FDA Grants Clearance for Experimental Intrathecal Administration of Cyclodextrin

The FDA has granted clearance of an Investigational New Drug (IND) application for administration of Hydroxypropyl Beta Cyclodextrin (cyclodextrin) into the central nervous systems of two patients with Niemann-Pick Disease Type C.

The cyclodextrin will be given intrathecally (into the space under the arachnoid membrane of the brain or spinal cord), first via lumbar injection, and then into the brain’s ventricle system. Children’s Hospital & Research Center of Oakland, California, issued a press release, which can be accessed from the NNPDF's NewsLine page.

The NNPDF would like to note the following regarding cyclodextrin:

1. Cyclodextrin has shown promise as a potential therapeutic in animal trials. However, issues of toxicity have also arisen.
2. The NNPDF is aware that cyclodextrin is being used on a single-patient Investigational New Drug (IND) basis in the U.S. and in Brazil.
3. More research is needed to understand issues related to drug delivery, efficacy and safety.
4. The NNPDF will keep the NPC community apprised of developments regarding cyclodextrin.
