Despite the drop in smoking rates, lung cancer remains the second most common form of the disease in the United States. Scientists are hopeful that a recent discovery will aid the development of more effective immunotherapy for lung cancer.

A Roadblock in Lung Cancer Treatment

The immune system is the body’s first line of defense against foreign invaders. Immunotherapy is a form of cancer treatment that boosts the ability of the immune system to seek out and destroy cancer cells.

Current immunotherapy for lung cancer includes a drug that shuts down a protein on the surface of tumor cells. The protein, called PD-L1, latches on to T cells and prevents them from attacking.

Unfortunately, many lung cancer patients didn’t respond positively to this treatment. Scientists realized they needed to learn more about the “immune compartment of lung tumors,” which involves the relationship between the cancer cells and the tumor microenvironment.

Scientists Make a Breakthrough

A research team in Switzerland studied mice with a form of lung cancer similar to that in humans. They found that a type of immune cell known as Gr1+ neutrophils actually triggers a cycle in the microenvironment that promotes the growth of tumor cells.

Team leader Prof. Etienne Meylan explained that neutrophils are an essential part of the immune response, so removing them is not the answer. Future research will focus on how the neutrophils operate and how immunotherapy for lung cancer can work around them.

Some Types of Immunotherapy Can Cause Serious Side Effects

Some Types of Immunotherapy Can Cause Serious Side Effects

In 2017, the Food and Drug Administration (FDA) approved two new forms of cancer immunotherapy for use with certain types of blood cancer. While these treatments show great promise, scientists are also working to control their potential side effects.

Cancer Immunotherapy and CAR T-cells

Kymriah from Novartis is designed to treat a form of leukemia known as ALL, which is the most common cancer that affects children. The other new treatment, Kite Pharma’s Yescarta, is for non-Hodgkin’s lymphoma.

Both treatments incorporate CAR T-cell therapy, which uses the power of the body’s immune system. Specialized white blood cells known as T-cells are removed from a patient’s body and engineered to include a receptor designed to identify and attack cancer cells. The “new” cells are replicated and reintroduced to the patient’s system.

Dealing with Side Effects

Kymriah and Yescarta are one-time-only procedures that don’t have the common side effects normally associated with chemotherapy and radiation. But scientists have discovered that the treatments have some potential side effects of their own.

CAR T-cell therapy essentially supercharges the immune system, which can result in cytokine-release syndrome. The cells under attack release proteins called cytokines, setting off a massive inflammatory response including extreme fevers and seriously low blood pressure.

Fortunately, the side effects can be managed in a hospital or clinical setting. Researchers are seeking a way to make the therapies useable in a variety of settings.

State of the Art Research on Blood Cancers Is Under Way

2017 was a breakthrough year for cancer treatment. For the first time ever, the U.S. Food and Drug Administration (FDA) approved two gene therapies for blood cancers that have failed to respond to traditional forms of treatment.

Helping a Patient’s Own Body Fight Cancer

The new treatments are known as CAR-T cell immunotherapy. What’s exciting about these therapies is that they enhance the power of a patient’s own immune system to seek out and kill cancer cells.

T cells are immune system cells responsible for attacking foreign substances in the body. First, a doctor extracts T cells from a patient’s blood sample. The cells are then genetically modified to produce artificial proteins.

These proteins are called chimeric antigen receptors, or CAR, and they have the ability to recognize cancer cells in a patient. Once the modified T cells have been replicated, they’re reintroduced to the patient’s system to find and destroy cancer cells.

An “Explosion of Interest”

Kymriah, manufactured by Novartis, was approved for use with ALL, a form of leukemia that affects children and young adults. Gilead Sciences produces the other gene therapy, called Yescarta, which is used with non-Hodgkin lymphoma.

According to Dario Campano, an immunologist involved in the development of Kymriah, the approval of these therapies triggered an “explosion of interest.” Campano expects continued research to lead to greater advancements in the technology.

For decades, Issels® has been a leader in non-toxic immunotherapy for cancer treatments. The dendritic cell vaccine is one of the most potent weapons in our cancer-fighting arsenal, succeeding in many late-stage patients for whom other treatments had failed.

The Power of Dendritic Cells

Immunotherapy for cancer focuses on boosting the power of the body’s own immune system to fight tumors. Dendritic cells are part of the immune system, serving as advance sentries that recognize the presence of foreign antigens.

Once the dendritic cells process the antigens, they are presented to T cells, another part of the immune system. T cells are effectors that provide a response to stimulus such as bacteria, viruses and other invaders.

Individually, dendritic cells are extremely potent, but the problem is that they’re not usually present in large enough quantities. Dendritic cell vaccines are an effective method of increasing their numbers.

Issels® and the Dendritic Cell Vaccine

In a process called extracorporeal photophoresis, a patient’s blood passes through an ultraviolet light chamber, which provides an immune boosting effect. White blood cells are harvested and cultured into active dendritic cells, then re-injected into the body to trigger an immune response.

Traditional cancer treatments often have side effects because they attack healthy cells along with tumor cells. Dendritic cells can distinguish normal dying cells from cancer cells so the immune system refrains from attacking them.

Personalized Immunotherapy for Cancer at Issels®

Dendritic cell vaccines are only one of the innovative treatments we use for patients with all forms of cancer. Contact us to read and hear testimonials from our many patients who have successfully achieved long-term remission.

NIH Embraces Immunotherapy as a Top Cancer Treatment

The National Institutes of Health has named immunotherapy as a top form of cancer treatment. In the past, chemotherapy and radiation were typically the main types of cancer treatments that the NIH focused on. However, research findings and treatment advances have led to an increase in the demand for immunotherapy for cancer.

Fighting Cancer with the Immune System

Immunotherapy relies on the body’s immune system to seek out and destroy cancer cells before they have a chance to spread. This type of treatment focuses on strengthening natural immune defenses against cancer rather than targeting and destroying cancer with radiation or chemotherapy. This helps protect healthy cells from damage and lowers the risk of nausea and other potentially severe side effects.

Advances in Immunotherapy

Advances in immunotherapy for cancer have led to significant improvements in this type of treatment, which has resulted in a higher number of successes for those with certain types of cancer. Researchers are also doing studies to find out more about immunotherapy in order to provide more and more cancer patients with effective treatment.

Current research has been focusing on why this type of treatment works better for some patients, what other kinds of cancer it can be used for, and how to make it more effective when used in combination with other forms of cancer treatment. These findings should lead to even more successes for immunotherapy.

If you’re interested in learning more about how immunotherapy for cancer works, please contact Issels®. Our cancer treatments are nontoxic and can be effective for certain cancers that are difficult to treat.

Scientists are hopeful that a new gene therapy cancer treatment will lead to development of other drugs that utilize the power of a patient’s own immune system. In the meantime, policy makers face the challenges of safety, cost and access.

“Training” the Immune System to Fight Cancer

The therapy in question, called Kymriah, received approval from the Food and Drug Administration (FDA) in August 2017. Novartis developed Kymriah as a cancer treatment for children and young adults with a type of leukemia known as ALL.

Kymriah is a form of chimeric antigen receptor (CAR) T cell treatment. A patient’s T cells are genetically reengineered and infused back into the patient’s system to attack and kill cancer cells.

Weighing the Pros and Cons

During clinical trials conducted by Novartis, 63 patients received a one-time infusion of CAR T cells. After three months, 52 of the patients were in remission.

The downside is that 76 percent of the patients experienced a variety of side effects. In order to determine the overall risk vs. reward factor, the FDA has required Novartis to perform a post-marketing study of Kymriah’s safety and effectiveness.

An article published in the October issue of Health Affairs noted that high demand and high cost of CAR T cell therapies could lead to greater inequalities in health outcomes. The authors urged ethics and policy-making to catch up to the science of cancer treatment.
