Some Things You May Not Know About Generic Drugs

The rising cost of healthcare, increasing drug prices and the restrictive nature of the formularies of many insurers and third party payers is forcing a growing number of Americans to rely almost exclusively on generic prescription drugs. The trouble is that most Americans know very little about generic drugs; mainly because big pharma has done its best to minimize the discussion about generics and continues to portray generic manufacturers as less than reputable purveyors of prescription drugs. Because of this, I think that American ought to begin to understand an industry that increasingly will play a major role in the US healthcare system. So here goes:

  1. According to IMS Health, generic drugs accounted for 70 percent of the 2.9 billion prescriptions filled in the US in 2009
  2. Generic drugs accounted for only 15 percent of almost $300 billion spent on prescription drugs last year in the US
  3. Since 2003, the US Food and Drug Administration (FDA) received 800 new generic drugs applications; up from an average of 330 applications per year in the last decade
  4. Five years ago, it took FDA regulators an average of 16.3 months to review and approve generic new drug applications; by 2009 the average time to approval had ballooned to 27.7 months
  5. There is a backlog of nearly 2,000 pending generic new drug applications, almost double the backlog at the agency in 2005
  6. FDA’s division of generics had a budget of only $41 million in 2009; its budget for 2010 is $511 million
  7. Unlike branded pharmaceuticals, companies seeking regulatory approval for new generic drugs don’t pay user fees
  8. According to FDA Commissioner Dr. Margaret Hamburg generics saved American consumers almost $750 billion over the last decade.

Based on these facts, it is evident that FDA is seriously under funded, under staffed and overwhelmed by the spike of new generic drug applications in recent years. Interestingly, President Obama’s proposed 2010 budget included $38 million in user fees from generic manufacturers to process new drug applications. Not surprisingly, generic manufacturers are not willing to pay these fees unless the approval time for their products is drastically shortened. To that end, FDA is hiring 50 more reviewers and hopes that personnel increases will eliminate the generic drug application backlog by 2012. 

Dr. Hamburg is also looking to streamline some aspects of the generic drug application review process. For example, she proposed giving higher priority to generic drugs applications for branded drugs whose patent expiry is imminent as compared with applications for drugs that have several more years of patent protection remaining.

Nevertheless, the bottom line is that the agency needs a much larger budget and staff to keep up with the ongoing torrent of new generic drug application. With this in mind, the agency ought to consider reallocating existing resources—rather than wait for budget increases in these financially uncertain times—to process new generic drug applications in a timely fashion. This may be possible because of the annual number of drug applications for new, branded prescription drugs has steadily been decreasing for the past five years.

More Regulatory Woes for New Antibiotic

Theravance Inc. announced Thursday US Food and Drug Administration (FDA) regulators are not satisfied with new data on its infection drug candidate telavancin (Vibativ), and indicated that further clinical studies may be required to win marketing approval.

Approval of Vibativ has been held up for three years, as the Food and Drug Administration asked the company for more data about the drug, and about studies Theravance has conducted in support of its application to the FDA. Theravance said Thursday the FDA told it the data so far is not enough to prove Vibativ works.

The agency will not begin a formal review of the drug until it says it is satisfied with the data.

Vibativ, or telavancin, is an injection intended to treat complicated or drug-resistant infections like methicillin-resistant Staphylococcus aureus (MRSA). Theravance submitted an NDA to FDA for review in December 2006.

According to Theravance, the FDA did not say Theravance would have to run a new clinical trial to gain approval, but it suggested a design for such a study. Company representative said that they do not know what the FDA wants and said the agency did not provide any suggestions about the goals of the proposed study, how many patients should be included, or even how many studies might be required ( I guess it may be time for a meeting to discuss these issues?).

In response to the FDA’s previous requests for more data on telavancin, Theravance said it combined data from two late stage trials of Vibativ, with the goal of making the data more comparable. It said the FDA told it that the data is equal to only one study. Two late-stage trials are often required to win approval.

Theravance said it has tested Vibativ on about 1,500 patients and said its studies are the largest that have been submitted in support of a new drug of its type.

Regulatory concerns about Vibativ include a risk of birth defects when it is used in pregnant women, manufacturing issues, and questions about data comparing the drug to vancomycin, which is the most powerful antibiotic currently on the market.

While getting new antibiotics are the market are important, clinical studies must be carefully designed with appropriate endpoint to address potential safety and efficacy issues. Although Theravance believes that it has done that, the agency, as always, will be the final arbiter of a decision on telavancin.

Until next time...

The FDA New Drug Approval Conundrum Revealed

FDA approvals of biopharmaceutical products have decreased in recent years. This includes recombinant proteins and monoclonal antibodies and cancer therapeutics. In the decade from 1996-2005, an average of 16.6 new drugs were approved each year. In marked contrast, there were only 11 and 12 new medications approved in 2006 and 2007, respectively.

Last year was an unusually unproductive year for the pharmaceutical and biotechnology industry. The combined sales for products approved in 2007 are projected to be less than $1.0 billion dollars–the benchmark for drugs that receives blockbuster status. Further, most or the approved drugs were similar to ones that were previously approved (so called “me too” drugs) and none will significantly improve healthcare for large numbers of patients.  Finally, only two recombinant protein drugs were approved in 2007–a level more representative of the 1980s.

Most analysts agree that it is unclear why FDA approval of new drugs has decreased over the past few years and who, if anybody (FDA and/or industry), deserves the blame for the approval drop-off. Regulatory filings for a number of new products are either expected or currently pending. To that end, it is likely that there will be more new approvals in 2008 and 2009 as compared with previous years. To learn more about the drug approval conundrum please read this article recently written by Ronald A Radar.

The rate of new approvals must increase in order for the biopharmaceutical and pharmaceutical industries to remain economically healthy and viable. Industry and the FDA must work more closely with one another to continue to insure that the American public has ready access to innovative, safe and efficacious, new biopharmaceutical and pharmaceutical products.
