Gilead’s research and development program identifies and evaluates investigational compounds that show potential to advance the treatment of life-threatening diseases in areas of unmet medical need. Safety and efficacy of the following compounds have not been established.

Gilead has helped transform HIV infection from a fatal and debilitating disease into a chronic, manageable condition. Yet new options are needed to improve treatment and care over the course of a lifetime for diverse populations living with HIV around the world. With two million new infections each year, additional prevention options are also needed. And ultimately, a cure is needed to bring an end to the HIV epidemic.

Gilead is committed to the continued discovery and development of HIV therapies for all individuals who live with the disease, regardless of treatment status or age. Our research is focused on the three paradigms: prevention, treatment and cure.

Despite important scientific progress, cancer remains a leading cause of death worldwide. In both blood cancers and solid tumors, there is an urgent need for new treatments that offer longer remissions, improved survival rates and fewer side effects.

Gilead is exploring novel therapeutics, including combinations of investigational agents, for a range of cancers, with a goal of providing effective new treatment options with favorable safety profiles.
