Recruitment & Eligibility

• Status: ot Recruiting
• Sex: All
• Target Recruitment: 100

Inclusion Criteria

1. Patients must have histologically or cytologically confirmed diagnosis of cancer which is not amenable to curative therapy (i.e., advanced and/or metastatic disease).
•Part I (Dose Escalation): Patients with any tumor type or histology may be included.
•Part II (Expansion Cohort): Patients with the following tumor types will be enrolled: malignant melanoma, pancreatic cancer, non small cell lung cancer. If emerging Part I data suggest that a particular tumor type or specific tumor histology might be responsive to treatment, then this tumor type or histology would be considered as preferred disease for inclusion.
2. Prior Therapy :
•The number of prior systemic therapies given for metastatic disease will not be limited (for both Part I and Part II of the study).
3. Age = 18 years.
4. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
5. Life expectancy of =12 weeks.
6. Disease measurability:
•Part I (Dose Escalation): Patients must have a measurable (as per RECIST criteria) and/or evaluable disease (e.g., cytologically or radiologically detectable disease such as ascites, peritoneal deposits, or lesions which do not fulfill RECIST criteria for measurable disease).
•Part II (Expansion Cohort): Patients must have at least one measurable disease lesion as per the RECIST criteria.
7. Patient ability to comply with the collection of tumor biopsies (at baseline, on day 15 of cycle 1, and at the time of disease progression, complete/partial response, or stable disease lasting for more than 4 months) for those eligible for that evaluation (mandatory for part II).
8. Adequate bone marrow function as defined by: ANC of =1.5 x 10 exp9/L, platelet count of =100.0 x 10 exp9/L, and hemoglobin of =9 g/dL.
9. Adequate liver function, as determined by: Serum total bilirubin =1.5 ULN, AST and ALT = 2.5 x ULN (= 5 x ULN if liver metastases); AP < 2.5 x ULN (< 5x ULN if liver metastases). There is no upper limit for alkaline phosphatase (AP) if elevations are due exclusively to bone metastases or if the patient has prostate cancer.
10. Adequate renal function assessed by at least one of the following: 1) Serum creatinine = 1.5 xULN or 2) creatinine clearance estimate of =60 mL/min in male and =50 mL/min in female (as calculated according to Cockroft-Gault formula).
11. Serum calcium (corrected for albumin level) =1.0 x ULN.
12. INR and PTT = 1.5.
13. Signed informed consent.
14. Patient ability to comply with protocol requirements (visits and assessment schedules) and willingness to submit to blood sampling for the PK and PD analyses.
15. Female patients must be postmenopausal (12 months of amenorrhea), surgically sterile or they must agree to use a physical method of contraception. Oral or injectable contraceptive agents can not be the sole method of contraception. Male patients must be surgically sterile or agree to use a barrier method of contraception.
16. Female patients of child-bearing potential must have a negative urine pregnancy test within the seven days prior to the first study drug administration.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

1. Patients with the inability to swallow oral medications or impaired gastrointestinal absorption due to gastrectomy or active inflammatory bowel disease.
2. Patients with known (past or present) Central Nervous System (CNS) metastases.
3. Patients with history of gallbladder disorder or complication including cholelithiasis.
4. Prior chemotherapy, radiotherapy (other than short cycle of palliative radiotherapy for bone pain), or immunotherapy within 28 days of first receipt of study drug (within 6 weeks for nitrosoureas and mitomycin C). Hormone therapy within 14 days of first receipt of study drug, with exception of prostate cancer if indicated.
5. Prior toxicities from chemotherapy or radiotherapy which have not regressed to Grade =1 severity (NCI-CTCAE version 3.0).
6. Prior corticosteroids as anti-cancer therapy within a minimum of 14 days of first receipt of study drug.
7. Treatment with any investigational agent within 28 days of first receipt of study drug.
8. Patients with acute or chronic infection. Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding or any other medical condition that, in the opinion of the investigator, contraindicates the use of an investigational drug, or will impose excessive risk to the patient. Examples of such medical conditions include significant cardiovascular disease (such as NYHA Class III or IV cardiac disease, myocardial infarction within the last 6 months, unstable arrhythmias, or unstable angina) or severe obstructive pulmonary disease .
9. Patients with HIV, HBV and HCV infection.
10. Patients exposed to CYP3A4 inhibitors within 7 days prior to the first dose and CYP3A4 inducers 14 days prior to the first dose (see Appendix°5 table for CYP3A4 inducers and inhibitors).
11. History of any bowel disease including abdominal fistula, gastro-intestinal perforation, and diverticulitis.
12. Major surgery within 28 days of first receipt of study drug.
13. Pregnant or lactating women.
14. Patients with altered mental status or psychiatric disorder that, in the opinion of the investigator, would preclude a valid patient informed consent.
