Nigeria: Court allows summons in Pfizer drug trial

A Nigerian court allowed the federal government on Wednesday to serve a summons on U.S.-based drug maker Pfizer Inc to defend itself against a $6.5 billion lawsuit over a drug trial. The federal government and the northern Nigerian state of Kano are suing Pfizer for a combined $8.5 billion in damages over the 1996 trial of Trovan, a new drug tested on children during a meningitis epidemic.
