Pharmacometrics Skills Competition MIDD Gran Prix

Sitting around the Certara’s Raleigh office conference room, sketching out a pitch for a pharmacometrics contest at a national meeting, none of us were overly confident in its viability. Mark Lovern had been talking about the importance of communication skills for pharmacometricians. For them to influence critical drug development decisions, they should be able to […]

Using M&S to Evaluate Oncology Drug Dosing

There are numerous challenges in developing oncology drugs: (1) they are often very toxic which precludes conducting clinical trials in healthy volunteers, (2) the PK of a drug may be altered in cancer patients due to demographic and physiological differences as compared to healthy volunteers, and (3) cancer patients face elevated drug-drug interaction (DDI) risk […]

How to Maximize the Benefits of Clinical Pharmacology Gap Analysis

Many companies have tried and true clinical pharmacology practices. But when the rubber hits the road for your drug program, will these practices support regulatory success? Has your historic approach to drug development been updated to include the latest modeling and simulation innovations? It’s hard to change how you’ve historically done things. But, do you […]

Ready, Set, Model! Take PK/PD Analysis to New Heights with Phoenix 8.0

Dr. Scott Gottlieb, the Commissioner of Food and Drugs, has outlined the steps the US FDA will take to implement the 21st Century Cures Act. In outlining the plan, the Commissioner endorses modeling and simulation approaches to increase the efficiency of drug development. Certara has launched Phoenix® 8.0, the latest version of the innovative PK/PD […]

How Clinical Pharmacology Gap Analysis Can Create Value

During my years reviewing applications for the US FDA, I encountered a lot of poor planning concerning a drug’s clinical pharmacology program. This poor planning left the company either lacking data to make informed decisions or scrambling at the end of development to address unanswered issues. Early planning is key to regulatory success, not only […]

The Biggest Drug Development News Stories in 2017

When I reflect on the state of drug development in 2017, the opening lines of Charles Dickens’ A Tale of Two Cities comes to mind. It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, […]

A Practical Approach to the Challenges of Pediatric Drug Development

Drug developers can’t take an adult clinical trial protocol and simply retool it for pediatrics. Yet, in my work at a pediatric clinical research organization (CRO), I frequently see sponsors attempt to do just that. Successfully implementing a pediatric drug development plan poses challenges regarding trial planning, design, and conduct. In this blog post, I’ll […]

Phoenix Modeling Language School: The Semester in Review

Phoenix® WinNonlin® uses Phoenix Modeling Language (PML) to encode pharmacokinetic (PK) and pharmacodynamic (PD) models. Although most models can be built using the Phoenix graphical user interface (GUI), some models require custom coding with PML. During the latter part of 2016, Certara’s support team, led by Dr. Bernd Wendt, Director of Training and Support, introduced […]

The European Regulatory Landscape for Pediatric Drug Development

In my 35 years of working to develop safer, more effective medications for children, I’ve often been asked about how to navigate the regulatory landscape in the US and Europe. In a previous blog post, I discussed the latest FDA trends regarding pediatric drug development. In this blog, I’ll focus on the path for achieving […]

FDA Reauthorization Act (FDARA) Affirms Commitment to Innovative MIDD Strategies

Quietly, without any political rancor, the FDA Reauthorization Act of 2017 (FDARA) was passed by the US Congress and was signed into law by President Trump in late August. The FDARA reauthorizes the Prescription Drug User Act Fee Amendments (PDUFA) for the fifth time, the Medical Device User Act Fee Amendments (MDUFA) for the third […]

What the FDA Expects from Your Pediatric Drug Program

Historically, 80 percent of medicines used in children had little to no data guiding prescribers on proper use. To address this market failure, regulatory legislation for drug development in pediatric patients was passed worldwide over the past decade. The number of drugs tested in and labeled for children has increased dramatically as a result. In […]

New FDA Commissioner Endorses Use of M&S to Advance Drug Development

With the swearing in of Dr. Scott Gottlieb as Commissioner of Food and Drugs in May, many have wondered as to the climate he will set for the US FDA. Certara’s mission and business thesis aligns with the FDA’s July 7 announcement regarding the steps it is taking to implement the 21st Century Cures Act. […]

Speaking into the Ether: Challenges of the Virtual Pharma Workplace

In today’s global pharma working environment, virtual interactions are sometimes more common than live exchanges. Many people work virtually through teleconferences, video conferences, instant messaging, phone calls, and emails. Through flexible schedules and working remotely, some people spend the majority of their day without seeing or hearing their colleagues. Honing your skills Pharmacometricians are like […]

What are Clinical Trial Outcomes Databases? How and Why You Should Use Them

Publicly available clinical trial data represents an underutilized source of information. If properly extracted and analyzed, they provide valuable information to support drug development decisions. When you think of the volumes of public information and databases that are available to determine, for example, commercial viability of a therapeutic in development, your first inclination is—“great!” But […]

Feedback from the Phoenix Community: Our Visits with the FDA

We recently completed a week-long set of meetings with the FDA, where we met with over 300 FDA reviewers from 7 of the 11 FDA centers that use Phoenix. Here are a few topics that took center-stage during our visits: Q: How can we create Phoenix workflow templates that are reusable across different studies with […]

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 […]
