Previous studies have found that the effectiveness of vaccines can be increased with the knockdown of HBsAg using a small interfering RNA (siRNA). The efficacy of a bivalent mRNA vaccine in combination with the siRNA AD-66810, which targets the X gene expression in the hepatitis B virus (HBV) genome, was tested in a murine model of AAV/HBV by scientists from Clearb Therapeutics Inc.
Emory University has identified 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of SARS-CoV-2 infection (COVID-19).
A preclinical trial in mice and ferrets of an experimental mRNA vaccine against the H5 highly pathogenic avian influenza (HPAI) virus generated neutralizing antibodies and prevented severe illness and mortality of the animals.
An expert in hepatitis delta virus said Vir Biotechnology Inc.’s phase II findings with the monoclonal antibody tobevibart and the small interfering ribonucleic acid elebsiran in chronic disease could lead to a “change [in] the entire care cascade and paradigm.” Shares of Vir (NASDAQ:VIR) ended June 5 at $12.66, up $2.08, or 19.7%, on the clinical news.
Rome Therapeutics Inc. has synthesized 4’-halomethyl-cytidine phosphoramidate compounds acting as LINE-1 retrotransposable element ORF1 protein (L1RE1) and/or HERV-K reverse transcriptase inhibitors reported to be useful for the treatment of viral infections, cancer, inflammation, neurodegeneration and immunological disorders.
Exevir Bio BV has demonstrated that its antibodies are potent in neutralizing the SARS-CoV-2 variant JN.1, the parental strain of the currently most dominantly circulating variants worldwide.
Concurrent infection with hepatitis B virus (HBV) and hepatitis delta virus (HDV) may lead to cirrhosis, fulminant hepatitis or hepatocellular carcinoma faster than infection with HBV alone.
The persistence of hepatitis B virus (HBV) covalently closed-circular DNA (cccDNA) and integration of HBV DNA into the hepatocytes lead to chronic HBV infection. Current therapies achieve long-term viral suppression but, as HBV cccDNA is not eradicated, lifelong treatment is needed.
Annexon Inc.’s stock (NASDAQ:ANNX) climbed 31% June 4 following news that a single infusion of C1q protein complex inhibitor ANX-005 at the 30-mg/kg dose delivered a statistically significant 2.4-fold improvement in Guillain-Barré syndrome patients. Shares closed at $5.99, up $1.41.
