ABOUT US

​​CALDRE is a Switzerland based

biotech spin-out focussed to

revolutionize the way cholestatic-

and fibrotic diseases are treated.

​

We develop precise, liver-directed

GalNAc-siRNAs to restore bile flow

and prevent fibrosis - placing

CALDRE in the fast-growing

RNA-therapeutics segment of

biotech.

THE PROBLEM

0

US & EU patients suffering from
bile flow stagnation 
symptoms

10% of all liver transplants

have cholestasis as indication

0

US & EU patients with primary

sclerosing cholangitis without any

apprived treatment option

40% need a liver transplant

0

​US & EU patients with

primary biliary cholangitis,

500 transplants per year

OUR MISSION

​

Our mission is to prevent the need for transplantation 

​

​

THE SOLUTION

ClagalsiR –Claudin-3 GalNAc-siRNA

​

ClagalsiR is CALDRE’s proprietary claudin-3 targeting, liver specific GalNAc-siRNA that opens the paracellular barrier between liver hepatocytes.

 

Shown in our pre-clinical in vivo models, claudin-3 inhibition increases the water content in bile - lowering bile toxicity- and thereby lowered tissue necrosis and fibrosis

CHLORIDE IONS

Chloride ions stimulate bicarbonate release in bile ducts, increasing water influx and flow
 

BILE DUCT 

​Bicarbonate and water reduce bile toxicity, protecting the cells
