Keywords: Urothelial carcinoma Urothelial cancer
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 14
Healthy volunteers: no

Brief 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.

Detailed description:
This is a single-arm, open-label study, meaning all patients will be treated in the same fashion with the investigational agent. Scans will be performed every 3 cycles of treatment, and patients will be withdrawn from study in the event of progression or drug intolerance as defined within the protocol.

Treatment will be administered on an outpatient basis. No investigational or commercial agents or therapies other than those described below may be administered with the intent to treat the patient's malignancy.

The length of each cycle is 21 days. For the first cycle of treatment, cabazitaxel will be dosed at 20 mg/m2. During cycle 1, complete blood counts will be performed on days 8 and 15, and dosing on Day 1 cycle 2 will depend upon the nadir counts on those days. If, on toxicity assessment on day 1 of cycle 2, the patient has no residual \>grade 2 toxicity, and all other laboratory parameters are within acceptable limits (see below),at the investigator's discretion the dose can be escalated to 25 mg/m2. 25 mg/m2 is the FDA (Food and Drug Administration)-approved dose for prostate cancer. Neulasta will be given with each dose of cabazitaxel to decrease the risk of febrile neutropenic complication.

Arms:
arm 1: Cabazitaxel following platinum-based chemotherapy

Interventions: intervention 1: Cabazitaxel intervention 2: Neulasta intervention 3: CT Scan intervention 4: Blood Draw
Intervention descriptions: intervention 1: * 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 intervention 2: 6 mg via SQ on Day 2 (24-48 hours post-cabazitaxel) every 21 days intervention 3: CT scan of chest, abdomen, and pelvis to assess disease following every 3rd cycle of treatment (approximately every 9 weeks) intervention 4: 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
