Lung Cancer Concerns
On April 9, 2008, Pfizer announced in its "Dear Doctor" letter that Exubera may have been associated with lung cancer: of the 4,740 patients who used Exubera in clinical trials, six have developed lung cancer as of April 2008, compared to only one of the 4,292 patients in the placebo group. The association was not statistically significant, and Pfizer maintained in its letter that "Exubera remains a safe and effective medication."
In a letter 18 June 2008, Pfizer informed UK doctors of the above mentioned six cases, noting that they all had a prior history of cigarette smoking and that they were planning to investigate further the "observed imbalance in diagnosed lung cases" with an international observational trial. Pfizer's letter also stated that Nektar had stopped searching for a new marketing partner and therefore Pfizer would withdraw its Marketing Authorisation around September 2008.
