Art Caplan: Why do two white Americans get the Ebola serum while hundreds of Africans die?

As the WHO announced today that medical ethicists will convene next week in New York to discuss the use of experimental medicines in the West African Ebola outbreak, Art Caplan has a timely new opinion piece in the Washington Post asking why only white American victims of the Ebola outbreak have been treated with an experimental serum. Caplan argues that the decision was a question of economics:

The reasons for different treatment are partly about logistics, partly about economics and, partly about a lack of any standard policy for giving out untested drugs in emergencies. Before this outbreak, ZMapp had only been tested on monkeys. Mapp, the tiny, San Diego based pharmaceutical company that makes the drug stated two years ago: “When administered one hour after infection [with Ebola], all animals survived…Two-thirds of the animals were protected even when the treatment, known as Zmapp, was administered 48 hours after infection.”

But privileged humans were always going to be the first ones to try it. ZMapp requires a lot of refrigeration and careful handling, plus close monitoring by experienced doctors and scientists—better to try it at a big urban hospital than in rural West Africa, where no such infrastructure exists. […]

But it’s about more than logistics. Drugs based on monoclonal antibodies usually cost a lot—at least tens of thousands of dollars. This is obviously far more than poor people in poor nations can afford to pay; and a tiny company won’t enthusiastically give away its small supply of drug for free. It is likely that if they were going to donate drugs, it would be to people who would command a lot of press attention and, thus, investors and government money for further research—which is to say, not to poor Liberians, Nigerians or Guineans.

The Revival of Phage Therapy to Fight Antimicrobial Resistance (AMR) – Part III: What about patent protection and alternative incentives?

By Timo Minssen

In Part II of this blog on legal issues relating to the revival of phage therapy I discussed the US Supreme Court’s decisions in Myriad and Prometheus, which might present major obstacles to the patentability of phage-related technology (a more detailed analysis of the Myriad and Prometheus decisions is available here).

Yet, all is not lost. As indicated in Part II, Myriad does not directly affect the patentability of synthetically modified biological compounds and Prometheus would still allow patents on inventive applications of natural processes and correlations that add new features to “natural laws”. Thus there still seems to be considerable leeway for patenting within the area of page therapy.

One example, mentioned in a recent Nature article, could be the skillful selection and precise combination of different phages in order to attack one specific type of bacteria. Such selections, however, would face a tough battle to overcome the “additional features that add significantly more” and “not identical” thresholds set by Prometheus and Myriad. Another example with even better prospects for patentability relates to genetically modified phages that are – due to human intervention – enabled to target only specific bacteria. This technology was recently presented by MIT researchers at the 2014 American Society for Microbiology Meeting. The researchers led by Timothy Lu had genetically engineered phages that use a DNA-editing system called CRISPR to target and kill only antibiotic-resistant bacteria while leaving other susceptible cells untouched. The significant engineering and alteration of natural products and processes involved in such inventions would most likely meet both the Myriad and Prometheus standards.

Yet, while the USPTO has recently issued new patent eligibility guidance and the CAFC has begun to directly apply Prometheus and Myriad to reject patent claims in biotech cases (e.g. In re Roslin), many questions remain unsolved. In particular, it is still not sufficiently clear exactly how much modification is required to render a molecule or method sufficiently distinct from naturally occurring product and processes. And even if the patent-eligibility threshold could be met in extraordinarily circumstances, the claimed invention would still have to fulfil other patentability requirements such as novelty, non-obviousness and the written description-requirements. The threshold for these requirements, however, have been heightened in recent years (see e.g. KSR v. Teleflex (2007) , Nautilus (2014) etc.). Considering that phage therapy is almost a century old with a substantial common general knowledge and a state of the art employing routine methods, these crucial requirements might still prevent the patentability of many useful applications.

The Revival of Phage Therapy to Fight Antimicrobial Resistance – Part II: What about patent protection and alternative incentives?

By Timo Minssen

Three days ago I commented on a couple of legal issues raised in the recent Nature report “Phage therapy gets revitalized”  by Sara Reardon. One challenge concerns the reluctance of pharma companies to broadly invest in the development of phage therapies. As pointed out in the report, this does of course very much (but not only) relate to the question of patentability. Various aspects might present obstacles to the patentability of technology relating to phage therapy. To not complicate the discussion and considering recent developments I decided to focus on some of aspects under US patent law.

Like in Europe, the first door to patentability that phage-related technology would need to pass concerns patent eligibility. In the last years the US Supreme Court has rendered an astonishing number of fundamental patent-decisions, including not less than four (!) landmark judgments on patent eligibility, i.e. Bilski v. Kappos (2010), Mayo v. Prometheus (2012) , AMP v. Myriad (2013)  and Alice v. CLS (2014). Most relevant in this context are the decisions in Prometheus and Myriad.

Art Caplan: The Real Reasons for Worrying About Ebola

Art Caplan has a new opinion piece on NBC News responding to the recent media coverage of Ebola. He makes the case that although this has been the worst recorded outbreak of the disease, citizens of developed countries have little reason to panic:

Ebola is not going to run amok in downtown Boston, Cape May or Myrtle Beach or anywhere else in the U.S. It is running amok in poor African nations because local authorities did not have the will or the resources to respond quickly, because no one confronted local funeral customs that expose people to Ebola, mainly because the world did not care much if hundreds died in poor, politically insignificant nations.

The harsh ethical truth is the Ebola epidemic happened because few people in the wealthy nations of the world cared enough to do anything about it.

What are GM Foods?

By Joanna Sax
[Ed Note: Cross posted at HealthLawProfBlog.]

I read a lot of press and listen to the politics surrounding genetically modified (GM) foods; but it appears that there is a lack of understanding that almost all of our food supply is integrated with GM crops. I imagine that many readers of this blog already know this, so this may simply be background for some of you.

The focus of the debate appears to be on GM foods that contain some sort of exogenous genetic modification that allows them to be pest or insect resistant, either through DNA or RNAi. That is, a specific DNA or RNAi sequence is inserted into the seed that is known to interfere with a biochemical reaction that allows, for example, the crop to be resistant to a specific type of pest.

But, the reality is that almost all of our crops are genetically modified, if not through the insertion of exogenous DNA or RNAi, then through various husbandry techniques. For example, seeds may be hit with UV radiation, which causes double stranded DNA breaks and subsequent mutations. These seeds are then selected for desired traits, such as pest resistance or other hardy characteristics. So, then through husbandry techniques, the seeds are grown into crops with mutations to the endogenous DNA. For these crops, we know that they demonstrate some sort of feature that is desirable to the farmer (or consumer), but we have little idea about what other mutations they may carry.
