Business Ethics on a Global Scale. In the 1990s, Pfizer, Inc., developed a new antibiotic called Trovan (trovafloxacin mesylate). Tests showed that in animals Trovan had life-threatening side effects, including joint disease, abnormal cartilage growth, Liver damage, and a degenerative bone condition. In 1996, an epidemic of bacterial meningitis swept across Nigeria. Pfizer sent three U.S. physicians to test Trovan on children who were patients in Nigeria's Infectious Disease Hospital. Pfizer did not obtain the patients' consent, alert them to the risks, or tell them that Médecins Sans Frontières (Doctors without Borders) was providing an effective conventional treatment at the same site. Eleven children died in the experiment, and others were left blind, deaf, paralyzed, or brain damaged. Rabi Abdullahi and other Nigerian children filed a suit in a U.S. federal district court against Pfizer, alleging a violation of a customary international law norm prohibiting involuntary medical experimentation on humans. Did Pfizer violate any ethical standards? What might Pfizer have done to avert the consequences?
