Pfizer issued the following statement in response to legal action taken against the company by the Nigerian government. Pfizer continues to emphasize—in the strongest terms—that the 1996 Trovan clinical study was conducted with the full knowledge of the Nigerian government and in a responsible and ethical way consistent with the company's abiding commitment to patient safety. Any allegations in these lawsuits to the contrary are simply untrue—they weren't valid when they were first raised years ago and they're not valid today.
