UPDATE 1-Russia approves trial of AstraZeneca COVID-19 vaccine - registry filing

(Adds context)

MOSCOW, Aug 21 (Reuters) - Britain’s AstraZeneca has received regulatory approval to conduct part of a Phase III trial of its potential COVID-19 vaccine in Russia, a filing in the Russian registry of clinical trials showed on Friday.

The trial of the AZD1222 vaccine will involve 150 participants and will be handled by four medical facilities in St. Petersburg and Moscow, the filing, dated Friday, showed.

Moscow has previously agreed a deal with AstraZeneca to manufacture the potential vaccine, developed in tandem with Oxford University, at the facilities of Russian firm R-Pharm.

The British drugmaker said in a statement last week that late-stage trials of its vaccine were ongoing in Britain and in Brazil, an early-stage trial was progressing in South Africa, and that further trials were planned in the U.S., Japan and Russia.

Russia is also developing several potential COVID-19 vaccines domestically, with late-stage trials of the front-runner candidate, nicknamed ‘Sputnik-V’, set to begin next week. (Reporting by Polina Ivanova; Additional reporting by Ludwig Burger; Editing by Susan Fenton;Editing by Elaine Hardcastle)
