    General information about the trial
    Main objective of the trial
    The primary objective of this 2-cohort, open-label, multicenter, phase 2 study was overall response rates (ORR), assessed by investigator, of pertuzumab given in combination with trastuzumab (Herceptin) and vinorelbine in first line participants with metastatic or locally advanced human epidermal growth factor receptor (HER) 2-positive breast cancer. Participants received pertuzumab and trastuzumab administered sequentially as separate intravenous (IV) infusions (followed by vinorelbine) and conventional sequential administration of pertuzumab and trastuzumab in separate infusion bags, followed by vinorelbine.
    Protection of trial subjects
    The study was conducted in accordance with the principles of the “Declaration of Helsinki” and Good Clinical Practice (GCP). Approval from the Independent Ethics Committee/Institutional Review Board (IEC/IRB) was obtained before study start and was documented in a letter to the Investigator specifying the date on which the committee met and granted the approval. The Sponsor also obtained approval from the relevant Competent Authority prior to starting the study.

    Pre-assignment
    Screening details
    Due to non-randomized nature of the study (single infusion cohort started enrollment only after separate infusion cohort recruitment was completed) and different baseline characteristics of participants, the comparison between the 2 cohorts was not performed. Hence, the efficacy and safety results for the 2 cohorts should be considered separately.

    Percentage of Participants With Best Overall Response (BOR) as Assessed by Investigator According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) [1]
    End point description
    Tumor response was assessed by investigator according to RECIST v1.1. BOR was defined as percentage of participants with a confirmed complete response (CR) or partial response (PR). All measurable lesions up to a maximum of 2 lesions per organ and 5 lesions in total or pathological nodes (with short axis [SA] of at least (>/=) 15 millimeter [mm]) were identified as target lesions (TLs) and measured and recorded at baseline. A sum of diameters (longest for non-nodal lesions, SA for nodal lesions) for all TLs was calculated and reported as baseline sum of diameters (SD). All other lesions (or sites of disease) were identified as non-TLs. CR: disappearance of all TLs and SA reduction to less than (<) 10 mm for nodal TLs/ non-TLs. PR: >/=30 percent (%) decrease in SD of TLs, taking as reference baseline SD. Confirmation of response at 2 consecutive tumor assessments >/=4 weeks apart was required. The 95% confidence interval (CI) was computed using Clopper-Pearson approach. ITT population.

    Time to Progression (TTP) as Assessed by Investigator According to RECIST v 1.1
    End point description
    TTP was defined as the time from first intake of any study medication until the first radio-graphically documented PD as assessed by investigator according to RECIST v1.1. Participants who did not have a radio-graphically documented PD and had died due to reason other than PD were censored on the last available tumor assessment prior to the death date. Participants with no baseline or no tumor assessment after the baseline visit were censored on the date of first study treatment. PD: >/=20% relative increase and >/=5 mm of absolute increase in the SD of TLs, taking as reference the smallest SD recorded since treatment started, or appearance of 1 or more new lesions. Participants who had radio-graphically documented PD as assessed by investigator according to RECIST v1.1 were considered as having an event. The median TTP was estimated using Kaplan-Meier method. The 95% CI was computed using log-log transformation. ITT population.

    Overall Survival (OS)
    End point description
    OS was defined as the time from first intake of any study medication to the date of death, regardless of the cause of death. Participants who were known to be alive at the time of the analysis were censored at the date of the last follow-up assessment. Participants without follow-up assessment were censored at the day of last study treatment, and participants with no post-baseline information were censored at the date of first study treatment plus 1 day. Participants who died due to any cause were considered as having an event. The median OS was estimated using Kaplan-Meier method. The 95% CI was computed using log-log transformation. ITT population. The data ‘99999 (99999 to 99999)’ in the results signifies that median and corresponding CI could not be calculated due to low number of participants who had an event.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    05 Mar 2012
    - As MO27782 was an open-label study, words referring to randomization were removed and/or replaced - The study treatment administration scheme was corrected - The algorithm for continuation and discontinuation of pertuzumab and trastuzumab based on left ventricular ejection fraction (LVEF) assessments were revised in order to be consistent with the baseline LVEF criteria of >/= 55% - Clarification of several exclusion criteria - Clarification of the role of the IDMC - Changes to the prior and concomitant medications and therapies - Change to the time of the final analysis of primary endpoint
    23 Jan 2013
    - Clarification of the timing of the IDMC review - Inclusion of participants who had received hormonal therapy. To reflect the current use of hormonal therapies and everolimus in the participant population, the protocol was amended to allow inclusion of participants who, prior to study entry had received up to two lines of hormonal therapies for metastatic or locally recurrent disease, one of which could have been in combination with everolimus - Inclusion of participants with central nervous system (CNS) metastases, if the CNS metastases were medically well controlled prior to screening (as assessed by the investigator) after receiving local therapy (irradiation, surgery, etc) but without anti-Human Epidermal Growth Factor Receptor (HER) 2 therapy - Clarification of several exclusion criteria (including the exclusion of participants with cardiac disorders at risk of an serious adverse event) - Endpoint assessment and study end. Modification to timing of final assessment of ORR to enable timely results, rather than an open-ended final assessment time. Clarification of OS analysis timing and end of study - Infusion times and scheduling. New instructions introduced to enable appropriate monitoring of safety during initial pertuzumab/trastuzumab infusions - Abnormal liver values. New section introduced providing guidance on abnormal liver values, as required by updated Roche protocol template - Clarification of coagulation testing and HER2 status assessments
    20 Jan 2014
    - Removal of the use of the Independent Review Committee to assess the primary endpoint. Amended to “the primary endpoint to include ORR as assessed by the Investigator” - Analysis sections updated to ensure an accurate description of data evaluation. Efficacy endpoints were to be presented by each cohort with an exploratory comparison between cohorts only - Pregnancy follow-up. Increased pregnancy follow-up, restrictions on breastfeeding and use of adequate contraception to 7 months following last dose of study medication, in line with changes to recommendations given in trastuzumab labeling - Scope of interim review. Defined to reflect that efficacy data were to have been provided if requested by the IDMC, as outlined in the IDMC charter - Definition of secondary variables (time to response, duration of response, PFS, time to progression and overall survival) were amended to be measured as time from first intake of study medication rather than time from date of enrollment as this provided a more accurate measure of these endpoints. Documentation of PFS was broadened to include the option of pathological diagnosis of progression
