Modeling PK/PD Systems with Distributed Delays

Many biological systems exhibit time delays. For instance, there is a delay between the time that a virus infects a cell and the onset of viral production. Mathematical models that incorporate these temporal delays are often used to characterize the pharmacokinetics/pharmacodynamics (PK/PD) of drugs. In this blog post, I’ll discuss some examples of biological systems […]

Expanding the Use of Pharmacometrics in Japan with Yusuke Tanigawara

Science is a global endeavor. Indeed, one of the most exciting things about drug development is working with scientists doing important research all over the globe. The use of modeling and simulation (M&S) to support drug development has been embraced by pharmaceutical researchers in some parts of the world and is still gaining traction in […]

Nurturing the Pharmacometricians of the Future

As a scientist, you always remember your first conference. The ability to share your research and learn from your peers is an invaluable part of any scientist’s training. That’s why I’m so proud that Certara helps support the travel and accommodation expenses for a selected number of students wishing to attend the Population Approach Group […]

Predicting Drug Exposure During Pregnancy Using PBPK Models

Moms want the best for their kids even before they’re born. When I was pregnant with my son and daughter, I watched my diet and tried to stay active. During both of my pregnancies, I had to take medications several times. And I was always concerned about whether the medications could impact my unborn children. […]

The Model-informed Precision Dosing Revolution Is Coming

Modeling and simulation (M&S) has been widely accepted and adopted by biopharmaceutical companies and global regulatory agencies. However, its implementation in clinical care has been modest to date. Model-based approaches are essential to realize the goal of precision dosing—providing the right drug dose to maximize therapeutic benefit, while reducing risk for each individual patient. The […]

How Model-informed Drug Development Will Increase R&D Productivity

Will 2017 finally be the year that we overcome the blight of late-stage attrition of promising drug candidates? In a recent commentary, “Improving the Tools of Clinical Pharmacology: Goals for 2017 and Beyond,” in Clinical Pharmacology & Therapeutics, Issam Zineh and colleagues describe several areas where clinical pharmacology approaches can help reduce late-stage attrition and […]

Optimizing Drug Development Decisions: Looking Back at 2016

Was it just me or did 2016 just seem to fly by? Reflecting on the events of the past year, I stumbled across this quote which seemed appropriate: There are years that ask questions and years that answer. [Zora Neale Hurston, Their Eyes Were Watching God] Our mission at Certara is helping our clients optimize […]

How PBTK Models Support Toxicological Triage

Did you know that only a small fraction of the tens of thousands of commercially-used chemicals have undergone toxicological assessment? Time and cost constraints, not to mention the ethical impossibility of studying these chemicals in human trials, hamper large-scale toxicological assessment. Physiologically-based toxicokinetic (PBTK) models can be leveraged to predict TK from in vitro measurements […]

The Impact of Genetic Polymorphisms and DDIs on Exposure

Physiologically-based pharmacokinetic (PBPK) modeling and simulation is increasingly accepted due to the enormous cost and time saving benefits that can be realized through its ability to address regulatory concerns without always defaulting to clinical study — particularly relating to assessing complex drug-drug interactions (DDIs). Independent validation of simulations against clinical data provides confidence in the […]

How PBPK Can Help Solve Fatal Poisonings

My mom― a clinician scientist herself― would often say this about the power of pharmacology: Every medicine has its price. While most patients benefit from their medications, cases of fatal drug poisonings are tragedies wherein patients pay the ultimate price. Forensic toxicology probes cases of fatal poisonings where the cause of death is unknown. This […]

6 Real-life Lessons About PBPK Modeling

I recently had the pleasure of attending a 1.5 day Certara forum for management on the applications of physiologically-based pharmacokinetic (PBPK) modeling and simulation in Chicago, IL. Our CSO Dr. Amin Rostami and Certara consulting scientist, Dr. Alice Ke aptly led the forum. The highlight of the meeting was discussing the latest challenges and trends […]

Effective Communication for Pharmacometricians with Joga Gobburu

The modeling and simulation revolution is transforming our approach to drug development. Quantitative pharmacology models can yield valuable insights that help sponsors make better decisions regarding their drug programs. For pharmacometricians to influence decision making, they must be able to effectively communicate. Dr. Joga Gobburu is a Professor at the University of Maryland Schools of […]

Inside the Mind of Pharmacometrics Pioneer, Professor Malcolm Rowland

Officially, Prof. Malcolm Rowland has retired. This scientific pioneer has been helping lay the foundation of a mechanistic understanding of pharmacokinetics since the 1960s. So you might think that he’d be ready for quieter pursuits. But this professor emeritus at the University of Manchester has no plans to stop actively teaching and guiding the pharmaceutical industry’s […]

Using Biosimulation to Support Approvals for Orphan Drugs

Rare diseases affect fewer than 1 in 2000 people. Each one affects only a small number of patients. Yet, there are over 7000 rare diseases. And, there are no treatments for 95 percent of them. Thus, many patients suffer from these diseases. The treatments for rare diseases are often referred to as “orphan drugs.” Orphan […]
