The Drug-Resistant Threat: Incentivizing New Antibiotics

In 2012, Margaret Chan, Director-General of the World Health Organization (“WHO”), suggested that we are entering a “post-antibiotic era,” meaning that “[t]hings as common as strep throat or a child’s scratched knee could once again kill.” (Forbes)  The evolution of antibiotic resistant bacteria has led to the deaths of at least 23,000 annually in the U.S..  Terrifyingly, most of the infections causing these deaths, or deaths complicated by an antibiotic-resistant infection, occur within “healthcare settings such as hospitals and nursing homes.” (CDC – Threat Report)  Unfortunately, pharmaceutical companies have been loath to invest in antibiotics to combat the growing problem simply because it is not profitable, causing a steady decline in new antibiotic drug approvals. (CDC – US Threat)

The problem has not gone unnoticed by the Food and Drug Administration (“FDA”) or Congress.  For FDA’s part, the Agency, along with the Centers for Disease Control (“CDC”), has attempted to improve public awareness of the capabilities of current antibiotics, detailing when and how the drugs should be used. (CDC – Get Smart)  Furthermore, the Agency increased labeling requirements for antibiotics, instructing physicians when to prescribe antibiotics – “only to treat infections that are believed to be caused by bacteria” – and encouraging physicians to discuss proper use with their patients.  Finally, the FDA has created guidance documents for pharmaceutical companies “to evaluate how an antibacterial drug works for the treatment of different types of infections.” (FDA – Resistance)

On the legislative side, Congress passed the Generating Antibiotic Incentives Now Act (“GAIN”) in 2012.  The Act requires the FDA within two years of its enactment to create a list of “qualifying pathogens”, which will then be reviewed every five years.  “Qualifying pathogens” are those that the FDA has identified as posing a serious threat to public health.  The antibiotics that treat these qualified pathogens are known as “Qualified Infectious Disease Products” (“QIDP”).  GAIN also creates incentives for QIDP development.  The GAIN Act provides that any QIDP be eligible for fast track designation and receive priority review for marketing approval rather than proceeding through the standard and cumbersome New Drug Approval process.  Once the drug is approved, the Act grants the QIDP developer an additional five years of market exclusivity on top of that already guaranteed by the Hatch-Waxman Amendments, allowing the branded company to recoup more of its losses before generics enter the market.  (FDA – Innovation Act and PEW Heath Report).  As of October 2013, sixteen antibiotics have been designated as QIDP, with two possibly being approved in 2014. (PEW Heath Report)

Incentivizing antibiotic development may be problematic to implement, primarily because of cost.  We are not used to paying for expensive antibiotics.  A standard course for a current brand-name antibiotic costs around $3,000 per patient.  Compared to current cancer treatments that may cost up to $100,000 per patient, even the most expensive antibiotic is relatively cheap. QIDPs, however, will fall into a category of drugs used to treat rare diseases, which tend to cost nearly $200,000 per patient.  Because QIDPs do not have high potential for profits, the U.S. Government has turned to funding initiatives to assist new antibiotic development.

The FDA’s and CDC’s new policies and Congress’s GAIN Act have already made great steps to encourage the industry to invest in antibiotics.  On July 9, 2013, the FDA issued a proposed rule to establish the “qualifying pathogen” list.  The FDA has granted 24 QIDP designations for upcoming antibiotics.  (FDA Reviewing FDASIA)  Despite these efforts, more can still be done.  The Government needs to create more incentives for the industry to develop these drugs alongside guaranteed moneymakers.  While funding initiatives may encourage pharmaceutical companies, the best encouragement is more likely larger Medicare and insurance reimbursements for existing drugs, granting the industry a better opportunity to remake the money spent in development of the more expensive QIDPs.  (Forbes)  Insurance providers, interest groups, and physicians need to be more active in informing their patients of what to expect from the developing drugs: what the drugs can do, what they cannot do, and just how expensive they are going to be.  In the end, if Margaret Chan is incorrect and this is not the end of the antibiotic era, it is certainly the end of the cheap antibiotic era.
