A singular focus on cholesterol modulators

Cholesterol plays vital roles in our body. As an essential building block of cell membranes, cholesterol is fundamental for biosynthesis, integrity, and functions of the biological membranes. It is also crucial for synthesis of hormones, vitamin D, and other substances. However, too much cholesterol can increase your risk of developing various cholesterol-driven diseases such as cardiovascular disease, chronic kidney disease, and neurodegenerative disease. Unfortunately, drugs that can directly target cholesterol and regulate its metabolism is not available in the market, leaving great unmet medical need.

Renatus is focused on developing cholesterol modulators that directly target excessive cholesterol and improve its metabolism, therefore normalizing dysregulated cholesterol homeostasis.


Cyclodextrin is a ring-structured molecule, composed of six to eight glucoses linked together in a cyclic shape. The cavity of the ring structure exhibits hydrophobicity, whereas the surface exhibits hydrophilicity. Such a ring structure allows it to host hydrophobic molecules such as cholesterol inside the cavity and solubilize them.


Cyclodextrin regulates cholesterol homeostasis


Increased cholesterol influx or decreased cholesterol efflux can induce accumulation of excessive cholesterol within cells, which hampers proper cellular functions and leads to various cholesterol-associated diseases. Cyclodextrin helps maintenance of cholesterol homeostasis by promoting cholesterol metabolism pathways. 

Cyclodextrin functions in various organs

The ability of cyclodextrins to regulate cholesterol homeostasis has shown to help treat cholesterol-associated diseases in various organs throughout our body including brain, heart, aorta, kidney, and others.


Cyclodextrin in clinical trials


Hydroxypropyl-beta-cyclodextrin (HPβCD) is a derivative of beta-cyclodextrin. HPβCD is more soluble and less cytotoxic than natural beta-cyclodextrin. HPβCD is being investigated in clinical trials for diseases including Niemann-Pick type C, Alzheimer's disease, and focal segmental glomerulosclerosis.


Despite the promising effects of cyclodextrin on regulating cholesterol homeostasis, ototoxicity can occur following peripheral or central nervous system-directed delivery of HPβCD. It has been experimentally shown in various animal species that both routes can result in the preferential loss of outer hair cells (OHCs) in the cochlea. Ototoxicity caused by loss of OHCs can cause permanent hearing loss, which should be managed with hearing aids.
