Medical Marketing and Media - Clarinex approval sets FDA precedent

Mo. The FDA’s approval of Schering’s Clarinex (desloratadine) on December 21 for “the relief of the nasal and non-nasal symptoms of seasonal allergic rhinitis in patients 12 years of age and older” broke an internal policy precedent by being based not on an FDA preapproval inspection of the plant that will make the drug, but on an audit of that plant done for Schering by an outside consultant. The facility, in Las Piedras, Puerto Rico, was audited by Lachman Consultant Services Inc., of Westbury, N.Y. The FDA has not said why it did not inspect the plant itself. However, at the time of the approval the agency was reported by Schering to be negotiating a federal court consent decree over manufacturing quality problems at a number of the company’s other facilities. The FDA’s last inspection of the Las Piedras plant was in June, 2001 and it resulted in a list of 15 manufacturing deficiencies being drawn up by the inspectors.
