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

Prelude Therapeutics is a clinical-stage biotechnology company whose business model is fundamentally dependent on animal testing. The company’s drug discovery and development pipeline requires extensive preclinical testing in animals to assess the safety and efficacy of its therapeutic candidates before they can proceed to human trials. This reliance on animal models is a core, unavoidable component of its research and development activities.

Cruelty Free Investors flags the company due to its engagement in this practice. The use of animals in biomedical research remains a subject of significant public concern and regulatory scrutiny, driven by ethical considerations regarding animal welfare and scientific debates about the predictive value of animal models for human outcomes.

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.
