In preclinical drug development, 2D pathological assessment and routine pharmacokinetic analysis are mainstream. However, these methods alone face challenges in fully demonstrating the detailed mechanism of action (MoA) of a drug or its accessibility to target tissues. This article will explain what advanced analytical and imaging technologies exist and the criteria for selecting them.
In non-clinical studies, standard evaluation systems alone may be insufficient to capture the "true pharmacological effect." 2D pathology relies on fragmented cross-sectional information of tissues, thereforeUnable to determine if the drug adequately reaches the target in terms of surface area or three-dimensionality, potentially leading to false negatives.There are concerns that dramatic changes occurring in rare cell populations may be masked by average data across the entire organization. Furthermore, traditional sampling intervals present challenges in capturing the discontinuity of dynamics, such as instantaneous in vivo responses or local accumulation.
To improve clinical predictability (extrapolation),Cutting-edge technologies that reproduce human-specific reactions in the preclinical stage are important.This allows us to reduce the risk of unexpected dropouts in clinical trials due to animal species differences by utilizing humanized mice and PXB mice (humanized liver models). Ultra-high sensitivity measurement technologies such as Simoa can detect early changes in extremely low levels of biomarkers, similar to human clinical settings. In addition, by directly reflecting image and omics data obtained in non-clinical studies into the clinical protocol design,Enhance translational science and improve the quality of bridge researchWill make it happen.
To accelerate licensing out and fundraising, building compelling evidence is essential.In addition to graphs and tables, "visual impact" such as 3D videos and high-resolution imaging is also important.This intuitively helps investors and partners understand and speeds up decision-making. Quantitative data that ensures objectivity, such as AI-driven automatic scoring, demonstrates high reliability in due diligence and works in your favor. By including original mechanism proofs from advanced analysis in addition to standard data, it can also lead to an increase in the valuation of the pipeline.
