Immunotherapy Drug Combo Shrinks Tumor Size In 58% Skin Cancer Patients: New Cancer Treatment? Since the beginning of the “war on cancer” in the 1970s, we have made consistent progress against cancer aided by paradigm-shifting technological advances.
Drew Pardoll, MD, PhD, addresses participants in the Scientist-Survivor Program at the AACR Annual Meeting 2014. We asked experts on three hot topics—immunotherapy, cancer genomics, and cancer prevention—to share their thoughts on what will be big this year. The PD-1 checkpoint inhibitor, pembrolizumab, was approved by the FDA for the treatment of advanced melanoma in September 2014, which was followed by the approval of a similar drug, nivolumab, in December last year. The next big thing to expect in immunotherapy this year is a lot of clinical trial activity and results with therapies using genetically modified T-cells, so-called chimeric antigen receptor T cell (CAR-T cell) therapies, says Pardoll. Given that the overall response rates with immunotherapy based on immune checkpoint inhibitors is around 20 percent, Pardoll says, “we still have a long way to go.” However, he also reminds us that the overall impact of immunotherapy as measured in years of cancer remission is about 30 times greater than that of all of oncogene mutation-targeted therapies combined. The key to improving outcomes with immunotherapy lies in identifying the right patients for the right treatment. New methods of cancer screening, development of risk models that will identify high-risk individuals to improve risk-benefit ratio, and molecular imaging for early detection are other tremendously active areas of work, according to Lippman. Let’s look forward to an exciting and productive 2015 that brings more cancer drugs to patients, more tools to prevent and detect cancer early, and more information to the cancer research community that works tirelessly to change the way we deal with this dreadful disease.

Researchers used Timelapse Imaging Microscopy In Nanowell Grids (TIMING) to demonstrate that CD4+ CD19-chimeric antigen receptor (CAR+) T cells participate in multi-killing of tumor cells with slower kinetics of killing than CD8+CAR+T cells but high motility subgroups of both T-cell subsets have similar kinetics.
Researchers have created a new method for screening cells used in immunotherapy cancer treatments, allowing high-performing immune system cells to be studied in isolation and potentially expanding the number of patients for whom the breakthrough treatment proves successful.
Engineers from the University of Houston, working with physicians from the University of Texas M.D. He and Navin Varadarajan, assistant professor of chemical and biomolecular engineering at UH, collaborated with M.D. Clinical studies have reported life-saving results from cancer immunotherapy, a biological therapy which uses the immune system - or specific cells of the immune system - to fight cancer. TIMING could change that by allowing researchers to study many more interactions between immune cells and cancer cells, thanks to its ability to automatically analyze thousands of cell interactions at a time.
Most conventional methods assess a limited number of samples from a test - between 10 and 100, compared with the 10,000 or even 100,000 samples that can be assessed with the new method, according to the paper.
TIMING works like this: A nanowell grid - an expandable structure - allows discrete samples of immune cells and cancer cells to be confined and studied over time, via time-lapse video recording. Varadarajan said the system allows "high-performing outliers" to be identified for further research. Using the TIMING system, the researchers have deepened the scientific understanding of immunotherapy, including how different types of T cells function against cancer cells. CD8 T cells are known for their tumor-fighting properties, but Varadarajan said the finding, published in Cancer Immunology Research, suggests that CD4 cells also would be effective. Researchers at National Jewish Health have discovered how a lipid secreted by cancer tumors prevents the immune system from mounting an immune response against it. An abnormal immune response or "feedback loop" could very well be the underlying cause of metastases in oral cancers, according to Dr. Cancer is a disease of our genes - yet our understanding of how our genetic makeup affects our risk of cancer is still rudimentary. Here's one more reason to consider cutting back on the soda: drinking too many sugary drinks on a daily basis has been linked to gallbladder cancer. Scientists at Lancaster University have shed light on the metabolic switch observed in abnormal cells like cancer. Lung cancer is the most common cause of cancer deaths, accounting for about a third of all tumor-related deaths.
Rikki Rockett, drummer for the band POISON, got the best news of his life last week: his cancer is gone. Rockett says he joined the clinical trial not only out of concern about himself, but also about being around for his three-year-old daughter, Lucy, and his seven-year-old son, Jude. Immunotherapy is a relatively new form of treatment that boosts the body's immune system, better enabling it to attack cancer cells.
Rockett broke the good news last week via his Instagram account, where he posted a photo of himself with Cohen. Already feeling better for the past few weeks, Rockett is slowly getting back into Brazilian jiu-jitsu, riding his motorcycle and taking care of his kids. Rockett also wants to get the word out about immunotherapy — to those who have already exhausted other treatments like he did, but also to people newly diagnosed with cancer who might be able to avoid chemo and radiation. One of Rockett's immunotherapy drugs is pembrolizumab (Keytruda), an antibody that inhibits the abnormal interaction between the molecule PD-1 on immune cells and the molecule PD-L1 on cancer cells, effectively releasing the "brake" and allowing the immune cells to recognize and attack tumors. Moores Cancer Center is one of only 45 National Cancer Institute-designated comprehensive cancer centers in the country. For adults newly diagnosed with cancer, treatment at an NCI-designated comprehensive cancer center means superior survival and recovery rates due to the fullness of care, diverse medical, surgical, and radiation oncology sub-specialties, access to breakthrough clinical trials, advanced supportive care and utilization of exacting quality metrics. Patients have access to therapies, surgeries and clinical trials not offered in community settings. In late 2016, UC San Diego Health will open Jacobs Medical Center, a 245-bed, 10-story facility where patients with cancer will have access to the Pauline and Stanley Foster Pavilion for Cancer Care, a space dedicated to specialized oncology, and to the A. Ovarian cancer is often diagnosed when it is at an advanced stage, so chemotherapy is a key part of treatment. The researchers believe adding immunotherapy to chemotherapy could reverse the resistance to chemotherapy that invariably develops in patients with ovarian cancer and is a major reason for their low rate of survival.

In the journal Cell, researchers from the University of Michigan in Ann Arbor describe how they reversed chemotherapy resistance in mouse models of ovarian cancer by boosting the animals’ immune T cells. The team suggests the finding will prompt a re-think about chemotherapy resistance in ovarian cancer and could lead to new treatments using immunotherapy.
Ovarian cancer is one of the five main types of cancer that affect a woman’s reproductive organs.
Ovarian cancer is typically treated with a platinum-based chemotherapy called cisplatin, which causes platinum to build up inside the nucleus of cancer cells.
The researchers found that fibroblasts help ovarian cancer cells become resistant to cisplatin, and immune T cells work against this effect. However, when they added immune T cells to the fibroblasts, the tumor cells began to die off, showing that the immune system can affect chemotherapy resistance. Linking the findings back to patient outcomes, the team found that the presence of stromal fibroblasts is linked to lower patient survival, while the presence of immune T cells is linked to higher patient survival. They can see how it may be possible to use immune T cells to alter the behavior of the fibroblasts after chemoresistance develops.

As healthcare professionals, we are aware of the seemingly countless forms cancer can take in our patients and clients. The NSCLC therapy pipeline has several therapies that work differently from the more common chemotherapy drugs.  These treatments work by blocking specific changes in the cancer, which in turn, interrupts the growth and spread of the disease.
Another new exciting treatment, Eli Lilly’s CYRAMZA® (ramucirumab) received approval on December 12, 2014 for use in combination with docetaxel for the treatment of patients with NSCLC. CYRAMZA® is a vascular endothelial growth factor (VEGF) Receptor 2 antagonist.  Some tumors create proteins called VEGF. Clovis Oncology is currently studying rociletinib (CO-1686), a novel, oral, targeted   inhibitor of the cancer-causing mutant forms of epidermal growth factor receptor (EGFR) for the treatment of NSCLC.  The FDA has already granted Breakthrough Therapy designation for rociletinib as treatment for mutant forms of NSCLC in patients with the T790M mutation.
Clovis expects the data from their “TIGER” program – an accelerated clinical development program for rociletinib in patients with mutant EGFR NSCLC – to be the basis for a New Drug Application (NDA) filing sometime in mid-2015. These  new drugs currently under consideration differ from traditional chemotherapy because they target specific factors that encourage growth and work to block, or inhibit, those factors. While the new therapies in the pipeline is exciting, it is important to remember that many of these therapies currently target specific genetic mutations, making them options for certain NSCLC patients, but not all.
What breakthroughs can we expect in 2015 that would impact cancer prevention and make modern medicine work better and for more patients? I think there’s no reason to imagine that that’s not going to continue in 2015,” says Drew Pardoll, MD, PhD, professor of oncology, medicine, and pathology and co-director of the Cancer Immunology and Hematopoiesis Program at Johns Hopkins University. Pardoll, who is also a senior editor of the AACR journal Cancer Immunology Research, foresees the approval of immune checkpoint inhibitors for lung, bladder, kidney, and head and neck cancers, as well as Hodgkin lymphoma, in 2015. With combination therapies, we will have the opportunity to capture a larger number of patients into more durable response rates,” says Pardoll. Hahn, MD, PhD,  director of the Center for Cancer Genome Discovery at Dana-Farber Cancer Institute and associate professor in the department of medicine at Harvard Medical School. Hahn, MD, PhD, speaks at the 2013 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston. So far, we have learned that cancers are heterogeneous, and early work suggests that this heterogeneity is greater than initially imagined.
Studying cancer genomes in patients will allow us to find ways to identify at-risk patients, and make more accurate and earlier diagnoses,” adds Hahn, emphasizing the utility of genomics in advancing cancer prevention and early detection. He says this process has started but we are at the beginning, and likely to make significant progress this year. He points us toward the impact of hepatitis B vaccines on liver cancer rates, and more recently, HPV vaccines on anogenital cancers and on oropharyngeal neoplasia.
The proposal by the Centers for Medicare and Medicaid Services in November last year to add annual low-dose CT screening as a preventive test for heavy smokers is an important step in early detection, Lippman notes.
Focused efforts on studying the biology of premalignancy using large-scale sequencing efforts similar to the TCGA study will be in the forefront, and continued advancements in human genomics will play a critical role, he says.

But they don't work for everyone, not even everyone with one of the cancers for which the treatments have proven most successful.
Conventional analysis is done manually, the researchers said, making it impossible to study every combination. Several types of immune cells were used, including T cells, CAR cells - T cells modified with chimeric antigen receptors, which allow them to hone in on and kill cancer cells -and what are known as NK or "natural killer" cells, which can detect tumors without modification. As a result, they demonstrated for the first time at a single-cell level that CD4 T cells directly participate in the killing of multiple tumor cells. Several months ago, he came to Moores Cancer Center at UC San Diego Health, where he underwent experimental cancer immunotherapy, which has now eradicated the tumor.
Under the care of Ezra Cohen, MD, professor of medicine and associate director for Translational Science at Moores Cancer Center, Rockett participated in a clinical trial that is testing a combination of two immunotherapy drugs that remove defenses cancers use against the immune system.
Pembrolizumab is FDA-approved for some cancers, such as melanoma, but not Rocket's oral cancer. It is also the first and only San Diego-based member of the National Comprehensive Cancer Network, an alliance of the world's leading cancer centers, and is certified by the Quality Oncology Practice Initiative (QOPL), the leading quality program of the American Society of Clinical Oncology.

However, the cancer eventually develops resistance to chemotherapy – a major reason for its low survival rate. Rebecca Liu, associate professor of obstetrics and gynecology, and colleagues used tissue samples from patients with ovarian cancer and also mouse models of the disease to study the types of cell in the microenvironment of tumors.
Fibroblasts are cells that generate the connective tissue (the stroma) that supports cells. Liu and colleagues show that fibroblasts prevent platinum from building up in the ovarian tumor cells, resulting in resistance to cisplatin and survival of the cancer cells. Thus, it should be possible to return to the same chemotherapy drug that the patient had become resistant to, after immunotherapy has restored its effectiveness.

This awareness has helped us to better prepare patients and their families for the treatment process, as well as offer them more support resources than ever before. Food and Drug Administration (FDA) has accepted for filing the New Drug Application (NDA) for AstraZeneca’s IRESSA® (gefitinib) for the first line treatment of patients with advanced or metastatic epidermal growth factor receptor mutation positive (EGFRm) NSCLC, as identified through a companion diagnostic test.
These proteins attach to the VEGF receptors of blood vessel cells causing new blood vessels to form around the tumors, enabling growth. The way these drugs are designed to work is particularly exciting because the side effects from targeted therapy are far less invasive than those found in traditional chemotherapy –which is a much needed, and welcomed, respite from the rigors of managing a NSCLC diagnosis.
However, research into targeted therapies and immune therapies appears to be making bold steps in the right direction.
However effective targeted therapies may be, most patients develop resistance to these drugs, and with many drugs this often happens within a year of treatment.
We can expect to see encouraging results from studies using cancer vaccines, such as the attenuated Listeria monocytogenes vaccine engineered to express human mesothelin, in pancreatic cancer and mesothelioma, Pardoll adds. Another concept that we may hear more of in 2015, according to Pardoll, is adaptive resistance.
Cancer genomics has revolutionized the way we think about and treat cancer, and recent advancements and efforts are giving us the much-needed hope that we can use big data to better predict the disease. The large body of work that has been completed was focused on primary tumors—an essential starting point—but how cancers change over time is important to understand cancer better. Single cell-sequencing technologies will allow this to be explored in greater detail, he explains. We just ask that you credit Dana-Farber, link to the original article, and refrain from making edits that change the original context. They also demonstrated its potential in research evaluating how effective various types of T cells - a type of white blood cell key to fighting infection - are in killing cancer cells. This type of treatment is only available at a few specific medical centers around the country.
The other experimental immunotherapy drug he receives in the trial is epacadostat, which inhibits the IDO pathway.
These investigational therapies include advanced, highly personalized stem cell-based approaches and immunotherapies that leverage the inherent healing powers of the human body.
Now, new research suggests it may be possible to overcome chemotherapy resistance in ovarian cancer by adding immunotherapy to the chemotherapy. Immune T cells are the foot soldiers of the immune system and researchers have already shown that their high presence in tumors favors patient outcomes.
In fact, patient support has reached new heights as champions for breast cancer and prostate cancer, among others, have come forward to raise awareness about upcoming treatments. By inhibiting the tyrosine kinase enzyme in the EGFR, IRESSA® blocks the transmission of signals involved in the growth and spread of tumors.
Blocking the VEGF protein from linking to the blood vessels helps to inhibit tumor growth by slowing the formation of new vessel’s and the blood supply that feeds tumors.

Food and Drug Administration (FDA) of eight cancer drugs, including a few milestone “first-of-their-kind” drugs encompassing immunotherapies and targeted therapies, and a nine-valent vaccine that can prevent infections that cause cervical cancer. PD-L1 expression by tumor cells suggests that a patient has an extant antitumor immune response.
Understanding cancer genomes will facilitate matching patients to therapies that they are likely to respond to, and will allow us to identify and anticipate resistance mechanisms. Papers on that work were published earlier this year in Cancer Immunology Research and in OncoImmunology.

If a patient’s immune system does not have a strong enough antitumor response to induce PD-L1, a therapeutic maneuver to induce an antitumor immune response or amplify a weak one, such as a vaccine, will upregulate PD-L1. NSCLC treatment remains difficult and is largely an unmet medical need.   Because of this, there has been tremendous focus in the drug pipeline to bring to market some innovative therapies. Other experiences include managing clinical drug trials as well as designing company operational systems, processes, and standard protocols that focus on disease management and clinical informatics.
