Deep dive
Neimeth International Pharmaceuticals Plc is the institutional successor of Pfizer Products Plc Nigeria. Pfizer indigenised its Nigerian subsidiary in 1997 and renamed it Neimeth (Nigerian-German Chemicals, an earlier predecessor brand). The 1996 Kano Trovan meningitis-trial controversy — in which Pfizer-administered investigational antibiotic Trovan was tested on children at the Kano Infectious Diseases Hospital during the meningitis outbreak, leading to deaths and injuries and a multi-year international litigation — is recorded under the Pfizer-Trovan settlement, ultimately resolved with the Kano State government in 2009 for $75m.
Controversies & accountability
- · The 1996 Pfizer Trovan trial in Kano — conducted by Pfizer on 200 children during the meningitis epidemic — remains the most litigated pharmaceutical episode in Nigerian history. The 2006 Federal Government investigation panel (Abdulsalam Nasidi) found the trial had been conducted without informed consent and in breach of Nigerian and international research ethics. The Federal and Kano State Governments separately sued Pfizer; Pfizer settled the Kano case in 2009 for $75m and the Federal case in 2011.
