Pilot Study of Cabazitaxel and Paclitaxel in HER2 Negative Breast Cancer

Phase 2
Recruiting
Conditions
HER2 Negative Metastatic Breast Cancer
Interventions
Registration Number
NCT03048942
Lead Sponsor
University Hospitals Bristol and Weston NHS Foundation Trust
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.

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.

Primary Outcome Measures
NameTimeMethod
Progression free survivalDefined 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
NameTimeMethod
Objective response rateAt 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.

Overall survivalDetermined 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.

Time to next chemotherapy treatmentMeasured 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.

Number of adverse events and Number of participants with adverse events per arm and the grade of AEsForm the date of consent to 30 days after trial treatment has stopped.

CTCAE Version 4.0 graded AEs

Clinical benefit rateAt 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

Time to responseDetermined 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

Quality of life as measured by patients themselvesEQ5D-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
