Orphan Drug Designation for Cyclodextrin | NPC

This week the FDA has stated formally that they see promise in the use of Cyclodextrin in treating Niemann-Pick Type C (NPC) by granting its “Orphan Drug Designation”.

In January of 1983, the Orphan Drug Act (ODA) was passed into law in the United States with consistent pursuit by the National Organization for Rare Disorders. The ideal behind this is to encourage pharmaceutical companies to look into smaller markets with development of drugs for orphan diseases. Niemann-Pick Type C (NPC) certainly falls into this category (around than 500 diagnosed ever worldwide). The benchmark on how to determine an orphan disease is one that affects less than 200,000 people.

As Nadine Hill, director of family services of the National Niemann Pick Disease Foundation (NNPDF) stated in an email to families this week, “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.”

Chemical structure of the three main types of cyclodextrins.

Cyclodextrins are a sugar compound which was first described in 1891 by A. Villiers. Currently the food industry uses cycodextrins in preparing cholesterol free products. The concept is to help reduce the intercellular cholesterol that becomes the main culprit in NPC. By reducing the size of the lysosomes and in theory reducing cholesterol, it can help prolong the life of a child or adult suffering from the death sentence of NPC. Although there currently is no formal clinical trial, these actions are a step in the right direction. There still is a lot of unknowns and work that will need to take place.

Behind the push to get to this point is Chris & Hugh Hempel who has twin daughters suffering from NPC. In conjunction with other NPC families they formed their own Virtual BioTech they named S.O.A.R. (Support of Accelerated Research). Through the work of much collaboration, this has shown to help move research quicker.

As of today there is no known cure or effective treatment for Niemann-Pick Type C. The future outcome looks bright even though time is not on our side. The Niemann-Pick Children’s Fund looks to provide support in the areas of research, education/awareness, and family support through existing channels.

Why refer to it as the “Childhood Alzheimer’s”?

You possibly can recall someone you knew that suffered from Alzheimer’s disease. Currently 5.3 million Americans are living with this progressive and fatal brain disease with no cure (www.Alz.org). Alzheimer’s is progressively devastating in how it destroys brain cells, causes loss of memory (progressive dementia), and problems with intellectual functions that affect many of the things you and I take for granted. Alzheimer’s is the seventh leading cause of death in the United States (www.Alz.org).

In comparison to Niemann-Pick Type C Disease (NPC), it has maybe less than a 100 people currently living in the U nited States. Many sources state that 500 cases have been diagnosed ever worldwide. That’s not exactly as common of disease as Alzheimer’s.  NPC is described as a genetic degenerative neurological  disorder that mostly strikes during childhood that stores fatty lipids in the brain, liver, spleen, and bone marrow because of the cells inability to metabolize cholesterol. Although uncommon, adult onset can take place with NPC. Outcome is also fatal with no cure.

Whether it is Niemann-Pick Type C Disease (NPC) or Alzheimer’s, they are extremely saddening to experience as a loved one. One affects mostly older adults and the other strikes predominantly in adolescents. Regardless, a main symptom in each disease is progressive Dementia along with similar pathological features that include the loss of intellectual function.

The question seems to arise often regarding why would you refer to Niemann-Pick Type C Disease (NPC) as the “Childhood Alzheimer’s” when they are technically two separate diseases? Touche’, great point Dr. Watson. My wife Jennifer absolutely hates when the two are referred to one another. I on the other hand am absolutely fine with the comparison and title.

When you tell someone about NPC, they kind of give you that “deer in the headlights” look along with the “side head nod” like a puppy. For any of you in sales or marketing the first thing you are taught is to make an impact statement to gain attention or some type of understanding of what your speaking about. When you say the “Childhood Alzheimer’s” people can instantly relate to someone or to a situation where they’ve heard about Alzheimer’s or Dementia.

Overall if you explain in a way that they are two separate diseases that share some similarities, you should be able to paint a mental picture for your audience. In no way do I feel by using this reference that it confuses nor threatens anyone. Just explaining what NPC is, is confusing enough. How can you make it any more confusing for people? Seriously.

You as a parent are the biggest advocate for your children. We need to let people know about this horrible disease. I believe it holds keys to other diseases affected by the storage of cholesterol in cells. Please visit our website www.NPCFund.org or my family’s personal page www.BriParDun.com.

Why Rare Diseases OUR Important

How many times have you been looking for something at your house but you accidentally find something you previously were missing? Wouldn’t it be a shame if the prize you were seeking was within reach but you discounted that it could be that easy? What if understanding Niemann-Pick Type C disease opened up the door to help millions of Americans with other disorders involving cholesterol? Of course nothing in life is easy nor will it always be within reach. With being human comes the tendency to make oversights.

It has been almost 13 years in July 2010 that the NPC1 gene, on Chromosome 18 for Niemann-Pick Type C was shared with the world on its discovery. This was a huge step and monumental discovery with associating cholesterol with a certain gene/chromosome at that time. To arrive at this point, it took decades of work which shed an abundant light into how a cell metabolizes cholesterol. In short, Niemann-Pick Type C causes progressive deterioration of the nervous system by blocking the movement of cholesterol within cells.

From a press release dated July 10, 1997 from Bethesda, MD:

“This discovery is an excellent example of how research on rare brain disorders often pays off in other ways,” says Zach W. Hall, Ph.D., Director of the National Institute of Neurological Disorders and Stroke (NINDS). “By identifying this gene, we not only take a crucial step forward in understanding this devastating disorder, but also gain insights into problems that affect every one of us.”

In 2001, cardiovascular disease was responsible for more than 39 percent of all deaths in the United States (American Heart Association: Heart Disease and Stroke Statistics 2004). Atherosclerosis is a disease where plaque builds up in your arteries. We all know those aren’t important to our lively hood at all. OK, just joking but plaque is made up of fat, calcium, cholesterol, and other substances found in our blood that over time builds up but hardens in the passage ways of our arteries. Imagine if you’re driving through a two way tunnel but one side is now closed off?  It would be kind of hard to get through to the other side in a timely and relaxing manor with additional objects in your way? Just like that situation, this affects how we get our blood to important areas in our bodies. With millions of people dying each year, this is a huge number of people. What if Niemann-Pick Type C could provide some insight?

Other diseases such as Adult onset Alzheimer’s, Stroke, Cystic Fibrosis, Duchenne Muscular Dystrophy, and even HIV-Aids will benefit from the research into Niemann-Pick Type C. Did you know that children can experience dementia to? Crazy to imagine because most of us think that only our elderly family members get that! With the combination of deaths due to these diseases, could you imagine if we had a more collaborative research environment? Unfortunately big companies aren’t going to sacrifice revenue opportunities to help a blip on the radar screen but they will invest if they see it helping thousands of people; this means a return on their investment. This reality is sad but true.

Rare diseases OUR important to you, me, and everyone we know. Each of us has a Chromosome 18 that is vital to us being a living human being.  I encourage you to help out in some way. That could be donating to several charities that fund research for NPC like the National Niemann Pick Disease Foundation, Ara Parseghian Medical Research Foundation, Hide and Seek Foundation or the Niemann-Pick Children’s Fund. That could be becoming and advocate in lobbying our government for better health care. It could be you just passing the word and spreading awareness.

We all are in this together and have been affected in some way by one of the diseases mentioned in this post. One person can make a difference in the world and that person could be you.
