Free Diagnostic Carrier Screening
for Niemann-Pick Disease Types A & B

Date: March 22, 2017
The Quinn Madeleine Foundation, an LDN-affiliated patient advocacy group, has partnered with the Golden, Colorado-based diagnostic laboratory company Baby Genes Inc. to provide diagnostic carrier screening at no charge to hundreds of people impacted by acid sphingomyelinase deficiency (ASMD), also known as Niemann-Pick disease types A & B, which are severe lysosomal diseases. Niemann-Pick disease type A (NPA) is always fatal by toddlerhood. Providing free access to this test will enable prospective parents to make the best, most informed decisions in their family planning.

The diagnostic carrier screening program is currently open to any family member of an affected child, though it intends to go further in the future. “The long-term goal is to consider the possibility of an ethnicity pattern, identifying a higher-risk general population, and offering more widespread screening,” says Eileen Linzer, Co-Founder & Executive Director of The Quinn Madeleine Foundation. Family members screened are therefore also asked to complete an optional, self-reported “Ethnicity Survey” to assist in this research.

Consensus Conference to Convene for
Cognitive Endpoints in MPS I, MPS II and MPS III

Date: November 16, 2016
Elsa Shapiro, PhD, neuropsychologist and expert in rare pediatric diseases; Mark Dant, president and CEO of the National MPS Society (USA); and Christine Lavery, executive director of the Society for Mucopolysaccharide Diseases in the UK, have planned a program to bring experts together from around the world to establish a consensus for cognitive endpoints in MPS I, MPS II and MPS III. Such endpoints are absolutely essential for conducting clinical trials of potential treatments. The consensus conference will be held December 1-3, 2016 in London.

With support from 18 pharmaceutical companies, more than 80 doctors and psychologists from countries around the world will attend, including China, Egypt, Australia and Japan. The U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) are sending representatives who will present. The consensus proceedings and the selected consensus panel comprised of experts in MPS, statistics and psychological assessments will be facilitated by J.H. van der Lee, MD, PhD, of the Academic Medical Center, Amsterdam, Netherlands. Participants also include the Lysosomal Disease Network’s Dr. Chester Whitley, Dr. Igor Nestrasil and Dr. Julie Eisengart, all of the University of Minnesota. A paper will be published documenting the outcome.

New Peer-Reviewed Article Examines
a Burgeoning U.S. Stem Cell Treatment Marketplace

Date: August 3, 2016
In a currently in-press (and online) article entitled Selling Stem Cells in the USA: Assessing the Direct-to-Consumer Industry in the journal Cell Stem Cell, authors Leigh Turner and Paul Knoepfler “found 351 U.S. businesses engaged in direct-to-consumer marketing of stem cell interventions offered at 570 clinics.” In a careful examination of marketing claims used by these 351 businesses, they found that “U.S. businesses promoting stem cell interventions claim to treat a wide range of diseases and injuries, as well as advertising stem cells for cosmetic applications, “anti-aging,” and other purposes.” In addition to “relatively specialized marketplace niches” such as cosmetic surgery clinics and orthopedic and sports medicine clinics advertising stem cell treatments, “other clinics take a much broader approach and list stem cell interventions for 30 or more diseases and injuries. Such businesses commonly market treatments for neurological disorders and other degenerative conditions, spinal cord injuries, immunological conditions, cardiac diseases, pulmonary disorders, ophthalmological diseases and injuries, and urological diseases as well as cosmetic indications.” The authors wrote that “Many of these marketing claims raise significant ethical issues given the lack of peer-reviewed evidence that advertised stem cell interventions are safe and efficacious for the treatment of particular diseases. Such promotional claims also generate regulatory concerns due to apparent noncompliance with federal regulations.”

They found many instances of stem cell marketing claims directed not at potential patients themselves, but at patients’ caregivers or parents. These included specific marketing claims for stem cell treatments for Parkinson’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis, autism, cerebral palsy, and muscular dystrophy. They found that marketing claims are being asserted for these and “many other conditions for which there is no established scientific consensus that proven safe and efficacious stem cell treatments now exist.” The authors’ concerns are that “This kind of advertising reveals another tangled knot of ethical and legal concerns, as the apparent target audience for such marketed interventions is not adults with decision-making capacity but rather the parents or guardians” of potential patients.

The authors’ in-depth examination of the online information provided by each of the companies they identified led them to conclude that “. . . there are clear grounds for concern that some of the companies we found are not compliant with federal regulations. There are related ethical concerns about information provided to prospective clients and the veracity of marketing claims, the safety and efficacy of advertised procedures, and the risk of physical, emotional, and financial harm to already ill or injured and vulnerable individuals.”

The International Society for Stem Cell Research offers a free downloadable .pdf Patient Handbook on Stem Cell Therapies that is available in English, Dutch, French, German, Italian, Portuguese, Spanish, Turkish, Persian and Japanese.

The REGROW Act, sponsored by Senator Mark Kirk (IL) (U.S. Senate HELP Committee markup (“Amendment 1; document BOM 16344″)), was noted by the authors as “an example of the current push . . . for lowering safety and efficacy standards for adult stem cell-based interventions.” The National Organization for Rare Disorders (as well as the Cystic Fibrosis Foundation, the Friedreich’s Ataxia Research Alliance, the Friends of Cancer Research, Global Genes, the Michael J. Fox Foundation for Parkinson’s Research, the Myotonic Dystrophy Foundation, the National MS Society, the National Patient Advocate Foundation and the Prevent Cancer Foundation) expressed opposition to this proposed legislation (as it is currently drafted) in a letter to Senator Kirk dated May 24, 2016. They wrote, in part, “We are concerned that the REGROW Act as currently drafted could compromise patient safety by providing “conditional approval” to products that simply show “preliminary clinical evidence of safety” as part of Phase I and Phase II trials. We are troubled that these provisions establish a new approval standard that is potentially lower than existing standards. By allowing products to be marketed as approved therapies, this implies to patients a high level of approval which is not warranted given the current requirements in the bill. We believe this proposed legislation may result in grave consequences for patients.”

New Developments in Farber Disease Research

Date: July 18, 2016
Enzyvant Sciences is a new pharmaceutical company that is the product of two companies: Roivant Sciences and Plexcera Therapeutics, LLC. They have formed this joint venture to focus on the treatment of Farber disease, one of the lysosomal diseases.

At Enzyvant Sciences, it is thought that the recombinant human acid ceramidase (rhAC) program will benefit from the continued involvement of the experienced medical and scientific team from Plexcera, while gaining the pharmaceutical development expertise and financial support of Roivant. Developed in the lab of Professor Edward Schuchman, MPh, PhD, the enzyme replacement therapy rhAC showed promising results in a mouse model of Farber disease. It was initially licensed by Mount Sinai Innovation Partners, part of the Icahn School of Medicine at Mount Sinai, to Plexcera Therapeutics, LLC, prior to the formation of Enzyvant.

rhAC is based on more than 20 years of research conducted by Dr. Schuchman and Erich Gulbins, PhD, from the Center for Medical Biotech at the University of Duisburg-Essen, Germany. Dr. Gulbins identified a central role for excess ceramide accumulation in cystic fibrosis and some other pulmonary diseases. rhAC may eventually be put to other therpautic uses in addition to Farber disease. Dr. Schuchman’s laboratory has been studying the biology of lysosomal enzymes, genes and diseases for more than 25 years, achieving a number of breakthroughs towards the development of novel therapies for lysosomal disorders. For example, Dr. Schuchman’s team was the first to isolate genes encoding lysosomal enzymes linked to Niemann-Pick disease types A and B, mucopolysaccharidosis type VI (MPS VI), and Farber disease.

Dr. Edward Schuchman said, “I am very excited about the future of rhAC. Similar to other enzyme replacement therapies, rhAC has the potential to be a transformative therapy for patients afflicted with Farber disease, a population with clear unmet medical needs.” Dr. Schuchman is Francis Crick Professor of Human Genetics and Vice Chairman of Research, Department Of Genetics and Genomic Sciences; and Professor, Department of Gene and Cell Medicine, at the Icahn School of Medicine at Mount Sinai in New York City. Dr. Schuchman will continue to play an integral role in the development of rhAC. Dr. Schuchman is on Plexcera’s Board of Directors and owns an equity interest therein.

MPS I to be added to the newborn screening panel

Date: Feb 17, 2016
The Secretary from the Department of Health and Human Services has provided final response to the ACHDNC for both X-ALD and MPS type I. She has agreed with the ACHDNC and has added both to the recommended uniform screening panel (letters here and here). The Minnesota Commissioner of Health will be notified as well so that this information can be used while he deliberates the recommendations made at the October meeting. This means that Minnesota, and a number of other states, will have the mandate to add MPS I to the newborn screening panel, each child born in the state being screened as a newborn infant.
