There are millions of people that suffer from obscure, unknown, and rare diseases. Together, these people make up a substantial portion of the population, but alone they are not an appealing business venture when it comes to discovering and marketing pharmaceutical treatments. For example there are approximately 8,000 different rare diseases. However, for a disease to be classified as a “rare disease,” it must afflict less than 200,000 people.
This is what we call an
orphan drug (developed specifically to treat a rare medical condition) and
orphan disease ( so rare, obscure, or unknown that the disease does not have any viable treatment.) The economics of drug research, development, and marketing for orphan disease treatment is simply not profitable for the industry because so few are in demand of the product that would be created for each disease.
In comes
The Orphan Drug Act (ODA) of January 1983. The ODA was specifically designed to encourage pharmaceutical companies to develop drugs for those diseases that have a small market. Under the ODA a company that develops an orphan drug for a rare disease may sell it for seven years without any competition. In other words, they will have a monopoly on the drug for seven years. The company may also receive clinical trial incentives through grants to defray the cost of clinical research; tax credits worth up to 50% of the cost of clinical trials; a waiver of the Prescription Drug User Fee Act filing fees, that was worth an estimated 1 million per application in 2008; regulatory assistance; and expedited review processes.
The ODA also removed some of the red tape that held orphan drugs from development. All drugs focus on the pharmacokinetics, dosing, stability, safety and efficacy of a drug. However, the ODA acknowledges that the process for clinical trials of orphan drugs have special factors. For example, it might not be possible to test 1,000 patients for a phase III clinical trial of an orphan drug, as there may not even be that many people affected by the disease.
The ODA success is clear. In the decade before the ODA was enacted, less than ten such products for rare diseases saw the market. From 1983 to 2009, an estimated 2,116 drugs received an orphan drug designation by the Office of Orphan Products Development (OOPD), 353 actually being approved for the market. The Orphan Drug Act of 1983 has clearly helped to improve the quality of life for many afflicted with rare and obscure diseases by making orphan drug research, development and marketing economically feasible and profitable for may companies.
However, there is still one major problem associated with orphan drugs… patient affordability. While the ODA made it fiscally attractive for the companies putting out orphan drugs, that does not mean that these companies are ethically concerned with ensuring patients get the medication at an affordable price. In knowing that they have a monopoly on a drug that is the only treatment option, they know that the patient will pay whatever they set the price at. The ODA incentives already make orphan drugs a profitable venture for pharmaceutical companies. Yet, pharmaceutical companies are not happy with some profit, they want extraordinary profit. The prices of some of these orphan drugs per year are more than most people spend on a home.
Take
Botulism Immune Globulin (BIG) for treatment of infant botulism for example. Botulism Immune Globulin cost 10.6 million dollars to bring from discovery to market. The FDA OOPD contributed $3.7 million of that cost. Yet, Baby-BIG cost $45,300 per infant/per dose.
Copaxone, for relapsing-remitting multiple sclerosis, cost $1,771 per injection. In 2007, Teva Pharmaceuticals made $0.303 billion dollars from the sell of Copaxone.
Humira, for JV idiopathic arthritis cost $1,391 for a month supply. Abbott made $0.462 billion dollars of Humira in 2007. The list goes on and on, but you get the point.
In 1990, Congress tried to amend the ODA to address some of the abuses. The bill would have reviewed the sale record of orphan drugs in the 5th year of marketing, determined if there was still limited marketing value, and if not- it would lose two years of marketing exclusivity. The amendment passed Congress, but was sadly vetoed by President Bush.
The ODA is doing a great service to those with rare and obscure diseases. No one is asking pharmaceutical companies to trade profitability for philanthropy, but there should be some standardized safety net to prevent profit gouging of orphan drugs.
