Tenax Therapeutics, Inc.

Tenax Therapeutics, Inc. is a pharmaceutical company whose drug development pipeline relies on animal testing. The company’s lead investigational drug, levosimendan, has been studied in animal models as part of its development process. Tenax is listed by Cruelty Free Investors among companies that exploit animals through testing.

The company’s business is centered on developing cardiovascular and pulmonary therapies, an area of medical research that historically and currently depends on animal data for preclinical safety and efficacy studies. While specific numbers of animals used are not disclosed in public filings, the nature of its clinical-stage pipeline implies ongoing animal testing is integral to its research and regulatory submission strategy. There is no public commitment from Tenax to adopt non-animal testing methods or to phase out animal use in its development programs.
