Innovation Radar: Starving Cells Improves Chemotherapy

A few days of fasting may delay tumor progression and improve chemotherapy, a new study in mice reports. The findings indicate that fasting prior to chemotherapy treatment protects animals – and possibly humans – against the side effects of treatment. Here, Valter Longo and colleagues show in mice that fasting for 2 days in the absence of other treatments can delay the progression of different types of cancer, and may in some cases be just as effective as toxic chemotherapy drugs. However, the combination of fasting and chemotherapy appears to be more effective at making normal cells stronger (more able to resist damage from chemotherapeutic drugs) than either alone. In fact, combined fasting and chemotherapy promoted long-term, cancer-free survival in up to 40 percent of mice with neuroblastomas. Although clinical trials testing the effect of fasting in cancer treatment are still in early stages, these studies suggest that fasting cycles have the potential to boost the efficacy of chemotherapy. The results are particularly relevant for advanced-stage patients for whom standard treatment is ineffective.

Innovation Radar: Approved Drug Counters Effects of Alzheimer’s in Mice

An FDA-approved drug called bexarotene counters many of the effects of Alzheimer’s disease in mouse models, researchers report. The build-up of protein fragments called amyloid-beta is a key feature of the disease; everyone’s brain produces amyloid-beta, but in healthy individuals, enzymes break the fragments down, with help from a protein called ApoE. Paige Cramer and colleagues knew that bexarotene activates a protein that helps switch on the ApoEgene, and they hypothesized that the drug might therefore enhance the clearance of amyloid-beta in the brain. They gave the drug to mice engineered to have an Alzheimer’s-like condition and observed that levels of the protein fragments in the mice’s brains dropped substantially within just a few days. The mice also showed improvements in their cognitive, social and olfactory performance. Bexarotene, also known as Targretin, is currently used to treat a form of skin cancer and has a favorable safety profile, the authors note. The drug activates the nuclear receptor protein known as RXR, which binds one of two other nuclear receptors, PPAR and LXR. These receptor pairs then activate the transcription of the ApoE gene.

Company News: Achmea and LSP Launch LSP-Health Economics Fund for Innovation in Healthcare

Dutch healthcare insurer Achmea and investment company Life Sciences Partners (LSP) have set up an investment fund for innovation in healthcare, the LSP-Health Economics Fund (LSP-HEF). On 5 September 2011, the healthcare insurer already announced its intention to make € 50 million available for this purpose. As of today, the fund is ‘open for business’ and will seek to invest in international technology companies that may contribute to increased healthcare quality and better cost control.

The fund will be managed by Life Sciences Partners (LSP) a pan-European investment firm specialized in healthcare and biotechnology investments. LSP has recruited a dedicated investment team consisting of investment and technology specialists as well as experts for health economics and healthcare processes. The team will target European and US-based companies that have products close to or on the market. The main focus are companies offering promising technologies or products targeting indications such as cardiovascular diseases, lung disease, diabetes, cancer and dementia – diseases that more and more people are afflicted with and for which society pays a high price.

New technologies and products for these indications can lead to better control of health care costs while improve the quality of patient care, for example by using better diagnostics, applying minimally invasive treatments or preventing complications. In spite of this, it is the experience of Achmea and LSP that many of these companies struggle to penetrate the market quickly due to an insufficiently developed health economics case; this is often due to the fact that the technology has not been developed together with healthcare providers, not all stakeholders have been considered, and that a sales process that requires addressing each individual physician can slow down market take-up.

Through the unique cooperation between an insurance company and an investment firm, Achmea and LSP can efficiently support such companies in bringing their technologies to the market. Achmea will provide access to its know-how, expertise and database to help build the healthcare economics cases. Moreover, Achmea will help companies to find their way in the healthcare market, and will bring new technologies to the attention of healthcare providers.

Food for Thought: Germany Lags Behind in Biotech

These days, everybody has his own opinion about the quality and prospects of the German biotechnology industry. It even seems to be difficult to determine if biotech funding in Germany has increased, remained stable – or dramatically decreased, as recently published by the German industry organization BIO Deutschland.

If you look at key intangibles, such as the extent of media coverage on the biotech sector and the attractiveness of German biotech companies for investment banks, it is obvious that German biotech is not on the rise.

An article by Roland Benedikter and James Giordano published by German newspaper Die Welt suggests a bleak scenario if Germany is not willing to accelerate and intensify its biotech efforts. According to the authors, biotechnology is not only the most important success factor in future economic development – it will also change the global power balance: “the one who controls the chips also controls the game”. Asia and the Far East are quickly catching up in the biotech space, while the U.S. and other European countries continue to heavily invest into the sector. Therefore, Germany might gradually evolve from an export-oriented country to an import-oriented one – unless there will be a fundamental change of mind in the German government and society.

Almost two decades ago, the German biotech industry started out with the clear goal to narrow the gap to the U.S., where biotechnological markets and ventures were (and still are) much more mature. Since then, the German biotech sector has successfully produced a number of promising companies, innovations and products. However, the most attractive and advanced companies and technologies have been acquired by foreign, mostly U.S.-based, companies. Amgen´s take-over of Micromet, an oncology company with academic roots at the University of Munich, is the most recent example.

Therefore, lack of innovation is clearly not the problem. And lack of funding is only the symptom of an underlying German (and partly European) biotech phenomenon – wide-spread risk aversion combined with limited availability of true executive leadership qualities. Moreover, the public sentiment towards biotechnological innovation remains skeptical or even hostile and is mirrored by a “we don’t need this”-attitude of politicians and even Germany’s healthcare system, in which IQWiG, a decision body responsible for drug reimbursement, does its best to belittle innovative medicines.

It may not surprise you that an often-heard German term, “technologiefeindlich” (i.e. a negative attitude towards technological innovation), lacks any English equivalents.
