Gleevec is one of the revolutionary drugs that has transformed some blood cancers into chronic illnesses rather than death sentences. According to one study cited in Science Life, 5-year survival rates for patients with chronic myelogenous leukemia was 30% before Gleevec. After Gleevec, 89% of patients hit that target.

The story of Gleevec's development has been told, in detail, many times. We won't go into it here (if you're interested in the details, check out this article from Nature.. What we will tell you is that the scientists involved--including researchers from Memorial Sloan-Kettering Cancer Center, Oregon Health & Science University, as well as Novartis ($NVS)--won the prestigious Lasker Award for their achievement.

Right now, Gleevec, which is sold as Glivec in some countries, is in the middle of a big intellectual property battle in India.

It filed an appeal recently, but that's still pending.
