• International normalized ratio (INR) and activated partial thromboplastin time (aPTT) or partial thromboplastin time (PTT) >1.5 × ULN (unless on therapeutic coagulation).

diastolic >100 mm Hg) or clinically significant (i.e. active)
cardiovascular disease: cerebrovascular accident (CVA)/stroke or myocardial infarction within 6 months prior to first study edication, unstable angina, congestive heart failure (CHF) of New York Heart Association (NYHA) grade II or higher, or serious cardiac arrhythmia requiring medication.
12. Current known infection with HIV, HBV, or HCV.
13. Dyspnea at rest due to complications of advanced malignancy, or other disease requiring continuous oxygen
therapy.
14. Major surgical procedure or significant traumatic injury
within 14 days prior to randomization or anticipation of need
for major surgery during the course of study treatment. Note: Should surgery be necessary during the course of the study, patients should be allowed to recover for a minimum of 14 days prior to subsequent pertuzumab and trastuzumab treatment.
15. Lack of physical integrity of the upper gastrointestinal tract,
clinically significant malabsorption syndrome, or inability to
take oral medication.
16. Receipt of intravenous antibiotics for infection within 7 days prior to randomization.

excipients of recombinant human or humanized antibodies.
19. History of receiving any investigational treatment within 28
days prior to randomization.
20. Concurrent participation in any other therapeutic clinical trial.
21. Assessed by the investigator to be unable or unwilling to
comply with the requirements of the protocol. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is Progression-Free Survival (PFS). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Analysis of PFS will be performed when 165 events have occurred. |
|
E.5.2 | Secondary end point(s) |
The secondary efficacy endpoints are:
- OS
- ORR
- CBR
- Duration of response
- Time to response
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
A first analysis of OS will be performed with the final analysis of PFS. The final analysis of OS will take place once all patients have been followed up for at least 60 months after the last patient is randomized, unless they have been lost to follow-up, withdrawn consent, or died, whichever occurs first. All other secondary endpoints will be summarized with the final analysis of PFS. |
