Inclusion Criteria:

1. Subjects must provide written informed consent prior to performance of study-specific procedures or assessments and must be willing to comply with treatment and follow up.
2. Patients with advanced or metastatic solid tumors that are refractory to standard therapy, relapsed after standard therapy, or who have no standard therapy available that improves survival by at least three months.
3. Patients must have been off previous chemotherapy or radiotherapy for two weeks prior to start of treatment. For biologic/targeted therapies, patients must be >/= five half-lives or >/= 2 weeks from the last treatment dose, whichever comes first. Patients may have received palliative localized radiation immediately before (or during) treatment provided radiation is not delivered to the single target lesion available.
4. ECOG performance status </= 2.
5. Abnormal organ function is permitted. However, patients must meet the following criteria: neutrophil count >/= 1.5 x 10*9/L; platelets >/= 100 x 10*9/L; creatinine </= 1.5 X ULN; T. bilirubin </= 1.5 X ULN; AST(SGOT) and/or ALT(SGPT) </= 2.5 X ULN, UPC < 1.
6. Women of child-bearing potential MUST have a negative serum or urine HCG test within 14 days of first dose. Sexually active patients must agree to use contraception for the duration of study participation: women, 2 weeks before the first treatment dose and for 28 days after the last dose; and men, from the first treatment dose and for 28 days after the last dose of treatment. For the purpose of this protocol women of child-bearing potential are defined as: a female able to have children that has not been surgically sterilized or that has not been without menses for 12 consecutive months.
7. Patients must be >/=16 years of age.
8. Fresh blood samples must be provided for all subjects for biomarker analysis before treatment with investigational product.
9. Patients must have evaluable disease by RECIST criteria.
10. For the dose expansion cohort patients will have to have either PI3K mutations and/or PTEN loss and/or PTEN mutation of their tumor.

Exclusion Criteria:

1. Central nervous system (CNS) metastases at baseline, with the exception of those subjects who have previously-treated CNS metastases (surgery +/- radiotherapy, radiosurgery, or gamma knife) and who meet both of the following criteria: a) are asymptomatic and b) have no requirement for steroids or enzyme-inducing anti-convulsants in prior 2 weeks.
2. Clinically significant gastrointestinal abnormalities that may increase the risk for gastrointestinal bleeding including, but not limited to:Active peptic ulcer disease; Known intraluminal metastatic lesion/s with risk of bleeding; Inflammatory bowel disease (e.g. ulcerative colitis, Chrohn's disease),or other gastrointestinal conditions with increased risk of perforation; History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 28 days prior beginning study treatment.
3. Clinically significant gastrointestinal abnormalities that may affect absorption of investigational product including, but not limited to; Malabsorption syndrome; Major resection of the stomach or small bowel
4. Corrected QT (QTc) > 480 msecs.
5. History of any one or more of the following cardiovascular conditions within the past 6 months:Cerebrovascular accident, Myocardial infarction, Unstable angina , Cardiac angioplasty or stenting, Coronary artery bypass graft surgery, Class III or IV heart failure, as defined by the New York Heart Association (NYHA), Untreated pulmonary embolism (PE) or deep venous thrombosis (DVT). Note: subjects with recent PE or DVT who have been therapeutically coagulated for at least 6 weeks are eligible.
6. Uncontrolled systemic vascular hypertension (systolic blood pressure >/= 140 mmHg, diastolic blood pressure >/= 90 mmHg). Note: Initiation or adjustment of antihypertensive medication(s) is permitted prior to study entry. Following antihypertensive medication initiation or adjustment, blood pressure (BP) must be re-assessed three times at approximately 2-minute intervals. At least 24 hours must have elapsed between anti-hypertensive medication initiation or adjustment and BP measurement. These three values should be averaged to obtain the mean diastolic BP and mean systolic BP. The mean SBP/DBP ration must be < 140/90.
7. Major surgery or trauma within 28 days prior to first dose of investigational product and/or presence of any non-healing wound, fracture, or ulcer (procedures such as catheter placement not considered to be major surgery).
8. Evidence of active bleeding or bleeding diathesis.
9. Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels that increase the risk of pulmonary hemorrhage. Note: Lesions infiltrating major pulmonary vessels (contiguous tumor and vessels) are excluded; however, the presence of a tumor that is touching, but not infiltrating (abutting) the vessels is acceptable (CT with contrast is strongly recommended to evaluate such lesions). Large protruding endobronchial lesions in the main or lobar bronchi are excluded; however, endobronchial lesions in the segmented bronchi are allowed. Lesions extensively infiltrating the main or lobar bronchi are excluded; however, minor infiltrations in the wall of the bronchi are allowed.
10. Recent hemoptysis (>/= ½ teaspoon of red blood within 8 weeks before first dose of study drug).
11. Any serious and/or unstable pre-existing medical, psychiatric, or other condition that could interfere with subject's safety, provision of informed consent, or compliance to study procedures.
12. Administration of any non-oncologic investigational drug within 30 days or 5 half lives whichever is longer prior to receiving the first dose of study treatment.
13. Any ongoing toxicity from prior anti-cancer therapy that is >Grade 1 and/or that is progressing in severity, except alopecia.
14. Prior malignancy Note: Subjects who have had another malignancy and have been disease-free for 2 years, and/or subjects with a history of completely resected non-melanomatous skin carcinoma or successfully treated in situ carcinoma are eligible.
