General information about the trial
|
|||
Main objective of the trial |
To assess non-inferiority in terms of time to progression within one year of capecitabine treatment group in continuous administration versus capecitabine treatment group in standard administration.
|
||
Protection of trial subjects |
Each patient was monitored on a regular basis in order to detect potential adverse events. Before each cycle administration was evaluated white cell count, neutrophils/granulocytes, hemoglobin and platelet count, total bilirubin, GOT/GPT, alkaline phosphatase total protein, clearance of creatinine (calculated), serum creatinine and also physical examination and functional status (ECOG).
|
||
Background therapy |
The approved capecitabine regimen in monotherapy in metastatic breast cancer is 1,250 mg/m2 twice daily, two weeks on one week off. Dose modifications are often required due to appearance of severehand-foot syndrome. We tested a continuous regimen with lower daily dose but similar cumulative dose trying to reduce the severity of adverse events maintaining the efficacy | ||

Recruitment
|
||||||||||||||||
Recruitment details |
Between November 2004 and August 2010, 195 patients were randomly assigned to Cint (97) and Ccont (98) in 13 GEICAM sites in Spain. Three patients never received treatment, leaving 192 for ITT analysis (95 Cint; 97 Ccont); 5 patients in each treatment arm had major protocol violations, leaving 182 PP evaluable patients. | |||||||||||||||
Pre-assignment
|
||||||||||||||||
Screening details |
To be eligible, patients had to be over age 18, have confirmed histologicaladenocarcinoma of the breast that was metastatic or inoperable locally advanced and negative for HER2/neu overexpression. Patients were excluded if they had prior severe reactions or hypersensitivity to fluoropyrimidines. | |||||||||||||||

If a patient did not progresses or dies due to PD during the treatment but she receives an antitumoral treatment, after the end of the study treatment, it is censored.

Non-Inferiority | ||||||||||||
Statistical analysis description |
If we assume that the non-inferiority level is up to 15% lower (equivalent to a median progression-free time of 3 months), for a one-sided error α=0.05, and 80% power, are necessary 88 patients per group.
Considering an dropout rate of around 10%, the number of patients would be 98 per group.

dies for any reason.
If a patient did not progresses or dies during the treatment but she receives an antitumoral treatment,
after the end of the study treatment, it is censored. The censoring date is the first follow up date when
she receives the antitumoral treament. In this case, the time from the moment the patient starts the

Substantial protocol amendments (globally) |

Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
24 Oct 2007 |
- Reorder the primary and secondary objectives of the study.
- Modify the sample size calculation according to the new main valuation variable.
- Extend the recruitment period to include sufficient number of patients according to the new sample size.
- Modify the evaluation methods according to these objectives.
- Rework the statistical analysis section |
||
26 May 2008 |
- To clarify some of the inclusion and exclusion criteria. The suggested changes do not substantially change the population under test.
- Expand the use of bisphosphonates and corticosteroids in patients with bone metastases.
- Update the toxicity coding system from the NCI v 2.0 system to NCI 3.0.
- To add a new secondary objective: to evaluate the relationship between enzyme polymorphisms related to the metabolism of Capecitabine, and its toxicity and efficacy.
- Addition of two new sites
- Clarify some aspects of the protocol that may give rise to erroneous interpretations; such as, for example, the section referring to the Xeloda dose reduction guidelines in the event of the adverse effect of Palmar-plantar erythrodysesthesia syndrome. |
||
26 Feb 2010 |
Increase sample size: The primary objective was based on obtaining 88 evaluable patients per group, total 176, not including any prediction of losses. Based on the fact that the usual percentage of losses in metastatic studies is approximately 10%, it is intended to increase the number of expected subjects to 196 recruited patients to finally obtain the 176 evaluable patients. |
||
23 Sep 2011 |
- Incorporation of a Secondary Objective: The magnitude of the progression-free survival rate at one year is a reasonably important objective, given its behavior as a predictor of overall survival in patients with breast cancer.
- Modification in the definitions of Population and Efficacy: The variables of time to an event or survival times are widely used variables in the field of cancer treatment, however, some scientific publications show discrepancies in the definitions of these variables in different clinical trials which can lead to difficulties in interpreting their results and comparability between trials. The objective of this amendment is to standardize the terminology according to the definitions contemplated by the regulatory agencies. |
||
Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
None reported | |||
