Brief Summary:
A study for patients with confirmed locally advanced or metastatic Transitional Cell Carcinoma of the bladder or upper urinary tracts who have developed progressive disease within 12 months of their platinum based chemotherapy. The study aims to compare the overall response rate of cabazitaxel treatment versus best supportive care including single agent chemotherapy.

Condition or disease Intervention/treatment Phase
Transitional Cell Carcinoma Drug: Cabazitaxel Other: Best Supportive Care Phase 2 Phase 3

Detailed Description:

Bladder cancer was the 9th most common cause of cancer worldwide in 2002. About 70% of patients have superficial tumour and 30% have invasive tumour at diagnosis. Patients with superficial tumour are treated by surgery, which is the only curative treatment. However, about 50% of these patients will relapse, and cannot be cured by local treatment in the majority of cases. The survival of untreated metastatic patients does not exceed 3 to 6 months, and systemic chemotherapy increases overall survival of patients with unresectable disease.

However, the overall survival of patients with advanced disease treated with chemotherapy remains short (14 months), which reflects a substantial unmet medical need for more effective therapy in this very poor prognosis disease.

Cabazitaxel is a new taxane, taxanes have demonstrated activity in advanced bladder cancer, and are among the most active new cytotoxic agents to be assessed in transitional cell carcinoma.

Cabazitaxel has demonstrated activity in cell lines with acquired resistance to doxorubicin, vincristine, vinblastine, paclitaxel, and docetaxel.

This is a randomised, open-label, parallel-group phase 2 study of cabazitaxel versus best supportive care (including chemotherapy).

The study is divided into three phases: screening, treatment, and follow-up. The treatment phase comprises a maximum of six three-weekly cycles of therapy, with a post treatment discontinuation visit taking place 3 weeks after last dose of treatment before the follow-up phase begins.

This phase 2 study will initially recruit 25 patients and after interim analysis will to increase to recruit 96 patients randomised between the two treatment options and the study is expected to last about 2 years.

Best Supportive Care including single agent chemotherapy as determined by the patient's study physician

Primary Outcome Measures :
  1. Overall response rate [ Time Frame: Change from baseline at Week 9 and Week 18 ]
    To compare the overall response rate of patients administered cabazitaxel vs best supportive care (including single agent chemotherapy) in patients with transitional cell carcinoma who have previously progressed on a platinum-based regimen.

Secondary Outcome Measures :
  1. Overall survival [ Time Frame: From date of randomisation to the date of tumour progression or death (from any cause) (or survival at study cut-off date), whichever came first up to 12months after the final patient has completed study treatment ]
    Defined as the time interval from the date of randomization to the date of death due to any cause. In absence of confirmation of death, survival time will be censored at the earlier of the last date the patient is known to be alive and the study cut-off date.

  2. Quality of Life [ Time Frame: Change from baseline at Week 6, Week 12, Week 18, Week 21 ]
    QOL will be assessed by using a validated instrument; the EuroQOL (EQ-5D).

  3. Safety and tolerability [ Time Frame: From date of randomisation up to 30 days after final dose of study medication ]
    Dose delays and dose reductions, adverse events, laboratory safety data

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Written informed consent
  • Age ≥ 18
  • Life expectancy ≥ 12 weeks
  • Patients with histology/cytology confirmed Transitional Cell Carcinoma (TCC) including mixed pathology with predominantly TCC, with locally advanced (T4b) or metastatic (lymph node or visceral) TCC arising from bladder or upper urinary tracts.
  • Treated patients with incidental prostate cancer (pT2, Gleason ≤ 6) and PSA (Prostate Specific Antigen) ≤ 0.5 ng/mL are eligible
  • Measurable disease as per RECIST Criteria 1.1
  • ECOG Performance Status 0-1.
  • Previously received first line platinum based treatment.
  • Recurrence within 12 months (by RECIST criteria version 1.1) from last cycle of chemotherapy.

Exclusion Criteria:

  • Previous therapy with a taxane.
  • Pure non TCC histologies
  • Grade II or more peripheral neuropathy
  • Prior surgery, radiation, chemotherapy, or other anti-cancer therapy within 4 weeks prior to enrolment in the study.

    • Total bilirubin > 1.0 x ULN,
    • Serum creatinine > 1.5 x ULN. If creatinine 1.0 - 1.5 x ULN, creatinine clearance will be calculated according to CKD-EPI formula and patients with creatinine clearance ≤ 30 mL/min should be excluded (see Appendix 6 for formula)
