If one is good and two is better, is three the answer? Scientists are hoping that a new three-part molecule could be an answer regarding effective immuno oncology for breast cancer patients.

Stemming the Growth of Breast Cancer Cells

Approximately 20 to 30 percent of breast cancer cases involve over-expression of HER2, which is a growth factor that leads to aggressive multiplication of cancer cells. This acceleration often makes these types of cancer resistant to therapy, resulting in poor prognoses.

Dr. Hongyan Liu, a bioengineer at the Georgia Cancer Center, led a team that developed a chimera, or three-part molecule, to suppress the growth factors. The chimera targets HER2, HER3 and EGFR because one member of the HER “family” can compensate when another one is blocked.

Exploring the Abilities of the Three-Part Molecule

The new molecule is non-toxic, easy to manufacture and relatively cost-effective, making scientists optimistic about its value for immuno oncology. Dr. Liu and her team are currently conducting studies to determine if the chimera can treat cancer that is resistant to Herceptin, a drug that inhibits HER2.

Breast cancer is not the only form that grows due to over-expression of HER receptors. Dr. Liu is hopeful that the chimera will have future applications for lung, head and neck cancers as well.

Ovarian and uterine cancers are often detected too late for effective treatment. Immuno oncology got a major boost recently with the development of an advanced Pap test that can provide early diagnosis.

Improving Early Detection of Female Pelvic Cancers

Researchers from McGill University and Johns Hopkins University teamed up to work on PapSEEK. This safe and minimally invasive test uses Pap samples from the uterus, cervix and blood to identify common genetic mutations in cancer DNA.

While the standard Pap test collects samples from the cervix, McGill professor Lucy Hopkins suggested that the team collect samples from the uterus as well to increase chances of detecting other types of cancer. They used a method called the Tao brush technique to improve the sensitivity of the test.

Going Beyond Traditional Testing

PapSEEK was tested on samples from more than 1,300 women from different hospital sites in different countries. Just over 600 of the samples were from patients with endometrial or ovarian cancer, while the others were healthy controls.

The researchers were able to detect 81 percent of endometrial cancers and 33 percent of ovarian cancers, with higher rates when the Tao brush technique was implemented. In addition, there were no false-positive results.

According to Gilbert, the Pap smear has reduced the number of cervical cancer deaths, but endometrial and ovarian cancers were going undetected. Gilbert believes that PapSEEK will be a valuable breakthrough, just as the original Pap test was.

Bringing a new immuno oncology drug to market is an expensive and time-consuming proposition. A team of researchers is trying to expedite the process, using computer modeling to find a drug that treats metastasized breast cancer.

Can One Drug Fight Two Types of Cancer?

Triple negative breast cancer is the most difficult form to treat. Once the cancer metastasizes to the brain, survival time is generally shorter. Scientists at Houston Methodist analyzed thousands of current drugs in search of one that could prevent metastasis.

The team’s efforts paid off when they hit on edelfosine, a drug which is FDA-approved for investigational leukemia treatment. Edelfosine has also been the subject of clinical research for primary brain tumors.

In a study to test the discovery, mice were injected with triple negative breast cancer stem cells obtained from patients. The cancer cells metastasized to the brain, but treatment with edelfosine prevented the cells from further growth.

A “Game-Changer” in Immuno Oncology

Dr. Stephen T. Wong, one of the study’s authors, referred to the concept of repurposing drug compounds to prevent metastatic brain cancer as a “game-changer.” In past research, Wong and his co-workers have discovered other drugs that are being repurposed in clinical trials.

The study’s co-author, Dr. Hong Zhao, said they hope to move edelfosine to a phase II clinical study within the next few years. In addition, scientists want to investigate use of the compound on other forms of cancer.

Take Care with Antibiotics Now to Prevent Cancer Treatment Hampering Reactions

Doctors always take care when prescribing combinations of drugs due to possible negative interactions. It’s not surprising that mounting evidence indicates the complex balance of targeted cancer treatment can be upset by use of antibiotics.

Disrupting the Body’s Natural Defenses

According to results of a study conducted at the Georgia Cancer Center, this problem stems from the effect of antibiotics on gut microbiota, the network of bacteria, viruses and fungi that resides in the digestive tract. These “good” germs aid with digestion and protect our system from “bad” germs.

In the process of killing off microorganisms that cause infections, antibiotics also destroy large amounts of gut bacteria. As a result, patients on a course of antibiotics often experience nausea, vomiting, diarrhea and other gastrointestinal symptoms.

The Connection Between Gut Bacteria and Cancer Treatment

Dr. Gang Zhou, corresponding author of the study, explained that certain bacteria in the microbiota are necessary to activate the T-cells involved in cancer treatment known as adoptive T-cell therapy. A newer form of treatment called CAR T-cell therapy appears to be resistant to the antibiotic effect because it works on its own, with little reliance on the immune system.

Co-author Dr. Locke Bryan pointed out that antibiotics are often used in conjunction with chemotherapy. This traditional cancer treatment lowers white blood cell counts to the point where there’s no defense against bacteria, and an infection can be lethal to an already weakened immune system.

Tumors have a number of ways to avoid detection and attack by the body’s immune system, making them difficult to eliminate. In a victory for cancer immunotherapy, scientists have created a synthetic protein with the ability to reverse these defenses.

Overcoming Safeguards of Tumor Cells

Most diseased cells carry proteins called antigens that trigger a response from T cells in the immune system, resulting in neutralization of the threat. In contrast, tumor cells secrete immunosuppressive cytokines, and these soluble proteins disable the immune response from T cells.

Chimeric antigen receptor (CAR) T-cell therapy, which received FDA approval in 2017, has been successfully used to treat blood cancers such as leukemia. Unfortunately, these therapies have not had a similar effect on solid tumors.

Making Cancer Work Against Itself

Building on the principle of CARs and their power to counteract the defenses of cancer cells, a team of scientists at UCLA engineered CARs to respond to soluble proteins along with surface-bound antigens. In effect, cancer’s primary weapon ends up acting as an instrument of its own destruction.

Since these CARs are engineered, it opens up the possibility of using this method to create cancer immunotherapy treatments for other applications. The UCLA team has already engineered CARs that respond to various soluble proteins, including transforming growth factor (TGF) beta.

Super powers are usually the stuff of comic books and movies, but a biotech startup may be turning fiction into reality with the development of “superblood” as a revolutionary new cancer treatment.

“Supercharging” Red Blood Cells

Rubius Therapeutics is working on a program called Red-Cell Therapeutics (RCT), which involves red blood cells that are genetically engineered to fight cancer. Once introduced into a patient’s system, these proteins can replace missing enzymes and help the immune system attack and destroy cancer cells.

RCT has two major advantages that make it a promising breakthrough in cancer treatment:

– The nuclei have been removed from these cells so they can’t be recognized by the immune system, leaving them free from interference so they can do their job.

– Red blood cells travel throughout the entire body, so RCT is able to easily reach any affected organs or tissues.

Thanks to these two features, RCT has the potential to treat patients without the need for an individually developed solution.

What’s Next?

Initially, Rubius Therapeutics generated $120 million from investors. The company recently raised an additional $100 million for a total of nearly a quarter of a billion dollars in less than one year. According to Rubius president Torben Straight Nissen, this funding will help accelerate RCT development for quicker delivery to the end users.
