DelveInsight’s “Niemann-Pick Type C Disease – Pipeline Insight, 2025” highlights an emerging portfolio of candidates targeting multiple disease pathways—ranging from small molecules that restore lipid homeostasis to gene therapies designed to correct NPC1/NPC2 mutations. Cyclodextrin-based agents, histone deacetylase (HDAC) inhibitors, and oxysterol derivatives are in advanced stages of development, aiming to enhance cholesterol clearance and reduce neuroinflammation. Novel approaches such as intrathecal delivery of 2-hydroxypropyl-β-cyclodextrin (HPβCD), ASOs targeting NPC gene expression, and adeno-associated virus (AAV)–mediated gene replacement are showing promise in clinical and preclinical studies.
The 2025 pipeline reflects a strategic shift from symptomatic management to precision interventions that directly address NPC pathophysiology. Growing regulatory support for rare disease innovation, coupled with international patient registry data, is accelerating trial design and recruitment. With advances in targeted small molecules, RNA-based therapeutics, and gene therapy platforms, the coming years may redefine the standard of care for Niemann-Pick Type C, offering renewed hope to patients and families facing this devastating condition.

Niemann-Pick Type C Disease Overview
Niemann-Pick Type C (NPC) disease is a rare, inherited neurodegenerative disorder characterized by the body’s inability to properly metabolize cholesterol and other lipids within cells. This leads to the accumulation of toxic substances in various organs, including the brain, liver, and spleen, causing progressive neurological decline, liver dysfunction, and respiratory issues. Symptoms typically appear in infancy or childhood but can manifest at any age, and include difficulties with movement, learning disabilities, seizures, and psychiatric problems.
NPC is caused by mutations in the NPC1 or NPC2 genes, which play critical roles in lipid transport within cells. Currently, there is no cure for the disease, but treatments focus on managing symptoms and slowing disease progression. Research and clinical trials are ongoing to develop therapies that can improve outcomes for affected individuals, including the use of drugs aimed at reducing lipid accumulation or enhancing cellular function.

Niemann-Pick Type C Disease Treatment Analysis: Drug Profile
Trappsol Cyclo: Cyclo Therapeutics, Inc.
Trappsol Cyclo, developed by Cyclo Therapeutics, Inc., is a proprietary formulation of hydroxypropyl beta cyclodextrin that has demonstrated promising results in multiple clinical studies for managing cholesterol transport. Acting as a substitute for the defective NPC1 protein, its cyclic structure helps transport accumulated cholesterol out of cellular lysosomes, allowing it to be processed and eliminated from the cells. Trappsol Cyclo is currently undergoing clinical trials for the treatment of Niemann-Pick Disease Type C1 (NPC), a rare, progressive, and fatal genetic disorder, as well as Alzheimer’s disease, a progressive neurological condition in which elevated cholesterol is also a known risk factor. The drug has received FDA Fast Track Designation for NPC treatment and has been granted Orphan Drug status by both the FDA and the European Medicines Agency. It is presently in Phase III clinical development for Niemann-Pick Type C Disease.
