This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.

Animal Testing & Research
Since Mar 12, 2026

Cyclerion Therapeutics is a clinical-stage biopharmaceutical company whose drug development pipeline relies on animal testing as a standard, required component of the regulatory process. The company’s preclinical research and clinical trial applications for central nervous system disorders involve animal models to assess drug safety and efficacy. This testing is a fundamental and non-negotiable element of bringing its pharmaceutical candidates to market, placing the company within the scope of commercial animal exploitation for research purposes.

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.
