Summary
This randomized clinical trial studies the effect of food on the pharmacokinetics of vismodegib. Studying the effects of meals on the absorption of vismodegib may help doctors prescribe correct doses and label the drug accurately.

Eligibility Criteria
Inclusion Criteria
- Histologically confirmed advanced malignancies (except for leukemias) refractory to standard of care therapy, or for whom no standard of care therapy is available
- Measurable or non-measurable disease
- An anticipated life expectancy > 3 months
- Karnofsky performance status of > 70%
- Leukocytes >= 3,000/mcL
- Absolute neutrophil count >= 1,500/mcL
- Platelets >= 100,000/mcL
- Total bilirubin within normal institutional limits
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 X institutional upper limit of normal
- Creatinine =< 1.5 X institutional upper limit of normal
- Women of child-bearing potential and men must use two forms of contraception (i.e., barrier contraception and one other method of contraception) at least 4 weeks prior to study entry, for the duration of study participation, and for at least 12 months post-treatment; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
- Women of childbearing potential are required to have a negative serum pregnancy test (with a sensitivity of at least 25 mIU/mL) within 48 hours prior to the first dose of GDC-0449 (serum or urine); a pregnancy test (serum or urine) will be administered every 4 weeks if their menstrual cycles are regular or every 2 weeks if their cycles are irregular while on study within the 24-hour period prior to the administration of GDC-0449; a positive urine test must be confirmed by a serum pregnancy test; prior to dispensing GDC-0449, the investigator must confirm and document the patient's use of two contraceptive methods, dates of negative pregnancy test, and confirm the patient's understanding of the teratogenic potential of GDC-0449
- Female subjects of childbearing potential are defined as follows:
- Patients with regular menses
- Patients, after menarche with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding
- Women who have had tubal ligation
- Female subjects may be considered to NOT be of childbearing potential for the following reasons:
- The patient has undergone total abdominal hysterectomy with bilateral salpingo-oophorectomy or bilateral oophorectomy
- The patient is medically confirmed to menopausal (no menstrual period) for 24 consecutive months
- Pre-pubertal females; the parent or guardian of young female patients who have not yet started menstruation should verify that menstruation has not begun; if a young female patient reaches menarche during the study, then she is to be considered as a woman of childbearing potential from that time forward
- Ability to understand and the willingness to sign a written informed consent document
Exclusion Criteria
- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
- Patients may not be receiving any other investigational agents
- Patients with known brain metastases should be excluded from this clinical trial
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to GDC-0449 or other agents used in study
- Patients with malabsorption syndrome or other condition that would interfere with intestinal absorption; patients must be able to swallow capsules
- Patients with clinically important history of liver disease, including viral or other hepatitis or cirrhosis are ineligible
- Patients with uncontrolled hypocalcemia, hypomagnesemia, hyponatremia or hypokalemia defined as less than the lower limit of normal for the institution, despite adequate electrolyte supplementation are excluded from this study
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
