研究组 & 干预措施
Vismodegib + rosiglitazone
Participants received rosiglitazone 4 mg orally on Days 1 and 8 of the study. Participants also received vismodegib 150 mg orally once a day beginning on Day 2 until one of the following occurred; disease progression, intolerable toxicity, most probably attributable to vismodegib, or patient withdrawal of consent.
干预措施: Vismodegib (Drug)
Vismodegib + rosiglitazone
Participants received rosiglitazone 4 mg orally on Days 1 and 8 of the study. Participants also received vismodegib 150 mg orally once a day beginning on Day 2 until one of the following occurred; disease progression, intolerable toxicity, most probably attributable to vismodegib, or patient withdrawal of consent.
干预措施: Rosiglitazone (Drug)
Vismodegib + oral contraceptive
Participants received the oral contraceptive norethindrone 1 mg/ethinyl estradiol 35 µg (Ortho-Novum 1/35®) orally on Days 1 and 8 of the study. Participants also received vismodegib 150 mg orally once a day beginning on Day 2 until one of the following occurred; disease progression, intolerable toxicity, most probably attributable to vismodegib, or patient withdrawal of consent.

结局指标
主要结局
Geometric Mean Ratio of the Area Under the Plasma Concentration-time Curve From 0 to Infinity (AUC[0-inf]) of Rosiglitazone
时间窗: Pre-dose and 30 minutes, and 1, 2, 3, 4, and 6 hours, between 8 and 12 hours, and 24 hours post-dose
On Days 1 and 8, blood samples were taken prior to the administration of rosiglitazone and 30 minutes, and 1, 2, 3, 4, and 6 hours, between 8 and 12 hours, and 24 hours post-dose. Plasma concentrations of rosiglitazone were determined using a validated liquid chromatography mass spectrometry/mass spectrometry (LC MS/MS) assay. Individual and mean plasma rosiglitazone concentration versus time data were tabulated and plotted by analyte. The pharmacokinetic parameters of each analyte were calculated using standard non-compartmental methods (WinNonlin version 5.2.1, Pharsight Corp., Mountain View, CA). The geometric mean ratio of AUC(0-inf) of rosiglitazone was defined as the AUC(0-inf) of rosiglitazone on Day 8/AUC(0-inf) of rosiglitazone on Day 1.
Geometric Mean Ratio of the Area Under the Plasma Concentration-time Curve From 0 to Infinity (AUC[0-inf]) of Ethinyl Estradiol and Norethindrone
时间窗: Pre-dose and 30 minutes, and 1, 2, 3, 4, and 6 hours, between 8 and 12 hours, and 24 hours post-dose
On Days 1 and 8, blood samples were taken prior to the administration of the contraceptive norethindrone 1 mg/ethinyl estradiol 35 µg (Ortho-Novum 1/35®) and 30 minutes, and 1, 2, 3, 4, and 6 hours, between 8 and 12 hours, and 24 hours post-dose. Plasma concentrations of ethinyl estradiol and norethindrone were determined using a validated liquid chromatography mass spectrometry/mass spectrometry (LC MS/MS) assay. Individual and mean plasma ethinyl estradiol and norethindrone concentration versus time data were tabulated and plotted by analyte. The pharmacokinetic parameters of each analyte were calculated using standard non-compartmental methods (WinNonlin version 5.2.1, Pharsight Corp., Mountain View, CA). The geometric mean ratios of AUC(0-inf) of ethinyl estradiol and norethindrone were defined as the ratios of AUC(0-inf) of ethinyl estradiol and norethindrone on Day 8 divided by AUC(0-inf) of ethinyl estradiol and norethindrone on Day 1, respectively.
Geometric Mean Ratio of the Maximum Plasma Concentration (Cmax) of Rosiglitazone
时间窗: Pre-dose and 30 minutes, and 1, 2, 3, 4, and 6 hours, between 8 and 12 hours, and 24 hours post-dose
On Days 1 and 8, blood samples were taken prior to the administration of rosiglitazone and 30 minutes, and 1, 2, 3, 4, and 6 hours, between 8 and 12 hours, and 24 hours post-dose. Plasma concentrations of rosiglitazone were determined using a validated liquid chromatography mass spectrometry/mass spectrometry (LC MS/MS) assay. Individual and mean plasma rosiglitazone concentration versus time data were tabulated and plotted by analyte. The pharmacokinetic parameters of each analyte were calculated using standard non-compartmental methods (WinNonlin version 5.2.1, Pharsight Corp., Mountain View, CA). The geometric mean ratio of Cmax of rosiglitazone was defined as the Cmax of rosiglitazone on Day 8/ Cmax of rosiglitazone on Day 1.
