Food for Thought: Weekly Wrap-Up

In Frankfurter Allgemeine Zeitung (FAZ) Martina Lenzen-Schulte this week reports about an oncology symposion in Wiesbaden/Germany that dealt with oncology patients increasingly turning towards alternative medicines – 40 to 70% according to recent estimates. Oncologists now start to notice they cannot ignore patents’ needs and hopes, and therefore a number of clinicians have turned to looking at available studies on complementary medicine to separate the wheat from the chaff. However, it turns out that many of these studies – on mistletoe therapy as well as on dietary recommendations – are insufficient to provide sound evidence.

Werner Bartens in Sueddeutsche Zeitung features a 3,700 patients study published in the Journal of the American Medical Association demonstrating that contrary to common wisdom low salt diets increase the risk of heart attacks and stroke.

In Wirtschaftswoche, Susanne Kutter introduces the Diapat diagnostic test developed by German biotech company Mosaiques DiaPat GmbH that analyses more than 6,000 different peptide and protein molecules in human urine in one run. The test can be used to diagnose and even predict the onset of diseases. It has just been approved by FDA for the diagnosis of renal diseases. Already, the company markets a prostate cancer urine test in Germany. Mosaique’s test, Kutter claims, is but one of the many achievements to come from proteomics. She adds that the tests will have the potential to save the healthcare system billions of Euros.

Haydn Shaughnessy in Forbes states the record of cancer treatment still looks poor, with cancer mortality not improving a lot – as for example compared to heart diseases. Likewise, many preventive measures such as exercise and low fat diets don’t work. Shaughnessy therefore makes the case to support crowdsourcing approaches to develop a cancer cure like Pink Army and Cancer Commons (see akampioneer’s earlier entry on Open Source Principles – a Concept for the Life Sciences?). Also in Forbes, Matthew Herper forecasts that Pfizer will break itself up and spin out companies soon.

Eric Pfanner in New York Times looks at new European ventures to fill a void in world news after so many news organizations are laying off journalists or closing shop. As examples, he introduces Worldcrunch, a web-based start-up translating newspaper articles from around the world into English and Presseurop which translates into other languages, too.

In the New Scientist Jessica Hamzelou writes that people easily distracted might have more grey matter in their brains than focused people. In a separate article, she also features a pacemaker-like, implantable device that can deliver timed doses of medications for a year. Boonsri Dickinson, also in New Scientist, interviews nobelist Eizabeth Blackburn, the co-discoverer of the telomerase enzyme and its role in aging. Blackburn co-founded biotech company Telome Health, which is now starting to sell a test for telomere length. While at present it is sold for research purposes, e.g. to know more about telomer length as markers of aging, the test will be offered to the public through physicians for $200 later this year. Ferris Jabr in New Scientist introduces an approach fastening nanocapsules filled with interleukins to T cells as a way to cure cancer. So far, it seems to work in mice.

And here our favorite quote from Matthew Herper’s blog, who recently mused about whether entrepreneurs share some genetic characteristics, and if so, whether one could invent an antibody to turn someone into an entrepreneur: “‘Entrepreneur Antibody:’ Serious Side Effects Might Include Visual Hallucinations of Venture Capital.”

And finally, Norbert Lossau in Die Welt features a study by LinkedIn into the most common given names of CEOs, finding that in Germany they are Wolfgang, Christoph and Michael. In France, Gilles is number one, while it is Charles in the UK, Ray in Canada, Guido in Italy and Howard in the US. Marketing people often have short names like Chip, Todd or Trey, while engineers seem to have much longer give names. So think twice before naming your next newborn!

Food for Thought: Moving Into the Clinic Without Animal Toxicity Tests

This month, MedNous provides an in-depth case study on an immune therapy developed by Immunocore Ltd. that won approval from the British and US regulators MHRA and FDA to start clinical trials on the basis of in-vitro safety studies only – without conducting any toxicity tests in animals.

The product in question, IMCgp100, is a monoclonal T cell receptor fused to an anti-CD3 single chain antibody fragment. The molecule is tricky in that both binding sites bind to human proteins and cells only. As a result, animal studies would have been without any predictive value. The company therefore had to design a reliable preclinical test for predicting the behavior of the drug in humans.

This has been a particular challenge as regulators still were digesting the shock from the TeGenero disaster in 2006, when six healthy volunteers almost died from cytokine storm in a Phase I clinical study of an immune therapy. Back then, the drug had been tested in animals and the volunteers received only a fraction of the dose that had been safely administered to monkeys.

After intense consultations with the regulators, Immunocore conducted a battery of tests on human cells to find out about potential cytokine release, cross-reactivity, etc. The company, too, tested whether hormones were able to shut done activity of the drug in case something would go wrong during the trials.

Trials are on the way already at three UK and two US sites in patients with metastatic melanoma and Immunocore hopes to have preliminary data, including some efficacy results, by 2012.

Food for Thought: Weekly Wrap-Up

Can bioplastics, which is derived from renewable resources and biodegradable, become an alternative to conventional plastics made from mineral oil? Not yet, writes Nina Weber in Der SPIEGEL. Cultivation of raw material needs pesticides and fertilizers and the predominant bioplastics used to date is made from polylactic acid (PLA), which is biodegradable only at high temperatures. The prospects may become better – but only if PLA can be derived from plant remains and if enough PLA is on the market so that recycling is profitable.

Gardiner Harris in The New York Times reports on flaws in a widely cited lung cancer study involving more than 50,000 patients. The study’s conclusion that  80% of lung cancer deaths could be prevented through wide use of CT scans made the headlines in 2006. Now it seems that the researchers are unable to locate 90% of the consent forms so that  a confidential report evaluating the study on behalf of the lead study center recommend that the trial be stopped already in 2008. The study is still ongoing.

The New Scientist reports on findings that the malaria parasite Plasmodium falciparum can be killed by kinase inhibitors, common anti-cancer drugs. In in-vitro experiments at Lausanne Federal Polytechnic in Switzerland researchers exposed malaria-infected liver and blood cells to kinase inhibitors and observed that some of these compounds selectively killed the parasite, but not the cells.

Also in New Scientist, Ahmed Zewail, who won the Nobel prize in chemistry in 1999, claims that the Middle East is ripe for a scientific revolution.  At present, he states, Arab, Persian, and Turkish scientists as a group are underperforming as compared to colleagues in the West or Far East. Zewail thinks that the recent revolutions will open the door to improve on literacy, women’s participation and education and bear the chance to remove red tape and allow freedom of thought. He calls on partnering with Muslim countries to establish centers of excellence in science and technology.

Finally, Alex Knapp in Forbes introduces Justin, an impressive humanoid robot made in Germany by DLR, the German aerospace agency. So far, this incredible piece of German hard- and software engineering is used to catch two balls at once while making coffee. the akampioneer very much hopes he will learn better tricks to avoid the “invented in Germany, marketed elsewhere” pitfall.
