What is Niemann-Pick Type C?

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.
