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.

The research is published online by the journal Science at this week’s Science Express website.  » Read more...

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.  » Read more...

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.  » Read more...

Germany’s Institute for Quality and Efficiency in Health Care (IQWiG) this year put out several negative assessments of newly introduced drugs, stating the data did not prove “additional benefit” over existing treatments. In all cases, IQWiG came to the conclusion after deviating from the study design the companies had discussed with the regulators. Instead, IQWiG’s experts divided the patient population into subgroups, saying those subgroups needed different comparator treatments. As a result, these data were either not available or the subgroups were too small to demonstrate statistical significance.

One example is Pfizer’s Xiapex injectable collagenase, approved in early 2011 to treat Dupuytren’s contracture. IQWiG stated that Xiapex does not provide an additional benefit to patients because “it was not possible to derive such additional benefit from the dossier and because the manufacturer did not provide additional or suitable data” to substantiate the claim.

While the manufacturer had compared the Xiapex injection to a surgical treatment, partial fasciectomy (PF), IQWiG for its assessment established six subgroups of patients according to the severity of the disease and chose three different treatment options as comparator: no therapy, percutaneous needle fasciectomy (PNF) and partial fasciectomy (PF). As a result, IQWiG was able to state that Pfizer did not provide evaluable data because the company’s selected comparators differed from IQWiG’s comparators for all but one patient subgroup.  » Read more...

“Forget Alzheimer’s” is the title and the message of a book by German journalist Cornelia Stolze who is claiming to tell the “truth about a disease which isn’t one” (Cornelia Stolze, Vergiss Alzheimer. Die Wahrheit über eine Krankheit, die keine ist, Köln/Cologne 2011: Kiepenheuer & Witsch).

The book is strongly criticizing the handling of dementia, in particular Alzheimer’s disease (AD) in today’s medicine, pointing out the lack of adequate diagnostics and therapies and contrasting this sad reality with the often exaggerated promises of imminent breakthroughs by experts.

Stolze starts by explaining that to date, it is extremely difficult to diagnose Alzheimer’s disease. Most claims about new methods to confirm a diagnosis or, even better, to predict the onset have turned out to be false. She also points out that about 50 diseases and at least 150 medications may cause dementia symptoms. She concludes that most physicians are overextended to differentiate and often too early and too easily put the patient down as having Alzheimer’s, thereby impeding a causal treatment and condemning the patient to unnecessary mental derangement.  » Read more...
