Inclusion criteria

* Histologic documentation of incurable, locally advanced, or metastatic solid malignancy that has failed to respond to at least one prior regimen or for which there is no standard therapy * Documented negative serum pregnancy test for women of childbearing potential and use of two forms of contraception. Contraception must be used while the patient is enrolled in the study and for 12 months after the patient discontinues from the study. * For men with female partners of childbearing potential, agreement to use a latex condom and to advise their female partner to use an additional method of contraception during the study and for 3 months after their last dose of GDC-0449. * Agreement not to donate blood or blood products during the study and for at least 12 months after their last dose of GDC-0449 * For male patients, agreement not to donate sperm during the study and for at least 3 months after their last dose of GDC-0449 * Adequate hematopoietic capacity * Adequate renal function * Adequate hepatic function * At least 3 weeks since the patient's last chemotherapy, investigational agent, radiation therapy, or major surgical procedure and recovery to pre-treatment baseline or stabilization of all treatment-related toxicities

Exclusion criteria

* Active infection requiring intravenous (IV) antibiotics * Clinically important history of liver disease significantly impairing hepatic function, including active viral or other hepatitis, current alcohol abuse, or cirrhosis * Any medical condition or diagnosis that would likely impair absorption of an orally administered drug * Pregnant or lactating * Treatment with excluded medications, including strong CYP450 inhibitors and inducers, within 2 weeks of study entry * Male patients already receiving rosiglitazone * Male patients with a known contraindication to rosiglitazone * Female patients already receiving oral contraception \< 14 days prior to Day 1 * Female patients with known contraindication to oral contraceptions

Geometric Mean Ratio of the Area Under the Plasma Concentration-time Curve From 0 to Infinity (AUC[0-inf]) of RosiglitazonePre-dose and 30 minutes, and 1, 2, 3, 4, and 6 hours, between 8 and 12 hours, and 24 hours post-doseOn 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.

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.
