We now know the government’s Tamiflu stockpile wouldn’t have done us much good in the event of a flu epidemic. But the secrecy surrounding clinical trials means there’s a lot we don’t know about other medicines we take.

Ben Goldacre, The Guardian:  What the Tamiflu saga tells us about drug trials and big pharma

Today we found out that Tamiflu doesn’t work so well after all. Roche, the drug company behind it, withheld vital information on its clinical trials for half a decade, but the Cochrane Collaboration, a global not-for-profit organisation of 14,000 academics, finally obtained all the information. Putting the evidence together, it has found that Tamiflu has little or no impact on complications of flu infection, such as pneumonia.

That is a scandal because the UK government spent £0.5bn stockpiling this drug in the hope that it would help prevent serious side-effects from flu infection. But the bigger scandal is that Roche broke no law by withholding vital information on how well its drug works. In fact, the methods and results of clinical trials on the drugs we use today are still routinely and legally being withheld from doctors, researchers and patients. It is simple bad luck for Roche that Tamiflu became, arbitrarily, the poster child for the missing-data story.

And it is a great poster child. The battle over Tamiflu perfectly illustrates the need for full transparency around clinical trials, the importance of access to obscure documentation, and the failure of the regulatory system. Crucially, it is also an illustration of how science, at its best, is built on transparency and openness to criticism, because the saga of the Cochrane Tamiflu review began with a simple online comment.
