An international team of researchers has created two bat stem cell lines that reveal an unusual number of viral sequences in bat cells compared with those of other mammals. Writing in an article posted online Feb. 21, 2023, in Cell, the scientists suggested that the unusual amount of viral genetic material found in the bat stem cells could explain why these mammals are largely unaffected by most viral infections, despite being able to transmit them.
Anthony Fauci has retired from his position as director of the National Institute of Allergy and Infectious Diseases (NIAID) and as chief medical advisor to the U.S. president. But Fauci, who has advised every president since Ronald Reagan, continues to share his encyclopedic knowledge with the HIV research community, as he has since the beginning of the HIV pandemic. Fauci co-founded the first National Conference on Human Retroviruses and related infections in 1993. At the Opening Session of the 30th edition of the Conference on Retroviruses and Opportunistic Infections (CROI), he highlighted the advances that have collectively extended the life expectancy of newly diagnosed patients by decades.
The A’s have it but the B’s don’t in Moderna Inc.’s pivotal phase III study of mRNA-1010, a seasonal flu vaccine for adults living in the southern hemisphere. Interim results showed the vaccine achieved superiority on seroconversion rates for influenzas A/H3N2 and A/H1N1, superiority on geometric mean titer ratios for influenza A/H3N2 and noninferiority on geometric mean titer ratios for influenza A/H1N1. However, noninferiority was not met for the endpoints against the influenza B/Victoria- and B/Yamagata-lineage strains.
Ascletis Pharma Inc. presented subgroup data from a phase II trial showing its subcutaneous PD-L1 antibody envafolimab (ASC-22) was able to functionally cure chronic hepatitis B, according to hepatitis B surface antigen decline following 24-week treatment.
Erytech Pharma AS, repositioning itself to recover from a tough phase III cancer study failure in 2021, will merge with Pherecydes Pharma SA, which specializes in precision phage therapy for treating resistant and/or complicated bacterial infections.
Bavarian Nordic A/S plans to buy two travel vaccines plus a phase III chikungunya vaccine candidate from Emergent Biosolutions Inc. for about $380 million. Emergent will receive a $270 million up-front payment and perhaps as much as $110 million in future milestone payments. The vaccines are Vivotif, for preventing typhoid fever, and Vaxchora, for preventing cholera caused by Vibrio cholerae serogroup O1. Both oral vaccines have U.S. FDA and European approvals.
Biomedical Research & Bio-Products (Bio&Bio) AG is laying plans for a phase III trial of its vaccine for preventing methicillin-resistant Staphylococcus aureus infections from sparking toxic shock syndrome, after delivering phase II data showing good safety and immunogenicity.
Zhimeng Biopharma Inc. found a global partner for its hepatitis B virus (HBV) program, licensing rights to GSK plc for CB-06, an oral small-molecule Toll-like receptor 8 agonist. Pending positive data from an ongoing phase I study, GSK will gain rights to develop, manufacture and commercialize the drug for chronic HBV infection, either for use in combination or as a sequential treatment with bepirovirsen.
Changchun Bcht Biotechnology Co. Ltd. has obtained marketing approval for its live attenuated zoster vaccine in China, making it the first approved shingles vaccine developed by a Chinese company. An injectable of 0.5 ml per dose, it is designed for adults ages 40 and older and will go up against GSK plc’s Shingrix vaccine.
Low enrollment in a phase III trial and a missed primary endpoint sent Aridis Pharmaceuticals Inc.’s shares tumbling by 35% on Jan. 26, although the company’s AR-301 (tosatoxumab) showed superior efficacy over the control group in Staphylococcus aureus ventilator-associated pneumonia (VAP) patients.
