Gilead Sciences, Inc.

Gilead Sciences is a global biopharmaceutical company whose core business of developing antiviral and oncology drugs requires animal testing for regulatory compliance and product development. The company’s published Animal Use and Welfare Policy explicitly states that animal research is conducted by Gilead and its research partners to support the development of its therapeutic products. As a standard practice in the pharmaceutical industry, this testing is a non-negotiable component of the regulatory pathway for drug approvals from agencies like the U.S. Food and Drug Administration.

The company’s pipeline and portfolio, including therapies for HIV, hepatitis, and cancer, are developed under this model. While Gilead outlines ethical standards and welfare commitments in its policy, the fundamental business activity of bringing new pharmaceuticals to market remains contingent on animal-based research and safety testing.
