Vanda Pharmaceuticals Raises Concerns Over FDA's New Guidance on Drug Development
- FDA Guidance Concerns: Vanda Pharmaceuticals expressed serious concerns regarding the FDA's draft guidance released on March 18, 2026, which aims to support New Approach Methodologies (NAMs) but fails to deliver the substantial reforms needed for a shift away from animal testing, potentially impacting drug development efficiency and ethical standards.
- Ethics and Science Balance: While Vanda acknowledges the FDA's commitment to improving human predictivity and ethical standards, the draft guidance does not strike a better balance between regulatory caution and the scientific reforms necessary, which could delay patient access to safer drugs and affect Vanda's leadership in innovative drug development.
- Legal Challenges to Animal Testing: Vanda has a proven track record of advocating for science-driven change, including legal challenges against FDA requirements for prolonged animal studies, such as nine-month dog toxicity tests, highlighting the ethical imperative to minimize animal suffering, particularly in dogs.
- Collaboration and Policy Advocacy: Vanda stands ready to partner with the FDA, HHS, and stakeholders to advance regulatory policies that leverage cutting-edge science, protect patient safety, reduce animal suffering, and align with both ethical and scientific imperatives, aiming to accelerate the drug development process.
