Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or females ≥18 years of age;
• Histologically-confirmed advanced (metastatic or unresectable) solid tumor - for which available therapy is not effective;
• ECOG performance status score of ≤2 and an expected survival of >8 weeks;
• Recovered from the toxicities of prior chemotherapy, radiotherapy, and other cancer therapies; all toxicities must be determined to be below Grade 2 (assessed using the NCI CTCAE v4.0).
• Adequate blood counts with a hemoglobin (Hgb) of ≥9.0 mg/dL, absolute neutrophil count (ANC) >1,500/mm3, and platelets ≥100,000/mm3 (all without transfusion support);
• Subjects who are willing and able to provide written informed consent.
• In the expanded cohort at the MTD only: Subjects must be willing to undergo mandatory biopsies of tumor tissue twice during the first cycle (before and during dosing) and must have tumor tissue in a location accessible to incisional biopsy of a superficial lesion or percutaneous core needle biopsy on an outpatient basis without undue risk to the subject.

You may not qualify if…

• Women who are pregnant or breastfeeding;
• Men or women of reproductive potential who are not willing to use acceptable means of contraception while on study drug and for an additional 90 days after the last dose of study drug;
• Body Mass Index (BMI) is ≥30 kg/m2;
• Have primary central nervous system (CNS) tumors or untreated/uncontrolled CNS metastases; Note: Subjects with stable/controlled CNS metastases may be enrolled (i.e., if CNS lesions have been stable in size for at least one month and the subject is off steroid and anti-convulsants).
• Have received any investigational interventional agents within the 4 weeks prior to the start of dosing with ZSTK474;
• Are receiving concurrent anti-tumor chemotherapy, radiotherapy, or immunotherapy - or have received any of these non-investigational agents within the previous 4 weeks or 5-half-lives (whichever is longer) prior to the start of dosing with ZSTK474;
• Are not able or willing to comply with the study procedures, including the study visit schedule;
• Have previously been treated with a phosphatidylinositol 3 kinase (PI3K) inhibitor;
• Have serious or significant intercurrent illnesses or underlying diseases, such as:
• Diabetes
• Gastrointestinal disorder
• Hepatic: AST or ALT >2.5 x ULN (or >5.0 x ULN with liver metastases) or serum bilirubin >1.5 x ULN;
• Renal (acute or chronic renal disease or eGFR <55 mL/min)
• Cardiovascular:
• Uncontrolled hypertension or blood pressure >140/90 mmHg;
• Symptomatic congestive heart failure;
• Myocardial infarction within the past 6 months;
• Unstable angina pectoris;
• Cardiac arrhythmia;
• Congenital long QT syndrome;
• QTc >450 msec for men or >470 msec for women.
• Other:
• Known diagnosis of HIV infection;
• Other ongoing or active infections;
• Psychiatric illness, substance abuse or social situation that would preclude study compliance.
