New monoclonal antibody shows promise for severe asthma

A new monoclonal antibody therapy shows promise in offering an alternative treatment for patients suffering from moderate-to-severe asthma. Research led by Michael E. Wechsler, MD, MMSc, director of the National Jewish Health Cohen Family Asthma Institute, found that itepekimab was safe and effective in a phase 2 trial published online today in the New England

Sexually dimorphic placental antibody transfer during SARS-CoV-2 infection

Sex-based differences in COVID-19 disease transmission, severity, and mortality have been reported since the early stages of the pandemic in infants, with the underlying mechanism accounting for these differences not yet fully understood. In a paper recently published in the journal Science Translational Medicine by Bordt et al. (October 19th, 2021), maternal SARS-CoV-2 infections are

SARS-CoV-2 infection aided by antibody-dependent enhancement

The coronavirus disease 2019 (COVID-19) pandemic spread rapidly around the world, leading to lockdowns, social distancing measures, and millions of deaths. However, with the help of mass vaccination campaigns and monoclonal antibody treatments, the transmission of the disease is beginning to slow down. Vaccines rely on the immune systems ability to produce specific antibodies –

Novel combination therapy may prolong viral suppression in patients with HIV

A novel combination treatment may increase the ability of monoclonal antibodies to control viral infection in patients diagnosed with HIV, according to a Northwestern Medicine study published in Science Translational Medicine. This really demonstrates that that we should combine broadly neutralizing antibodies with other immunostimulatory agents, especially those that may impact immune response. If we

Phase I clinical study evaluates safety and pharmacokinetics of ExeVir's COVID-19 neutralizing antibody

ExeVir, which is developing single domain antibody therapies providing broad protection against viral infections, today announces that the first subjects have been dosed in a Phase I clinical study of XVR011, its llama-derived antibody for the treatment and prevention of COVID-19.

Researchers repurpose pre-existing anti-SARS-CoV antibody to develop potent neutralizing antibody against SARS-CoV-2

A team of scientists from the United States has recently engineered a pre-existing anti-severe acute respiratory syndrome coronavirus (SARS-CoV) neutralizing antibody to increase its binding affinity for the spike receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The engineered antibody demonstrates high potency in neutralizing SARS-CoV-2 and preventing infection in animals. Study:

Third monoclonal antibody drug given FDA approval for Covid-19

FDA authorizes third Covid antibody treatment that cuts risk of hospitalization or death by 85% Sotrovimab is the third monoclonal antibody drug to receive approval for use fighting Covid-19, fifth drug overall Believed to be able to reduce Covid hospitalizations and deaths by 85 percent   The drug will be the first to have a point

Updated Moderna vaccines neutralize South African SARS-CoV-2 variant in mice

Researchers in the United States have conducted a pre-clinical study demonstrating the efficacy of two updated versions of the Moderna mRNA-1273 vaccine against variants of severe acute respiratory syndrome coronavirus 2 – the agent that causes coronavirus disease 2019 (COVID-19). Study: Variant SARS-CoV-2 mRNA vaccines confer broad neutralization as primary or booster series in mice

REUTERS/Mike Segar(Reuters) -Eli Lilly and Co said on Monday it had a revised agreement with the U.S. government for its COVID-19 antibody drug, bamlanivimab,

Current monoclonal antibodies less potent against SARS-CoV-2 variants

The coronavirus disease (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to wreak havoc across the globe. Scientists are racing to develop effective therapeutic regimens to combat the infection. One of therapy currently used to stimulate a robust immune response against the virus is monoclonal antibodies, a treatment used for

Immune response to SARS-CoV-2 may be limited by a set of genes

Neutralizing antibodies develop within two weeks of a SARS-CoV-2 infection, but their durability and intensity can vary by individual, prompting concerns about the prospects of long-lasting immunity and efficacy of COVID-19 vaccines. In a PLOS ONE paper, published online February 11, 2021, researchers at University of California San Diego School of Medicine report that individual

Detection of emerging SARS-CoV-2 variant in New York

Researchers at the California Institute of Technology in Pasadena have developed a software tool called "Variant Database" that has detected an emerging lineage of severe acute respiratory coronavirus 2 (SARS-CoV-2) isolates in New York. The novel SARS-CoV-2 virus is the agent responsible for the coronavirus disease 2019 (COVID-19) pandemic that continues to sweep the globe
