VIR HBV—>48w VIR-2219 +peg-IFN—>31% HBs seroconverion:

https://www.globenewswire.com/news-release/2022/11/06/2549180/0/en/Vir-Biotechnology-Presents-New-Data-Evaluating-the-Potential-for-VIR-2218-and-VIR-3434-to-Achieve-a-Functional-Cure-for-Chronic-Hepatitis-B-Virus-HBV-Infection.html

The 31% figure is impressive insofar as peg-IFN by itself has a 48w seroconversion rate of only 5-10%. Of course, a 48w regimen of VIR-2219 + peg-IFN won’t be any easier to tolerate than 48w of peg-IFN monotherapy, so this regimen is still far from the ultimate answer for treating chronic HBV.

VIR has started testing the triple combination of VIR-2219 (siRNA) + VIR-3434 (mAb) + peg-IFN; initial data are expected in 2H23.
