Gleevec, a drug that treats a rare form of leukemia, was approved in 2001 with a list price of $26,400 per year. Since then, its price has steadily increased, reaching over $120,000 per year currently. While the drug has competition now, its price increases were incremental at first and accelerated even before competitors entered the market. The price hikes have helped make Gleevec a top revenue drug for its manufacturer, Novartis, even though it was initially not expected to be a major moneymaker due to the small patient population. However, critics argue there is a lack of meaningful competition in the drug market that would normally drive prices down.
