Collaboration between two Stanford labs has resulted in the discovery of a molecular cause for lymphedema the first possible drug treatment for it

Study finds first possible drug treatment for lymphedema

Collaboration between two Stanford labs has resulted in the discovery of a molecular cause for lymphedema and the first possible drug treatment for it.

Tracey Campbell has lived for seven years with lymphedema, a chronic condition that causes unsightly swelling in her left leg.

The disease, which stems from a damaged lymphatic system, can lead to infections, disfigurement, debilitating pain and disability. There is no cure. The only available treatment is to wear compression garments or use massage to suppress the swelling, which can occur throughout the body in some cases. Campbell — who had two quarts of excess water in her left leg by the time she was diagnosed — has for years worn restrictive garments 24 hours a day and has spent an hour each night massaging the lymph fluid out of her leg.

Lymphedema is uncomfortable, exhausting and dangerous if left uncontrolled. As many as 10 million Americans and hundreds of millions of people worldwide suffer from the condition, many from the after-effects of cancer therapy treatments.

“There’s this extra layer of emotional burden,” said Campbell, who added that she has to be constantly vigilant to protect against infection. “All you want to be is normal.”

Now there’s new hope for a possible pharmaceutical treatment for patients like Campbell. A study led by scientists at the Stanford University School of Medicine has uncovered for the first time the molecular mechanism responsible for triggering lymphedema, as well as a drug with the potential for inhibiting that process.

The study was published May 10 in Science Translational Medicine.

“We figured out that the biology behind what has been historically deemed the irreversible process of lymphedema is, in fact, reversible if you can turn the molecular machinery around,” said Stanley Rockson, MD, professor of cardiovascular medicine and the Allan and Tina Neill Professor of Lymphatic Research and Medicine at Stanford. Rockson shares senior authorship of the study with Mark Nicolls, MD, professor of pulmonary and critical care medicine. Stanford research scientists Wen “Amy” Tian, PhD, and Xinguo Jiang, MD, PhD, share lead authorship of the study and are also affiliated with the Veterans Affairs Palo Alto Health Care System.

‘Fundamental new discovery’

“This is a fundamental new discovery,” said Nicolls, who is also a researcher at the VA Palo Alto.

The researchers found that the buildup of lymph fluid is actually an inflammatory response within the tissue of the skin, not merely a “plumbing” problem within the lymphatic system, as previously thought.

Working in the lab, scientists discovered that a naturally occurring inflammatory substance known as leukotriene B4, or LTB4, is elevated in both animal models of lymphedema and in humans with the disease, and that at elevated levels it causes tissue inflammation and impaired lymphatic function.

Further research in mice showed that by using pharmacological agents to target LTB4, scientists were able to induce lymphatic repair and reversal of the disease processes.

“There is currently no drug treatment for lymphedema,” Tian said. Based on results of the study, the drug bestatin, which is not approved for use in the United States but which has been used for decades in Japan to treat cancer, was found to work well as an LTB4 inhibitor, with no side effects, she said.

Based on the research, bestatin (also known as ubenimex), is being tested in a clinical trial that started in May 2016 — known as ULTRA — as a treatment for secondary lymphedema, which occurs because of damage to the lymphatic system from surgery, radiation therapy, trauma or infection. Primary lymphedema, on the other hand, is hereditary. The results of the research pertain to both types.

Rockson is principal investigator for this multisite phase-2 clinical trial.

“The cool thing about this story — which you almost never see — is that a clinical trial testing the therapy has already started before the basic research was even published,” Nicolls said. “This is the first pharmaceutical company-sponsored trial for a medical treatment of lymphedema, a condition that affects millions.”

Nicolls and Tian are co-founders of Eiccose LLC. Eiccose is now part of Eiger BioPharmaceuticals, which gets the drug from Nippon Kayaku in Japan. Eiger is sponsoring the clinical trial. Nicolls and Rockson are both scientific advisers to the company.

Two labs, two diseases

The study, which got underway about four years ago, began somewhat uniquely as a collaboration between two labs that were studying two completely different diseases. At the time, the Nicolls lab, where Tian works, was studying pulmonary hypertension. The Rockson lab was conducting lymphedema research.

The two teams met through SPARK, a Stanford program designed to help scientists translate biomedical research into treatments for patients.

“I was in a privileged position of seeing two faculty conducting important research and recognizing the possible link in causality,” said Kevin Grimes, MD, associate professor of chemical and systems biology and co-founder of SPARK. “It occurred to me that both diseases affected vascular tissues and had strong inflammatory components.”

“He blind-dated us,” Nicolls said. “When Amy Tian and I looked at the data from Stan’s research, Amy said, ‘It looks like it could be the same molecular process.’”

“It was an arranged marriage between us and Stan which worked out great,” Tian said.

At the time, Rockson had begun to suspect that lymphedema was an inflammatory disease. This led to his team’s discovery that the anti-inflammatory drug ketoprofen successfully helped to relieve lymphedema symptoms, although it wasn’t a perfect drug; side effects were a concern, and it remained unclear how the drug worked at the molecular level.

Meanwhile, the Nicolls lab had discovered that LTB4 was part of the cycle of inflammation and injury that keeps pulmonary hypertension progressing. When researchers blocked LTB4 in rats with the disease, their symptoms lessened and blood vessels became less clogged, lowering blood pressure in the lungs.

“When we became aware of Mark’s work, we began to realize that we were both possibly dealing with the activation of steps downstream of the 5-LO [5-lipoxygenase] pathway,” Rockson said. “This became intriguing and formed the basis of our relationship.”

Joining forces

The two teams joined forces to figure out the mechanism that triggered lymphedema, hopefully revealing a target for drug treatment in humans. After determining that ketoprofen was primarily working on the 5-LO pathway, the researchers began blocking the various endpoint pathways after 5-LO activation in mouse models of lymphedema, Rockson said.

“It turned out that, in fact, we were both dealing with the same branch, which is LTB4,” Rockson said.

When all of the sudden one of your limbs begins to swell, you want to understand what the heck is going on.

“So now it became clear we really were dealing with a very similar biological process in two different diseases,” he said. “Because of Mark’s work in pulmonary hypertension, we knew that we had an ideal form of therapy that we could try in lymphedema as well.”

The Nicolls lab had used the drug bestatin, which blocks the enzyme that generates LTB4, to reverse pulmonary hypertension disease processes. When researchers tested bestatin in the mouse lymphedema model, it worked to reverse symptoms of that disease.

“I’m still in awe,” Rockson said. “There are few situations where you take a problem at the bedside, and go into the lab, and then take discoveries back to the bedside. It’s amazingly gratifying.”

Campbell, who is now participating in the double-blinded, placebo-controlled bestatin trial at Stanford, remains hopeful.

“When all of the sudden one of your limbs begins to swell, you want to understand what the heck is going on,” she said. “It’s a tough condition that few people seem to care about, even though millions and millions suffer with it. We’re hoping for something that gives some relief.”

Other Stanford authors are research associate Jeanna Kim; former medical students Adrian Begaye, MD, and Abdullah Feroze, MD; Roham Zamanian, MD, associate professor of medicine and director of the Adult Pulmonary Hypertension Service; Gundeep Dhillon, MD, associate professor of medicine and medical director of the Stanford Lung Transplant Program; and research assistants Eric Shuffle and Allen Tu. Shuffle and Tu are affiliated with both Stanford and the VA Palo Alto.

Researchers at Georgia Institute of Technology, Virginia Commonwealth University, the University of Michigan Health Systems and the University of Illinois at Chicago are also co-authors.

Eiger BioPharmaceuticals has licensed intellectual property developed by Tian, Rockson, Jiang, Kim and Nicolls involving the targeting of LTB4 for the treatment of lymphedema.

Fighting cancer with immunotherapy: Signaling molecule causes regression of blood vessels

Immunotherapy with T-cells offers great hope to people suffering from cancer. Some initial successes have already been made in treating blood cancer, but treating solid tumors remains a major challenge. The signaling molecule interferon gamma, which is produced by T-cells, plays a key role in the therapy. It cuts off the blood supply to tumors, as a new study reveals.

Immunotherapy with T-cells offers great hope to people suffering from cancer. Some initial successes have already been made in treating blood cancer, but treating solid tumors remains a major challenge. The signaling molecule interferon gamma, which is produced by T-cells, plays a key role in the therapy. It cuts off the blood supply to tumors, as a new study in the journal Nature reveals.

The immune system is the body’s most powerful weapon against diseases. So what if it were possible to use the immune system to fight cancer? For a long time now, researchers have been trying to do just that — for example, by employing a special kind of immune cell called T-cells. They are „special mobile forces“ that — after undergoing training — patrol the body, and can seek out and kill cancer cells. This strategy has been successful in initial clinical trials — but mostly just in the treatment of cancers that do not form tumors, such as blood cancer.

Good at fighting blood cancer, but not so effective against solid tumors

Large solid tumors, on the other hand, sometimes pose big problems for T-cells. Though adept at targeting cancer cells swimming in the bloodstream, they have difficulty attacking compact tumors. The tumor weakens the aggressors through the delivery of inhibiting signals.

The scientists working with Dr. Thomas Kammertöns, Prof. Thomas Blankenstein, Prof. Hans Schreiber and Christian Friese are searching for solutions with their research team at Charité — Universitätsmedizin Berlin, Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC), Berlin Institute of Health (BIH) and the Einstein Foundation.

In a study published in the journal Nature, they investigated how the signaling molecules of T-cells affect the immediate tumor environment, which includes the connective tissue as well as the blood vessels that supply the tumor.

T-cells produce not only tumor necrosis factor (TNF) but also the molecule interferon gamma (IFN-γ). Until now, however, there has been little understanding about how IFN-γ really works. „We knew that IFN-γ attacks cancer cells via the tumor microenvironment,“ says Kammertöns. „We now wanted to find out exactly which cells are targeted by the signaling molecules.“

Blood vessel regression is induced

The researchers generated genetically modified mice and used a clinically relevant cancer model. This included animals in which only blood vessel cells were susceptible to the signaling molecule.

In this mouse model IFN-γ pruned back the blood vessels in the tumors, thus shutting down the supply of oxygen and nutrients and killing the tumors. The researchers were able to observe this process microscopically in living mice in fine detail. They found that the blood vessel cells alone responded to the signaling molecule. When the researchers targeted other types of cells with IFN-γ, the tumors continued their growth.

These findings provided an explanation for the molecule’s powerful properties, which were already well known. „IFN-γ is one of the most important weapons in the T-cells‘ arsenal,“ says Thomas Kammertöns.

Thomas Blankenstein, lead investigator of the study, says: „The two together — IFN-γ and tumor necrosis factor — are a powerful team. TNF bursts tumor blood vessels, thus opening up the tissue, while IFN-γ cuts off the blood supply and keeps the tumor at bay over the long term.“

Optimizing T-cell therapy

The study offered the researchers clues on how to improve T-cell therapy for solid cancer tumors. Thomas Blankenstein explains: „We want to understand exactly how T-cells target tumors. Destroying a tumor’s infrastructure is probably more effective than killing individual cancer cells.“

„Our findings are significant beyond tumor therapy,“ says Thomas Kammertöns. „Interestingly, the mechanism used by IFN-γ to eliminate solid tumors resembles the physiological regression of blood vessels during development. It also disrupts wound healing.“

„IFN-γ might also affect the formation of new blood vessels after strokes or heart attacks. That’s why we want to find out more about the molecular processes behind all of this.“

Tests To Help With Breast Cancer Treatment Decisions

Herzlichen Dank an The Breast Cancer Authority!

When you’ve just received a diagnosis of breast cancer, you are faced with many different treatment options. Your mind is in a whirl with fear, confusion, and disbelief. While none of these feelings help decision making, there are some tests that can help: Oncotype DX and Mammaprint. 

These tests are genomic tests that analyze the activity of specific genes in the breast tumor. They can help you determine if your risk of breast cancer coming back is high or low, which can help you in making a decision about whether to have chemotherapy, radiation, or other therapies to reduce risk after surgery.

There are two main types of tests – Oncotype DX and Mammaprint.

Oncotype Dx has two tests for breast cancer – one for Ductal Carcinoma in situ (DCIS) – Oncotype DX DCIS and one for invasive breast cancer – Oncotype DX.  Mammaprint has one test for invasive breast cancer. Let’s look at these in greater detail.

What are genomic tests?

Genomic tests look at specific genes in your individual tumor and try to determine what is driving its growth. This is different from genetic tests which look at your inherited risk or predisposition for cancer. Genomic tests provide information that can help tailor your treatment plan to you as an individual. They are a type of personalized medicine. This is really important, because not all breast cancers are the same and, in fact, some breast cancers might have more in common with a prostate cancer than they do with another type of breast cancer. One size treatment definitely does not fit all.

Oncotype DX DCIS

This test is only for people diagnosed with DCIS or, as it is often called, “stage zero” breast cancer. In addition to general information such as tumor size, margins, and grade, Oncotype DX DCIS helps determine the likelihood of DCIS recurring or invasive breast cancer occurring within the next 10 years.

It examines a sample of the tumor tissue that has already been removed during the lumpectomy for DCIS. By looking at the expression of 21 different genes in the tumor, it provides a DCIS score of between 0-100. The lower the score, the lower the risk of recurrence. Two scores are given, one to determine the risk of recurrence of DCIS and another for the risk of occurrence of an invasive breast cancer.

Knowing the DCIS score can help you decide whether to have radiation treatment  following the lumpectomy. If your risk of recurrence is low, then maybe you can spare yourself further treatment and the possible side effects that go with it.

To be eligible for Oncotype DX DCIS, you need to have recently been diagnosed with DCIS and had lumpectomy surgery. The decision should be made in discussion with your doctor/oncologist.

In the US, insurance might cover the cost of this test; the testing company will help you determine if this is the case and provide information to your insurers, as necessary. In the UK, these tests can be conducted under the NHS or privately.

Many oncologists are now familiar with these tests for invasive breast cancer; sadly, the Oncotype DX DCIS test does not appear to be known by all oncologists, so it’s good for you to be proactive and start the discussion. Here is a link to the validation work done on the test that you can forward to your oncologist, and further links are given at the bottom of this post:

Clinical validation of oncotype DX DCIS

I definitely think it is worth having a discussion with your oncologist, sharing the references as necessary, and if you don’t get anywhere with the oncologist, talk to your family doctor or surgeon.

Oncotype DX and Mammaprint

Both Oncotype DX and Mammaprint are genomic tests suitable for early stage invasive breast cancer. They both predict the benefit of chemotherapy or other types of treatment, as well as the likelihood of 10 year recurrence.

They are similar tests but have some differences, as outlined below:

Comparison of oncotype DX and mammaprint for invasive breast cancer

Looking at this table can help determine if you are eligible for either of these tests.

As with Oncotype DX DCIS, some insurance companies in the US will pay for these tests whereas some don’t include them in coverage. Both testing companies offer financial assistance or guidance, so it’s worth calling them to discuss if you are interested and want to check coverage. In the UK, these tests can be conducted under the NHS or privately.

These tests are important because some of the cancer treatments, like chemotherapy, can have many side effects and are hard to get through. If there is little to no benefit in these treatments for you as an individual, then these genomic tests give you the confidence to not have a treatment that has greater potential for risk than for benefit.

Obviously the decision of further treatment is based on more than just these results. It involves detailed discussion with your oncologist, but also personal consideration of what you want and how you feel. Remember, you can take your time over treatment decisions. You might feel rushed, but take adequate time until you feel comfortable that you are making the right personal decision. These tests can go a long way in giving you confidence in your decision, but it is still a personal choice that needs to be right for you as an individual based on your mind and spirit, as well as your body.

Lymphedema After Mastectomy Breathing Exercises & Restorative Yoga

It is not unusual for a woman to develop lymphedema after a mastectomy. Lymphedema is a sometimes-painful swelling in the soft tissues.  This can be due to the removal of lymph nodes, scar tissue, strictures, and other factors.

Manual lymph drainage massage is the usual recommended technique to treat this swelling.  It may be surprising to know that another therapy that benefits lymphedema is yoga, especially restorative yoga. When the lymphatic system is at its optimum, it is like a free flowing river, running without obstacles.  However, when the lymph nodes are removed or damaged, that same river meets obstacles and begins to slow down and this creates a pooling of fluids.  This build up in the tissues can cause swelling and inflammation and reduce oxygen in the lymphatic tissues. The white blood cells, or immune soldiers of the body, can be impaired in their function in this situation.  This may increase the risk of infection and create a possible permanent disability.  Edema is often found in the arms and legs, but can be found in other parts of the body.

Knowing how important it is to keep this fluid running like a free flowing river, we need to foster relaxation and gentle movements that encourage its increased flow.  This is especially important after breast surgery or removal of nodes, when it is paramount to undertake new activities to increase impaired lymphatic function.

The need to develop a deeper state of relaxation to counter the mental and physical stress of illness and its treatment is critically important to our health and well-being.

Practicing yoga, especially Restorative Yoga which targets the pectoral area, keeps the fluid moving through the body rather than slowing down and creating a back up.  This benefits the breasts by promoting drainage and healing and creating a sense of safety when expanding the chest.

Practicing Restorative Yoga daily will undo the harmful effects of too much sitting or inactivity.  Starting yoga practice with a knowledgeable Restorative Yoga teacher is as important as wearing a bandage or support garment.

An important thing to understand in your practice of Restorative Yoga is that you must to slow down enough to listen to what your body is telling you.  Any time you overwork your muscles or strain your healing tissues,  you run the risk of fluid build up.

Let this be the yoga practice of self-understanding.

Herantis Pharma’s clinical study with Lymfactin advances to high dose level

Herantis Pharma’s clinical study with Lymfactin advances to high dose level

Herantis Pharma Plc
Company release 6 March 2017 at 10:00 am

Herantis Pharma Plc’s („Herantis“) clinical study with the company’s innovative gene therapy investigational product Lymfactin® for the treatment of secondary lymphedema has advanced to highest planned dose level owing to good reported safety. A Data Monitoring Committee of independent experts recommended proceeding to high dose treatments after assessing safety data on the previously treated patients. Following the recommendation, the first high dose treatment has already been administered.

 „We are naturally very happy for the safety of Lymfactin® in the first treatments“, comments Pekka Simula, Herantis‘ CEO. „This is the first clinical study in the world to apply gene therapy for repairing damages of the lymphatic system. Safety of the patients is our #1 priority so we want to move ahead carefully. We are thrilled to announce this milestone by coincidence on March 6: World Lymphedema Day!“

„Collaboration with the participating university hospitals in this study has been excellent“, adds Katarina Jääskeläinen, Herantis‘ Project Manager for the clinical study. „Secondary lymphedema is a disfiguring, disabling disease that severely impacts the quality of life of patients. We hope our Lymfactin® will significantly improve the quality of life of patients in the future.“

The Phase 1 clinical study continues recruiting patients with breast cancer associated lymphedema at three university hospitals in Finland: In Helsinki, Tampere, and Turku. The study intends to recruit at most 18 patients by the end of 2017.

World Lymphedema Day

March 6 was officially recognized World Lymphedema Day since 2015 by e.g. the U.S. Senate. It is celebrated around the world largely thanks to the patient advocacy group Lymphatic Education & Research Network (LE&RN) to increase lymphedema awareness.

About breast-cancer associated lymphedema

Approximately 20% of breast cancer patients who undergo axillary lymph node dissection develop secondary lymphedema, a chronic, progressive, disabling and disfiguring disease that severely affects quality of life. Symptoms include a chronic swelling of an upper limb, thickening and hardening of skin, loss of mobility and flexibility, pain, and susceptibility to secondary infections. Secondary lymphedema is currently treated with compression garments, special massage, and exercises. While these therapies may relief the symptoms in some patients they do not cure lymphedema, which is caused by damage to the lymphatic system. There are currently no approved medicines for the treatment of this condition.

About Lymfactin®

Lymfactin® is a gene therapy expressing the growth factor VEGF-C specific to the development of lymphatic vessels. Based on preclinical studies Lymfactin® triggers the growth of new functional lymphatic vasculature in the damaged area and thus repairs the underlying cause of secondary lymphedema. Lymfactin®, patented by Herantis, is based on the internationally renowned scientific research of academy professor Kari Alitalo and his research group, a national centre of excellence at the University of Helsinki. Herantis also holds patents for a combination therapy, which may expand the use of Lymfactin® in other lymphedemas. See our introductory video on Lymfactin®: http://herantis.com/media/videos/

About Herantis Pharma Plc

Herantis Pharma Plc is an innovative drug development company focused on regenerative medicine and unmet clinical needs. Our first-in-class assets are based on globally leading scientific research in their fields: CDNF for disease modification in neurodegenerative diseases, primarily Parkinson’s and ALS; and Lymfactin® for breast cancer associated lymphedema, with potential also in primary lymphedema.
