Implication

Randomized trial demonstrates reduced inflammation and prolonged survival in MDS mice using Tmprss6 silencing.

Key Points

The study aims to evaluate the effects of Tmprss6 silencing on iron-induced inflammation and survival in a mouse model of Myelodysplastic Syndromes (MDS).
Utilized hepatocyte-targeted silencing of Tmprss6 with GalNAc-conjugated siRNA (SLN124) in NHD13 mice.
Administered SLN124 (3 mg/kg) monthly subcutaneously or deferiprone (1.25 mg/mL) orally.
Assessed tissue iron deposition and inflammasome activation via ASC-speck formation in CD45 + hematopoietic cells.
SLN124 treatment significantly reduced tissue iron deposition and ASC-speck formation, more than deferiprone.
30% of SLN124-treated mice survived beyond 450 days, while all controls and deferiprone-treated mice died by Day 420.
SLN124 delayed disease progression in MDS mice, indicating a strong therapeutic effect.
