Abstract
Orphan drug products (e.g. drugs and biologics) in the United States are those that treat
people with rare chronic diseases, often cancer or metabolic disease. The rare disease condition
being treated by these orphan drugs must serve a patient population of less than 200,000 people in
the U.S. in order to earn the orphan drug product title. Just as the disease conditions are seen as
“orphans,” so, we assert is the thermochemical understanding of the drugs themselves in terms of
the chemical structures that define those drugs. This article illustrates this orphan thermochemical
status for a recent series of orphan drugs.
Keywords:
