This is an interventional treatment trial for Bladder Cancer focused on measuring Advanced/Metastatic Bladder Carcinoma Read More

Inclusion Criteria:

• Histologic documentation of diagnosis of transitional cell carcinoma of the bladder, urethra, ureter, or renal pelvis
• Unresectable, locally advanced or metastatic disease
• CrCl ≥ 60 ml/min or serum creatinine < 1.5
• ≥ 4 weeks since prior RT
• ECOG Performance Status of 0 or 1 (Appendix I)
• Age ≥ 18 years of age
• Women of childbearing potential and men must agree to use adequate contraception (barrier method of birth control) prior to study entry and for the duration of study participation. Men and women should use adequate birth control for at least 2 weeks after the last administration of sorafenib.
• Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment
• Ability to understand and the willingness to sign a written informed consent. A signed informed consent must be obtained prior to any study specific procedures.

• Adequate bone marrow, liver and renal function as assessed by the following:

  • Hemoglobin > 9.0 g/dl
  • Absolute neutrophil count (ANC) ≥ 1,500/mm3
  • Platelet count ≥ 100,000/mm3
  • Total bilirubin ≤ 1.5 times ULN
• ALT and AST ≤ 2.5 times the ULN ( ≤ 5 x ULN for patients with liver involvement)
• INR < 1.5 or a PT/PTT within normal limits. Patients receiving anti-coagulation treatment with an agent such as warfarin or heparin may be allowed to participate. For patients on warfarin, the INR should be measured prior to initiation of sorafenib and monitored at least weekly, or as defined by the local standard of care, until INR is stable.

• History of stroke within six months
• Clinically significant peripheral vascular disease
• Known brain metastasis. Patients with neurological symptoms must undergo a CT scan/MRI of the brain to exclude brain metastasis.
• Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy.
• Uncontrolled hypertension defined as systolic blood pressure > 150 mmHg or diastolic pressure > 90 mmHg, despite optimal medical management.
• Sorafenib is contraindicated in patients with known severe hypersensitivity to sorafenib or any of the excipients.
• Known human immunodeficiency virus (HIV) infection or chronic Hepatitis B or C.
• Active clinically serious infection > CTCAE Grade 2.
