Eligibility Criteria

Male or female participants at least 19 years old.

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;

Additional Information

Official title Evaluation of Food Effect on Pharmacokinetics of GDC-0449, an Inhibitor of Hedgehog Signaling
Principal investigator Manish Sharma
Description PRIMARY OBJECTIVES: I. To evaluate the effect of prandial states on the pharmacokinetic parameters of GDC-0449 (vismodegib). II. To evaluate the effect of fat content of meals on the pharmacokinetic parameters of GDC-0449. SECONDARY OBJECTIVES: I. To evaluate the effect of prandial states and fat content of meals on the safety profile of GDC-0449. II. To describe any anticancer activities of GDC-0449. OUTLINE: Patients are randomized to 1 of 3 treatment arms. ARM I: Patients receive a single dose of vismodegib orally (PO) on an empty stomach. Beginning 7 days later, patients receive vismodegib PO on an empty stomach daily on days 1-28. ARM II: Patients receive a single dose of vismodegib PO after eating a high fat meal. Beginning 7 days later, patients receive vismodegib PO on an empty stomach daily on days 1-28. ARM III: Patients receive a single dose of vismodegib PO after eating a low fat meal. Beginning 7 days later, patients receive vismodegib PO after eating a meal daily on days 1-28. In all arms, treatment repeats every 28 days for 2 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 30 days.
