Updated February 8, 2026 at 3:34 PM UTC

The Reducing Animal Testing Act would let drug manufacturers and sponsors use non‑animal testing methods when evaluating the safety and effectiveness of biological products. By expanding what kinds of studies can be used for toxicity assessments, the bill aims to cut back on the use of animals in drug development.

Key Provisions

  • Amends the Public Health Service Act to add language allowing toxicity assessments to rely on alternative (non‑animal) studies described elsewhere in the law.
  • Explicitly permits manufacturers and sponsors to use these alternative testing methods instead of animal testing for biological products.
