Rare Disease Day: FDA to Offer Orphan Drug Development Workshop

A rare or orphan disease is defined in the US as one that affects fewer than 200,000 at any given time. It is estimated that there are 6000 to 8000 rare diseases in the world today. Because the number of patients afflicted with orphan diseases is so small, drug companies have historically been reluctant to invest money to discover and develop new treatments for them. The dearth of treatments for rare diseases induced Congress to pass the Orphan Drug Act in 1983 which provided market exclusivity, tax breaks and incentives and regulatory help for companies to development new drugs for orphan disease indications.

While many current blockbuster drugs including recombinant human insulin, growth hormone and erythropoietin originally garnered regulatory approval after receiving orphan status in the late 1980s, most big pharma and biotechnology companies (except Genzyme) largely abandoned orphan drug development until recently. The renewed interest in orphan drug development has been primarily driven by the demise of big pharma’s blockbuster business model that began in the early 2000s. The search for new, non-blockbuster drugs and fresh markets is what induced Pfizer, the world’s largest pharmaceutical company, to recently inked a multimillion dollar deal with Protalix Biotherapeutics, a small biopharmaceutical company developing a new treatment for Gaucher disease—an orphan indication.

Because of renewed interest and the ever increasing need for new orphan drugs, the FDA’s Office of Orphan Products Development is offering an Orphan Drug Designation Workshop that will provide a unique opportunity for all potential drug sponsors—including biotechnology companies, pharmaceutical firms and academic institutions—to learn about the application process for orphan drug designation.

The National Organization for Rare Disorders (NORD) is a co-sponsor of the workshops, which will take place on February 25-26 at Keck Graduate Institute and August 3-4 at the University of Minnesota.

Participants are encouraged to bring specific product proposals for at least one candidate orphan drug that holds promise for the treatment of a rare disease. A significant portion of the workshop will be dedicated to preparing applications, including one-on-one guidance sessions with FDA staff members. FDA will keep product and disease information confidential.

Final applications can be submitted to the FDA at the close of each workshop. For information or to register:

Finally, February 28th is Rare Disease Day. The event is sponsored by the EURODIS a European advocacy group that promotes awareness and research for rare diseases. NORD and Discovery Health are also sponsoring the day.

Until next time....

Not All Generics Are Created Equal

The generic drug industry didn’t exist until the passage of the Drug Price Competition and Patent Term Restoration Act of 1984 (Hatch-Waxman Amendments). This piece of legislation, better known in the pharmaceutical industry as the Hatch-Waxman Act, was proposed and adopted by the US Congress because of the escalating costs of brand name drugs manufactured by large pharmaceutical companies (sound familiar?). The act provided the US Food and Drug Administration (FDA) with a regulatory pathway to approve and bring to market “generic” versions of branded drugs that lost patent protection. During the debate over the amendment, and for many years thereafter, branded pharmaceutical manufacturers tried to stifle the growth of the generic drug industry by suggesting that generic versions of their branded medications were unreliable and unsafe. This tactic was partly responsible for the stinted growth of the generic pharmaceutical industry until the mid 1990s when the price of branded pharmaceutical drugs began to skyrocket and insurance companies began to realize that something had to be done to manage rising drug reimbursement costs. To that end, insurers and third party payors began requiring patients to use generics (when available) instead of branded products to cap rising prescription drug costs. Because of this, the generic industry has grown by leaps and bound over the past decade and now threatens the stability of the branded pharmaceutical industry! 

Unfortunately, while increased generic drug use may be good for generic drug manufacturers and insurance companies, it isn’t always in the best interests of patients who use prescription medications. For example, there are a growing number of stories and complaints from patients who were forced to switch from a brand name drug to a generic one and had side effects, or found that their symptoms returned or may have been worse than before. In fact, this happened to my mother who was switched from a brand name pain reliever that worked to a generic version that no longer controlled her symptoms and induced some untoward side effects. Scientifically, there ought to be little difference in the efficacy, safety or tolerability profiles of a branded drug and its generic equivalent. This is because both medications contain the same active pharmaceutical ingredient. However, differences in the formulation of the branded and generic versions of the drugs may be responsible for reduced efficacy or safety and tolerability issues.

While clinical studies conducted by the insurance industry suggest there are no safety or tolerability differences between brand name and generic drugs and the American Medical Association’s assertion that, as a whole, generic drugs do work as well as branded drug, there is some evidence to suggest that some generic drugs may not be interchangeable or substitutable for certain branded medications. This appears to be the case for certain drugs that are used to treat neurological conditions and mental health diseases like seizures, depression and bipolar disease. Lesley Alderman, in an article she wrote in today’s New York Time business sections provides excellent examples of this.   

The problems with some generic drugs may arise as a result of the approval process for this class of drugs. According to provisions outlined in the Hatch Waxman Act which stipulate that a generic version must have the same active ingredient, strength and dosage form as the brand name drug or reference product. The generic version must also be demonstrated to be “bioequivalent” to the brand name drug. This means that the generic product must be shown to reach blood levels (drug concentration) that are very similar to the brand name product. This is usually determined by administering the generic and brand name drugs to a relatively small number (24 to 36) of healthy human volunteers. Generally speaking, once bioequivalence is established it paves the way for regulatory approval of the product. Typically, once approved, many generics receive what is known as an AB rating. Generics that are AB-rated can freely be substituted (by a licensed pharmacist) for a brand name product even though the physician may have written the prescription for the branded product.

In the past, patients were usually given a choice between a generic and a brand name drug —a decision that was largely based on the percentage of the cost of drug that would be covered by insurance. These days, patients no longer have a choice and are generally forced to use generic drugs rather than brand name products based on formulary lists compiled by insurance companies. While I am not practically or philosophically opposed to using generic drugs, there is a growing body of evidence which suggests that not all patients respond the same way to branded and for that matter generic drugs. Therefore, I contend that allowances ought to be made for these differences and patients who don’t respond to (or experience side effects) after taking generics shouldn't’t be denied access to the branded product that, in most cases, was originally prescribed by that patient’s physician. It is one thing to cut costs; it is another to increase a patients suffering or anxiety. If you are concerned about switching from a branded medication to a generic, please read this for some helpful tips and guidance.

Until next time...

The National Institutes of Health to Aid Orphan Drug Development

The National Institutes of Health (NIH) announced on Wednesday that it was creating a new program aimed at “finding treatments for some of the 6,800 rare diseases that collectively affect about 25 million Americans.” 

According to NIH officials, the NIH would work with researchers and patient advocacy groups to identify new molecular entities (NMEs) that represent potential treatments for rare disorders. Once identified, NMEs will be turned over to private companies for further development. Information about molecules that failed to make the cut for further development will be published in scientific and medical journals. The NIH stressed that the goal of the program is to work with the drug industry not compete with it to develop new treatments.

Because many rare diseases only affect a few hundred or a few thousand people, there are little financial incentives or profit motives for companies to develop treatments for them. To stimulate drug development for rare diseases, the US Congress passed The Orphan Drug Act (1983) that offers companies that develop drugs for diseases affecting fewer than 200,000 people tax incentives, financial support for clinical development and seven years of US market exclusivity, i.e. the company can sell the product without competition for seven years. Since its passage, the Orphan Drug Act has been a boon to many biotechnology companies, most notably Genzyme, a profitable biotechnology company whose business model is built almost exclusively on orphan drug development.

NIH’s entry into the orphan drug development arena ought to help speed discovery and development of potential new treatments for orphan indications. It will undoubtedly help to reduce some of the cost, time and risks typically associated will corporate drug discovery. Industry experts suggest that drug discovery can sometimes cost well over $10.0 million and take between two to four years to complete. However, the program is starting with only $24 million this year and is expected to receive the same level of funding each year until 2013. While this may limit the overall effectiveness of the program, it will likely bring government and the drug industry closer to forge new relationships with the common goal of discovering much needed new treatment for orphan indications.

Until next time...

The Real Problem at FDA

I spent the entire morning reading various articles, blog posts and comments about what is wrong with the US Food and Drug Administration (FDA). Not surprisingly, phrases like “drug lag”, the large size and costs of clinical trials, political and corporate influence, reduced numbers of NME approvals etc appeared ad nauseum. These are the same old, tired complaints with the agency that have been bandied about for the past 10 years or so. 

In my opinion, the bottom line is this: the agency is egregiously under staffed and under funded despite the fact that companies pay steep user fees for regulatory reviews. I can understand why corporate America is dissatisfied with the service that it receives from FDA. It is natural to expect good customer service after paying large sums of money to a service provider.  However, it is important to note, that the words “customer service” don’t appear any where in the Food, Drug and Cosmetic Act of 1938 (although it can possibly be implied fromPDUFA in 1992 and FDAMA in 1997).  Nevertheless, what is mentioned in the FD&C is SAFE and EFFICACIOUS pharmaceuticals, biologics and medical devices. Put simply, safe and efficacious products, not customer service, is REAL the mission of FDA.  With this in mind, the agency is legally required to do everything in its power to provide Americans with carefully scrutinized and safe medical devices, pharmaceutical and biotechnology products.

If we Americans want FDA to accomplish its REAL mission, then the agency must be sufficiently funded, adequately staffed and have strong, non-partisan leadership. Unless this occurs, FDA will continue to struggle and remain dysfunctional well into the 21st century.

Until next time…
