Dangerous Antibiotics for the 21st Century
No one can dispute that multidrug-resistant “superbugs” are a key public health concern for the 21st century. Better, safe and effective cures are needed. But the 21st Century Cures Act, legislation that will be voted on this week in the House, is not the solution to this problem.
Over 2 million people are infected with antibiotic-resistant bacteria each year, resulting in at least 23,000 deaths. New antibiotics have been slow in coming: No antibiotic with a truly novel mechanism of action has been discovered since the late 1980s. Yet this drought is not the fault of the Food and Drug Administration (FDA), which has long been under tremendous pressure to approve new antibiotics quickly. This pressure was increased even further by a 2012 law that accelerated review for qualifying antibiotics.
Thanks to the current review process for antibiotics, clinical development for these drugs is already quick by industry standards. A new antibiotic takes only seven years to get to market, compared with nine years for cancer drugs.
Quick approval is not without costs. Many of the antibiotics approved over the past decade have suffered from safety and effectiveness problems. For example, tigecycline (Tygacil), an antibiotic that received special accelerated FDA approval in 2005, was slapped with a black-box warning in 2013 stating that the drug increases the risk of death.
