[6b] Unstable angina or myocardial infarction within 6 months of
enrolment,
[6c] Serious and potentially life-threatening arrhythmia.
[7] Subjects with a high probability of Long QT syndrome, or QTc
interval prolongation of more than or equal to 501 msec on at least two separate ECGs, following correction of any electrolyte imbalance.
[8] Subjects with known central nervous system metastases.
[9] Any serious concomitant illness or infectious disease requiring
treatment, or infectious disease not requiring treatment, but with
significant risks for myelosuppressive complications associated with chemotherapy.
[10] Any malignancy that required treatment, or has shown evidence of recurrence (except for soft tissue sarcoma, non-melanoma skin cancer, or histologically confirmed complete excision of carcinoma in situ) during the 5 years prior to randomization.
[11] Female subjects must not be pregnant as documented by a negative beta-human chorionic gonadotropin (ß-hCG) test with a minimum sensitivity 25 IU/L or equivalent unit of ß-hCG at Screening and Baseline, or breastfeeding.

E.5 End points |
E.5.1 | Primary end point(s) |
Overall survival, measured from the date of randomization until date of death from any cause. Subjects who are lost to follow-up and the subjects who are alive at the date of data cut-off will be censored at the date the subject was last known alive. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
When the target number of events (estimated to be 353 deaths) has been observed |
|
E.5.2 | Secondary end point(s) |
[1] Progression-free survival, defined as the time from the date of
randomization to the date of first documentation of disease progression, or date of death (whichever occurs first). Progression free survival censoring rules will apply, and will be defined in the SAP.
[2] Progression-free rate at Week 12, defined as the proportion of subjects alive and progression-free at 12 weeks from the date of randomization.
[3] Clinical Benefit Rate, the proportion of subjects who have best overall response of CR or PR or dSD. |
