Description of intervention(s) / exposure
This is an observational/non-interventional study.
The factors to be observed include the type of clinical characteristics of participants, such as age at diagnosis, performance status, and comorbidities; the type of tumour characteristics such as rate of hormone receptor positivity, sites of metastatic disease at diagnosis, rate of brain metastases at any time during the disease course, and time to relapse in participants with past history of early stage breast cancer; treatment patterns including the choice of HER2 agent for 1st, 2nd and 3rd line settings, choice of chemotherapy agent to be used in combination with HER2 therapy, and rate of treatment with trastuzumab beyond disease progression; and survival including overall survival and progression free survival in 1st, 2nd and 3rd line settings.

Not applicable
Comparator / control treatment
This registry will include all consecutive patients with HER2 positive metastatic breast cancer, who will differ in clinical characteristics, and for which treatment choice and efficacy will vary. Comparator groups will be derived from the data captured in the registry based on the specific observation or characteristic of interest (e.g. comparison of outcomes in participants aged <70 years vs. aged at least 70 years or participants who do vs. do not receive trastuzumab as 1st line treatment).

Statistical methods / analysis
As the aim of this study is to better understand the treatment and outcomes of HER2+ metastatic breast cancer for which there is currently very little data in a ‘real world’ setting, there is no formal statistical plan. It is anticipated that a sample size of 300 is sufficient to achieve the aim of this study, and to achieve preliminary insights into variation in practice and outcomes across sites

Summary
Brief summary
This study will collect data related to the management of women and men with HER2 positive metastatic breast cancer who are treated in routine clinical practice.

Who is it for?
You may be eligible to join this study if you are a patient of any age and any level of fitness with HER2+ metastatic breast cancer, of any hormone receptor status, either recurrent or de novo metastatic disease, who has either been diagnosed with metastatic disease within the last 3-6 months or who has progressed on 1st line therapy in the last 3-6 months.

Study details
For all patients enrolled in this study, data will be collected on the types of anti-HER2 therapies and chemotherapies used, how long treatment is given for, reasons for any changes in treatment, the impact of anti-HER2 therapies on heart function, and how often certain parts of the body, including the brain, are affected by HER2+ metastatic breast cancer. No personal/identifying data will be collected.

This study will help to improve our knowledge of the way that HER2+ metastatic breast cancer behaves, what types of treatment are effective, and the risks and benefits of these treatments within usual clinical practice conditions, with the aim of guiding future research of this disease and improving the outcomes for anyone affected by HER2+ metastatic breast cancer. All collected data will be compiled in a registry, which will be managed by BioGrid Australia. BioGrid Australia is a non-profit company that was set up to help with data collection and analyses for medical research.
