time frame for its decision on Hamburg’s replacement. It has announced the acting commissioner will be Dr. Stephen Ostroff, a scientist and long-time official at the Health and Human Services department, when she steps down in March.

Letter to the Editor: "Keep the Medical Device Tax"

THE NEW YORK TIMES, FEBRUARY 13, 2015

Our research strongly supports your Jan. 30 editorial “No Case for Killing the Medical Device Tax”: Repealing the tax is indeed “a terrible idea” that solves a nonexistent problem. It could result in cutting health care programs that patients rely on.

Thanks to the Affordable Care Act, millions more Americans can now afford medical care that relies on devices like CT scans, cardiac implants or joint replacements. Our nonpartisan research center just released a report indicating that the device industry is thriving in the two years since the tax went into effect.

Stock prices increased an average of 66 percent for the largest United States-based device companies and even more for the smaller ones, much higher than the pharmaceutical companies, Nasdaq or the New York Stock Exchange.

Device companies’ sales and research and development also increased, and profit margins remained very strong. These data are consistent with the Congressional Research Service report that said the benefits of the health care law would help make up for the minimally negative effect of the tax.

Congress intended for industries that would benefit from the health law to help pay for it. The $29 billion raised from the device industry is far less than the amounts raised from other industries that benefit from the law, like drug makers and insurance companies. Why should those industries pay if the device tax is repealed?

The Hamburg legacy at FDA: accomplishments and controversies

By Ed Silverman. The Wall Street Journal. Published Feb. 5, 2015.

Link to original article here. 

Has the other shoe dropped?

Following mounting speculation, FDA commissioner Margaret Hamburg has told staffers that she will step down at the end of March, after a nearly six-year run heading the agency. The news comes just 10 days after the FDA hired Robert Califf, a widely regarded Duke University cardiologist, as deputy commissioner for medical products and tobacco.

That move quickly set off speculation that Califf would, in fact, soon succeed Hamburg, since he starts his new job later this month. And his new job involves overseeing a large swath of the agency – the FDA’s Center for Drug Evaluation and Research; the Center for Biologics Evaluation and Research; the Center for Devices and Radiological Health, and the Center for Tobacco Products.

An FDA spokeswoman declined to say whether a search was under way or, if so, how long the process may take. For now, FDA chief scientist Stephen Ostroff will temporarily assume command until a new commissioner receives congressional approval.

Hamburg, who has been one of the longest-serving FDA commissioners, presided over a string of accomplishments and controversies. A key mission from the start of her tenure was to bolster drug safety. There had been scandals over undisclosed side effect data for such medicines as the Vioxx painkiller and contaminated heparin that was imported from China and blamed for 81 deaths.

“It’s fair to say that Dr. Hamburg came to [the agency] at a time when the FDA was under a cloud,” says Peter Pitts, who was an FDA associate commissioner for external affairs before Hamburg’s arrived and is now a policy consultant to drug makers. “Whether or not the criticism the agency was receiving was fair (most of it was not) isn’t the point. Morale was low. Moral authority amongst constituents was fading.”

Despite efforts to bolster safety, Hamburg was widely criticized following an outbreak of fungal meningitis in 2012 that was traced to a compounding pharmacy and blamed for 64 deaths. Acknowledged as the worst U.S. public health crisis in decades, the FDA was accused of failing to properly oversee compounders, and Hamburg received some harsh grilling from members of Congress.

She was also chastised for her efforts to loosen rules governing conflicts of interest between industry and the outside experts who sit on FDA advisory panels. Hamburg complained that the rules – which set limits on financial ties, for instance – made it more difficult to attract qualified panelists, although she later backed away from this position. But some consumer advocates say her oversight remained lax.

“Too often, the FDA has succumbed to industry and political pressures, implementing policies and taking actions that tilt too far toward the bottom-line interests” of industry, says Michael Carome of Public Citizen, which regularly spars with the FDA over safety issues. He argues the FDA needs a commissioner who will be an “aggressive, proactive crusader.”

There was also controversy over an FDA decision to approve an opioid painkiller, even though it did not have tamper-resistant features and an agency advisory panel recommended against approval. The FDA argued that the drug, Zohydro, offered a needed option to pain patients, but Hamburg was chastised for allegedly overstating the number of people who may have benefited.

“Under Hamburg, the FDA approved a steady stream of new opioids despite an epidemic of opioid addiction caused by overprescribing,” says Andrew Kolodny, who heads Physicians for Responsible Opioid Prescribing and argues the agency has been too friendly to industry. “I’m pleased to hear that Hamburg is leaving.”

At the same time, Hamburg won plaudits for emphasizing programs, such as breakthrough therapy designations and accelerated approvals, which have sped drugs to market faster. This remains a hot-button issue, especially among patients who clamor for treatments for hard-to-treat and rare diseases. In recent years, the number of novel new medicines that FDA has approved has steadily increased.

The issue also resonates, of course, with the pharmaceutical industry, which benefits whenever drugs are launched more quickly. “These programs have proven invaluable in bringing groundbreaking new therapies to patients more efficiently, while maintaining the FDA’s high standards for safety and efficacy,” says Jim Greenwood, who heads the BIO trade group, in a statement.

Hamburg also was caught up in a highly charged political battle. In 2011, former Health & Human Services Secretary Kathleen Sebelius overruled an FDA decision to allow the Plan B emergency contraceptive to be sold over-the-counter to younger teenagers. The FDA maintained the treatment was safe. Two years later, the FDA was able to proceed and approved its use.

Such backbone will be missed by some, especially now and Hamburg’s departure comes at an unfortunate time, according to Diana Zuckerman, who heads the National Center for Health Research, a non-profit think tank. She worries that a sweeping law Congress is drafting called 21St Century Cures will have a detrimental effect on how medical products are regulated.

“Hamburg has been a strong voice for public health and this is a major loss at a dangerous time for the FDA,” she tells us. “The proposed legislation represents a frightening assault on the agency and the safety of medical products, and the FDA will need a strong leader to protect its public health mission.”

And in a statement, Ellen Sigal, who heads Friends of Cancer Research, a non profit, says Hamburg “changed the direction of the FDA, creating an environment of science-based collaboration that has fostered a new era of regulatory science focused on expediting the best treatments to patients.” We should note that various drug makers are among its supporters.

AND HERE IS THE MEMO THAT HAMBURG SENT TO FDA STAFF….

Dear FDA Colleagues:

It has been a privilege to serve as your FDA Commissioner for almost six years.  So it is with very mixed emotions that I write today to inform you that I plan to step down as FDA Commissioner at the end of March 2015.  As you can imagine, this decision was not easy.  My tenure leading this Agency has been the most rewarding of my career, and that is due in no small part to all of you – the dedicated and hard-working people that make up the heart of this Agency.  While there is still work ahead (and there always will be), I know that I am leaving the agency well-positioned to fulfill its responsibilities to the American public with great success.

I feel so fortunate to have worked at an organization as remarkable and productive as the FDA.  The expertise, dedication and integrity of our people and the unique nature and scope of FDA’s role make this Agency truly special.  Every day, FDA employees around the world recommit themselves to the Agency’s work, to quality science, to facilitating innovation, and to the protection of public health.  And because of your dedication and your service, we have been able to achieve so many significant milestones over the past years.

From creating a modernized food safety system that will reduce foodborne illness; advancing biomedical innovation by approving novel medical products in cutting-edge areas; and responding aggressively to the need to secure the safety of a globalized food and medical product supply chain, to taking critical steps to reduce the death and disease caused by tobacco, we have accomplished a tremendous amount in the last six years.  We can honestly say that our collective efforts have improved the health, safety and quality of life of the American people.

At the heart of all of these accomplishments is a strong commitment to science as the foundation of our regulatory decision-making and of our integrity as an Agency.  And while there are far too many significant actions, events, and initiatives to count, there are some highlights of the past years that I particularly want to mention.

In the foods area, we have taken critical actions that will improve the safety of the food Americans consume for years to come.  These include science-based standards developed to create a food safety system focused on preventing foodborne illness before it occurs, rather than responding after the fact.  We have taken several significant steps to help Americans make more informed and healthful food choices.  These include working to reduce trans fats in processed foods; more clearly defining when baked goods, pastas and other foods can be labeled “gluten free;” updating the iconic Nutrition Facts label; and, most recently, finalizing the rules to make calorie information available on chain restaurant menus and vending machines.

We have also made great strides in advancing the safety and effectiveness of medical products. Some of these important steps include new oversight of human drug compounding and provisions to help secure the drug supply chain so that we can better help protect consumers from the dangers of counterfeit, stolen, contaminated, or otherwise harmful drugs.  We are continuing to increase the speed and efficiency of medical product reviews.  We just had another strong year for novel drug approvals, with most of these drugs being approved on or before their PDUFA goal dates and most being made available to patients in the United States before they were available to patients in Europe and other parts of the world.  We launched a powerful new tool to accelerate the development and review of “breakthrough therapies,” allowing FDA to expedite development of a drug or biologic to help patients with serious or life-threatening diseases.  In fact, almost half of the novel new drugs approved in 2014 received expedited review with a combination of breakthrough designation, priority review and/or fast track status.  These included drugs for rare types of cancer, hepatitis C, type-2 diabetes and idiopathic pulmonary fibrosis, as well as a number of groundbreaking vaccines.  We have also established a regulatory pathway for biosimilar biological products that will create more options for patients.

On the medical device side, the average number of days it takes for pre-market review of a new medical device has been reduced by about one-third since 2010.  The percentage of pre-market approval (PMA) device applications that we approve annually has increased since then, after steadily decreasing each year since 2004.  We also published the Unique Device Identification (UDI) final rule that is intended to improve the tracking and safety of medical devices.  And we proposed a risk-based framework for laboratory developed tests (LDTs) to help ensure patients and providers have access to safe, accurate and reliable tests, while continuing to promote innovation of diagnostic tests to help guide treatment decisions.

We have ushered in the era of personalized medicine across all of our medical product centers. For example, many cancer drugs are increasingly used with companion diagnostic tests that can help determine whether a patient will respond to the drug based on the genetic characteristics of the patient’s tumor.  A growing percentage of our recent approvals have involved targeted therapies, offering many patients more effective response profiles and/or reduced likelihood of side effects.

We made significant progress in implementing both the letter and spirit of the Family Smoking Prevention and Tobacco Control Act.  Our tobacco compliance and enforcement program has entered into agreements with numerous state and local authorities to enforce the ban on the sale of tobacco products to children and teens; conducted close to 240,000 inspections; written more than 12,100 warning letters to retailers; proposed the extremely important foundational “deeming” rule; and broken new ground for FDA with the launch of the Agency’s first public education campaigns to prevent and reduce tobacco use among our nation’s youth.

As Commissioner, my goal has been to shape and support an FDA that is well-equipped to meet the challenges posed by scientific innovation, globalization, the increasing breadth and complexity of the products that we regulate, and our new expanding legal authorities.  I have worked hard to advocate for FDA and our unique and essential mission, including building new partnerships to support our work.  The Agency has received numerous votes of confidence with the bi-partisan enactment of a series of landmark bills extending our authority in the areas of tobacco, food safety and medical products.  In addition, we have achieved a dramatic increase in our budget, from some $2.7 billion in FY2009 to almost $4.5 billion in FY2015.

As hard as it is to leave this Agency, I am confident that the leadership team that we have in place will enable FDA to capitalize on, and improve upon, the significant advances we’ve made over the last few years.  Many of these leaders have been with the FDA throughout my tenure, and I am proud to say that we’ve recently made some wonderful new additions.

And with respect to the agency’s senior leadership team, I am pleased that Dr. Stephen Ostroff has agreed to serve as Acting Commissioner when I step down.  Since joining the Agency in 2013, and most recently serving as FDA’s Chief Scientist, Dr. Ostroff has successfully overseen numerous significant initiatives, while helping to ensure that scientific rigor, excellence and innovation are infused across the Agency.  I have every confidence that he will take on this new role with the same energy, dedication and care.

I want to extend my deepest gratitude to each and every one of you for your service and for making FDA an agency that is not only an exciting and rewarding place to work, but also a place of remarkably meaningful achievement and impact on the health and well-being of Americans.

Margaret A. Hamburg, M.D.

Commissioner of Food and Drugs
