Nearly 15 years after trying an experimental drug on children in Nigeria during a deadly meningitis epidemic, Pfizer Inc. is still battling the legal claims brought by the children’s families; the families are still waiting for some sort of compensation; and, the case is still bogged down in pretrial motions.

A status hearing was scheduled in U.S. District Court in Manhattan Friday, but has been postponed indefinitely, as Pfizer continues to insist that the case should be dismissed. Pfizer attorney Joseph Petrosinelli, of Williams & Connolly in Washington, D.C., said he couldn’t comment on an ongoing case.
