The Roundtable: Our Thoughts About Model Based Drug Development

Expanding the Use of Pharmacometrics in Japan with Yusuke Tanigawara

Suzanne Minton

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 […]

Mechanistic Modeling of Genome Scale Molecular Interaction Networks

Andrzej Kierzek

Upon the completion of the Human Genome Project, the lead investigator, Dr. Francis Collins remarked: Science is a voyage of exploration into the unknown. We are here today to celebrate a milestone along a truly unprecedented voyage, this one into ourselves. Alexander Pope wrote, “Know then thyself. Presume not God to scan. The proper study […]

Nurturing the Pharmacometricians of the Future

Suzanne Minton

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 […]

Mind the Gap: Best Practices in Clinical Pharmacology Gap Analysis

Julie Bullock

Do you get anxious about taking tests? Many people do because they want to show their best efforts. Submitting your New Drug Application (NDA) to the FDA can be thought of as the ultimate test of a drug program. Are you confident that you’ll have robust answers to the 40 different questions that the agency […]

PBPK Modeling of Supersaturating Drug Product Behavior

David Turner

The problem of supersaturating drug products might loosely be summed up as: “If you’re not part of the solution, you’re part of the precipitate!” Indeed, more than 60% of new drug candidates are poorly soluble1 which can severely limit their bioavailability. To ameliorate this issue, a common approach is formulating to create supersaturated solutions of […]

Using Pharmacokinetics to Assure Chemical Food Safety

Ronette Gehring

As a veterinarian, I’m responsible for the health and welfare of my animal patients. Sometimes, drugs are used to treat animals that are being raised for food (e.g., meat and milk). Therefore, tissue residues are a unique concern in veterinary medicine because indirect exposure to drugs and their metabolites through eating meat or milk could […]

Navigating the Path for Pharmacokinetic CDISC Data Preparation

Maria Saluta

Data heterogeneity is a regulatory reviewer’s nightmare. Some sponsors talk about patient “gender” whereas others list the patient’s “sex.” What about date formats? Do you use the American-style month-day-year format or the European-style day-month-year? Inconsistent data presentation makes both collaborating on drug development projects and reviewing regulatory submissions more difficult. To address this challenge, the […]

Predicting Drug Exposure During Pregnancy Using PBPK Models

Suzanne Minton

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. […]

New Tools Support Developing Better TB Drugs

I. Gardner & O. Hatley

Tuberculosis (TB)—caused by infection with the mycobacterium Mycobacterium tuberculosis—is one of the top 10 leading causes of death worldwide with a total of 1.8 million people dying from the disease in 2015. TB is also the leading cause of death in HIV-infected individuals. TB usually attacks the lungs but can infect any part of the […]

The Ides of March – FDA’s Pharmaceutical and Clinical Pharmacology Advisory Committee Meeting

Ellen Leinfuss

While ominously scheduled for March 15, no such drama (like the assassination of Julius Caesar, the origins of ‘beware the Ides of March’) occurred during the FDA’s Pharmaceutical Science and Clinical Pharmacology Advisory Committee meeting. It was quite productive, acknowledging the tremendous impact of modeling and simulation in drug development and regulatory review moving the technology further into the mainstream.

EMA Policy 0070 Compliance Tips from James Bond

Lora Killian

In many ways, the strategic planning required to comply with EMA Policy 0070―a requirement to publish anonymized versions of clinical study reports (CSRs) and other submission documents―is similar to a secret agent’s mission: sponsors must keep the identities of people named or referred to in those documents top-secret while maintaining the document’s clinical utility. In […]

Modeling Delayed Outcomes in PK/PD Studies Using DDEs

Shuhua Hu

Delays are ubiquitous in pharmacokinetics (PK) and pharmacodynamics (PD) studies. Transit compartment models, described by systems of ordinary differential equations, have been widely used to describe delayed outcomes in PK and PD studies. The obvious disadvantage for this type of model is it requires manually finding proper values for the number of compartments. In addition, […]

The Model-Informed Precision Dosing Revolution Is Coming

Suzanne Minton

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 […]

Leveraging PBPK Modeling and Simulation for Neonatal and Infant Drug Development

Alice Ke

Despite increased regulatory support for pediatric drug development, sponsors still face ethical, economic and practical constraints. Indeed, while children represent about 40% of the world’s population, only 10% of the drugs on the market have been approved for pediatrics. Children are not small adults, and all children are not the same. In particular, children under […]

Accessing Grid Computing from Your Desktop for NLME

Fred Soltanshahi

One of the most challenging aspects of population pharmacokinetic/pharmacodynamic (PK/PD) modeling is the lack of computing power required to solve complex models in a reasonable time frame to support rapid drug development decisions. The explosion of cloud computing resources has provided access to significant computing power to solve these complex models. However, accessing these cloud […]

Prediction of Liver Volume; One Size Doesn’t Fit All!

Ben Small

When your physician writes you a prescription, they do so knowing that the dose prescribed will (on average) be safe and beneficial to you, but that it is likely certainly not optimal for you as an individual (as has been the topic of a previous blog post). The balance between absorption, distribution and elimination of […]

Streamline Your Approach to EMA Policy 0070

Lora Killian

Policy 0070― published by the European Medical Agency (EMA) in October 2014― has made the world of regulatory writing a more complicated place. The policy requires specified submission documents to be made public for all marketing authorization applications (MAA’s) submitted as of January 1, 2015 and for all indication extensions and line extensions submitted as […]

Transforming Drug Product Development the PBPK Way! -A Breakthrough Approach

Shriram Pathak

Developing and optimizing drug formulations― a key component of a product development―is a very lengthy and capital intensive process. Today, most drug candidates are poorly water-soluble; this has led to greater emphasis on screening more complex formulation technologies. Formulation development is still largely an empirical process ― based on trial and error and formulation scientists’ […]
