Emerging Issues for Pharma R&D: A Practical Approach for Pediatric Drug Programs

In this webinar, Dr. Barry Mangum from Paidion Research and Dr. JF Marier from Certara discussed how pediatric considerations fit into the overall drug development program. They also made recommendations for addressing issues from both a practical and scientific perspective. Anonymized case studies were presented with a review of historical issues with a focus on solutions for today (ie, licensed comparators differences in US and EU, importation issues, and endpoint selection).

Learning from Failure: Leveraging Biosimulation for Pediatric Drug Development Success

The high rate of trial failures, increasing regulatory demands, and ethical imperatives all require a reexamination of the current approach to pediatric drug development. Biosimulation is a proven approach that will help optimize trial design and inform the drug label. This approach can support global regulatory strategies that increase the likelihood of success for pediatric drug development programs.

Pharmacokinetic Profile of Defibrotide in Patients with Renal Impairment

Hepatic veno-occlusive disease, also called sinusoidal obstruction syndrome (VOD/SOS), is an unpredictable, potentially life-threatening complication of hematopoietic stem cell transplant conditioning. Severe VOD/SOS, generally associated with multiorgan dysfunction (pulmonary or renal dysfunction), may be associated with >80% mortality. Defibrotide, recently approved in the US, has demonstrated efficacy treating hepatic VOD/SOS with multiorgan dysfunction. Because renal […]

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

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) […]

Population Pharmacokinetic Analysis of Thrombomodulin Alfa to Support Dosing Rationale in Patients with Renal Impairment

Thrombomodulin alfa is a soluble recombinant human thrombomodulin that was reported to enhance the reversal of disseminated intravascular coagulation (DIC) in subjects with sepsis or hematologic malignancy and reduce mortality in subjects with sepsis and DIC. Population pharmacokinetic (PK) analysis of thrombomodulin alfa was performed based on rich samples collected in 24 healthy subjects (0.02 […]

Modeling and Simulation to Support Pediatric Drug Development

Conducting clinical drug trials in children poses numerous practical and ethical challenges. The benefits of using modeling and simulation for pediatrics include an increased likelihood of success, a reduced trial duration, and minimizing blood draws. In this presentation, Dr. JF Marier discussed how to use modeling and simulation to address the challenges of pediatric drug […]

The Effect of Plasmapheresis on Blood Pressure in Voluntary Plasma Donors

Donor plasmapheresis involves the removal of a weight-adjusted volume of plasma and the return of cellular components to the donor. Although plasma volume generally returns to normal, some residual effect on vital signs may be possible. This analysis was performed to determine the possible effects of plasmapheresis on blood pressure. A 16-week study was conducted […]

Modeling and Simulation for Medical Product Development and Evaluation: Highlights from the FDA-C-Path-ISOP 2013 Workshop

Medical-product development has become increasingly challenging and resource-intensive. In 2004, the Food and Drug Administration (FDA) described critical challenges facing medical-product development by establishing the critical path initiative. Priorities identified included the need for improved modeling and simulation tools, further emphasized in FDA’s 2011 Strategic Plan for Regulatory Science. In an effort to support and […]

Population Pharmacokinetic Analysis of Dutogliptin, a Selective Dipeptidyl Peptidase-4 Inhibitor

Dutogliptin is a selective dipeptidyl peptidase-4 inhibitor shown to be efficacious and safe in patients with type 2 diabetes mellitus (T2DM). Population pharmacokinetic (PK) analysis of dutogliptin was performed based on data collected in 561 healthy subjects and patients with T2DM enrolled in Phase I and II studies to assess sources of variability and support […]

An Evaluation of the Pharmacokinetics of Treprostinil Diethanolamine in Subjects with Hepatic Impairment

Treprostinil diolamine (oral treprostinil) is a prostacyclin analogue under evaluation for the treatment for pulmonary arterial hypertension (PAH). This study assessed the pharmacokinetics (PK) and safety of treprostinil following oral administration of a single sustained-release 1 mg dose in subjects with hepatic impairment. Four cohorts, including healthy volunteers, and subjects with mild, moderate and severe hepatic […]
