Phio Pharmaceuticals Corp. is screened out under 2 exclusion reasons spanning 1 issue category.

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. It is a statement of values.

Animal Exploitation
Since Jan 3, 2022

Phio Pharmaceuticals Corp. develops and commercializes self-delivering RNAi therapeutics designed to stimulate the immune system to fight cancer. The company’s core technology platform and pipeline candidates are based on biological research that requires animal testing for preclinical development and regulatory approval. As a biotechnology firm advancing novel immuno-oncology treatments, its research and development activities inherently involve the commercial exploitation of animals in laboratory settings.

Animal Testing & Research
Since Jul 28, 2021

Phio Pharmaceuticals Corp. is a clinical-stage biotechnology company developing cancer immunotherapies based on its proprietary INTASYL™ RNAi technology. As a pharmaceutical company advancing novel drug candidates through preclinical and clinical development, its research pipeline inherently requires animal testing to satisfy regulatory safety and efficacy requirements. The company’s published research, including studies cited in its SEC filings, explicitly references conducting animal studies to build data for its investigational compounds, such as PH-804. This reliance on animal models is a standard, mandated component of the drug development process for entities seeking FDA approval for new therapeutics.

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.
