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.
Curis, Inc. is a biotechnology company whose core business model involves developing cancer therapeutics. The company's drug development pipeline necessitates extensive animal testing as part of preclinical research and regulatory compliance. In its public disclosures, Curis explicitly acknowledges conducting long-term preclinical animal tests, including studies for reproductive adverse events and carcinogenicity, which are standard requirements for FDA approval of new drugs.
The evidence gathered indicates that animal testing is an integral and unavoidable component of Curis's operations. While the specific scale and numbers of animals used are not detailed in the available public filings, the nature of its business in oncology drug development implies a reliance on in vivo models to assess drug efficacy and safety. This places the company's activities under the general animal_exploitation exclusion category, as the testing is conducted for commercial development purposes and is not covered by a more specific child code.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
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.
