[(14)C]Etoricoxib (100 microCi/dose) was administered to six healthy male subjects (i.v., 25 mg; p.o., 100 mg). Following the i.v. dose, the plasma clearance was 57 ml/min, and the harmonic mean half-life was 24.8 h. Etoricoxib accounted for the majority of the radioactivity (approximately 75%) present in plasma following both i.v. and p.o. doses. The oral(More)
BACKGROUND Aprepitant is a neurokinin(1) receptor antagonist that enhances prevention of chemotherapy-induced nausea and vomiting when added to conventional therapy with a corticosteroid and a 5-hydroxytryptamine(3) (5-HT(3)) antagonist. Because aprepitant may be used with a variety of chemotherapeutic agents and ancillary support drugs, which may be(More)
Adipocyte complement-related protein of 30 kDa (Acrp30, adiponectin, or AdipoQ) is a fat-derived secreted protein that circulates in plasma. Adipose tissue expression of Acrp30 is lower in insulin-resistant states and it is implicated in the regulation of in vivo insulin sensitivity. Here we have characterized the ability of PPARgamma agonists to modulate(More)
BACKGROUND Aprepitant is a neurokinin(1) receptor antagonist that, in combination with a corticosteroid and a 5-hydroxytryptamine(3) receptor antagonist, has been shown to be very effective in the prevention of chemotherapy-induced nausea and vomiting. At doses used for the management of chemotherapy-induced nausea and vomiting, aprepitant is a moderate(More)
[(18)F]MK-9470 is a selective, high-affinity, inverse agonist (human IC(50), 0.7 nM) for the cannabinoid CB1 receptor (CB1R) that has been developed for use in human brain imaging. Autoradiographic studies in rhesus monkey brain showed that [(18)F]MK-9470 binding is aligned with the reported distribution of CB1 receptors with high specific binding in the(More)
Cannabinoid 1 receptor (CB1R) inverse agonists are emerging as a potential obesity therapy. However, the physiological mechanisms by which these agents modulate human energy balance are incompletely elucidated. Here, we describe a comprehensive clinical research study of taranabant, a structurally novel acyclic CB1R inverse agonist. Positron emission(More)
AIMS To evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of odanacatib (ODN), a cathepsin K inhibitor, in humans. METHODS Two double-blind, randomized, placebo-controlled, single oral dose studies were performed with ODN (2-600 mg) in 44 healthy volunteers (36 men and eight postmenopausal women). RESULTS Adverse experiences (AEs)(More)
Neuropeptide Y (NPY) is a potent orexigenic neuropeptide, and antagonism of NPY Y1 and NPY Y5 receptors (NPYxR) is considered a potentially important anti-obesity drug target. We tested the hypothesis that blockade of the NPY5R will lead to weight loss in humans using MK-0557, a potent, highly selective, orally active NPY5R antagonist. The initial series of(More)
The alphaVbeta3 integrin (vitronectin receptor) plays a pivotal role in bone resorption. We hypothesized that L-000845704, an alphaVbeta3 integrin antagonist, would potently inhibit bone resorption, thereby increasing bone mass as assessed by bone mineral density (BMD) in women with postmenopausal osteoporosis. In a multicenter, randomized, double-blind,(More)
BACKGROUND Observational data and non-human primate challenge studies suggest that cell-mediated immune responses might provide control of HIV replication. The Step Study directly assessed the efficacy of a cell-mediated immunity vaccine to protect against HIV-1 infection or change in early plasma HIV-1 levels. METHODS We undertook a double-blind, phase(More)
