Population Pharmacokinetic and Pharmacodynamic Analyses from a 4-Month Intra-dose Escalation and Its Subsequent 12-month Dose Titration Studies for a Human Monoclonal Anti-FGF23 Antibody (KRN23) in Adults with X-linked Hypophosphatemia
Understanding the Relationship Between Systemic and Hepatic Exposure of Obeticholic Acid for the Treatment of Liver Disease in Patients with Cirrhosis
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 […]
Pediatric drug development can, in many ways, be described as a “Catch 22.” It is extremely challenging (both logistically and ethically) to enroll children in clinical trials, yet without a proper and approved clinical process, physicians are left with inaccurate dosing and therapeutic approaches for children. Modeling and simulation methods, including population PK modeling, are […]
When thinking about the challenges of oncology drug development, I recall the advice of the 6th century BCE military strategist, Sun Tzu: If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself, but not the enemy, for every victory gained you will also […]
