The Kano trovafloxacin trial litigation arose out of a clinical trial conducted by the pharmaceutical company Pfizer in 1996 in Kano, Nigeria, during an epidemic of meningococcal meningitis. To test its new antibiotic, trovafloxacin (Trovan), Pfizer gave 100 children trovafloxacin, while another 100 received the gold-standard anti-meningitis treatment, ceftriaxone, a cephalosporin antibiotic. Pfizer gave the children a substantially reduced dose of the ceftriaxone (specifically, 33mg/kg) relative to that described on the US FDA-approved prescribing information. The allegation is that this was done to skew the test in favor of its own drug. Pfizer claimed that the dose used was sufficient even though a clinical trial performed by Médecins Sans Frontières recommends a dose of 50-100mg/kg.
