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) […]

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 and Pharmacodynamic Modeling to Determine the Human Dose of ST-246(R) to Protect Against Smallpox.

Although smallpox has been eradicated, the United States government considers it a “material threat” and has funded the discovery and development of potential therapeutic compounds. As reported here, the human efficacious dose for one of these compounds, ST-246, was determined using efficacy studies in nonhuman primates (NHPs), together with pharmacokinetic and pharmacodynamic analysis that predicted […]

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 […]

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 […]

Pharmacokinetics of SN2310, an injectable emulsion that incorporates a new derivative of SN-38 in patients with advanced solid tumors

SN2310 is an injectable emulsion composed of vitamin E, a succinate derivative, as well as 7-ethyl-10-hydroxycamptothecin (SN-38), the active metabolite of irinotecan. Single intravenous doses of 15, 20, 25, and 30 mg/m2 of SN2310 emulsion were administered in a total of 26 patients with advanced solid malignancies.
