Can QSP Save Lives? Lessons from a Trial Debacle

Neil Benson

The notion that volunteers could be harmed in a clinical trial is every drug developer’s worst nightmare. Earlier this year, the drug company, Bial, investigated inhibitors of the enzyme fatty acid amide hydrolase (FAAH) in clinical trials as a treatment for pain. Tragically, one person in the volunteer group died, and six patients were hospitalized. […]

Learning from Failure: Leveraging Biosimulation for Pediatric Drug Development Success

The high rate of trial failures, increasing regulatory demands, and ethical imperatives all require a reexamination of the current approach to pediatric drug development. Biosimulation is a proven approach that will help optimize trial design and inform the drug label. This approach can support global regulatory strategies that increase the likelihood of success for pediatric drug development programs.

Development of a Permeability-limited Model of the Human Brain and Cerebrospinal Fluid (CSF) to Integrate Known Physiological and Biological Knowledge: Estimating Time Varying CSF Drug Concentrations and Their Variability Using In Vitro Data

A 4-compartment permeability-limited brain (4Brain) model consisting of brain blood, brain mass, cranial and spinal cerebrospinal fluid (CSF) compartments has been developed and incorporated into a whole body physiologically-based pharmacokinetic (PBPK) model within the Simcyp Simulator. The model assumptions, structure, governing equations and system parameters are described. The model in particular considers the anatomy and […]

Can QSP Save Lives? Lessons from the Bial Trial Debacle

One of the biggest challenges for the pharmaceutical industry is the high rate of drug attrition in Phase 2 clinical trials, which wastes significant amounts of money and time. The major reasons for this attrition are that either candidate drugs do not show efficacy or have unexpected toxicity, in turn implying that we did not fully understand the complexity of the biology the candidate drugs were designed to modulate.

Quantitative Systems Pharmacology Brings Value to Drug Development

Quantitative systems pharmacology (QSP) sits at the interface between pharmacometric modeling and simulation, and systems biology. It uses mathematics to describe biological processes. While pharmacokinetics describes what the body does to the drug, pharmacodynamics quantifies what the drug does to the body; the pharmacological response. QSP is a mechanistic modeling approach and an emerging technology, which mathematically integrates pharmacokinetics, pharmacological response and disease progress/modulation.

Learning From Failure, Leveraging Modeling and Simulation for Pediatric Drug Development Success

Historically, clinical trials have not examined most pediatric medications. This is due to the ethical and practical challenges of conducting pediatric drug trials. Children are 40 percent of the world’s population. Yet, regulatory agencies have approved only 10 percent of the drugs on the market for pediatrics.1 Without a proper clinical process, pediatricians are stuck […]

Precision Dosing Using PBPK Modeling

Precision dosing― the right dose, for the right patient, at the right time― is crucial to providing patients with the most efficacious medications with minimal probability of adverse events. One key step towards achieving the delivery of individualized dosing is testing potential dosing regimens in a patient’s ‘virtual twin.’ The other key step is to […]
