The BMJ's open data campaign aims to achieve appropriate and necessary independent scrutiny of data from clinical trials. Working with others, we seek to highlight the problems caused by lack of access to data, and we welcome any suggestions on how to take things further.
The Tamiflu story
Our first open data campaign initiative relates to a public promise Roche made in 2009 to release full clinical trial reports in response to an investigation by the BMJ and Cochrane collaborators Peter Doshi and Tom Jefferson. 
The bottom line:
Releasing the trial reports would allow independent academics to answer questions about this globally stockpiled drug. To date, the full data set has not been provided.
This page links to others listing open correspondence with Roche, and the various bodies around the world which licence or recommend drugs. This open correspondence of letters offers readers the chance to witness attempts to compel greater accountability and responsibility in public health decision making and policy. The BMJ plans to launch other campaigns linked to its investigations in the future. Find out more about the background to Tamiflu and open data by reading this feature and accompanying editorial.
The MUGAS meeting has taken place, where questions about the quality of the data collected in Tamiflu trials was questioned. Trish Groves, BMJ deputy editor, took part in that meeting and has written a BMJ blog which describes the output.
Now the team behind MUGAS, including some of the original investigators of Tamiflu sponsored by Roche, will undertake a meta-analysis of both published and unpublished data. Concurrently, the Cochrane Neuraminidase Review Group have gained access to unpublished trials, and will be updating their own analysis previously published in the BMJ.

In October 2012 a bmj.com poll asked: "Who is mainly at fault for denying access to negative clinical trial results? The results are below:
What do you think?
We have created an interactive timeline that shows articles about Tamiflu which were published in the BMJ, between 2003 and 2012.
We have so far included the major influenza outbreaks, and will continue to add other external events.
