Abstract
Pharmacometrics (PMX) models form the foundation of model-informed precision dosing (MIPD), underpinning and supporting clinical decision-making. However, PMX models are often complex, requiring significant computational effort for numerical solutions, with covariate selection typically being the most time-intensive step. Integrating PMX with advanced data science tools, such as artificial intelligence (AI) and machine learning (ML), could provide efficient methods for processing large, heterogeneous datasets, enhancing PMX models by supplementing small sample sizes and expanding parameter inference. These tools would have strong predictive and learning capabilities to aid model development and improvement, though they provide less biological interpretability than PMX. AI and ML have gained increasing popularity across various disciplines in the last decade, but their application in MIPD remains in its early stages, holding promise for the future.
Precision Dosing and Reinforcement Learning
Precision dosing, which customizes drug doses to optimize therapeutic outcomes and minimize risks, is crucial for medications with narrow therapeutic windows and severe side effects. Adaptive dosing strategies build on this by adjusting doses over time based on changing patient conditions. Reinforcement learning (RL) aligns well with this approach, as it mirrors the sequential decision-making process used by clinicians to adjust treatments according to patient responses. This webinar explores the potential of integrating RL with population pharmacokinetic/pharmacodynamic (PK/PD) models to create precision dosing algorithms. It reviews key studies where PK/PD models were embedded within RL systems to predict the impact of dosing decisions. Additionally, It discusses how to frame precision dosing problems within the RL framework, including system states, actions, and rewards, and how PK/PD models can enhance RL techniques.
AI-Driven De Novo Antibody Design
The rapid evolution of artificial intelligence has opened new frontiers in biologics discovery, particularly in the design of therapeutic antibodies targeting previously intractable molecules. Antibodies against GPCRs and ion channels—critical yet historically difficult-to-drug targets—are increasingly recognized as pivotal in addressing a wide range of diseases. Despite significant advancements, challenges remain in designing highly specific and functional antibodies with favorable developability profiles.
This seminar provides an overview of AI-driven approaches to de novo antibody discovery, emphasizing the integration of computational tools and experimental workflows. By employing generative models and
advanced clustering techniques, it is now possible to predict high-affinity binders with exceptional precision and efficiency. Examples will be drawn from recent successes in rapidly generating therapeutic candidates with nanomolar affinities and high functional diversity. In addition, the seminar will explore the potential of these methodologies to address broader therapeutic challenges, such as inflammation, highlighting their implications for advancing immunological research and clinical practice. The session concludes with a discussion on the future trajectory of AI applications in biologics, including the potential for accelerating innovation in antibody therapeutics.
