DOT Quantitative Systems Pharmacology 


The pharmaceutical industry has been frustrated by the high failure rates of drug development programs, which suggest that the decision making process on various stages of the programs can benefit from some enhancement. One of the approaches rapidly gaining credibility, and showing good promise for informing better decision making is Quantitative Systems Pharmacology (QSP). Cambridge Healthtech Institute will be holding its Inaugural Quantitative Systems Pharmacology conference as part of Discovery on Target with the goal of bringing together experts in QSP and researchers who may be interested in using this methodology. The conference is designed as a knowledge and opinion exchange forum, and will be focusing on strategy and implementation of QSP from early discovery all the way to early clinical development.

APPLICATIONS OF QSP TO DRUG DISCOVERY AND DEVELOPMENT

3:25 Chairperson’s Opening Remarks

Arijit Chakravarty, Ph.D., Director, Modeling and Simulation (DMPK), Takeda Pharmaceuticals International Co.

This session will focus on the application of Quantitative Systems Pharmacology in the pharmaceutical industry setting. The session will be practically focused, addressing real-world issues faced in pharma. Admirers and skeptics of QSP will both find the session useful, as speakers will draw out key themes that are discussed and debated in the hallways of our respective organizations:
- What does QSP offer that ‘traditional’ PK/PD modeling doesn’t?
- How do we know that our QSP models ‘work’?
- What are the key factors driving the effective use of QSP?

3:35 Right Target, Right Dose, Right Trial with Limited Animal Use: QSP Doubles the 3R Benefits

Valeriu Damian-Iordcahe, Ph.D., Head, Modelling and Translational Biology, GSK

Lack of efficacy is the most significant reason for late stage clinical failures. Drug discovery efforts are often based on qualitative link between the target and clinical outcomes and are supported by studies using animal models that may have limited clinical translation. Quantitative Systems Pharmacology provides the missing quantitative link between the target modulation and clinical outcomes allowing the selection of the best target, estimating the optimal target engagement, identifying the patients that would benefit the most from the therapy, and enabling the design of best trial. In this talk I will demonstrate these QSP benefits by using several case studies in dermatology, rare diseases and ophthalmology.

4:05 The QSP Extensibility Concept: A Physiology-Based Multi-Scale Model as a Platform to Address Wide-Ranging Clinical Questions

Mark C. Peterson, Ph.D., Director, Global Pharmacometrics, GIPB Clinical Pharmacology, Pfizer, Inc.

A key aspect of QSP models (QSPMs) is the multi-scale linking of target modulation to clinical outcomes (efficacy, safety). The physiologic linking renders a tool for asking/answering clinically relevant trial design and program development questions. Beyond the initial application, added value and accelerated understanding can be derived in alternate pathologies via QSPM extension. In this session, extensions of an existing QSPM will be presented, highlighting cross-disease area utility.

4:35 Creating and Performing Research with PhysioPD™ Research Platforms: Overview and Case Study

5:40 Diverse Application with a Common Underlying Workflow

Dr. Kapil G. Gadkar, Senior Scientist, Genentech

QSP can be applied to numerous therapeutic areas and throughout the drug development process, from research to late clinical stages. Furthermore, QSP encompasses a broad range of technical approaches and model types. One significant consideration for the robust execution of QSP projects is a general workflow relevant to different model types and applications. Here we present a unified workflow along with diverse examples of QSP efforts in our group in which it has been applied.

6:10 Building Translational Quantitative Pharmacology: The Merck Experience

Prajakti Kothare, Ph.D., Scientific Lead, Early Phase Quantitative Pharmacology & Pharmacometrics, Pharmacokinetics, Pharmacodynamics & Drug Metabolism, Merck

The emerging discipline of Quantitative and Systems Pharmacology has generated increasing interest recently across industry, academia and regulators. Built on the successful implementation of model-informed drug development, Merck has focused its efforts in the last few years on building similar capabilities in drug discovery. An overview of Merck’s experience in building translational and quantitative pharmacology in the discovery space will be presented and exemplified through case studies. A broad-based integration of these approaches through all facets of the discovery paradigm is critical to improving the probability of success to downstream pipeline milestones.

8:55 A Quantitative Systems Pharmacology (QSP) Framework for Oncology Translational and Early Clinical Development

Arijit Chakravarty, Ph.D., Director, Modeling and Simulation (DMPK), Takeda Pharmaceuticals International Co.

We have developed a QSP framework for translational and early clinical development that is underpinned by an assumption of cancer as an evolutionary process. Our framework is based on rigorous empirical assessments in the preclinical and early clinical settings, and relies on the assessment and iterative refinement of model-based decision analytics as the guiding principle for early development. The proposed talk will outline the framework and provide examples of its application in a range of different contexts.

2:20 Implementing a Quantitative Systems Pharmacology Platform for Drug Discovery in Academia.

Lansing Taylor, Ph.D., Director, University of Pittsburgh Drug Discovery Institute & Allegheny Foundation, Professor of Computational and Systems Biology, University of Pittsburgh

A sufficient understanding of the biology underlying how disease phenotypes arise from predisposing genetic variations is often the limiting determinant for optimal target and companion biomarker selection for therapeutic development and patient stratification. Consequently, drug candidates exhibiting well defined pharmacokinetic and pharmacodynamics profiles entering Phase II and III trials often fail to demonstrate proof-of-concept. To address this challenge, we describe a broadly applicable, network-centric, quantitative systems pharmacology (QSP) drug discovery and development platform to complement and enhance current target-focused and phenotypic-based approaches. The integration of the clinical, computational and experimental elements of QSP will be addressed in examples from metastatic breast cancer, Huntington’s Disease and Liver diseases.

Istvan Enyedy, Ph.D., Senior Scientist, Chemistry and Molecular Therapeutics, Biogen

We have built databases using in-house or literature compounds with measured hERG patch clamp IC50, volume of distribution, P450 inhibition IC50, MDCK permeability. This data was used to test the usefulness of kriging as a method for building in silico prediction tools. We tested the validity of the models using leave one class out approach which should be the most challenging for kriging. The advantages and disadvantages of this method will be presented.

4:30 A Massively Orthogonal Pharmacology Search Engine: Can All of Our Models and Data Be “GoogledTM”?

Douglas Selinger, Ph.D., Manager, Bioinformatics, Preclinical Safety, Novartis Institutes for BioMedical Research

We’ve developed a search engine which returns target data & predictions for a query small molecule. The search is automatically expanded to include compounds with structural similarity or a shared biological response, e.g. a similar transcriptional profile. Targets are then prioritized by consensus, as well as by algorithms such as PageRank, the algorithm made famous by GoogleTM. Despite searching large numbers of heterogeneous data sets and in silico model results (currently >15 models and/or data sets; ~200 million data)
