Cabazitaxel in Patients With Urothelial Carcinoma Who Have Disease Progression Following Platinum-Based Chemotherapy
Condition: Urothelial Carcinoma
MeSH terms: Carcinoma; Carcinoma, Transitional Cell; Disease Progression
Intervention: Cabazitaxel; Neulasta; CT Scan; Blood Draw
Intervention description: Cycle 1: 20 mg/m2 in 250cc NS via IV on Day 1 every 21 days
Following cycles: 20 mg/m2 or escalated to 25 mg/m2 or reduced by 5 mg/m2 in 250cc NS via IV on Day 1 every 21 days at investigator's discretion
Treatment continues until disease progression, intercurrent illness preventing further treatment, unacceptable adverse event(s), patient withdraws from the study, or changes in the patient's condition which render further treatment unacceptable in the judgment of the investigator; 6 mg via SQ on Day 2 (24-48 hours post-cabazitaxel) every 21 days; CT scan of chest, abdomen, and pelvis to assess disease following every 3rd cycle of treatment (approximately every 9 weeks); Approximately 2 tablespoons of blood will be taken to test complete blood count, glucose, hematology, electrolytes, liver function, creatinine clearance, and a chemistry profile. This week be done weekly during the first cycle of treatment

Summary:

      There is no accepted standard chemotherapy approved for use in the second line for patients
      with advanced urothelial carcinoma whose cancer has progressed on combination chemotherapy
      including either cisplatin or carboplatin. The chemotherapy class called taxanes, either as
      single agents or in combination, have demonstrated modest efficacy in small studies.
      Cabazitaxel is an agent in the taxane family designed to be active in the setting of acquired
      multi-drug resistance that arises in some tumors. The objective of this study is to evaluate
      the safety and efficacy of this agent in patients with urothelial carcinoma refractory
      compared to combination platinum based chemotherapy.
