Mabwell Bioscience Co. Ltd. raised ¥3.48 billion ($547.9 million) in a Shanghai STAR Market IPO on Jan. 18 to support company R&D efforts and plans to build an antibody production plant. Though oversubscribed, the offering got a cool market reception, with shares plunging nearly 30% from a ¥32 open (US$27.96), then closing at ¥24.50 on the first day of trading before recovering slightly to ¥27.40 on Jan. 20.

LONDON – Four decades of academic research at the University of California, San Francisco, is to be translated through to the clinic with funding from a €1 million (US$1.2 million) European Commission grant. The money, awarded to a Dutch/German consortium will fund the generation and optimization of antibodies designed to neutralize oxidized phospholipids that mediate inflammatory changes in a swathe of diseases. The consortium that won the Eurostars award is led by Oxitope Pharma BV.

Tentarix Biotherapeutics LP broke cover with $50 million in series A funding to take forward an industrialized flow cytometry platform that enables it to screen rapidly for multifunctional antibody-based drugs.

Cambridge, U.K.-based Astrazeneca plc has new data from its long-acting COVID-19 antibody combination, AZD-7442, which aims to provide longer protection, potentially for up to a year. Latest data show the intramuscularly injected drug achieved a statistically significant reduction in severe COVID-19 or death compared to placebo in non-hospitalized patients with mild to moderate symptomatic disease.

Trimers of nanobodies, a simpler form of antibody made by some animal species, were effective at preventing and treating COVID-19 in preclinical studies, researchers reported in the Sept. 22, 2021, issue of Nature Communications. The findings, along with others, could form the basis of an inhaled biologics treatment for COVID-19 and, ultimately, other respiratory diseases.

Access Biologicals LLC brought online newly released seroconversion panels that measure the level of antibodies against SARS-CoV-2 in blood samples, allowing researchers to determine vaccine efficacy. The panels can detect the point when seroconversion occurs and assess the efficacy of a vaccine against new and existing strains of the novel coronavirus. To build the panels, the Vista, Calif.-based company collected blood samples prior to vaccination and after the first and second doses. The plasma was then tested for IgG antibodies to the S1 and S2 spike proteins of the novel coronavirus using enzyme-linked immunosorbent assays (ELISA) and chemiluminescent assays (CLIA).
