Treatment Compliance3 yearsEvaluate treatment compliance rate in both treatment arms, in order to analyze it, the dose intensity would be calculated as the quantity of each of the administered study drugs per unit of time (mg/m2/week) regardless of the treatment arm. To analyze the relative dose intensity, the dose of each administered drug will be divided per a unit of time and the planned quantity of each drug according to the doses described in the protocol.

Outcome results

Primary

Progression Free Survival (PFS)

The primary endpoint was to select the most effective treatment arm based on the progression-free survival (PFS) reached in each treatment arm. This was defined as the time elapsed from inclusion in the study until the date when disease progression or death (for any cause) was documented.

Time frame: Through study completion. The study was prematurely closed at 19 months due to lack of accrual. The primary endopoint was not analyzed.

Population: Only 17 patients out of a planned protocol number of 80 were recruited to the study, owing to premature closure of the study. Two of those patients did not meet some of the inclusion and/or exclusion criteria. Database lock: 3 June 2013. There were insufficient numbers of patients to be able to analyse the efficacy endpoints.~The possible discrepancies that were pending resolution have been closed as Premature closure of the study. Deviation DN13/024.~.
