How global regulations are written

In secret, during “trade” negotiations. Just one example: the 12 years of data exclusivity for biologics is currently US law, but that may get carved into stone in the new Trans-Atlantic Trade and Investment Partnership (TIIP). Once enshrined in a trade agreement, this rule and thousands more will be immune to change by any national democratic process.

Who participates in this process? Generally, only “cleared advisors” from the Fortune 500.

A partial (leaked) list of the initial bargaining positions for the EU are downloadable here. In the Initial Positions Papers, the EU notes that they have approved 16 biosimilars which have not yet been recognized as such in the US. Other topics include generic approvals, GMP inspections, and regulatory science for drug approvals.

All of decisions have immense potential impact for consumer welfare. My concern is the undemocratic lack of transparency for the entire process.

Overdose Prevention Marches On

Temple University Center for Public Health Law Research Leave a comment

By Scott Burris

Training lay people to reverse opiate overdose with naloxone continues to gain steam in the evidence base, popular media and legislatures. Here’s a great blog post the covers recent developments and links to a new film.  The Open Society Foundations and a group of harm reduction groups have launched a new website to promote these interventions.

This morning the House Energy & Commerce Health Subcommittee held the first of a series of hearings on prescription drug abuse.  ONDCP Director Kerlikowske & Dr. Doug Throckmorton of FDA have both testified and both discussed naloxone.

Meanwhile, last week, Vermont became the 13th state to pass a law expanding lay access to naloxone.

Our Bodies, Our Cells: FDA Regulation of Autologous Adult Stem Cell Therapies

Stem cells have been an endless source of fascination and controversy since Dolly the sheep was cloned in 1996. This month’s announcement of a cloned human embryo from a single skin cell [1] came on the heels of Sir John B. Gurdon and Dr. Shinya Yamanaka’s receipt of the 2012 Nobel for Physiology and Medicine for their work with induced pluripotent stem cells. Pluripotent stem cells can be embryonic or induced. Embryonic stem cells (ESCs) can generally be obtained from human embryos or by cloning embryos through somatic cell nuclear transfer (SCNT), as was done for Dolly.  Gurdon and Yamanaka demonstrated that pluripotent cells may also be formed by reprogramming adult cells to an embryonic state, resulting in induced pluripotent stem (iPS) cells without having to use eggs or cloning, or destroy embryos. However derived, pluripotent cells are capable of differentiating into virtually any cell type in the human body. This imbues them with great promise for scientific breakthroughs and medical advances, but also raises serious ethical, legal and safety concerns about their use.

Less controversial are “multipotent” adult stem cells (ASCs) which do not involve embryos or raise as many safety concerns as pluripotent cells.  ASCs are found throughout the body.  Their ability to differentiate is more limited than pluripotent cells but is vast nonetheless. The NIH’s clinicaltrials.gov site lists some 4500 ASC trials as compared with 27 for embryonic stem cells and 21 for induced pluripotent stem cells. Recent announcements of new stem cell treatments usually involve ASCs, such as last month’s news that a toddler born without a trachea received a new one made from her own adult stem cells.  It is therefore no surprise that ASCs have captured the attention of researchers, investors, physicians, patients and – increasingly – regulators, both here and abroad.

A growing number of physicians routinely offer treatments involving ASCs to their patients which can be performed in their offices.  Autologous adult stem cells, used to treat a variety of conditions, are harvested from the patient, processed, and returned to the same patient. It is no surprise that moving ASCs from laboratories to physician offices raises complex questions of law. We consider one of the more pressing ones: to what extent can the FDA regulate a physician’s ability to treat a patient with that patient’s own stem cells?  In the coming months, the D.C. Circuit Court of Appeals will hear oral arguments on this very issue in United States v. Regenerative Sciences.[2]

A Decade’s Quest for Safer Drugs: Congressional Committee Green Lights Regulation of Drug Supply Chains and Compounding Manufacturers

kvantassel Leave a comment

By Mary Ann Chirba and Alice A. Noble

On May 22. 2013, the Senate Health, Education, Labor and Pensions (HELP) Committee unanimously approved S.959, “The Pharmaceutical Compounding Quality and Accountability Act,” and S.957, “The Drug Supply and Security Act,” (now incorporated into S. 959 as an amendment).  Congressional efforts to enact comprehensive legislation to improve drug safety and secure the nation’s drug supply chain have lingered for over a decade. The lack of federal uniformity has allowed a patchwork of state legislation to emerge, attracting the less scrupulous to those states with the lowest security. The issue finally gained traction among HELP Committee members when 55 people died and 741 more became ill after contracting fungal meningitis from contaminated steroid injections made by the New England Compounding Center (NECC). Committee member Sen. Pat Roberts (R-KS) stated that given prior reports of problems with NECC, this tragedy could have been averted but for a “shocking failure to act” by NECC, state and federal regulators, and Congress.

As NECC’s role in the meningitis outbreak came to light,gaps in regulatory oversight did, too. The federal Food Drug and Cosmetic Act (FDCA)[1] currently recognizes only two categories of pharmaceutical manufacturers: commercial pharmaceutical companies and compounding pharmacies. To qualify as the latter under federal law, the entity must make individual or small batch, patient-specific drugs and do so only with a physician’s prescription for that patient.  Compounded drugs must be either be unavailable in the commercial market or needed in commercially unavailable doses or combinations. The FDCA exempts such compounders from its pre-marketing requirements applicable to commercially manufactured drugs. Thus, federal law clearly covers commercial pharmaceutical manufacturers, state law just as clearly oversees and licenses pharmacies but as the NECC case demonstrates, there is nothing clear about the responsibility for inspecting, licensing or otherwise overseeing compounders that do not fill prescriptions on a per patient basis.

Instead of compounding in response to an individual prescription, the New England Compounding Center made large batches of drugs for institutional buyers such as hospitals. Many of its drugs were commercially unavailable but some were knock-offs of marketed FDA-approved drugs – a practice which is clearly unauthorized. NECC’s business model was certainly not unique; neither was the limited and erratic response of state and federal regulators to complaints about the facility’s unsafe manufacturing practices. Congress knew that large-scale compounders existed along with concerns about their safety. Several members of the Senate HELP Committee had worked on curative legislation for over ten years, but made few inroads until the NECC crisis prompted the  HELP Committee to shift from park into drive.

GM Crops and the Environment

I’ve become increasingly interested in GM crops, in general, after the recent Petrie-Flom Conference on the FDA in the 21st Century.

I know there is a lot of discussion and controversy about genetically-modified (GM) crops.  I want to pick-up on a topic that is related to GM crops – that is, the environment.  The May 2nd issue of Nature includes a special section on GM crops.  Part of this section provides information on the environmental advantages of GM crops.  Most of the GM crops contain DNA that allows them to be resistant to herbicides or insects.  It turns out that a study showed that there was a 6.1% reduction in the use of herbicide between 1996 and 2011 on crops of herbicide-resistant cotton compared to the amount of herbicide that would have been used to treat conventional crops.  See Natasha Gilbert, A Hard Look at GM Crops, 497 Nature 24, 25 (2012) (I believe this article is free if you search for it on the Nature website).  A reduction in the amount of herbicide used to treat our fabric or food sources may have environmental advantages.  Less herbicide run-off into waterways.  Less herbicide for animals to consume.  See id.

Other scientific data provide inconclusive results about environmental impacts.  Some studies look at whether transgenes are spreading to weeds or non-GM crops.  For example, husbandry techniques of cross-breeding may unknowingly cross breed a non-transgenic line with a transgenic line and thereby create a transgenic line.  Now, a GM crop will be grown without the farmer even knowing it.  See id. at 24, 26.  And, if the GM crop has some sort of negative environmental impact, then a farmer may unwittingly be creating potential harm to the environment.

One thing I want to raise with this post is the importance to incorporate multiple areas of study – biology, environmental studies, genetics, health, regulation, etc. – to determine how we advance our understanding of GM crops.  I imagine that many readers of this blog are much more familiar with GM crops than me, so I welcome your comments.

Live Blogging FDA in the 21st Century Conference, Panel 9 – Addressing the Challenges of and Harnessing New Technologies

Holly Fernandez Lynch Leave a comment

Last but not least!  Our final conference panel focused on “Addressing the Challenges of and Harnessing New Technologies,” and was moderated by Fran Miller.

We heard first from Margaret Riley on “Twenty-First Century Technology with Twentieth Century Baggage: FDA Regulation of Regenerative Medicine.”  Riley explained that regenerative medicine (i.e., the use of pluripotent stem cells) has the potential to cure disease, injury, and even remedy organ shortages.  Of course, it is a hugely political issue and the debate is emotional, value-laden, and not necessarily logical.  As a result, the legislation/regulation that results in this area may be far from ideal.

Focusing on FDA specifically, Riley explained that the agency’s approach to stem cell regulation is rooted in its regulation of gene therapy and tissue products, as initiated in the 1990s.  FDA’s regulation of autologous stem cell therapies – in which a person’s own cells are removed, manipulated, and reintroduced – as a drug was recently upheld by the District Court of DC (US v. Regenerative Sciences, 878 F. Supp. 2d 248 (DDC 2012)), but is now on appeal to the DC Circuit. Riley is not sure what the outcome will be on appeal, but noted that getting BLA’s approved on a doctor-by-doctor basis will be very difficult and likely impossible.  One possible outcome of FDA regulation is likely to be off-shoring and stem cell tourism; ironically, strict regulation may end up not protecting patients, who will end up going abroad.

Next up was Nathan Cortez, who asked “Is the FDA Equipped to Regulate Mobile Health Devices?”

Live Blogging from FDA in the 21st Century Conference, Panel 8: Food, Supplement, and Tobacco Regulation

I. Glenn Cohen Leave a comment

[Live blogging off-the-cuff, so apologies in advance for any errors in summarizing, typos, etc]

Moderated by Emily Broad Leib, Harvard Law School

Robin Craig, Leslie Francis, and Erika George, University of Utah The FDA’s Authority Over Labeling: Current Ironies and Future Improvements:

Goal is to look at FDA authority over safety and labeling of Genetically Modified (GM) foods argue that FDA should do more, and argue for human right to food approach.

By GM we mean rDNA modification not husbandry and not careful selection.

FDA has moved to use guidance and policy. In particular two are relevant here. First, in food additives there is GRAS – Generally Recognized as Safe. E.g., Cinnamon was treated as GRAS. Manufacturers can self-determine a product is GRAS without notifying FDA, or, if in doubt, request a GRAS notice letter from FDA. This was proposed in 1997 and final review never issued, but this is how they do it. Has increased frequency of GRAS review request from FDA. But the process is voluntary and relies entirely on info from producer not scientific separate work by FDA.

In 1992, FDA issued a policy document related to GM foods. Stated no scientific evidence that GM foods have more safety concerns than existing husbandry techniques, so GM technology is NOT material information. This was NOT a conclusion that GM foods were GRAS.

In 1996, FDA issued a guidance for GM foods. Consultation process to determine whether there are material differences between GM version and non, voluntary process, encouraged to get consumer trust. Like GRAS totally voluntary, totally reliant on FDA data. 95 reported consultations between 1996 and 2012.

Alliance for Biointegrity v. Shalala, challenged in 2000 in D.D.C., court deferred to agency on safety questions and whether the info on GM was “material” and therefore needs to be disclosed.

Where would FDA get authority to regulate GM foods? May pose allergy risks? May be relevant to nutrition or quality. Maybe an additive not GRAS. But each of these arguments apply to specific GM food not GM foods as a whole.

Their argument: Consumers have a right to know so they can make their own consumption risks, and consumer or religious views are not merely preferences but a ground for the information that is material to consumers.

On why this is best understood as Human Right to Food. Adequate right to food is an HR right framed after WWII about enough food that is not adulterated and not against your faith or ethics (kosher, halal, vegan) and respectful of environment. U.S. is not part to Socioeconomic rights convention, which is most explicit protection of this right, but are signatories to other treaties that protect the right more indirectly.

Whole Foods has moved ahead on this as have others. Even if not a worry as GRAS, consumption may be inappropriate. We need a national strategy. More of a precautionary take that understands material to matter to consumers.

Jennifer Pomeranz, Yale, A Comprehensive Strategy to Overhaul FDA Authority for Misleading Food Labels:

Obesity and diabetes is the big problem in public health. And also people showing nutritional deficiencies because too much processed food. Current labeling is misleading makes people think food is healthier than they are. This is a unique public health problem. FDA has very weak authority and power here.
