August 22, 2005. Increased media scrutiny Growing public concern over drug safety also has spurred the media to focus on this issue. Drug safety was the top issue in Pharmaceutical Executive’s Annual Media Audit 2005, with drug safety and development issues dominating more than half of the print media coverage (Exhibit 1). Heightened media and public 2 | Unlocking the power of pharmacovigilance awareness has combined with Exhibit 3: The downward safety spiral greater scrutiny by regulators and elected officials to create a rapidly evolving—and potentially dangerous—environment for pharmaceutical companies. One reason for such media scrutiny Upstream risks is the release of reports from the FDA and the World Health Organization’s Vigibase (a global adverse drug reaction database) of significant increases in the number of adverse events reported in recent years. The FDA, for example, shows an average growth rate of 12% annually in adverse event reports to the agency from 1995 through 2004 (Exhibit 2). The causes and implications of the increase are the subjects of much debate. Despite increases in adverse Business/financial Safety risks event reports, safety-based drug impacts withdrawals in the U.S. have remained essentially flat, at about 3 per 100 New Chemical Entity approvals for the past 35 years.1 The public may view the increase in reported adverse events negatively, but the growing number of reports may result, in part, from increased awareness in the medical community and the sheer increase in drug consumption. The industry could benefit greatly if the public better understood these factors and their impact on pharmacovigilance. The impacts of safety issues are not limited to perception alone. Safety issues can lead to regulatory fines, litigation costs, reduced market share, diminished brand equity, and decreased shareholder value. Such impacts may affect a company’s ability to finance safety initiatives and thereby induce a downward spiral of further safety-related strategic and operational issues (see Exhibit 3).
