“What Can I Do to Prolong the Life of My Kidneys?” June 1, 2018 by Lauren Eva Read our expert panel’s answers to this community-generated question. Mindy Banks, MD Rocky Mountain Pediatric Kidney Center Denver, CO FSGS, or focal segmental glomerulosclerosis, is a diagnosis that is made based on kidney biopsy often after it is noted that a person has high amounts of protein in the urine, high cholesterol, and/or swelling. Hypertension and progressive kidney dysfunction can also be a part of the disease. FSGS is really a descriptive term where scarring is found in segmental portions of the some of the filtering units of the kidney, also known as “glomeruli”. Because it is a descriptive term, there are actually many different underlying causes, including immunologic (essentially “autoimmune” in nature, often responsive to medications that suppress the immune system), genetic, viral (such as HIV), obesity, severe prematurity with intrauterine growth restriction, and even related to scarring from other primary disorders, such as lupus. Because there is such a wide range of causes of FSGS, there are also varying approaches to treatment. Often, medications such as prednisone or other steroids are first-line therapies. It is important to take these medications as prescribed and not miss doses because these medications can affect the normal functioning of the adrenal glands. Therefore, a person can become quite sick if doses are missed without their doctor knowing. Not taking medications as prescribed may also decrease their efficacy. Calcineurin inhibitors (tacrolimus and cyclosporine), are also commonly prescribed. These medications are time-sensitive and must be taken every 12 hours apart to achieve appropriate levels and not risk toxicity. These medications also have many significant interactions with food you may eat or other medications you may take. Other immunosuppressive therapies have been tried, including mycophenolate (CellCept), rituximab, plasmapheresis, LDL pheresis, and abatacept, each with its own side-effect profile. Being your own advocate and discussing options in detail with your provider is important to make sure you understand the medications you are taking, how to take them, and what the risks are. Without this knowledge, you may not be getting the medications’ full benefit and be putting yourself at unnecessary risk. Non-immunosuppressive interventions are also important. ACE inhibitors (such as lisinopril or enalapril) or ARBs (such as losartan) are blood pressure medications that are also useful to help reduce the protein in the urine by preferentially decreasing pressure inside the filtering units of the kidneys. Statins, which are high cholesterol medications, can also be very helpful. Water pills such as Lasix/furosemide may also be necessary to control swelling. Good diet and exercise are also important parts of the equation. Restricting sodium in the diet helps reduce the amount of diuretic that may be needed and thus, limit side effects. A low-sodium diet can also help with hypertension. Protein is not usually restricted if someone is spilling significant amounts of protein in the urine. Controlling obesity also limits the stress on the kidneys and can slow progression of the FSGS. Certainly, avoiding smoking is critical to the lifespan of any kidney. Having an FSGS diagnosis can profoundly impact a person’s life. However, it is important to know that you have the power to make a difference in your health. It is important to work with your providers to come up with a healthcare plan that works individually for you. Find a team that you trust and communicate well with. Be involved and be your own advocate. Lastly, find a support group to help you through this. Treating your mental health is just as important as treating your physical health. You are not alone and you can do this! Dr. Mindy Banks is board-certified in pediatrics, internal medicine, adult nephrology and pediatric nephrology. Her combined internal medicine/pediatrics training was at Nationwide Children’s Hospital in Columbus, Ohio. She continued her medical training in the Midwest with fellowship at Northwestern University Hospital and Lurie Children’s Hospital in Chicago. Her medical practice focuses on children and young adults with the whole spectrum of kidney diseases ranging from frequent urinary tract infections to hypertension, nephrotic syndrome, dialysis and post kidney transplant care. She lives in Denver, Colorado with her husband and 3 boys. Besides nephrology, her life is spent either with sticky fingers from crafting or baking or sitting sidelines at a soccer game. Diane K. Jorkasky, MD, FACP Complexa, Inc. Berwyn, PA Having been in clinical research for 30 years as well as having been in practice in nephrology, I have seen as new medicines have come to make a huge difference in patients’ lives. Unfortunately, few of those medicines have benefited kidney disease. When I advise a patient on how best to manage their disease, I think about how I advise my own parents. The first is to make sure you read and know as much about the disease as you can. You have to do your homework. But you have to be careful as there is a lot of misinformation out there, especially on the internet. I would turn to sources such as NephCure Kidney International or other patient advocacy organizations as they provide extremely important and correct information to patients. The patient with the disease is always first in their minds. Do not be afraid to ask your doctor questions! A good doctor always takes the time to speak to their patients, no matter how busy they are. Write down your questions and take the list with you when you see your doctor. If the doctor ignores your questions or dismisses them, I would look for another doctor. The second thing is to ensure that you follow the instructions that your doctor recommends. All kidney diseases, regardless of cause, will get worse if your blood pressure is abnormally high, for example. Taking your blood pressure as prescribed and watching your diet is extremely important for patients with kidney disease and Nephrotic Syndrome. Finally, it is important to ask your doctor about clinical trials that may be ongoing or are about to start for new medicines that could benefit your kidney disease. Many of the current medicines used in kidney disease have severe side effects, like prednisone. Do not assume that your doctor knows what new medicines may be available for use in a clinical trial. NephCure and some, but not all, disease advocacy websites may list the drugs, the studies and the nephrology practices in the country where trials are being conducted. The only way that old, poorly effective and very risky drugs can be replaced with good ones that truly make a difference in the disease is by studying them in clinical trials. There are now more drugs than ever being considered for the treatment of FSGS and other kidney diseases. I would encourage patients to think about exploring these opportunities. Your physician can guide you on this journey as well. Be inquisitive, as it can make a difference in your life.

Jenna Henderson, ND Holistic Kidney New Paltz, NY FSGS and Minimal Change patients from all over the world consult with our naturopathic clinic, Holistic Kidney. Many of them are looking for alternatives to medications or as adjunct therapy for when medications help somewhat but they are still not able to reach full remission. Naturopathic doctors are the only healthcare professionals with broad training in both botanical medicine and pharmacology. I can tell if a particular herb would work well with a patient’s current prescription medications. I don’t encourage patients to abruptly stop any medication, but over time, we may be able to reduce the need for some medications. We recommend plant-based supplements and dietary changes to reduce kidney inflammation and proteinuria. We also address long term cardiovascular health and bone density issues for patients. The connection between Nephrotic Syndrome and low-thyroid hormones is often not talked about, even though many kidney patients report feeling chronically cold. This is something we address. We also consider chronic insomnia, which is very common with Nephrotic Syndrome. By looking at Nephrotic Syndrome from different perspectives, we are able to use natural medicine to reduce kidney stress and improve kidney function. Dr. Jenna Henderson’s practice, Holistic Kidney, is dedicated to the unique needs of renal patients with an international clientele and patients on 6 continents. A kidney patient herself for over 25 years, she has experienced all stages of kidney disease firsthand. She is a graduate of the University of Bridgeport. Dr. Henderson has had several articles on kidney health published in Townsend Letter, Natural Medicine Journal, and NDNR. She has lectured extensively across the U.S. to naturopathic doctors, kidney patients and kidney professionals, and co-hosted the radio show Improve Your Kidney Health. Dr. Henderson seeks to bridge the gap between mainstream nephrology and natural medicine. In her practice, she helps patients sort through often conflicting information to understand what is appropriate for their individual needs and stage of kidney function. She is often able to help patients delay the need for dialysis. For those already in kidney failure, she helps patients find optimal wellness with dialysis or a transplant. She holds a naturopathic license in the state of CT and has recently relocated to New Paltz, NY. For more information, visit www.holistic-kidney.com.
NephCure Funded Research: Dr. Michelle Denburg October 3, 2017 by Lauren Eva Dr. Denburg is focused on improving outcomes for pediatric Nephrotic Syndrome patients. In 2012, NephCure and the ASN Foundation awarded Dr. Michelle Denburg, a pediatric nephrologist at the Children’s Hospital of Philadelphia, a research grant to study vitamin D deficiency in the Nephrotic patient. Dr. Denburg is also a Co-Principal Investigator of the NephCure Kidney Network, a patient-reported outcomes registry for individuals with primary Nephrotic Syndrome diseases. We were thrilled to speak with her recently to learn more about her work and the impact that the NephCure-ASN grant has had on her research. Dr. Michelle Denburg NKI: In 2012 you received the NephCure-ASN award for your research on vitamin D deficiency in the nephrotic patient. Can you tell us a little bit about your work that NephCure has helped fund? Dr. Michelle Denburg: There are two studies that were related. One was an ancillary study to NEPTUNE, where we analyzed NEPTUNE baseline samples, measuring vitamin D metabolites and their hormonal regulators. We were looking at the relationships between what we already know in terms of Chronic Kidney Disease (CKD) and vitamin D, but specifically in terms of proteinuric glomerular diseases: the impact of proteinuria and relating some of the abnormalities of vitamin D metabolism to biopsy data and gene expression from the biopsies. The other study is a trial of vitamin D supplementation in patients with Focal Segmental Glomerulosclerosis (FSGS) and other glomerular diseases with persistent proteinuria—basically, treatment resistant patients. [editor’s note: The Nephrotic Syndrome Study Network, or NEPTUNE, is a long-term observational study that was formed to help understand the biology behind Nephrotic Syndrome. NEPTUNE has gathered health data and biological samples from close to 2,000 glomerular disease patients nationwide. Researchers can apply for grants, called “ancillary studies,” to conduct research on this de-identified patient data. Besides having helped fund the creation of NEPTUNE, NephCure also now helps provide the funding that make a number of the ancillary studies possible.] NKI: I know this work has not yet been published, but is there anything from those studies that you can share with us at this time? Dr. Denburg: There are some important things that we are going to be able to demonstrate and report. It’s fairly novel that we have measured vitamin D levels in the blood as well as the expression of vitamin D related genes in the kidney of people with glomerular disease. A lot of what we know about vitamin D metabolism comes from animal models. The fact that we have the NEPTUNE patients’ biopsy data and can relate the gene expression of these enzymes that are involved in vitamin D metabolism to their serum levels—this is highly novel from the research side. From the patient and clinician side, this is the largest study of vitamin D related mineral metabolism in a glomerular cohort. The prior literature is small case studies—this study included several hundred people. NKI: Do you think this work will change how patients are treated in their doctors’ offices? Dr. Denburg: I can’t comment too much on the results of these studies which have not been published yet, but the findings could have important clinical implications. I think the nephrology community may need to consider updating our guidelines on vitamin D replacement in nephrotic patients. Our current guidelines are based on CKD in general. In other words, there is no guideline for patients with glomerular diseases who may have normal kidney function but a lot of proteinuria, or patients who have glomerular disease and CKD. And we know that patients with glomerular disease in particular have several obstacles to bone health. One of my motivations behind this project is my interest in what we can modify to improve bone health in children and adolescents. Many of our patients are being exposed to a lot of steroids over time, and this is over the same period of time that they’re accruing the vast majority of their skeletal mass: about 90% of the skeleton is laid down before age 18. I’m interested in learning what we can do to modify and improve bone health in the face of therapies and illnesses we can’t avoid—that is, until we find a cure. NKI: How do we separate the way steroid use affects bone health for glomerular disease patients to how having CKD in general affects bone health? Dr. Denburg: I don’t know that glomerular patients need to be considered separately so much as have their unique risk within the CKD population considered. By definition, even someone with normal renal function who has glomerular disease is at CKD stage 1. At a certain point, everybody starts losing bone. What kids come away with in terms of their skeleton by the time they enter the adult world is a huge determinant of their later fracture risk and other skeletal burden over time. You can never get that opportunity to address bone health back. You do accrue some cortical mass until age 30, but the majority of what you have is what you can accrue in your skeleton by age 18. Children and teenagers with glomerular disease have unique risk factors: high dose and long term steroid therapy, abnormalities in vitamin D metabolism, ongoing, persistent, heavy protein losses, and inflammation. There are a variety of risk factors that we can hopefully address. NKI: The computable phenotype is another project I know you’re working on, and it sounds like it could be a game-changer. What is your role in that project and what about it excites you for the future of glomerular disease? Dr. Denburg: That’s a very exciting avenue of research. Much of my effort on that is supported by the NephCure Kidney Network. The computable phenotype is a way of identifying patients with glomerular disease through electronic health records (EHRs). It’s being developed in collaboration with PEDSnet [a large clinical data research network, composed of eight health institutions], so it represents over 5 million children and adolescents. The idea is that by running a computer programming code with essentially the push of a button, you can very rapidly say, here are the approximately 3,000 kids who have glomerular diseases across PEDSnet. And this is not static data, this is real life clinical care data. You could run the programmatic code again three months later and identify new cases. This is opposed to the traditional method where someone is sitting and going through the charts at each institution, which is not very time or cost effective. The idea is that this is a means of rapid cohort identification. You can do observational studies on this population’s de-identified data. Or, with regulatory approval, you can contact patients and invite them to be in observational studies and clinical trials. You can also do trials in a more pragmatic way: you can invite patients to participate in a study where they don’t necessarily have to be followed by a typical regimented protocol with extra clinical visits, which is very laborious and cost-intensive. Instead, using this method, if we wanted to do a larger vitamin D study, we could consent individuals for a study and say, we’re going to randomize you to a group that either gets a lot of vitamin D or a group that gets a little vitamin D, abut then after that all your care is going to be your routine care with your clinician. Instead of having you come to separate appointments to track the effects of the vitamin D levels, we’re going to capture your data in regards to this study through your EHR. And we’ll leave it up to your own nephrologist to follow your levels and change your dosage. That’s what I mean by a pragmatic trial. I should say, the study has to lend itself to that—a high risk, new drug study is never going to be implemented in this manner. NKI: And that more closely mimics real life; how a treatment would be used in real life vs. in a highly-regimented protocol. Dr. Denburg: Right—so you lose a little of the very protocolized follow up, but you gain the real-life applicability and generalizability. NKI: What impact did receiving the NephCure-ASN award have on your research? Dr. Denburg: It was really mission-critical. I was a junior person, two years out of fellowship at that point, and it enabled me to build a research program. It helped me in getting my Career Development (K) Award from the National Institutes of Health, and the combination of those two awards allowed me to develop my research program and to have the ability to pursue multiple directions. I like that I get to do patient-oriented research where I’m directly enrolling patients in studies of vitamin D treatment or assessing bone quality through imaging, but then I can also do studies where I’m accessing robust samples from NEPTUNE and entering this large data world. There are things you can do in each that really complement the other. And it’s the way to push things forward, moving between the analysis of large sources of data and then taking it back to the patient and vice versa. So I’m very grateful for the funding. I feel lucky. As pediatric nephrologists, Nephrotic Syndrome makes up a significant portion of patients we see and treat. Being a clinician who sees these patients really helps in keeping you attuned with what needs to be addressed from the research side—the patient care really drives the research questions. We were delighted to learn more about Dr. Denburg’s research. Check back at www.NephCure.org to stay updated on her soon-to-be published work and other advances in the field. Thank you for your passion and commitment to improving the health of patients with Nephrotic Syndrome, Dr. Denburg! Dr. Michelle Denburg, MD, MSCE, is an Assistant Professor of Pediatrics at the Perelman School of Medicine of the University of Pennsylvania and the Children’s Hospital of Philadelphia. Dr. Denburg’s research focuses on bone and mineral metabolism in childhood kidney diseases, including chronic kidney disease (CKD), glomerular disease, and urinary stone disease. In particular, she has pursued translational work in vitamin D-mediated innate immunity in nephrotic patients and ancillary studies of vitamin D metabolism and vitamin D-binding protein in pediatric patients with CKD. Her collaborative studies have focused on vitamin D metabolism and bone structure in children with CKD, nephrotic syndrome, and inflammatory bowel disease. Dr. Denburg’s study of incident fracture risk in the Chronic Kidney Disease in Children (CKiD) cohort was the first to evaluate the burden of fractures in a large pediatric CKD cohort. She is a co-principal investigator in a project of the CKD Biomarkers Consortium that seeks to identify novel biomarkers for CKD progression in children. She has conducted several population-based studies of fracture risk in chronic diseases and CKD epidemiology using The Health Improvement Network (THIN) Database. She also has led the development of and serves as co-principal investigator of a Pediatric Glomerular Disease Learning Health System (LHS) within the PEDSnet clinical data research network. Dr. Denburg attended medical school at the Weill Medical College of Cornell University and received her Master of Science in Clinical Epidemiology from the University of Pennsylvania.
Potential FSGS Treatment Option To Be Tested In Phase 3 Clinical Trial April 2, 2017 by Chelsey Fix Potential FSGS Treatment Option To Be Tested In Phase 3 Clinical Trial Early in March, Retrophin, Inc. announced plans to launch a phase 3 clinical trial to evaluate a potential therapy for FSGS patients. The therapy, called Sparsentan, successfully completed a phase 2 clinical trial in 2016 with promising results. The phase 2 clinical trial, known as the DUET Trial, showed a significant decrease in proteinuria for patients that received the therapy, and a greater proportion of patients that received Sparsentan during the trial reached partial remission. Retrophin plans to launch the phase 3 trial in the second half of 2017. Phase 3 clinical trials are meant to demonstrate the effectiveness of a drug to determine how valuable it may be in clinical practice. It is the last step of research before a drug becomes approved by the FDA for clinical use. The company is currently working with the FDA to approve the protocol for the clinical trial, which includes using the reduction of proteinuria as an endpoint to demonstrate the therapy’s effectiveness. If approved, Sparsentan would be the first FDA-approved drug for FSGS patients. NephCure will be working closely with Retrophin to bring awareness to this clinical trial and help bring the patient perspective to their research.

NephCure Accelerating Cures Institute: Worldwide Launch and US Expansion March 23, 2017 by Lauren Eva The NACI Network is expanding worldwide to speed more effective treatments to individuals with Nephrotic Syndrome Thanks to a significant funding contribution, we’re proud to announce that the NephCure Accelerating Cures Institute (NACI) Care Network is expanding. An investment from Pfizer’s Centers for Therapeutic Innovation (PFE) and Retrophin (RTRX) will help grow the network from 8 sites to 30 sites worldwide. For patients living with Nephrotic Syndrome, more NACI sites means greater access to specialized care and trial opportunities specific to their unique kidney condition. Equally important, a more robust Network gives families across the globe a hub for community building and support at their individual care sites. NephCure Accelerating Cures Institute Global Trials Network The NACI story began in 2014, when leaders from NephCure Kidney International sought advice from leading medical professionals about ways to get better treatment options to patients faster. That following year, NKI launched NACI in partnership with the University of Michigan. Today, NACI is co-led by veteran representatives from NKI in suburban Philadelphia and an expert team from the University of Michigan, Ann Arbor.

NephCure Funded Research: Dr. Martin Pollak’s Lab January 30, 2017 by Chelsey Fix NephCure Funded Research: Dr. Martin Pollak’s Lab Through generous donations from the NephCure Kidney International community, NephCure has been able to support Dr. Martin Pollak’s kidney disease research at Beth Israel Deaconess Medical Center (a Harvard Medical School teaching hospital) since 2007. Dr. Pollak’s lab works on identifying genetic causes of kidney diseases, like FSGS. They have made some very exciting progress over the past few years, leading to Dr. Pollak’s election into the prestigious National Academy of Sciences in 2014. Dr. Pollak’s research has identified that two common variations in the apolipoprotein L1 (APOL1) gene impart up to a ten-fold increased susceptibility to FSGS among African Americans. African Americans and others of recent African ancestry suffer disproportionately from chronic kidney disease: although they make up 13% of the U.S. population, they represent 35% of all individuals on dialysis. Other researchers have calculated that 1 in 8 African Americans are at risk for developing kidney disease due to APOL1—stark numbers that may indicate that some forms are FSGS would not be classified as a “rare disease.” But the research being done at Dr. Pollak’s lab may one day help prevent treat—and prevent—this disease from occurring. Dr. Pollak was recently featured in an article on SFGate.com as saying that “We want to put our own [kidney disease research] division out of business by preventing this disease to begin with.” We are thrilled to offer a “progress report” on this work directly from Dr. Pollak’s lab. We spoke recently with Andrea Knob, a genetic counselor, clinical research coordinator, and key player in Dr. Pollak’s study, who gave us some background on the work the study is doing, what we can expect from this lab in the future, and how you can get involved in this research yourself. Q: What is the goal of the research being done in Dr. Pollak’s lab? Andrea: The purpose of our study is to learn more about the causes of kidney conditions including FSGS, Nephrotic syndrome, unexplained proteinuria, and renal failure by studying genetics. We identify and study genetic factors that may contribute to the development of these conditions. We hope that this will further the knowledge required for scientists to develop better treatments in the future. Q: What is your role at Dr. Pollak’s lab? Andrea: I am the clinical research coordinator for Dr. Pollak’s lab. With my background in genetic counseling, I help patients and families navigate the research process, assist them in documenting their personal and family health histories, and serve as a resource for any questions surrounding genetics and research. I am the liaison between our patients/families and our physicians/scientists. Q: What do you enjoy about CKD research? Andrea: Every person and family has a story to share, and this information is so valuable and so important. It is amazing to witness this generosity, and to be a part of a team that is so dedicated to making progress in this field. Research answers the questions that otherwise would be left unknown, and that in turn provides hope. Q: What is APOL1? Andrea: APOL1 is one of several genes that we study in the Pollak lab. Variations in this gene have been found to confer resistance to trypanosomiasis, a serious disease in some African regions, and as such these variations have risen in frequency in parts of Africa. We are investigating how these gene variants contribute to kidney disease in persons of African ancestry. Q: Why did the lab decide to focus on APOL1? Andrea: APOL1 is one of several genes that we study as we try to learn more about the causes of FSGS, Nephrotic syndrome, and related conditions in patients and families. Our lab’s interest in the genetics of FSGS led us to explore the basis of the high rate of FSGS in persons of African ancestry. Certain specific variations in the APOL1 gene contribute to this disparity. Q: What impact can diagnosing an APOL1 mutation have on treatments for patients? Andrea: We need to learn more about genes, including APOL1, that may contribute to the development of kidney disease. (We also think there are more to be discovered!) Diagnosing a gene mutation helps doctors determine who might be at increased risk of developing kidney disease. While it may not affect the treatment for patients at this time, the goal is to acquire the information we need about these gene variations in order to develop better treatments in the future. Q: What is involved for patients in this study? Andrea: Participation involves a questionnaire, a saliva sample, and a urine sample (if possible) that can be given from home. (If participants prefer to give a blood sample instead of a saliva sample we can help arrange this.) Q: Who can participate in this study? Andrea: • Anyone with FSGS, Nephrotic syndrome, or unexplained proteinuria • Anyone with a family member who has FSGS, Nephrotic syndrome, or unexplained proteinuria • Anyone with African ethnicity with non diabetic kidney failure • Any healthy individual without kidney disease Andrea Knob – Genetic Counselor and Study Coordinator for Dr. Pollak’s study Q: How do I get more information about the study? Contact Andrea Knob with any study related questions by phone at 617-667-0467 or by email at aknob@bidmc.harvard.edu. You can also read more about the research study by clicking here.
Pharmaceutical Company ChemoCentryx Announces Plans for Potential New FSGS Therapy January 30, 2017 by Chelsey Fix Pharmaceutical Company ChemoCentryx Announces Plans for Potential New FSGS Therapy Late last year, ChemoCentryx announced plans to launch a clinical trial in 2017 to evaluate a potential treatment option for FSGS patients. The treatment option, known as CCX140, successfully completed a Phase 2 trial (testing for safety and effectiveness) that included patients with diabetic nephropathy. ChemoCentryx is hoping that success indicates that CCX140 will be beneficial to FSGS patients. Currently, there are no FDA approved treatments for FSGS. NephCure is dedicated to supporting research efforts that would result in approved treatment options for FSGS patients, and we are excited about the potential of CCX140 to help the patient community. Please make sure to “like” us on Facebook and check our website regularly for updates on this development.
Q&A with Dr. Kopp of the NIH December 1, 2016 by Chelsey Fix Dr. Jeffrey Kopp is a physician and researcher who focuses on FSGS and related diseases. He currently leads a group in the kidney disease section (officially called the National Institute of Diabetes and Digestive and Kidney Diseases, or NIDDK) of the National Institutes of Health (NIH). Dr. Kopp is also working on a new clinical trial for FSGS, MCD, and MN patients at the NIH headquarters near Washington D.C. We had the awesome pleasure of sitting down and catching up with Dr. Kopp about his fascinating job and new clinical trial. Keep reading to learn more, and read about some of his other research projects here. Interview highlights: Dr. Kopp works at the National Institute of Health’s kidney branch, where he studies glomerular diseases such as FSGS and MCD. He also serves as Captain for the United States Public Health Service, and has been deployed to help with medical care during natural disasters. Dr. Kopp is leading a new clinical trial for FSGS, MCD, and MN patients at the NIH studying a compound called ManNAc as a treatment option. ManNAc is a sugar that occurs naturally in your body. Another researcher at the NIH found that mice without ManNAc developed MCD, and adding ManNAc to their diet was helpful in treating it. Therefore, it may be effective at treating MCD, FSGS, and MN in humans (Dr. Kopp describes the full mechanism below—make sure you read the article!) This study requires people to stay at the NIH for 11 days total, but it can be split up into 2 trips. Luckily, there is a lot to do to pass free time you may have at the NIH, including movie marathons, exercise programs, an art gallery, and an in-house business center. Learn more about taking part in the study by clicking here or contacting Emily Brede, RN at emily.brede@nih.gov Full interview: NKI: What is your job at the NIDDK? Jeffrey B. Kopp, M.D. Dr. Kopp: I am fortunate to lead a translational research group at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), which is part of the National Institutes of Health. Our mission is to develop a better understanding of the disease mechanisms responsible for focal segmental glomerulosclerosis (FSGS) and to develop more effective and less toxic therapies. I also serve in the United States Public Health Service, with a rank of Captain. My primary mission at NIH is to carry out basic and clinical research in FSGS. I also deploy for public health emergencies, such as natural disasters. Thus, I participated in the medical response to Hurricanes Katrina and Ike. SIDE NOTE: What is NIH? Dr. Kopp: The NIH is a federal biomedical research facility located in Bethesda, MD. The campus includes a 240-bed Clinical Research Center and extensive outpatient clinics. Every patient who comes to NIH participates in a research protocol. Some protocols involve novel treatments and other protocols involve giving samples for research. NIH physicians may give advice about standard therapies that can be used. There are no charges for any medical care provided by the NIH Clinical Center. NKI: What do you enjoy about CKD research? Dr. Kopp: CKD, and particularly glomerular diseases (such as FSGS), are incompletely understood, and the available therapies are not ideal. I like the challenge of understanding and treating these diseases, and most of all I like the opportunity to improve the lives of patients with these conditions. NKI: The newest clinical trial for FSGS, MCD, and MN patients at the NIH is looking at MaNAc as a treatment option. Why did you decide to study MaNAc? Dr. Kopp: A colleague at NIH developed mice unable to make ManNac. She found that these mice developed glomerular disease soon after birth. This disease resembled a human glomerular disease, minimal change disease. Providing extra ManNAc orally to the mice cured the kidney disease. This prompted the question: can we use ManNAc to induce remissions in our patients? Chemical Structure of ManNAc NKI: What is ManNAc? Dr. Kopp: Perhaps the word sounds to you like manna, the food the Israelites found in the desert and that helped sustain them. There is a tree in Europe that exudes a sweet white resin, similar to the sap of the sugar maple, and people who knew the Bible story called the tree the manna tree. A chemist found a distinctive and novel sugar in the manna resin, and he called the new sugar “mannose”. NKI: Does ManNAc occur naturally in the body? Is it found in food? Dr. Kopp: ManNAc is a natural product and essential for good health. Our food does not contain much ManNAc. Our bodies make ManNAc, which is converted in our cells to mannose. This in turn is converted to sialic acid, which is put on many proteins. All of these are sugars, but they differ from glucose in that they are not related to diabetes and they are present in very small amounts, so that they do not add calories in the diet. NKI: What is the reason for believing that ManNAc might be useful in treating glomerular diseases? Dr. Kopp: Podocytes are cells on the outside of the kidney glomeruli and serve to prevent plasma proteins from leaking into the urinary space. Many patients with glomerular diseases have lost sialic acid from the proteins on the podocyte. We think that providing extra ManNAc might promote the return of sialic acid to podocyte proteins and that this might improve podocyte function. We see some evidence in mouse models of FSGS that supplemental ManNAc in the diet helps treat these mice. NKI: What is involved for patients in this study? Dr. Kopp: Patients will provide their medical records for review by the NIDDK team. We also review the kidney biopsy materials from past kidney biopsy. No kidney biopsy is done as part of this study. If patients appear to qualify for the study, they will come to NIH for an outpatient visit for evaluation and to discuss study participation. NKI: Is travel to NIH paid for? Dr. Kopp: Travel to NIH can be arranged and provided by NIH. If overnight accommodation is needed, NIH can provide this also. NKI: Why are patients required to stay at the NIH during this study? NIH Headquarters Dr. Kopp: The study requires being an inpatient for 11 days, either as a single stay or as two stays of five and six days. The reason for the inpatient stay is allow frequent sampling of blood and urine and for safety, to be sure there are no side effects. NKI: What can patients do with any “free time” during the study? How much free time do you expect patients to have? Dr. Kopp: During the first five days, there are frequent time points for sample collection. During the second six days, samples are needed at 8 am and 8 pm. There is extensive free time that patients can use as they like. There are many activities that can help pass the time at NIH • Patient Computers combination television and computer (with Internet access) at most patients’ bedsides to provide access to games, web browsing, and personal e-mail via the Internet • Patient Library has more than more than 5,000 books, including a selection of current best-sellers, reference, foreign language, large-print, picture, and audio books • Clinical Center’s Fine Art Program has more than 2,000 works of art. Most artwork remains on permanent display throughout the hospital, but there are six galleries on the first floor that change every eight weeks. A walking tour is available to assist patients, caregivers and visitors in their enjoyment of the artwork on display. •Recreation Therapy programs include: o Arts and crafts o Music o Games and sports o Social events o Exercise o A large selection of DVD movies o Instruction in coping skills such as relaxation, enhanced communication, and stress management • Spiritual Care Department offers Catholic, Jewish, Islamic, and Protestant services in the interfaith chapel • Business Center has four PCs and four MACs (all with Internet connection) as well as a combined printer/copier/FAX and telephones are available. NKI: Who can participate in the ManNAc study? Dr. Kopp: We are recruiting adults (age ≥18 years) with a primary glomerular disease, including minimal change disease, FSGS, and membranous nephropathy, and with nephrotic range proteinuria (urine protein/creatinine ratio > 2 g/g). Exclusion criteria include having diabetes mellitus and receiving pulse therapies, such as rituximab. Monetary compensation is provided. NKI: How do I get more information about the study? Dr. Kopp: The study, like all clinical research studies, is described at clinicaltrials.gov. You also contact the study research nurse, Emily Brede, RN at Emily.brede@nih.gov

Q&A With Dyan Bryson from Retrophin May 29, 2015 by Chelsey Fix Recently, we got a chance to chat with Dyan Bryson, the Patient Advocacy Director at Retrophin, Inc. – the pharmaceutical company that is sponsoring the DUET study for FSGS patients. We took this opportunity to ask Dyan why clinical research – and the DUET study in particular – is important for Nephrotic Syndrome patients. Keep reading to see our Q&A session with Dyan! NephCure Kidney International: Why do you enjoy/what inspires you about working in the pharmaceutical industry? Dyan Bryson: I first came into this industry thinking I would stay 3 years, that was almost thirty years ago. I simply fell in love with the industry and its potential to help people. I came in rather naively, and at one point I became completely fed up with the lack of focus on patients. I am now back in love as the industry is finally moving towards fulfilling its potential to really help patients, not just support its brands. I love being in an industry where companies that have awakened to putting the patient at the center of its business are also profitable – doing well by doing good. These companies can be examples to others that this can be done. We have realized that we need to support people after they have filled our prescriptions; we have to develop strategies to support their caregivers; we have to support people by realizing that the therapeutic area our drug may be managing is just one of a whole list of things a patient, a person, has to manage in their lives. NKI: What makes participating in DUET a unique opportunity for the NS community? DB: Participating in a clinical trial, especially DUET, is an opportunity to contribute to the knowledge and health of the community. Of course, I am biased, but as a patient advocate I know that if we truly have a drug that can help patients with this rare condition – a condition that has no existing therapy – it can help so many people in the long run. Participation allows us to collect data that may help other people avoid the current long term outcomes of end stage renal disease and transplant. Although we as the drug maker will profit, so will the community through better quality of life. If you participate you can contribute to bettering the health of others. NKI: Why is it so important for rare disease patients and their families to care about research? DB: Many times it is the family of, or person who has, a rare disease that brings that disease to the attention of researchers. Many times if that interaction did not happen there would be no awareness of the disease and, hence, no research. Rare diseases are not like diabetes – researchers, drug companies understand the impact of diabetes. Payers understand the impact diabetes makes on their bottom line as they pay the costs of diabetes management. All stakeholders have clear incentives to manage the disease better. But for a disease where there is low awareness there is little understanding of the impact on a person’s health, hence little understanding of why to do the research. Patients with a rare disease, and their care partners, are the experts on that disease as they manage it 24/7. They are the ones that can drive the understanding of the disease and interest in doing research on that disease like no one else. I still remember the first time that, as a sales representative, my company brought a patient in to talk about the therapeutic area for which we were about to launch a drug. We all had studied and been tested for months to be certified, to confirm we knew the area well enough to talk about it with the physicians we called on. Now, finally, we were at the launch meeting to get our marching orders and celebrate the launch – fun and work at the same time. So, the patient gets on the stage, we had no idea what we are in for. The patient told their story. Soon we were ALL in tears. That one patient helped us understand why were really there. We understood their day-to-day and now we were on a mission to help. Twenty-five years later I can still see that patient on that stage; that experience informs me every single day. That is the impact of a patient telling their story, motivating and inspiring those who can do something about the disease take action. NKI: What is your suggestion for patients that want to learn more and be more involved in clinical research? DB: I know it can be daunting even to think about participating in a clinical trial. You think you are going to be a guinea pig, I understand and so do many others. There is a tidal wave of information out there that can help understand how trials work and help people to understand the process. The US government has even issued grants to researchers all over the country to figure out how to better inform the public about clinical trial participation (http://www.nih.gov/health/clinicaltrials/index.htm) Certainly on the NephCure site (https://nephcure.org/wp-content/uploads/2014/08/Clinical-Research-one-sheet-9162014.pdf) Also, several healthcare advocacy groups have sites that contain materials in several languages to discuss clinical trial involvement: National Minority Quality Forum “Are you in” Campaign – http://www.nih.gov/health/clinicaltrials/index.htm National Medical Association – Project IMPACT – http://www.impact.nmanet.org/about NKI: What do you want a participant to know before they decide to volunteer for a clinical trial? DB: The managers of clinical trials are usually very good about providing access to information about their trial. Scour the site provided, read the materials you are given before you make a decision. Know that the managers of that trial have had to put the trial protocol, all trial materials through a review of a professional board that understands the therapeutic area for which the trial was designed. This board is called an Institutional Review Board (IRB). The purpose of the IRB is to ensure that all human subject research be conducted in accordance with all federal, institutional, and ethical guidelines. This IRB oversees the entire trial, meets at points throughout the trial and makes independent assessments to ensure the safety and well-being of the study participants. In other words, the drug company or other researchers are running the trial with considerable oversight. The study participant is not on their own.
