Drug Policy

Trump’s New Policy to Tackle Sky-High Drug Prices Makes Sense — Sort Of

Tackling high prescription drug prices was a repeated promise of the Trump campaign. The Trump administration has now taken its first step towards fulfilling this pledge, outlined in a blog post by Food and Drug Administration (FDA) commissioner Scott Gottlieb. The agency will pursue a Drug Competition Action Plan, whose goal will be to eliminate obstacles to the development of cheap generic drugs – particularly those caused by loopholes in existing FDA policies, which are exploited by pharmaceutical companies to extend their patent exclusivity period and maximize profits. An example of such ‘gaming’ the system, cited in the post, is the practice of limiting access to branded products for comparative testing by generic developers. Ultimately, the FDA will work closely with the Federal Trade Commission (FTC) to address such issues, since directly regulating business practices is outside its mandate.

On its face, the FDA’s effort is a step in the right direction. Availability of generics reduces the cost of medications by over half within the first year, and according to a recent Congressional report, manufacturers state that ‘competition…is the primary driver of generic drug prices’. However, it ignores evidence that the real driver of increased drug spending is new, branded medicines, not overpriced generics. In fact, early indications are that Trump’s policies will favor the pharmaceutical companies that produce such medicines, by reducing regulations and apparently abandoning his promise to enable the government to negotiate drug pricing through Medicare. Overall, these actions signal a commitment to promoting free market mechanisms in the pharmaceutical industry; time will tell whether this approach will actually lead to more affordable drugs.

Cancer

In a Major Shift, Cancer Drugs go ‘Tissue-Agnostic’

With the landmark approval of Keytruda in May, the Food and Drug Administration (FDA) appears to have ushered in a new era of cancer drug development.  So far, cancer treatment and drug evaluation have largely used the tumor’s tissue of origin as a starting point. Keytruda (an immune system enabling drug developed by Merck and approved for melanoma in 2014) marked the first departure from this approach, receiving priority approval to treat any solid tumor containing a mutation in the mismatch repair pathway, regardless of context. Recently released data suggests that another tissue-agnostic cancer therapy is on the way: larotrectinib (a cell growth inhibitor developed by Loxo Oncology) showed high efficacy for any tumor with a certain biomarker (TRK fusion). Several other such drugs, whose indications will be based on tumor genetics rather than location, are in the clinical pipeline.

Although these advances have generated significant excitement in the cancer community, some caveats exist. First, identifying the patients that could benefit from tissue-agnostic treatments will require individual initiative and depend on the cost of screening, particularly when considering markers that are rare for a certain tumor type. A potential solution is suggested by the NCI-MATCH trial, part of the NIH’s Precision Medicine Initiative (PMI) – in it, patients can enroll in one of several parallel clinical trials if a corresponding drug-targeted mutation is found in their tumor’s genome. If these trials prove effective, patients could eventually be regularly matched with a personalized, tissue-agnostic, biologically valid treatment, based on a standardized screen.  Second, researchers caution that tissue-agnostic studies should have a strong scientific rationale and/or breakthrough-level efficacy. Otherwise, such efforts ‘could actually slow drug development if there are differential effects across tumor types by diverting resources from enrolling patients in a predominant population or in the tumor type most likely to respond’.

Despite these concerns, the tissue-agnostic paradigm offers great promise for cancer patients. NIH-funded resources such as The Cancer Genome Atlas could be invaluable to this field moving forward. (Ken Garber, Science)

Scientific Publishing

US Court Grants Elsevier Millions in Damages from Sci-Hub

A New York district court has awarded academic publishing giant Elsevier $15 million in damages from Alexandra Elbakyan, founder of the website Sci-Hub, for copyright infringement. Elbakyan, a 27-year-old neuroscientist turned programmer, started Sci-Hub in 2011 with the goal of ‘remov[ing] all barriers in the way of science’. The site allows users to download research papers that would normally be blocked by a paywall, by obtaining credentials from subscribing institutions and using them to access publisher-run databases like ScienceDirect. Over 60 million papers are posted on Sci-Hub, and users downloaded 28 million articles in 2016.

Elbakyan’s case is reminiscent of Aaron Swartz, another high-profile champion of open access to scientific research. Faced with federal charges related to his hacking of journal archive JSTOR, Swartz tragically committed suicide in 2013. Both Elbakyan and Swartz found publishers’ ability to profit from restricting access to scientific literature, effectively withholding knowledge from anyone outside of a privileged inner circle, as well as the legal protection provided to this system, to be deeply unethical. Their willingness to act upon these convictions has earned each a sizable following in the scientific community.

For their part, publishers claim that fees go towards overhead, and point to significant efforts to expand free and open access programs. While judges have so far been sympathetic, Elsevier’s legal battle has been largely one-sided. Elbakyan has been ignoring rulings requiring her to shut down Sci-Hub since 2015, opting to simply change domains instead, and since she is currently based in Russia and has no American assets, she is unlikely to pay any damages.

The Trans-Pacific Partnership and its Impact on Pharmaceutical Affordability

leave a comment »

By: Shakira M. Nelson, PhD, MPH

        For many, the Trans-Pacific Partnership (TPP) was a point of great debate during the 2016 Presidential primaries and election. As a simplified explanation, the TPP is a free-trade agreement involving the United States, Canada, Australia, Japan, New Zealand, Mexico, Chile, Peru, Brunei, Malaysia, Singapore and Vietnam, intended to “level the trading playing field” through the elimination of tariffs and other laws that create trade barriers. In its final form, the TPP would impact up to one-third of world trade and 40% of the global gross domestic product. Many who debated the ramifications of the TPP did so in the context of foreign policy interests. Although aligned with foreign policy, a major part of the TPP deals with intellectual property protection, and pharmaceutical drug development. If implemented, the effects of the TPP could greatly diminish public access to affordable medicines, both domestically and internationally. Moreover, the stronghold the TPP places on intellectual property could limit the development and marketing of less expensive options.

Intellectual property can be divided into two categories: industrial property and copyright. Patents, trademarks, and industrial design fall under industrial property. Patent development is a large part of scientists’ work, seen as almost a necessity to incentivizing innovation. Many argue that, without the ability to patent inventions and significant findings, scientists would not be able to generate profits used to sustain research and development; within the pharmaceutical industry, patents are the proverbial bread-and-butter. When in place, patents create a stronghold around the release of new chemical drugs, which prevents competition by generic brands. The standard length of time of a patent for a chemical drug is 20 years, which starts from the time the drug is invented.

Many new medicines under development today fall under the category of ‘biologics’. As the name suggests, biologics are treatments made from biological sources, and are very different from chemical drugs. Created to treat a multitude of diseases, including Ebola and cancer, biological sources include vaccines, anti-toxins, proteins, and monoclonal antibodies. Given their structural complexity compared to traditional drugs, and use of recombinant DNA technology, biologics are more difficult, and costlier to make. Moreover, manufacturers have a greater burden in ensuring product consistency, quality, and purity over time. This is done through certifying that the manufacturing process remains the same over time. Because of this, it is estimated that the price to manufacture biologics cost on average more than 22 times the price of chemical drugs. Current laws state that generic biologic development, known as biosimilars, cannot be approved until 12 years after the branded product has been approved – this is known as an exclusivity period. This was enacted under the Biologics Price Competition and Innovation Act of 2009, by the Food & Drug Administration (FDA).

The challenge with current policies is establishing a period-of-time that balances the need for companies to generate profits and cash flows, which will incentive them to conduct more research and compensate them for the extensive manufacturing processes, with the need to provide greater access through launching generic drugs and biosimilars. The trouble with the proposed policies of the TPP agreement is that they seem to embolden the pharmaceutical companies by introducing changes that would prevent competition from generics and biosimilars for longer periods of time than the current basic terms. The implications of this are far-reaching, as it may lead to a significant increase in the current costs of pharmaceutical drugs and biologics, hindering the health of the patients who rely upon these treatments.

Critics of the current system of patent length and biologic exclusivity periods fear that rather than incentivizing innovation, companies are being rewarded through their ability to charge higher amounts for drugs without the fear of competition on the market. Health policy experts concur, identifying policies such as the Hatch-Waxman Act of 1984 in allowing for the creation of drug monopolies, and “going too far in compensating the pharmaceutical industry at the public’s expense”. A report released in 2009 by the Federal Trade Commission stated that biosimilar development was more difficult to achieve than traditional generic drugs. For example, development requires comparisons to the original biologic, to prove efficacy and equivalence. Biosimilars must share the same mechanism of action, with no clinically significant differences in terms of safety or potency for the approved condition of use. The steps necessary to achieve this are significant, and therefore imposing a 12-year exclusivity period on biologics may be unnecessary. US Congressmen have pushed to compromise, floating an amendment to the TPP that would lower the exclusivity period to 8 years. However, critics and patients who rely upon drug competition to lower market prices, have protested this amendment stating that costs of new drugs and biologics are too high, and 8 years is too long of a length of time to wait for affordable generics and biosimilars to come on to the market.

The impact of decreasing the length of time it takes for biosimilars to come onto the market can be seen with Neupogen, a leukemia drug that was first approved by the FDA in 1991. Delivered via injection, Neupogen costs patients $3,000 for 10 injections. With injections needed daily, this drug could carry a price tag of well over $100,000 per year. It wasn’t until recently, however, that the first biosimilar was approved on the US market. The biosimilar, Zarxio, was approved as a leukemia drug and is priced at more than $1000 less than Neupogen. This pricing has the potential to decrease the yearly costs of this drug from $100,000 with Neupogen to $55,000-$75,000. Further evidence of these financial savings was provided by the Rand Corporation, which predicted a savings of over $44 billion over 10 years with an increased approval of biosimilars, for patients who rely upon these specific cancer treatments.

Internationally, the policies of the TPP also have far reaching effects on the availability and costs of pharmaceuticals. The 12-year exclusivity period would be imposed upon the other countries involved in the TPP, where currently for some, such as Brunei, there is no current exclusivity protection. By imposing the 12-year period, global competition could become restricted. Additionally, the TPP proposes other key patent protections that play a bigger role on the international market. One protection, known as evergreening, allows drug companies to request patent extensions for new uses of old drugs. The immediate effect of this is an extension of monopolies on drug sales for minor reasons. The second protection allows pharmaceutical companies to request patent extensions if it takes “more than 5 years for an application to be granted or rejected.” Advocacy groups fear that the price of drugs would undermine the efforts of health initiatives, such as the Global Fund to Fight AIDS, Tuberculosis, and Malaria. These initiatives rely upon price competition to manage costs, with the availability of cheap generics helping drive costs down.

Although the current administration has ended the USA’s association with the Trans-Pacific Partnership, it is important to note that other countries may try to implement some of the policies, affecting the availability and affordability of drug treatments. To decrease this burden, the US could work to assist in negotiating exceptions for the poorer and smaller countries, to help them meet any challenges they may come up against. Within the US itself, it is important for policies, laws and any future trade agreements to be modified, with more of a focus on the affordability and regulation of drugs and biologics. Imposing price controls may offer a modest benefit, but may not be a long-term solution. A focus on lowering the patent length for new drugs and biologics can be an immediate step. Although the push back from pharmaceutical lobbyists will be substantial, alleviating the financial burden on families afflicted with cancer and diseases should be the focus.

Drug pricing

After the price gouging by Turing, competitor announces it will offer $1 pill

Martin Shrkeli became infamous after he became CEO of Turing Pharmaceuticals and skyrocketed the price of a Daraprim pill, used to treat toxoplasmosis, from$13.50 to $750, a price hike of over 5000%! At that price, the Infectious Diseases Society of America had estimated that it would cost $336,000/year to treat a patient with toxoplasmosis. Turing acquired marketing rights for Daraprim from Impax Laboratories in August for $55 million; though it had initially been made and sold by GlaxoSmithKline for $1 a pill. The United States has no price control on medicines even though in they are common in Europe.

This move by Shrkeli and the news that other drug makers have bought the rights to old, cheap medicines that are the last resort for serious diseases subsequently raising prices has not only angered patients and physicians. It has triggered government investigations, heavy scrutiny by the media and a plunge in biotech stock prices, as well as becoming a political talk point in the upcoming election to fight “price gouging”.

However, there is a new player in the field. Imprimis Pharmaceuticals announced that it can make a ‘close, customized version’ of Daraprim for about $1 per pill. A current caveat is Imprimis’ formulation itself is not FDA approved, and can only be used when prescribed by a doctor for a particular patient. Imprimis CEO, Mark Baum, released the following statement that “Imprimis is forming a new program called Imprimis Cares which is aligned to our corporate mission of making novel and customizable medicines available to physicians and patients today at accessible prices.” (Maggie Fox, NBC news)

Infectious Diseases

Yersinia pestis has been plaguing humans for over 3000 years

In a recent article published in Cell, Rasmussen et al. published that the plague-causing bacteria Yersinia pestis (Y. pestis) DNA was found in human teeth from Asia and Europe dating from the Bronze Age or ~2500-5000 years ago. This is well before any record of plague. These scientists examined over 100 human skeletons and found that the teeth in seven tested positive Y. pestis DNA. The oldest skeleton was 5783 years old! The authors suggest, “plague may have shaped early human populations.” Their data implies that Y. pestis did not become the flea-borne mammalian pathogen it is today (by acquiring the ymt gene), until sometime in the first millennium BC, well before the historically recorded plagues. (Simon Rasmussen, et al, Cell and James Gallager, BBC News website)

Global Health/Infectious Diseases

Interview with Margaret Chan, director general the World Health Organization

On October 14, 2015, Kai Kupferschmidt, a contributing correspondent for Science, had the opportunity to interview the director general of the World Health Organization, Margaret Chan.  The previous week was the first week that there was not a single new case of Ebola reported. This Ebola outbreak has killed over 11,000 people in almost two years.

During the course of the interview, two discussed many aspects of the current outbreak, including the lack of an initial response and how critical it is to get proper resources to those who need most. She stressed that countries impacted by an outbreak should report the disease while countries not affected by the outbreak should not impose their own trade or travel restrictions other than those recommended by the WHO. Chan has said to the WHO’s member states, “If you want WHO to be strong and fit for purpose, keep your promises. Put your money where your mouth is.”

Unfortunately, the WHO reported two new cases of Ebola in Guinea only two days after the interview on October 16, ending a two-week period in which no new cases had been detected across West Africa. The WHO does not consider a region Ebola-free until 42 days, or double the potential incubation time, have passed without a new case. The other two countries, Liberia and Sierra Leone, which were also heavily impacted by this outbreak, are further out from their last reported cases: Liberia is has met the deadline and is considered Ebola-free, while Sierra Leone is over halfway through the 42 day time period. The 42-day guideline may in fact be just that ‘a guideline’ as the Ebola virus has been isolated from seminal fluid 82 days after symptom onset. (Kai Kupferschmidt, Science)
