July 4, 2016 updated by: Sanofi

A Phase IV, Multicenter, National, Non-comparative, Open-label Study of Cabazitaxel, Combined With Prednisone and Prophylaxis of Neutropenia Complications in the Second-line Treatment of Patients With Metastatic Castration-resistant Prostate Cancer and After Failure of Docetaxel-based Chemotherapy. Descriptive Assessment of the Circulating Tumor Cells in This Context.

Primary Objective:

Secondary Objectives:

  • PSA response rate;
  • Descriptive assessment of CTC (circulating Tumor Cells);
  • Rates of grade ≥ 3 neutropenia and febrile neutropenia and grade ≥3 diarrhea over the treatment period;
  • Description of the Health Quality of Life of the patients;

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion criteria :

  • Histologically proven Castration-Resistant Prostate Cancer (stage IV only);
  • Prior failure of treatment with docetaxel; o Documentation of metastasis by imaging.
  • Performance status 0 or 1;

Exclusion criteria:

  • Previous treatment with chemotherapy, except for docetaxel;
  • Previous use of abiraterone;
  • Inability to maintain treatment with androgen deprivation if no previous history of orchiectomy;
  • Presence of any other active malignancy or history of any tumor diagnosed in the last 5 years, except basal cell or squamous cell carcinoma of the skin or in situ carcinoma of the skin, bladder or anal canal (these tumors do not prevent participation if they have been treated, even in the last 5 years);
  • Hypersensitivity or known allergy to any of the treatments under study, including history of severe hypersensitivity reaction (≥grade 3) to docetaxel and/or to polysorbate 80 containing drugs
  • History of congestive heart failure or myocardial infarction within the last 6 months, or uncontrolled cardiac arrhythmias, angina pectoris or uncontrolled hypertension;
  • Uncontrolled severe illness or medical condition (including uncontrolled diabetes mellitus)
  • Presence of severe comorbidity, which in the opinion of the investigator, puts the patient at risk or impairs compliance to the protocol;
  • Known seropositivity for HIV;
  • Presence of significant psychiatric or neurological disease, in the investigator's opinion;
  • Presence of uncontrolled hypercalcemia;
  • Refusal to use appropriate contraception during the study period;
  • Participation in any clinical trial in the last 12 months, unless there is benefit to the patient to be justified by the principal investigator
  • Concurrent or planned treatment with strong inhibitors or strong inducers of cytochrome P450 3A4/5
  • Inadequate organ and bone marrow function
