The Roundtable: Our Thoughts About Model Based Drug Development

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 […]

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

Suzanne Minton

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 […]

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’ […]

How MBMA Can Help You Make Smarter Drug Development Decisions

Leon Bax

Successful drug development depends on making wise decisions about portfolios, clinical trials, marketing, etc. We’re continuously faced with the challenge of deciding whether to continue development or stop it. To support those decisions, we gather data, typically through clinical trials. We analyze the data from those clinical trials, and then we use these analyses to […]

Leveraging Dissolution Testing to Meet Regulatory Guidelines

Jean-Michel Cardot

Dissolution testing is a standard tool in a formulation scientist’s arsenal. When companies make changes to drug products (particle size, excipients, manufacturing process, equipment, etc), health authorities often require comparing dissolution profiles to determine if the reference and test products are equivalent. Generic drug developers are also required to show bioequivalence between the branded drug […]

Optimizing Drug Development Decisions: Looking Back at 2016

Suzanne Minton

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 […]

PML School: Custom PK/PD Modeling Made Easy

Bernd Wendt

In our increasingly noise-filled world, sometimes, the most powerful insights come from listening. As the head of support at Certara, I get excited about listening to our clients’ pharmacokinetic/pharmacodynamic (PK/PD) modeling dilemmas and helping them solve them. And through listening to our users who call our support hotline, attend our training courses, or participate in […]

Best Practices in PBPK: The Case of Efavirenz

Lisa Almond

According to the FDA’s Guidance for Industry on Drug-drug interactions (DDIs), assessment of a new drug’s DDI liability has three major objectives: determining whether any interactions necessitate dosing adjustment, informing the extent of therapeutic monitoring that may be required and identifying any potential contraindications to concomitant use when lesser measures cannot mitigate risk Physiologically-based pharmacokinetic […]

How PBTK Models Support Toxicological Triage

Suzanne Minton

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 Ultimate Cheat Sheet on CDISC-SEND

Chris Lovejoy

On December 18, 2016, numerous regulatory agencies will require electronic submission of non-clinical data using CDISC’s standard format. What exactly are CDISC data standards and how will they impact drug developers? In this blog post, I will provide an overview of the CDISC SEND data standard, review some of the requirements for implementing SEND, and […]

The Impact of Genetic Polymorphisms and DDIs on Exposure

Suzanne Minton

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 […]

Modeling and Simulation Guides Dosing for a New Anti-psychotic Drug

Karen Rowland Yeo

Drug development is becoming more complex than ever. Regulatory agencies expect sponsors to consider a wide variety of intrinsic and extrinsic factors that could impact drug safety and efficacy. These factors include intrinsic variability― CYP metabolizer status, age, sex, renal/hepatic impairment― as well as external variables― co-medications, food effects, smoker status, etc. Clinical trials alone […]

How PBPK Can Help Solve Fatal Poisonings

Suzanne Minton

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 […]

Best Practices for Complying with EMA Policy 70

Lora Killian

EMA Policy 70 requires sponsors to publish anonymized versions of clinical study reports (CSRs) and submission documents submitted in support of a marketing authorization application (MAA) after January 1, 2015. Sponsors must prevent re-identification of people named or referred to in those documents. In March 2016, the detailed guidance document was published. This blog post […]

Quantitative Pharmacology Strategies for Pediatric Drug Development

Patrick Smith

Pediatric patients are not simply small adults. Children differ from adults in both disease pathophysiology and pharmacokinetics/pharmacodynamics (PK/PD). Yet historically, 80 percent of medicines used in children had little to no data guiding prescribers on proper use. In this blog post, I’ll discuss the challenges of developing drugs for children and explain how quantitative pharmacology […]
