Venetoclax is a selective, first-in-class, B-cell lymphoma-2 inhibitor that has demonstrated clinical efficacy in several hematological malignancies. Two studies evaluated the relative bioavailability of venetoclax in healthy subjects: (1) a bioequivalence study to compare the bioavailability of the film-coated tablet with that of an earlier uncoated tablet(More)
Venetoclax (ABT-199/GDC-0199) is a selective, potent, first-in-class BCL-2 inhibitor that restores apoptosis in cancer cells and has demonstrated clinical efficacy in a variety of hematological malignancies. The objective of this analysis was to characterize the population pharmacokinetics of venetoclax and identify demographic, pathophysiologic, and(More)
Application of transdermal drugs to different anatomical sites can result in different absorption characteristics. The pharmacokinetics (PKs) and bioequivalence of a single 2.6 mg/kg (50 μL/kg) dose of a novel, long-acting transdermal fentanyl solution were determined when applied topically to the ventral abdominal or dorsal interscapular skin of 40 healthy(More)
Opioid overdose in dogs is manifested by clinical signs such as excessive sedation, bradycardia, and hypothermia. The ability of two different intramuscular (i.m.) naloxone reversal regimens to reverse the opioid-induced effects of a fivefold overdose of long-acting transdermal fentanyl solution was evaluated in dogs. Twenty-four healthy Beagles were(More)
A novel, transdermal fentanyl solution (TFS) was developed that delivers sustained concentrations of fentanyl for days following a single application. The pharmacokinetics following a single topical dose was examined. Eighteen adult Beagle dogs were divided into three groups of six dogs (3M, 3F). Each group was administered a single dose of 1.3 (25), 2.6(More)
A prospective, double-blinded, positive-controlled, multicenter, noninferiority clinical study was conducted to evaluate the safety and effectiveness of a long-acting transdermal fentanyl solution (TFS) for the control of postoperative pain. Four hundred forty-five client-owned dogs of various breeds were randomly assigned to receive a single dose of TFS(More)
Previous studies have demonstrated that a single, topical application of a novel, long-acting transdermal fentanyl solution provides analgesic fentanyl concentrations for at least 4 days. The objective of this study was to describe the margin of safety following application at multiples of the therapeutic dose. Twenty-four laboratory dogs were administered(More)
Gemcitabine is a relatively new chemotherapeutic compound used to treat a variety of cancers in dogs. Previous work presented in a companion paper explored the plasma kinetics of gemcitabine and its inactive metabolite, 2',2'-difluorodeoxyuridine (dFdU), in dogs after an intravenous bolus gemcitabine dose and demonstrated the saturation of intracellular(More)
Gemcitabine is a chemotherapeutic agent used to treat a variety of cancers in humans and dogs. In this study, the plasma pharmacokinetics of gemcitabine and its inactive metabolite, 2',2'-difluorodeoxyuridine (dFdU), were investigated in dogs after intravenous bolus gemcitabine doses of 3, 10, and 30 mg/kg. Furthermore, the intracellular accumulation of the(More)
A novel, long-acting transdermal fentanyl solution (TFS) that delivers sustained plasma fentanyl concentrations following a single application for the control of postoperative pain has recently been approved for use in dogs. The pharmacokinetics (PKs) of this formulation have been evaluated in healthy laboratory dogs, but they have not been reported in a(More)
