Acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of the physician, are as follows: Complete abstinence from sexual intercourse for 14 days before exposure to investigational product, through the dosing period, and for at least 21 days after the last dose of investigational product [Hatcher, 2004] Oral contraceptive, either combined or progestogen alone [Hatcher, 2004] Injectable progestogen [Hatcher, 2004] Implants of levonorgestrel [Hatcher, 2004] Estrogenic vaginal ring [Hatcher, 2004] Percutaneous contraceptive patches [Hatcher, 2004] Intrauterine device (IUD) or intrauterine system (IUS) with a documented failure rate of less than 1% per year [Hatcher, 2004]. Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject [Hatcher, 2004]. Double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository) Female subjects who are lactating should discontinue nursing prior to the first dose of study drug and should refrain from nursing throughout the treatment period and for 14 days following the last dose of study drug. |

E.4 | Principal exclusion criteria |
1. Mesenchymal, dedifferentiated, and extraskeletal myxoid chondrosarcoma subtypes 2. Prior malignancy. Note: Subjects who have had another malignancy and have been disease-free for 3 years, or subjects with a history of completely resected non-melanomatous skin carcinoma or successfully treated in situ carcinoma are eligible. 3. History or clinical evidence of central nervous system (CNS) metastases or leptomeningeal carcinomatosis, except for individuals who have previously-treated CNS metastases, are asymptomatic, and have had no requirement for steroids or anti-seizure medication for 6 months prior to first dose of study drug. Screening with CNS imaging studies (computed tomography [CT] or magnetic resonance imaging [MRI]) is required only if clinically indicated or if the subject has a history of CNS metastases. 4. 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, Crohn’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 to beginning study treatment. 5. 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. 6. Presence of uncontrolled infection. 7. Corrected QT interval (QTc) > 480 msecs using Bazett’s formula 8. History of any one or more of the following cardiovascular conditions within the past 6 months: Cardiac angioplasty or stenting Myocardial infarction Unstable angina Coronary artery bypass graft surgery Symptomatic peripheral vascular disease Class III or IV congestive heart failure, as defined by the New York Heart Association (NYHA) [Appendix 5] 9. Poorly controlled hypertension [defined as systolic blood pressure (SBP) of ≥ 140 mmHg or diastolic blood pressure (DBP) of ≥ 90mmHg]. Note: Initiation or adjustment of antihypertensive medication(s) is permitted prior to study entry. BP must be re-assessed on two occasions that are separated by a minimum of 1 hour; on each of these occasions, the mean (of 3 readings) SBP / DBP values from each BP assessment must be < 140/90 mmHg in order for a subject to be eligible for the study (see Section 7.1 for details on BP control and re-assessment prior to study enrollment). 10. History of cerebrovascular accident including transient ischemic attack (TIA), pulmonary embolism or untreated deep venous thrombosis (DVT) within the past 6 months.

Prior major surgery or trauma within 28 days prior to first dose of study drug and/or presence of any non-healing wound, fracture, or ulcer. Major surgery is defined by the use of general anesthesia; however, endoscopic examinations with diagnostic intent are not considered major surgery. Insertion of a vascular access device is exempt from this exclusion criterion. Subjects must have recovered from all surgery-related complications. 12. Evidence of active bleeding or bleeding diathesis. 13. Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels 14. Hemoptysis in excess of 2.5 mL (or one half teaspoon) within 8 weeks of first dose of study drug. 15.
