Abstract:
The common and persistent failures to translate promising preclinical drug candidates into clinical success highlight the limited effectiveness of disease models currently used in drug discovery. An apparent reluctance to explore and adopt alternative cell- and tissue-based model systems, coupled with a detachment from clinical practice during assay validation, contributes to ineffective translational research. To help address these issues and stimulate debate, here we propose a set of principles to facilitate the definition and development of disease-relevant assays, and we discuss new opportunities for exploiting the latest advances in cell-based assay technologies in drug discovery, including induced pluripotent stem cells, three-dimensional (3D) co-culture and organ-on-a-chip systems, complemented by advances in single-cell imaging and gene editing technologies. Funding to support precompetitive, multidisciplinary collaborations to develop novel preclinical models and cell-based screening technologies could have a key role in improving their clinical relevance, and ultimately increase clinical success rates.
Insights
Drug discovery faces challenges due to ineffective preclinical models. Adopting advanced cell-based systems and multidisciplinary collaboration can improve clinical translation success rates for new therapies.
Area of Science:
- Drug discovery and development
- Translational medicine
- Preclinical research
Background:
- Current preclinical drug discovery models often fail to predict clinical success, leading to high attrition rates.
- A lack of adoption of advanced cell-based models and insufficient clinical relevance in assay validation hinder translational research.
- Ineffective disease models contribute significantly to the persistent failures in translating preclinical drug candidates to clinical success.
Approach:
- Propose principles for defining and developing disease-relevant assays to improve preclinical model effectiveness.
- Explore novel cell-based assay technologies, including induced pluripotent stem cells (iPSCs), 3D co-cultures, and organ-on-a-chip systems.
- Leverage advances in single-cell imaging and gene editing technologies to enhance preclinical models and screening.
Key Points:
- Development of disease-relevant assays requires clear principles and validation against clinical practice.
- Emerging technologies like iPSCs, 3D co-cultures, and organ-on-a-chip systems offer improved physiological relevance.
- Integrating advanced imaging and gene editing can refine cell-based screening and model development.
Conclusions:
- Implementing proposed principles and adopting advanced cell-based technologies can enhance the clinical relevance of preclinical models.
- Multidisciplinary collaborations are crucial for developing and validating novel preclinical models and screening technologies.
- Increased investment in precompetitive research for advanced preclinical models is essential to improve drug discovery success rates.
