Brief Summary:
Cabazitaxel is already approved by the Food and Drug Administration (FDA) for use in patients with advanced prostrate cancer, following docetaxel therapy. The purpose of this study is to better understand the response and toxicity of cabazitaxel of elderly men (age 75 years and older) with advanced prostate cancer who have progressed during or after treatment with docetaxel. All patients on this study will receive cabazitaxel by intravenous (through a vein) infusion plus prednisone by mouth twice daily, and following the chemotherapy infusions, an injection of a granulocyte colony-stimulating factor (G-CSF). G-CSF will help the body produce more white blood cells, which should help decrease the risk of getting an infection while being treated with cabazitaxel.

Condition or disease Intervention/treatment Phase
Castrate-resistant Metastatic Prostate Cancer Drug: Cabazitaxel Drug: Prednisone Drug: Granulocyte colony-stimulating factor (G-CSF) Phase 2

Detailed Description:

This is a single arm, open label, phase II trial of cabazitaxel every 3 weeks in patients who are ≥ 75 years of age with castration-resistant, metastatic prostate cancer who have progressed during or after docetaxel.

Primary objective:

-The primary objective is to determine the efficacy of cabazitaxel in men 75 years of age or older with castration-resistant, metastatic prostate cancer who have progressed during of following treatment with docetaxel.

Secondary objectives:

  • To characterize the safety and tolerability of cabazitaxel in patients ≥ 75 years of age
  • To determine the PSA response
  • To determine the effect of cabazitaxel on functional status using geriatric assessments

Exploratory objectives:

  • Determine the effect of therapy with cabazitaxel on the number of circulating tumor cells (CTC)
  • To measure the effects of cabazitaxel on apoptosis in CTCs from patients ≥ 75 years of age using H2AX and M30 as biomarkers.
  • To determine the relationship between geriatric-focused assessment of comorbidity and functional ability and toxicity and response.

Patients will receive cabazitaxel 25 mg/m2 every 3 weeks with 10 mg prednisone daily until progression, intolerance of therapy, or withdrawal of consent. Patients will receive granulocyte colony stimulating factor (Neulasta 6 mg sc) with each cycle, starting with the first cycle, to minimize the risk of complications from neutropenia. Patients will be followed for 28 days after discontinuation of therapy or death, whichever occurs first. Patients with serious adverse events at the time of removal from the trial will be followed until the toxicities resolve or are deemed irreversible by the treating physician.

  • XRP6258

Drug: Prednisone
Prednisone 10 mg on Day 1 of the first cycle and continue taking 10 mg po daily for the entire cycle.

Drug: Granulocyte colony-stimulating factor (G-CSF)
Granulocyte colony stimulating factor (Neulasta 6 mg sc) with each cycle, starting with the first cycle, to minimize the risk of complications from neutropenia.

Primary Outcome Measures :
  1. Number of patients progression-free survival after completion of treatment. [ Time Frame: at end of treatment (up to 30 weeks) ]
    Treatment will continue until disease progression, intolerable side effects, or a maximum of 10 cycles of therapy. Progression-free survival defined as PSA progression, tumor progression in patients with measurable disease, or death.

Secondary Outcome Measures :
  1. Number of patients that experience treatment-emergent adverse events [ Time Frame: at end of each treatment cycle (up to 30 weeks) ]
    The assessment of safety will be based on the frequency and severity of adverse events. The incidence of treatment-emergent adverse events will be summarized by organ system, severity based on CTCAE (Common Terminology Criteria for Adverse Events) version 4.02, and relation to study drug by dose cohort. Adverse events assessed after each treatment cycle.

  2. Number of patients with a prostate-specific antigen (PSA) response [ Time Frame: at end of each treatment cycle (up to 30 weeks) ]
    PSA response defined as a 50% or more reduction in serum PSA concentration in patients with a serum PSA concentration of 20 μg/L or more at baseline and confirmed with a repeat PSA measurement after at least 3 weeks.

  3. Change in geriatric assessments from baseline to end of therapy [ Time Frame: every 2 cycles of therapy (6 weeks) up to 30 weeks ]
    Geriatric assessment to determine the relationship between functional ability or comorbidity and treatment response or toxicity. Patients will be have a geriatric assessment which will included a range of assessments, such as the Mini Mental Status Exam, Get Up and Go test, and the Geriatric Depression Scale, at baseline and after every 2 cycles of therapy.

Other Outcome Measures:
  1. Change in circulating tumor cells (CTC) from baseline [ Time Frame: at end of treatment (up to 30 weeks) ]
    Number of CTC at baseline and after treatment with cabazitaxel

  2. Change in biomarkers from baseline [ Time Frame: at 3 weeks (after one cycle) ]
    Level H2AX and M30 in CTCs at baseline and after treatment with cabazitaxel
