Study Description

Brief Summary:
90 patients with HER2 negative breast cancer will be randomised to receive 18 weeks of chemotherapy treatment, either 6 cycles of 3 weekly Cabazitaxel or 6 cycles of weekly Paclitaxel to determine the difference in progression free survival between the 2 groups. If results at that stage suggest a potential benefit then the trial will be developed further to accrue 70 more patients.

Condition or disease Intervention/treatment Phase
HER2 Negative Metastatic Breast Cancer Drug: Cabazitaxel Drug: Paclitaxel Phase 2

Detailed Description:
This is a prospective multicentre, randomised, open label, study comparing the efficacy and the safety of six 3-weekly cycles cabazitaxel versus 18 x weekly paclitaxel given as first line chemotherapy treatment in patients with HER2-normal metastatic breast cancer. Randomisation will be conducted by a 1:1 ratio.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Progression free survival [ Time Frame: Defined as the time from randomisation to either disease progression or death from any cause, whichever came first, assessed up to 5 years. ]
    Duration of progression free survival


Secondary Outcome Measures :
  1. Clinical benefit rate [ Time Frame: At the completion of 6 cycles of chemotherapy, which is after 18 weeks ]
    Defined as stable disease rate + partial response rate+complete response rate according to RECIST 1.1 criteria

  2. Objective response rate [ Time Frame: At completion of 6 cycles of chemotherapy, which is after 18 weeks. ]
    Defined as complete and partial response recorded from the start of treatment to completion of 6 cycles of treatment.

  3. Overall survival [ Time Frame: Determined as the time from randomisation to death from any cause. Average survival rates for this population may be approximately 18 months. ]
    Survival duration from randomisation to date of death.

  4. Time to next chemotherapy treatment [ Time Frame: Measured from from the date of the last day of trial treatment. approximately after progression which on average would be after 12 months. ]
    time from randomisation to another chemotherapy treatment after confirmed progression.

  5. Time to response [ Time Frame: Determined by time from randomisation to radiological partial response, usually within the 6 cycles of treatment, therefore wihtin 18 weeks. ]
    Time taken for tumour burden to respond to treatment

  6. Quality of life as measured by patients themselves [ Time Frame: EQ5D-5L and FACT B will be completed at baseline, prior to cycles 3 and 5 and at the end of treatment visit, therefore within approximately 21 weeks from randomisation ]
    2 Quality of life questionnaires

  7. Number of adverse events and Number of participants with adverse events per arm and the grade of AEs [ Time Frame: Form the date of consent to 30 days after trial treatment has stopped. ]
    CTCAE Version 4.0 graded AEs
