Understanding Immunotherapy Part 1: What is Immunotherapy?

By Amrita Bhatt, MRA Intern

If you follow science, you have probably heard about immunotherapy. In just the last year or two, immunotherapy has burst into the mainstream media, with coverage from the New York Times to Time Magazine bringing this emerging field to light beyond the scientific community. More recently, President Jimmy Carter helped put a face on immunotherapy when he announced its use in treating his metastatic melanoma.

While there is a broader understanding of immunotherapy now than there was a few years ago, there is a lot to discuss on this complex topic. We’ll be starting a blog series to help readers understand immunotherapy – and how it is being used to treat melanoma and other cancers.

Let’s start with a little background. Just 10 years ago, there were hardly any treatments available for patients diagnosed with melanoma, and a diagnosis of metastatic melanoma was an almost certain death sentence. Since MRA’s founding, the FDA has approved 11 therapies for melanoma. These have included targeted and immunotherapies – and combinations of the two. With nearly $68 million in funding to date, MRA continues to play an integral role in making revolutionary changes available for patients.

So, what is immunotherapy?

It’s a method of treatment that involves engaging the patient’s own immune system to fight cancerous cells. Four of the eleven FDA approved therapies since 2011 have been checkpoint therapies, including one combination therapy, and MRA’s funding has been vital to keeping the momentum going.

How does immunotherapy work?

Our immune system protects us by warding off foreign invaders such as bacteria and viruses. The immune system can also sometimes recognize cancer cells. However, since cancer cells arise from our normal cells, sometimes the cancer just isn’t different enough for the immune system to attack it.

In some cases, even when recognized as foreign, cancers use other strategies to evade the immune response. Immunotherapy works to boost your body’s immune response in order to attack cancer cells and prevent them from evading our defenses.

This video provides a visual explanation for how immunotherapy works.

Figuring out how to engage the immune system to fight cancer has been a goal for many years. MRA has funded a great deal of research in this area, including research on two proteins that allow cancer cells to escape attack from the immune system – PD-1 and CTLA-4.

In this continuing blog series, we’ll explain what these proteins are and how MRA funded researchers are strengthening our understanding of their role in cancer progression and treatment. Immunotherapy is broadening the scope of patient therapies and we must continue to fund vital research that keeps the momentum going.

Wendy Selig, MRA President & CEOWe are delighted to be launching the Melanoma Research Alliance (MRA) blog – welcome!  We felt the name Melanoma Focus had important significance because MRA is singularly focused on defeating melanoma and moving toward a day when no one suffers or dies from this deadly cancer.  And we know how important it is that we elevate the focus and attention paid to this insidious disease among all stakeholders – patients, their families, all who are at risk and our growing cadre of allies across the non-profit, for-profit and government sectors.

As part of MRA’s focus on melanoma, we stay connected with news and developments related to academic melanoma research, healthcare policy and commercial drug development.  We hope this blog can serve as a resource for those looking for melanoma news and the latest developments in the field.

MRA is not alone in the fight against melanoma—we are joined by dozens of committed corporate and non-profit allies helping us raise awareness and research funds.  We will use this blog to showcase the unique platforms and empowering information our allies offer, as well as to highlight the innovative collaborations that we are pursuing to help defeat melanoma together.

Every eight minutes, someone in the U.S. is diagnosed with melanoma and every hour someone succumbs to this terrible disease.  Each of those individuals has a story to tell.  Our partners, sponsored investigators, and supporters all have unique stories about how melanoma touched their lives and why they chose to get involved with MRA.   Melanoma Focus will serve as a place to share these diverse stories and experiences with a wider audience.

We hope that you will enjoy the blog and join the melanoma discussion, either by commenting here or by engaging with MRA on social media.  Together, we can get to a day where no one suffers or dies from melanoma.
