oligonucleotides targeting miR-21 (anti-miR-21) reduces the severity of
fibrosis and improves renal function in a rodent model of Alport syndrome.
Regulus' miR-21 therapeutic development program, which is partnered with
Sanofi, is currently in preclinical testing for both kidney fibrosis and
hepatocellular carcinoma.

"We are pleased to present at Kidney Week and believe these data further
validate that anti-miR-21 is a potential new therapy for human kidney
disease," said Neil W. Gibson, Ph.D., Chief Scientific Officer of Regulus.
