Considering Age Variation When Coining Drugs as High versus Low Hepatic Extraction Ratio

The hepatic extraction ratio (EH) is commonly considered an “inherent attribute” of drug. It determines the main physiological and biological elements of the system (patient attributes) that are most significant in interindividual variability of clearance. The EH consists of three age-dependent parameters: fraction of unbound drug in blood (fu.B), hepatic intrinsic clearance of unbound drug […]

Model-based covariate pharmacokinetic analysis and lack of cortisol suppression by the new inhaled corticosteroid ciclesonide using a novel cortisol release model

Ciclesonide is a novel and effective inhaled corticosteroid for the treatment of asthma that is converted into the active metabolite C21-desisobutyryl-ciclesonide (des-CIC) in the lung. The objectives of this analysis were to characterize covariate effects on des-CIC pharmacokinetics (PK) and circadian cortisol release. In addition, the effect of systemic des-CIC exposure on circadian cortisol release […]

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.

Physiologically-Based Pharmacokinetics Modeling: An Approach for Designing Better Clinical Trials

In this webinar, Dr. Marylore Chenel, director of Pharmacometrics at Servier, discussed how PBPK modeling is a tool that can help sponsors design better clinical studies. She illustrated this approach using two case studies. The first case study demonstrated how to evaluate potential drug-drug interactions (DDIs) with PBPK models and design multi-response sampling strategies using […]

Conducting Virtual Trials Using PBPK to Drive More Precise Label Claims

Biosimulation technology is revolutionizing the way in which the pharmaceutical industry does business and how the regulators are reviewing new drug approvals. Biosimulation leverages both empirical analysis of clinical data and mechanistic in silico approaches. The latter approach encompasses both in vitro-in vivo extrapolation (IVIVE) and physiologically-based pharmacokinetic modeling and simulation (PBPK M&S).

Physiologically-based Modeling Supports Drug Development Decisions, Regulatory Interactions and Drug Labeling

Today’s powerful and actively evolving computational tools enable sponsors and regulators to understand potential drug characteristics and subject responses earlier in development, with greater certainty. Model-based approaches support timely, confident decisions across the development and regulatory life cycle by gathering disparate sources of information about a drug, its competitors, target disease and patients into a […]
