In another step to require prompt reporting of clinical trial data, the US Food and Drug Administration (FDA) has sent a letter to GlaxoSmithKline demanding that the company supply a full report on the results of postmarketing studies conducted for the diabetes drug, Avandia (rosiglitazone maleate). The demands are contained in a Warning Letter dated 25 March 2008 to Jean-Pierre Garnier, GSK’s chief executive officer. The letter has been posted on the FDA’s website, www.fda.gov.
