Examples of adequate contraceptive measures are an intra-uterine device, a barrier method (condoms, diaphragm) in conjunction with spermicidal jelly, or total abstinence. Oral, injectable, or implant hormonal contraceptives are not acceptable for females participating in the study.

Safety endpoints are the primary objectives in this study and will include: all AEs, Grade ≥3 AEs, SAEs, AEs leading to premature discontinuation of study treatment, AEs causing interruption of trastuzumab SC, cardiac AEs, CHF-related SAEs, premature withdrawals from study and study medication, exposure to treatment, laboratory parameters, LVEF, vital signs, ECG, weight, and ECOG performance status. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary analysis of the safety endpoints will take place when all patients have received 18 cycles of trastuzumab SC and have completed the Safety Follow-up assessments (4 weeks after their last dose of study treatment). |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy endpoints include DFS, OS (both cohorts) and patients’ satisfaction with trastuzumab SC administration using the SID (Cohort B patients who went on to self administration only). |
|

A preliminary analysis of DFS and OS will be undertaken at the time of the primary safety analysis, i.e. when all patients have received 18 cycles of trastuzumab SC and have completed the Safety Follow-up assessments (4 weeks after their last dose of study treatment). The final analysis of OS and DFS will take place when the last patient has been followed up for at least 24 months after her/his last study treatment, or earlier, if one of the following is documented for all treated patients: withdrawal of consent, loss to follow-up or death. |
