Laropiprant is a prostaglandin D2 receptor 1 antagonist that is being developed in combination with niacin for the treatment of dyslipidemia. This randomized clinical study evaluated the effect of laropiprant on the pharmacokinetics of ethinyl estradiol (EE) and norelgestromin (NGMN), the principal circulating metabolite of norgestimate, in healthy women receiving 3 or more months of an oral contraceptive (Ortho Tri-Cyclen; Ortho-McNeil Pharmaceutical, Raritan, NJ), which contains EE and norgestimate. Twenty-one female subjects with normal menstrual cycles received the oral contraceptive on Days 1 to 21 during two consecutive contraceptive cycles. Subjects received double-blind 40 mg/day laropiprant or placebo on Days 1 to 21 of each contraceptive cycle. Plasma samples were collected predose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours postdose on Day 21 to measure area under the plasma concentration-time curve from 0 to 24 hours (AUC0-24hr) and maximum concentration observed in plasma (Cmax) of EE and NGMN. Comparability would be declared if the 90% confidence intervals for the geometric mean ratio of AUC0-24hr and Cmax in the absence and presence of laropiprant were within predefined bounds (0.80-1.25). The estimated geometric mean ratios (90% confidence intervals) of EE and NGMN, respectively, were 1.08 (1.04-1.13) and 0.97 (0.94-0.99) for AUC0-24hr and 1.16 (1.06-1.27) and 1.00 (0.94-1.06) for Cmax. The 90% confidence intervals for the geometric mean ratio of EE Cmax minimally exceeded the prespecified bounds; the other relevant pharmacokinetic parameters fell within the predefined bounds. Coadministration of 40 mg laropiprant with the oral contraceptive did not lead to clinically meaningful alterations in the pharmacokinetics of EE or NGMN.

The determinants for gastroenteropancreatic neuroendocrine tumors (GEP-NET) recent burden are matters of debate. Obesity and metabolic syndrome (MetS) are well established risks for several cancers even though no link with GEP-NETs was yet established. Our aim in this study was to investigate whether well-differentiated GEP-NETs were associated with obesity and MetS. Patients with well-differentiated GEP-NETs (n = 96) were cross-matched for age, gender, and district of residence with a control group (n = 96) derived from the general population in a case-control study. Patients presented gastro-intestinal (75.0%) or pancreatic (22.9%) tumors, grade G1 (66.7%) or G2 (27.1%) with localized disease (31.3%), regional metastasis (16.7%) or distant metastasis (43.8%) at diagnosis, and 45.8% had clinical hormonal syndromes. MetS was defined according to Joint Interim Statement (JIS) criteria. Well-differentiated GEP-NETs were associated with MetS criteria as well as the individual components' waist circumference, fasting triglycerides, and fasting plasma glucose (p = 0.003, p = 0.002, p = 0.011 and p < 0.001, respectively). The likelihood of the association was higher when the number of individual MetS components was greater than four. MetS and some individual MetS components including visceral obesity, dyslipidemia, and increased fasting glucose are associated with well-differentiated GEP-NET. This data provides a novel insight in unraveling the mechanisms leading to GEP-NET disease.
