Abstract:
While great interest in health effects of natural product (NP) including dietary supplements and foods persists, promising preclinical NP research is not consistently translating into actionable clinical trial (CT) outcomes. Generally considered the gold standard for assessing safety and efficacy, CTs, especially phase III CTs, are costly and require rigorous planning to optimize the value of the information obtained. More effective bridging from NP research to CT was the goal of a September, 2018 transdisciplinary workshop. Participants emphasized that replicability and likelihood of successful translation depend on rigor in experimental design, interpretation, and reporting across the continuum of NP research. Discussions spanned good practices for NP characterization and quality control; use and interpretation of models (computational through in vivo) with strong clinical predictive validity; controls for experimental artefacts, especially for in vitro interrogation of bioactivity and mechanisms of action; rigorous assessment and interpretation of prior research; transparency in all reporting; and prioritization of research questions. Natural product clinical trials prioritized based on rigorous, convergent supporting data and current public health needs are most likely to be informative and ultimately affect public health. Thoughtful, coordinated implementation of these practices should enhance the knowledge gained from future NP research.
Insights
Translating natural product (NP) research into clinical trials (CTs) requires rigorous methodology. Implementing best practices in NP characterization, experimental design, and data reporting enhances the reliability and public health impact of findings.
Area of Science:
- Integrative biology
- Translational science
- Natural product research
Background:
- Significant interest exists in the health effects of natural products (NPs), including dietary supplements and foods.
- However, promising preclinical NP research often fails to translate into successful clinical trial (CT) outcomes.
- Clinical trials, particularly phase III, are expensive and demand meticulous planning for optimal data acquisition.
Purpose of the Study:
- To enhance the translation of natural product research into actionable clinical trial outcomes.
- To identify and promote best practices across the continuum of natural product research and clinical application.
- To foster a more effective bridge between preclinical NP studies and clinical trial design and execution.
Main Methods:
- Convened a transdisciplinary workshop in September 2018 focused on improving NP research to CT translation.
- Facilitated discussions on key areas including NP characterization, quality control, and model system validity.
- Emphasized the importance of rigorous experimental design, interpretation, reporting, and transparency.
Main Results:
- Replicability and successful translation are contingent upon rigor throughout the NP research process.
- Key practices include robust NP characterization, validated predictive models, and control of experimental artifacts.
- Prioritizing research questions based on convergent data and public health needs is crucial.
Conclusions:
- Implementing standardized rigorous practices in NP research, from characterization to reporting, is essential for successful translation to clinical trials.
- Coordinated implementation of these best practices will improve the knowledge gained from future NP research.
- This approach aims to enhance the impact of natural product research on public health.
