How T Cell Tests Could Trump Antibody Tests in the Detection of COVID-19

XTalks

A new type of test based on detection of activated T cells may prove to have greater utility in determining whether someone has had a COVID-19 infection compared to a traditional antibody test. The cell-based tests are designed to identify specific T cells that are activated in response to a pathogen — which in this case would be SARS-CoV-2.

Broadly neutralizing antibodies could provide immunity against SARS-CoV-2 variants

The Pharma Data

Two broadly neutralizing antibodies show great promise to provide long-acting immunity against COVID-19 in immunocompromised populations according to a paper published June 15 in the Journal of Experimental Medicine (JEM). The two antibodies also were fully active against Alpha, Beta, Gamma, and Delta variants. 2 subtypes.

Roche launches new quantitative antibody test to measure SARS-CoV-2 antibodies, to support the evaluation of vaccines

The Pharma Data

The new Elecsys Anti-SARS-CoV-2 S test can quantitatively measure the level of antibodies against SARS-CoV-2 in patients who have been exposed to the virus. The test targets antibodies against the spike protein. This is the focus of vaccines in development and convalescent plasma therapy.

Evusheld long-acting antibody combination recommended for approval in the EU for the pre-exposure prophylaxis (prevention) of COVID-19

The Pharma Data

AstraZeneca’s Evusheld (tixagevimab co-packaged with cilgavimab), a long-acting antibody combination, has been recommended for marketing authorisation in the European Union (EU) for the pre-exposure prophylaxis (prevention) of COVID-19 in a broad population of adults and adolescents aged 12 years and older weighing at least 40 kg.

Evusheld long-acting antibody combination approved in the EU for pre-exposure prophylaxis (prevention) of COVID-19 in a broad population

The Pharma Data

Evusheld significantly reduced the risk of developing symptomatic COVID-19 in PROVENT Phase III trial, with protection lasting at least six months Evusheld retains neutralising activity against the Omicron BA.2 2 subvariant, now the dominant strain in Europe. 1-3 Evusheld was generally well-tolerated in the trial.
