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...
