LONDON,\u00a0United Kingdom\u00a0(AFP) \u2014 Drug firm AstraZeneca on Friday announced positive results from a trial of a treatment for COVID-19 symptoms.<\/p>\n
The drug, made from a combination of two antibodies, was initially developed as a treatment for those who had already been exposed to the disease.<\/p>\n
A new trial of 5,197 participants who had not been exposed showed a 77-per cent reduced risk of developing symptomatic disease, with no severe cases recorded, Astra said in a statement.<\/p>\n
A previous trial of the AZD7442 drug had shown it only reduced the risk of developing symptoms by 33 per cent, which it concluded in June was not statistically significant.<\/p>\n
The data show that one dose could “quickly and effectively prevent symptomatic COVID-19”, said Myron Levin, principal trial investigator.<\/p>\n
“With these exciting results, AZD7442 could be an important tool in our arsenal to help people who may need more than a\u00a0vaccine\u00a0to return to their normal lives.”<\/p>\n
It is hoped that the drug could be used alongside vaccines for those who need more protection, affording up to 12 months of defence.<\/p>\n
Participants in the trial were adults who were poor responders or intolerant to\u00a0vaccines, or who had increased risk of infection because of their locations or circumstances.<\/p>\n
The US government has funded the development of AZD7442 and has agreements to receive 700,000 doses.<\/p>\n
The company will now send the data to health authorities for potential emergency use authorisation or conditional approval.<\/p>\n
AstraZeneca already makes the most widely offered\u00a0vaccine\u00a0in the UK, although those under 40 are offered Pfizer or Moderna instead because of concerns over possible side effects.<\/p>\n
