LONDON – Three large scale population surveys conducted between late June and the end of September have shown the prevalence of SARS-CoV-2 antibodies in England declined by 26.5% over three months. The findings rest on the results of more than 350,000 self-administered lateral flow blood tests that were carried out at home by volunteers who were randomly selected from general practitioner registers.
The ACTIV-3 phase III study testing Eli Lilly and Co.’s COVID-19 antibody candidate, LY-CoV555, which was paused two weeks ago following a participant’s unexplained illness, has now been halted, the company reported Oct. 26.
Despite an NIH move to pause enrollment in a trial testing Eli Lilly and Co.'s COVID-19 antibody candidate, LY-CoV555, after a participant's unexplained illness, at least three other studies of the candidate remain underway, the company said Oct. 14.
An NIH-sponsored phase III trial testing Eli Lilly and Co.'s SARS-CoV-2 neutralizing antibody candidate, LY-CoV555, alongside the Gilead Sciences Inc. antiviral Veklury (remdesivir) has been paused at the request of its data safety monitoring board, the company told BioWorld.
Astrazeneca plc said it has received about $486 million from the U.S. government to support the development and supply of a long-acting antibody combination under evaluation for the prevention and treatment of COVID-19. Phase III trials of the candidate, AZD-7442, are slated to begin later this month, the company told BioWorld. One trial will enroll more than 6,000 adults for the prevention of COVID-19 with additional trials set to enroll about 4,000 adults for the treatment of the infection, the Cambridge, U.K.-based company said.
Siemens Healthineers AG snagged a key role in the mystery playing out across the world's pandemic stage – what do antibody test results mean in terms of immunity to SARS-CoV-2 and how do different tests assessing different proteins compare? The U.S. CDC and the Joint Research Centre (JRC) of the European Commission tapped the Erlanger, Germany-based company to take the lead in developing a process to standardize antibody assays.
Through the use of sequencing data, researchers in Hong Kong presented a case study providing the strongest evidence yet that individuals can become reinfected with SARS-CoV-2 after clearing a first infection.
The pace of biopharma mergers and acquisitions has quickened with Johnson & Johnson’s $6.5 billion all-cash acquisition of Momenta Pharmaceuticals Inc. Bringing Momenta into the fold strengthens the Janssen Pharmaceutical Companies of Johnson & Johnson’s immune-mediated disease portfolio and grows its interest in autoantibody-driven disease therapies.
LONDON – A large scale population study has shown that home self-testing with low-cost lateral flow diagnostics is a valid way of tracking the COVID-19 pandemic. A total of 105,651 people across the U.K. tested themselves for SARS-CoV-2 antibodies with a fingerprick blood test as part of the REACT (REaltime Assessment of Community Transmission) study.
Much of the research on the immune response in patients with COVID-19 has focused on the humoral antibody response. Adaptive Biotechnologies Corp., on the other hand, has focused on cellular immunity to measure the T-cell response to infection with SARS-CoV-2.
