What's the difference between a disease affecting 300 and 300,000,000?

To us, nothing.

There are diseases so rare that they only affect a few thousand, or even a few hundred, people. At Sigma-Tau Pharmaceuticals, Inc., our mission is to help ensure these people are not left untreated. We are dedicated to providing new therapies and new hope for patients with rare diseases.

Under the visionary leadership of our founder, Dr. Claudio Cavazza, every one of us shares an unwavering commitment to develop novel products and therapies for rare diseases and small numbers of patients. As you navigate through this site, you'll see this commitment reflected in our people, our research, our patient support, and our pipeline.
