Animal Exploitation
Since Jan 3, 2022

Syndax Pharmaceuticals is a clinical-stage biopharmaceutical company whose drug development pipeline relies on animal testing. The company’s preclinical research, as documented in scientific publications and SEC filings, involves testing drug candidates in animal models, including a murine renal cell carcinoma model. This activity is a standard, integral part of its business model for advancing oncology treatments toward human clinical trials.

The company is listed by Cruelty Free Investors as a firm that conducts animal testing. As a pharmaceutical developer without marketed products, its research and development operations are fundamentally dependent on animal data to satisfy regulatory requirements for investigational new drug applications.

Animal Testing & Research
Since Jul 28, 2021

Syndax Pharmaceuticals is a clinical-stage biopharmaceutical company whose core business is developing novel cancer therapies. The company’s drug development pipeline, as detailed in its public SEC filings, relies on animal testing as a standard and required component of its preclinical research. The company states that the “completion of extensive preclinical laboratory tests and animal studies” is part of its development process for product candidates like revumenib (Revuforj) and axatilimab (Niktimvo). This testing is conducted to satisfy regulatory requirements for safety and efficacy prior to human clinical trials.

As a pharmaceutical company with no marketed products, Syndax’s entire value proposition is built on advancing drug candidates through the regulatory pathway, which mandates animal data. The company’s research and development activities are therefore intrinsically linked to the commissioning and funding of animal testing.

Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.

This information is provided for educational and transparency purposes only and should not be relied upon as investment advice. Data is drawn from independent watchdogs, NGOs, government registries, and Ethical Capital's ongoing research — see Research Sources for the full list.
