The Latest Research
The Canadian Chapter of the National Niemann-Pick Disease Foundation (CCNNPDF) is a sister chapter to the National Niemann-Pick Disease Foundation (NNPDF) (U.S.) and receives administrative support from the NNPDF. Money raised through the CCNNPDF is invested in Niemann-Pick Disease research through the NNPDF's research program with guidance from the NNPDF's Scientific Advisory Board (SAB), Board of Directors, and Research Committee. This partnership helps eliminate redundancy and maximizes the impact of research dollars. (Tammy Vaughan, chair of the CCNNPDF, serves as secretary of the NNPDF, and is on the NNPDF's Research Committee.)
The research funded by the NNPDF is made possible in great part due to the efforts of our NPD families and their extended support network via local community-sponsored events. The NNPDF is truly grateful for this support.
In 2014, the National Niemann-Pick Disease Foundation Board reviewed its research funding strategy and has produced a new strategic plan for research. Account was taken of the needs of our Membership; current knowledge in the field of Niemann-Pick Disease; the funding strategies of other NPD organizations; and the advice and expertise of the members of the NNPDF's Scientific Advisory Board.
As a result we are pleased to announce that the NNPDF will fund Pre-Doctoral, Post-Doctoral and Early career investigator fellowships in all areas of promise - basic, translational and clinical research- with regards to Niemann Pick Disease.
The NNPDF strives to enable promising new researchers to make a career in the field of Niemann-Pick Disease, thus providing for a new generation of scientists to accelerate the pace of NPD research.
"The NPD community is one of the most collaborative there is. The level of idea/data sharing among scientists is remarkable. We are also a model for other rare disease with respect to our ability to accelerate work at the bench to therapeutics. And much of this had been made possible by the family-researcher partnerships that have sustained this work over the past 20 years." - Dr. Dan Ory, Current NNPDF Scientific Advisory Board member & past SAB Chair (Sept. 2007 ~ Jan. 2014)
A key element to the foundation research strategy for both the NNPDF & CCNNPDF is the ability to track funds raised within the communities of our family membership. Great care is given to identify monies received at the NNPDF & CCNNPDF Central Offices through family fundraising efforts so that a specific designation by disease type and a restriction towards research can be made. The NNPDF & CCNNPDF are proud to ensure our NPD family membership that 100% of the funds raised through their community events are directed towards NPD research!

Safety and Tolerability of Within-Patient Dose Escalation
Presentation by: Dr. Melissa Wasserstein
Melissa P. Wasserstein M.D.
During the 2014 Annual Meeting of the American Society of Human Genetics (ASHG), held from October 18th-22nd in San Diego, California, Dr. Melissa Wasserstein M.D. was honored to give a presentation on the results of the safety and tolerability of the enzyme replacement therapy (ERT) 1b clinical trial being funded by Genzyme, a Sanofi Company.The key information noted within the abstract was that: “ The dose escalation regimen was well tolerated, with all patients reaching the maximum dose of 3.0 mg/kg. No serious or severe adverse events or deaths were reported. Related AEs consisted predominantly of infusion-associated reactions, the majority of which were mild and resolved without sequalae. A positive response to treatment with rhASM was observed in liver sphingomyelin content and several exploratory efficacy parameters, including spleen and liver volumes, pulmonary function testing, lung imaging, lipid profile, and quality of life assessments.”

to further research in connection to Niemann-Pick Type C & the Ebola virus.
Dear NNPDF Families and Friends,
Right on the heels of October 2014 as GLOBAL Niemann-Pick Disease Awareness Month, a news article has been posted in the Wall Street Journal highlighting the unique connection between NPD Type C and Ebola. Wall Street Journal Medical writer, Amy Dockser Marcus, who previously wrote an in-depth article on the Hugh and Chris Hempel family, their twin daughters, Addi & Cassi and their journey with NPD Type C, brings the research around full-circle.
Hugh Hempel noted, "In 2009 we donated our cells (a little punch biopsy under our arm) to a non-profit bio-bank in order to make it easier for scientists to research NPC. Never imagined that Ebola researchers would take our cells and use them to discover that our RareDisease could enlighten a treatment for Ebola... Check out the Wall Street Journal Article about this amazing connection."
The members of the NNPDF Scientific Advisory Board have indicated for years that the NPC gene is so very complex and likely holds the key to answers for a wide array of diseases and illnesses.

Update from Dr. Forbes D. Porter, MD, PhD
Senior Investigator, PDEGEN, NICHD
Program Head, PDEGEN, NICHD
Clinical Director, NICHDThe NNPDF central offices received the following update from Dr. Forbes D. Porter to share with the NPC community with regards to recent developments in reference to the Histone Deacetylase Inhibitors (HDACi) ~ vorinostat clinical trials for NPC adults.
We are pleased to inform the NPC community of an upcoming clinical trial at the NIH to study the safety and tolerability of vorinostat in adults with Niemann-Pick disease, type C1. We plan to begin enrolling patients in September 2014.
This clinical trial is an open label study for 12 patients. “Open label” means that every patient will get vorinostat. There is no placebo, or sugar pill, in this study. Patients will come to the NIH for a total of 3 visits - at baseline, 3 months and at 6 months for this trial. Each visit will last for about 7-10 days. Patients will start taking the study drug while they are at the NIH and will continue taking the study drug when they return home. They will also need to have blood drawn for safety labs every two weeks between visits while they are at home. After the 6 month visit, they will stop taking the study drug and they will be done with the trial.Vorinostat is a pill that is taken by mouth. The purpose of this study is to test the safety and tolerability of vorinostat when it is given to adults with NPC1. Patients will have blood drawn and will have a lumbar puncture (spinal tap) to collect spinal fluid at each visit to measure how much of the drug is absorbed. Patients will also have tests of hearing, speech, swallowing and movement.
For the full press release and more information on the clinical trial and eligibility criteria for NPC adult patients, please refer to the NNPDF HDAC Inhibitor clinical trial page.
Dateline: September 12th, 2014
Ara Parseghian Medical Research Foundation (APMRF):The FDA has granted an Investigational New Drug exemption to the APMRF that will allow us to study the safety and potential biochemical efficacy in adult patients with NPC1. The study will enroll 12 NPC1 patients. Although the IND exemption does not allow us to test vorinostat in children with NPC1, this exemption will save significant time and expense in obtaining proof of concept data. Working together, this collaborative group hopes to advance our understanding of the potential of an HDACi to treat individuals with NPC. Greg Crawford, Dean of the Notre Dame College of Science, in conjunction with APMRF have raised $500,000 to facilitate this work. Merck has graciously agreed to provide the drug supply for the trial.

*Cyclodextrin and HDAC Inhibitor*
Update from Dr. Forbes D. Porter, MD, PhD
Senior Investigator, PDEGEN, NICHD
Program Head, PDEGEN, NICHD
Clinical Director, NICHD
The NNPDF central offices received the following update from Dr. Forbes D. Porter to share with the community in regards to recent developments in both the Cyclodextrin and new Histone Deacetylase Inhibitors (HDACi) clinical trials.
The TRND team continues to work to determine if cyclodextrin is a safe and effective therapy for children and young adults with Niemann-Pick Disease, type C1. This trial was initially started in January 2013 using Ommaya reservoirs; however, after three patients we had to stop the trial due to complications. The trial was revised to administer the cyclodextrin by lumbar intrathecal infusion (spinal tap). We were able to resume the trial in September of 2013 and to date we have enrolled twelve patients in whom we have studied cyclodextrin doses between 50 and 400 mg. Some of the initial biomarker results look promising and we expect to obtain results from additional biomarker testing over the next few months. From a safety perspective we are still concerned about ototoxicity (hearing loss) and we are working to try to better understand this issue. Concurrent with this first trial we are working on a number of options that would support a phase II/III trial that would try to show that cyclodextrin has clinical benefit. This second trial will need to be multisite and multinational.
For more information about the Cyclodextrin Clinical Trial, visit the Cyclodextrin page.
In addition to cyclodextrin, we are also exploring the potential use of histone deacetylase inhibitors (HDACi) to treat NPC1. The Maxfield and Sturley research groups showed that HDACi can reduce cholesterol storage in cells that have been cultured from NPC1 patients. Over the past year we have been working to establish a proof of concept clinical trial of HDAC inhibition in NPC1. A proposal to evaluate HDACi in NPC1 was awarded one of the first U01 grants (Drs. Maxfield, Ory and Porter) designed to promote extramural utilization of the NIH Clinical Center ( http://www.nih.gov/news/health/mar2014/nichd-13.htm ). This collaboration has now been expanded this intramural/extramural collaboration to include investigators from Notre Dame (Drs. Helquist and Wiest), Broad Institute (Dr. Holson) and Mayo Clinic (Dr. Patterson). This effort is being supported by Notre Dame College of Science and the Ara Parseghian Medical Research Foundation. The initial drug to be tested will be vorinostat. Vorinostat is approved by the FDA for the treatment of cutaneous T-cell lymphoma. Since this is a proof of concept trial and the safety of this drug in NPC subjects is not likely to differ significantly from patients with cutaneous T-cell lymphoma who have failed alternative chemotherapy, we were able to obtain a waiver of the requirement for an Investigational New Drug application for the testing of vorinostat in adult subjects with NPC1. The NICHD Institutional Review Board (IRB) has approved a protocol to test the safety and efficacy of vorinostat in a cohort of 12 adult NPC1 subjects and we are currently working on IRB approval for a second site at the Mayo Clinic. This will be a phase I proof of concept trial that will focus on safety of HDACi in NPC1 subjects and determine if HDAC inhibition has a desirable biochemical effect in white blood cells. Although we still have a number of issues to resolve, it is our goal to initiate this protocol this fall.

Acid Sphingomyelinase Deficiency (ASMD) Development Efforts
June 13th, 2014
Dear NNPDF Families and friends,
The NNPDF Central Offices received the following update from Genzyme (a Sanofi Company) in reference to the current Enzyme Replacement Therapy clinical 1b phase trial provided on June 13th, 2014:
" Genzyme, a Sanofi company, is pleased to update the Niemann-Pick disease patient community on the progress of efforts to develop a potential therapy for acid sphingomyelinase deficiency (ASMD, also known as Niemann-Pick disease Types A and B).
Genzyme completed a Phase 1b trial in Niemann-Pick disease Type B adult patients in January 2014. The Phase 1b trial evaluated the safety and tolerability of an investigational enzyme replacement therapy recombinant human acid sphingomyelinase (rhASM) when administered once every 2 weeks. Five adult patients with Niemann-Pick B disease were enrolled and completed the trial at two study centers, Mount Sinai in New York, NY, US, and St. Mary’s Hospital in Manchester, UK. At this point in time, we are reviewing and preparing the final analyses of the Phase 1b trial. The results of the Phase 1b trial will allow us to develop and plan future studies and to have a discussion with regulators such as FDA and EMA concerning our next step in the process.
While Genzyme continues to evaluate the results of the Phase 1b trial and prepare for meetings with the regulatory authorities, Genzyme continues to make progress preparing for a Phase 2 trial to further evaluate the safety and efficacy of different doses of rhASM when administered once every two weeks for one year. The Phase 2 study will be a multi-center, international, 1-year placebo-controlled trial to investigate the safety and efficacy of rhASM in adults with Niemann-Pick disease Type B. Participant enrollment for the Phase 2 study will begin after the results of the Phase 1b clinical trial have been fully evaluated, we have had the opportunity to discuss the results with regulatory authorities, and the trial sites are activated.
Genzyme remains committed to the Niemann-Pick community and will keep you updated as our development program continues. "
The NNPDF will continue to keep you updated as we receive further updates pertaining to this important research and clinical work on behalf of our Niemann-Pick Disease type A and B (ASMD) community.

NIH Update on NPC Cyclodextrin TrialDear NNPDF Families and Friends,
We received the following update from Dr. Denny Porter with reference to the NIH/TRND Cyclodextrin Clinical:
Dr. Porter advised:
“We have hit a potential safety issue with the HPBCD trial. The initial two kids who received the 300 mg dose demonstrated a grade 1 high frequency hearing loss on safety testing. Grade 1 is the lowest level of severity. Five other children have been exposed to the 300 mg dose. We do not yet have safety testing on this group. We will obtain this information over the next 3-4 weeks. We do not yet know if this is an idiosyncratic (the initial two kids are siblings) reaction or if this is going to be a general issue. We have engaged the IRB and safety committee. We will be engaging the FDA. Our goals are to determine if we have a general safety issue and to figure out the best path forward. Beyond the statement that a problem with hearing has been encountered and we are trying to figure out the safest and best way forward, there is not much that we can say. There are multiple hypothetical paths forward at this time and the final plan is subject to information that we don’t have yet and input from other groups. The uncertainty will remain for much of the next month. We are not halting the trial.”Denny
Forbes D. Porter, MD, PhD
Senior Investigator, PDEGEN, NICHD
Program Head, PDEGEN, NICHD
Clinical Director, NICHDAs Dr. Porter noted, all involved will need to wait until the children in the trial return back to the National Institutes of Health in Bethesda, Maryland for further testing before the multiple agencies involved will be able to make any additional determinations on how to proceed. Of course, of utmost concern is that any action will ensure that “first and foremost” ~ the health and safety of all involved is in the forefront.
Thank you to all for their continued expertise, support and involvement in these efforts.
Kind regards,

From the Wall Street Street Journal Blog :
For years, Christopher P. Austin has been trying to develop a way for science to build a better partnership with patients.
Dr. Austin is director of the National Center for Advancing Translational Sciences (NCATS), part of the NIH. NCATS is trying to find ways to get new treatments and cures for diseases delivered to patients faster.
At NCATS, Dr. Austin heads a state-of-the-art lab that uses robots to search for treatments.
In recent years, families of patients with rare diseases have made their way to the NIH to watch the robots at work in the $20 million, 30,000 square-foot system that includes refrigerators, automated incubators and computers. Machines work around-the-clock, testing hundreds of thousands of compounds against a variety of mostly rare diseases.
One of the first parents to visit was a woman whose college-age son had a rare cancer. During a tour in 2006, Dr. Austin told her that instead of 17 years to develop a new drug, he hoped that the lab could cut the time to 10 years.
“ ‘I love your technology,’ ’’ Dr. Austin recalled the woman saying. “ ‘I love your robots. I love this fancy stuff. But for my child and this disease, 10 years, 15 years, isn’t going to work. Isn’t there something else we can do?’ ’’
It is a question he hears again and again. There are roughly 7,000 known diseases; only about 500 have a treatment. Even with robots working day and night, Dr. Austin said, the arithmetic is discouraging.
We will bring you the link once it is available tomorrow so you can join in! Stay tuned!

Dear NNPDF Friends and Families,
Edward H. Schuchman, PhD, an esteemed member of the NNPDF Scientific Advisory Board Member (SAB), along with Robert J. Desnick, MD, who also had previously served on the NNPDF SAB, both of the Department of Genetics and Genomic Sciences at the Icahn School of Medicine at Mount Sinai recently received “Inventors of the Year” award from the New York Intellectual Property Law Association (IPLA) for their work on Niemann-Pick disease.
The award pays tribute to individuals who have made worthwhile contributions to society by applying inventiveness to progress in science.
Their discoveries led to a drug for the treatment of Niemann-Pick Disease Type B ~ an orphan disease where the patient's cognitive and motor skills are severely impacted and leads to multiple complications; Dr. Schuchman and Dr. Desnick also discovered the genetic mutation causing the disease, and how to screen for it. Niemann-Pick Types A and B are rare inherited lysosomal storage disorders that cause debilitating health complications and are often fatal, especially for children. There are currently no approved treatments for Niemann-Pick A or B.
The work of Dr. Schuchman and Dr. Desnick has also led to a potential treatment, an enzyme replacement therapy, which is currently being tested in a Phase 1b trial with Genzyme Corporation in patients with Niemann-Pick B. A Phase II trial is being planned.
The Board, patients and family members of the National Niemann-Pick Disease Foundation wish to wholeheartedly echo these notes of congratulations and acknowledgement to Dr. Schuchman & Dr. Desnick regarding the excellence of their work, in addition to their unending commitment and devotion to the patients and families affected by ASMD (NPD Type A & B). You are truly heroes in our eyes.

NIH Announcement - Cyclodextrin Trial Update~ January 31st, 2013 ~ |
Dear NPD Community,The NNPDF central offices received the following update on the Cyclodextrin trial from the NIH Research Team.
"The NIH cyclodextrin trial has started and the first patient will receive the drug on Monday 2/4. We are very excited to get started and to get data that will direct future studies of cyclodextrin in NPC. We have been in contact with many families and would like to provide an update about the trial screening process.
The patients in this trial are grouped into "cohorts" of three patients each. Because we did not know exactly when we would be able to start the trial, the first three patients were selected because they live relatively close to the NIH or were able to come to the NIH with very little notice (less than 2 weeks in one case). Only the first 3 patients have been scheduled. We have not yet filled the remaining slots for the trial.
The FDA asked us to start at a lower dose than we initially proposed. The initial data from these first three patients will determine what exactly we will do next. We decided that we will need to re-screen patients when we are ready to schedule the next cohort (patients 4, 5 and 6), in order to make sure they are still eligible. This will also need to happen again with the last 3 patients. We have a screening log of all individuals who we have screened and will be in touch with families when we are prepared to schedule the remaining slots in the trial.
We would like to thank you for your continued patience and we apologize for any delays in returning phone calls or emails. We are doing our best to get this trial going as quickly and safely as possible so we can answer questions about cyclodextrin in NPC. Please do not hesitate to contact us with additional questions.
The NIH NPC Research Team"

National Niemann-Pick Disease Foundation Research Post-Doctoral Fellowship Funding Announcement~Oct/Nov 2012~ |
The National Niemann Pick Disease Foundation (NNPDF) has chosen to fund post doctoral fellowships for the past several years. These fellowships support a post doctoral fellow to work on a research project in the field of Niemann-Pick Disease for a period of two years. The NNPDF has utilized strategies to allocate funds raised by NPD families by disease type to support these specific NPD disease focused fellowships.
In the past several years, NNPDF has been able to fund a number of fellowships for Niemann-Pick Disease Type C. These are called the Peter G. Pentchev Research Fellowships and the NNPDF in conjunction with the Canadian Chapter of the National Niemann-Pick Disease Foundation (CCNNPDF) are currently funding the work of five (5) Peter Pentchev fellowships.
This year we were able to establish a fellowship for Acid Sphingomyelinase Deficiency (ASMD; i.e., Types A and B Niemann-Pick Disease) research entitled the Edward H. Schuchman Research Fellowship for ASMD Niemann Pick Disease. We received 5 strong applications for the fellowship and I am pleased to announce that the first Edward H. Schuchman Fellowship has been awarded to Dr. Lluis Samaranch Gusi (sponsor Dr. Krystof S. Bankiewicz, MD, Ph.D.) at the University of California San Francisco.
This fellowship research project is entitled: “AAV9 mediated human acid sphingomyelinase expression in the non-human primate brain; Preclinical development of gene therapy for Niemann-Pick Disease Type A”. The goal of this project is to develop a treatment for the neurological consequences of Niemann-Pick Type A Disease. This project will evaluate the feasibility of delivering an adeno-associated virus encoding human acid sphingomyelinase globally into the brain by injection of a vector into the brain and/or the spinal canal.

Planned Phase I Study of Cyclodextrin (HP-β-CD) for NPC1 Disease
Since our last communication in September 21, 2012, the National Institutes of Health Therapeutics for Rare and Neglected ~ Niemann-Pick Disease Type C team has continued to move forward in the preparation of the Phase I Study of Cyclodextrin (HP-b-CD) for NPC1 Disease.
The TRND NPC Team is pleased to announce that the Investigational New Drug (IND) application for intraventricular hydroxypropyl-β-cyclodextrin (HPBCD) was filed with the FDA today, November 14th, 2012. This was a major effort by multiple research laboratories, several NIH institutes, Johnson and Johnson and a team of pharmaceutical and regulatory consultants. This effort would not have been possible without the assistance of the many patient support organizations.
Our ultimate goal is to develop a safe, effective and accessible therapy for all individuals with NPC1. The IND filing is a major step in this process, but just one of the initial steps. We are hopeful that the very promising preclinical findings in mice and cats will translate to an effective therapy in individuals with NPC1. The goal of this first trial is to rapidly determine a safe and biochemically effective dose of HPBCD. These data are critical to the proper design and execution of a multicenter efficacy trial that will allow this drug, if determined to be safe and effective, to be approved by regulatory agencies, and ultimately to be made available to all NPC1 patients.
We appreciate the ongoing support from the NPC community and will continue to update the community on this trial.

U.S. FDA Safety and Innovation Act Signed: Monumental Step Toward Development of
Safe and Effective Treatments for Americans With Rare Diseases
The FDA Safety and Innovation Act (FDASIA), signed by President Obama July 9, contains the most groundbreaking measures for rare disease patients and their families since the Orphan Drug Act of 1983, according to the the National Organization for Rare Disorders (NORD).
"This legislation represents true progress for people with rare diseases, who often struggle to access treatments for their disorders," NORD President and CEO Peter L. Saltonstall said.
Specific to the rare disease community, the Act provides the following:
- accelerated patient access to new medical treatments
- the development of Humanitarian Use Devices (medical devices for small patient populations)
- accelerated development of "breakthrough therapies" -- those that show early promise
- enhanced FDA consultation with rare disease medical experts
- a rare pediatric disease priority review voucher incentive program
- resolution of conflict-of-interest issues that kept voices of rare disease medical experts from being heard

Update from Genzyme on Acid Sphingomyelinase Deficiency (ASMD) Clinical Trials
Genzyme, a Sanofi company, is continuing efforts to develop recombinant human acid sphingomyelinase (rhASM) for the potential treatment of the non-neurological manifestations of acid sphingomyelinase deficiency (ASMD, also known as Niemann-Pick disease Types A and B).
We are actively preparing for a Phase 2 clinical trial of rhASM in Niemann-Pick B patients to evaluate the safety and efficacy of different doses of rhASM when administered once every two weeks. In preparation for the trial, we have sought feedback from the FDA, are evaluating potential study centers worldwide, and are assessing our short- and long-term manufacturing plans.
We are also beginning to schedule the long-term follow-up visits for the natural history study of Niemann-Pick B patients that began in 2001 in the US, France, Italy, Germany, and Brazil. These vists are expected to yield important information about disease progression in the absence of treatment and may be included in a potential drug application filing in the future.
Our entire organization, from the Genzyme rare disease team to our colleagues at Sanofi, is committed to the development of rhASM and to addressing the unmet medical need of patients with ASMD.
We appreciate the support of the global Niemann-Pick disease community and will provide another update as soon as we are able to confirm a start date for the Phase 2 clinical trial.

Blood Draws to Support NPC Research
Two blood draws coordinated by NNPDF family volunteers will support research into a blood test to diagnose Niemann-Pick Disease Type C (NPC). The diagnostic blood test is expected to provide a faster, easier and more comfortable method than the current skin punch biopsy diagnostic test.
Karen Quandt, mother of 15-year-old Ty Quandt (NPC), organized a blood draw earlier this month to collect samples from healthy (non-NPD) teens to serve as pediatric control samples (see photos above). Rebecca Spencer, mother of 6-year-old Johnathan Spencer (NPC), is organizing a blood draw for April, in which samples from younger non-NPD children will be drawn for the same purpose.
The research is being done at the National Institutes of Health (NIH) in Bethesda, Maryland, and at Washington University School of Medicine in St. Louis, Missouri.
Thank you to Karen, Rebecca, the volunteers, and especially the donors, for participating in this important project!

NIH Clinical Research Trials and You
|
The NIH (U.S.) recently announced the launch of a new Web site titled NIH Clinical Research Trials and You , geared for those considering participating in a clinical trial.
According to the press release announcing the new site , "Clinical trials are essential for identifying and understanding ways to prevent, diagnose, and treat disease. Research has shown that among the greatest challenges to recruitment of volunteers is the lack of general knowledge about what trials involve, where they are carried out, and who may participate."
This new Web site aims to help potential participants learn about clinical trials and make an informed decision about whether they should take part. The site includes sections on "The Basics," "Volunteer Stories," "Researcher Stories," "Finding a Trial." Also, "For Health Care Providers," "Educational Resources," a glossary of terms, and much more.

Latest Update on Planning for NIH's Clinical Trial of Cyclodextrin |
The NIH/TRND NPC team met again with representatives of the FDA on Tuesday, December 13, to discuss plans for the upcoming clinical trial of cyclodextrin, and we are pleased to be able to share the update below.
NNPDF members can be assured the foundation will continue to keep families up-to-date on information about plans for this and all clinical trial as details become available. Updates will be posted here to the NewsLine page, as well as to the Facebook page and the listserv groups.
For more information about TRND (Therapies for Rare and Neglected Diseases program) and the six pilot projects selected (including NPC), see this press release from NIH .
Update from the December 13 meeting:
Dear families and friends of the NPC community,
The collaborative group planning a cyclodextrin clinical trial at the National Institutes of Health (NIH) for the treatment of Niemann-Pick type C (NPC) disease met with the Food and Drug Administration (FDA) on Tuesday, December 13, 2011 as a follow up to the recently held November pre-IND meeting. On November 1, we met with the FDA Review Division staff to discuss the proposed development plan for cyclodextrin and needs for the IND application package.
Representatives from the Therapeutics for Rare and Neglected Diseases (TRND) group at the NIH, as well as several NPC researchers, Johnson & Johnson, and consultants from RRD International, LLC, participated in this meeting.
While the November meeting focused on the drug safety and toxicology data, the purpose of the December meeting was to discuss the proposed clinical trial design. Overall, the feedback from FDA was very positive and their comments and guidance will assist us in the generation of an IND application that is agreeable to FDA, thus allowing us to move forward with the initial clinical trial as soon as possible.
Preclinical toxicology and safety studies in animals are ongoing, and additional studies will be initiated shortly. These required nonclinical studies will guide the selection of drug doses for the initial trial and will provide essential safety information. In the upcoming months, we will be evaluating these study results and will incorporate them into the IND application and initial clinical protocol, which will then be submitted to FDA and the NIH Institutional Review Board (IRB). Once we have agreement from FDA and approval from the NIH IRB, we can share the specific details of the initial clinical trial, such as patient inclusion/exclusion criteria.
We are very excited about the progress we have made thus far and are encouraged by our recent meetings with FDA. We understand that the community is eager to start this initial trial as soon as possible and we do not have time to waste. Following the meeting, we believe that FDA shares our sense of urgency and we are grateful that they are willing to work closely with us to get this important initial trial started. As always, your support of NPC research is the final piece that will help us impact this disease. Thank you for your enthusiasm, your patience, and especially for trusting that we are making every effort to help individuals and families affected by NPC.

Ebola Research finds Link to NPC1 Protein
Two recent publications from researchers based at MIT and Harvard report that the NPC1 protein is an essential factor in allowing infection by the deadly Ebola virus. The MIT team lead by Brummelkamp et al. used a genetic screen to identify mutant cells that were unable to support Ebola infection. They identified a panel of genes related to uptake into endosomes, most notably NPC1. Cunningham and colleagues at Harvard used small molecule inhibitors to prevent Ebola infection, and in collaboration with Dan Ory at Washington University, demonstrated that the inhibitors were disrupting interaction between a viral protein and NPC1. These findings lay the groundwork for development of new drugs to prevent Ebola infection. The studies will spur further interest in the NPC1 protein, and could lead to new insights into its function.

Potential use of HDAC (histone deacetylation) inhibition as a treatment of NP-C disease. |
|
Two independent studies suggest a new pathway for intervention in NP-C disease that is FDA approved for treatment of other diseases. Here, senior authors of these papers, Dr. Sturley (long-time member of the NNPD's Scientific Advisory Board) and Dr. Fred Maxfield, describe their findings and optimistically but cautiously describe the potential of this strategy as a therapy. The modification of proteins after they are synthesized is a common and critical regulatory aspect of many cellular processes. Acetylation of proteins such as histones, changes their net charge from positive to neutral or negative. This reduces the ability of the histone to associate with DNA and thus changes the expression of numerous genes. The removal of acetylation (i.e. histone deacetylation, HDAC), reverses this effect. Treatment of human cells derived from NP-C patients, with HDAC inhibitors markedly improves cholesterol (1, 2) and sphingolipid (2) abnormalities of these cells. These observations were made with newer HDAC inhibitors that can be used at concentrations 1000-fold lower than that suggested for valproate, which reportedly was ineffective in some NP-C patients. One HDAC inhibitor is currently FDA-approved for treatment of cancer. Several others are in clinical trials for cancer and other diseases, including neurodegenerative conditions such as Huntington’s disease and ALS. Because of the existing safety testing and evidence of entry into the brain, there is the potential to enter into the clinic with these leads relatively quickly. However, several critical issues still need to be addressed. For example, it appears that the mechanism may be related to increased expression of the NPC1 protein (1). Consequently, it is not yet known which mutations (i.e. which patients) will respond effectively to HDACi treatment. Most importantly we need to determine if these compounds affect the function of the brain in NP-C patients or animals. Studies to address these issues are in progress.

Wall Street Journal Health Blog Article:
|
In an article by Amy Dockser Marcus, the Wall Street Journal's Health Blog reported on a paper recently published in the Journal of Neuroscience on the use of cyclodextrin to treat NPC in mice. The paper's authors, led by Dr. John M. Dietschy of the University of Texas Southwestern Medical School, report that the treatment not only kept the mice alive, but prevented the cognitive decline of NPC.
“It will be a very influential paper in the field,” scientist Daniel Ory [Chair of the NNPDF's Scientific Advisory Board] tells the Health Blog. Ory ought to know: he is the principal investigator on an NIH grant focused on getting cyclodextrin from the lab into NPC patients. He’s also working closely with NIH’s Therapeutics for Rare and Neglected Diseases program, which selected NPC and cyclodextrin as one of its pilot projects to attempt to repurpose drugs for use in rare diseases.
The NNPDF hosted a conference call on May 2 which addressed plans for an upcoming clinical trial using cyclodextrin in NPC patients. In addition to Dr. Ory, the conference call included information about the clinical trial from Dr. Forbes "Denny" Porter of the National Institutes of Health. Text of the conference call (pdf) .

NIH to Develop Clinical Trial Utilizing Cyclodextrin
|
The National Institutes of Health (NIH) (U.S.), in collaboration with the Therapeutics for Rare and Neglected Diseases Program (TRND), is developing a clinical trial utilizing cyclodextrin for Niemann-Pick Type C patients. The clinical trial is in the planning phase and many criteria must be met and numerous approvals granted before the trial can take place. Dr. Porter, a Senior Investigator at the NIH, and Dr. Ory, NNPDF Scientific Advisory Board Chair, are working collaboratively to bring this trial to our NPC patient community.
In early May, the NNPDF will host a conference call with key constituents and researchers, for all interested parties in the NPC community to learn more about the work being done at the NIH. This conference call will include information pertaining to the development of plans for a cyclodextrin trial.
As a date and details for the conference call are confirmed, the NNPDF will work to update and inform our NPC family membership with the call-in information, agenda outlines and topics of discussion. We anticipate that after the presentation, the conference call format will allow participants to submit questions to the speakers/researchers.
Further updates on the clinical trial will be presented at the NNPDF Family Support and Medical Conference in Norfolk, Virginia, July 28th - 31st. Dr. Porter and Dr. Ory will answer questions pertaining to the clinical trial and will report up-to-date information about the trial at the conference.

Paper Published on Study of Histone Deacetylase Inhibitor for Use in NPC
University of Notre Dame Press Release Claims Breakthrough
A paper claiming a breakthrough in the fight against Niemann-Pick Disease Type C (NPC) appeared in a recent issue of Proceedings of the National Academy of Sciences (PNAS). The paper, coauthored by Olaf Wiest and Paul Helquist of the University of Notre Dame and Frederick Maxfield of Cornell University, says the use of an unspecified histone deacetylase inhibitor corrects the damage done by the genetic disorder NPC and allowed once-diseased cells to function normally. Follow this link to view an abstract of this paper at PNAS: http://www.pnas.org/content/early/2011/03/15/1014890108
To help understand the press release issued by Notre Dame on March 21, the NNPDF consulted three respected experts in Niemann-Pick Disease Type C: Dr. Dan Ory of Washington University, Dr. Marc Patterson of Mayo Clinic, and Dr. Denny Porter of the National Institutes of Health. Follow this link to view the Notre Dame press release dated March 21, 2011: http://www.eurekalert.org/pub_releases/2011-03/uond-bin032111.php
Daniel Ory, M.D., Washington University School of Medicine, and Chair of the NNPDF’s Scientific Advisory Board, responded to our inquiry:
The results are promising, but represent an early step in the process of identifying effective compounds for NPC. More cell studies are needed to understand the mechanism [and] mouse studies should be pursued….there is a long history of compounds that are effective in reducing cholesterol in cultured cells but do not have benefits in animal models, so we should be cautious in extrapolating such results to humans.
Marc C. Patterson, M.D., Chair of the Division of Child and Adolescent Neurology at Mayo Clinic, also a member of the NNPDF’s SAB, further cautioned against making premature assumptions:
The work was done in cultured fibroblasts, so one should be very cautious about extrapolating these data to animals or humans. Moreover, the work was done in cells expressing one or two I1061T NPC1 mutations, and may not be relevant to other mutations; it was not effective in an NPC2 mutant cell line. Of note, the late Dick Pagano showed dramatic reversal of trafficking abnormalities and filipin staining in NPC fibroblasts in which rab 7 and 9 were overexpressed, but much more modest results in transgenic mice with NPC1 mutations and rab overexpression.
Mouse studies could certainly be justified, but it would be premature to assume that this approach will be applicable in humans with NPC.
Forbes “Denny” Porter, M.D., Ph.D., of the National Institute of Child Health and Human Development at the National Institutes of Health (NIH), stated, “It is always good news to have a potential new approach to treating NPC. Cells are the starting point, but to translate this to a potential therapy more work needs to be done.”
The paper by Wiest, Helquist and Maxfield does not name the specific histone deacetylase inhibitor. Histone deacetylase inhibitors (referred to as HDAC inhibitors) are a class of compounds that interfere with the function of histone deactylase. HDAC inhibitors have a history of use in psychiatry and neurology as mood stabilizers and anti-epileptics.
One HDAC inhibitor, valproic acid, was considered as a possible treatment for NPC, but results have not been overly promising.
Yiannis Ioannou, Ph.D., Department of Genetics and Genomic Sciences at Mount Sinai School of Medicine, also a member of the NNPDF’s SAB, made the following statement regarding his recent study of valproic acid and NPC:
We have just concluded our mouse studies on valproic acid and have evaluated its effect on cells from a number of NPC patients and on the NPC mouse. Unfortunately, the results are not great.
- For NPC patient cell lines we have treated six different lines with valproate. Some cells responded positively; i.e., the cholesterol storage was cleared but some lines were completely resistant to the treatment. Upon analysis of our data it became clear that if the patient has a relatively mild mutation then they would respond to valproate, whereas if the mutation is more severe, then the cells don’t respond.
- With respect to the mouse study, we have treated about 25 mice with daily dosing of valproate. We can extend the life of these mice by about 10%. The mice live about 122 days on average vs. 108 days for the untreated mice.
At this point we don’t think that valproic acid would be beneficial for NPC patients.
Some years ago, valproic acid was given to a few NPC patients, including Stacey Vorpahl (1985-2004), the daughter of Gary and Barbara Vorpahl of Fort Atkinson, Wisconsin for the treatment of seizures. Barb, Vice Chair of the NNPDF Board of Directors, recently posted to the NNPDF listserv group about her family’s experience with valproic acid (as Depakote):
We did have Stacey on valproic acid (Depakote) for seizures when she first started having seizures. This was at age seven. Once she started Depakote we saw a rapid decline. One of the side effects is muscle weakness. It can also actually cause seizures at higher doses. She was on Depakote for about a year. She quit talking, needed a wheelchair, could no longer sit up or roll over by herself. We didn’t think she would survive to age 8 at her rate of deterioration. We thought the decline was from NPC but after comparing notes with other parents and seeing strange seizures that their children were also experiencing when doses were increased, we decided to gradually wean her off of Depakote and try another seizure medication. It was like bringing her back from the dead. We saw her strength start coming back, alertness level [sic], her talking never resumed but she did have strength to walk with assistance. I know others have had success with valproic acid but for Stacey it was a very negative experience. I was very surprised when I saw research coming out on valproic acid. It may work in mice but it certainly did not help our daughter even controlling seizures.
This summary was compiled by the NNPDF Central Office staff with thanks to the members of our esteemed Scientific Advisory Board. (March 31, 2011)

New Test Promises to Find Fatal Diseases Before Conception
Test Could Determine if Parents Are Carriers for Genetic Diseases
A new DNA test has been developed to identify carriers of 580 of the most severe inherited childhood diseases. Announced in the journal Science in Translational Medicine , the test uses genetic sequencing to identify recessive mutations.
The new test could be used before a couple decides to become parents. Currently, preconception testing is recommended for just a few diseases, such as Tay-Sachs and cystic fibrosis, and can cost as much as $2,000.
According to abcnews.go.com , this new carrier screening may cost less than $400, and may become available in the near future. Clinical work will be done at Children's Mercy Hospital in Kansas City, Missouri. The test will likely be a blood test and later a simple swab of the cheek. Egg and sperm banks may be the first industry to adopt the testing to screen potential donors.

Oxidative Stress in Niemann-Pick Disease Type C
Molecular Genetics and Metabolism recently published a new article titled, " Oxidative stress in Niemann-Pick disease, type C ," from authors Fu R, Yanjanin NM, Bianconi S, Pavan WJ, Porter FD.
The article is summarized as follows:
Oxidative stress is caused by an imbalance between the production of reactive oxygen and a biological system's ability to detoxify the reactive intermediates or easily repair the resulting damage. Increased oxidative stress has been reported in human NPC1 mutant fibroblasts and in tissues from Npc1 mutant mice. However, oxidative stress in NPC patients has not been established. This study demonstrated increased oxidative stress in NPC patients.
Blood samples from 37 children and adults with NPC were tested. Compared to control values, the NPC samples showed significant decreases in both the fraction of reduced coenzyme Q10 (CoQ10) and Trolox equivalent antioxidant capacity (TEAC). Reduced CoQ10 functions as an antioxidant protecting cells from oxidative damage. Trolox is used as a reference substance to measure the combined antioxidant capacity in biological specimens. Both findings are consistent with increased oxidative stress in NPC. However, supplementation with CoQ10 was not effective in correcting the decreased fraction of reduced CoQ10.
Demonstration of increased oxidative stress in NPC patients provides both a rationale and the biomarkers necessary to test the efficacy of antioxidant therapy in NPC.

Suzanne R. Pfeffer of the Stanford University School of Medicine, Department of Biochemistry, provided us with this
APMRF Scientific Conference Overview
.
The APMRF conference abstracts, with additional notes by NNPDF Board Chair Karen Quandt, are available here .
The NNPDF holds the greatest respect and gratitude toward the APMRF (Cindy Parseghian, President) and the NPC research advancements it has spearheaded over the years. The work of all involved at the APMRF has opened many doors and established new and innovative ways to encourage more communication between scientists.
The APMRF has been instrumental in bringing together NPC researchers from around the world to share in their knowledge and findings. In addition, the foundation has played an integral part in drawing new researchers into the NPC scientific field. Without these efforts much of the progress we have seen in NPC would not have occurred.
We are all truly grateful for the work of the APMRF and the entire Parseghian family in memory of their children ~ Michael, Marcia and Christa.

2010 Peter G. Pentchev Postdoctoral Fellowships Awarded
The NNPDF is pleased to announce the recipients of the
2010 Peter G. Pentchev Postdoctoral Research Fellowships
.
The research projects of Dr. Nicholas Cianciola of Case Western Reserve University, and Dr. Dorothea Maetzel of the Whitehead Institute for Biomedical Research, were selected through an application process which included reviews by the NNPDF's Scientific Advisory Board (SAB). The SAB then made recommendations to the NNPDF's Research Committee and Board of Directors .
Dr. Dan Ory, Chair of the NNPDF's Scientific Advisory Board summarized the two selected projects:
1. Nicholas Cianciola - "Activation of an alternative cholesterol homeostatic mechanism in NPC"
Dr. Cianciola’s project builds upon an exciting observation he made while a graduate student and will explore the role of a viral protein in facilitating movement of cholesterol from lysosomes. The research has the potential to identify new therapeutic targets to stimulate release of cholesterol from lysosomes in the absence of a functional NPC1 protein.
Dr. Cianciola's sponsor at the School of Medicine, Case Western Reserve University (Cleveland, OH) , is Dr. Cathleen Carlin.
To read Dr. Cianciola's Lay Summary of the project, click
here
.
2. Dorothea Maetzel - "In Vitro modelling of Niemann-Pick type C Disease Using Patient-Specific Induced Pluripotent Stem Cells"
Dr. Maetzel’s project will lead to development of pluripotent stem cells from human NPC mutant fibroblasts. The stem cells will then be used for high throughput assays to identify small molecules that can correct the cholesterol accumulation in the NPC cells. Development of these cell lines will allow allow testing of whether the genetic defect can be corrected in the stem cells, which could have therapeutic potential.
Dr. Maetzel's sponsor at the Whitehead Institute for Biomedical Research (Cambridge, MA) is Dr. Rudolf Jaenisch.

Hearing on Rare and Neglected Pediatric Diseases
On Wednesday, July 21, the US Senate Committee on Health, Education, Labor, and Pensions held a hearing entitled, "Treating Rare and Neglected Pediatric Diseases: Promoting the Development of New Treatments and Cures."
A panel at the hearing featured Dr. Jesse Goodman, chief scientist at the FDA, and Dr. Alan Guttmacher, the new director of the National Institute of Child Health and Human Development of the National Institutes of Health. A second panel included representatives from various non-governmental organizations.
Participants advocated for a range of solutions, including increased federal funding for clinical registries, more stringent guidelines for patient registries, and establishing a federal policy in regards to orphan drugs and rare diseases; all of which would have an ultimate goal of encouraging researchers to develop drugs for those rare diseases that currently have none.

FDA grants “Orphan Drug Designation” to Cyclodextrin for treatment of
Niemann-Pick Disease Type C
Due to the efforts of Hugh and Chris Hempel, Dr. Caroline Hastings and Ron Browne, an application to the Food and Drug Administration requesting “Orphan Drug Status” for Cyclodextrin has been approved.
What exactly does that mean for our NPD community? It is important to emphasize that an Orphan designation does not make any assessment at all on how the drug works in clinical trials, whether it is safe or effective in patients, nor whether it will ever be commercially available – the Orphan designation’s main purpose is to make the development of the drug more financially viable for the developer.
Please visit our cyclodextrin page for a bit of background and glossary terms that will help you to understand this latest development.

April 13, 2010: In response to recent questions from NPC families, the NNPDF asked Dr. Dan Ory, Chair of the
Foundation's Scientific Advisory Board
, about the possibility of using either stem cells or gene replacement as therapies for Niemann-Pick Disease Type C.
Here is Dr. Ory's response:
I know of no evidence that gene replacement therapy is effective for NPC disease. There may be work going on in this area, but there is nothing promising on the horizon.
[ Re. the suggestion ]... that stem cell therapy is efficacious in the NPC1 mouse model... I am not aware of this. In fact, in my own lab I replicated the experiments done by labs claiming to show benefit from stem cell transplantation, only to find that the protocols actually worsened symptoms and shortened the life span of the mice. Any claim that with our current technology that stem cell transplantation is beneficial should be met with extreme skepticism.

NIH and FDA Announce Collaborative Initiative
Partnership to Speed New Treatments to Patients
The U.S. Food and Drug Administration and the National Institutes of Health have announced an initiative intended to accelerate the timeline between scientific breakthrough and the availability of innovative medical therapies to patients.
From the NIH's press release:
The initiative involves two interrelated scientific disciplines: translational science, the shaping of basic scientific discoveries into treatments; and regulatory science, the development and use of new tools, standards and approaches to more efficiently develop products and to more effectively evaluate product safety, efficacy and quality. Both disciplines are needed to turn biomedical discoveries into products that benefit people.
As part of the effort, the agencies will establish a Joint NIH-FDA Leadership Council to spearhead collaborative work on important public health issues. The Joint Leadership Council will work together to help ensure that regulatory considerations form an integral component of biomedical research planning, and that the latest science is integrated into the regulatory review process.

More Details on Cyclodextrin from Dr. Dietschy's Lab
Work continues in Dr. John Dietschy's lab at UT Southwestern (Texas), aimed at understanding the way cyclodextrin works in NPC cells and the effect of its administration at various stages of disease in the NPC1 mouse. A recent paper shows reversal of cholesterol storage and decreased inflammation in a variety of tissues 48 hours after administration of cyclodextrin. However, lifespan of the NPC1 mouse is extended only following very early administration of the compound. Research continues.

Edinburgh Neuroscience Christmas Lecture 2009
While the following link will take you to a fairly technical overview , for those who are interested in the potential for stem cell therapies, it is a fascinating lecture. Two University of Edinburgh, Scotland, professors provide a review of the current status of developments in stem cell research and future applications to clinical medicine. Their focus is on neurological disorders such as Amyotrophic Lateral Sclerosis (ALS or Lou Gehrig disease) and Parkinson disease. Their initial work focuses on study of genes that are active in regenerating brain tissue, something that does happen, but which becomes less efficient with age. They look at targeting expression of these genes through use of medications in order to carry out brain repair. They also look at use of stem cells, both embryonic stem cells and those created from adult cell lines. Note that this is an overview and some issues, such as the difficulties encountered with aging of "embryonic" stem cells produced from adult cells, are not discussed.

New Paper on Cyclodextrin
"Cyclodextrin overcomes deficient lysosome-to-endoplasmic
reticulum transport
of cholesterol in Niemann-Pick type C cells."
Research from the lab of Drs. Michael Brown and Joseph Goldstein was recently published online (in advance of print publication) in a highly regarded
scientific journal, The Proceedings of the National Academy of Science. The abstract, or summary, of the work is available at:
http://www.ncbi.nlm.nih.gov/pubmed/19884502?itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum&ordinalpos=1
The paper provides details about the processing of cholesterol in NPC1-deficient cells if it can be released from the lysosomes, and about how
cyclodextrin assists in moving cholesterol out of the lysosome and into the
cell cytoplasm, where they hypothesize that it will be less damaging to cell function.
The authors note that additional study is needed to understand
whether there are specific conditions under which the cyclodextrin works to
move cholesterol, and the specific way it works, which is not yet
understood.
The full paper should be available in about six months. We
look forward to reading more about this work in the future.

Study Conclusively Ties Rare Disease Gene to Parkinson's Disease
Dr. Ellen Sidransky’s Research Regarding Gaucher and Parkinson Disease
"An international team led by a National Institutes of Health researcher has found that carriers of a rare, genetic condition called Gaucher disease face a risk of developing Parkinson’s disease more than five times greater than the general public. The findings were published ... in the New England Journal of Medicine.
In previous studies, several genes have been linked to Parkinson's disease. However, researchers say their work conclusively shows that mutations in the gene responsible for Gaucher disease are among the most significant risk factors found to date for Parkinson's disease. The discovery was made by investigators from the National Human Genome Research Institute (NHGRI) and the National Institute on Aging (NIA), both parts of the National Institutes of Health, in collaboration with scientists from 16 research centers across four continents.
'This analysis illustrates how studying a rare but important disorder, like Gaucher disease, can provide powerful clues about more common disorders, such as Parkinson's disease," said NHGRI Scientific Director Eric Green, M.D., Ph.D. "Understanding the genetic basis of rare conditions can thus provide insights into normal cellular and biological processes, which in turn may lead to improved diagnostic and therapeutic strategies.' "
Read the full article here: http://www.nih.gov/news/health/oct2009/nhgri-21.htm
Dr Sidransky is also interested in investigating the possible association between NPC and three specific neurodegenerative disorders - Parkinson disease, ALS (Lou Gehrig disease), and early-onset Alzheimer disease (diagnosed before the age of 65). The aim would be to see if a relative of an NPC patient who has any of these other neurodegenerative diseases also carries an NPC mutation.
