Elebsiran sodium

(Synonyms: VIR-2218 sodium)

고객리뷰

Based on 1 Customer Validation

Elebsiran (VIR-2218) sodium is a siRNA that targets and degrades hepatitis B virus (HBV) and hepatitis D virus (HDV) RNA transcripts. Elebsiran sodium leads to a significant decrease in HBV surface antigen (HBsAg) and a reduction in viral load. Elebsiran sodium binds to the sialic acid-depleted glycoprotein receptor (ASGPR) on the surface of liver cells through the GalNAc ligand, achieving liver-targeted delivery and demonstrating improved liver safety. Elebsiran sodium can be used for the study of chronic HBV/HDV infections.

Biological Activity

제품 설명

In Vitro

Elebsiran (0.1 pM-100 nM) sodium effectively reduces HBsAg and the infectivity of HDV, and when combined with Tobevibart (HY-P990015) for treatment, it shows an additive effect^[1].
Elebsiran sodium exhibits comparable antiviral activity to ALN-HBV in HepG2.2.15 cells but its cytotoxicity is significantly reduced^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Parmacokinetics

Species	Dose	Route	T_max	C_max	AUC_last	T_1/2
Monkey^[2]	10 mg/kg	s.c.	24 h	135000 ng/g	37200000 h·ng/g	160 h
Rat^[2]	10 mg/kg	s.c.	7 h	97000 ng/g	6610000 h·ng/g	93.1 h

In Vivo

Elebsiran (9 mg/kg, s.c., single dose) sodium possess antiviral activity against HBV and HDV in mice^[1].
Elebsiran (12-100 mg/kg, s.c., 5 doses on Days 0, 21, 28, 35, and 42) sodium does not cause a significant increase in ALT in all dosage groups and demonstrates high liver safety in mice^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

HBV/HDV-coinfected liver-chimeric model established in liver-chimeric mice^[1]
Dosage:

9 mg/kg alone or with 15 mg/kg muHBC34 (the murinized version of Tobevibart)
Administration:

Subcutaneous injection (s.c.), single dose
Result:

Significant decreased of 0.6 log for HBsAg, 0.5 log for HBV DNA and 0.7 log for HDV RNA compared to the vehicle control on day 14 post-treatment.
Led to the strongest reductions in HBsAg, HBV DNA and HDV RNA levels relative to the vehicle group with muHBC34.

Animal Model:

Chimeric mouse model established male PXB mice at 12 to 18 weeks^[3]
Dosage:

12 mg/kg, 36 mg/kg, and 100 mg/kg
Administration:

Subcutaneous injection (s.c.), on Days 0, 21, 28, 35, and 42
Result:

Observed a clear dose-dependent increase in hALT1 levels, whereas no relationship between hALT1 and dose level.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
