Antisense oligodeoxynucleotides: the certain but limited efficacy and the uncovering mechanisms for the cure of chronic hepatitis B
(PubMed, Zhonghua Gan Zang Bing Za Zhi)
- "Particularly in the report of phase IIb clinical trial of Bepirovirsen (GSK3228836), approximately 9-10% patients with low baseline serum HBsAg (> 100 IU/ml & < 3 000 IU/ml) achieved functional cure after 24 weeks' of Bepirovirsen treatment. After reviewing the results of other clinical trials, one would be impressed to know that ALG-020572 (Aligos), RO7062931 (Roche) and GSK3389404 (GSK) all failed to sufficiently suppress serum HBsAg expression though the hepatocyte-targeted delivery of these ASOs were enhanced via N-acetyl galactosamine conjugation...Eventually the serum HBsAg declines in most participants and even disappears in a small fraction of patients with low baseline HBsAg level, via attack the infected hepatocytes evidenced by the aberrant elevation of ALT. Nevertheless, the functional cure of CHB remains a challenging issue and more efforts are needed."

A Single Ascending Dose Study of Single-Stranded Oligodeoxyribonucleotide RO7062931 in Chinese Healthy Volunteers.
(PubMed, Clin Transl Sci)
- "PK data suggested that ASGPR saturation had commenced between doses of 2.0 mg/kg and 4.0 mg/kg. Results were broadly consistent with observations in primarily white subjects in the global first in-human study of RO7062931."

[VIRTUAL] RO7062931 anti-sense oligonucleotide phase 1 study demonstrates target engagement in patients with chronic hepatitis B on established nucleos(t)ide therapy
(EASL-ILC-I 2020)
- P1 | "RO7062931 administered over 4-weeks, at doses of up to 4mg/kg, in CHB patients is safe, well tolerated, and demonstrates target engagement by antiviral activity."

Author Reply: Is the HBsAg response to RO7062931 an antisense effect?
(PubMed, Hepatology)
- "Firstly, Dr Vaillant proposes RO7062931 should have exhibited greater HBsAg reductions, given the efficient RO7062931 liver uptake, rapid turnover of HBsAg, and rapid protein reductions observed with GalNAc-ASOs in other therapeutic indications. We find this reasoning unsatisfactory, primarily as there should be no expectations of similar potency for GalNAc-ASOs targeting different mRNA species."

Letter to the editor: Is the HBsAg response to RO7062931 an antisense effect?
(PubMed, Hepatology)
- "Exemplary studies (2, 3) illustrate a rapid and uniform ~1 log protein reduction within 15 days in all subjects, occuring with only a single dose and saturating with weekly to monthly dosing from 60mg (0.9 mg/kg) to 90mg (1.4 mg/kg). Given the rapid turnover of HBsAg (4, 5), target engagement with RO7062931 should be accompanied by similar HBsAg responses."
