A selection of short essays by Certara’s pediatric drug development experts. Learn about our technologies and strategies for pediatric drug development to inform dose selection, including PK/PD simulations using sparse data analysis and our Simcyp Pediatric Simulator. Certara’s regulatory writing consultancy, Synchrogenix, also offer regulatory strategy for pediatrics.
Physiologically-based pharmacokinetic (PBPK) modeling can address various questions raised in drug development and regulatory review, and is used most extensively to predict and quantify the extent of drug-drug interactions (DDIs) from both in vitro and clinical data. This assists with dose selection and the design of clinical studies as well as informing decisions relating to … Continued
To solve a mystery in clinical development for a promising new formulation to combat a rare disease, Certara performed physiologically relevant modeling.
X-linked hypophosphatemia (XLH) is an inherited metabolic bone disease with abnormally elevated serum FGF23 resulting in low renal maximum threshold for phosphate reabsorption, low serum phosphate (Pi) and 1,25-dihydroxyvitamin D levels with subsequent development of short stature and skeletal deformities. KRN23 is a novel human anti-FGF23 antibody for the treatment of XLH. The pharmacokinetics (PK) … Continued
Precision dosing― the right dose, for the right patient, at the right time― is crucial to providing patients with the most efficacious medications with minimal probability of adverse events. One key step towards achieving the delivery of individualized dosing is testing potential dosing regimens in a patient’s ‘virtual twin.’ The other key step is to … Continued
Obeticholic acid (OCA) is a selective and potent farnesoid X receptor (FXR) agonist in development for several chronic liver diseases. OCA is a semi-synthetic analogue of chenodeoxycholic acid (CDCA) with similar pharmacokinetic (PK) properties. There was a significant increase in systemic exposure of OCA in patients with hepatic impairment. A proportionally similar increase in systemic … Continued
While biosimulation has been an important element in drug development for some time, its impact over the past 18 months with regard to label optimization has been profound. Specifically, FDA’s acceptance of Physiologically-Based Pharmacokinetic (PBPK) modeling and simulation has impacted key label elements in more than a dozen cases, driving down R&D costs and timelines, … Continued
The number of submissions to the FDA involving physiologically-based pharmacokinetic (PBPK) modeling has increased significantly over the past few years. PBPK modeling can be applied in drug discovery and development from the early stages prior to lead development where limited data are available as well as in early to late drug development. There are now … Continued
Human African trypanosomiasis (HAT, sleeping sickness) ranks among the most neglected tropical diseases based on limited availability of drugs that are safe and efficacious, particularly against the second stage (central nervous system [CNS]) of infection. In response to this largely unmet need for new treatments, the Consortium for Parasitic Drug Development developed novel parenteral diamidines … Continued
