http://news.independent.co.uk/world/science_medical/story.jsp?story=471131...it has been an open secret within the drugs industry that most drugs do not work for most patients, a secret that has now been publicly aired for the first time by Allen Roses, the head of genetics at GlaxoSmithKline, Britain's biggest drugs company.
It found that drugs vary enormously in terms of how well they work, with efficacy rates varying from as low as 25 per cent for cancer drugs to 80 per cent for painkillers.
For many drugs, however, the efficacy rates hover around 50 per cent or lower, meaning that, for most people, these drugs just don't work. As Dr Roses puts it: "The vast majority of drugs - more than 90 per cent - only work in 30 or 50 per cent of the people."
"Roses is a smart guy and what he is saying will surprise the public but not his colleagues," said one industry scientist. "He is a pioneer of a new culture within the drugs business based on using genes to test for who can benefit from a particular drug."

http://news.independent.co.uk/world/science_medical/story.jsp?story=471139Allen Roses, worldwide vice-president of genetics at GlaxoSmithKline (GSK), said fewer than half of the patients prescribed some of the most expensive drugs actually derived any benefit from them.
Drugs for Alzheimer's disease work in fewer than one in three patients, whereas those for cancer are only effective in a quarter of patients. Drugs for migraines, for osteoporosis, and arthritis work in about half the patients, Dr Roses said. Most drugs work in fewer than one in two patients mainly because the recipients carry genes that interfere in some way with the medicine, he said.
"The vast majority of drugs - more than 90 per cent - only work in 30 or 50 per cent of the people," Dr Roses said. "I wouldn't say that most drugs don't work. I would say that most drugs work in 30 to 50 per cent of people. Drugs out there on the market work, but they don't work in everybody."
