A method of treating Niemann Pick in a human patient in need thereof comprising administering a composition comprising a mixture of beta-cyclodextrin molecules substituted at one or more hydroxyl positions by hydroxypropyl groups, wherein:
- the mixture comprises unsubstituted beta-cyclodextrin (“DS-0”), beta-cyclodextrin substituted with one hydroxypropyl group (“DS-1”), and no more than 1.0% beta-cyclodextrin substituted with ten hydroxypropyl groups (“DS-10”), and wherein the composition comprises less than 5 International Units (IU) of endotoxins per gram.
A method of treating Niemann Pick in a human patient in need thereof comprising administering a composition comprising a mixture of beta-cyclodextrin molecules substituted at one or more hydroxyl positions by hydroxypropyl groups, wherein:
- the mixture comprises unsubstituted beta-cyclodextrin (“DS-0”), beta-cyclodextrin substituted with one hydroxypropyl group (“DS-1”), and less than 5% beta-cyclodextrin substituted with nine hydroxypropyl groups (“DS-9”) and beta-cyclodextrin substituted with ten hydroxypropyl groups (“DS-10”), collectively, and wherein the composition comprises less than 5 International Units (IU) of endotoxins per gram.
A method of treating Niemann Pick in a human patient in need thereof comprising administering a composition comprising a mixture of beta-cyclodextrin molecules substituted at one or more hydroxyl positions by hydroxypropyl groups, wherein:
- the mixture comprises less than 0.8% unsubstituted beta-cyclodextrin (“DS-0”), and no more than 1.0% beta-cyclodextrin substituted with ten hydroxypropyl groups (“DS-10”), wherein the composition comprises less than 1.5 International Units (IU) of endotoxins per gram, and less than 0.8% propylene glycol.
