History[edit | edit source]
Gilead Sciences was founded in 1987 by Michael L. Riordan, a medical doctor. The company was originally named Oligogen, Inc. and was later renamed Gilead Sciences. Gilead's first product, Vistide (cidofovir), was approved by the U.S. Food and Drug Administration (FDA) in 1996 for the treatment of cytomegalovirus (CMV) retinitis in patients with AIDS.

Gilead Sciences has developed several notable drugs, including:
- Atripla - a combination drug for the treatment of HIV/AIDS.
- Truvada - used for both treatment and pre-exposure prophylaxis (PrEP) of HIV.
- Harvoni - a combination drug for the treatment of hepatitis C.
- Sovaldi - used for the treatment of hepatitis C.
- Remdesivir - an antiviral drug that has been used in the treatment of COVID-19.
Research and Development[edit | edit source]
Gilead Sciences invests heavily in research and development (R&D) to discover and develop new therapies. The company has a strong focus on antiviral therapies but also explores treatments for other conditions, including oncology and inflammatory diseases.
Acquisitions[edit | edit source]
