Orphan Drug Designation for Cyclodextrin | NPC

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.”

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.
