Advancing Medicine: A Shift Towards Human-Based Research

Federal policies are poised for updates that could considerably accelerate medical advancements while reducing reliance on animal testing. Experts advocate for increased investment in technological innovations for human health research and regulatory testing, recognizing the limitations of animal models and the potential of new approach methodologies (NAMs).This change aims to improve research efficiency, increase the success rate of drug development, and ultimately, deliver safer and more effective treatments to patients.

The Limitations of Animal Research

Historically,animal models have been a cornerstone of biomedical research.However, research increasingly demonstrates that results obtained in animals often fail to translate to humans. This is due to fundamental biological differences in anatomy, physiology, disease manifestation, and lifespan [[1]]. These differences mean that a treatment seemingly effective in animals has a surprisingly low probability of success in human clinical trials-approximately nine out of ten drugs that show promise in animal studies ultimately fail in humans . This not only leads to wasted research funds but also poses risks to patients participating in early clinical trials.

The Rise of Human-Based Research Methods

Fortunately, advancements in science have paved the way for more reliable and predictive human-based research methods. These new approach methodologies (NAMs) leverage human cells, tissues, organs-on-chips, advanced computing, and artificial intelligence to model human biology and disease with greater accuracy.NAMs have the potential to greatly improve the efficiency of the research and regulatory process, and further, reduce the number of animals used in research.

Policy Recommendations to Accelerate the Transition

To facilitate a smooth and effective transition to human-based research, the following policy mechanisms are being proposed:

Funding and Economic Incentives

• Strengthen the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs to specifically support the development and validation of NAMs.
• Encourage federal agencies to utilize Other Transaction Agreements (OTAs) and cooperative agreements-along with milestone-based funding-to support emerging human-relevant technologies.
• Promote partnerships between federal agencies and small and medium-sized businesses for qualification and research.
• Increase funding for novel and unconventional research proposals.
• reallocate funds away from animal-based research projects and infrastructure towards human-based methodologies.

Infrastructure and Institutional Transformation

• Transform animal research facilities, including National Primate Research Centers, into modern hubs for human-based methods.
• Prioritize the development of dedicated human-based research centers at academic institutions.
• Expand public-private partnerships focused on translational science infrastructure across agencies.
• Create funding opportunities for infrastructure and training at new academic institutions.
• Establish research institutes concentrating on areas where animal experimentation has previously yielded limited clinical success.
• Facilitate interdisciplinary collaboration to enhance the development and implementation of human-based methods.
• Invest in AI-ready, human-relevant data infrastructure, accessible standards, and public data access.
• Support integrated AI and NAM pipelines to improve translation and minimize animal use.

Policy and Regulation Reform

• Update existing statutes, regulations, and policies to expedite the phase-out of animal use.
• Prioritize the replacement of primate experiments with human-based methods.
• Prohibit the use of federal funds for tests like the forced swim test and tail suspension test.
• Address potential biases in peer review processes that favor animal use through training and diversification of review panels.
• Develop evaluation and validation frameworks specifically tailored for AI systems.

key Takeaways

• Animal research frequently fails to accurately predict human responses due to species differences.
• Human-based research methods, notably NAMs, offer more reliable and predictive models.
• Strategic policy changes are needed to accelerate the transition to human-based research.
• Increased funding, infrastructure development, and regulatory reform are crucial for success.

By embracing these changes, the federal goverment has the chance to accelerate medical innovation, reduce research waste, and improve the lives of patients, all while upholding ethical considerations regarding animal welfare. A future focused on human-relevant research promises a more efficient and effective path to medical breakthroughs.
