Lexicon Pharmaceuticals, Inc.

Lexicon Pharmaceuticals is a biopharmaceutical company whose drug development pipeline requires animal testing for preclinical safety and efficacy studies. As a developer of new molecular entities targeting the central nervous system and other areas, the company's research operations involve the use of laboratory animals, including rodents and non-human primates, to assess abuse liability, toxicity, and therapeutic potential.

The company has engaged contract research organizations, such as Covance, which have faced public allegations regarding the treatment of primates in testing facilities. While specific, recent violations directly attributable to Lexicon's own facilities are not documented in the provided evidence, the company's business model is inherently dependent on animal-based research to advance its pharmaceutical candidates to clinical trials. This places its operations within the scope of commercial animal exploitation for research purposes.
