A Study of BBI503 in Adult Patients With Advanced Urologic Malignancies

Exclusion Criteria

• •Anti-cancer chemotherapy, radiotherapy, immunotherapy, or investigational agents within 7 days of first dose of BBI503. Patients may begin BBI503 on a date determined by the investigator and medical monitor for the sponsor provided there is a minimum of 7 days since last receiving anti-cancer treatment, and that all prior treatment-related adverse events (AEs) have resolved or have been deemed irreversible.
• •Major surgery within 4 weeks prior to first dose (requiring general anesthesia and/or inpatient hospitalization for recovery).
• •Any known symptomatic or untreated brain metastases requiring increase of steroid dose within 2 weeks prior to starting on study. Patients with treated brain metastases must be stable for 4 weeks after completion of that treatment. Post-treatment image documentation of stability is required within 4 months of starting on study. Patients must have no clinical symptoms from brain metastases and must be either off steroids or on a stable dose of steroids for at least 2 weeks prior to protocol enrollment. Patients with known leptomeningeal metastases are excluded, even if treated.
• •Pregnant or breastfeeding
• •Significant gastrointestinal disorder(s), in the opinion of the Principal Investigator, (e.g., Crohn's disease, ulcerative colitis, extensive gastric and small intestine resection)
• •Unable or unwilling to swallow BBI503 capsules daily
• •Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, clinically significant non-healing or healing wounds, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, significant pulmonary disease (shortness of breath at rest or mild exertion), uncontrolled infection or psychiatric illness/social situations that would limit compliance with study requirements (e.g. no reliable transportation).
• •Patients with a history of malignancies other than the tumor of interest except: adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or other solid tumors curatively treated with no evidence of disease for \> 3 years.
• •Abnormal ECGs which are clinically significant such as QT prolongation - QTc \> 480 msec, clinically significant cardiac enlargement or hypertrophy, new bundle branch block, or signs of active ischemia. Patients with evidence of prior infarction who are New York Heart Association (NYHA) functional class II, III, or IV are excluded, as are patients with marked arrhythmia such as Wolff Parkinson White pattern or complete atrioventricular (AV) dissociation.
