Cisplatin, Gemcitabine and Bevacizumab in Combination for Metastatic Transitional Cell Cancer
Cisplatin, Gemcitabine and Bevacizumab in Combination for Metastatic Transitional Cell Cancer
Cisplatin is a very important agent for the treatment of TCC as it has a single agent
 response rate of approximately 15%. However, it has been most important as a part of
 combination chemotherapy, MVAC initially and now in combination with gemcitabine. Single
 agent gemcitabine has demonstrated an overall response rate (ORR) of approximately 25%,
 including some complete responses (CR), with minimal toxicity in patients with advanced
 bladder cancer. Bevacizumab, a murine anti-human VEGF monoclonal antibody, has been advanced
 for use in combination with cytotoxic chemotherapy to delay time to disease progression in
 patients with metastatic solid tumors.

 This trial is designed to further assess the efficacy, safety and tolerability of this
 regimen in this patient population.
OUTLINE: This is a multi-center study.

 -  Cisplatin 70 mg/m2 Day 1

 -  Gemcitabine 1250 mg/m2 Day 1 and 8

 -  Bevacizumab 15 mg/kg Day 1

 Review toxicity every cycle (every 3 weeks) Review for radiographic response every 2 cycles
 (every six weeks)

 Progressive disease = off protocol therapy

 Patients will be treated for up to a maximum of 8 cycles of cisplatin and gemcitabine (24
 weeks of therapy). If a patient has not progressed by the end of 24 weeks (completion of
 cisplatin and gemcitabine), then patient will be treated with bevacizumab at 15 mg/kg every
 three weeks for a maximum of 12 months of bevacizumab therapy (since study entry).

 If at any time patient has undue toxicity or progressive disease, patient will be removed
 from the study and followed until progression and for survival.

 If the patient has Grade 3 or 4 neurotoxicity and/or the creatinine rises above 2.0, then the
 cisplatin will be discontinued and the patient continued on study and treated with
 gemcitabine and bevacizumab at the same dose and schedule.

 ECOG Performance Status 0 or 1

 times the upper limit of normal for subjects without evidence of liver metastases.

 Renal:

 -  Serum creatinine of < 1.5 mg/dL.

 -  Urine protein:creatinine ratio < 1.0 at screening

 Cardiovascular:

 -  No history of myocardial infarction or stroke within the last 6 months

 -  No uncontrolled hypertension (blood pressure of >160 systolic and/or 110 diastolic mmHg
 on medication)

 -  No unstable angina, New York Heart Association (NYHA) Grade II or greater congestive
 heart failure

 -  No unstable symptomatic arrhythmia requiring medication (subjects with chronic atrial
 arrhythmia, i.e., atrial fibrillation or paroxysmal supraventricular tachycardia are
 eligible), or clinically significant peripheral vascular disease.

 Pulmonary:

 -  Not specified
Inclusion Criteria:

 -  Previously untreated or relapsed locally advanced or metastatic transitional cell
 carcinoma of the bladder. (Patients with pathology showing ANY component of
 non-transitional cell histology are not eligible).

 -  Relapsed patients may have received prior chemotherapy ≥ one year prior to study
 registration as part of a neoadjuvant or adjuvant regimen and must not have had
 intervening therapy from the end of that treatment until study entry.

 -  Measurable disease as per RECIST.

 -  Prior radiation therapy, immunotherapy, cytokine, biologic or vaccine therapy must be
 greater than 28 days prior to being registered for protocol therapy,

 Exclusion Criteria:

 -  No known central nervous system metastasis. (imaging of brain only required if
 clinically indicated)

 -  No prior organ allograft.

 -  No history of other disease, metabolic dysfunction, physical examination finding, or
 clinical laboratory finding giving reasonable suspicion of a disease or condition that
 contraindicates the use of an investigational drug or that might affect the
 interpretation of the results of the study or render the subject at high risk from
 treatment complications.

 -  No evidence of bleeding diathesis or coagulopathy.

 -  No history of serious, non-healing wound, ulcer or bone fracture

 -  No history of abdominal fistula, gastrointestinal perforation, or intra-abdominal
 abscess within 6 months prior to being registered for protocol therapy.

 -  No prior history of malignancy in the past 5 years with the exception of basal cell
 and squamous cell carcinoma of the skin. Other cancers with low potential for
 metastasis, such as in situ cancers (e.g., Grade 1, TA TCC (low grade superficial
 bladder cancer), colonic polyp with focus of adenocarcinoma) can also be enrolled
 after approval from the study chair.

 -  No major surgical procedure, open biopsy, or significant traumatic injury less than 28
 days prior to being registered for protocol therapy.

 -  Patients are not eligible if the need for any major surgical procedure is anticipated
 during the course of the study.

 -  Any minor surgical procedures, fine needle aspirations or core biopsies must be
 greater than 7 days prior to being registered for protocol therapy except procedures
 to secure a vascular access device which must be greater than 7 days prior to the
 start of protocol therapy.
