(Reuters) -AstraZeneca’s experimental COVID-19 drug has helped reduce the danger of extreme illness or dying in a late-stage research, the British drugmaker mentioned on Monday, a lift to its efforts to develop coronavirus medicines past vaccines.

The drug, a cocktail of two antibodies referred to as AZD7442, lowered the danger of extreme COVID-19 or dying by 50% in non-hospitalised sufferers who’ve had signs for seven days or much less, assembly the primary objective of the research.

AstraZeneca (NASDAQ:)’s remedy, delivered through injection, is the primary of its form to indicate promise each as a preventative drugs and as a therapy for COVID-19 following a number of trials. It’s designed to guard individuals who do not need a robust sufficient immune response to vaccines.

“These optimistic outcomes present {that a} handy intramuscular dose of AZD7442 may play an necessary position in serving to fight this devastating pandemic,” Hugh Montgomery, the trial’s principal investigator, mentioned in an announcement.

Related therapies made with a category of medication referred to as monoclonal antibodies are being developed by Regeneron (NASDAQ:), Eli Lilly (NYSE:) and GlaxoSmithKline (NYSE:) with companion Vir. These therapies are authorised for emergency use in america for treating mild-to-moderate COVID-19.

AstraZeneca, whose COVID-19 vaccine has been extensively used globally, requested U.S. regulators final week to grant emergency use authorisation for AZD7442 as a preventative remedy.

AstraZeneca is submitting information from varied AZD7442 research to world well being regulators, a spokeswoman mentioned on Monday.

“We’ll be persevering with discussions with regulators round this new information,” she mentioned of Monday’s trial outcomes.

The trial came about throughout 13 international locations and concerned greater than 900 grownup contributors, with one half receiving AZD7442 and the remainder a placebo. Full trial outcomes will likely be submitted for publication in a peer-reviewed journal, AstraZeneca mentioned.

AZD7442 comprises laboratory-made antibodies designed to linger within the physique for months to include the virus in case of an an infection. A vaccine, in distinction, depends on an intact immune system to develop focused antibodies and infection-fighting cells.

“An early intervention with our antibody can provide a major discount in development to extreme illness, with continued safety for greater than six months,” mentioned Mene Pangalos, government vice chairman at AstraZeneca.

Whereas Monday’s outcomes cowl using AZD7442 in non-hospitalised sufferers, a separate trial can also be learning its use as a therapy for hospitalised COVID-19 sufferers.

Different antibody cocktail therapies for COVID-19 have proven diverse levels of success.

Regeneron’s remedy confirmed 72% safety in opposition to symptomatic an infection within the first week, and 93% after that. GSK-Vir’s confirmed a 79% discount within the threat of hospitalisation or dying because of any trigger, whereas Lilly’s remedy confirmed a 70% discount in viral load at day seven in comparison with a placebo.
