Caelyx, Cyclophosphamide and Herceptin in Patients With Metastatic Breast Cancer
- Conditions
- Breast Cancer
- Interventions
- Registration Number
- NCT00258960
- Lead Sponsor
- Spanish Breast Cancer Research Group
- Brief Summary
Eligible patients must receive Caelyx plus Cyclophosphamide plus Herceptin for 6 cycles that will be administered every 4 weeks.
- Detailed Description
Sample size calculation will be done by means of Simon's method in 2 stages for phase II studies and will be based on the principal aim of the study (evaluation of the rate of objective response).
The hypothesis brings over of the efficiency of the treatment it will be accepted if a rate of objective response of at least 55 % is obtained, rejecting the efficiency of the treatment when the rate of response targets be lower than 35 %. In this case, considering an alpha error of 0.05 and 80 % power, 14 patients will be included in the first stage; the study would continue if more than 5 objective responses were found. The total number of patients to including in the study would be 44. The results will be significant if they find at least 20 objective responses.
Assuming a drop-out rate of 10 %, the total number of patients needed is 49 patients.

- Primary Outcome Measures
Name Time Method Objective Response Rate (ORR) Up to cycle 6 (24 weeks) ORR is the sum of the Complete Responses (CR) and Partial Responses (PR) according to the RECIST criteria, experienced for each patient during treatment (recorded from the start of the treatment until disease progression). Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT scan (computed tomography) or MRI (magnetic resonance imaging): Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response Rate (ORR) = CR + PR.
- Secondary Outcome Measures
Name Time Method Response Duration Through study treatment, and follow up period, assessed up to 88 weeks Response duration was defined as the time elapsed from the first evidence of tumor response (Complete response or Partial Response) until clinical evidence of disease progression or death occurred.
Overall Survival (OS) Through study treatment, and follow up period, assessed up to 88 weeks OS was defined as the time elapsed from first treatment until death from any cause.
Time to Progression (TTP) Through study treatment, and follow up period, assessed up to 88 weeks TTP was defined as the time elapsed from first treatment until clinical evidence of disease progression. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions
Time to Treatment Failure (TTF) Through study treatment, and follow up period, assessed up to 88 weeks TTF was defined as the time elapsed from first treatment until patient discontinuation due to toxicity, disease progression, death or withdrawal of consent for any reason, whichever occurred first.
