E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Part 1: Safety Run-in Phase
The primary objective for Part 1 of this study is as follows:
-To determine the safety and tolerability of pertuzumab in combination with either topotecan or paclitaxel.
Part 2:
The primary objective for Part 2 of this study is as follows:
-To determine if pertuzumab plus chemotherapy is superior to placebo plus chemotherapy as measured by progression-free survival (PFS) assessed by a blinded independent review committee (IRC). |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective for Part 1 of this study is as follows:
-To descriptively evaluate the progression-free survival (PFS; assessed by investigator) of pertuzumab in combination with either topotecan or paclitaxel.
The secondary objectives for Part 2 of this study are as follows:
-To determine if pertuzumab plus chemotherapy is superior to placebo plus chemotherapy with respect to:
-Overall survival (OS; key secondary endpoint).
-PFS assessed by investigator.
-Objective response rate (ORR).
-Safety and tolerability including incidence of anti-therapeutic antibodies to pertuzumab.

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
PK substudy. Assuming that topotecan is used in Part 2 of the trial, a subset of sites capable of handling PK sampling and patients who receive topotecan will participate in a PK and drug–drug interaction substudy. Separate Informed Consent Form will be required for participation in the PK substudy (up to approximately 51 patients).
Integrated in updated Protocol Version 3.
Objectives:
-To characterize the PK of pertuzumab in patients with epithelial ovarian, primary peritoneal and/or fallopian tube cancer, and to compare these data with PK data from other clinical trials.
-To characterize the potential of a PK drug-drug interaction between pertuzumab and topotecan. |
