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

in need of 2nd line treatment

500 transplants per year

OUR MISSION

Our mission is to prevent the need for liver transplantation 

THE SOLUTION

ClagalsiR –Claudin-3 GalNAc-siRNA

ClagalsiR is a claudin-3 targeting, liver specific GalNAc-siRNA developed to selectively open 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
