Gina Wang, Director and Senior Principal Scientist working in HR-positive breast cancer
Nicole Richie, Global Head of Health Equity and Population Science

While breast cancer is a disease with many types <sup>1</sup>, it’s important to remember that every person with breast cancer is unique – with a unique set of personal circumstances, history, geography, and socioeconomic considerations that accompany the diagnosis. Only when we work to understand the whole picture, can we help improve and tailor breast cancer care. We hear from some of our brilliant women working to help improve care in the most common type of breast cancer, known as hormone receptor (HR)-positive breast cancer.

Gina: For me, it is always important to step back and reflect on how tremendously meaningful it is to work in breast cancer. As a scientist and researcher, I have witnessed incredible breakthroughs in care in the last few decades, and yet this year we saw breast cancer become the leading form of cancer worldwide.2 This is evident when you talk to people; most people have been touched by breast cancer in some way whether it be a family member, friend, or colleague. With one in seven people in Europe diagnosed at some point in their life, the burden of breast cancer on society is huge.3

Nicole: Absolutely, and it’s so important to highlight that it’s a global issue. We need to be focused on helping to resolve inequities in breast cancer care that we know exist around the world.4 My work focuses on improving inclusion and access to our clinical trials to ensure that certain patient populations aren’t left behind. This involves creating new foundations for reaching patients, supporting better patient representation, and helping to improve healthcare ecosystems. But how do we build clinical studies that are as diverse as the breast cancer patients we see?

Gina: Exactly, it starts with setting up studies that speak to and support different types of patients. This is a key focus for our teams within Roche who run studies in HR-positive breast cancer – the most common type of breast cancer.5 We have branched out from regions where studies have ‘traditionally’ been run (e.g., predominantly in Europe and the US) to new territories in East Africa, South America, the Philippines, and India, for example. This means we can reach out as widely as possible to areas where access to innovative medicines may be more limited

Nicole: We’re also building support systems in our studies that aim to be as diverse as the patients we enrol. This could involve providing upfront stipends to patients to cover travel costs, to ensuring that we have patient liaison representatives who belong to the same community as them. And let’s not forget, many breast cancer patients are also mothers as well – how do they continue to care for their children when they're participating in a clinical trial? So, we also offer childcare reimbursement in our aim to be as inclusive as possible.

And we know that in some countries and regions, as well as certain populations within countries, that disparities exist in breast cancer outcomes.4,6 We certainly know this is the case in hormone receptor-positive breast cancer.6

Gina: Yes, and there needs to be more awareness of this. At the heart of understanding these disparities is the need to study them. We know that biology matters, access to healthcare matters, and socioeconomic factors matter6,7 – but we need to tease out the impact of each and we can only do this by ensuring we have representation in our clinical studies.

Nicole: One of the things I was just reflecting on is the role women have as decision makers in their households. Did you know that women make 80% of healthcare decisions for their families?8 They're the CEOs of healthcare in their households! The decisions that women with breast cancer make have massive implications for their family, as well as them personally. This also applies to other diseases that disproportionately affect women, or disproportionately have poorer outcomes in certain populations of women.

 Gina: And when trying to improve outcomes for people with breast cancer, we have such an incredible legacy at Roche. We’re developing the medicines of tomorrow to improve care for every patient, and if we do this, we will also positively impact those around them. As mentioned, the majority of diagnoses in breast cancer are of the HR-positive type (this represents about 70% of cases).5 We know that these patients have many unmet needs,9 and my team is fully focussed on helping to overcome them. A major problem is poor adherence to standard of care treatment due to the impact of side effects. In fact, up to 50% of patients discontinue treatment10– this is an alarming figure that we need to resolve through the development of more effective and tolerable medicines.

Nicole: And what if you are a single mother or the sole breadwinner of the family, or in a situation where you simply cannot afford not to comply with your treatment? People with HR-positive breast cancer are having to make incredible sacrifices, so helping develop a potentially more tolerable and effective treatment could have such an impact. Its impact that goes far beyond the medicine itself.

Gina: And this comes back to our patient centric focus, our culture that fosters innovation and our focus on research to find better, more tailored therapies for all patients. Let’s continue to shine a light on some of the disparities and unmet needs that exist for patients with breast cancer. It’s a tremendous privilege to be working with you all on this – we know that this is not easy but through incremental steps, passion and persistence we will see in breakthroughs that breast cancer patients are waiting for.
