Validate Your Expertise in PK/PD NCA Analysis Through Certara Professional Certification

Maria Saluta

In the ongoing commitment to education and coinciding with the launch of Phoenix 8.1, Certara has introduced a new certification program available through Certara University. The new online accreditation program validates the scientists’ PK/PD data analysis skills using Certara software such as Phoenix WinNonlin and expands their professional reach. I caught up with Ana Henry, […]

Using Model-based Meta-analysis to Improve Decision-making in Drug Development

Making the right choices in drug development often means the difference between getting a new medication to patients and it ending up in the scrap heap of failed programs. There is a surfeit of publicly available information on approved drugs as well as those currently in development. How can sponsors turn clinical trial data into understanding that helps chart the course for investigational drugs?

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 […]

PBPK Modeling in Regulatory Review, Product Labeling and Safety Monitoring

Physiologically-based pharmacokinetic (PBPK) modeling can address various questions raised in drug development and regulatory review, and is used most extensively to predict and quantify the extent of drug-drug interactions (DDIs) from both in vitro and clinical data. This assists with dose selection and the design of clinical studies as well as informing decisions relating to […]

How to Optimize Your Drug Label Using Biosimulation Methodology

While biosimulation has been an important element in drug development for some time, its impact over the past 18 months with regard to label optimization has been profound. Specifically, FDA’s acceptance of Physiologically-Based Pharmacokinetic (PBPK) modeling and simulation has impacted key label elements in more than a dozen cases, driving down R&D costs and timelines, […]

Modeling and Simulation to Support Phase 2 Dose Selection for RG7652, a Fully Human Monoclonal Antibody Against Proprotein Convertase Subtilisin/Kexin Type 9

RG7652 is a fully humanized monoclonal antibody targeting human PCSK9, a regulator of serum low density lipoprotein cholesterol (LDLc) levels. RG7652 prevents degradation of the hepatic LDLc receptors by blocking PCSK9 binding and thereby resulting in efficient LDLc uptake by hepatocytes. The pharmacokinetics of RG7652 have been evaluated in healthy subjects after single and multiple […]

The Effect of Plasmapheresis on Blood Pressure in Voluntary Plasma Donors

Donor plasmapheresis involves the removal of a weight-adjusted volume of plasma and the return of cellular components to the donor. Although plasma volume generally returns to normal, some residual effect on vital signs may be possible. This analysis was performed to determine the possible effects of plasmapheresis on blood pressure. A 16-week study was conducted […]

Lack of Angiopoietin-like-2 Expression Limits the Metabolic Stress Induced by a High-fat Diet and Maintains Endothelial Function in Mice

Angiopoietin-like-2 (angptl2) is produced by several cell types including endothelial cells, adipocytes and macrophages, and contributes to the inflammatory process in cardiovascular diseases. We hypothesized that angptl2 impairs endothelial function, and that lowering angptl2 levels protects the endothelium against high-fat diet (HFD)-induced fat accumulation and hypercholesterolemia. Acute recombinant angptl2 reduced (P<0.05) acetylcholine-mediated vasodilation of isolated […]
