Orphan Drugs Get Special Treatment

Image of lab equipmentYou wouldn’t think that being called an “orphan” is a good thing. But for developers of treatments for rare diseases — including inherited retinal conditions — “orphan” status provides valuable benefits, such as tax incentives, access to special research grants and assistance with clinical trial design. The orphan designation also gives seven years of market exclusivity to the developer of a treatment.

The orphan designation was the result of the Orphan Drug Act of 1983, which facilitates the development of treatments for diseases affecting fewer than 200,000 people in the United States. Congress passed the act because markets are small for rare conditions, and companies are often not motivated to develop therapies for them.

Orphan status is granted by the U.S. Food and Drug Administration. The European Medicines Agency provides similar benefits for rare-disease therapies being developed in Europe.

Most emerging therapies in clinical trials for inherited retinal diseases have received orphan status, including Oxford BioMedica’s gene therapies for Stargardt disease and Usher syndrome type 1B and Advanced Cell Technology’s stem cell treatment for Stargardt disease.

I am always quick to point out the irony that rare diseases aren’t all that rare. As I mentioned in a blog post on Rare Disease Day — February 29, 2102 — there are more than 7,000 rare diseases, and one in 10 Americans is affected by one. Chances are that you or someone you know is affected by a rare disease, and will someday benefit from orphan-designated therapies.

  1. I am always excited when reading about the progress being made for rare diseases, especially retinal diseases. I am from Australia and have a three year old with Leber’s Congenital Amaurosis and there doesn’t seem to be any progress being made in Australia. I am hopeful that there will be a cure in the near future.

  2. An outstanding share! I have just forwarded this
    onto a friend who had been doing a little research on this.
    And he actually ordered me lunch simply because I found it for
    him… lol. So allow me to reword this…. Thank YOU for
    the meal!! But yeah, thanx for spending some time to talk about this topic here on your web page.

  3. Good article. I will be experiencing many of these issues as well..
