Summary

26 patients with invasive primary transitional cell carcinoma of the bladder will receive 4 cycles of combination chemotherapy consisting of Cabazitaxel and Cisplatin both given intravenously on day 1 of each 3 weekly cycle prior to radical cystectomy, to evaluate the overall response rate and to determine whether this approach warrants further research of a phase II/III study.Participation in 2 sub studies will also be offered to the participants. 1. Contrast Magnetic resonance imaging (MRI ) scans will be taken at baseline and after cycle 1 and cycle 3. 2. A pilot sub study involving the circulating tumour cell concentration from blood samples taken at baseline, prior to each cycle of chemotherapy and prior to surgery

Eligibility Criteria

Inclusion Criteria

  • Glomerular filtration rate (GFR) ≥60ml/min.
  • Written, informed consent

Exclusion Criteria

  • ECOG Performance Status ≥ 2
  • Lymph node involvement or metastatic disease
  • Prior surgery (except transurethral resection of bladder tumour), radiation, chemotherapy, or other anti-cancer therapy within 4 weeks prior to enrolment
  • Active Grade ≥2 peripheral neuropathy
  • Active secondary cancers
  • History of severe hypersensitivity reaction (≥Grade 3) to polysorbate 80 containing drugs
  • Other concurrent serious illness or medical conditions
  • Inadequate organ function as evidenced by peripheral blood counts at enrolment:
  • Electrocardiogram (ECG) evidence of uncontrolled cardiac arrhythmias, angina pectoris, and/or hypertension, history of congestive heart failure, or myocardial infarction within last 6 months.
  • Uncontrolled diabetes mellitus.
