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 […]

Annual Report—Simcyp Consortium Meeting

Ellen Leinfuss

It may be 2016, but we just held the 17th annual Simcyp Consortium meeting in Sheffield, UK. This year’s gathering had >120 attendees with representatives from all but one of the 34 consortium member companies joining. The opening session reviewed the progress made by the Simcyp staff toward the field of regulatory science, physiologically-based pharmacokinetic […]

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 […]

Arming Adherence-based Drug Development with Pharmacometrics

Jonathan Knights

The time is right to explore how sensor-enabled digital adherence monitoring systems can benefit patients, sponsors, and payers. Non-adherence to prescribed medications is a key issue facing our healthcare industry, costing the US healthcare economy between $100-300 billion annually, representing between 3-10% of total healthcare costs.1,2 Further, non-adherence also decreases our ability to capture dose-response […]

Meet Pharma Transparency Mandates & Engage Study Participants

Behtash Bahador

Most clinical study participants want to know the results of trials they participated in. However, few are actually informed. Lack of communication and transparency jeopardizes the success of the clinical research enterprise. In this blog post, I’ll discuss a new model for communicating trial results in lay language with minimum added burden on sponsors and […]

Can QSP Save Lives? Lessons from a Trial Debacle

Neil Benson

The notion that volunteers could be harmed in a clinical trial is every drug developer’s worst nightmare. Earlier this year, the drug company, Bial, investigated inhibitors of the enzyme fatty acid amide hydrolase (FAAH) in clinical trials as a treatment for pain. Tragically, one person in the volunteer group died, and six patients were hospitalized. […]

How to Expedite FDA Approvals of Orphan Drugs

Thomas Peyret

350 million patients worldwide suffer from 7,000 rare diseases, yet only 300 of these diseases have approved treatments. This gap, impacting 95% of rare disease patients, represents a huge unmet medical need. Developing drugs for rare diseases poses a range of clinical, regulatory and commercial challenges. The small number of patients are difficult to identify […]
